Answer:

y = -2x + 3

Step-by-step explanation:

Let's just put the three points together.

(-1, 5) (-4, 11) (-7, 17)

First, let's find the slope with y2 - y1/x2 - x1

Plug in using (-1, 5) and (-4, 11)

11 - 5/-4 + 1 = 6/-3 (simplify)

-2 is the slope

Now plug in (-7, 17) in the equation to get b or the y-intercept)

y = mx + b

17 = -2(-7) + b

17 = 14 + b (subtract 14 on both sides)

3 = b

y = -2x + 3

Describe the relationship between the area of a circle and its circumstances

valentina_108 [34]

Answer:

$A = \frac{r}{2}C$

Step-by-step explanation:

Given

Shape: Circle

Required

The area and the circumference (relationship)

This implies that, we write an expression that relates the area and the circumference.

Circumference is calculated as:

$C = 2\pi r$

Area is calculated as:

$A = \pi r^2$

The area can be rewritten as:

$A = \frac{2\pi r^2}{2}$

Further rewrite as:

$A = \frac{r}{2}*2\pi r$

Recall that: $C = 2\pi r$

So, the expression becomes

$A = \frac{r}{2}*C$

$A = \frac{r}{2}C$

Which value or in the solution set of the inequality − 2/3 x + 13 ≥ − 1

Svetach [21]

Answer:

x $\leq$ 21

Step-by-step explanation:

(-2/3)x+13≥ -1

(-2/3)x≥ -14 (I subtracted by 13 on both sides)

x $\leq$ -14*(-3/2) (I divided by -2/3 on both sides)

x $\leq$ 21
