Answer:
y=3/2x+0
Step-by-step explanation:
The formula for slope intercept form formula is y=mx+b where m is the slope and b is the y intercept and since the slope is rise over run ( or rise/run just put it into fraction form) we count from the y intercept up until we can see the line reach a point where it touches a actual cross point ( in this case from the y intercept we see it goes up three) Then we count over how many to that cross point ( the full point, not just a random place on the chart) (in this case 2) and that creates 3/2. Now for the y intercept. Where does the line intercept the vertical line? That's your y intercept. In this case it's 0. Now you can see where we count up from three ( for the slope) and over two. Right onto that point. Hope this makes sense! If not look up Khan academy for some extra tutoring that is free.
Hope this helps! If so please mark brainliest and rate/heart if it did.
Consider the number of the adult tickets is x
X+2x=276
3x=276
X=92
So the student tickets is =184
Well let's see.
The equation has exactly one solution.
Hope this helps.
Answer:
Step-by-step explanation:
Do FOIL, first outside inside last
3x × 3x = 9x^2
3x × -7 = -21x
7 × 3x = 21x
7 × -7 = -49
So it would just be 9x^2 - 49
Answer:
a = 0, b = 3
Step-by-step explanation:
3a + b = 3
b = - 3a +3
2a - 5b = - 15
2a - 5(-3a + 3) = - 15
2a + 15a - 15 = - 15
17a = 0
a = 0
b = -3a +3 = - 3 *0 +3 = 3
