O B. (15,0)
O C. (0,15)
O D. (24,0)

Answers

Answer:

(0,15)

Step-by-step explanation:

The Y-intercept is when X=0, so plug in x=0 into the given equation. 5(0)+8y=120. Now solve for Y. 8y=120, y=15. So When x=0, y=15: this is the coordinate (0,15).

PROBLEM: Juan hires an electrician. Juan pays a one-time fee of $30. Juan also pays $45 for each hour the electrician works. A. Write a function that can be used to find the total charge, c, Juan will pay when the electrician works, h, hours. Y=mx+b B. How much will Juan pay if it takes the electrician 6 1/2 hours to complete the job? (Vou should have 9 answers in question 2

Answers

Answer:

A: C=45h+30

B: C=$322.50

Step-by-step explanation:

A: We'll start with the equation for the total charge. Juan is saying he will pay a one time fee of $30, meaning there is 30 dollars added to what ever the hourly wage is. This can be represented by the +30. Now if "h" represents the variable for which the hourly wage will be calculated, and he pays $45 dollars per hour this will be represented as 45h. As an example if I pay you 2 dollars per hour using the same variable "h", this would be represented as 2h. So if you worked for two hours you would get 4 dollars, this is proven by the fact the 2(2) (remeber im replacing the "h" with the hours you worked) obviously 2 times 2 is 4 proving my point. This information will give you the equation you see above.

B: Onto solving for how much Juan will pay. Now you say youre supposed to have 9 answer but this can't be true. All you need to do is plug the hours given into "h" and solve the equation. It should look something like:

C=45h+30

C=45(6.5)+30

Im using a decimal because it should be clear 1/2=0.5

C= 292.5+30

45x6.5 always go with PEMDAS, we are multiplying first. Then add 292.5 plus 30

This results in the answer of:

C=$322.50

Martin is ordering DVDs online. Each DVD is priced at $8.50. The website also charges a flat fee of $5.00 for shipping and handling for any size order. If Martin decides to spend no more than $56, how many DVDs can he buy?

Answers

Answer:

Step-by-step explanation:

...

The solution is Option A.

The inequality equation is A ≤ 6 where A is the number of DVDs Martin can buy

What is an Inequality Equation?

Inequalities are the mathematical expressions in which both sides are not equal. In inequality, unlike in equations, we compare two values. The equal sign in between is replaced by less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.

In an inequality, the two expressions are not necessarily equal which is indicated by the symbols: >, <, ≤ or ≥.

Given data ,

Let the total number of DVDs Martin can buy be = A

Now , the equation will be

The price of 1 DVD is = $ 8.50

The price for shipping and handling = $ 5.00

Now , the total amount Martin decides to spend = not more than $ 56

So , the inequality equation will be

8.50A + 5 ≤ 56

On simplifying the equation and solving for A , we get

Subtracting 5 on both sides of the equation , we get

8.50 A ≤ 51

Divide by 8.50 on both sides of the equation , we get

A ≤ 51 / 8.5

A ≤ 6 DVDs

So , the value of A should be less than or equal to 6

Hence , the inequality equation is A ≤ 6 where A is the number of DVDs Martin can buy

Answer:

h = -2; k = 0; vertex = (-2, 0)h = 3; k = 0; vertex = (3, 0)

Step-by-step explanation:

Translation of a function to the right h units and up k units is accomplished by ...

g(x) = f(x -h) +k

Here, we have f(x) = |x|, so the translation will be ...

g(x) = |x -h| +k

or ...

y = |x -h| +k

The function y = |x| has its vertex at (0, 0), so translation by (h, k) moves the vertex to (0 +h, 0 +k) = (h, k).

You will notice that the given equations you are given have no "+k" added on, so k = 0 in both cases. The value of h is the opposite of the constant between the absolute value bars.

1. y = |x +2|

h = -2, k = 0

vertex: (-2, 0)

2. y = |x -3|

h = 3, k = 0

vertex: (3, 0)

Additional comment

This is all about matching patterns. You need to be able to identify the variable (x) and what has been added or subtracted to/from it. You need to be able to identify the "parent" function (what you have with nothing added or subtracted), and determine if something is added or subtracted to to/from that. Here, the parent function is |x|. Nothing has been added to the function (outside the absolute value bars), but something has been added to x (inside the absolute value bars).

Which of the following lists the sides of △DEF in order from shortest to longest?

Answers

Answer:

The 2nd option.

Step-by-step explanation:

Since Angle D is 68 degrees side EF would be the longest.

Side DF is the shortest side it is opposite the smallest angle.

Side EF is in the middle since opposite the next biggest angle.

Side EF is again the longest since Angle D is the biggest at 68 degrees.

A set of stickers contains 4 hearts for every 6 stars. Which choice contains an equivalent ratio of hearts to stars? A. 6 hearts to 9 stars B. 8 hearts to 10 stars C. 1 heart to 3 stars D. 2 hearts to 4 stars

Answers

Answer:

6 hearts to 9 stars

Step-by-step explanation:

If a set of stickers contains 4 hearts for every 6 stars, this means that

4 hearts = 6stars

1 heart = x

Cross multiply

4x = 1*6

4x = 6

x = 6/4

x = 3/2

Number of hearts = 3/2 * 4 = 3*2 = 6

Number of stars = 3/2 * 6 = 3 * 3 = 9

Hence equivalent ratio of hearts to stars is 6 hearts to 9 stars

The rate (in meters per second) that an object travels is the quotient of the distance (in meters) it travels and the time (in seconds) it takes to travel that distance. A particle traveled the distance of 3x^2-12 meters for ( x + 2 )seconds. Write the rate of the particle as a rational algebraic expression in simplest form.

Answers

Rate

= Distance / Time

= (3x² - 12)m / (x + 2)s

= 3(x + 2)(x - 2)m / (x + 2)s

= 70 + 5g

Therefore, the total cost for a party

with 9 guests will be:

= 70 + 5g

= 70 + 5(9)
