Yes it does but you have to rearrange it so that it says y=mx+b
Answer:
14. 36
15. 12.5
16. 2.5
17. -34,359,738,368
Step-by-step explanation:
14.
F(2) = 6^2
= 36
15.
G(-2) = 2*.4^-2
= 2*1/.16
= 2/.16 or 1/.08 or 12.5
16.
y = 20*.5^3
= 20*.125
= 2.5
17.
H(w) = -0.5*4^18
= -34,359,738,368
Answer:
14 miles.
Step-by-step explanation:
Let the distance traveled from home to destination = x miles.
Speed while going to friend's house = 35 miles per hour.
Speed while coming back = 40 miles per hour.
Total Time taken for the journey = 45 minutes = 0.75 hours.
Let the time taken while going to friend's house = y hours.
Therefore, the time taken while going to friend's house = (0.75 - y) hours.
To find x and y, model the speeds of both the journeys.
Speed while going to friend's house = Distance/Time.
35 = x/y.
x = 35y (Equation 1).
Speed while coming back = Distance/Time.
40 = x/(0.75 - y).
x = 40(0.75 - y) (Equation 2).
Since x = x, therefore:
35y = 30 - 40y.
75y = 30.
y = 30/75.
y = 0.4 hours.
Put y = 0.4 hours in Equation 1:
x = 35y.
x = 35(0.4).
x = 14.
Therefore, the distance between my friend's house and my house is 14 miles!!!
For the above figure, the formula is,
x² = WY (YV + WY)
WY = 5
YV = 12
Substituting in the above formula,
x² = 5 x (12 + 5)
x² = 5 x 17 = 85
x² = 85
⇒ x = √85 = 9.21954 = 9.220
