Answer: -2(5) over -1(6)
Step-by-step explanation:
1. X^2 - 3x - 10
X + 2 = 0 ⇒ −2
X1 = X − 5 = 0 ⇒ X2 = 5
2. X^2 - 5x - 6
X + 1 = 0 ⇒ X1 = −1
X − 6 = 0 ⇒ X2 = 6
Answer:
$3
Step-by-step explanation:
Martin get's $8 EVERY WEEK
So, in 5 weeks, he will get:
8 * 5 = $40
He saves up all the 5 weeks, so he has all the money.
After 5 weeks, he has:
$40
Now, he decides to buy a helmet for $37. So the amount remaining is:
40 - 37 = $3
So, Martin has $3 currently
The answer is y= -1x+8
Step-by-step explanation:
y=mx+b
m= -1
y-y=m(x-x1)
y-5=-1(x-3)
y-5=-1x+3
+5 +5
y=-1x+8
Answer:
Step-by-step explanation:
Use the compound amount formula: A = P(1 + r)^t, where r is the annual interest rate as a decimal fraction, P is the initial amount of money, and t is the time in years. Then:
A = ($240,000)(1 + 0.04)^12 (that's 12 years past 2008)
= ($240,000)(1.04)^12 = $384,247.73
Growth rate: 4%, or 0.04
Independent variable: time (t)
Dependent variable: appreciated value of the house, A
Domain: [0, 30) (assuming that the house is sold within 30 years)
Range: [$240,000, infinity) (the house will never sell for an infinite price)
