7over10 subtract 5over12 in simplest form
Andrews [41]

Answer: =\frac{17}{60}\quad \left(\mathrm{Decimal:\quad }\:0.28333\dots \right)

Step-by-step explanation:

\left(\frac{7}{10}\right)-\left(\frac{5}{12}\right)

=\frac{7}{10}-\frac{5}{12}

=\frac{42}{60}-\frac{25}{60}

=\frac{42-25}{60}

Which two points satisfy y=-x2(^)+2x+4 and x+y=4?
Wewaii [24]
Use subtitution method to solve the problem.

First, change y to the value of x in order to find the exact value of x.
x + y = 4
y = 4 - x

Second, subtitute y with 4 - x from the first equation
y = -x² + 2x + 4
4 - x = -x² + 2x + 4
move all terms to the left side
x² - 2x - x + 4 - 4 = 0
x² - 3x = 0
x(x - 3) = 0
x = 0 or x = 3

Third, now we have 2 values of x. Find the value of y for each of x
For x = 0
y = 4 - x
y = 4 - 0
y = 4

For x = 3
y = 4 - x
y = 4 - 3
y = 1

The solution is (0,4) and (3,1). The answer is option b

Can you think of three examples of real world parallel and/or perpendicular lines? Explain why they are important in the real-wo
Naddika [18.5K]

Answer: The road, crucifix/cross, sidewalks, railroads, and so much more.

Step-by-step explanation: Roads are parallel so that everyone can get to the same place in different lanes. This is important because lines that aren't parallel will inevitably meet, meaning that a highway would eventually merge its two lanes. This happens, but most of the highway is parallel. The same is true of sidewalks and railroads. The crucifix/cross is a Christian symbol, and while I'm not Christian, I'm sure it's important to a lot of people who are.
