If y = 2, to find the value of y + 6, we need to substitute the value of y (2) into the expression y + 6. Substituting 2 for y, we get the equation 2 + 6. Since 2 + 6 = 8, that means that substituting y = 2 into the expression y + 6, we get 8.
Answer:
y=12
Step-by-step explanation:
y=2x ,so 2x=8x-x^2
x^2=8x-2x
x^2=6x
x^2/x=6x/x
x=6
y=2x ,2(6)
y=12
Answer:
3, 4, and 5
Step-by-step explanation:
To put it simply, 3 + 4 + 5 = 12 and the numbers are consecutive, next to each other.
The method:
The three consecutive numbers could be called x, x + 1, and x + 2 and we know that x + x + 1 + x + 2 = 12
This can be simplified to 3x + 3 = 12. Next, subtract 3 from both sides to get 3x = 9. Now, divide both sides by 3 to get x = 3.
This means that the first number is 3 and the other numbers are 4 (3 + 1) and 5 (3 + 2).
Hope this helps!
Answer:
2(5x + 2)
Step-by-step explanation:
Answer:
<em>It will be withheld $75 for federal income.</em>
Step-by-step explanation:
<u>Proportions</u>
Assuming the federal income tax is proportional to the earnings, we can establish the following relationship between the income tax (T) and the earnings (E):
T = k.E
Kimberly earned E=$500 and paid T=$50 for federal income tax, With this information, we can calculate the value of k:
50 = k ( 500)
k = 50 / 500
k = 0.1
The model is now:
T = 0.1*E
If Kimberl earns $750 next month, the tax will be:
T = 0.1*($750)
T = $75
It will be withheld $75 for federal income.
