Answer:
7 1/2
Step-by-step explanation:
If it drops 2 per hour, and you need it to drop 15, divide 15 by 2 and you’ll get 7.5 or 7 1/2
So you start by dividing 6 out of the expression and you get 6(4-3)
Subtract 7 from both sides
x^2 - 6x - 7 = 7 - 7
Simplify
x^2 - 6x - 7 = 0
Answer :
The final solutions to the quadratic equation are:
x = 7, -1
If you would like to simplify 21/78, you can do this using the following step:
21/78 = 7/26
<span><span>The result is </span>7/26 <span>(this is not a mixed number, because mixed
numbers can be made from numbers greater than 1 and 7/26 is less than 1).</span></span>
Step-by-step explanation:
y = -( 2+2)
- to find the intercept/ zero substitute y=0
- 0 = -(x-2+2) solve the equation for x
- x = 0
