Answer:
Combine -15 + 2n first, then you get -13 n.
Then work from -13n to subtracting -9n, that is -4n. Now all you have left is -4n = 8. Divide both sides by -4n/-4 8/-4. The answer is n = -2.
Step-by-step explanation:
Answer:
Step-by-step explanation:
4x-3+7x+1
4x, 7x are like terms because the both have an x
-3,1 are like terms because they are both constants
4x+7x-3+1
11x -2
The Absolute value bars act as the P in PEMDAZ (The P = Parenthesis but it really just means any containing symbols ( (), {}, [], || ) so you distrubute -2 into the bars resulting in the numbers becoming negative then you follow the steps down :)
Answer:
Store 2
Step-by-step explanation:
Drawing graphs will help you understand better
S1
y = 25x + 100
S2
y = 30x + 50
Where y is the total cost that needs to be paid
And x is the number of packages
Store 1
y = 25(5) + 100
y = 125 + 100
y = 225
Store 2
y = 30(5) + 50
y = 150 + 50
y = 200
Given the point U and point V, the midpoint between of the line segment UV is ( 0, -5/2 ).
<h3>What is the midpoint of line UV?</h3>
The midpoint formula is used to find the midpoint of a line segment.
It is expressed as;
[ (x₁ + x₂ )/2 , (y₁ + y₂ )/2 ]
Given the data in the graph,
Point U = ( 3, -1 ) and Point V = ( -3, -4 )
- x₁ = 3
- x₂ = -3
- y₁ = -1
- y₂ = -4
We substitute into the formular above.
[ (x₁ + x₂ )/2 , (y₁ + y₂ )/2 ]
[ (3 + (-3) )/2 , ( (-1) + (-4) )/2 ]
[ 0/2, (-1-4)/2 ]
[ 0/2, -5 /2 ]
( 0, -5/2 )
Given the point U and point V, the midpoint between of the line segment UV is ( 0, -5/2 ).
