Answer:
a = 0.5 or 1/2
b = 19/4 or 4.75
Step-by-step explanation:
Step 1: Isolate <em>x</em>'s
x² - x = -5
Step 2: Complete the Square
x² - x + 1/4 = -5 + 1/4
(x - 1/2)² = -19/4
Step 3: Move everything to one side
(x - 0.5)² + 4.75
Answer:
16.27
Step-by-step explanation:
if 1000m rep 1km
therefore :
58.6km/h in ms = 58.6km×1000/3600
=16.277 ms
Hey there!!
Given equation :
... c(x) = 29x + 54.5
<em>In this equation $54.50 is installation fee and this would remain as a constant. ( This value wouldn't change ). </em>
<em>'x' is represented as the number of months. </em>
The total cost or c(x) is given as $344.50
Getting this into equations :
... 344.50 = 29x + 54.5
Subtracting 54.5 on both sides :
... 29x = 290
Dividing by 29 on both sides :
... x = 10
<u><em>Hence, the number of months is 10. </em></u>
Hope my answer helps!!
X=-1
Trust me yurrrrrrrrrr
First, we’re going to use this formula:
2nd number - 1st number
————————————— x 100%
1st number
If we plug in the numbers to this equation:
23-20
———- x 100%
20
And subtract 23 to 20, the answer to this equation is:
3
—- x 100% = 15%
20
In this case, the percent of increase is 15%.
