Answer:
(- 8, 8 )
Step-by-step explanation:
Given ( ?, 8 ) is a solution. To find x substitute y = 8 into the equation, then
- 4x - 8 = 24 ( add 8 to both sides )
- 4x = 32 ( divide both sides by - 4 )
x = - 8
Thus solution is (- 8, 8 )
Answer: m = 1/2
Step-by-step explanation: To find the slope of the line, we would first put the equation in y = mx + b form to get y by itself on the left side.
So divide both sides by 2 to get y = 1/2x - 4.
Now the slope is the coefficient of the x term which is 1/2.
This is a positive slope.
Answer:
soln,
price of textbook = $40
tax% = 10%
now,
tax amount = 10% of $40
= 10\100*40
= 10*4/10
= 40/10
= $4.
again,
final price = cost of textbook+tax
=$40+$4
=$44.
Step-by-step explanation:
so the total price of a Textbook is $40 which is 100% and the tax is 10% so you need to find tax from the price of the textbook which is 10% of the price of the textbook then add the price of the textbook with the tax amount which is the final cost .
Answer:
$95.62
Step-by-step explanation:
15% of $112.50 = $16.875. round that to $16.88.
$112.50-$16.88=$95.62
Answer:-5
Step-by-step explanation:
You need to distribute on both sides so u get
9c-15=20-2c
Move variable to left side and change the sign
-9c+2c-15=20
Move constant to right side and change the sign
-9c+2c=20+15
Connect like terms
-7c=35
Divide
C=-5
