Given

[tex]\frac{2}{3}[/tex] m + 5 = 17 ( subtract 5 from both sides )

[tex]\frac{2}{3}[/tex] m = 12 ( multiply both sides by 3 to clear the fraction )

2m = 36 ( divide both sides by 2 )

m = 18 → C

If f(x) = 7-2x , find [f(3)+6] ^2

Answers

answer: 49

explanation:
first, substitute f(3) in the expression. you do this by substituting x for 3 in f(x) = 7 - 2x so that equation becomes f(3) = 7 - 2(3) and solve to find that f(3) = 1.

f(3) = 7-2(3)
f(3) = 7-6
f(3) = 1

then substitute this into the expression and solve

(f(3)+6)^2
(1+6)^2
(7)^2

Convert factored form to standard form

Answers

Answer:

[tex]y - 7x = 21[/tex]

Step-by-step explanation:

Given

[tex]y = (x + 4)7 - 7[/tex]

Required

Convert to standard form

[tex]y = (x + 4)7 - 7[/tex]

Start by opening the bracket

[tex]y = x*7 + 4*7 - 7[/tex]

[tex]y = 7x + 4*7 - 7[/tex]

[tex]y = 7x + 28 - 7[/tex]

[tex]y = 7x + 21[/tex]

Subtract 7x from both sides

[tex]y - 7x = 7x - 7x + 21[/tex]

[tex]y - 7x = 21[/tex]

Hence:

The standard form is: [tex]y - 7x = 21[/tex]

A group of friends wants to go to the amusement park. They have $94.25 to
spend on parking and admission. Parking is $14.75, and tickets cost $13.25
per person, including tax. Write and solve an equation which can be used to
determine p, the number of people who can go to the amusement park.

Answers

Answer:

1) The equation to determine the the number of people who can go to the amusement park is 14.75 + 13.25·p = 94.25

2) The number of people who can go to the amusement park is people

Step-by-step explanation:

The given parameters are;

The amount the group of friends have to spend on parking and admission = $94.25

The cost parking = $14.75

The cost of tickets per person = $13.25

The variable we let to represent the number of people who can go to the amusement park be "p"

1) The equation that can be used to determine "p" is therefore, given as follows;

14.75 + 13.25·p = 94.25

2) Therefore, we have, by making "p" the subject of the above equation;

p = (94.25 - 14.75)/13.25 = 6

Therefore, the number of people who can go to the amusement park, p = 6 people.

Answer:

Answer: 6

Step-by-step explanation:

Equation: 13.25p+14.75=94.25

Answer:

F altitude

Step-by-step explanation:

AB is perpendicular to triangle base XZ, so is an altitude of the triangle.

Additional comment

B is not the midpoint of XZ, so AB is not the median and not a bisector of XZ. Likewise, AB is not the angle bisector of angle A. (The triangle would have to be isosceles for AB to be a perpendicular bisector, median, and angle bisector.)

Eliminating the choices that can't work leaves the one that does work. AB is the altitude.

If a sweatshirt normally costs $40 but it is
marked down 20%. How much would it cost?

Answers

Answer:

Step-by-step explanation:

First, find 20% of 40.

20% as a decimal is 0.20 (20/100)

0.20 x 40 = 8

Now, subtract 8 from the original price.

40 - 8 = 32

Answer:

$32

40 decrease 40%

40 x (1-20%) = 40 x (1-0.2) =32

Function g is a transformation of the parent exponential function. Which statements are true about function g?
FAKE ANSWERS WILL BE REPORTED!!

Answers

Using function concepts, it is found that the correct options are:

Function g is positive over the interval [tex](-\infty, \infty)[/tex].The range of function g is [tex](3, \infty)[/tex].Function g has a y-intercept of (0,4).

What is the parent exponential function?

The parent exponential function is defined by:

[tex]y = e^x[/tex]

In this problem:

When [tex]x = 0, e^x = 1[/tex], while [tex]g(x) = 4[/tex] when x = 0, hence it is 4 - 1 = 3 units above function f.From the graph, it is above the x-axis in the interval [tex](-\infty, \infty)[/tex], hence it is positive in this interval.The range is the set that contains all output values, that is, all values of y, hence it is [tex](3, \infty)[/tex].The domain is the set that contains all possible input values, hence it is [tex](-\infty, \infty)[/tex].The y-intercept is (0, g(0)), hence (0,4).Function g is increasing over the entire interval.

Jenna has already cycled 8 kilometers this year,plus she plans to cycle 2 kilometers during each trip to work.Write an equation that shows the relationship between the number of trips to work t and the total distance cycled d.

Answers

Answer:

[tex]d = 8 + 2t[/tex]

Step-by-step explanation:

Given

[tex]Rate = 2km/trip[/tex]

[tex]Base\ Cycle = 8km[/tex]

[tex]d = total\ distance[/tex]

[tex]t = cycles[/tex]

Required

Determine the expression for this scenario

The expression can be derived from:

[tex]Total\ Distance = Base\ Cycle + Rate * Cycles[/tex]

Substitute d for Total Distance and t for cycles

[tex]d = Base\ Cycle + Rate * t[/tex]

Substitute values for Base Cycle and Rate

[tex]d = 8 + 2* t[/tex]

[tex]d = 8 + 2t[/tex]

Answers

Answer:

B x = 7

Step-by-step explanation:

You know based on the ratio that it's being scaled by 4 times because the one side 4 is 16 in the bigger pentagon.

So if you go the side that matches the one you need to solve, it's 2.5.

2.5 times 4 = 10 so that bigger pentagon side should equal 10.

The equation x-3 = 10

which means x is 7
