Subtraction property
x+5<32
subtract 5 on both sides
x<27
Answer:
Step-by-step explanation:
a₁₂ = a₅ + (12-5)d
72 = 23 + 7d
d = 7
a₃ = a₅ + (3-5)d = 23 - 2⋅7 = 9
a₂ = a₃ - d = 9-7 = 2
a₁ = a₂ - d = 2 -7 = -5
7pi/6 is in quadrant IV so we know the signs are (-,-)
It has the same terminal point as pi/6.
(- (Sqrt3)/2, - 1/2)
Answer:
b
Step-by-step explanation:
In y=mx+b form, the b is the y-intercept, therefore where the line crosses the y-axis on the graph. In this graph, the line crosses the y-axis at 100. This means that the "b" value is 100. So far, our equation is y=mx+100.
Next, to find m, you go to any other point on the graph and see how much units (rise over run) you went to get there. I picked the point (2,150), You can see that it took me 1 unit up and 2 units to the right to get to that point, leading us to believe the slope is 1/2.
Finally, put everything together and you get the answer of y=1/2x+100 (the letters do not matter) :)
Answer:
a) 80%
80/100 *100 = 80%
b) 10 %
