Answer:
6x^2-5x+1
Step-by-step explanation:
Use the foil method:
multiply 2x with 3x and -1.
then multiply -1 with 3x and -1
when multiplied, you should have gotten 2x×3x=6x^2, then 2x×-1, then -1×3x=-3x, then you put all of the answers in order from variables with exponents to normal variables to non variables
Answer:
4 hours 7 minutes
Step-by-step explanation:
Since Trevon takes 10 hours to clean the attic, he cleans 1/10, 10% or .1 of the attic per hour. Since Cody takes 7 hours to clean the attic, he cleans 1/7, 14.3% or .143 of the attic per hour.
Together, that means they clean .1 + .143 of the attic per hour. That's an hourly rate of:
.1 + .143 = .243
The portion of the attic they clean in x hours is .243x. We'd like to know how long it will take them to clean 100% or 1 of the attic. So:
.243x = 1 Divide each side by .243
x = 1/.243
x ≈ 4.115
Let's convert .115 to minutes by multiplying by 60
.115 * 60 = 6.9 round to 7 for 7 minutes
It will take them around 4 hours 7 minutes to clean the attic.
Hi there!
The general form of the equation of a line in slope-intercept form is
y = ax + b
With 'a' representing the slope of the line. We know that the slope of this line is 1/4, so we can plug in this value into the equation of the line.
y = 1/4 x + b
When the line passes through the point (0,0) we can also plug in the x- and y-coordinate into the equation, and we'll see that some easy algebra will help us find our solution.
0 = (1/4) * 0 + b
First switch sides
(1/4) * 0 + b = 0
Multiply
0 + b = 0
b = 0
Now we've found our value of 'b', which we can plug back into the equation in slope-intercept form to find our final solution.
y = 1/4 x
or
f(x) = 1/4 x

The property of zero it is in simplest form
Answer:
53.7
Step-by-step explanation:
So first move the decimal in 2.3 by one to the left, making it 23. Now what you do to one thing you do to the other, now 123.51 becomes 1235.1. Now you have 1235.1 / 23. 23 goes into 1235; 53 times, leaving you with 16.1. Now we take 16.1 / 23. When you do that you get .7. Therefore your answer is 53.7
Hopefully this helped!
