Answer:

True

Step-by-step explanation: Calculate circumference from area

We are given the area, and by substitution we know that 13π = πr2. We divide out the π and are left with 13 = r2. We take the square root of r to find that r = √13. We find the circumference of the circle with the formula C = 2πr.

5. Area = 2 unit * 7 units = 14 squared units

6. Area = 3 units * 4 units = 12 square units

7 Area = Area of big rectangle + Area of small rectangle = 42 + 15 = 57 $units^{2}$

8. Area = 1 * 5 + 2*8 = 5 + 16 = 21 square units

Hope that helps!

Answer:

Step-by-step explanation:

The factors of 96 are: 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, 96

The factors of 160 are: 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 80, 160

Then the greatest common factor is 32.

Which equation shows a y- intercept of -5

Assoli18 [71]

Hi there!

»»————-　★　————-««

I believe your answer is:

Option B) $y=x-5$

»»————-　★　————-««

Here’s why:

Most options (Second, Third, and Fourth) are in slope intercept form.

⸻⸻⸻⸻

$\boxed{\text{Slope-Intercept Form}}\\\\y=mx + b\\\\\boxed{\text{Key:}}\\\\m - \text{The Slope}\\\\b- \text{The Y-Intercept}$

⸻⸻⸻⸻

We are looking for the equation where '-5' is in b's place.

⸻⸻⸻⸻

$\boxed{\text{Which equation shows a y-intercept of -5?}}\\\\---------\\\text{A}) -5y = x\\\\\text{This equation in slope-intercept form is }y=\frac{1}{5}x.\\\\\text{The 'b' part is not shown. This means that the line passes through the}\\\text{origin.}\\\\---------\\\\\text{B})\text{ }y = x-5\\\\\text{This option shows a slope of one and a y-intercept of -5.} \\\\\text{Therefore, \boxed{\text{option B is the correct answer.}}}\\\\----------\\\text{Option C has a y-intercept of 5, and Option D has a}\\$

$\text{y-intercept of 1.}$

⸻⸻⸻⸻
