Its 80 because if you find perfect square around the number 80 you'd get
√64 and √81
which would be 8 and 9
Step-by-step explanation:
replaced f(x) with 5
5= x^2 +4
5 -4 = x^2
1 = x^2
take the square root on both sides
- 1 or 1 = x
Answer:
C) a = 6 D) m = 5
Step-by-step explanation:
C) 3a + 11 = 7a - 13
4a = 24
a = 6
D) 2m + m - 8 = 7
3m = 15
m = 5
Answer:
b, y = 9x + 7
Step-by-step explanation:
Since the graph y = 9x + 10 is being "translated" 3 units down, that means the slope of the equation remains the same, but the y intercept is being moved 3 units down.
y = mx + b
y-intercept = b = 10
10 - 3 = 7
the answer is b, y = 9x + 7
It’s
X = 9 if you was looking for x
