Step-by-step explanation:

Step 1 - Separate LHS and RHS of the given polynomial.

--- (1)

y = x + 1 --- (2)

Step 2 - Draw the graph of a line (y = x + 1) that passes through the points (-1,0) and (0,1).

Step 3 - Now, draw the graph of the equation (1). The shape of this graph is the upward parabola.

Step 4 - The two graphs intersect each other at (-1,0) and (2,3).

From the above steps, it can be concluded that the correct option is C).

Which of these systems of equations shows the solution for the graph?
I am Lyosha [343]

Answer:

C)

Step-by-step explanation:

Note that one of the lines is simply y=-1 for any x, so we can dismiss the only answer without y=-1. That rejected answer is A)

Now let's notice, that the other line is decreasing y when increasing x. That tells us that in the equation y = ax + b, a has to be negative. This brings us to reject option D).

What is the y of that line for x = 0? Because y = ax + b, for x = 0 we will get the value of b. This is called the intercept. The line is at y=4 for x=0, so we know that the b in the equation must be positive 4. This fits answer C, but rejects answer B). And so, we have found that C) is the only possible answer.

At the movie theatre, child admission is $5.90
Alik [6]
Let the number of children be c, and the number of adults be a.
c + a = 170 (total number of tickets)
Then the cost of each is: $5.90/child, $9.60/adult:
5.9c + 9.6a = 1269.40 (total sales)
Solving as 2 simultaneous equations, we first transform the first equation:
a = 170 - c
Substitute into the 2nd equation:
5.9c + 9.6(170 - c) = 1269.40
Solving gives c = 98, and a = 170 - 98 = 72. This means that 72 adult tickets were sold that day.
