Step-by-step explanation:
(x-2)²+(y+5)²=25
option C (3.4,-0.2)
LHS= (3.4-2)²+(-0.2+5)²
= (1.4)²+(4.8)²
= 1.96+23.04
= 25
option E(6,-2)
LHS= (6-2)²+(-2+5)² = 4²+(-3)² = 16+9 = 25
Answer:
(-2,2)
Step-by-step explanation:
Looking at your graph, the part were both lines intersect/meet is at point (-2,2). Since (-2,2) is the point of intersection, it is the solution to the equations.
Hope this helps ^-^
10^2 is 10×10 which is 100
4^2 is 4×4 which is 16
so it simplifies to 100-16×2. By Order Of Operations, parentheses, exponents, multiply and divide, add and subtract 100-16×2 makes 100-32 which is 68
Answer:
- x/10 = 9
multiply by 10 on both sides
-x = 90
divided by -1 on both sides
x = -90
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
