30 and 13
x-y=17 and x+y=43
x=17+y and x=43-y, so 17+y=43-y
so y=13
43-13=30, so x=30 and y=13
Answer:
(x+1)² + y² = 36
Step-by-step explanation:
<u>Equation of a circle:</u>
(x-h)² + (y-k)² = r²
Center: (h,k)
Radius: r
Given a center of (-1,0) and a radius of 6, we have for our equation:
(x-(-1))² + (y-0)² = 6²
(x+1)² + y² = 36
Answer:
AC ≈ 2.87
Step-by-step explanation:
Using the sine ratio in the right triangle
sin35° =
=
= ![\frac{AC}{5}](https://tex.z-dn.net/?f=%5Cfrac%7BAC%7D%7B5%7D)
Multiply both sides by 5
5 × sin35° = AC , thus
AC ≈ 2.87 ( to the nearest hundredth )
2 1/4 + 1 2/4 ≠ 5
Why?
2 1/4 + 1 2/4
=3 3/4
The answer is wrong because the student added wrong. The real answer is 3 3/4.
