Answer:
(a) f(7) = 23
(b) x = 13/3
Step-by-step explanation:
Step 1: Define
f(x) = 3x + 2
(a) f(7) is x = 7
(b) f(x) = 15
Step 2: Substitute and Evaluate
(a) f(7) = 3(7) + 2
f(7) = 21 + 2
f(7) = 23
(b) 15 = 3x + 2
13 = 3x
x = 13/3
Answer:
A. 
Step-by-step explanation:
The equation in slope-intercept form, 
, can be created to be used in finding Jack's pay. We need to find the slope (m) and the y-intercept (b) of the linear function.
Using two points (1, 18), and (1.5, 23), find the slope (m):
Slope (m) = 
Find b, by substituting x = 1, f(x) = 18, and m = 10 into .
Subtract 10 from each side
Substitute m = 10 and b = 8 into .
✅Thus, the linear function that can be used to find Jack's pay would be:
Answer: If I am correct, I do believe that A is equal to F, meaning that the angle of A, which is 100°, is also the angle of F.
Step-by-step explanation:
Sorry if I am wrong I'm new at this.
Answer:
(-3, 3)
Step-by-step explanation:
Substitute for y:
x+6 = -2x -3
3x = -9 . . . . . . . add 2x -6 to both sides
x = -3 . . . . . . . . divide by 3
y = (-3) +6 = 3 . . substitute for x in the first equation
The solution is ...
(x, y) = (-3, 3)
Answer:
b. When you divide both sides by 2x = 6x it could lead us to think that there is no solution while, in fact, the solution is x = 0.
Step-by-step explanation:
The solution is correct up to the step 2x = 6x
2x = 6x
Subtract 2x from both sides.
0 = 4x
Divide both sides by 4.
x = 0
You cannot divide both sides by x since x could be zero, and in fact, it is.
Answer: b. When you divide both sides by 2x = 6x it could lead us to think that there is no solution while, in fact, the solution is x = 0.
