Answer: 75.6% (C)
Step-by-step explanation:
since you are removing ten percent you just find 90 percent of ur original grade so 90 percent of 84.
The solutions for the inequality are -
<h3>What is the general equation of a Straight line? What is linear inequality?</h3>
The general equation of a straight line is -
[y] = [m]x + [c]
where -
[m] → is slope of line which tells the unit rate of change of [y] with respect to [x].
[c] → is the y - intercept i.e. the point where the graph cuts the [y] axis.
A inequality is used to compare two or more expressions. The straight line inequalities are of the form -
y > mx + c
y < mx + c
y ≥ mx + c
y ≤ mx + c
We have the following inequality -
x + 3y > 6
We can write -
x + 3y > 6
3y > - x + 6
y > (-1/3)x + 2
Refer to the graph of the inequality attached. The plotted points in the shaded region represent the solutions for the inequality. We can write -
Therefore, the solutions for the inequality are -

Answer:
Step-by-step explanation:
㏒ 3+㏒(x+2)=1
㏒3(x+2)=1
3(x+2)=10^1
3x+6=10
3x=10-6=4
x=4/3
so A
3.
Answer:
true
Step-by-step explanation:
....................
We solve the question as follows:
Simple interest=Principle×Rate×Time
Thus given:
p=$55000, R=2.5%, time= 1 year
thus
Interest=55000×0.025×1=$1375
To evaluate the amount required to keep up with the inflation, your interest rate should match the inflation rate otherwise prices are going up faster than the savings.
Required interest rate=55000×0.034×1=$1870
The buying power lost will be the difference between your required interest and actual interest.
Thus:
Buying power lost=1870-1375=$495
