Answer:
x = 4
Step-by-step explanation:
y = - 2 is the equation of a horizontal line parallel to the x- axis.
A perpendicular line is therefore a vertical line parallel to the y- axis with equation
x = c
where c is the value of the x- coordinates the line passes through.
The line passes through (4, - 2 ) with x- coordinate 4 , thus
x = 4 ← equation of perpendicular line
A: for every foot you will divide by 9 feet.
B: divide 15 by 9
Answer:
Option C is correct.
Step-by-step explanation:
We are given the expression:

The value of a =5 and k = -2
Putting the values and solving

Option C is correct.
Answer:
The value is 2401
Step-by-step explanation:
First we need to understand what's means 7 to the 4th power, or 7^4.
7 is the power base, the power base is the number that we are going to repeat the number of times the exponent says.
4 is the exponent, which will tell us how many times to multiply 7.
So , then we would have
1) 7 x 7 x 7 x 7
2) 49 x 7 x 7
3) 343 x 7
4) finally 2401
The answer would be C and E
