Answer:
= 6/7x+2
Step-by-step explanation:
just remove the parenthesis and combine like terms.
i hope this helps :)
Answer:
Step-by-step explanation:
Combine like terms.
2/7x and 4/7x are like terms
5 and -3 are like terms
[tex](\frac{2}{7}x + 5) + (\frac{4}{7}x - 3) = \frac{2}{7}x+ \frac{4}{7}x + 5 - 3\\\\\\ = \frac{2+4}{7}x+ 2 \\\\= \frac{6}{7}x+2[/tex]

A function g models a relationship in which the dependent variable doubles for every 3 units the independent variable increases.
Answer:
x-intercept = 3
y-intercept = -2
Step-by-step explanation:
P.S - The exact question is -
Given - A function g models a relationship in which the dependent variable doubles for every 3 units the independent variable increases.
To find - Graph g when g(0) = -2. Identify the y-intercept and x-intercept.
Proof -
By using the given information , we get
g(x) = [tex]\frac{2}{3} x - 2[/tex]
g(0) = 0 - 2 = -2
It also satisfy the condition g(0) = -2
Here,
by comparing with general form of slope-intercept form y = mx + c
where m = slope, c = y-intercept
Slope, m = [tex]\frac{2}{3}[/tex]
For x-intercept,
Put y = 0
⇒[tex]\frac{2}{3} x - 2[/tex] = 0
⇒[tex]\frac{2}{3}x = 2[/tex]
⇒x = 3
So,
x-intercept = 3
For y-intercept,
Put x = 0
⇒y = 0 - 2
⇒y = 2
∴
y-intercept = -2
Which of the equations shows an application of the Zero Property of Multiplication? A. 25+0=25 B. 13(3)= C. 0∙2=0 D. (34−2)−(34+3)=−5
Answer:
0∙2=0
Step-by-step explanation:
Zero Property of multiplication is as follows :
The product of a number and 0 is equal to 0.
In option (c), 0 is multiplied by 2 and as a result, we get 0 as the answer.
It means,
0∙2=0
Hence, option (c) i.e. 0∙2=0 shows the Zero Property of Multiplication.
420 student 25 times 3 times the number of girls 2 times the number of boys how many girls amd how many boys
Complete Question
We have a total of 420 students. 2 times 3 times the number of girls is equal to 2 times the number of boys how many girls and how many boys
Answer:
The number of boys = x = 315 boys
The number of girls = y = 105 girls
Step-by-step explanation:
Let
The number of boys = x
The number of girls = y
We have 420 students
2 times 3 times the number of girls is equal to 2 times the number of boys
x + y = 420..... Equation 1
2 × 3y = 2x
6y => 2x
x => 6y/2 = 3y
We substitute 3y for x in Equation 1
3y + y = 420
4y = 420
y =>420/4
y => 105
Solving for x
x = 3y
x = 3 × 105
x = 315
Therefore,
The number of boys = x = 315 boys
The number of girls = y = 105 girls

Answer:
(x,y) (28/19, -35/19)
hope this helps
Answer:
x = 6, y = 4
Step-by-step explanation:
multiply the equation x + 2y = 14 by two then subtract the equation 2x - 6y = - 12 to eliminate x and solve for y:
×2 => 2x + 4y = 28
-) 2x - 6y = -12
_________________
10y = 40
=> y = 4
substitute y = 4 to either of the equation 2x - 6y = - 12 OR x + 2y = 14 to solve for x:
=> 2x - 6(4) = -12
=> 2x = 12
=> x = 6

Solve 16 = 2x − 2. 2 4 6 8
Answer:
The answer to this question is 6.
Step-by-step explanation:
To find the value of x we must find what minus 2 gets us 16. To find this we pretty much just see what 2 to the power gives us 16, therefore we find that 2^4 is 16. We now must solve for x. We take all of our possible solutions and find what minus 2 gets us 4. We then can see that 6-2 is 4 and that 2^4 is 16. Therefore, we can conclude that x is equal to 6.
If the linear equation with a single variable is 2x - 2 = 16. Then the value of the variable x is 9.
What is linear system?A linear system is one in which the parameter in the equation has a degree of one. It might have one, two, or even more variables.
The linear equation with a single variable is given below.
16 = 2x - 2
Then the value of x will be given as
18 = 2x
x = 9
Then the value of the variable x is 9.

Answer:
If you were to make a 360 degree circle and minus the 50 thats already there you get 310 the right angle on angle 5 is 90 degrees because its a right angle so then the 310-90=220 the obtuse angle on angle 2 is 180 so 220-180=40 lastly you share those forty between angles 3 and 4 and the solution is your answer.

Roger is building a frame for a flower bed. He is using left-over scraps of wood from his garage. He needs a total of 12 feet of wood. The pieces he has in his garage are 314 feet, 412 feet, and 4 feet. Does he have enough wood to build the frame?
A. Yes, because 12 > 1134
B. Yes, because 1234 > 12
C. No, because 1134< 12
D. No, because 1116 < 12
Answer:
C. No, because 11.34 < 12
Step-by-step explanation:
3.14 + 4.12 + 4 has to be greater than or equal to 12
solve the equation
3.14 + 4.12 + 4 >= 12
7.26 + 4 >= 12
11.26 >= 12 is false
I don't know why it says 11.34 because the numbers don't add up, so I'll assume that there is a typo somewhere.
