I've provided a screenshot below. In the question, I don't understand why it can't be D. Like both C and D have the same slope,

y= 2/3x. The only difference is what comes after for those two. So why is it y=2/3x -12 and not y= 2/3x +1 ???

Choice C is the only equation with slope 2/3, while choice D has slope -2/3. This subtle difference is enough that the two lines are not parallel. The positive slope line goes uphill when moving to the right. The negative slope line goes in the opposite direction: it goes downhill when moving to the left.

The graph is below comparing the original equation with choices C and D. I used GeoGebra to make the graph, but you could use any other tool you want (eg: Desmos).

Answer:

y = 2/3x - 12 is correct

Step-by-step explanation:

D is incorrect because the slope is -2/3

To have a parallel line, you have to have the some slope, but a different y- intercept

Ill graph y = -2/3x + 1 and y = 2/3x + 5/6 and show you:

If my answer is incorrect, pls correct me!

What is 8/6 divided by 5/4?
34kurt

Answer:

1 \frac{1}{15}

Step-by-step explanation:

<em>Hey there!</em>

<em />

Well when dividing fractions you need to use Keep, Change, Flip.

\frac{8}{6} / \frac{5}{4}

Keep, Change, Flip

\frac{8}{6} * \frac{4}{5}

\frac{32}{30}

Simplified

16/15

1 \frac{1}{15}

<em>Hope this helps :)</em>

Write the equation of a line that contains (2,−2) and perpendicular to another line with slope −1.
Reika [66]

Answer:

y = x - 4

Step-by-step explanation:

Perpendicular slope = 1

y + 2 = 1 (x - 2)

y + 2 = x - 2

y = x - 4

An advertising agent goes on vacation to three countries, India, New Zealand and Australia. He spends three times the number of
Arte-miy333 [17]

Answer: 7 days.

Step-by-step explanation:

Let the number of days agent spent in Australia be x.

Then, Number of days he spent in New Zealand = 3x

and number of days he spent in India = x+5

According to the question we have the following eqauation,

x+3x+x+5=40\\\\\Rightarrow\ 5x+5=40\\\\\Rightarrow\ 5x=40-5\\\\\Rightarrow\ 5x=35\\\\\Rightarrow\ x=\dfrac{35}{5}=7

Hence, he spent 7 days in Australia.

Ishi bought a canvas and 6 tubes of paint for $24.45. If the canvas cost $6.45, what equation would represent this problem?
DedPeter [7]

$24.95−$6.95=$18. Thus 8 tubes of paint cost $18.

$188=$2.25 for 1 tube of paint.

Explanation:

Once you remove the cost of the canvas from the total price, you're left with only the cost of the 8 tubes of paint.

This is represented by

$24.95−$6.95=$18

If 8 tubes of paint cost $18, then all we have to do is divide 18 by 8 to get the cost of each individual tube of paint.

Thus

$188=$2.25

is the cost for one tube of paint.

Hope this is helpful to you..

Answer:

4. 17  

5. 28

Step-by-step explanation:

4. This shape can be broken up into a square and two identical triangles.

The area of a square is A=S*S

The side length of the square is 3

So the area of the square is:

A = 3 * 3

A =  9

The area of the triangle is A=(1/2)B*H

The height is 4 and the base is 2

So the area of the triangle is:

A =(1/2) * 2 * 4

A= 4

To get the total area we add the values.  Since there are two triangles, we will add the triangle area twice.

So the total area is

A = 9 + 4 + 4

A = 17

The area is 17.

5. We can split the shape into two triangles and calculate the area like that.  

Remember the area of a rectangle is

A = L*W

Area of the first triangle is

A = 4 * 5

A = 20

The area of the second triangle is

A = 4 * 2

A = 8

So the total area is 28

I dont feel like doing the rest of the problems, but the process is similar.
