Answer:
6
Step-by-step explanation:
Let x = number of hours.
Let y = cost.
The fixed cost is $11.
The cost per hour is $2.
For x hours, the cost per hour is 2x.
y = 2x + 11
23 = 2x + 11
12 = 2x
x = 6

Answer:
Step-by-step explanation:
I multiplied every coordinate by 1/3
The coordinates are in the attachment below
A) Maple Street is 95ft.
Elm Street is 189 ft.
here are the equations if u need them
lets' say elm st=E, Main st= M and Maple st.=A
E= 2A-1
A=M/2-8
M=206ft.
Since knowing that M=206 u would do 206/2=103 subtracting 8 which is 95 and then inputting 95 in the first equation and getting 190 minus 1 which is 189 and that's how u solve this problem.
Answer:
C.
Step-by-step explanation:
When we have an expression where the a number with an exponent is raised to another power, we simply apply one of the laws of exponents known as the power rule.
The rule says we just simply multiply the exponents together.
Thus, ![(a^m)^n = a^{m*n} = a^{mn}](https://tex.z-dn.net/?f=%20%28a%5Em%29%5En%20%3D%20a%5E%7Bm%2An%7D%20%3D%20a%5E%7Bmn%7D%20)
Therefore, the expression given, where we need to apply this rule is: ![(6^{10})^{-7} = 6^{10*-7} = 6^{-70}](https://tex.z-dn.net/?f=%20%20%286%5E%7B10%7D%29%5E%7B-7%7D%20%3D%206%5E%7B10%2A-7%7D%20%3D%206%5E%7B-70%7D%20%20)
The answer is C. ![(6^{10})^{-7}](https://tex.z-dn.net/?f=%20%286%5E%7B10%7D%29%5E%7B-7%7D%20)
