Please write that x^2 + y^2 = 7^2. The " ^ " indicates exponentiation.
This is the equation of a circle with center at the origin and radius 7.
Supposing that you translate this circle's center to point (h,k). The equation is then
(x-h)^2 + (y-k)^2 = 7^2. The new center is (h,k) = (-3, 2). Substitute -3 for h and 2 for k in the above equation.
Simplify your result and you'll then be done!
Answer:
B -2
Step-by-step explanation:
y = kx where k is the constant of variation
We have -4y = 8x
Divide each side by -4
-4y/-4 = 8x/-4
y = -2x
The constant of variation is -2
Answer:
108 blocks.
Step-by-step explanation:
Joe's grandmother lives 36 blocks away from Joe.
Joe rode two thirds of the way to the house is 2/3 * 36= 24 blocks.
Then he rode back to his house (1 - 2/3) * 36= 12 blocks.
Then Joe rode back to grandma's house= 36 blocks.
Then he rode straight home= 36 blocks.
Total number of blocks he rode is 24+12+36+36= 108 blocks.
X^2/3 = 64
it is easier to first find square root of 64 and than power it to 3
square root of 64 is 8 which means our equation now looks like:
x = 8^3
now the answer is after powering 8 to 3:
x = 512
You start by cross multiplying:
9 x 8 = 72
This is considered the fraction on the left's value.
You do the same for the other side:
10 x 7 = 70
This is considered the value of the fraction 7/8
72 has a greater value than 70.
Therefore, 9/10 is larger.
