4)C
5)A
6)D
7)-4/3x-1(use formula y=mx+b, m is slope, x and y is the x and y of the one point that is given, b is y-intercept)
8)B
***Slope is the number multiplied with the x and y-intercept is the last number. It's obvious
The answer to this question is 3/8
Answer:
(0,b) from a formula y=mx+b
(0,y) from a graph
Step-by-step explanation:
Answer:
v = 25.98
Step-by-step explanation:
You could do this a number of ways. Some are much longer than others. The shortest way is to use the tangent.
Formula
Tan(theta) = opposite / adjacent
Givens
Theta = 30o
Opposite = 15 km
Adjacent = x
Solution
tan(30) = 15 / v Multiply both sides by v
v*tan(30) = 15 Divide by tan(30)
v = 15/tan(30)
tan(30) = 0.5774
v = 15 / 0.5774
v = 25.98
The answer is b) 45 because it is the number that falls in the center after you order the data. below you can see there’s 3 numbers on each side.
