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!
The answers are A and B, -5 and -1. Hope this helps!
Answer:
y=4
x= 3/7
Step-by-step explanation:
2y=8
Divide both sides by 2
2y÷2=8÷2
A.) y=4
Substitute 4 for y
7x−2y=−5
7x+(−2)(4)=−5
Simplify both sides of the equation.
7x−8=−5
Add 8 to both sides
7x−8+8=−5+8
7x=3
Divide both sides by 7
7x÷7= 3÷7
x= <u>3</u>

Answer:
E. 31
Step-by-step explanation:
Add the values together.
4 (2/6) + 3 (3/6) + 2 (3/6) = 9 (8/6) or 10 (1/3)
multiply 10 by 3 to find how many thirds there are and add 1 to that number for the extra 1/3.
Answer:
Step-by-step explanation:
<u>We know that:</u>
- -4 + x = 16 [x = difference between two temperatures]
<u>Solution:</u>
- -4 + x = 16
- => x = 16 + 4
- => x = 20
Hence, the difference between the two temperatures is 20°.
