x+47=-23
move +47 to the other side to get x by itself
sign changes from +47 to -47
x+47-47=-23-47
x=-23-47
x=-70
answer: x=-70
Answer:
Step-by-step explanation:
We want to find the equation of the line that includes the points (7, -7) and (0, 3).
First, we will find the slope of the line using the slope formula given by:
So, the slope of our line is:
Next, notice that the given point (0, 3) is our y-intercept.
Slope-intercept form is given by:
Where m is the slope and b is the y-intercept.
Therefore, by substitution, we acquire that our equation is:
Answer: x=-5
Step-by-step explanation: In order to get rid of the parentheses we must multiply or distribute the outside number times anything inside the parentheses.
–5(1 – 5x) + 5(–8x – 2) = –4x – 8x
-5-25x+-40x-10=-4x-8x
Next we combine like terms.
-5-25x+-40x-10=-4x-8x
-15-15x=-12x
Then we add 15x to both sides
-15-15x=-12x
-15=3x
Finally we divide both sides by 3 which will give us our answer.
-15=3x
-15/3=3x/3
x=-5

Answer:
is rational number
Step-by-step explanation:
Rational number is of the form p/q, where q ≠ 0. It may be a terminating number or non terminating repeating number.
√2 is irrational number as it is non terminating non repeating number
π is irrational number as it is non terminating non repeating number
√10 is irrational number as it is non terminating non repeating number.
is a rational number
The answers are A C and E because all functions are linear equations and it is positive and would go up on a graph and goes up at a constant rate of 350. Hope this helps
