Answer:
d = 0.7*t
Step-by-step explanation:
Given data,
Time Distance
10 7
15 10.5
20 14
From analysis,
1) d1/t1 = 7/10 = 0.7
2) d2/t2 = 15/20 = 0.7
3) d3/t3 = 14/20 = 0.7
It can be analysed from the figure that, at every point d/t = 0.7
Therefore, the relationship between t and d is
d = 0.7*t
or
t = d/0.7
Answer:
d=0.7t

I just did the question on khan academy.
Answer:
f(-2) = 50
Step-by-step explanation:
What f(-2) simply means is that you will substitute -2 in f(x) = 8x^2 − 14x − 10.
That is wherever you see x you replace it by 2
f(-2) = 8(-2)² - 14(-2) - 10
= 8(4) + 28 - 10 (note (-2)² = -2 × -2 = 4. Also, -14 × -2 = 28)
= 32 + 28 - 10
= 60 -10
=50
Therefore f(-2) = 50
Answer:
f(- 2) = 50
Step-by-step explanation:
To evaluate f(- 2) substitute x = - 2 into f(x)
f(- 2) = 8(- 2)² - 14(- 2) - 10
= 8(4) + 28 - 10 = 32 + 28 - 10 = 50
2x+4y=14
It breaks down and changes into liquid.
B.
It splits apart and combines with plant roots.
C.
It breaks down and combines with water, air, and organic matter.
D.
It falls apart and combines with particles in the air.
the answer is C, because all different types of rocks (sedimentary, metamorphic, etc.) combine using those different types of things.
