-4y+ 5x= 17
The point (x, -3) is a solution to the equation shown. What is the value of x?

Answers

Answer:

x = 1

Step-by-step explanation:

Given

- 4y + 5x = 17 and (x - 3) is a solution

Substitute y = - 3 into the equation and solve for x

- 4(- 3) + 5x = 17

12 + 5x = 17 ( subtract 12 from both sides )

5x = 5 ( divide both sides by 5 )

x = 1

Solution is (1, - 3 )

Answer:

x = 1

Carly is traveling to visit family. She drives x miles on the first day and y miles on the second day for a total of 800 miles. What are the domain and range of this relationship?

Answers

Answer:

The domain and range of this relationship is (-∞,∞) and (-∞,∞) respectively.

Step-by-step explanation:

We are given that Carly is traveling to visit family.

She drive distance on first day = x

She drive distance on second day = y

We are also given that Carly is travelling a total of 800 miles.

So,x+y=800

We are supposed to find domain and range of this relationship.

y=800-x

Domain : (-∞,∞)

Range:(-∞,∞)

Hence the domain and range of this relationship is (-∞,∞) and (-∞,∞) respectively.

Answer:

domain: 0 ≤ x ≤ 800

range: 0 ≤ y ≤ 800

(HELP ME PLEASE!!!!!! IT HAS PICTURES!!!!!)The edge of each cube used to build this rectangular prism is 1/3 inch long. Which equation shows the volume of the prism, in cubic inches?|A|(9/3⋅6/3⋅6/3) in.^3 = 12 in.^3

|B|(3/3⋅2/3⋅3/3) in.^3 = 2/3 in^.3

|C|(3 1/3⋅2 1/3⋅3 1/3) in.^3=25 25/27 in.^3

|D|(3⋅2⋅3) in.^3=18 in.^3

Answers

Answer:

Option B

Step-by-step explanation:

step 1

Find the number of cubes in the prism

$(3)(2)(3)=18\ cubes$

step 2

Find the volume of one cube

The volume of one cube is equal to

$V=b^3$

where

b is the length side of the cube

we have

$b=(1)/(3)\ in$

substitute

$V=((1)/(3))^3$

$V=(1)/(27)\ in^3$

step 3

To find out the volume of the prism , multiply the volume of one cube by the number of cubes

$V=((1)/(27))18$

$V=(18)/(27)\ in^3$

simplify

$V=(2)/(3)\ in^3$

Answer:

|B|(3/3⋅2/3⋅3/3) in.^3 = 2/3 in^.3

Explain how you know that 7/12 is greater than 1/3 but less than 2/3

Answers

To compare, all denominators must be the same. So, find the common denominator for 12,3&3, which is 12 (12x1=12, 3x4=12). Whatever you do for the bottom you must also do for the top. So, 7x1/12x1= 7/12, 1x4/3x4=4/12, and 2x4/3x4=8/12. Therefore 7/12 is greater than 1/3 (AKA 4/12) but less than 2/3 (AKA 8/12).

the denominators have to be the same that's the short way to say what she said
