Answer:

x = -9

Step-by-step explanation:

-5 = \frac{x}{3} - 2

add 2 to both sides:

\frac{x}{3} = -3

multiply both sides by 3:

x = -9

For the linear equation, find the product of 5 and the linear equation, and solve both equations for y. 2x + 7y = 11
tensa zangetsu [6.8K]

Answer:

(a) 10x + 35y = 55

(b) y = \frac{11 - 2x}{7}

Step-by-step explanation:

Given

2x + 7y = 11

Solving (a): Multiply equation by 5.

Multiply both sides by 5

5 * (2x + 7y) = 11*5

Open bracket

5 * 2x + 5 * 7y = 11*5

10x + 35y = 55

(b) Solve for y in 10x + 35y = 55 and 2x + 7y = 11

10x + 35y = 55

Subtract 10x from both sides

35y = 55 - 10x

Divide both sides by 35

\frac{35y}{35} = \frac{55 - 10x}{35}

y = \frac{55 - 10x}{35}

Factorize the numerator:

y = \frac{5(11 - 2x)}{35}

Express 35 as 7 * 5

y = \frac{5(11 - 2x)}{7 * 5}

y = \frac{(11 - 2x)}{7}

y = \frac{11 - 2x}{7}

<em>When </em>2x + 7y = 11<em> is solved, the solution will be: </em>y = \frac{11 - 2x}{7}<em></em>

Find the domain of f(x) = -4x + 2 for the range {-5, 2, 6, 18).
Flauer [41]

Answer:

Step-by-step explanation:

calculate x for this equation

f(x) = -5 : -4x +2 = - 5 so : -4x =-7        x = 7/4

f(x) = 2  : -4x +2 = 2   so : -4x =0        x = 0

f(x) =6  : -4x +2 = 6  so : -4x =4       x = -1

f(x) = 18  : -4x +2 = 18  so : -4x =16        x = - 4

the domain is : D = {7/4, 0, -1, -4}
