Find the perimeter and area of the image after dilating the figure shown with the given scale factor.

Answers

im pretty sure it’s:

p’ = 12(5)=60

a’ = 9(5^2)=225

you probably don’t have to include the equation, but i wanted to put it in there just in case :-)
When asking for you to change to scale factor, it means that the shape is going to be 5x the shape, therefore, simply multiply the perimeter and area by 5, P = 60 A = 45

Answer:

4 feet

Step-by-step explanation:

The height of the tower when she will finish is 4 feet.

What is an expression?

The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.

Given that Priya is stacking building blocks to make a tower. She takes a break when the tower is 2¹/₂ feet tall, which is 5/8 of the height of the tower she wants to build.


The height of the tower will be calculated as,

5 / 8 x = 2¹/₂

x = ( 8 / 5 ) x 2.5

x = 4 ft

4x=3y-2 in slope intercept form
explain

Answers

Answer:

y = 4 /3 x  +  2 /3

Answer:

y = -4/3x - 2/3

Step-by-step explanation:

The slope intecept form is y = (slope)x - (some #).

So, turning 4x = 3y - 2 into the slope intercept form, we get:

4x = 3y - 2

3y = -4x - 2

y = -4/3x - 2/3

Answers

Answer:

84 cubic feet

Step-by-step explanation:

First, multiply the numbers to get the volume.

5 2/5 * 4 2/3= 25 1/5

25 1/5 * 4 4/9= 112

Then, we can find 3/4 of that.

112*3/4=84.

The answer is 84 cubic feet

a linear function passes through the points (10,5) and (-15, -5). a second function is represented by the equation 4x-3y= 6 what is the y-intercept of the function with the greater rate of change HELP DUE IN 5

Answers

Answer:

-2 is y-intercept

Step-by-step explanation:

If a linear function passes through the points (10,5) and (-15,-5), then the slope of it must be 2/5.

This is because the formula to find slope is  (y2-y1 / x2-x1), which in this case, when the values are input, equal to 2/5.

When finding the slope of 4x-3y=6, we need to rewrite the equation in slope-intercept form, causing the original equation to become y=4/3x-2. In this case, 4/3x symbolizes the slope (4/3).

Seeing as 4/3 > 2/5, we will consider the y-intercept of 4x-3y=6 as the correct answer.

Subsitute x for 0:

4(0)-3y=6

= -3y=6

Divide both sides by -3:

-3y/3 = 6/-3

= (y = -2)

Therefore, the correct answer is -2, the y-intercept of the equation 4x-3y=6.
