Answer:
x = 10
Step-by-step explanation:
It says they equal each other so equal the two separate expressions together
-2x + 30 = 2x - 10
goal is to isolate variable x
add 2x to both sides (this cancels out the -2x on the left side)
30 = 4x - 10
add 10 to both sides (this cancels out the -10 on the right side)
40 = 4x
divide 4 by both sides (cancels out 4 on the right side)
10 = x
-(x + 3) + 3/4x +5= 0

How do solve this equation
Answer:
x=6
Step-by-step explanation:
3x-6=12
+6 +6
3x=18
3x/3= 18/3
x=6
Hope this helps!
Answer:
x=6
Steps
3x - 6 = 12
add 6 to both sides
3x - 6 + 6 = 12 + 6
simplify
3x = 18
Divide both sides by 3
3x/3 = 18/3
simplify
x=6

Step-by-step explanation:
Xavier buys 4 snacks and
2 cans of soda. Each
snack costs $1.25, and
each can of soda costs s
dollars. Xavier's total for
the snacks and soda was
$8. How much did each
can of soda cost?
Answer: Each can of soda costed $1.50
Step-by-step explanation:
The total cost was $8
Xavier's bought 4 snacks; each $1.25
4 x 1.25 = $5
How much for 2 cans of soda?
Well we know how much the snacks were ($5) and the total cost was $8, so the 2 cans costed $3 because 5 + 3 = 8. But how much did each can cost? Each can costed $1.50 because if the 2 cans costed $3, and we wanted to know how much 2 costed, we would have to divide 3 by 2 which is 1.50. So each can costed $1.50

The linear parent function,f(x)=x ,was transformed to create a graph g(x)=−f(x).
Which statement about the graph is true?
The graph of f is reflected over the x-axis to create the graph of g.
The graph of f is shifted 1 unit down to create the graph of g.
The graph of f is shifted 1 unit left to create the graph of g.
The graph of f is shifted 1 unit right to create the graph of g.
Answer:
The graph of f is shifted 1 unit down to create the graph of g.
Step-by-step explanation:
i took the test earlier and got this answer
The linear parent function f(x) = x is reflected over the x-axis to create the grap of g(x) = - f(x).
What is translation?There are four different kinds of translation: stretching, shrinking, rotating, and shifting.
When shifting, the entire graph is moved in the XY direction. When expanding and contracting a graph, we do so by a factor of k. When rotating a graph, we do so either clockwise or counterclockwise.
We know that when we change the sign of x in a function it is rotated about
the y-axis and when we change the sign of y in a function it is rotated about the x-axis.
f(x) = y = x and g(x) = - f(x) = - y.

If the equation of a line is y= - 2/3 x - 2 at what.point on the graph would I find the y- intercept?
Answer:
(0, -2)
Step-by-step explanation:
The slope equation is written as y = mx + b where m is the slope and b is the y-intercept. In this equation the slope, which is m, is -2/3 and the y-intercept is -2, which is the value of b. So the y-intercept on the graph would be found at point (0, -2)
Let y = mx +b, where m is the slope of the equation and b is the y-intercept.
So from the equation [tex]y=-\frac{2}{3}x-2[/tex] You'd find the y-intercept at (0,2). Alternative way, you can find the y-intercept by substituting x = 0 so -2x/3 will be 0 because x = 0 and -2x(0)/3 = 0-2 = -2.
So from the y = mx + b, you would find the y-intercept at (0,b)

What is the solution to
5 + 3(x - 1) = 3x + 14 - (x +15)
Answer:
x = -3
Step-by-step explanation:
5 + 3(x - 1) = 3x + 14 - (x +15)
5 + ( 3x - 3 ) = 3x + 14 - x -15
3x + 2 = 2x - 1
x + 3 = 0
x = -3
Answer:
x = -3
Step-by-step explanation:
To find the solution to the equation, we would have to find a value of x that would satisfy the equation.
5 + 3(x - 1) = 3x + 14 - (x + 15)
Distribute the 3 on the left side and the - on the right side.
5 + 3x - 3 = 3x + 14 - x - 15
Combine like terms.
2 + 3x = 2x - 1
Subtract 2 from both sides.
3x = 2x - 3
Subtract 2x from both sides.
x = -3
So the solution to the equation would be x = -3.
