If I could see the graph correctly, then the y-intercept should be -5.
Answer:
7c - 11
Step-by-step explanation:
To solve this, you are going to need to add like terms.
Since 5 and 2 both have a "c" next to them, you can add those together to equal 7c.
Then, since -13 and 2 do not have a "c", you can combine those together to equal -7.
Since there is no = , the closest you can get to solving this equation would then be 7c - 11.
Hope this helped!
Step-by-step explanation:
x = number of multiple choice questions
y = number of short response questions
x + y = 15
5x + 10y = 100
=>
x + 2y = 20
let's subtract the first from the second equation :
x + 2y = 20
- x + y = 15
--------------------
0 y = 5
x + y = 15
x + 5 = 15
x = 10
to graph you need to consider both equations as linear functions. and you need to transform them into e.g. a slope intercept form : y = ax + b
a is the slope, b is the y- intercept.
x + y = 15
transforms to
y = -x + 15
this line goes e.g. through the points (0, 15) and (1, 14).
and
x + 2y = 20
transforms to
2y = -x + 20
y = -x/2 + 10
this line goes e.g through (0, 10) and (2, 9).
the crossing point of both lines is the solution and should therefore be the point (10, 5) as calculated above.
