Answer:

-9

Step-by-step explanation:

2(n+6) -15 = 5n+18

2n + 12 - 15 = 5n + 18

2n - 3 = 5n + 18

2n = 5n + 21

-3n = 21

n = -9

Given that (-8,- 7) in on the graph of f(x), find the corresponding point for the fuction f(x -4)
kiruha [24]
The point (x1,y1) on the graph of f(x) is the point (x1-a,y1) for the function
f(x+a)

(-8,-7)=(x1,y1)→x1=-8, y1=-7
f(x-4)=f(x+a)→a=-4

(x1-a, y1)=(-8-(-4), -7)=(-8+4, -7)=(-4,-7)

<span>The corresponding point for the fuction f(x -4) is (-4,-7)</span>

Solve the following:
Yuliya22 [10]

Answer:

-4

Step-by-step explanation:

9^2+19/(10^2-5^3)

9^2+19/(10^2-5^3)=81+19/100-125

9^2+19/(10^2-5^3)=81+19/100-125=100/-25

9^2+19/(10^2-5^3)=81+19/100-125=100/-25= -4
