Given:
Triangle Point coordinates or vertices:
A(16,0)
B(9,2)
C(2,0)
Required:
Side with slope -2/7
Solution:
To know which side has the slope required, we need to calculate the slope of each paired point by the two-point slope formula:
m = (y2-y1)/(x2-x1)
We first try points A and B.
m1 = (2-0)/(9-16)
m1 = -2/7
Thus, the side with the slope -2/7 is side AB.
Answer:
Step-by-step explanation:
33×10^-3 is equivalent to 33/1000, or 0.033.
This, in turn, is equivalent to 3.3×10^(-2) (which is in scientific notation)
Answer:
x = -2
y = - 5
Step-by-step explanation:
-5y - 10x = 45
-3y + 10x = -5
------------------------Add
-8y = 40
y = -5
-3(-5) + 10x = -5
15 + 10x = -5
10x = -20
x = -2
Answer
x = -2 and y = - 5
3 9

15 6
Compare diagonally to see if they the 2 numbers simplify.
Ex:
3 and 6 Simplify to 1 and 2 because they are both multiples of 3.
9 and 15 Simplify to 3 and 5 because they are both multiples of 3 as well.
Now our fractions are
1 3

5 2
Now multiply across to get your final fraction/answer
