The sum of three consecutive rven integers is 72. Let x represent the first integer, x+2 represent the srcond integer, and x+ 4

Vsevolod [243]

Given parameters:

First term of the sequence = x

Second term = x + 2

Third term = x + 4

Sum of the first three terms = 72

Unknown:

First term of the sequence = ?

Solution:

The sum of the first three terms is unknown;

(x) + (x + 2) + (x + 4) = 72

Solve for x;

x + x + 2 + x + 4 = 72

3x + 6 = 72

3x = 72 - 6

3x = 66

x = $\frac{66}{3}$ = 22

The first term of the sequence is 22

Given g(x)=sqrt x-4 and h(x)=2x-8 what is (g(h(10)) HELP ME I AM .3 POINTS AWAY FROM PASSING.

Whitepunk [10]

The answer (g(x))=x−7

g(f(x))=√x2−7

Explanation:

Put g inside f to find f(g(x))

f(x)=x2−4

g(x)=√x−3

f(g(x))=(√x−3)2−4

f(g(x))=x−3−4

f(g(x))=x−7

Put f inside g to find g(f(x))

g(x)=√x−3

f(x)=x2−4

g(f(x))=√x2−4−3

g(f(x))=√x2−7:

The answers are f(g(x))=x−7
and g(f(x))=√x2−7

Explanation:

This is a composition of functions.

f(x)=x2−4

g(x)=√x−3

fog(x)=f(g(x))=f(√x−3)=(√x−3)2−4

=x−3−4=x−7

And

gof(x)=g(f(x))=g(x2−4)=√(x2−4)−3

=√x2−4−3=√x2−7

You can see that

f(g(x))≠g(f(x))

Y = 2x – 15 y = 5x Can anyone tell me the steps how to solve this and the answer

Brilliant_brown [7]

Use substitution
Plug in 5x for y
5x = 2x - 15
Subtract 2x
3x = -15
Divide by 3
x = -5, y = -25
Solution: (-5, -25)
