It’s the parts on the graph so it would be Q1 Q2 Q3
Answer:
7
Step-by-step explanation:
You get the value of c and d as follow
c=4
d=28
now,
d/c=28/4=7
so,
the value of d/c here is 7
Answer:
The expression which represents the total number of miles he jogs in a week is 7 m ⇒ A
Step-by-step explanation:
Let us solve the question
∵ Dominic goes jogging every morning
∵ m represents the number of miles he jogs each day
→ That means he jogs m miles every day
∵ There are 7 days in a week
→ That means he jogs m miles every day for 7 days
∵ m + m + m + m + m + m + m = 7 × m
∴ He jogs in 1 week 7 × m miles
∴ He jogs 7 m miles in a week
The expression which represents the total number of miles he jogs in a week is 7 m
Answer:
y = -9 / 7x + 109 / 7
Step-by-step explanation:
To find the equation of any line, you must find the slope and y-intercept (when writing in slope-intercept form). In this case, we can find both of these values by using the two coordinate pairs that are given:
Slope - the change in y over the change in x
- 9 / -7 = -9 / 7
- slope = -9 / 7
- y-intercept - when x = 0
Right now, since we have the slope, we know the equation will look like this: y = -9 / 7x + b, b is what we are trying to find, the y-intercept. To find b, we can substitute a given coordinate pair that we know will fit this line and then solve:
- 13 = -9 / 7 x 2 + b
- 13 = -18 / 7 + b
- 91 / 7 + 18 / 7 = b
- 109 / 7 = b
After finding both the slope and y-intercept, we can now combine them together to form the equation of the line:
y = -9 / 7x + 109 / 7
Hope this helps!!
