Answer:

Y= 0

Step-by-step explanation:

A proportional relationship is when two numbers change at a constant rate. They always are modeled by y = kx, which in this case, would be y = 5/3x. The y-intercept would be added to the equation, as y = kx + b, in this case would be y = 5/3x + 0, or the previous equation.

1. How do you subtract an integer from another integer without using a number line?

2. Rewrite each following subtraction problems as addition problems

1) 5-11 2) 15- 21


3) 0-(-5) 4) 19-(-19)



5)-3-(-5) 6)-87-(-87)



7)-17-1


3. When Tom found the difference -11-(-4), he got -15. What might Tom have done wrong?


4. When you subtract one negative integer from another, will you answer be greater than or less than the integer you started with? Explain your reasoning and give an example.

5. Theo had a balance of -$4 in his savings account. After making a deposit, he has $25 in his account. What is the overall change to his account? Show all your steps.

Answers

Answer:

1) Remember to change the signs when necessary. For example, when you're subtracting a negative with another negative, you add the two numbers to form a bigger negative.

2)

1)) -6 + 11 = 5

2)) -6 + 21 = 15

3)) 5 + 0 = 0

4)) 19 + 19 = 38

5)) (-5) + (-3)

6)) -87 + 87 = 0

7)) -1 + -17 = -18

3) Tom didn't change the sign to make a +, instead he left it as one negative sign and a subtraction sign.

4) The answer will be of a greater value as the two negatives would cancel each other out. For example, -9 - (-9) would end up being 0 as the sign change would make one 9 positive.

5) $-4 + $29 = $25 He added $29 dollars to his bank account, turning himself out of debt.

The table represents a linear function. A two column table with six rows. The first column, x, has the entries, negative 2, negative 1, 0, 1, 2. The second column, y, has the entries, negative 8, 2, negative 4, negative 10, negative 16. What is the slope of the function?

Answers

Slope of function = 10
m = 10

The slope of the line will be +10.

What is the general equation of a Straight line?

The general equation of a straight line is -

[y] = [m]x + [c]

where -

[m] → is slope of line which tells the unit rate of change of [y] with respect to [x].

[c] → is the y - intercept i.e. the point where the graph cuts the [y] axis.

We have a table that represents a linear function.

We have -

[x]        [y]

-2          -8

-1            2

0          -4

1           -10

2          -16

The slope of the function can be calculated as -

m = (2 + 8)/(-1 + 2) = 10/1 = 10

Therefore, the slope of the line will be +10.

Lets start by finding out the cordinates first!

these are the ones we start off with!

D (1,1)  

E (2,2)

F (4,2)

G (3,1)

now we need to find the prime image cords.

D' (4,4)

E' (8,8)

F' (16,8)

G' (12,4)

now what we are tying to find is the scale factor, so we need to check what number is multipled by those cordinates to get the prime cordinates.

D is (1,1) and D' is (4,4) but we know that 1x4 is 4 so 4 is the scale factor that we multiply all the numbers by ! i hope that made sense !

Answers

Answer:

7.5

Step-by-step explanation:

Since the angle shown is 90 degrees we can deduce that the rest of the arc is 270 degrees therefore we can make the fraction:

270/360; 360 being the total angle measurement of a circle

270/360 simplifies to 3/4

The fraction represents how much of the circle that arc covers

Now we have to find the circumference which would be

2([tex]\pi \\[/tex])r

r = 5 therefore: 2([tex]\pi \\[/tex])5 = 10[tex]\pi \\[/tex]

Now that we have the circumference of the WHOLE circle we multiply it by 3/4 to find out the arc length

Which gives us 7.5[tex]\pi \\[/tex], or 23.55

The correct answer is 7.5

What is the slope of the line?

Answers

Answer:

2/3

Step-by-step explanation:

Step 1

(1,2) (4,4)

First we are going to pick two point on the line.

Step 2

(y2-y1) / (x2-x1)

(4-2) / (4-1)

in the first set we label x as x1 and y as y1, then we do the same with the other set but with x turning into x2 and y turning into y2. We then plug them into the equation.

Step  3

(2)/(3)

or

2/3

Now we solve what is in the parentheses (4-2) is 2, and (4-1) is 3. We then take away the parentheses and have 2/3. keep 2/3 as a fraction, do not change it to a decimal.

The answer would be 2/3

Which size can of soup shown in the table has the lowest unit price? ​

Answers

Answer.
Explanation. Let’s get all of the options down to the 1 ounce unit to determine the price per oz. we can do this by dividing the cost by the size.
0.79/10= 0.079 per oz
1.29/15=0.086 per oz
2.16/18=0.12 per oz
3.19/32=0.099 per oz
By looking at all of the options, we find that the 10 oz can has the lowest unit price. Hope this helps, let me know if it’s correct so others can use it :)
Good luck.

The can of size 10 has the lowest unit price.

What is Unit Rate?

Unit rate is the amount of one quantity for a unit amount of the other quantity.

In other words it compares 1 unit of some quantity with different amount of another quantity.

We have to find the unit rate.

For size 10 :

Cost of 10 oz of soup = $0.79

Cost of 1 oz of soup = 0.79 / 10 = 0.079

For size 15 :

Cost of 15 oz of soup = $1.29

Cost of 1 oz of soup = 1.29 / 15 = $0.086

For size 18 :

Cost of 18 oz of soup = $2.16

Cost of 1 oz of soup = 2.16 / 18 = $0.12

For size 32 :

Cost of 32 oz of soup = $3.19

Cost of 1 oz of soup = 3.19 / 32 = $0.0997

The smallest unit price is for can of size 10.

Hence the lowest unit price is for the can of size 10.
