- Using
substitution
means you are going to solve one equation for one variable and substitute with
its value in the other equation in order to get also an equation with one
variable.
Answer:
The standard form of a quadratic equation is ax2+bx+c=0, where a,b and c are real numbers and a≠0.
Answer:
75 miles per hour
Step-by-step explanation:
ok divide 600 by 8
Use y=mx+b. This is for slope. If you're given a coordinate such as (3,2) think of "dibble and then shoot". Go right three and up two. Hope this helps :)
Answer:
Step-by-step explanation:
For compound interest, we use the formula A = P(1 + r/n)^{nt}, where A is the amount, P is the principle, r is the rate, n is the number of times compounded per period of time, and t is the time.
We can alter this for a decrease. Instead of adding r/n to 1, we can substract it:
A = 17,600 * (1 - 0.01175 / 1)^{1 * 11} = 15,454.24
After 11 years, the car will be worth $15,454.24
