Your forgot the remainder points and the graph.

Coordinates: (-4, 4) / (-1, 3) / (2, 2)

Slope: 3

Slope Intercept Form: y = 3x - 7

Hope This Helps :)

What is the area?? Please help

Olegator [25]

Answer:

<h3>324 ft²</h3>

Step-by-step explanation:

We have the triangle and the rectangle.

The formula of an area of a triangle:

$A_{\triangle}=\dfrac{1}{2}bh$

b - base

h - height

The formula of an area of a rectangle:

$A_{\boxed{\ }}=lw$

l - length

w - width

We have b = 24 ft, h = 7 ft, l = 24 ft and w = 10 ft.

Substitute:

$A_\triangle=\dfrac{1}{2}(24)(7)=(12)(7)=84\ ft^2$

$A_{\boxed{\ }}=(24)(10)=240\ ft^2$

The area of the figure:

$A=A_{\triangle}+A_{\boxed{\ }}$

Substitute:

$A=84+240=324\ ft^2$

Which of the following are solutions to the equation below? Check all that apply. 4x2 - 12x + 9 = 5

Anika [276]

Step-by-step explanation:

4x² - 12x + 9 = 5 → 4x² - 12x + 4 = 0 → x² - 3x + 1 = 0

∆ = b² - 4ac → ∆ = (-3)² -4(1)(1) = 9 - 4 = 5

x = (-(-3) ± √5)/2(1) = (3 ± √5)/2

x² - 3x + 1 = 0 → (x - 3/2)² - 9/4 + 1 = 0 → (x - 3/2)² = 5/4 → x - 3/2 = ±√5 / 2 → x = ½( 3 ± √5)
