-2n + 1.8 = 3.2
Subtract 1.8 from both sides
-2n = 1.4
Divide both sides by -2
n = 1.4/-2 = 0.7/-1 = -0.7
n = -0.7
Check your work:
-2(-0.7) + 1.8 = 3.2
1.4 + 1.8 = 3.2
3.2 = 3.2
The answer is B. -0.7
Answer:
I₂ = 757.12$ (after two years)
Step-by-step explanation:
When the realized interest is added to the basic investment at the end of each year, we use the following formula:
I₂ = I ( 1 + (r/100))² for two years
I₂ = 700 ( 1 + (4/100))² = 700 · 1.04² = 700 · 1.0816 = 757.12$
I₂ = 757.12$

Answer:
B and C
Step-by-step explanation:
In order to know your x and y intercept, first rearrange your equation in the form ax+by=c
<u>NB </u> c should always be one so if you rearrange and c is not one, divide the whole equation by the no. represented by c, then to know your x and y intercepts look at the reciprocal of the coefficients of x and y
For example
B. -4x+2y= -6
divide the whole equation by -6 to get
2/3x-1/3y=1
hence the x intercept will be the reciprocal of the coefficient of x which is 3/2
y intercept will be the reciprocal of the coefficient of y which is -3
so if you look at the line, the equation applies
The same will apply to C
The number of hours that Jasmine can work so she can afford the new headphones x = 6 weeks.
let x represent the number of weeks it will take to save enough money.
If she saves $11 each week, then in x weeks she will save 11x dollars.
Add this to the 107 she has already saved, and at the end of 11 weeks she will have
11x + 107 dollars.
We want the amount saved to be equal to the price of the bike, so our equation is
11x + 107 = 173
In a word problem, writing the equation is usually the hardest part. Now we solve the equation.
Subtract 107 from both sides to get
11x = 66
Divide both sides by 11 to get
x = 6 weeks.

Answer:
This situation of the recipe can be represented as y=x+5.5 and it is expected that x is ≥ 0 and y is ≥ 5.5.
What is the equation for this situation?
It is known the total amount of flour (y) is equivalent to the total amount of whole wheat flour (5.5) added to the total white flour (x). Therefore, the equation is:
y = x + 5.5
The possible values are
x = It is expected x is equalthan 0 or greater to it since the minimum amount of white flour that can be added is 0.
y = It is expected y is equal than 5.5 or greater to it since even if no
white flour is added the minimum total is 5.5.
