Leah is writing an equivalent equation which solves for y. What should be her next step? 3 x + 4 y = 8. 3 x minus 3 x + 4 y = 8 minus 3 x. 4 y = 8 minus 3 x.
Given :
A linear equations :
3x+4y = 8 .
She have completed the following steps :
3x+4y = 8
3x+4y-3x = 8-3x
4y = 8 -3x
To Find :
The equivalent equation which solves for y.
Solution :
General equation of line or equation which solves for y is given by :
y = mx +c
So , our next step should be dividing both sides by 4 .
[tex]\dfrac{4y}{4}=\dfrac{8}{4}-\dfrac{3x}{4}\\\\y=2-\dfrac{3x}{4}[/tex]
Therefore , equation which solves for y is [tex]y=2-\dfrac{3x}{4}[/tex] .
Hence , this is the required solution .

Write the following equations in slope intercept form
Equation 1: y-7x=6
Equation 2: y+7x=8
Answer:
Equation 1: y = 7x + 6
Equation 2: y = -7x + 8
Step-by-step explanation:
Isolate the y variables in both equations
Equation 1:
y - 7x = 6
y = 7x + 6
Equation 2:
y + 7x = 8
y = -7x + 8
So, the equations in slope intercept form are:
Equation 1: y = 7x + 6
Equation 2: y = -7x + 8

If m angle 5 = 42 degrees and m angle 1 = 117 degrees, find m angle CDF
Answer:
its 159
Step-by-step explanation:
The angle CDF is 159 degrees
Using this formula to determine angle CDF
Angle CDF=m angle 1+ m angle 5+
Where:
m angle 1=117 degrees
m angle 5=42 degrees
Let plug in the formula
Angle CDF=117 degrees+42 degrees
Angle CDF=159 degrees
Inconclusion the angle CDF is 159 degrees

Luis does chores at home to earn extra money. Each week he earns $20. He already has $320 in his savings account, and is trying to save up to buy a new iPhone X for $930. How many weeks will it be until he can buy the new iPhone?
Answer:
30.5 Weeks
Step-by-step explanation:
The phone costs $930, and he already has $320 saved in his bank account so subtract 320 from 930. You will get 610. Then, you take 610 and divide it by 20 because he earns $20 a week. I hope this helped.

Find the following lengths.
X=_____
BC=10
Answer:
see explanation
Step-by-step explanation:
Since B is the midpoint of AC, then
AB = BC , substitute values
3x - 5 = x + 5 ( subtract x from both sides )
2x - 5 - 5 ( add 5 to both sides )
2x = 10 ( divide both sides by 2 )
x = 5
Thus
BC = x + 5 = 5 + 5 = 10

1. For the equation, x-7 = 24. can a value be substituted for x to make that a true
number sentence? How many values could be substituted for x and have a true
number sentence?
Answer:
The value 31 can be substituted for x. Only the value 31 can be substituted.
Step-by-step explanation:
So to solve a one step equation the goal is to isolate the variable. As you can tell from we are subtracting the 7. The opposite of addition is subtraction so we want to add the 7. -7 plus a positive 7 is 0 which cancels it out. Now we have x=24. However what you do to one side you need to do to the other. So we add 7 to the 24. 7+24 is 31. Therefore 31 can be substituted for x. Lets check out answer. What is 31-7? 31-7 is 24. Now we know our work was correct
