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 .
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

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

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

Step-by-step explanation:
A factor of n is a number which when multiplied by another number gives us the number n. The expression that can not be simplified is √38.
What is a factor?A factor of n is a number which when multiplied by another number gives us the number n.
The given expression can be simplified as shown below.
√24 = √(3×2×2×2) = 2√6√32 = √(2×2×2×2×2) = 4√2√27 = √(3×3×3) = 3√3√38 = √(2×19), since there are no common factors, therefore, √38 can not be simplified.Hence, the expression that can not be simplified is √38.

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
