Answer all 5 for the points please, don't need an explanation just the answers, brainliest to the first person to answer all 5.

Step-by-step explanation:

in the form y = mx + b m is the slope and y is the y intercept. Rewrite each problem to solve.

11) y = 7x - 5

-5 is the y intercept

12) y = -x + 9

9 is the y intercept

13) 4y - 8 = 2x

4y = 2x + 8

y = (2x + 8)/4

y = 1/2x + 2

2 is the y intercept

14) 11x - 8y = - 48

-8y = -11x - 48

y = (-11x - 48)/-8

y = 11/8x + 6

6 is the y intercept

15) x - 3y = 8

-3y = 8 - x

y = (8 - x)/-3

y = -3/8 + 1/3x

y = 1/3x - 3/8

-3/8 is the y intercept

answer is 8x+24

area of vanessa's patio = length × width

given, length = (3x² + 5x + 10)

width = (x² - 3x - 1)

area of vanessa's patio = (3x² + 5x + 10)(x² - 3x - 1)

= 3x²(x² - 3x - 1) + 5x(x² - 3x - 1) + 10(x² - 3x - 1)

= 3x⁴ - 9x³ - 3x² + 5x³ - 15x² - 5x + 10x² - 30x - 10

= 3x⁴ - 4x³ - 8x² - 35x - 10

hence, expression of vanessa's patio = (3x⁴ - 4x³ - 8x² - 35x - 10)

8
