To make a dot plot, make a numbered line and add dots above the numbers of the given ages. If there are more than one of the same number, add a dot above the dot already there.

Answer:
C = ¼(4B – 7A)
Step-by-step explanation:
⁴/₇(B – C) = A Multiply each side by 7
4(B - C) = 7A Remove parentheses
4B – 4C = 7A Subtract 4B from each side
-4C = 7A – 4B Multiply each side by -1
4C = -7A + 4B Divide each side by 4
C = ¼(4B – 7A)
Answer:
20 km
Step-by-step explanation:
We will imagine a triangle. The hypotenuse of the triangle is the distance between you and the plane. 16 kilometres is the aerial space between you two, in other words its the base of the triangle. 12 km is the length of the third leg of the triangle. We will apply the pythagorean theorem to find the length of the hypotenuse and the distance between you and the plane.
a^2 + b^2 = c^2
12^2 + 16^2 = c^2
144 + 256 = c^2
400 = c^2
square root of 400 is c which equals 20 km.
Answer:
Step-by-step explanation:
Let X= each ticket for adults and Y= each ticket for kids
x+y=548
6.50x+3.50y=2881
subtract x from each side leaving you with y= -x+548
Plug in for Y
6.50x+3.50(-x+548)=2881
6.50x - 3.50x + 1918= 2881
3x+1918=2881 ....subtract
3x=963 .....divide by 3
X= 321 tickets for adults
321+y=548 ...subtract 321
Y=227 childrens tickets
Answer:
7) (f+g) (x) = 4^x + 5x -5
8) (f-g) (x) = 4^x + x - 5
Step-by-step explanation:
7) Find (f +g)(x)
(4^x + 3x + 2x - 5)
(4^x + 5x -5)
(f+g) (x) = 4^x + 5x -5
8) Find (f-g)(x)
(4^x + 3x - 2x - 5)
(4^x + x - 5)
(f-g) (x) = 4^x + x - 5
