Answer:
A) 9^7
Step-by-step explanation:
For this type of problem, since they both have the same base, you can add the exponents together and have the base remain the same. So you would have 5+2 = 7.
is is 169.47058823 yes this the anser
L=7+W
area=30=LW
so subsitute 7+W for length
30=(7+W)(W)
30=W²+7W
minus 30 both sides
0=W²+7W-30
factor
what 2 numbers multiply to get -30 and add to get 7
-3 and 10
0=(W-3)(W+10)
set to zero
0=W-3
3=W
0=W+10
-10=W
false, can't have a negative width
width=3in
L=7+W
L=7+3
L=10
the length is 10in
the width is 3in
The 24 oz. is the better deal. For the 24 oz, each ounce is worth $.08 compared to $.10 per ounce for the 32 ounce bottle.
Answer:
The graph of y=-3x^n is the reflection of the graph of y=3x^n about the x axis.
Step-by-step explanation:
If you graph these two functions, then you will notice that they look similar. for example the points of (1,-3) on graph y=-3x^n and point (-1,-3) on graph y=3x^n. They have the same y value but just the reflection of the x value. I hope this helped !!
