Answer:
y = −55x + 275
The initial value is 5
Mike's distance from home when he begins cycling
Step-by-step explanation:
The equation of a line is
y= mx+b where m is the slope and b is the y intercept
The y intercept is 275
Two points are (0,275) and (5,0)
The slope is (y2-y1)/(x2-x1) = (0-275)/(5-0) = -275/5 =-55
y = -55x+275
The initial value is when x = 0
When x = 0 , y = 5
y = 12-2x
Rewriting
y = -2x+12
This is in the form y = mx +b where the slope is -2 and the y intercept is 12
12 is the initial value or when x = 0. It would be the distance that he needs to cover. He needs to go from the library to his house.
Part 2 is 12.5 cm represents 5km
I worked this out by doing a ratio
5cm=2km
?cm=5km
you have to do 2 times 2.5 to get 5km so you do 5 times 2.5 to get 12.5cm
so the answer is that 12.5cm
Answer:
A
Step-by-step explanation:
-3 1/3 or -10/3, so A is the correct answer.
Answer:
the given amount percentage is $15, $9 and $12 respectively
Step-by-step explanation:
The percentage of the given amounts are shown below:
a. 60% of $25 = $15
b. 25% of $36 = $9
c. 10% of $120 = $12
Hence, the given amount percentage is $15, $9 and $12 respectively
Answer:
It 12 units!!!!
Step-by-step explanation:
