We are given: Degrees Celsius and degrees Fahrenheit are related by formula
To find : Solve formula for F in terms of C.
Solution: We have ,
First we need to get rid 9 from right denominator.
In order to get rid 9 from right denominator, we need to multiply equation both sides by 9.
9C = 5 (F-32).
Distributing 5 on right side over (F-32), we get 5*F - 5*32 = 5F - 160.
9C = 5F - 160.
Adding 160 on both sides,
9C+160 = 5F - 160+160.
9C+160 =5F
Dividing both sides by 5, we get
(9C+160)/5 =5F/5.
Splitting fraction 1/5, we get
.
Add one to the other side and y=1/2
Unsecured credit cards could possibly be the answer
Answer:
9 × c or 9c
Step-by-step explanation:
Product means multiplication so the answer would be 9 × c. Since there is a variable, the answer doesn't even need the multiplication sign, but it is fine either way.
Answer:
a = 4, b = 
Step-by-step explanation:
Use any ordered pairs of points from the table.
Substitute into the equation and solve for a and b, that is
Using (0, 4), then
4 = a
= a
Hence a = 4
Using (2, 1), then
1 = 4
( divide both sides by 4 )
b² = 
( take the square root of both sides )
b =
Equation is
y = 4
