Alrighty lets see if I can explain this.
The formula is y=mx+b. We already have m, 0.4, which is the slope of the line, and we have b, 4, which is the y-intercept. If you plug in the given value of x, your formula ends up being y=0.4(14)+4 and when we graph that, your end with a straight line across the graph horizontally. If you solve the formula, your answer is y= 9.6
The slope of any horizontal line is 0, as it remains constant.

Solve the system of equations.<br> 7x+10y=36<br> y=2x+9<br><br> x = ______<br><br> y = ______
wel

Step-by-step explanation:

Substitute the y in the 1st equation with the 2nd equation.

7x + 10(2x + 9) = 36

7x + 20x + 90 = 36

27x + 90 = 36

3x + 10 = 4

3x = -6

x = -2

So now we can find y.

y = 2x + 9 = 2(-2) + 9 = (-4) + 9 = 5.

So x = -2, y = 5.

The perimeter of a square is represented by the expression 32x - 12.8 find the side length of the square.
djverab [1.8K]

Given:

Perimeter of a square = 32x-12.8

To find:

The side length of the square.

Solution:

We know that, the perimeter of the square is 4 times of its side length.

P=4a

Where, a is the side length.

Perimeter of a square = 32x-12.8

Now,

4a=32x-12.8

Divide both sides by 4.

a=\dfrac{32x-12.8}{4}

a=\dfrac{32x}{4}-\dfrac{12.8}{4}

a=8x-3.2

Therefore, the side length of the square is 8x-3.2 units.
