Answer:[tex]y=-4x+14[/tex]
Step-by-step explanation:
[tex]y=mx+b\\\\y=-4x+b[/tex]
Use point (2,6) to solve for B
[tex]6=-4(2)+b\\6=-8+b\\14=b[/tex]
put b into equation
[tex]y=-4x+14[/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

The measure of an angle is 34.7°. What is the measure of its supplementary angle?
Answer:
Let the supplementary angle be x.
x+34.7°=180
or, x=180-34.7°
or, x=145.30°
:. x=145.30°
-269°

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.

Answer:
640 units squared
Step-by-step explanation:
First, the formula of a trapezoid is (a + b) x 2 divided by h
So, 40 + 24 = 64
64 x 20 = 1280
and 1280/2 = 640

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.

McKenzie delivers coupons to her neighborhood. This week she has 553 coupons to deliver. If she wants to give 7 coupons to each neighbor, which equation can be used to find the number of neighbors, n, to whom McKenzie can give coupons?
Answer:
Number of neighbors to whom McKenzie can give coupons = 79
Step-by-step explanation:
Coupons to deliver this week = 553
Coupons delivered to each neighbor = 7
which equation can be used to find the number of neighbors, n, to whom McKenzie can give coupons?
Let
n = number of neighbors to whom McKenzie can give coupons
n = Coupons to deliver this week / Coupons delivered to each neighbor
= 553 / 7
= 79
n = 79 neighbors
Number of neighbors to whom McKenzie can give coupons = 79
