Answer:
x=2
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
2x−1−1=x−3−(−5+x)
2x−1−1=x−3+−1(−5+x)(Distribute the Negative Sign)
2x−1−1=x+−3+(−1)(−5)+−1x
2x−1−1=x+−3+5+−x
2x+−1+−1=x+−3+5+−x
(2x)+(−1+−1)=(x+−x)+(−3+5)(Combine Like Terms)
2x+−2=2
2x−2=2
Step 2: Add 2 to both sides.
2x−2+2=2+2
2x=4
Step 3: Divide both sides by 2.
2x
2
=

x=2
Answer:
No
Step-by-step explanation:
-8 is less than -4. Negative numbers reverse the logic of positive ones: since positive 8 is more than positive 4, negative 8 is less than negative 4.
Answer:
i - 6d/0.5
that's all i remember ive done this before but my memory is wack, im sorry
If the coefficient squared is greater than one (multiplication), it stretches the graph vertically by the factor of the coefficient.
If the coefficient squared is less than one (division), it compresses the graph vertically by the factor of the coefficient.
Answer:
The correct answer is that a rose bush costs $10 and a shrub costs $4
Step-by-step explanation:
To solve this, start by writing equations for what each spent. Use x for the cost of a rose bush and y for the cost of a shrub. Below would be the equations for each.
Rob: 8x + 5y = 100
Amy: 8x + 8y = 112
Now to find the cost, we multiply Rob's equation by -1 and add them together. This will get x to cancel and allow us to solve for y.
-8x - 5y = -100
8x + 8y = 112
------------------
3y = 12
y = 4
So we know the cost of a shrub is $4. Now we can plug that in to either of the original equations and solve for the rose bush cost.
8x + 5y = 100
8x + 5(4) = 100
8x + 20 = 100
8x = 80
x = 10
Which means that a rose bush costs $10.
