Explanation:
f(x) = (x-4)(x+2)
1) For x-intercept, y will be 0
<u />
<u>x-intercept</u>: (4, 0), (-2, 0)
2) For vertex: x = -b/2a where ax² + bx + c
<u>Quadratic function</u>:
<u>vertex</u>:
y: (x-4)(x+2) = (1-4)(1+2) = -9
ordered pair of vertex: (1, -9)
3) For y-intercept, x will be 0
<u>y-intercept</u>: (0, -8)
Answer:
3(Y-2) +5Y =Y+22
3Y-6 +5Y=Y+22
3Y -6 +5Y-Y-22=0
3Y+5Y-Y-6-22=0
7Y-28=0
7Y=28
Y=28/7
Y=4
Step-by-step explanation:
16.5 oz are in a pound a half
Just add the two equations together.
2b = 18
b = 18/2
b = 9
9 = k + 10
9 - 10 = k
k = - 1
Answer:
23
Step-by-step explanation:
12+17+30+19+27+21+35=161
161÷7=23
