What is the slope of a line perpendicular to the line -2x + 9y = 8?
Answer:
-9/2
Step-by-step explanation:
To make a slope perpendicular, you must find the slope in a y = mx+b format where the slope is easy to find. Add 2x to the opposite side and then divide the entire right side of the equation by 9 to get y = 2/9x +8/9. A perpendicular slope is just a negative reciprocal of the slope, so make 2/9 negative and flip around the numerator and denominator to get a perpendicular slope of -9/2. Hope that helps!
a line passes through the points ( -4,3) and (0,0). what is the slope of the line?
Answer:
The slope is -3/4 or -0.75
Step-by-step explanation:
You can solve this using the slope of a line formula:
[tex]m=\frac{rise}{run}=\frac{y_{2}-y_1 }{x_2-x_1}[/tex]
m = slope
[tex](x_1,y_1)[/tex] = coordinates of first point in the line
[tex](x_2,y_2)[/tex] = coordinates of second point in the line
Now all you have to do is plug your numbers in and solve!
Write f(x) = 2x2 – 44x 185 in vertex form. to write f(x) = 2x2 – 44x 185, factor out from the first two terms. next, form a perfect square trinomial keeping the value of the function equivalent: f(x) = 2(x2 – 22x 121) 185 – 242 the function written in vertex form is f(x) = (x – )2 .
The quadratic function given when converted to vertex form will be: [tex]f(x) = 2(x-11)^2 -57[/tex]
What is vertex form of a quadratic equation?If a quadratic equation is written in the form
[tex]y=a(x-h)^2 + k[/tex]
then it is called to be in vertex form. It is called so because when you plot this equation's graph, you will see vertex point(peak point) is on (h,k)
We first take out coefficient of x squared, and then inside the bracket, we try to make perfect square like situation.
For this case, the given quadratic function is:
[tex]f(x) =2x^2 -44x + 185\\[/tex]
Converting this to the vertex form, we get:
[tex]f(x) =2x^2 -44x + 185\\\\f(x) = 2(x^2 -22x) + 185\\f(x) = 2(x^2 -2 \times 11 \times x + 11^2 - 11^2) + 185\\f(x) = 2((x-11)^2 -121) + 185\\f(x) = 2(x-11)^2 -242 + 185\\f(x) = 2(x-11)^2 -57[/tex]
Thus, the quadratic function given when converted to vertex form will be: [tex]f(x) = 2(x-11)^2 -57[/tex]

If PT=u and QS=u–28, what is the value of u?
Answer:
u = 56
Step-by-step explanation:
the midsegment QS is half the length of the third side PT , that is
QS = [tex]\frac{1}{2}[/tex] PT ( substitute values )
u - 28 = [tex]\frac{1}{2}[/tex] u ( multiply through by 2 to clear the fraction )
2u - 56 = u ( subtract u from both sides )
u - 56 = 0 ( add 56 to both sides )
u = 56

Liz makes and sells necklaces. It costs her $40 for the supplie s to make 50 necklaces. How much must she sell each one for in order to make a profit of at least $250?
Using proportions, it is found that she must sell each necklace for at least $5.80 in order to make a profit of at least $250.
What is a proportion?A proportion is a fraction of a total amount
In this problem, it costs her $40 to make 50 necklaces. She wants a profit of at least $250, hence the 50 necklaces should sell for at least $250 + $40 = $290.
Hence, the minimum price for each one is given by:
$290/50 = $5.80.
She must sell each necklace for at least $5.80 in order to make a profit of at least $250.

The Edwards family spends $800 per month on groceries for their family. If this is 18% of their monthly budget, then what is their monthly budget?
Round to the nearest cent (hundredths place).
I suck at math so like yeah and i really need this good grade please
Answer:
$444.44
Step-by-step explanation:
Let the monthly budget of Edward family be $x.
-> 18% of x = 800
-> 0.18x = 800
-> x = 800/0.18
-> x = 444.44
Thus, the monthly budget of Edward family is $444.44.

during the first half of the year there were 54 students in the schools bicycling club. in the second half of the year the club had 68 members. find the percent of increase in club membership to the nearest whole percent
Answer:
To the nearest whole percent is 26%
Step-by-step explanation:
First half of the year = 54 students
Second half of the year = 68 members
find the percent of increase in club membership to the nearest whole percent ?
% increase in club membership = (new member - old member) / old member × 100
= (68 - 54) / 54 × 100
= 14 / 54 × 100
= 0.259 × 100
= 25.9 %
To the nearest whole percent is 26%

Ellie has been training for the Cedar Ridge Off-Road Race. The first week she trained, she ran 3 days and took the same two routes each day: 2. 5 miles on a path in the woods in the morning and a longer route at the park in the afternoon. By the end of the week, Ellie had run a total of 24 miles. Which equation can you use to find how many miles, x, Ellie ran each afternoon?
The distance that Ellie ran each afternoon is 5.5 miles for a whole week.
What is an equation?An equation is an expression that shows the relationship between two or more numbers and variables.
Let x represent the distance that Ellie ran each afternoon, since she ran 24 miles, hence:
3(2.5 + x) = 24
7.5 + 3x = 24
x = 5.5 miles
The distance that Ellie ran each afternoon is 5.5 miles for a whole week.

A house-painting company charges $350 plus $15 per hour. Another company charges $275 plus $20 per hour. Write an equation that represents when both companies will cost the same amount.
How long will the job be when both companies charge the same amount?
Answer:
350 + 15x = 275 + 20x where x = 15
Step-by-step explanation:
350 + 15x = 275 + 20x
350 - 275 = 20x - 15x
75 = 5x
75/5 = 5x/5
15 = x
350 + 15(15) = 275 + 20(15)
350+225 = 275+300
575 = 575

Answer:
We start on the number -3 on the number line. Since the b > -3 is using the greater than sign, it is an open circle and since the inequality is pointing to the right, we can draw the arrow going to the right on the number line.
Step-by-step explanation:
[tex]\dfrac{ b }{ 3 } +1 > 0[/tex]
Multiply both sides of the equation by 3. Since 3 is positive, the inequality direction remains the same.
[tex]b+3 > 0[/tex]
Subtract 3 from both sides. Anything subtracted from zero turns into a negative number.
[tex]b+3-3 > 0-3[/tex]
Simplify
[tex]b > -3[/tex]
Now we need to graph it:
Inequalities can be shown on a number line. Open circles are used for numbers that are less than or greater than (< or >). Closed circles are used for numbers that are less than or equal to and greater than or equal to (≤ or ≥).

What is slope of a line?
Slope of a line is the tangent of the angle which the line makes with the

If [tex]\theta[/tex] is the angle which the line makes with the positive direction of x axis, then slope of the line is given by
[tex]m = tan\theta[/tex]

Given f(x) = 3x-1 and g(x)=2x-3, for which value of x does g(x)=f(2)? Ox=3/2 Ox-2 Ox=5/2 Ox=4
====================================================
Work Shown:
First find f(2)
f(x) = 3x-1
f(2) = 3(2)-1 ... replace every x with 2
f(2) = 6-1
f(2) = 5
--------------
The equation g(x) = f(2) is the same as g(x) = 5 since f(2) = 5
g(x) = 2x-3
5 = 2x-3 .... replace g(x) with 5
2x-3 = 5
2x = 5+3 ... add 3 to both sides
2x = 8
x = 8/2 .... divide both sides by 2
x = 4
The value of x that satisfies the equation g(x) = f(2) is x = 4.
What is a function?A relation is a function if it has only One y-value for each x-value.
We are given two functions f(x) and g(x), and we need to find the value of x that satisfies g(x) = f(2).
We know that f(x) = 3x - 1, so f(2) = 3(2) - 1 = 5.
Therefore, we need to find the value of x that makes g(x) equal to 5.
Setting g(x) equal to 5, we get:
2x - 3 = 5
Add 3 to both sides.
2x = 8
Divide both sides by 2:
x = 4
Therefore, the value of x that satisfies the equation g(x) = f(2) is x = 4.
