Answer:

y = 2x - 8

Step-by-step explanation:

Point(2 , -4) ; slope = 2

Point- slope form:

y - y1 = m(x - x1)

y - [-4] = 2(x - 2)

y + 4 = 2x - 2*2

y + 4 = 2x - 4

y= 2x - 4 - 4

y = 2x - 8

Answer:

The correct option which best describes this method is:

Find half of 24 to calculate the radius. Then square the radius and multiply the result by $\pi$

Option D is correct option.

Step-by-step explanation:

The circumference of table top = 24 $\pi$ inches

We need to find area of table top

The formula used to find area is: $Area = \pi r^2$

We need to find radius of tabletop.

The formula used to find circumference is: $Circumference = 2\pi r$

Putting value of circumference we can find radius

$Circumference = 2\pi r\\24\pi =2\pi r\\r=\frac{24\pi}{2\pi}\\r=12$

So, radius of table top = 12

Now, finding the area:

$Area = \pi r^2\\Area=\pi(12)^2\\Area=3.14(144)\\Area=452.16\:inches^2$

So, the correct option which best describes this method is:

Find half of 24 to calculate the radius. Then square the radius and multiply the result by $\pi$

Option D is correct option.

Alright so your budget is 154 so that already means you cant spend more than
$154. So the uniform is $12 so the inequality could start as:
154 is less than or equal to 12 plus the number of karate classes, which would be;
154 ≤ 12 + 8c
so the answer is B
B. 154 ≤ 12 + 8c
If I helped please mark as brainliest thanks.

HELP PLEASE Complete the table given one rule Rule: y=4x

I am Lyosha [343]

The rule is that y equals 4 times x.

Whatever value of x you have, multiply it by 4 to find the corresponding y value.

If x = 3, y = 4 * 3 = 12

If x = 4, y = 4 * 4 = 16

If x = 5, y = 4 * 5 = 20

The table looks like this:

x y
