Answer:

(0,-8)

Step-by-step explanation:

y-intercept is where x = 0.

That means that the y-intercept is:

(0+2)(0-4) = -8

That makes the y-intercept (0,-8)

calculate
2 ÷ 5^-2

use negative power rule x^-a = 1/x^a
2 ÷ 1/5^2

simply 5^2 to 25
2 ÷ 1/25

use this rule a ÷ b/c = a • c/b
2 • 25

simplify

Use the law of sines to find what Angle R is:
stich3 [128]

Answer:

Step-by-step explanation:

So, according to the law of Sines, we have

\frac{Sin(A)}{a} = \frac{Sin(b)}{b}

In our case, we have S and R, so...

\frac{Sin(S)}{s} = \frac{Sin(R)}{r}

And we want to isolate R...

r = sin^{-1} (\frac{Sin(S) * r}{s} ) = sin^{-1} (\frac{Sin(52) * 32}{26} ) = 75.90

the angle of R is then 75.90 degrees.

Find the approximate side length of a square game board with an<br> area of 184 in2
andrey2020 [161]

The approximate side length of a square game board with an

area of 184 in^2 is 14 inches

<h3>Area of a square</h3>

The formula for calculating the area of a square is expressed as;

A = l^2

where

l is the side length of a square

Given the following parameters

A = 184 square inches

Substitute

184 l^2

l = √184

l = 13.56

Hence the approximate side length of a square game board with an

area of 184 in^2 is 14 inches

7. point A(-2, 7); parallel to the line y = - 3x - 4
aniked [119]

Answer:

y=-3x+1

Step-by-step explanation:

plug in point into x and y, replace -4 as a +b(or any other variable to represent y intercept)

therefore,

7=-3(-2)+b

7=6+b

1=b

y=-3x+1
