Given f(x) = 4x -17 and g(x)=5/2x+7;x≠0 solve the equation f^-1(x)=g^-1(x)

Answers

Answer 1
Answer:

Explanation:

f(x) = 4x - 17
f^-1(x) = (x + 17)/4

g(x) = 5/2x + 7
g^-1(x) = 2(x - 7)/5

Solve f^-1(x) = g^-1(x)

(x + 17)/4 = 2(x-7)/5
5(x + 17)/20 = 8(x - 7)/20
5x + 85 = 8x - 56
-3x = -141
x = -141/-3
x = 47

What is the value of 5(-3)?

Answers

Answer. -15
Explanation. We know that a positive multiplied by a negative (or vice versa) equals a negative. If it’s confusing, you can even take out the negative and add it at the end. Remember, 1 negative means the answer is negative, 2 negatives means the answer is positive, and two positives are just positive (this is used for multiplication and division ONLY). So, to solve, 5•3 is 15, and just make it negative, -15!
good luck :)

help please! I am doing multivariable equations. ​

Answers

Answer:

(c+3b)/8 = a

Step-by-step explanation:

c = 8a -3b

Add 3b to each side

c +3b = 8a-3b+3b

c +3b = 8a

Divide each side by 8

(c+3b)/8 = 8a/8

(c+3b)/8 = a

Answer: a=3/8b+c/8

Explanation: c=8a-3b, if you're wanted to solve for a you need to subtract 8a from both sides, c-8a=-3b then subtract c from both sides, -8a=-3b-c then divide both sides by -8 a=3/8b+c/8

Answers

Answer:B have it ✅

Step-by-step explanation:

The value of x for the given equilateral triangle is 28.

What is an equilateral triangle?

A triangle having all sides equal and each angle measures 60° is called

an equilateral triangle.

Given that, the measure of each angle in an equilateral triangle is represented by the expression 2x + 4.

We know that each angle in an equilateral triangle measures 60°

Therefore, 2x+4= 60

2x = 56

x = 28

Hence, the value of x is 28.

A cube has an edge measuring 4 inches. What is the surface area of the cube, in inches²?

Answers

Answer: 96 in2

Step-by-step explanation: This is because u have to mutiple the two bases and the lateral sides to get your area

The surface area of the cube, in inches² is 96in²

The formula for calculating the surface area of a cube is expressed as:

S = 6L²

L is the side length of the cube

Given that L = 4in. Substitute the given parameter into the formula:

S = 6(4)²

S = 6(16)

S = 96in²

Hence the surface area of the cube, in inches² is 96in²

(-13)2= (15* -11 + -4)

the 2 is an exponent

Answers

Answer:

-26= 15 x -15

Step-by-step explanation:

Sorry the question wasn't really clear??

Answer:

(-13)^2= (15* -11 + -4) = -169

Step-by-step explanation:

Replace all occurrences of + − with a single − . A plus sign followed by a minus sign has the same mathematical meaning as a single minus sign

because1 x −1 = −1

(−13)^2=15 x −11 −4

Raise − 13 to the power of 2 .

169=15 x −11 −4

Multiply 15 by −11.

169 = −165 − 4

and finally Subtract 4 from−165.

169 = −169

if its (-13)^2 / (15*-11+-4) as the orginal post did not say divided, the answer would be -1 hope his helps.

A taxi charges $2.50 for each ride plus $1.25 per mile traveled.
If the total charge for one ride was $8.75, how many miles
were traveled?

Answers

Answer:

5 miles

Step-by-step explanation:

We have to figure out how many times $1.25 was charged. First, we have to do 2.50 + 1.25 = 3.75 + 1.25 = 5 + 1.25 = 6.25 + 1.25 = 7.5 + 1.25 = 8.75

We charged $1.25 5 times, so this means that it was 5 miles.

Answer:

5 miles

Explanation:

this is because if you subtract 2.50 from 8.75 then you will be left with 6.25. after you do this then you divide 6.25 by 1.25 and this will give you 5 miles.
