slope = 4

y-intercept = 60

There is a correlation between the number of hours spent on studies and the score on music test.

How to explain the correlation?

As we increase the 0.5 hour on studying, then the music score increases by 2. The function which best fits the data for the correlation is y=60 + 4x

The slope and y-intercept of the plot indicate? that Y= score obtained in music test and X=number of hours spent on studying. The slope of the above equation represent the rate of increase in music score with respect to an increase in the number of hours spent on studying.

The y-intercept gives the music score when the number of hours spent on studying is zero.

The slope of the line below is -3. Which of the following is the point-slope form of the line?​

Answers

Answer:

A. y+6 = -3(x-2)

Step-by-step explanation:

The slope point formula is:

y - y₁ = m (x - x₁)

Our slope is negative 3, and our coordinates given are 2 and -6.

Substitute -3 for m, -6 for y₁, and 2 for x₁

y - (-6) = -3 (x - 2)

Negative and negative multiplied together make postive

A. y+6 = -3 (x-2)

simplify 20 divided by 4+6.2 HURRY

Answers

Answer:Your answer is 2, hope my answer helped!

Step-by-step explanation:

The simplified value of 20 divided by 4+6.2 is approximately 1.96. This means that if we add 4 and 6.2 to get 10.2, then divide 20 by 10.2, the result is approximately 1.96.

To simplify the expression 20 divided by 4+6.2, we need to perform the addition first, and then perform the division.

First, let's evaluate 4 + 6.2:

4 + 6.2 = 10.2

Now, we have 20 divided by 10.2:

20 / 10.2 = 1.96078...

Rounded to a reasonable number of decimal places, the result is approximately 1.96.

Therefore, the simplified value of 20 divided by 4+6.2 is approximately 1.96. This means that if we add 4 and 6.2 to get 10.2, then divide 20 by 10.2, the result is approximately 1.96.

Jasper withdrew $45.00 from her savings account. She then used her debit card to buy groceries for $30.15, and then deposited a check for $14.65. What was the total amount of change in Jasper’s account?

Answers

The total amount of change in Jaspers account is 29.5

Answer:

A money decrease of $60.50 (or -60.50 increase and change)

Step-by-step explanation:

? - 45 - 30.15 + 14.65 = -60.50

Since we are finding the change it is best to replace the question mark with 0 so that it is easier to solve.

0 - 45 = -45

-45 - 30.15 = -75.25

-75.25 + 14.65 = -60.50

Brenda and Cody are selling fruit for a school fundraiser. Customers can buy small boxes of tangerines and large boxes of tangerines. Brenda sold 12 small boxes of tangerines and 1 large box of tangerines for a total of $151. Cody sold 1 small box of tangerines and 3 large boxes of tangerines for a total of $68. Find the cost each of one small box of tangerines and one large box of tangerines

Answers

Answer:the cost of a small box of tangerine= $11 and the cost of a large box of tangerine= $19

Step-by-step explanation:

Step 1

Let price of  small box of tangerines be represented as x

and price of large box of tangerines be represented as y

Such that the equqtion for  Brenda who sold  12 small boxes of tangerines and 1 large box of tangerines for a total of $151 be represented as

12x + y = 151--------equation 1

and

the equation for Cody who  1 small box of tangerines and 3 large boxes of tangerines for a total of $68

x + 3y= 68-------equation 2

Step 2

12x + y = 151--------equation 1

x + 3y= 68-------equation 2

By eliminaton  methd multiply equation 2 by 12

x + 3y= 68-------equation 2 x (12)

12x + 36y=816 --------equation 3

Subtract equation 1 from equation 3

12x + 36y=816 --------equation 3

-12x + y = 151--------equation 1

35y=665

y=665/35 =19

 to get x  , we substitute the value of y=19 into equation2

 x + 3y= 68

x+ 3 x 19=68

x=68-57

x=11

Therefore the cost of a small box of tangerine= $11 and the cost of a large box of tangerine= $19

2/3x+2/3+1/5x=2/3x
20+4r=32-2r

Answers

Answer:

2.3y+3.2-y=2.1+1.3y+1.1

Step-by-step explanation:

The first equation has one solution: z = 0.25.

The second equation has infinitely many solutions.

The third equation has one solution: x = -10/3.

The fourth equation has one solution: r = 2.

What is Equation?

Two or more expressions with an Equal sign is called as Equation.

(a) 2.2z+3z=4.5-3.2

Simplifying the left-hand side, we get: 5.2z = 1.3

z = 1.3/5.2 = 0.25

Therefore, the equation has one solution: z = 0.25.

(b)2.3y+3.2-y=2.1+1.3y+1.1

1.3y + 3.2 = 2.2 + 1.3y

Therefore, the equation has infinitely many solutions.

(c) 2/3x+2/3+1/5x=2/3x

Simplifying the left-hand side, we get: 1/5x + 2/3 = 0

1/5x = -2/3

x = -10/3.

(d) 20+4r=32-2r

6r = 12

r = 2

Therefore, the equation has one solution: r = 2.

Hence, The first equation has one solution: z = 0.25.

The second equation has infinitely many solutions.

The third equation has one solution: x = -10/3.

The fourth equation has one solution: r = 2.

Step-by-step explanation:

If baseball team scored 5 more runs in its second game than its first. The team scored twice as many runs as the first game in the third game. The total number of runs in all three games was 29.Then 11 runs were scored in the second game

What is Equation?

Two or more expressions with an Equal sign is called as Equation.

Let the runs scored by team in first game be x.

The team scored 5 more runs in its second game than its first.

x+5

The team scored twice as many runs as the first game in the third game.

2x

The total number of runs in all three games was 29

This we can write as x+x+5+2x=29

Add x variable terms

4x+5=29

Subtract 5 on both sides

4x=24

x=6

So the score in the second game will be x+5=6+5=11

Hence, 11 runs were scored in the second game
