Answer: y = -35x + 105
Step-by-step explanation:
The graph represents a function that is between hours and miles and to determine the equation which belong to this graph, we need to find the slope first by using two points from the graph which are (0, 105) and (3, 0).
The definition of slope is
m = (y2 - y1)/(x2 - x1)
= (0-105)/3-0
= -105/3
= -35
The slope is -35 and remember that the slope is the coefficient of the variable x. Therefore, the answer is:
y = -35x + 105
Answer:
Step-by-step explanation:
There are so many order pairs that can solve this equation.
To solve this problem, we choose any value of x and find y;
Given expression;
3x - y = 8
if x = 0,
3(0) - y = 8
-y = 8
y = -8;
(0,-8) is a solution
ii.
if x = 1,
3(1) - y = 8
- y = 8 - 3
y = -5
(1, -5) is a solution
Answer:

cups of grapes
Answer:
5x5
Step-by-step explanation:
What I did was that I worked out how x is 2 and then x equals 5
The answer would be -10. this is because -12+25 is equal to 13 then when the temperature decreases by 23 you have to subtract 23 from 13 giving you -10
