Answer:

I think it is x^2 = 0

Step-by-step explanation:

because -1^2 =1 also with 1^2

you can't get a - 16 because a negative changes to a positive when squared

and nothing squared equals 12

I need to find the slope and b Y=mx+b HELP ME

Naddika [18.5K]

Answer:

$y=-\frac{4}{3}x+20$

Step-by-step explanation:

stupid enough

y=mx+b

$\frac{y1-y2}{x1-x2}$

slope = 16-12/3-6

-4/3

$y=-\frac{4}{3}x+b$

plug in x and y

16=-4/3(3)+b

b=20

SOMEONE PLS HELP ME WITH THIS

jolli1 [7]

Answer:

x = 11.25

Step-by-step explanation:

-6 = 0.8x - 15

Add 15 to both sides;

-6 + 15 = 0.8x - 15 + 15

9 = 0.8x

Divide both sides by 0.8;

x = 11.25

Is (-4, 2) a solution of 4x + 5y < -7?

cupoosta [38]

Answer:

Step-by-step explanation:

Substitute the coordinates of the point into the left side of the inequality, evaluate and compare.

4(- 4) + 5(2) = - 16 + 10 = - 6 > - 7

Thus (- 4, 2 ) is not a solution

Corbin is selling cheese at the farmers’ market. One wheel of cheese has a diameter of 11 inches.

sveticcg [70]

Answer:

I. 94.99 in²

II. $0.23

Step-by-step explanation:

Given the following data;

Diameter of wheel = 11 inches

$\pi = 3.14$

Cost of wheel = $21.35

$Radius, r = \frac {diameter}{2}$

$Radius, r = \frac {11}{2} = 5.5 \; inches$

Part A

To find the area;

We know that a wheel is circular in nature. Thus, the area of a circle is given by the formula;

$Area, A = \pi r^{2}$

Substituting into the equation, we have;

$Area, A = 3.14 * 5.5^{2}$

$Area, A = 3.14*30.25$

Area, A = 94.99 in²

Part B

To find cost per square inch;

$Cost \; per \; square \; inch = \frac {Cost \; per \; wheel}{Area \; of \; wheel}$

$Cost \; per \; square \; inch = \frac {21.35}{94.99}$

Cost per square inch = $0.23
