Triangle ABC is graphed on a coordinate plane with vertices at A(-3, 7), B(9,-8), and C(-5, -6). If triangle ABC is dilated
by a scale factor of 2 with the origin as the center of dilation to create A'B'C', what will be the coordinates of the dilated
vertex of B'?

Answers

Answer:

  B' = (18, -16)

Step-by-step explanation:

Dilating means to stretch or shrink a figure. The scale factor tells us how much we are stretching or shrinking. The scale factor is 2, so the coordinates are multiplied by 2.

Answer: 1.25m + 3 ≤ 18; Antonio can ride 12 or fewer miles

Step-by-step explanation: so you can break down the answer choices and only have a and b left because no more than means this sign: ≤

and 1.25 is the cost for each mile so your multiplying m and 1.25 and then you add that with 3.

Can anyone give me the awnser?​

Answers

Answer:

Step-by-step explanation:

You want to reverse the algebra and solve for y. First you want to subtract the 'a' to both sides.

x - a = -2by^2

Divide by -1 on both sides

-x + a = 2by^2

Divide by 2b on both sides

(-x + a)/2b = y^2

Take the square root of both sides

[tex]\sqrt{(-x+a)/2b}=y[/tex]

A shirt costs $19 you buy it on clearance for 40% off. How much did you pay for the shirt?
Please explain how to find the answer and please answer fast...Thank you
PLEASE HELP

Answers

answer: $11.40

explanation: turn the percent into a decimal, multiply it by the starting cost, then subtract the product from the starting cost

>> 40% = 0.40

0.40 x 19 = 7.60

19 - 7.60 = 11.40

You paid $11.4 for the shirt.

What is a percentage?

A ratio or value that may be stated as a fraction of 100 is called a percentage. And it is represented by the symbol '%'.

Given:

A shirt costs $19 you buy it on clearance for 40% off.

You paid,

= 19 - (19 x 40 / 100)

= 19 - 7.6

= $11.4

Therefore, the amount is $11.4.

A new soft drink has 20% less sugar than before.
The drink had 50 grams of sugar originally.
How much less sugar does it have now?

Answers

20% of 50 is 10 (50 x .20 = 10). If the original drink had 50 grams, and the new one has 20% (10 grams) less...then the new drink would have 40 grams of sugar (50-10=40).

The required amount of sugar is given as 40 grams.

Given that,
A new soft drink has 20% less sugar than before. The drink had 50 grams of sugar originally, how much less sugar it has now is to be determined.

What is simplification?

The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.
