<u>Question 1</u>
Step 1: Write out discriminant
d = b² - 4ac
Step 2: Subtract b² on both sides
d - b² = -4ac
Step 3: Divide both sides by -1
b² - d = 4ac
Step 4: Divide both sides by 4c
a = 
<u>Question 2</u>
Step 1: Write out equation
2/3(x - 18y) = 6y
Step 2: Distribute parenthesis
2/3x - 12y = 6y
Step 3: Isolate <em>x </em>by adding 12y on both sides
2/3x = 18y
Step 4: Divide both sides by 2/3
x = 27y
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!!
Answer:
for the first one its right 2 down 5
for the second one its right 5 down 2
for the third one its left 2 up 5
i hope this helps pls tell me if im wrong
If the value was initially v, then after a year it is 0.75v, after 2 years it’s 0.75²v, and so on. So after 6 years it’s 0.75⁶v.
So 0.75⁶v=7500, and v=7500/0.75⁶=$42,139.92 approximately. This is close to $42,140.
