Graph y = 4x - 1. When x = -2, what is the ordered pair of the solution?

Alenkinab [10]

(-9, -1)

(-9,-1) . -1 because that is the y intercept from the equation.

-9 because when you substitute -2 for x, and multiply by 4, you get -8. Then you subtract one, making the x value -9.

Therefore, the ordered pair of the solution is (-9,-1)

Hope this helps, please consider marking branliest if it did.

Why is the value of q?

Rudiy27

Given:

QSR is a right triangle.

QT = 10

TR = 4

To find:

The value of q.

Solution:

Hypotenuse of QSR = QT + TR

= 10 + 4

= 14

Geometric mean of similar right triangle formula:

$\frac{\text { hypotenuse }}{\text { leg }}=\frac{\text { leg }}{\text { part }}$

$$\Rightarrow \frac{14}{q} =\frac{q}{4}$

Do cross multiplication.

$$\Rightarrow14\times 4 =q\times q$

$$\Rightarrow 56 =q^2$

Switch the sides.

$$\Rightarrow q^2 =56$

Taking square root on both sides.

$\Rightarrow q =2 \sqrt{14}$

The value of q is $2 \sqrt{14}$ .
