Use the graph to determine the number of solutions the system has. x=4 y=x+3

Final answer is x=4, y=7.

Step-by-step explanation:

Questions says to use the graph to determine the number of solutions the system has. where system of equations are x=4 and y=x+3

any equation of the form x=k is a vertical line crossing x-axis at k.

So x=4 is a vertical line crossing x-axis at 4.

y=x+3 has slope m=1 and y-intercept b=3

So it passes through point (0,3) and for slope m=1, rise 1 up then 1 right to get new point.

Then final graph is given as shown in the picture.

We can see that both lines intersect at point (4,7).

Hence final answer is x=4, y=7.

step-by-step explanation:

the graph shows 30% of students walk. 80 students were questioned, so the number that said they walk is

30% × 80 = 0.30 × 80 = 24
