Answer:

y=4x

Step-by-step explanation:

a proportional relationship has to cross through the origin and all of the other answers have y intercepts and if it has a y intercept then it will not pass through the origin.

Answer:

X(6, 1), Y(-4, 0), Z(-1, 3)

Step-by-step explanation:

When reflecting an image across the y-axis, (i.e, across a vertical line at the position x = 0), All you need to do is negate the x coordinate of each point, so:

(-6, 1) becomes (6, 1)

(4, 0) becomes (-4, 0)

(1, 3) becomes (-1, 3)

Answer:

(6,1) (-4,0) (-1,3)

6. 11 and 71

7.  27.5 and 39.25

Answer:8124

Step-by-step explanation:

Answer:

You would move each point on y=P(x) up by three. Or add 3 to each y coordinate

Step-by-step explanation:

This is because we're not manipulating the value of x before it gets multiplied by P.

For example:

If x is set to equal 5 and P equal to 2, then the parent function would have a coordinate of (5,10) since 2(5)=10 but the new function would have a coordinate of (5,13) since 2(5)+3= 13 due to order of operations (2×5 =10, then we add 3).

Answer:

Step-by-step explanation:

Step 1:

Plot y=P(x) from x=-a to x=a with x=0 as the middle point of the distance between a and -a.

Step 2:

Add the value of +3 to each point of y=P(x), ie, y=P(x)+3 meaning that the graph y=P(x) will be pulled up three units on the y axis.

Answer:

-23

Step-by-step explanation:

6×-4 -1.... (6)(-4)-1

-24-1.....-24-1

-23

Answer:

the second number

Step-by-step explanation:

EX:  ( -3, 2 ) the 2 would lie on the y axis because its the second number the x axis always comes 1st and the y axis 2nd

Answer:

A. $23.34

Step-by-step explanation:

The computation of the amount of money spend altogether is given below:

= Purchase price of 4 binder + pack of pencils + new coat

= $2.14 + $1.25 + $19.94

= $23.34

We simply added the above three cost so that the total money incurred would be come

Hence, the correct option is A

Answer:

245

Step-by-step explanation:

This is a ratio

7/10 = 70% = the kids who picked summer which leaves off as 30% for an unknown season

    7 : 10

245 : 350

The 7 is how many students chose summer, and the 10 is the number of students there are in general

The 245 is the number of students who chose summer, and the 350 is the number of students there are in general

All we had to do was see how many times 10 goes into 350, which is 35 times. So we multiply 10 by 35 and we get 350. Now whatever we do on one side, we need to do it to the other. So 7 times 35 gives us 245. And that's how I know that out of the 350 students there are in total, 245 of them chose summer.

Hope this helped!

Answer:

no(double check my math!!)

Step-by-step explanation:

on the second step it should be 4 not 16 bc 10-6=4

2x-8+3x+2=4x+10+3x-6

5x-6=7x+4

-6=2x+4

-10=2x

-5=x

Answer:

1/9

Step-by-step explanation:

6 feet = 6*12 = 72

Scale factor = 8/ 72 = 1/9

Answer:

1/9

Step-by-step explanation:

6ft = 72 inches

8/72 = 1/9

Answer:

Option c, d and e are equivalent expressions to 7x-14

Step-by-step explanation:

Which expressions are equivalent to 7x - 14

Equivalent Expressions:

The expressions that are the same, even if the expression looks different.

For example: 2x^2+4 is equivalent to 2(x^2+2) because solving 2(x^2+2) we get 2x^2+4

Now, finding equivalent to expressions 7x - 14

Option a) 14 - 7x

Not equivalent to 7x-14

Option b) x-2

Not equivalent to 7x-14

Option c) -(14 – 7x)

Simplifying: -14+7x so, equivalent to 7x-14

Option d) (x - 2)

Simplifying: 7x-14 so, equivalent to 7x-14

Option e) - 14 + 4x

Simplifying: 3x+4x-14 = 7x-14, so, equivalent to 7x-14

Option f) 2x - 10 + 5x + 4

Simplifying: 2x+5x-10+4 = 7x-6 so, Not equivalent to 7x-14

So, Option c, d and e are equivalent expressions to 7x-14

Answer:

n=-3.1

Step-by-step explanation:

To solve this, first subtract 3 from both sides of the equation to get 2n=-6.2. Next, divide both sides of the equation by 2 n order to get the final answer of n=-3.1

Answer:

  2

Step-by-step explanation:

The question is asking the value of f(5). Put 5 where x is and do the arithmetic.

  [tex]f(x)=\dfrac{5x-15}{5}=x-3 \qquad\text{simplified}\\\\f(5)=5-3=\boxed{2}[/tex]

The range value of interest is 2.

Answer:

Step-by-step explanation:

[tex] \frac{6}{x - 1} = \frac{4}{x + 2} [/tex]

[tex]6x + 12 = 4x - 4[/tex]

[tex]6x - 4x = - 12 - 4[/tex]

[tex]2x = - 16[/tex]

Answer:DE = 4

AB = 30

Step-by-step explanation:

Answer:

30cm²

Step-by-step explanation:

AE/BD = CE/CD

9/6 = CE/8

CE = 9/6 x 8

CE = 12cm

DE = CE - CD

DE = 12 - 8 = 4 cm

½(6 + 9)4 = 30cm²

1) 12/1

2) 517/100

3) 2/25

4) 67/800

5) 5/2
