To solve for x, we can first distribute the 3 to both terms inside the parentheses:
2x - 31 = 3x + 6
Next, we can move the 3x term to the left side of the equation by subtracting 3x from both sides:
2x - 3x - 31 = 3x - 3x + 6
Simplifying further, we have:
-x - 31 = 6
To isolate x, we can add 31 to both sides:
-x - 31 + 31 = 6 + 31
-x = 37
Finally, we can multiply both sides by -1 to solve for x:
(-1)(-x) = (-1)(37)
x = -37
So, the solution to the equation is x = -37.

Find the range of the function f(x) = 4x – 1 for the domain {–1, 0, 1, 2, 3}.
(1 point)
{–5, –3, 0, 7, 11} {–5, –4, –3, –2, –1} {–11, –7, –3, 1, 5} {–5, –1, 3, 7, 11}
(1 point)
{–5, –3, 0, 7, 11} {–5, –4, –3, –2, –1} {–11, –7, –3, 1, 5} {–5, –1, 3, 7, 11}
To find the range of the function f(x) = 4x - 1 for the given domain {-1, 0, 1, 2, 3}, we need to substitute each value from the domain into the function and find the corresponding output.
When x = -1:
f(-1) = 4(-1) - 1 = -5
When x = 0:
f(0) = 4(0) - 1 = -1
When x = 1:
f(1) = 4(1) - 1 = 3
When x = 2:
f(2) = 4(2) - 1 = 7
When x = 3:
f(3) = 4(3) - 1 = 11
The outputs for each value in the domain are {-5, -1, 3, 7, 11}.
Therefore, the range of the function is {–5, –1, 3, 7, 11}.
When x = -1:

To find the slope of the graph of the equation 9x - 3y = 15, we need to rewrite the equation in slope-intercept form, which is in the form y = mx + b, where m represents the slope.
Let's start by moving the 9x term to the right side of the equation:
-3y = -9x + 15
Next, we can divide both sides of the equation by -3 to solve for y:
(-3y)/-3 = (-9x + 15)/-3
Simplifying further, we have:
y = 3x - 5
Comparing the equation to y = mx + b, we can see that the slope, m, is 3.
Therefore, the slope of the graph of the equation 9x - 3y = 15 is 3.
Let's start by moving the 9x term to the right side of the equation:
-3y = -9x + 15
Next, we can divide both sides of the equation by -3 to solve for y:
(-3y)/-3 = (-9x + 15)/-3
Simplifying further, we have:
y = 3x - 5
Comparing the equation to y = mx + b, we can see that the slope, m, is 3.
Therefore, the slope of the graph of the equation 9x - 3y = 15 is 3.
What is the slope-intercept form of the equation 4x + 2y = 6? (1 point)
y = 2x + 3 y = 2x – 3 y = –2x – 3 y = –2x + 3
y = 2x + 3 y = 2x – 3 y = –2x – 3 y = –2x + 3
To find the slope-intercept form of the equation 4x + 2y = 6, we need to solve for y.
First, let's isolate the term with y by moving the 4x term to the right side of the equation:
2y = -4x + 6
Next, divide both sides of the equation by 2 to solve for y:
(2y)/2 = (-4x + 6)/2
Simplifying further, we have:
y = -2x + 3
Therefore, the slope-intercept form of the equation 4x + 2y = 6 is y = -2x + 3.
First, let's isolate the term with y by moving the 4x term to the right side of the equation:
2y = -4x + 6

Simplifying further, we have:
y = -2x + 3
Therefore, the slope-intercept form of the equation 4x + 2y = 6 is y = -2x + 3.
