Answer:
1) 16
2) 12
4) 4
5) 0
Step-by-step explanation:
Plug in the value for x in the equation above and solve for y for all 5.
Answer:
x = -2
Step-by-step explanation:
f(x) = 2( x^2 +9x -5x - 45)
f(x) = 2(x^2 + 4x - 45)
f(x) = 2x^2 +8x -90
axis of symmetry formula: x = -b / 2a
x = -(8) / 2(2)
x = -8 / 4
x = -2
*you can also graph the equation on a graphing calculator and find the middle of the parabola
Answer:
w=6, x=7, t=7, n=90, w=15/2
Step-by-step explanation:
a) 5w = 30
30/5 = 6
w=6
b) 3x-5=16
Add 5 to each side.
3x+5=16+5
3x=21
21/3=7
x=7
c) 10-t=17
10-t=17
17-10-7
-t=-7
Negative and a negative is a positive.
t=7
d) n/5 = 18
n=18 * 5
n=90
e.) 4w-12=2w+3
4w=2w+3+12
4w=2w+15
4w−2w=15
2w=15
w= 15/2
Answer:
y=+|x-3|
Step-by-step explanation:
We know it is positive because it is expanding upward. So +. We know it is x-3 because if it is inside the absolute value signs, the constant(-3 in this case) is opposite. So it is 3. And 3 matches with the vertex of the graph. And the ending is 0, so I omitted it bc its still on the x intercept, meaning it has a y value of 0.
The answer is D because -14.6 is the least and is the only one that has -14.6 first.
