Answer:
a) 20
Step-by-step explanation:
2 hours at 50 km/h means she went 100 km
so 100/5= 20km/hr
Tan B=1.33. If you put tan^-1 and find the angle of A, you’ll get 36.87, so 90-36.87=53.13, then put Tan53.13, you’ll get TanB=1.33
Answer:
i would say either F or G
i guess choose F
Answer:
y = 5x + 4
Step-by-step explanation:
First I found the slope by using the the definition that slope is rise/run so I saw that the y value went up from 4 to 9 which is 5 units and then the x value went up one in that same time. This means that the slope is 5/1. Then I found the y intercept by seeing where x = 0. On the graph you can see the line touches the y - axis at a value of 4 which means that the y - intercept is 4. Plugging these values into the y = mx + b equation you get y = 5x + 4.
Answer:
9x - 8
Step-by-step explanation:
the perimeter is the sum of the sides, hence
perimeter = 5x - 2 + 3x + 4 + x - 10 ( collect like terms )
= 9x - 8 ← polynomial of degree 1
