-2 from both sides
5x=-5
x= -1

Answer:

$x=-1$

Step-by-step explanation:

1) Subtract 9x from both sides.

$14x+2-9x=-3$

2) Simplify 14x+2-9x to 5x+2.

$5x+2=-3$

3) Subtract 2 from both sides.

$5x=-3-2$

4) Simplify -3-2 to -5.

$5x=-5$

5) Divide both sides by 5.

$x=-1$

Therefor, the answer is x = -1

for an art project you make a square print with a side length of 8 inches. You make a frame using strip of wood 1 1/4 inch wide.

lord [1]

Given that square print has side length = 8 inches

Given that you make a frame using strip of wood 1 1/4 inch wide. Since frame is on both sides of the square print so new side length after adding the frame = $1 \frac{1}{4} + 8 + 1 \frac{1}{4} = 10 + \frac{2}{4} = 10 + \frac{1}{2} = 10.5$ inches

Area of the square is given by formula $= x^2$ where x is the side of square

Shape of the frame including print will also be square so

Area of the frame including print $= 10.5^2 = 110.25$ square inches

Area of the print = $8^2 = 64$ square inches

We have to find the area of frame only so we can subtract area of print from the total area

Area of frame = [Area of frame including print] - [Area of print]

Area of frame = 110.25-64 = 46.25

Hence final answer is 46.25 square inches

Please help solve: Graph y-4=2(x-2)

xeze [42]

Answer:

Graph y = 2x

Step-by-step explanation:

First, let's get the equation into standard form. Distribute the 2 on the right.

$y-4=2x-4$

Next, we want the variable "y" to be alone, so we at 4 to both sides.

$y-4+(4)=2x-4+(4)\\\\y=2x$

That is our equation in standard y = mx + b form. "m" is our slope, while "b" is our y-intercept. Above , we don't have a value for b, therefore the line passes through the origin.

We do, however, have a slope, which can be thought of as $\frac{rise}{run}$ or rise over run. To represent this, we can rewrite our slope as:

$y=\frac{2}{1}x$

Meaning in each interval, the line goes up by 2 units, and moves forward by 1.
