Any answers for this?
Answer:
D(t) = 2,280 - 60t
for D(15) compare the eqns and substitute the value of t.
D(15) = 2,280 - 60(15)
D(15) = 1,380 miles.
In the context of the qn, the Chang family travels 1,380 miles in 15 hours.

Plz help ASAP will mark branliest
Step-by-step explanation:
Consider that:
[tex](f/g)(x) = f(x) / g(x)\\(f - g)(x) = f(x) - g(x)[/tex]Fill in the blanks
Row 1 ⇒ 2 and -5
(-1)*(-2) = 2Solve using two values:
f(x) - g(x) = - 10 and f(x)/g(x) = - 1 ⇒ f(x) = -g(x), substitute into first-2g(x) = - 10 ⇒ g(x) = 5 and f(x) = - 5Row 2 ⇒ -5 and 5
- 2 - 3 = - 5g(x) = 5 (see above solution)Row 3 ⇒ - 6 and 4
-10 - (-4) = - 62 - (-2) = 4Row 4 ⇒ -6/7 and 2/5
-6/7-2/-5 = 2/5alguien que me diga como se saca la X en ecuaciones cuadraticas porfaaaaaaaaa

What is the resulting expression?
O2k4-10K2-7k-14
O-1062-7k+244-14
0 -17k2+10k4-14k-14
O 6k4-14k2 +7k-14
Answer:
-7k
Step-by-step explanation:
(−102+7k+6×4)+(−14−464−14k)
Multiply 6 and 4 to get 24.
−102+7k+24−14−464−14k
Add −102 and 24 to get −78.
−78+7k−14−464−14k
Subtract 14 from −78 to get −92.
−92+7k−464−14k
Subtract 464 from −92 to get −556.
−556+7k−14k
Combine 7k and −14k to get −7k.
−556−7k

Which relationship is NOT a function?
Answer:
a
Step-by-step explanation:
Answer:
If it is possible to draw any vertical line (a line of constant x) which crosses the graph of the relation more than once, then the relation is not a function. If more than one intersection point exists, then the intersections correspond to multiple values of y for a single value of x (one-to-many).

a journey by bus takes 45 mins at 40km/h how fast must a car go to undertake the same journey in 25 mins
Answer:
72km/h
Step-by-step explanation:
Bus - 45 mins at 40km/h
Car - 25 mins at ?
First, find the distance travelled by the bus (since, the journey of the two vehicles are the same, the distance would be the same as well)
distance = speed × timedistance = 40 × 3/4 (45 mins = 3/4 of an hour (45 ÷ 60))distance = 30kmNow we can find the speed of the car using the equation
speed = distance ÷ timespeed = 30 ÷ 5/12 (25 mins = 5/12 of an hour (25 ÷ 60))speed = 72km/hplz help

Write the following as an algebraic expression.
Subtract 3x + 5 from 6x-8.
The answer is
(Simplify your answer.)
Answer:
-0.002
3x+5=6x-8
Answer:
x=1.4
Step-by-step explanation:
6x-8 -3x+5
+3x +3x
So now we have: 9x-8 5 so add 8 on both sides, leaving you with 9x on one and 13 on the other. Now divide 13 by 9, which is 1.4_ so x=1.4
Now do 3 times 1.4 plus 5 and 6 times 1.4 minus 8 and the results you get for each you will need to subtract: (result of 6x-8) - (result of 3x + 5)
