Answer:
4.2×10to the 6th or 4,200,000
Step-by-step explanation:
First you have to know that you are multiplying these two numbers. When you multiply exponents like there you add the matissa's (6&7) and add the exponents.
6×10to the 2 * 7×10to the 3rd
42 × 10to the 2+3
42×10to the 5th
Something else you need to know is your matissa cant be higher than 10
So:
4.2 × 10to the 6th is your answer
Answer: each child gets 3 cups
Step-by-step explanation:
Answer:
f-1(x) = (x-8)/2
Step-by-step explanation:
f(x) = 2x+ 8
y = 2x + 8
replacing y and x
x = 2y + 8
2y = x- 8
y =( x-8)/2
f-1 (x) =( x-8)/2
Answer:
The inverse is 1/4x
Step-by-step explanation:
y = 4x
To find the inverse, exchange x and y
x = 4y
Solve for y
1/4 x = 4y/4
1/4x = y
The inverse is 1/4x = y
