Since the rate of descent is a constant this is a linear equation and can be expressed as:
h=vt+b, where h=feet, v=slope or rate, b=y-intercept (y value when x=0 which is the initial height)
h=-2t+b, using the point (3,67) we can solve for b, or the initial height
67=-2(3)+b
67=-6+b
73=b so the initial height was 73 ft and the height equation is then:
h(t)=67-2t so when t=8 you have:
h(8)=67-2(8)
h(8)=67-16
h(8)=51 ft
Answer:
Step-by-step explanation:
You draw a line right down the middle so it makes it to equal triangle
Answer:
(15c + 8)(a + b).
Step-by-step explanation:
15c·(a+b)+8·(b+a)
(a + b) is common to both parts:
= (15c + 8)(a + b).
Answer:
Answers are below.
Step-by-step explanation:
Hope this helps:)
Y=-6x+1
y=-5
plug second equation into first and you get
-5=-6x+1
-6=-6x
-6x=-6
6x=6
x=1
then plug x into first equation and you get that y=-6*1 +1 = -6+1=-5
therefore x=1 and y =-5
