Answer:
Alternatively you can write it as;
Step-by-step explanation:
One time service fee=$99
Rate of service=$50/hour
let unknown hours=x
Therefore the equation is
or you can further simplify it to:
And you can then solve for x to be 9 hours.
4. 7•5=35ft
Rectangle to find area is A=bh
Since it’s absolute value 70 = 70
Make up a word problem where the solution is 70. For example, Bob had 90 pencils but lost 20, how many does he have now?
Answer:
(2, 1)
Step-by-step explanation:
To solve by substitution, we solve one equation for one of its variables and then substitute the solved value for that variable into the other equation. Because this system of equations already has one solved for the variable, this makes our job much easier. We only need to implement the solved value for y into the other equation and solve for x.
y = 6x - 11
-2x - 3(6x - 11) = -7 Distribute.
-2x - 18x + 33 = -7 Combine like terms.
-20x + 33 = -7 Subtract 33 from both sides of the equation.
-20x = -40 Divide by -20 on both sides of the equation.
x = 2
Then, with this value, we will place it into the equation that was already solved for y in order to get a definite value for y.
y = 6(2) - 11
y = 12 - 11
y = 1
Using this information, the coordinate pair for this equation (the point of intersection between the two lines) is (2, 1).
It would be written as “The logarithm of [number] to the base e”.
(e stands for the constant, Euler’s number.)
