Answer:
The answer is B
Step-by-step explanation:
plug 2 into x to see
A.
x^2 + 8
2^2 + 8
4 + 8 = 12
B.
3x^2 + 1
3(2)^2 + 1
3(4) + 1
12 + 1 = 13
C.
2x^3 + 5
2(2)^3 + 5
2(8) + 5
16 + 5 = 21
D.
x^2 + x
2^2 + 2
4 + 2 = 6
Answer:
z=2
Step-by-step explanation:
I used cross multiplication to solve this.
2/9z=1/9
1(9z)=2(9)
9z=18
z=2
Answer:
y=2x-6
Step-by-step explanation:
Parallel functions are functions with the same slopes but are in different positions on the coordinate plane (for this case it means that they have different y- intercepts)
So this means that the function will have a slope of 2
To find the equation we must plug in the value (1, -4) and find the new y-intercept(c)
(-4)= 2(1)+c
-4-2=c
-6=c
This means that the parallel function that goes through the point (1,-4) is
y=2x-6
X - 3 = 7 (only solution is 10)
2x + 5 = 11 (only solution is 3)
7x - 1 = 27 (only solution is 4)
4x + 2 = -6 (only solution is -2)
