Answer:
B. Trinomial
Step-by-step explanation:
A trinomial has three terms
The three terms are 2x^2, 3x, -2
Use substitution to find out
x=2
y=3
so
3=3(2)-4
3=6-4
3≠2
no, this point does NOT lie on the graph of y=3x-4
The percent change in Ryan’s weight was 4.2/7, or 60%. The percent change in Amanda’s weight was 6.9/6 , or 115%. Amanda had a greater percent increase in weight.
Answer: A -11
Step-by-step explanation:
its quite simple
subract 9(-) from negative 2
Answer:
X ≤ -3
X > 2
Step-by-step explanation:
3x+7 ≤ -2
-7 in both sides
3x ≤ -9
/3 on both sides
X ≤ -3
5x-1>9
+1 on both sides
5x>10
/5 on both sides
X>2
To graph the solution for the first in you would draw a solid line on x=-3 and shade everything to the left of it
To graph the second one you would draw a dotted line on x=2 and shade everything to the right of it
