It would be -2z+8. Because 3z+-5 is -2 and 2+6 is 8.
6%
You want to calculate the interest on $12000 at 6% interest per year after 5 year(s).
The formula we'll use for this is the simple interest formula, or:
Where:
P is the principal amount, $12000.00.
r is the interest rate, 6% per year, or in decimal form, 6/100=0.06.
t is the time involved, 5....year(s) time periods.
So, t is 5....year time periods.
To find the simple interest, we multiply 12000 × 0.06 × 5 to get that:
The interest is: $3600.00
Answer:
z = 1, z = 9
Step-by-step explanation:
Given
z² + 9 = 10z ( subtract 10z from both sides )
z² - 10z + 9 = 0
Consider the factors of the constant term (+ 9) which sum to give the coefficient of the z- term (- 10)
The factors are - 1 and - 9, since
- 1 × - 9 = 9 and - 1 - 9 = - 10, thus
(z - 1)(z - 9) = 0 ← in factored form
Equate each factor to zero and solve for z
z - 1 = 0 ⇒ z = 1
z - 9 = 0 ⇒ z = 9
The formula would be y₂-y₁ ÷ x₂-x₁
-1 :x₁
4 : y₁
4-4/5-(-1) = <u><em>0 </em></u>
5 : x₂
4 : y₂
0 is the slope
Answer:
y = 3
Step-by-step explanation:
(4, 3) and (7, 3), right? Look at the y-coordinate (3), which is the same for both points. This tells us that as x changes, y stays the same: y = 3. This is a horizontal line whose equation is merely y = 3.
