Answer:
All you have to do is insert the first value where the x is, and the second value where the y is.
y = 3x + 5
11 = 3(2) + 5
11 = 6 + 5
11 = 11
So, this is right.
Now, let's check (3,13)
y = 3x + 5
13 = 3(3) + 5
13 = 9 + 5
13 = 14
This is NOT true. So, your answer is: Only (2,11)
Hope this helps!
Answer:
The standard form for linear equations in two variables is Ax+By=C. For example, 2x+3y=5 is a linear equation in standard form. When an equation is given in this form, it's pretty easy to find both intercepts (x and y). This form is also very useful when solving systems of two linear equations.
Step-by-step explanation:
From points (2, 0) and (6, 0), you can get base = 6 - 2 = 4.
From point (8, 5), you get a height of length 5.
A = bh/2 = 4 * 5/2 = 10
Area = 10 square units
Step-by-step explanation:
if x is games won
then games lost is x+14
total no of games=40
x+x+14=40
2x=40-14
x=13 games won
You can see if the other angles add up to 180 or 360 degrees (depending on shape) then add them to make it the number, for example, if a triangle has a right angle, then the other 2 angles are 45 degrees, knowing that EVERY triangle's angles add up to 180 degrees.
