Write an expression that is equivalent to three over four (5z+ 16).

Answers

15 over fourz +12

Using the distributive property, 3/4 • 5z equals 15/4z, which can't be simplified. Then 3/4 of 16 is 12. If you divide 16 by 4 (the denominator) and then multiply by 3 (the numerator) that yields your answer.

You need $125 to buy an MP3 player. Your allowance is $5 per week and you earn $20 per lawn mowed
Write an equation that represents your weekly income in dollars for x lawns mowed. Interpret the y intercept . How many lawns do you need to mow to earn enough money in one week to buy the MP3 player?

Answers

Answer:

Answer in explanation

Step-by-step explanation:

The equation of a straight line can be represented in the form;

y = mx + c

where m is slope and c is y-intercept

In this particular case

y = 20x + 5

y is the weekly income, x is the number of lawns mowed

The y-intercept 5 is the amount earned in a week given they no lawn was mowed

In a case where y = 125

125 = 20x + 5

20x = 125-5

20x = 120

x = 120/20

x = 6

You need to mow 6 lawns to earn enough money in one week to buy the MP3 player

13(3−z)

Answers

Answer:

13(3 - z) = 13(3 - z)

13(3 - z) = 39 - 13z

Step-by-step explanation:

To make the equation have infinitely many solutions, when you simplify, the equation will become z = z

To make this happen, the equation has to be the same on either side of the equal sign. Here are the two options :

13(3 - z) = 13(3 - z)

13(3 - z) = 39 - 13z

What is the x-intercept of the slope of -2 and a y-intercept of 0, 6

Answers

Answer:

x- intercept = 3

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Here m = - 2 and c = 6 , thus

y = - 2x + 6 ← is the equation of the line

To find the x- intercept, let y = 0 in the equation and solve for x

- 2x + 6 = 0 ( subtract 6 from both sides )

- 2x = - 6 ( divide both sides by - 2 )

x = 3 ← x- intercept or (3, 0 )

X-incterpret=3 is the answer you’re look for

Equation of the Quadratic Function

The vertex form of the quadratic function has the following equation:

[tex]y=a(x-h)^2+k[/tex]

Where (h, k) is the vertex of the parabola that results when plotting the function, and a is a coefficient different from zero.

The graph provided in the question, assumed as a parabola, has two clear points:

The vertex, located at (-2,-3)

The point (-1,-6)

Substituting the coordinates of the vertex, the equation of the function is:

[tex]y=a(x-(-2))^2-3[/tex]

[tex]y=a(x+2)^2-3[/tex]

The value of a will be determined by using the other point (-1,-6):

[tex]-6=a(-1+2)^2-3[/tex]

Operating:

[tex]-6=a(1)-3[/tex]

Solving:

a=-3

The equation of the graph is:

Step-by-step explanation:

y=6,x=?

if x is directly proportional to y^3 &if (when x=32, y is=2) we can understand that x=4y^3

1,x=4y^3

x=4(6^3)

x=4(216)

x=864

Ana is going to a craft fair where she'll sell her handmade scarfs. She has six scarf designs, and she's made 15 of each. She's paid $128 for the booth, and each scarf costs $9.80 to make. How much should she charge for each scarf if she wants to break even after selling a third of her scarves?

Answers

Answer:

$33.6667

Step-by-step explanation:

Given the following :

Number of Scarf designs = 6

Number of each made = 15

Total scarfs = (15 * 6) = 90

Cost:

Booth = $128

Production cost per scarf = $9.80

Total production cost = $9.80 * 90 = $882

Total cost = $128 + $882 = $1010

Break even = profit - loss = 0

One third of scarves = 1/3 * 90 = 30

This means he must cover for the total cost of $1010 after selling 30 scarves

Hence price per scarf will be :

$1010 / 30

= $33.6667
