Answer:

x - 1

Step-by-step explanation:

4(x+5)-3(7+x)

4( x + 5) = 4x + 20

4x+20-3(7+x)

-3(7 + x) = -21 - 3x

4x+20-21-3x

4x + 20 - 21 - 3x = x-1

Fed [463]

Answer:

Babe Ruth: 714 home runs

Hank Aaron: 755 home runs

Step-by-step explanation:

In this problem, we are told that:

1) Hank Aaron hit 41 more home runs than Babe Ruth during his career

2) Together, they hit a total of 1469 home runs

To solve this problem, we call:

A = the number of home runs made by Hank Aaron

B = the number of home runs made by Babe Ruth

According to statement 1), we have:

A = B + 41 (1)

According to statement 2), we have:

A + B = 1469 (1)

So we have two equations in two unknown variables. If we substitute the expression for A of eq (1) into eq (2), we can solve for B:

(B + 41) + B = 1469

2B = 1469 - 41 = 1428

B = 1428/2 = 714

And substituting back into eq(1), we also find A:

A = B + 41 = 714 + 41 = 755

So:

- Babe Ruth hit 714 home runs

- Hank Aaron hit 755 home runs

I cant solve this help –8x + 15 < 71
Ratling [72]

Answer:

x > -7

Step-by-step explanation:

Isolate the variable, x. Treat the < sign like an equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.

PEMDAS is the order of operation, and stands for:

Parenthesis

Exponents (& roots)

Multiplication

Division

Addition

Subtraction

First, subtract 15 from both sides:

-8x + 15 (-15) < 71 (-15)

-8x < 71 - 15

-8x < 56

Next, divide -8 from both sides of the equation. Note that when you divide by a negative number, you must flip the sign:

(-8x)/-8 < (56)/-8

x < (56)/-8

x > -7

x > -7 is your answer.

Replace f(x) with y
switch x and y
solve for y
replace y with g(x)

y=1/3x+2
x=1/3y+2
x-2=1/3y
3x-6=y
g(x)=3x-6

f(g(x)) should have the same result as g(f(x)) which should be x

f(g(x))=1/3(3x-6)+2=x-2+2=x
g(f(x))=3(1/3x+2)-6=x+6-6=x

the inverse is g(x)=3x-6
