Answer:
y = 2/3x + 2
Step-by-step explanation:
Slope intercept form is y=mx+b where m is the slope and b is the y intercept.
Given 2 points you can find the slope using (y-y1)/(x-x1)
m = (-2-4)/(-6-3) = -6/-9 = 2/3
To find b use one of the points and m and plug into the slope intercept form and then solve for b.
y=mx+b
4=2/3(3) + b
4=2 + b
b=2
Now we can write the final equation as : (plug m and b back in)
y = 2/3x + 2
To write in slope-intercept form, we must first find the slope.
[tex]Slope = \frac{y2-y1}{x2-x1} =\frac{4-(-2)}{3-(-6)} =\frac{6}{9}=\frac{2}{3}[/tex]
Now lets put into the point-slope form which requires the use of any one of the two points given which in this case can be (3,4) and the slope 2/3
[tex]y - y_{0} =m(x-x_{0} )\\y-4=\frac{2}{3} (x-3)\\[/tex]
Now to put into the slope-intercept form, we must solve for y:
[tex]y - 4 = \frac{2}{3} x -2\\y = \frac{2}{3} x +2[/tex]

Step-by-step explanation:
if h(x) = x^2-5x+7 find each value
1/3*h(-8)
if h(x) = [tex]x^{2} -5x+7[/tex] so the value of [tex]\frac{1}{3}[/tex]× [tex]h(-8)[/tex] = [tex]\frac{111}{3}[/tex].
A mathematical equation is a formula that uses the equals sign to represent the equality of two expressions. The meanings of the word equation and its cognates in other languages can vary slightly. For instance, in French, an equation is defined as having one or more variables, whereas, in English, an equation is any well-formed formula that consists of two expressions linked by the equals sign.
Finding the values of the variables that result in equality is the first step in solving an equation with variables. The variables that must be included in the equation are also known as the unknown.
we have h(x) = [tex]x^{2} -5x+7[/tex]
So, substitute the value [tex]x=-8[/tex] in the equation,
h([tex]-8[/tex]) = [tex](-8)^{2} -5(-8)+7[/tex]
= [tex]64+40+7[/tex]
= [tex]111[/tex]
And now we shall multiply it with [tex]\frac{1}{3}[/tex],
we get, [tex]\frac{1}{3}[/tex]× [tex]h(-8)[/tex] = [tex]\frac{111}{3}[/tex]

Answer:
c. maximum at (-1,-4)
Step-by-step explanation:
just took a quiz
The graph has its maximum at (-1, -4).
y=-(x+1)^2-4
Maximum of the equation is to determine.
A cross section of the cone and represented by an equation y=4ax^2.
Here,
y=-(x+1)^2-4
While plotting the curve, the curve is maximum at (-1, -4) beside this point curve is decreasing.
Thus , the graph has its maximum at (-1, -4).

A package of 5 pairs of insulated gloves costs $43.95. What is the unit price of the pairs of gloves?
Answer:
5.89 dollars
Step-by-step explanation:
To find the unit price, we use t/q where t is the total price and q is the quantity.
Therefore, it costs 5.89 dollars for a pair of gloves.
The unit price of the pair of gloves will be $8.79 for each pair of gloves.
What is the rate?The rate is the ratio of the amount of something to the unit. For example - If the speed of the car is 20 km/h it means the car travels 20 km in one hour.
The definition of simplicity is making something simpler to achieve or grasp while also making it a little less difficult.
A package of 5 pairs of insulated gloves costs $43.95. Then the unit price of the pairs of gloves is calculated as,
Rate = $43.95 / 5
Rate = $8.79 for each pair of gloves
The unit price of the pair of gloves will be $8.79 for each pair of gloves.

On Monday, Jolene played basketball and made 75% of the shots she took. If she missed 7 shots, how many shots did she take? Show your work.
Answer:
She took 28 shots, 7 shots would be the remaining 25% so you multiply it by 4 to get 100% or 7 × 4 = 28
missed shots = 7 = 25% since 75% are successful
proportionality table
25% ...............7
100% ........... = 7 x 100% : 25% = 28
total = 28 shots

Find the sales tax. Then find the total cost of the item.
Sales Tax
Selling Price $40.00 Rate of Sales Tax 3% Sales Tax ?
Answer:
tax: $1.20total cost: $41.20Step-by-step explanation:
The sales tax is found by multiplying the tax rate by the item price. The total cost will be the sum of the item price and the tax.
__
tax = 0.03 × $40 = $1.20
total cost = selling price + tax = $40 +1.20 = $41.20
If 2 pints = 1 quart, how many pints are in a 26-quart container
Answer:
52 pints
Step-by-step explanation:
Given;
2 pints = 1 quart
To Find;
How many pints are in a 26-quart container
Solve;
Since 2 pints = 1 quart
Then the Formula = divide the volume value by 2
The equation for 2 pints = 1 quart is 2 ÷ x = 1
which x = 2.
Thus, the equation for 26 quart container = how many pints =
x ÷ 2 = 26
Divide/Multiply sides by 2
2x/2 = 26 * 2
Simplify
x = 52
Hence, there are 52 pints in a 26 quart container

[tex]f(x)=2^x\\\\g(x)=x-4\\\\(f\circ g)(x)=f(g(x))=f(x-4)=2^{x-4}[/tex]
This means that the parent function, [tex]f(x)=2^x[/tex], will shift 4 units to the right along the x-axis, so this DOES NOT affect the range (nor the domain either). Thus, [tex]y > 0[/tex] would be the range.

Find the area
Answer:
240 square feet
Step-by-step explanation:
The area of a composite figure can be found by adding the areas of its parts.
__
Extending the vertical line across the figure cuts off a rectangle on the left that is 18 ft long and 10 ft high. It cuts off a triangle on the right that has a base of 20 ft and a height of 24-18 = 6 ft.
The sum of the areas of these parts is ...
rectangle area + triangle area
= (10 ft)(18 ft) +1/2(20 ft)(6 ft) = 180 ft² +60 ft²
= 240 ft² . . . . area of the figure
_____
Additional comment
You can see that this is the product of the height of the rectangle and the overall length of the figure. This means the smaller triangles that stick above or below the horizontal lines would fit exactly into the spaces at the tip of the arrow, filling in a 10 ft × 24 ft rectangle.

-½n² + 18 =0
n= ____
Answer: n=6
Step-by-step explanation:
First you subtract 18 from both sides so that it become -1/2n^2=-18
Second divide both sides by -1/2 so it becomes -18/(-1/2)=n^2
Then you simplify and get n^2=36
Finally you find the square root of both side, and you get n=6
