Answer:

SAS

Step-by-step explanation:

We can automatically eliminate the HL answer choice, since the given triangles aren't right triangles. The only answer choices that could make sense would be ASA or SAS, but there is no ASA choice, so the answer would be SAS.

I need to find the equation of the line

deff fn [24]

Answer:

y = 3x + 3

Step-by-step explanation:

the equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

calculate m using the slope formula

m = $\frac{y_{2}-y_{1} }{x_{2}-x_{1} }$

with (x₁, y₁ ) = (- 1, 0) and (x₂, y₂ ) = (0, 3) ← 2 points on the line

m = $\frac{3-0}{0-(-1)}$ = $\frac{3}{0+1}$ = $\frac{3}{1}$ = 3

the line crosses the y- axis at (0, 3 ) ⇒ c = 3

y = 3x + 3 ← equation of line

Solve the equation. <br> 4 (6 – x) + 4 = 2 (3x + 1) - 6

PtichkaEL [24]

Answer:

x = 2.4

Step-by-step explanation:

Simplify.

24 - 4x + 4 = 6x + 2 - 6

Combine like terms (24 + 4 = 28, sorry for the confusion!)

28 - 4x = 6x - 4

Add x and add 4 to both sides.

10x = 32

x = 3.2

Answer:

a. Andrea is incorrect

b. By solving for x, we find that x does not equal 8, but it is equal to 7.

Step-by-step explanation:

8+4=2(x-1)

8+4=2x-2

12=2x-2

14=2x

x=7
