Mike compared the y-intercept of the graph of the function
f(x) = 5x + 12 to the y-intercept of the graph of the ilnear function that
includes the points from the table below. What is the difference when the y-
intercept of f (x) is subtracted from the y-intercept of g (x)?
Х
1 3 5 6
g(x) 10 14 18 20

Answers

Answer:

-4

Step-by-step explanation:

Given function

f(x) = 5x + 12

From the table we get the function g(x), use pairs (1, 10) and (3, 14)

The slope:

m = (14 - 10)/(3 - 1) = 4/2 = 2

The y-intercept:

10 = 2(1) + bb = 10 - 2b = 8

The function g(x) is found as:

g(x) = 2x + 8

The y- intercept of f (x) is subtracted from the y-intercept of g (x):

8 - 12 = -4

Answer:

(the answer is • -4)

Olivia has a points card for a movie theater. She receives 25 rewards points just for signing up. She earns 7.5 points for each visit to the movie theater. She needs 130 points for a free movie ticket. How many visits must Olivia make to earn a free movie ticket?

Answers

Answer:

Step-by-step explanation:

7.5x + 25 = 130

-25 -25

7.5x = 105

[tex]\frac{7.5x}{7.5}=\frac{105}{7.5}[/tex]

x = 14

There is a bag filled with 4 blue and 5 red marbles.
A marble is taken at random from the bag, the colour is noted and then it is not replaced.
Another marble is taken at random.
What is the probability of getting exactly 1 red?

Answers

Answer:

im not sure but this is just a guess (please keep it in mind)

Step-by-step explanation:

9-1= 8

1 in 8? or 1 in 9

this is becuase we dont know if the one that was taken out randomly first wasnt a red or not but then i could be wrong and the fact if it was red or blue in the first place might not even matter. it really depends.

1 (x + 4) = 20
x = 48
Help please.

Answers

Answer:

X actually equals 16 becaausw if yiu add 16+4 you get 20 and then you have to multiply 20 by 1 and you get 20 so x=16

Answer:

x = 16

I dont quite understand the x = 48 situation? But thats wrong if that's your answe

Step-by-step explanation:

So you have to find out what x is

in order to do that you have to work out the equation and whatever you do to one side you must do to the other side

simplify 1(x+4) = 20

x + 4 = 20

in order to get rid of 4 on one side you have to subtract it on both sides

so x = 16

40000 people visited the Emirates Park Zoo in Abu Dhabi last Year. Ratio of number of visitors of children to women to men is 4: 7: 9. Find the number of children, women and men who visited the zoo.

Answers

Answer:

40000 total visitors

Step-by-step explanation:

Let p represent a multiplier. Then the total number of visitors to the park is

4p + 7p + 9p = 40000.

This simplifies to 20p = 40000, so that p = 2000.

Then the number of children who visited is 4p = 8000; the number of women is 7p = 14000, and the number of men is 9p = 18000.

Summing up these results gives us the total number of chidren, women and men who visited the zoo last year: 8000 + 14000 + 18000, or 40000.

Which equation represents the solution of the equation 6x – 18 = 30?

Answers

Answer:

x=8

Step-by-step explanation:

Answer:

x = 8

Step-by-step explanation:

rearrange:

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :

6*x-18-(30)=0

STEP 1:

Pulling out like terms

Pull out like factors :

6x - 48 = 6 • (x - 8)

STEP 2:

Equations that are never true:

Solve: 6=0

This equation has no solution.

Solving a Single Variable Equation:

Solve : x-8 = 0

Add 8 to both sides of the equation :

x = 8
