help me please I'm nice :)

Explanation:

Each term inside is raised to the fourth power.

The rule is (ab)^c = a^c*b^c

An example:

(2*3)^4 = 6^4 = 1296

(2*3)^4 = 2^4*3^4 = 16*81 = 1296

Therefore, (2*3)^4 = 2^4*3^4

Answer:

AB = 10

EF = 2

Step-by-step explanation:

to find the scale factor you have to divide the bigger scale by the smaller one which would be

(5x)/5    and   4/x

since both scale factors should be the same you can set them even to each other

(5x)/5=4/x

solve for x

(5x)/5=4/x

x=4/x

x^2=4

x=2

Answer:[tex]\frac{2}{3}[/tex]

Step-by-step explanation:

you can take 2 points (for example (0,-3) and (3,-1)) and use rise over run ([tex]\frac{x_{2} -x_{1} }{y_{2}-y_{1} }[/tex]) to find the slope, and just plug them into rise over run

Answer:

D. the length is 18 inches and the width is 9 inches.

Step-by-step explanation:

Given information:

Therefore, to find the actual dimensions of the lawn, multiply the given scale dimensions by 15:

⇒ Length = 6 × 15 = 90 in

⇒ Width = 3 × 15 = 45 in

If the gardener's partner plans to make another scale drawing of the lawn with a different scale of 1 : 5, to find the dimensions of his scale drawing, divide the actual dimensions by 5:

⇒ Length = 90 ÷ 5 = 18 in

⇒ Width = 45 ÷ 5 = 9 in

Therefore, the dimensions of his scale drawing are the length is 18 inches and the width is 9 inches.

An alternative way to approach this problem is to calculate the difference between the two scales.  It is clear that the original scale of 1 : 15 is 3 times the new scale of 1 : 5.  Therefore, simply multiply the original dimensions by 3 to find then new dimensions of the scale drawing with a scale of 1 :5.

Answer:

15

Step-by-step explanation:

3/7 = m/35

7 x ? = 35

7 x 5 = 35

so 3 x 5 = 15

For this equation the easiest thing to start with ratios:

16:4 (scale of 4 due to 4 x 4 being = to 16)

For the y-2 to find y you first will put 8/4 (your scaling back), so 2 so 4-2 would be 2 which makes that equal to y.

Knowing that 8 is the size on the one side these are equal on the top so x-3 had to equal 8, so 11-3=8 so...

x=11

y=2

Answer:

17+1+1

Step-by-step explanation:

Answer:

The longest side can be anything but the number of the longest side has to be less than the other 2 sides after you add them together.

example:    The longest side can be 9 and the other 2 sides are 5. When you add them both together they equal 10 which is more than 9 so it would work.

Answer:

QR and CD, both are located at the same part of both shapes

First step, make ratios:

Pages: time

Sheldon: 9 pages: 15 minutes

Betty: 18 pages: 60 minutes (1 hour)

To find how long it would be for 360 you divide:

9/15 is 0.6 pages: 1 minute and 18/60 is 0.3 pages per minute

When you make the table here would be the equation:

y=.06x for Sheldon and y=.3 for betty (plug in times and create a table)

Answer: 14

Step-by-step explanation:

Answer:

not similar

Step-by-step explanation:

Answer:

Step-by-step explanation:

I would say not similar because they both don't have the same length and width but if you're talking about the shape itself then I would say similar because they are both quadrilaterals and trapezoids.

Answer: 10

Step-by-step explanation: The answer is 10 because xy means x times y, and since x = 10 and y = -2, 10 times -2 equals -20. Now you have to divide that by --2 which is just 2. So -20/2 equals -10. -10's absolute value is 10. Thus the answer is 10.

Answer:

a = 8

Step-by-step explanation:

Write the equation:

7/a = 35/40

Divide:

7/a = 35/40

7/a = 35 ÷ 40

7/a = 0.875 (convert back to a fraction)

7/a = 7/8

Multiply:

8a • 7/a = 7/8 • 8a

8 • 7 = a • 7

56 = 7a

Divide to get answer:

56/7 = 7a/7

8 = a

a = 8

Answer:

y=4x

Step-by-step explanation:

if you look at the line you'll see it takes 4 x's to = 1 y, every time you go right 1 you go up 4

Answer:

The slope is 4.

Step-by-step explanation:

Step 1:

Slope can also be found by using the formula, Y2-Y1/X2-X1

In this case, our first point is the origin, so x would be 0 and y would be 0. On the second point, our x is -1, and our y is -4.

So, we can make the solution, -4-0/-1-0.

You can simplify this into, -4/-1, and then into 4.

Therefore, the slope is 4.

Step 2:

M is our slope, so in our y=mx equation our m = 4.

If you substitute in the m, you get y=4x.

Answer:

y=4x.

Hope this helped!

Answer: slope = 1/2

Step-by-step explanation:

(y2 - y1) / (x2 - x1) = m

(4 - 3) / (6 - 4) = m

m = 1/2

slope = 1/2
