Answer:
y - 1 = 3/2 (x + 10)
Step-by-step explanation:
Point-slope form of the equation of a line is a fill-in-the-blank shortcut to write an equation. If you know a point and the slope of a line you can fill in that info and voila! you have the equation.
Here is Point-slope equation:
y - Y = m(x - X)
Because the point given (-10,1) is in the form (X,Y), fill in -10 for X and 1 for Y.
The slope given is 3/2, fill that in for m.
y - Y = m(x - X)
y - 1 = 3/2 (x - -10)
y - 1 = 3/2 (x + 10)
The equation is
y - 1 = 3/2 (x + 10)
39) A bike road race starts at an elevation of500feet and passes through 5 stages where the elevation changes by -139 feet, -63feet, 197feet, 27feet, and -327feet. At what elevation does the race end.
The answer is 195 feet please show the work to get the answer?
The elevation at which the race ends is given by the equation A = 195 feet
What is an Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the elevation at which the race ends be A
Now , the equation will be
The bike road race starts at an elevation of 500 feet
So , the initial elevation = 500 feet
The number of stages = 5 stages
The elevation at first stage = -139 feet
The elevation at second stage = -63 feet
The elevation at third stage = 197 feet
The elevation at fourth stage = 27 feet
The elevation at fifth stage = -327feet
So , the total elevation of all the stages during the bike race = initial elevation + elevation at first stage + elevation at second stage + elevation at third stage + elevation at fourth stage + elevation at fifth stage
Substituting the values in the equation , we get
The total elevation of all the stages during the bike race = elevation at which the race ends A
So ,
Elevation at which the race ends A = 500 + (-139) + (-63) + (197) + (27) + (-327)
On simplifying the equation , we get
Elevation at which the race ends A = 500 - 305
Elevation at which the race ends A = 195 feet
Therefore , the value of A is 195 feet
Hence , the race ends at an elevation of 195 feet

what would be themissing side length
The missing side length is 5.7.
What would be themissing side length?The missing side length AB, can be calculated using the Pythagorean Theorem.The Pythagorean Theorem states that in a right triangle, the sum of the squares of the lengths of the two sides adjacent to the right angle (A and B) is equal to the square of the length of the hypotenuse (C).In other words, AB^2 + BC^2 = AC^2.In this case, AB^2 = AC^2 - BC^2, or AB^2 = 6.7^2 - 3^2, which simplifies to AB^2 = 44.89.Taking the square root of both sides yields AB = 6.7.Therefore, the missing side length, AB, is 6.7.The missing side length of a triangle with sides of lengths a, b, and c is calculated by using the Pythagorean theorem, which states that a^2 + b^2 = c^2. In this case, we are given that side c is 3, and side a is 6.7.Using the Pythagorean theorem, we can solve for side b by rearranging the equation to read b^2 = c^2 - a^2. Plugging in our known values, we get b^2 = 9 - 44.89, or b^2 = -35.89.Since the square root of a negative number is not a real number, this implies that there is no real number solution for b, and therefore the missing side length of the triangle is not possible.

Find the slope (-7,4) and (-7,-8)
Answer: The slope for this line is not defined.
Step-by-step explanation: We can find the slope of a line using the formula m = y2 -y1/x2 - x1
here, (x1,y1) = (-7,4)
and, (x2,y2) = (-7,-8)
now, m= -8-4/-7+7
m = -12/0
So, the slope for this line is not defined as we are getting zero in the denominator.

Hence total number of women=5x/8
No. of men having brown eyes=2/3*3x/8=x/4
Total no. of people having brown eyes=3x/4
No.of women having brown eyes
=3x/4 -x/4=2x/4=x/2
No. of women who don't have brown eyes= 5x/8-x/2 = x/8
So the fraction is x/8x= 1/8
Step-by-step explanation:
Answer: 28 children
What is a ratio?A ratio has two or more numbers that symbolize relation to each other. Ratios are used to compare the numbers, and you can compare them using division.
First, we would need to figure out the total number of students. To do this, we can divide 84 by 3, then add that to the total.
84 ÷ 3 = 28
28 + 84 = 112
This means that there are 112 students in the classroom.
If 3/4 of the children in the school have blue eyes, we know that 1/4 of the children will have brown eyes. We can convert 1/4 into a decimal, or into a percentage, to get the number of children with brown eyes.
1/4 = 0.25 = 25%
To figure out how much 25% of 112 is, we can simply multiply 112 by 0.25.
112 × 0.25 = 28
So, this means that there are 28 children with blue eyes in the school.

We define a linear equation.In algebra, a linear equation is one that of the form y=mx+b. The slope is B, and the y-intercept is m. Since y and x are variables, the previous sentence is frequently referred to as a "linear equation with two variables." Bivariate linear equations are linear equations with two variables. Linear equations can be found in many places, including 2x - 3 = 0, 2y = 8, m + 1 = 0, x/2 = 3, x + y = 2, and 3x - y + z = 3. When an equation has the structure y=mx+b, where m denotes the slope and b the y-intercept, it is referred to as being linear.

Step-by-step explanation:
For part a, all you are doing is adding the polynomials together. They already set up the boxes in standard form, so all you need to do is add each like term as I wrote out in the answer. The degree is then going to be the first exponent that you see once the polynomial is in standard form, which is 4.
For part b, you are now subtracting the polynomials. Again, it is set up for you in standard form. There is no x^3 terms because they cancel out, but you basically subtract each like term from another, and remember to distribute the subtraction sign (it acts as a -1) across the parenthesis. The degree is the first exponent you see, and that is 4.

Right triangle XYZ has legs of length XY = 12 and YZ 6. Point D is chosen at random within the triangle XYZ. What is the probability that the area of triangle XYD is at most 20?
Step-by-step explanation:
a probability is always
desired cases / totally possible cases.
now in our case the totally possible area is the area of the triangle XYZ (when D = Z).
the desired case is the area of 20 (which contains also the possibilities of smaller areas).
so, the probability is 20/area.
now, let's find the area of XYZ :
Pythagoras tells us the length of the Hypotenuse :
XZ² = XY² + YZ² = 12² + 6² = 144 + 36 = 180
XZ = sqrt(180)
the area based on all 3 sides we get via Heron's formula
s = (a+b+c)/2
A = sqrt(s(s-a)(s-b)(s-c))
s = (12+6+sqrt(180))/2 = 9 + sqrt(180/4) = 9 + sqrt(45)
sqrt(180) = 2×sqrt(45)
A = sqrt((9+sqrt(45))(-3+sqrt(45))(3+sqrt(45))(9-sqrt(45)))
(a+b)(a-b) = a² - b²
so,
(9+sqrt(45))(9-sqrt(45)) = 81 - 45 = 36
(-3+sqrt(45))(3+sqrt(45)) = 45 - 9 = 36
A = sqrt(36×36) = 6×6 = 36
the probability that the area of XYD is max. 20 is
20/36 = 5/9

If Raj was getting a 5% commission, he would make 24000 * 5% = $<<240005.01=1200>>1200 on $24,000 of sales.
If he is now getting a 6.5% commission, he will make 24000 * 6.5% = $<<240006.5.01=1560>>1560 on $24,000 of sales.
Thus, Raj will make 1560 - 1200 = $<<1560-1200=360>>360 more on $24,000 of sales with his new commission rate of 6.5% than he did with his old commission rate of 5%.

Answer the following questions below:
1. Find a direction vector of L
2. Find a parameterization of L.
3. Find the two points on L that are at distance 2 away from A.
4. Find a unit speed parameterization of L.
Answer:
(4, -5, 5)L = (1+4t, 2-5t, -1+5t)(1+4√66/33, 2-5√66/33, -1+5√66/33), (1-4√66/33, 2+5√66/33, -1-5√66/33)(1-2t√66/33, 2+5√66/66, -1-5√66/66)Step-by-step explanation:
Given L is the line through A(1, 2, -1) and B(5, -3, 4), you want its direction vector, a parameterization of L, 2 points on L that are 2 units from A, and a unit speed parametrization of L.
1. Direction vectorA direction vector for L will be the vector AB.
[tex]\overrightarrow{AB}=B-A=(5,-3,4)-(1,2,-1)\\\\\boxed{\overrightarrow{AB}=(4, -5,5)}[/tex]
2. Parameterized lineThe parameterized equation will be ...
[tex]L=A+t\cdot\overrightarrow{AB}\\\\\boxed{L=(1+4t,2-5t,-1+5t)}[/tex]
3. Distance 2The direction vector has length √66, so we can find two points on L that are 2 units from A by using t = ±2/√66 in the parameterized equation.
Here, they are:
P1 = L(2/√66) = (1 +8/√66, 2 -10/√66, -1 +10/√66)
P2 = L(-2/√66) = (1 -8/√66, 2 +10/√66, -1 -10/√66)
In the Answer section above, these are written with rationalized denominators.
4. Unit speedThe unit speed parametrization uses the unit direction vector instead of the unnormalized direction vector in the parameterized equation. Effectively, t is scaled by a factor of 1/√66.
L = (1 +4t/√66, 2 -5t/√66, -1 +5t/√66)
In the Answer section above, this is written with rationalized denominators.
You might notice here that it is easier to answer part 3 if you have this equation. You need only substitute t=±2 to get the points 2 units from A.
