To find value of y in times o x we have to transfrom this equation.
LEts do this
x-0.25y=1.5 /-x subtract x both sides
-0.25y=1.5-x /*4 multiply by 4 both sides
-0.25y*4=4(1.5-x)
-1y=6-4x /*-1 multiply both sides by -1
y=4x-6
1. We assume, that the number 92 is 100% - because it's the output value of the task.
<span>2. We assume, that x is the value we are looking for. </span>
<span>3. If 100% equals 92, so we can write it down as 100%=92. </span>
<span>4. We know, that x% equals 46 of the output value, so we can write it down as x%=46. </span>
5. Now we have two simple equations:
1) 100%=92
2) x%=46
where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:
100%/x%=92/46
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.
7. Solution for 46 is what percent of 92
100%/x%=92/46
<span>(100/x)*x=(92/46)*x - </span>we multiply both sides of the equation by x
<span>100=2*x - </span>we divide both sides of the equation by (2) to get x
<span>100/2=x </span>
<span>50=x </span>
x=50
<span>now we have: </span>
<span>46 is 50% of 92
I hope this helps!

Answer:
1) A. y = x + 2
Once a line of best fit has been placed upon a scatter graph it is straightforward to find the equation. The general equation of a straight line is: y = mx + c Where m is the slope (gradient) of the line and c is the y-intercept.
4) d. strong positive correlation.
The slope of the line is positive. Most points lie close to the line.

Answer:
Interest Rate on 2-Year Loan...$435.6
Interest Rate on 5-Year Loan...$1,452
Step-by-step explanation:
The formula for calculating simple interest is as follows.
I = P x R x T,
where I = interest
P= Principal
R= interest rate
T= time
For the loan at 4.5 percent for 2 years, the interest will be
= $4,840 x 4.5/100 x 2
= $4,840 x 0.045 x 2
= $435.6
Total cost of the loan will principal plus interest
=$435.6 + $4,840
=$5,275.6
Monthly loan cost
= $5,275.6/24
=$219.81
Total loan cost..$5,275.6
Monthly loan cost ...$219.81
For the Loan at 6 percent for 5 years, the interest will be
= $4,840 x 6/100 x 5
= $4,840 x 0.06 x 5
=$1,452
Total cost of the loan will be principal plus interest
=$ 4,840 + $1,45
=$6,292
Monthly costs will be
=$6,292/60
=$104.87
Total loan cost... $6,292
Monthly loan costs... $104.87
