Plug in the first equation(x) into another instead of x. If x equals -2y-5. Then we get 4(-2y-5)-3y=2. -8y-20-3y=2. Group like terms on different sides. -11y=22. y=22/-11. y=-2.

For what values of x is f(x) = square root of x-4 equal to 4?

zaharov [31]

Answer:

x = 20

Step-by-step explanation:

given f(x) = $\sqrt{x-4}$ , we have to solve

$\sqrt{x-4}$ = 4

Square both sides

( $\sqrt{x-4}$ )² = 4²

x - 4 = 16 ( add 4 to both sides )

x = 20

As a check

$\sqrt{20-4}$ = $\sqrt{16}$ = 4 ← correct

Find x if: - B is between A & C; -AB = x + 5; -BC = 2(x-3); and -AB ~= BC

aliya0001 [1]

Answer:

The value of x = 11

Step-by-step explanation:

Given

B is between A and C.

AB = x+5

BC = 2(x - 3)

${\overline {AB$ ≅ ${\overline {BC$

Determining the value of x

As B is between A and C, so

${\overline {AB$ ≅ ${\overline {BC$

AB = x+5

BC = 2(x - 3)

x + 5 = 2(x-3)

x+5 = 2x-6

2x-x = 5+6

x = 11

Therefore, the value of x = 11
