Slope Intercept Form is y=2x.

Step-by-step explanation:

Since slope-intercept form is y=mx+b, you need to rewrite 2x-y=0 in Slope-Intercept Form.

First, you want to subtract 2x from both sides. That comes out to -y = (-2x.)

Then, multiply each term by -1. A negative times another negative is a possitive, so -y would become y, and -2x would become 2x, giving you the answer of y=2x.

The zero pairs that can be created in the model 2 x tiles and 1 negative x tile. 3 plus sign tiles and 2 negative tiles is '12'.

A pair of numbers that add up to zero is referred to as a zero pair. The two numbers must contain both a positive and a negative number, according to the concept of a zero pair.

Combination of all zero pair:

The given data is, 2 x tiles and 1 negative x tile. 3 plus sign tiles and 2 negative tiles.

Rewrite the combinations as below,

[x] [-x]   [+] [-]

[x]         [+] [-]

            [+]

Formation of zero pair combinations:

[x][-x]

[-x][x]

[x][-][x]

[x][+][-][x]

[+][x][+][-][x]

[x][+][-x]

[-][x][x]

[-][x][+][x]

[+][x][+][-x]

[-][-x][-][x]

[-][x][-][-x]

[-][-x][+][-][x]

Therefore, the total number of combinations used for making zero pair are '12'.

Answer:

m<4 = 117 degrees

Step-by-step explanation:

Knowing that angle 1 is 63 degrees, we can look at the other angle on the same side of the line, angle 4.

Angles on one side of a line add to 180 degrees.

180 - 63 = 117

Answer:

Area of the rectangle is 300, The perimeter is 70.

Step-by-step explanation:

Area = length x width

Area = 20 x 15

Area = 300

Perimeter = 2 x (length + width)

Perimeter = 2 x (20 + 15)

Perimeter = 2 x 35

Perimeter = 70

Answer: A, B and F are all true

Step-by-step explanation:  Multiplying the fractions, we get the product, 2/15 so A is correct.

When he divides each third into five parts, each of those parts is 1/15 of the whole, so B is correct.

He shades two of those parts is given, so F is correct.

Answer:

Step-by-step explanation:

A manager gives gift cards to every 80th customer. On Saturday, 1210 customers entered, while on Sunday, 1814 customers entered. We are asked to find the number of people who received gift cards.

Consider Saturday:

(1) Probably the most efficient method is to divide 1210 by 80.

(The first gift card was given to the 80th person and 80/80=1. The second to the 160th person and 160/80=2. The third to the 240th person and 240/80=3, etc...)

So 1210 divided by 80 is 15 with a remainder of 10.

15 people received gift cards on Saturday.

(2) We could set up a linear inequality where the unknown x represents the number of people receiving gift cards. Then 80x<1210 and x<15.125 so x=15.

(3) You could just keep adding, perhaps in a table, until you got to the last person:

(# customers, # gift cards): (80,1), (160,2), (240,3)...(1120,14), (1200,15)

The answer will not change, but the manager can either start counting at zero again on Sunday, or continue from the previous day making the first person in on Sunday number 11.

Again we take 1814 divided by 80 to get 22 with a remainder of 54. (With the additional 10 from Saturday we would have remainder 64, but still not enough people to give out another card.)

15 cards given out Sat with 22 cards given out Sun means that there were a total of 15+22=37 people who received gift cards.

Answer:

Natalie: 12

Fred: 24

Step-by-step explanation:

x= natalie

y= fred

x+y=36

y+4x=72

Let's start by isolating a variable

x+y=36

x-36= -y

-x+36=y

(we do this step because it's important that the y is a negative)

We can plug this into the second equation

-x+36+4x=72

solve for x

3x=36

x=12

Plug in this x value into any of the two beginning equations

12+y=36

y=24

Answer:

B:9

Step-by-step explanation:

the exponents cancel each other out so you are left with 3^2

3 multiplied by 3 equals 9

Answer:

9

Step-by-step explanation:

When dividing the same base raised to an exponent, you can simply subtract the denominator's exponent from the numerator's.

In this case then, we have 3⁴ / 3², which is exactly the same as 3⁽⁴⁻²⁾, or 3².

Three squared is equal to nine, and that is the answer.
