Answer:
1. y=4
2.x=1
3. Y intercept (0.5)
4.x intercept (-2.5,0)
5.slope is 2
6. y=2x+5
Step-by-step explanation:
1&2use the graph to see that when x is -1 it touches y at 4.
3.Y intercept is where the line touches the Y Axis in this case at (0.5)
4.x intercept is where the line touches at the X axis
5.slope you can do rise over run, it goes up 4
from one point to another and 2 across, 4/2=2.
6. y=mx+b
mx is slope, so its 2 and b is the y intercept is 5 so its 2x+5.
If you're simplifying the equation your answer is going to become -d^3 +3d^2 +23d -30
Let x and y be the number of dimes and quarters that Isaiah has. The sum of these variables should be 24 and the total value be $3.45. The equations that would best represent the situation are,
x + y = 24
0.1x + 0.25y = 3.45
The values of x and y are 17 and 7, respectively. Thus, the answer is the second choice.
Let s represent the cost of a pair of socks.
.. 15.95 +5s -4.20 = 10s
.. 11.75 = 5s
.. 2.35 = s
Any of the above equations will get you to the cost of a pair of socks, which is
$2.35.
