Answer:
Use the given functions to set up and simplify
Use the given functions to set up and simplify
−2.−2=x+3=4x−2=x=5/3
The equation y = –2 x + 3 represents the graphed function.
Answer: Option A
<u>Step-by-step explanation:</u>
As per the mapping points in the attached figure, A (0, 3) and B (1, 1)
Step 1: Find the slope of the line.
We know that the formula to calculate the slope between two points is equal to

. So, the slope ‘m’ would be

Step 2: Find the y-intercept
We know that the y-intercept is the value of y when the value of x is equal to zero. In this problem the y-intercept is the point A (0, 3)
Step 3: Find the equation of the line into slope-intercept form
We know that the equation of the line into slope-intercept form is equal to
y = m x + b
We have m = - 2 and b = 3 as b is equal to the y-coordinate of the y-intercept. Substitute these, we get
y = - 2 x + 3
Answer:
x = -13/4
Step-by-step explanation:
5 - (4x + 7) - 4 = 7
Distribute the minus sign
5 - 4x -7 - 4 = 7
Combine like terms
-4x-6 = 7
Add 6 to each side
-4x-6+6 = 7+6
-4x= 13
Divide by -4
-4x/-4 = 13/-4
x = -13/4
Answer:
g(-8) = -62
Step-by-step explanation:
g(x) = 8x+2
What is x when g(x) = -62
-62 = 8x+2
Subtract 2 from each side
-62-2 = 8x+2-2
-64 = 8x
Divide by 8
-64/8 = 8x/8
-8 = x
