Can someone explain dilations to me?

Answer:

$2.22

Step-by-step explanation:

You divide $20 by 9

Answer:

120 miles in 2 hour

Step-by-step explanation:

One hour has 4 times 15 minutes, so you need to do 15 miles x 4 and that time 2 because its 2 hours.

Answer:

c

Step-by-step explanation:

slope is 3 and y intercept is -10 so y=3-10

Answer:

translation -(-7, -4)

Answer:

X = 9

Step-by-step explanation:

Answer:

Step-by-step explanation:

The two sides add up to 12. If the third "side" of the triangle is 12, then 5 and 7 will lie horizontally on 12.

So the maximum value must be less than 12. What's the smallest x could be?

well 5 + something must be > than 7. If they are not larger than 7, then 5 and something will lie on 7 just as it did before. So how big is something?

5 + y > 7

5 - 5 + y > 7 - 5

y > 2

So the range    is  2 < x < 12

How else could you write this?

2 < x

x < 12 is one way.

Answer:

$3,250

Step-by-step explanation:

You take the initial fee of 250 then add 75x40

250x75(40)=$3250

Answer:

A

Step-by-step explanation:

all triangles equal 180°, it gives you two angles on each triangles. if you add them together and subtract that from 180 you'll get the final angle. the angles on both triangles Are 45,63, and 72. (they add up to 180) and because both triangles have two angels that are the congruent. they are similar by the Angle angle postulate.

How do you except me to know

Step-by-step explanation:

Bruh I came here to find the Awnser not to actually work for it

Answer:

constant

Step-by-step explanation:

3 is the coefficient, b is the variable, 4 and 7 are the constants.

Answer:

The transformation is 0.5

Step-by-step explanation:

The lengths of the second triangle is just half the length of the first triangle, from the center. As it is just resizing, the angles would not change, resulting in the same triangle, except for size.

Answer:

3x

Step-by-step explanation:

Combine like terms: 5-2=3, so 5x-3x=2x.

Hope this helps plz mark brainliest :D

Answer:

x= 23

Step-by-step explanation:

180 minus 3 is 87

3 times 23

87

Answer:

The slope is 3

y-intercept is -16

Step-by-step explanation:

Let's start by using the slope formula, [tex]m=\frac{y2-y1}{x2-x1}[/tex]

plug in the points for the relating x and y and solve,

[tex]m\frac{5-2}{7-6}[/tex]   this simplifies to [tex]\frac{3}{1}[/tex]  or "3"

we have our slope: 3/1 or "3"

the equation needed to find the y-intercept is y=mx+b

We will need to solve for "b" to figure out the y-intercept.

let's plug in any pair of x and y, i'll just choose (6,2)

2=3(6)+b,   2=18+b,    2-18=18-18+b,     -16=b  

Y-intercept is -16

Answer:

0.46666666666...

Step-by-step explanation:

divide 7 by 15 :/

Answer:

.4666666666...

Step-by-step explanation:

7/15

to get 7/15 to a decimal you want to divide 7 by 15

7/15 = .466666...

Answer:

144

Step-by-step explanation:

1872 divided into bags with 13 each is

1872/13= 144 bags to fill

Answer:

Step-by-step explanation:

Given

Natoy's rectangular swimming pool has the length of 3m more than thrice its

width.

Width=w

Length =3w+3

So

Area of the rectangular swimming pool=length×width

216=(3w+3)×w

216=3w^2+3w

3w^2+3w-216=0

3(w^2+w-72)=0

W^2+w-72=0

W^2+(9-8)w-72=0

W^2+9w-8w-72=0

W(w+9)-8(w+9)=0

(W+9)(w-8)=0

Sotwo value of w are 8,-9

We take positive value for rectangular swimming so we take w=8m

Width=8m

Length=3×8+3

= 24+3

=27m

Answer:

Zeros are at x=0 and x=3/2.

Step-by-step explanation:

f(x) = x(6x - 9)

x=0 and 6x -9 = 0

6x = 9

x = 3/2

Answer:The vertex is

(0,7)

Sometimes we have problems with the easier questions because it's not exactly in the form we're used to. Normally for a quadratic, you would complete the square to find the vertex. But this quadratic is already in vertex or standard form:

f(x)=−(x−0)2+7

Step-by-step explanation: Hope this helps

Answer:

Option 2

Step-by-step explanation:

[tex]2 \frac{2}{13} + \frac{15}{13} =[/tex] [tex]2 \frac{2}{13} + 1 \frac{2}{13} = 3 \frac{4}{13}[/tex]

Answer: The answer is option 2. 3 4/13

Step-by-step explanation:

2 2/13 + 15/13 =  2 17/13

17 fits into 13 one time and you're left with 4/13 as a remainder.

Since 17 was able to fit into 13 at least once, you get another whole number making your already existing whole number of 2 into 3.

Thus your answer is 3 4/13. I hope this was a helpful explanation! :)

Answer:

7 to the 7th power

Step-by-step explanation:

To get your answer you add your two exponents together and that becomes your new exponent. Your base number stays the same..

The answer is 7 ⁷

Step-by-step explanation: 7 ⁴ is 343 and 7 ³ is 2401 so if you multiply those together it is

823,543. 7 ⁷ in total is 823,543

Answer:

What you need to do is to find a multiple of 20 and 16 in other words a number that can multiply into 20 and 16. You have 2 and you have 4. So now this is how it looks like.

Either:

4(5+4) Or

2(10+8)

Step-by-step explanation:

Answer:

[tex]y\leq 4[/tex]

Step-by-step explanation:

Start with the given

[tex]2y\leq 8\\[/tex]

Divide the two on both sides to get

[tex]y\leq 4[/tex]

Answer:

y=≤4

Answer:

DE = 15, AB = 6

Step-by-step explanation:

Because the triangles are similar, that means that the sides are proportional to each other. The ratio of CE to AC is 24/8 which is 3. That means that each length of the small triangle is 3 times smaller than the same side on the larger triangle.
