Yes you can! Say you have 5(2 + x) + 3x. The answer would be 10+8x because when you use the distributive property you will end up getting 5*2 5*x and once you multiply, it's obvious 5 times 2 is 10 and 5 times x will equal 5x. Then you add 5x and 3x and get 8x. So, the simplified expression here is 10+8x. When you have this as an answer it's proving your answer right. You can without using the distributive property. We can have 10+5x+3x and it will be your simplified expression. It's the same thing with equations too.
Answer:
Step-by-step explanation:
Given point (0, 1) and the slope m = 2
<u>Use point- slope form to find the equation of the line:</u>
- y - y₁ = m(x - x₁)
- y - 1 = 2(x - 0)
- y - 1 = 2x
- y = 2x + 1
The reflection will be on the other side of the y-axis.
Its coordinates will be (3, 7).
Answer:
1) 3000 + 125m
2) 3000 + 125m = 5000
3) M= 16
4) It would take 16 months
Step-by-step explanation:
Okay so no since there are no other transaction and you already have a balance of 3000 with a monthly Fee of 125 the equation shpuld be like this.
So every month you add 125,we dont know how much months we have to pay so we can use the variable given to us in this case “M”. So your base expression should look like this,
3000 + 125m (3000 base fee that doesnt change, and 125 every month fee)
Then it asked us to put it as the final balance as 5000, so using the base expression we can do this
3000 + 125m = 5000
Now to solve it you would solve it like any other equation
5000-3000=2000
2000=125m
2000/125= 16
Okay so m = 16
M in this case stands for months so the final answer would be it would take 16 months to reach the final balance of 5000
5x+4y = 73
-4x + 4y = -8
5x + 4y -(-4x+4y) = 73 -(-8)
5x + 4y + 4x - 4y = 81
5x + 4x + 4y - 4y = 81
9x = 81
x = 81÷9
x = 9
Substitute x = 9 into any of the equations to find y.
5(9) + 4y = 73
45 + 4y = 73
4y = 73 - 45
4y = 28
y = 28÷4
y=7
Answers :
x = 9
y = 7
