Answer:
C. 7t
Step-by-step explanation:
What we know:
We are looking for an expression equal to 4t + 3t.
There are 4 choices:
1. 7t²
2. 7 + 2t
3. 7t
4. 12t
The answer does end in t, but is only one term, so B is eliminated.
An exponent is not involved either, so A is also eliminated.
It shows an addition sign, not multiplication, so D is also out.
This leaves C, which is 7t.
Doing this mathematically, add like terms.
4t + 3t
7t

Together a chair, a table, and a lamp cost $562. The chair costs 4 times as much as the lamp, and the table costs $23 less than the chair. Find the cost of the table.
Answers
Answer:
Cost of table is $237
Step-by-step explanation:
Cost of chair, table and lamp = $562
Cost of lamp = x
Cost of chair = 4x (The chair costs 4 times as much as the lamp)
Cost of table = 4x-23 (the table costs $23 less than the chair.)
We need to find the cost of table.
We know that:
Cost of chair, table and lamp = $562
We can write:
[tex]x+4x+4x-23=562[/tex]
First, we need to find value of x by solving the equation.
[tex]x+4x+4x-23=562\\9x=562+23\\9x=585\\x=\frac{585}{9}\\x=65[/tex]
So, we get x = 65
Now, we can find cost of table:
We are given:
Cost of table = 4x-23
Cost of table = 4(65)- 23 = 237
So, Cost of table is $237
Ben starts walking along a path at 3 mi/h. One and a half hours after Ben leaves, his sister Amanda begins jogging along the same path at 5 mi/h. How long (in hours) will it be before Amanda catches up to Ben?
Answers
Answer:
2 hours 15 minutes
Step-by-step explanation:
Given that :
Ben's speed = 3 mi/hr
One and half hours after Ben leaves = 1.5 hours
Ben's distance = 3 mi/hr * 1.5 = 4.5 miles
Amanda's speed = 5 mi/hr
Time taken before Amanda catches up:
Let time taken = x
Distance = speed * time
Ben's distance = Amanda's distance
4.5 mi + (3 * x) = 5 * x
4.5 + 3x = 5x
4.5 = 5x - 3x
4.5 = 2x
x = 4.5 / 2
x = 2.25 hours
Time taken = 2.25 * 60 = 135 minutes = 2 hours 15 minutes
It would take Amanda 2.25 hours to catch up with Ben
Speed is the ratio of distance to time. It is given by:
Speed = distance/time
Given that Ben covers a distance d at time t, hence:
3 = d/t
d = 3t
Since Amanda leaves One and a half hours (1.5) after Ben leaves, hence Time = t - 1.5
5 = d/(t - 1.5)
d = 5t - 7.5
Since they catch up, hence:
3t = 5t - 7.5
2t = 7.5
t = 3.75 hours
Time for Amanda = t - 1.5 = 3.75 - 1.5 = 2.25 hours
Hence it would take Amanda 2.25 hours to catch up with Ben.

The depth of an underwater camera on a cable anchored to the sea floor is proportional to the time. The table records the time in seconds (s) and depth in meters (m) of the camera. What are the missing values in the table?
Answers
Answer:
20=-1
60=-3
100=-5
240=-12
Step-by-step explanation:
divide time and depth by 20
When time is 20 the depth is -1, when time is 60 the depth is -3 and time is 240 the depth is -12.
What is Ratio?A ratio is an ordered pair of numbers a and b, written a / b where b does not equal 0.
The depth of an underwater camera on a cable anchored to the sea floor is proportional to the time.
From the table let us take the values of time and depth which both are given.
Time=100 and depth is -5.
From this we can find the other values.
Depth=-1 when time is x
100/-5=x/-1
100=5x
Divide both sides by 5
x=20
So when time is 20 the depth is -1.
Now we have to find the depth when time is 60.
60/x=100/-5
-300=100x
x=-3
So when time is 60 the depth is -3.
Now we have to find the depth when time is 240.
240/x=100/-5
-1200=100x
Divide both sides by 100
x=-12
when time is 240 the depth is -12.
Hence, when time is 20 the depth is -1, when time is 60 the depth is -3 and time is 240 the depth is -12.

Find the general solution of
dy/dx + 2y =6
Answers
Answer:
ye^(2x) - 3e^(2x) = C or (y - 3)e^(2x) = C
Step-by-step explanation:
dy/dx + 2y = 6
This is a first order linear ODE.
p(x) = 2
Integrating factor: I(x) = e^(∫ 2 dx) = e^(2x)
e^(2x)(dy/dx + 2y) = 6e^(2x)
e^(2x) dy + 2ye^(2x) dx = 6e^(2x) dx
Integrate both sides of the equation.
ye^(2x) = 3e^(2x) + C
Thus, the general solution is ye^(2x) - 3e^(2x) = C or (y - 3)e^(2x) = C.

what is the slope intercept form of the equation of the line?
Answers
Answer:
The slope-intercept form of the equation of the line is:
y = 2/3x + 2
Step-by-step explanation:
The slope-intercept form of the line equation
y = mx+b
where
m is the slopeb is the y-interceptGiven the points
(0, 2)(3, 4)(x₁, y₁) = (0, 2)
(x₂, y₂) = (3, 4)
Using the formula
Slope = m = [y₂ - y₁] / [x₂ - x₁]
= [4 - 2] / [3 - 0]
= 2 / 3
Thus, the slope of the line = m = 2/3
We know that the value of the y-intercept can be determined by setting x = 0 and determining the corresponding value of y.
From the graph, it is clear
at x = 0, y = 2
Thus, the y-intercept b = 2
now substituting m = 2/3 and b = 2 in the slope-intercept form
y = mx+b
y = 2/3x + 2
Therefore, the slope-intercept form of the equation of the line is:
y = 2/3x + 2
