Answer:
[tex]y-1=2(x+7)[/tex]
Step-by-step explanation:
Point-slope form: [tex]y-y_1=m(x-x_1)[/tex] where a given point is [tex](x_1,y_1)[/tex] and the slope is [tex]m[/tex]
1) Find the slope of the line (m)
Slope = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex] where the given points are [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex]
Plug in the points (-7,1) and (-3,9)
[tex]= \frac{9-1}{-3-(-7)}\\= \frac{8}{-3+7}\\= \frac{8}{4}\\= 2[/tex]
Therefore, the slope of the line is 2. Plug 2 into the equation as m:
[tex]y-y_1=2(x-x_1)[/tex]
2) Plug one of the given points into the equation
We plan either plug in (-7,1) or (-3,9) and it would work either way. Below you can see the equation plugging in the point (-7,1):
[tex]y-1=2(x-(-7))\\y-1=2(x+7)[/tex]

1. A rectangle has side lengths of 3x2 + 5x - 1 and -7x+1. Which of the following expressions represents the area of the rectangle?
a. 3x²-21
b. 3x² - 35x-1
c. -21x³ - 38x²- 2x - 1
d. -21x³ - 32x² + 12x - 1
please help
21x³-42x²+12x-1
[area of rectangle =length ×breadth
=(3x2 + 5x - 1)(-7x+1)
=3x²(-7x+1)+5x(-7x+1)-1(-7x+1)
=-21x³+3x²-45x²+5x+7x-1
=-21x³-42x²+12x-1
A triangle has a base length of 14cm. The perpendicular height is 9cm. Find the area of the triangle
The area of a triangle with the given base and height is 63 cm².
Given that, a triangle has a base length of 14 cm and the perpendicular height is 9 cm.
What is the area of a triangle?The area of a triangle is defined as the total space occupied by the three sides of a triangle in a 2-dimensional plane. The basic formula for the area of a triangle is equal to half the product of its base and height, i.e., A = 1/2 × b × h.
Here, b=14 cm and h= 9 cm
So, area = 1/2 × 14 × 9
= 63 cm²
Therefore, the area of a triangle with the given base and height is 63 cm².

Kelly got a part time job and had to pay $150 worth of taxes, which was 10% of her monthly payment. How much money did she make before paying taxes?
Answer:
$1,500
Step-by-step explanation:
To find how much money she made before paying taxes, divide 150 by 0.1:
150/0.1
= 1500
So, Kelly made $1,500 before taxes
Answer:
$1,500
Step-by-step explanation:
Turn 10% into a decimal: To turn a percent into a decimal, you move the decimal twice to the left.
10%=.1
Divide: $150 divided by .1=1500
$1,500

Find the area of the parallelogram.
Answer:
36 ft^2
Step-by-step explanation:
I) Find dimensions:
The base is 9 feet, and the height is 4 feet.
(Remember, 6 ft is not the height because that is the height of the parallelogram's parallel sides.)
II) Find area:
Area = base x height
A = B x H
36 = 9 x 4
III) Find unit:
Make sure to add the unit, it is ft^2 or ft² since this figure is three-dimensional and measured in feet.
