Answer:
Step-by-step explanation:
Let the number of dimes be d and quarters be q
<u>The value is $8.80 = 880¢, so:</u>
- 10d + 25q = 880 ⇒ 2d + 5q = 176
<u>If the dimes were quarters and the quarters were dimes, the coins' total value would be $7.30 or 730¢</u>
- 25d + 10q = 730 ⇒ 5d + 2q = 146
<u>Now we have 2 equations. Solving the system by elimination, subtract 5 times the second equation from twice the first equation:</u>
- 2(2d + 5q) - 5(5d + 2q) = 2(176) - 5(146)
- 4d - 25d = -378
- -21d = -378
- d = -378/-21
- d = 18
Answer:
It's a horizontal line passing through 4 on the y-axis.
Simply place a ruler at 4 and draw a straight line from left to right, which passing through the number 4.
The y-intercept is the y value when x = 0, or (0 , y)
Based on the graph, your y-intercept is at (0 , 2) or 2
The slope(m) can be found using the slope formula and plugging in 2 points:
But if you look at the answer choices, if the slope is positive, the line would be going up and to the right
If the slope is negative, the line would be going down and to the right
your answer is A
