Y=mx+b
m is your rate of change
b is your y intercept
Answer:11:5
Step-by-step explanation: to find the ratio of gas to electricity
which is 55:25 ,you could leave ur answer at that but it is more preferable to find wats common which in here is 5 so the answer then becomes 11:5
Axis of symmetry = x = -b/2a
where y = ax² + bx + c
f(x) = x² + 6x - 1 ⇒ a = 1 ; b = 6 ; c = -1
x = -(6)/2(1) = -6/2 = -3
g(x) = -x² + 2 ⇒ a = -1 ; b = 0 ; c = 2
x = -0/2(-1) = 0/-2 = 0
h(x) = 2x² - 4x + 3 ⇒ a = 2 ; b = -4 ; c = 3
x = -(-4)/2(2) = 4/4 = 1
least : f(x) = x² + 6x - 1 ; axis of symmetry is -3
middle : g(x) = -x² + 2 ; axis of symmetry is 0
greatest : h(x) = 2x² - 4x + 3 ; axis of symmetry is 1
Answer:
About 7.84 years before the deer population is 400
Step-by-step explanation:
So first we write our equation
125(1.16)^x = 400
Then we divide all sides by 125
1.16^x=3.2
x log 1.16 = log 3.2
06445798922x=0.50514997832
x= 7.83688700862
7.83688700862 years to go!
7 per ticket, so 7x
R = revenue, total cost
B. R(x) = 7x
