Answer:

567000 dollars

Step-by-step explanation:

Straightforward if 7000 for 3 hours then 3*27=81 and 7000*81=567000

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: a) [tex]\dfrac{13}{7}[/tex]

Step-by-step explanation:

Median: Line segment from one vertex of a  triangle to the midpoint of the opposite side. i.e. it bisects the opposite side.

Centriod: Point of intersection of a triangle of its medians

.Also, it is [tex]\dfrac23[/tex] of the distance from vertex to the midpoint of opposite side.

Given:  CD is a median in triangle ABC and M is centriod.

[tex]\Rightarrow CM=\dfrac23 CD[/tex]

Since CM = x +5 and CD = 5x + 1

[tex]\Rightarrow\ x+5=\dfrac{2}{3}(5x+1)\\\\\Rightarrow\ 3(x+5)=2(5x+1)\\\\\Rightarrow\ 3x+15=10x+2\\\\\Rightarrow\ 10x-3x=15-2\\\\\Rightarrow\ 7x=13\\\\\Rightarrow\ x=\dfrac{13}{7}[/tex]

Step-by-step explanation:

Step 1: Define

-98 = 7t

Step 2: Solve for t

Step 3: Check

Plug in t into the original equation to verify it's a solution.

Here we see that -98 is equal to -98.

∴ t = -14 is the solution to the equation.

Step-by-step explanation:

Step 1: Define

-98 = 7t

Step 2: Solve for t

Divide 7 on both sides: -14 = t

Rewrite: t = -14

Step 3: Check

Plug in t into the original equation to verify it's a solution.

Substitute in t: -98 = 7(-14)

Multiply: -98 = -98

Here we see that -98 is equal to -98.

∴ t = -14 is the solution to the equation.

Step-by-step explanation:

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

Answer:

Step-by-step explanation:

HOPE THAT HELPS!!!!!!!

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:

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

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:

y- intercept = 1

Step-by-step explanation:

The y- intercept is the point on the y- axis where the graph crosses.

This occurs when the x- coordinate is 0

From the table the point (0, 1 ) is where the graph crosses the y- axis

Then y- intercept = 1

Answer:

x= -1.7

Step-by-step explanation:

Isolate the variable by dividing each side by factors that don't contain the variable.

Answer:

x = -1.7.

Step-by-step explanation:

3.7 = 5x + 12.2

Subtract 3.7 from both sides:

0 = 5x + 12.2 - 3.7

0 = 5x + 8.5

Subtract 5x from both sides:

-5x = 8.5

x = 8.5 / -5

x = -1.7.

  a.  40

  b.  0

  c.  50

Step-by-step explanation:

a) 46 + (-2k) for k = 3 is ...

  46 + (-2(3)) = 46 -6 = 40

__

b) 46 + (-2k) for k = 23 is ...

  46 + (-2(23)) = 46 -46 = 0

__

c) 46 + (-2k) for k = -2 is ...

  46 + (-2(-2)) = 46 +4 = 50
