Answer:

Step-by-step explanation:

Isolate y

Divide both sides of the equation by -3

Answer:
The x-intercept of the straight line is at (2,0) and the y-intercept is at (0,2).
Join those two points with a straight line and get the graph.
Step-by-step explanation:
The intercept form of a straight line equation is
, where the x-intercept of the line is at (a,0) and the y-intercept will be at (0,b).
So, we have to arrange the equation of a straight line in the intercept form and then we can easily find the x-intercept and y-intercept of the line.
Given equation is x + y = 2
⇒
Therefore, the x-intercept of the straight line is at (2,0) and the y-intercept is at (0,2).
Now, locate the two points as obtained on the graph and join them with a straight line and you will get the graph of the line. (Answer)
I am thinking your answer is 78 students. You do 1/5 times 390. And I think the the part about the dog is just extra information.
C = R - p
add C to both sides
R = C + p
subtract p from both sides
R - p = C ⇒ C = R - p
Take $438÷4=109.5 take 184-109.5=74.5. Then 74.5×4=298. The correct answer is C.
