Answer:

the first answer is a⁴ +am²

Step-by-step explanation:

when dividing exponents add or subtract each other

a² + a² = a⁴

am + am =am ² ( they each have one so they add up to two)

an and mn cancel each other out

Cory has only dimes in his piggy bank. A dime is worth 10 cents. Which could be the value of the money in Cory's piggy bank?
Sergeeva-Olga [200]

Answer:

It depends on how many dimes are in the piggy bank. It could be any answer that didn't have a 5 in the tenths place. For example, it couldn't be a number like $1.05 because any whole number multiplied by 10 would end in a 0

WHOEVER EXPLAINS ALL THEIR WORK AND GOES THROW EAXH STEP WILL GET BRAINLEST THAT IS COMPLETELY FINISEHD. write the equation of t
neonofarm [45]

Answer:

y = -3x+11

Step-by-step explanation:

I accept your challenge!

First we know that a equation of the line is a linear equation, and its equation is:

y = mx+b

m: \text{slope}\\b: \text{y-intercept}

In this context, the slope, defined as the steepness of a line is characterized as the ratio of RISE (the difference in the y-coordinates, the vertical change) over the RUN (the difference in x-coordinates, the horizontal change).

$m=\frac{\text{change in y}}{\text{change in x}}=\frac{\Delta y}{\Delta x}=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}   $

Once we know two points where the line goes through, we can get the slope, once we know the change in y and x.

I will take (3,2) as Point 1 and (4,-1) as Point 2.

So, x_{1}=3 \text{ and } y_{1}=2\\x_{2}=4 \text{ and } y_{2}=-1

$m=\frac{\text{change in y}}{\text{change in x}}=\frac{\Delta y}{\Delta x}=\frac{-1-2}{4-3}   $

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

Now we have to find the y-intercept:

To do so, think about the the points given and the nearly finished equation, we can find b with those two informations.

Our currently equation of the line is:

y = -3x+b

Using the points, take Point 1 as an example, it says that when x = 3, y = 2, so plugging it in the equation:

2 = -3(3)+b\\2 = -9+b\\11 = b

Taking the Point 2

-1 = -3(4)+b\\-1 = -12+b\\11 = b

Now we found b! The equation is complete!

y = -3x+11

What must be the value of x so that lines a and b are parallel lines cut by transversal f?
ExtremeBDS [4]

we know that

if the lines a and b are parallel lines cut by transversal f

then

(6x-36)=96 --------> by alternate exterior angles

solve for x

(6x-36)=96\\ 6x=96+36\\6x=132\\x=(132/6)\\x=22\ degrees

therefore

<u>the answer is</u>

the value of x is 22\ degrees
