A point is written using the form (X,Y), so the first number is the X and the second number is the Y.
Replace x and Y in the given equation with the given point:
y ≤ 3x+1
9 ≤ 3(2) +1
9 ≤ 6 +1
9 ≤ 7
9 is not less than or equal to 7, so the point (2,9) does not satisfy the inequality.
-3, -1, 0, 5, 7 ......... hope this helps
Answer:
3,20 is on the graph
Step-by-step explanation:
It is 3,20 because when you look at 3, then look up to 20, the line is exactly where it would intersect
we can simply put both fractions with the same denominator, and thus then we can just compare which numerator is larger.
we can do so by <u>multiplying each fraction by the other's denominator</u>, let's proceed.
This will not factor so you can use the quadratic formula
x = [- (-3) +/- sqrt(9 - 4*5*-4) / 10
= (3 +/- sqrt 89) / 10
= 3 + 9.434 / 10 or 3 - 9.434 / 10
= 1.24 , -0.64 to the nearest hundredth
