because I had done the question with multiple words
Answer:
Step-by-step explanation:
let x represent the number of minutes of call made.
Let y represent the cost for x minutes of call.
If we plot y on the vertical axis and x on the horizontal axis, a straight line would be formed. The slope of the straight line would be
Slope, m = (10.86 - 5.91)/(10 - 5)
m = 4.95/5 = 0.99
The equation of the straight line can be represented in the slope-intercept form, y = mx + c
Where
c = intercept
m = slope
To determine the intercept, we would substitute x = 10, y = 10.86 and m = 0.99 into y = mx + c. It becomes
10.86 = 0.99 × 10 + c = 9.9 + c
c = 10.86 - 9.9
c = 0.96
The linear function becomes
y = 0.99x + 0.96
Therefore, for $12, the number of minutes would be
12 = 0.99x + 0.96
0.99x = 12 - 0.96
0.99x = 11.04
x = 11.04/0.99
x = 11.15 minutes
Answer:
A= 80
B= 37
C= 13
D= ? not sure apologies, did this a long time ago.
Step-by-step explanation:
Step-by-step explanation:
4.5-3=1.5 so that’s the pattern.
A.
so a equation could be L as last number of miles and 1.5 cause it goes up by that ever week. N as New number of miles. So C+1.5=N
B. So we gonna need a table
Week number | Last Week | New Number Of Miles
1 | N/A. | 3
2 | 3 | 4.5
3 Use chart given
4
5 | 7.5. | 9
6 | 9 | 10.5
7 |10.5 | 12
8 | 12 | 13.5
9 | 13.5 | 15
10 | 15 | 16.5
11 | 16.5 |18
12 | 18 | 19.5
13 | 19.5 | 21
14 | 21 | 22.5
22.5 IS NOT EQUAL TO 26.2, so no
For the answer to the question above, this can be solve using the distance formula: D = sqrt [ (x2 – x1)^2 + (y2 – y1)^2] So the expression she should use is: D = sqrt [ (7 – 1)^2 + (10 – 2)^2] Then the answer would be: D = sqrt [ (6)^2 + (8)^2] <span>D = 10 I hope my answer helped you.</span>
