Find an equation of the line that goes through the points (-9,-20) and (-8,-17). Write your answer in the form y = m x + b .
Oliga [24]

Answer:

y = 3x + 7

Step-by-step explanation:

First, we will solve for the slope (m).

The formula for slope is: m = \frac{y2 - y1}{x2 - x1}

m = \frac{-17 - -20}{-8 - -9} --- enter the points into the formula

m = \frac{3}{1} --- simplify

m = 3 --- simplify

Now we will solve for the y-intercept (b).

y = mx + b

y = 3x + b --- substitute the slope into the equation

-20 = 3(-9) + b --- substitute the x and y of either point into the equation

-20 = -27 + b --- simplify

7 = b --- add 27 to both sides

b = 7

Done.

y = 3x + 7

Find the area of the shaded portion the one who answer first will get brainliest
slega [8]

Answer:

≈ 77 cm²

Step-by-step explanation:

The area of the shaded portion is calculated as

area of outer sector - area of inner sector

= (πR² - π r²) × \frac{60}{360} ( R is the outer radius, r is the inner radius )

= (π × 14² - π × 7² ) × \frac{1}{6}

= (196π - 49π ) ÷ 6

= 147π ÷ 6

≈ 77 cm² ( nearest whole number )
