For this case we must raise the equation according to the given statement.

Let the variable "x" be the unknown number.

So, three times the number is: $3x$

If to that term is added "6" we have:

$3x+6$

The sum of both terms is "12", then:

$3x+6 = 12$

Thus, the equation is: $3x+6 = 12$

Answer:

$3x+6 = 12$

X +y=5, 3x-2y+5=0, this is the question

Neko [114]

Step-by-step explanation:

x+y=5

3x-2y+5=0

3x-2y= -5

x+y=5...... equation 1

3x-2y= -5....... equation 2

there fore make x the subject of the formula in equation 1

x=5-y.. equation 3

substitute equation three in equation 2

3(5-y)-2y=-5

15y-3y-2y=-5

10y=-5

divide both sides by 10

y=-5/10

y=-½

substitute y into equation 1

x+(-½)=5

x=5+½

x=5½

x=5½,y= -½

A rectangular prism has a length of 212 centimeters, a width of 212 centimeters, and a height of 5 centimeters. Justin has a sto

BlackZzzverrR [31]

Answer:

$3.75\ cm^{3}$ or $3\frac{3}{4}\ cm^{3}$

Step-by-step explanation:

step 1

Find the volume of the rectangular prism

we know that

The volume of a rectangular prism is

$V=LWH$

In this problem we have

$L=2\frac{1}{2}\ cm=\frac{2*2+1}{2}=\frac{5}{2}\ cm$

$W=2\frac{1}{2}\ cm=\frac{2*2+1}{2}=\frac{5}{2}\ cm$

$H=5\ cm$

substitute in the formula

$V=(\frac{5}{2})(\frac{5}{2})(5)=\frac{125}{4}=31.25\ cm^{3}$

step 2

Find the difference between the volume of the prism and the volume of the storage container

$35\ cm^{3}-31.25\ cm^{3}=3.75\ cm^{3}$

$3.75=3\frac{3}{4}\ cm^{3}$

2. Alicia is writing the program for a video game. For one part of the game she uses the rule to move points on the screen.

Gwar [14]

Complete Question:

Alicia is writing the program for a video game. For one part of the game she uses the rule (x,y)->(x-3,y+4) to move points on the screen.

A) what output does the rule give when the input is (-6,0)?

B)What output does the rule give when the input is (3,-4)?

C) Is the rule a function? Explain why it is or why it is not

Answer:

a. The output is (-9,4)

b. The output is (0,0)

c. See Explanation

Step-by-step explanation:

Given

Rule: (x,y)->(x - 3, y + 4)

Solving (a):

Inputs:

$x = -6$

$y = 0$

The outputs is as follows;

$x => x - 3$

$x => -6 - 3$

$x => -9$

$y=> y + 4$

$y=> 0 + 4$

$y=> 4$

Hence:

The output is (-9,4)

Solving (b):

Inputs:

$x = 3$

$y = -4$

The outputs is as follows;

$x => x - 3$

$x=>3-3$

$x = 0$

$y=> y + 4$

$y=>-4+4$

$y=>0$

Hence:

The output is (0,0)

Solving (c):

The function is a rule and the rule is that:

It shifts the graph left by 3 units and up by 4 units
