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

the answer would be B
The required equivalent expression to [tex]\sqrt{-50}[/tex] is 5i√2.
Given that,
An equivalent expression to [tex]\sqrt{-50}[/tex] is to be determined.
The number that constitutes real and imaginary numbers are called complex numbers.
What is simplification?The process in mathematics to operate and interpret the function to make function simple or more understandable called simplify and the process is called simplification.
Here,

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

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
What is the slope of the function?
5 = x is the same as x = 5 due to what

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 .
