Answer:
Step-by-step explanation:
The summary of the given parameters are:
--- initial savings
--- monthly savings
months
Required
The linear function
The linear function is calculated using:
y(t) = Initial Savings + Monthly Savings * Months
So, we have:
Let n = the number
(n-3)(8)=9
Multiply
8n-23=9
Add 23 to both sides
8n=32
Divide by 8 on both sides
n=4
I am doing the K12 program and i was taking the test when you asked this and it said the answer is 7/10. This is 100% correct.
Step-by-step explanation:
ax^2+bx+c=0
a=leading term
ok so if the leading term is positive then opens up and has a <u>min</u>
if leading term is negative then opens down and has a <u>max</u>
leading term is positive
1x^2+8x
it has a min
to complete the square, move c aside take 1/2 of b and square it
b=8
8/2=4
4^2=16
now add that to both sides
x^2+8x+16+6=0+16
factor perfect square
(x+4)^2+6=16
subtract 6
(x+4)^2=10
subtract 10
(x+4)^2-10=0
vertex aka min or max is (h,k) when ou have
y=a(x-h)+k
h=-4
k=-10
Answer:
About 12 minutes
Step-by-step explanation:
2/3 = 0.666666667
0.67/1 = 8 min/x min
Cross multiply:
8•1=8
8 divided by 0.6666667 = 11.9999994
