Answer:

$y-3=-3(x+5)$ or $y=-3x-12$

Step-by-step explanation:

There is enough info to make a point slope equation.

Formula: $y-y_1=m(x-x_1)$

Plug in the formula:

$m = -3\\(x_1,y_1) = (-5, 3)$

$y-3=-3(x+5)$

Convert into Slope Intercept Form: $y=mx+b$

AngleB = Round your answer to the nearest hundredth. А 5 ? B С 4.

Zarrin [17]

Answer:

$B=36.87$

Step-by-step explanation:

As we are given the adjacent (a) side and the hypotenuse (h), we can use the cosine function to find the measure of angle B.

Recall that $cos(B)=\frac{a}{h}$

This means that in order to find B, we need to take the inverse of cosine

This gives us

$B=cos^{-1} (\frac{4}{5} )$

From a calculator, we find that the answer of this is

$B=36.869$

When this is rounded to the nearest hundredth, we get

$B=36.87$

Convert the following percent to a decimal and then to a common factor 87.5%

Alexus [3.1K]

First to convert the percent to a decimal divide by 100 or move the decal point twice to the left.

87.5% -> 0.875

You can convert to a fraction by placing the expression over 100 and simplify, this will equate to 7/80
