Answer:
y = -1000x +11000
Step-by-step explanation:
<u>Given:</u>
(x, y) = (sales price, number sold) = (3, 8000), (6, 5000)
<u>Find</u>:
slope-intercept equation for a line through these points
<u>Solution</u>:
When given two points, it often works well to start with the 2-point form of the equation for a line.
y = (y2 -y1)/(x2 -x1)(x -x1) +y1
Filling in the given points, you have ...
y = (5000 -8000)/(6 -3)/(x -3) +8000
y = (-3000/3)(x -3) +8000
y = -1000x +3000 +8000 . . . . eliminate parentheses
y = -1000x +11000 . . . . the desired equation
90:18
divide using 3 on both sides
90:18
30:6
10:2
now lets use 2
10:2
5:1
5:1 is the equal ratio to 90:18

Answer:
12c=$14.04
Step-by-step explanation:
First lets find out how much each candy bar cost
14.04/12=1.17
so
$1.17*12 = $14.04
so d is the correct answer becuase you would need to multiply the cost of each candy which would be $1.17 by how many candy bars you have which is 12 then get the answer of the total cost that would be $14.04
Answer:
Move the decimal so there is one non-zero digit to the left of the decimal point. The number of decimal places you move will be the exponent on the
10
. If the decimal is being moved to the right, the exponent will be negative. If the decimal is being moved to the left, the exponent will be positive.
