Answer:
-4/-21
Step-by-step explanation:
First let establish the eqautionlet y be the total costx is the number of orders
y = 3x + 115
since the minimum order is 25x >= 25
then The school can spend a maximum of $800
800 <= 3x + 115
800 - 115 <= 3x685 <= 3x685/3 <= x228.33 <= x
Answer:
(a) x = -1.10 and x = 1.10
Step-by-step explanation:
A straightforward square root will give the value of x.
<h3>Solution</h3>
Divide by the coefficient of x^2:
x^2 -30/25 = 0
x^2 -1.20 = 0
Add 1.20, and take the square root.
x^2 = 1.20
x = ±√1.20 ≈ ±1.0954
x ≈ -1.10 and 1.10 . . . . . round to hundredths
__
<em>Additional comment</em>
For small values of x, the root of (1+x) is approximately 1+x/2. For a root accuracy to the nearest hundredth, x < 0.21 (as here). For accuracy to the nearest thousandth, x < 0.064.
Answer:
6 - 
3² - 
7 - 
= 
Step-by-step explanation:
1. 6 - 
First, apply the exponent to 2/3. Because it's to the second power, multiply 2/3 by itself.
6 - 
Now, subtract.
6 - =
------------------------------------------
2. 3² - 
First, apply the exponent.
3² = 9
9 -
Now, subtract.
9 - 
------------------------------------------
3. 7 -
First, apply the exponent.
= 
7 -
Now, subtract.
7 -
