Answer:
D
Step-by-step explanation:
the center is (0,8)
(to solve this just flip the signs on the constants being added to x and y (there is an invisible constant of 0 being added to the x))
the radius is 7 (or √49)
Answer:
<u>The correct answer is D. 114</u>
Step-by-step explanation:
There are 252 students of twelfth grade at Vista View High School.
99 walked to school
11 went by bicycle
28 used the school bus
To find the amount of twelfth graders that rode in a car, we do this calculation:
Amount of twelfth graders that rode in a car = Total of twelfth graders - those who walked - those who went by bicycle - those who used the bus
Replacing with the real values, we have:
Amount of twelfth graders that rode in a car = 252 - 99 - 11 - 28 = 252 - 138 = 114
<u>The correct answer is D. 114</u>
Answer:
nice question...
so here we go
3^ -x = 1 / 3^x
so 1/ 3^x = 2 so 3^x = 1/2
we can write 3^2x as 3^x multiplied by 3^x right?..(law of exponents)
recall that 3^x =1/2
so now according to question we have to find the value of 3^2x = 1/2 * 1/2 = 1/4
Step-by-step explanation:
5. 2*(7+x) which if you distributed would be 14+2x.
6.x - 8^2 or x-64.
Hope this helped!
Answer:
-4
Step-by-step explanation:
7x^3 + 5x^2 - 2
= 7*-1 + 5*1 - 2
= -7 + 5 - 2
= -4
