Original balance 400
paid 20
new balance = 380 charged additional 18
new balance 398 interest of 2% on this entire amount
.o2 x 398 = $ 7.96 interest
We did a Q for you yesterday that is almost exactly like this one , MS....you should be able to complete this one......COLLINEAR means "on the same line" Which sets are on the same line(s) ?
If the sale is 95% OFF then you pay only 5%
5% x 57 =
.05 x 57 = 2.85 = sale price
If the sale is pay only 95% of original price (the Q does not say which way the sale works)
then you pay .95 x 57
Use a ratio system
5.1 ft is to 19 inches as tree h is to 66.5
5.1/19 = h / 66.5
5.1/19 * 66.5 = h
h= 17.85 ft tall
Rate * t = Distance
t is the time @ 17 mph
4hrs-t is the time at 22 mph
17*t + 22(4-t) = 70
17t + 88 - 22t = 70
-5t = -18
t = 3.6 hrs @ 17 mph .4 hr @ 22
12 ft x 18 ft is 4 yd x 6 yd = 24 yd2
24 (18.96 + 6.50 ) = total cost
2y-x=-8 put x and y on opposite sides
2y = x-8 divide both sides by 2
y = 1/2 x -4 add 4 to both sides
(y+4) = 1/2 (x-0)
or re-arranging a bit
(y+2) = 1/2 (x-4) would be another form
Here is an equation of a LINE that passes through them
find the slope
(y2-y1)/(x2-x1) note that it does not matter which point you choose as x1,y1 or x2,y2
(-4- -2) / (-1 - 3) = -2/-4 = 1/2 = m
point slope form would be:
(y+4) = 1/2 (x+1)
More than TEN of them ...Thanx guest...... I may have to look at this for a while longer !
3*y-(4*(2-y)=3(y-4) expand L and R sides
3y - 8+4y = 3y-12 subtract 3y from both sides
- 8 + 4y = -12 add 8 to both sides
4y = -4 divide by 4
y = -1
