2x-12 = 18
+12 +12
2x=20
20/2 = 10
Answer:
24
Step-by-step explanation:
Original equation:
2x - 12 = ?
We know x = 18
So, just plug the value into the equation
2(18) - 12
Multiply 2 by 18
36
Subtract 12 from 36
The answer is 24

Lola runs at a constant speed of 3.4 meters per second for 1/2 hour.then she walks at a rate of 1.5 meters per second for 1/2.how far did Lola run and walk in 60 minutes?
Answer:
8,820m
Step-by-step explanation:
Let m be meters
We will have to find the amount of seconds in half an hour
60 * 30
= 1,800
Then we will multiply the meters she walks per second by 1,800
3.4m * 1,800
= 6,120m
1.5m * 1,800
= 2,700m
We add those two together to get the total walked in an hour
6,120m + 2,700m
= 8,820m

Write a unit rate for the situation.
$12.50 for 5 ounces
$__ per ounce
Answer:
The correct answer is $2,50.
Step-by-step explanation:
The unit rate is what we use to determine the price of a single unit, when something is sold in a group, as in this case 5 ounces.
We have been told that $ 12.50 is the price for 5 ounces, but what we want to know is how much 1 ounce costs.
To determine this, what we must do is divide the total price by the quantity of ounces, in order to determine the unit price:
12.50 / 5 = 2.50
In this way we can verify that the unit price of 5 ounces is $ 2.50

Consider these functions: f(x)=x+1, g(x)=2/x
Which polynomial is equivalent to (fog)(x)?
A.2/x+1
B.2x+2/x
C.2/x +1
D.2/x^2+x
Answer:
A.2/x+1 ............
The composite function f(g(x)) is 2/x + 1
Given the function
f(x)=x+1g(x)=2/xWe are to get the composite function (fog)(x)
This can be written as:
f(g(x)) = f(2/x)
f(2/x)= 2/x + 1
Hence the composite function f(g(x)) is 2/x + 1

[tex]x + y = 8 \\ x - y = 10[/tex]
Answer:
The solution is x = 9, y = -1.
Step-by-step explanation:
x + y = 8
x - y = 10 Adding to eliminate y:
2x + 0 = 18
x = 9 Substituting x = 9 into the first equation:
9 + y = 8
y = 8 - 9
y = -1..
During a regular respiratory cycle, the volume of air in liters in the human lungs can be described by the function V(t) = 0.173t +0.15t^2 - 0.035t^3 where t is the time in seconds. Estimate the time in seconds from the beginning of this respiratory cycle for the lungs to fill to their maximum volume of air. a. about 3.4 seconds b. about 4.4 seconds c. about 5.4 seconds d. about 10.4 seconds
Answer:
A. about 3.4 secondsStep-by-step explanation:
Given the volume of air in liters in the human lungs described by the function V(t) = 0.173t +0.15t^2 - 0.035t^3 where t is the time in seconds,
The beginning of this respiratory cycle for the lungs to fill to their maximum volume of air occurs when dV/dt = 0
dV/dt = 0.173 + 0.3t - 3(0.035)t²
dV/dt = 0.173 + 0.3t - 0.105t²
Since dV/dt = 0
0.173 + 0.3t - 0.105t² = 0
multiply through by -1
-0.173 - 0.3t + 0.105t² = 0
0.105t² -0.3t-0.173 = 0
Factorize;
t = 0.3±√0.3²+4(0.105(0.173))/2(0.105)
t = 0.3±√0.09+0.07266/0.21
t = 0.3±√0.16266/0.21
t = 0.30±0.4033/0.21
t = 0.7033/0.21
t = 3.349secs
t ≈ 3.4secs
Hence it will take about 3.4secs for the lungs to fill to their maximum volume of air

Answer:
Step-by-step explanation:
I can't really graph it for you, but I will show you how to.
-x is the value on the horizontal axis, which are 1,2,3,4,6
if you replace x for 1, which is
y= -4(1) + 3
y= -1
so you can graph that point (1,-1)
you can replace x with other numbers on the horizontal axis.
