A. Is a function B. Is not. The way you tell us you draw straight lines through the graph if any of the lines intersect with the thing plotted more than once it’s not a function, if it only intersects once it’s a function.
Answer
Step-by-step explanation:
The answers are following
sol1 y = x-1
sol2 y= x+ 7
sol4 y = x+4
Step-by-step explanation:
Solution 1
Here we are going put the point in the given equation ( given in the options)
If the each point satisfies any equation, that will be the relationship between x and y.
Given points are (-3,-4) , (2,1) , (5,4)
Let us take the option C as y = x -1
-4 = -3-1
1 = 2-1
4=5-1
Putting each value in the given equation we get LHS and RHS are same for all points. so, C is the answer.
Similarly, option B is the answer of Solution 2
Each point satisfies the equation y = x +7
Solution 4
y = x +4
You are requested to check the options of Q3 once.
let x =the number
Step-by-step explanation:
81+x=3x-39
group like terms
81+39=3x-x
120=2x
120/2=2x/2
60=x
therefore x =60
Hello, hope this makes some sense, the midpoint formula is what’s given in the picture and the rest is just substitution
