Answer:
From the graph,
- The line y = 7x + 3 is represented by a red line with y-intercept (0, 3)
- The line y = 2x + 6 is represented by a blue line with y-intercept (0, 6)
it is clear that the slope and y-intercept have been changed.
Step-by-step explanation:
The slope-intercept form of the line equation
y = mx+b
where m is the slope and b is the y-intercept
Given the equation of a line
y = 7x + 3
comparing with a slope-intercept form of the line equation
y = mx+b
Here,
The slope = m = 7
y-intercept = b = 3
Now, the equation changed to y = 2x + 6
y = 2x + 6
comparing with a slope-intercept form of the line equation
y = mx+b
Here,
The slope = m = 2
y-intercept = b = 6
Thus, if the equation was changed to y = 2x + 6, the slope and y-intercept also get changed from m = 7 to m = 2 and b = 3 to b = 6 respectively.
The lines of both equations is also attached.
From the graph,
- The line y = 7x + 3 is represented by a red line with y-intercept (0, 3)
- The line y = 2x + 6 is represented by a blue line with y-intercept (0, 6)
it is clear that the slope and y-intercept have been changed.
For this case we must solve the following linear equation:
Adding to both sides of the equation we have:
Subtracting 17 from both sides of the equation:
Different signs are subtracted and the major sign is placed:
We divide by 14 on both sides of the equation:
Answer:
Answer:
Infinitely many solutions
Step-by-step explanation:
2y=14-2x
y=-x+7
------------
2(-x+7)=14-2x
-2x+14=14-2x
-2x-(-2x)=14-14
-2x+2x=0
0=0
infinitely many solutions
(This answer is worth 8 points?? Don’t lie about that but I’ll still help.)
You have to find the unit rate of both of them. So divide 8.75/3.5=2.5 so Adam paid 2.5$ per oz
Then let’s find Marcos.
9.75/3.75=2.6 so Marco paid $2.5 per oz.
Adam got the better deal.
