For this case, what we are going to do is use the following property:
Multiply an equation by a scalar.
In this case, the scalar will be:
k = -2
We have then that equation 2 will be:
k * (4x + y) = k * 1
-2 * (4x + y) = - 2 * 1
-8x-2y = -2
Answer:
The property that justifies this manipulation is:
Multiply an equation by a scalar.
Answer: LCM = 720, GCF = 5 Please consider Brainliest.
Step-by-step explanation:
Find the least multiple of all three numbers, it should be 720. Find the Greatest factor, which should work. But remember, 15 doesn't work because 80 doesn't have 15 as a factor.
Answer:
140$
Step-by-step explanation:
You can use the three rule step.
20% ?
-------=------------
100%. 700$
Then u go 20 x 700 divided by 100 which gives you the 20% in $
Answer:
It's a horizontal line passing through 4 on the y-axis.
Simply place a ruler at 4 and draw a straight line from left to right, which passing through the number 4.
Answer:
Step-by-step explanation:
The angles add up to 90 degrees.
x + 2x + x + 10 = 90
Combine like terms.
4x + 10 = 90
Subtract 10 from both sides.
4x = 80
Divide both sides by 4.
x = 20
