Answer: 2^5

Step-by-step explanation: Diego should have added the exponents instead of multiplying them. I know it sounds weird but because both of the numbers are 2's you are able to combine them. When multiplying them together you should keep the base the same and add the exponents. In this case, 2^2 x 2^3 would be 2^5. Hope this helps.

Answers

Answer:

a. 40%

b. 8%

c. 135%

Step-by-step explanation:

4 dimes is 40 cents out of 100 cents, so that's 40%. 1 nickel is 5 cents and 3 pennies are 3 cents, which adds up to 8 cents out of 100 potential cents, so 8%. 5 quarters is 1.25 dollars and a dime is 10 cents, together it makes 1.35 dollars. Multiply that by 100 since there are 100 cents in a dollar and you get 135%

Can someone help me with my math work

Answers

Answer:

Step-by-step explanation:

So its difficult to show

Y= X-6 so what ever x is, y is six less than that so

X= -4 Y= -10

X= 0 Y=-4

X=4 Y=0

X=8 Y= 4

Then plot these on a graph like co-ordinates (x,y) and draw a straight line through them

Y= 4/3x -2 so whatever x is y is 4/3 and 2 less then that

X=-4 Y= -5

X=0 Y= -2

X=4 Y=1

X= 8 Y= 4

Then plot these on a graph like co-ordinates (x,y) and draw a straight line through them

Y= -2

Find minus 2 on the y axis and draw a horizontal line through it all the way across the grid.

Y= 2+ 1/4x  so whatever x is y is 1/4 of x add 2

X=-8 Y= 0

X= -4  Y = 1

X=0 Y=2

X=4 Y=3

X=8 Y=4

Then plot these on a graph like co-ordinates (x,y) and draw a straight line through them

Do this method for 9

y = 2x -3 so whatever x is, y is  2 times that -3

y=2x +1 so whatever x is y is 2 times that +1

y= 2x so whatever x is y is 2 times that

Then plot the answers on a graph like co-ordinates (x,y) and draw a straight line through them

Make sure to label each line

Hope this helps

you just have to see where the x is & count up or down in till you get to your number
