26 minus 3 is 23 , 23 minus 5 is 18, 18 minus 7 is 11 so i’m pretty sure
answer =11
Answer:
x - 4 = 0 and x - 2 = 0
Step-by-step explanation:

A: 45x + 30y = 1350
Since we don’t know how many adults and children are in the group, we use x and y
b: x-intercept= 30 y-intercept=45
To find the x-intercept you need to isolate the variable. 45x/45 = x
Then you do the same thing to the other side. 1350/45 = 30
So x=30
Same thing with the y-intercept.
30y/30 = y 1350/30 = 45
y=45 (Not really sure what it means by “what they represent” but I thinks it’s that there are 30 adult tickets and 45 children tickets )
c: so our points are (30,0) and (0,45) so you would graph that.
To find how many children tickets were bought if there were 20 adult tickets just look at the photo I put. I don’t know how to explain this.
Hope this helps
Answer:

Step-by-step explanation:
The equation of the line in slope-intercept form is:
y=mx+b
Where m the slope of the line and b the y-intercept.
When two points are given, it's convenient to calculate the slope first.
Suppose we know the line passes through points A(x1,y1) and B(x2,y2). The slope can be calculated with the equation:

The points are (3,5) and (-2,1):

The equation is now:

To calculate b, we use any of the given points and solve for b. Use (3,5):

Operate:

Solve:

The required equation of the line is:

When solved using the distributive property, it will equal 2b+6c
