Answer:
the answer is 16
Step-by-step explanation:
x^2 + 7 ( x=3)
3^2 + 7
9 + 7 =
16
x^2 would be that number(x) times itself that many times[ in this case it would be the number 2]
Fraction wise: 19/225
decimal wise: 0.084444444
Answer:
45%
Step-by-step explanation:
i believe it to be true
The screen us very blurry
4x + 5y = -13
2(4x + 5y) = 2(-13)
8x + 10y = -26 (equation 1)
5x - 2y = -8
5(5x - 2y) = 5(-8)
25x - 10y = -40 (equation 2)
equation 1 + equation 2,
(8x + 10y) + (25x - 10y) = (-26) + (-40)
8x + 10y + 25x - 10y = -26 + -40
33x = -66
x = -2
substitute x = -2 into equation 1,
8x + 10y = -26
8(-2) + 10y = -26
-16 + 10y = -26
10y = -10
y = -1
The values of x and y are -2 and -1 respectively.
