Find the areas of the<br> trapezoids.

Elza [17]

Answer:

A = 3(½(1 + 4)) = 7.5 units²

Step-by-step explanation:

area of a trapezoid is the average of the bases times the height.

h = -1 - (-4) = 3

base1 TR = 0 - (-1) = 1

base2 PA = 2 - (-2)) = 4

Find slope for 7x-2y=0.2<br><img src="https://tex.z-dn.net/?f=7x%20-%202y%20%3D%200.2" id="TexFormula1" title="7x - 2y = 0.2" al

Answer:

slope = -7/2

Step-by-step explanation:

To find the slope, we will solve the equation for y.

7x-2y=0.2

Subtract 7x from each side.

7x-7x-2y=-7x+0.2

-2y = -7x+0.2

Then we need to divide each side by -2

-2y/-2 = -7x/-2 + 0.2/-2

y = -7/2 x -0.1

This is in the form y= mx+b where m is the slope and b is the y intercept.

So the slope is -7/2 and the y intercept is -0.1

Enter the given equation in exponential format. log4/5 20x=12y

bekas [8.4K]

Answer: $\bold{(20x)^{\frac{1}{12}}=(\frac{4}{5})^y}$

<u>Step-by-step explanation:</u>

$log_{\frac{4}{5}}(20x)=12y\\\\\text{divide 12 from both sides:}\quad \frac{1}{12}log_{\frac{4}{5}}(20x)=y\\\\\text{condense log (coefficient converts to exponent):}\quad log_{\frac{4}{5}}(20x)^{\frac{1}{12}}=y\\\\\text{use log rules to convert log to exponential form:}\quad (20x)^{\frac{1}{12}}=(\frac{4}{5})^y$
