Answer: 0
Step-by-step explanation: In order to identify the <em>y-intercept</em> of this equation, we want to get this equation into slope-intercept form which is more commonly known as y = mx + b form.
The problem is our equation doesn't match up quite so well with the formula y = mx + b. Our slope or <em>m</em> which is represented by the coefficient of the <em>x</em> <em>term</em> is clearly +4 but what is our y-intercept or b?
Well y = 4x can be thought of as y = 4x + 0 so you can see that our b or y-intercept equals 0.
<u>Given </u><u>:</u><u>-</u>
- Milo bought 12 nails for $6 .
<u>To </u><u>Find</u><u> </u><u>:</u><u>-</u>
- To find the cost for 2 , 4 and 8 nails.
<u>Answer:</u><u>-</u>
According to the question ,
- Cost of 12 nails = $6
- Cost of 1 nail = $6/12
- Cost of 1 nail = $0.5
<u>Cost</u><u> </u><u>for </u><u>2</u><u> </u><u>nails </u><u>:</u><u>-</u>
- Cost of 2 nails = $0.5 *2 = $1
<u>Cost for 4 nails :-</u>
- Cost of 4 nails = $0.5 *4 = $2
<u>Cost for </u><u>8</u><u> </u><u>nails :-</u>
- Cost of 8 nails = $0.5 *8 = $4
Answer:
$3800
Step-by-step explanation:
When simple interest is added to the principal amount, the sum increases linearly with time. Essentially, you are asked for the y-intercept of a line that goes through the points (2, 6200) and (3, 7400). You can use the 2-point form of the equation of a line to find it:
y = (y2 -y1)/(x2 -x1)(x -x1) +y1
y = (7400 -6200)/(3 -2)(x -2) +6200 . . . . fill in given points
y = 1200(x -2) +6200 . . . . . . . . . simplify some
y = 1200x -2400 +6200 . . . . . . simplify more
y = 1200x +3800 . . . . . . . . . . . . . completely simplify
When the number of years (x) is zero, the amount is 3800. The principal is $3800.
_____
The account is earning $1200 per year on a principal of $3800. The interest rate is about 31.6%, an unusually high value.
_____
<em>Alternate solution</em>
You can recognize that the interest earned in one year is 7400 -6200 = 1200. Since this is simple interest, the amount of interest earned each year is the same, so in 3 years, the account has earned 3×$1200 = $3600 in interest. Then the original principal amount must be ...
$7400 -3600 = $3800 . . . . . principal amount
