Given:
A straight line goes through (-2,1), (0,0), and (2,-1).
To find:
The slope of the given line.
Solution:
Slope formula
Consider any two points from the given points.
The line goes through (-2,1) and (0,0). So, the slope of the line is
Therefore, the slope of the line is 
.
To factor this polynomial you will have to first find the GCF of 81 and 48 and its 3.
So then you put 3 out the parentheses. 3(----).
Then you have to see how many times 3 goes into 81m and 48m. It is 27m and 16mn.
So then this is what you get, 3(27m-16mn)
Hope it helps you!!!
Answer:
C
Step-by-step explanation:
First, write 4 ½ in improper form. 2 × 4 + 1 = 9. So the fraction is 9/2.
Now divide:
9/2 ÷ 1/3
To divide by a fraction, multiply by the reciprocal:
9/2 × 3/1
27/2
13 1/2
Answer C.
Answer:
Step-by-step explanation:
Since x=-4 plug in the -4 into the equation to find y,
-5(-4)-4y=16
20-4y=16 -20 -20 __________
-4y=-4
-4y/-4=-4/-4
___________
y=1
So now you found both x and y so plug in both now to check if both are correct.
-5(-4)-4(1)=16
20-4=16
16=16
So both y and x are correct.
Hope this helps!:)
