Answer:

The solution of the system of equation are (10,15).

Step-by-step explanation:

The given two linear two variable equations are

- x - 2y = - 40 ........ (1) and

x + 4y = 70 .......... (2)

Now,adding thoes two equations (1) and (2) we get,

- 2y + 4y = - 40 + 70

⇒ 2y = 30

⇒ y = 15.

Now, putting y = 15 in the equation (2), we get,

x = 70 - 4y = 70 - 4(15) = 10

Therefore, the solution of the system of equation are (10,15). (Answer)

Answer: (C) divide by 1

<u>Step-by-step explanation:</u>

when dividing by x - 1, set the expression equal to zero to find the zero. That is actually what you are dividing by:

x - 1 = 0 ⇒ x = 1

so the number outside of the synthetic division symbol is 1.

Find the slope of the line (-3,-2) (1,6)

nlexa [21]

Answer:

slope = 2

Step-by-step explanation:

Calculate the slope m using the slope formula

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

with (x₁, y₁ ) = (- 3, - 2) and (x₂, y₂ ) = (1, 6)

m = $\frac{6-(-2)}{1-(-3)}$ = $\frac{6+2}{1+3}$ = $\frac{8}{4}$ = 2
