Answer:
C. $22
Step-by-step explanation:
We are given a graph showing the relation between the distance travelled in miles by taxi and the taxi fare.
To find an estimate of how much her taxi fare would be if she travelled 8.5 miles by taxi, simply look 8.5 on the x-axis, then trace it upwards till it meets the line. The point where it meets the line would be the corresponding y-value of x = 8.5.
The point would be (8.5, 22). This means, if the woman travels 8.5 miles, her taxi charges would be approximately $22.
Answer:
C
Step-by-step explanation:
Noting that
+ (- ) is equivalent to subtraction
- (- ) is equivalent to addition
Given
13 + (- 12) - (- 5)
= 13 - 12 + 5
= 1 + 5
= 6 → C
The answer is <span>2(–4y + 13) – 3y = –29
Step 1: Express </span><span>x from the second equation
Step 2: Substitute x into the first equation:
The system of equations is:
</span><span>2x – 3y = –29
x + 4y = 13
Step 1:
</span>The second equation is: x + 4y = 13
Rearrange it to get x: x = - 4y + 13
Step 2:
The first equation is: 2x – 3y = –29
The second equation is: x = - 4y + 13
Substitute x from the second equation into the first one:
2(-4y + 13) - 3y = -29
Therefore, the second choice is correct.
