Answer:
D Option is the correct one.
Step-by-step explanation:
As,
Distance covered = 40km = 40000m(1k=1000m)
time = 10:15-9:00 = 1:15hours = 75mins
We need to find the rates of the bicyclist in one hour so, for this first we need to calculate the total distance which covered in one hour.
For calculating distance for one hour,
40000/75 = 533.33m/min (means they covered 533.33m distance in one min)
for one hour:
533.33*60= 32000m = 32km
They covered 32km distance in one hour.
Now from the given options D is the correct one because according to give condition north bicyclist covered 4km more that south one. And other reason is we also need to check the sum of distance covered by the both cyclist which must be equal to 32km.
So for A,
Sum = 19 + 15 =34 (wrong not equal to 32)
For B,
Sum = 18 + 13 = 31 (wrong)
For C,
Sum = 16 + 10 = 26(wrong)
For D,
Sum = 18 + 14 = 32 (Right)
And second distance b/w both distance is 4km.
18-14 = 4(Right)
So, D option is the right one.

Answer: 126
Step-by-step explanation:
11+5=16

square root of 121 is 11 and cube root of 125 is 5 i.e
11^2=121 and 5^3=125
Solve the simultaneous equation
3x-4y=11
9x+2y=5
Answer:
I assume you are looking for the x and y values of the two equations? if not message me!
y=–2
x=1
Step-by-step explanation:
Multiply the first/top tearm by –3 so we can "get rid of" the X's with the addition of both equations. we are then left with: 14y=-28
We can now divide both sides by 14 to get y by itself so we are left with: y=–2
plugging our y value back into the first equation we get: 3x+8=11. we subtract 8 from both side and are left with: 3x=3. dividing both side by 3 we can get x by itself and are left with: x=1
To check, we plug x and y both into the first equation we get: 3+8=11 (which it does). Or we can plug both of them into the second equation and we get:9-4=5 (which it does)
Answer:
Below in bold.
Step-by-step explanation:
3x-4y=11
9x+2y=5
Multiply the first equation by 3:
9x - 12y = 33
Subtract the above from the second equation:
2y - (-12y) = 5 - 33
14y = -28
y = -2.
Now plug y = -2into the first equation:
3x - 4(-2) = 11
3x = 11 - 8 = 3
x= 1.

how to slove and answer 11r+60=16
Answer:
r= -11
Step-by-step explanation:
11r + 60=16
we can see that 11x r + 60 = 16
but thats the problem ! we don't know what r is so
lets get r on its own
11r + 60 =16
subtract 60 from each side
60 -60 =0
left side = 11r
16-60 = -44
right side = -44
11 r = -11
divide both sides by 11
11r divided by 11 = r
-44 divided by 11 = -11
r=-11

The points (0, 0) and (5, 10) lie in the graph of this linear function. Which equation represents the same linear function? A. B. x = 5 C. D. y = 2x
Answer: y = 2x, D.
Step-by-step explanation: We can calculate the slope of the line between these two points: Rise/Run:
Rise: (10-0)=10
Run: (5-0) = 5
Rise/Run = 10/5 = 2
The y-intercept is zero (it is the value of y when x=0, which we are given as (0,0)).
The line between these two points is thus y=2x+0, or
y = 2x. Looks like D.
Answer:
D. y=2x

Rick buys 3 CDs and 5 video games. The cost of one video game is $12.00 more than the cost of one CD. If Rick spends $164.00, what is the cost of each CD?
Step-by-step explanation:
x = price per video game
y = price per CD
164 = 5x + 3y
and then we know
x = y + 12
now we can use this as substitute in the first equation :
164 = 5(y + 12) + 3y = 5y + 60 + 3y = 8y + 60
104 = 8y
y = $13
x = y + 12 = 13 + 12 = $25
so, each CD costs $13.
How would you write the following expression as a sum or difference?
Answer:
B
Step-by-step explanation:
Look at the expression inside the log( ). Work from the outside in, so to speak. First, there's a quotient (the cube root divided by 3x).
[tex]\log \left( \frac{\sqrt[3]{2-x}}{3x} \right) = \log\left(\sqrt[3]{2-x}}\right) - \log{3x}[/tex]
The cube root can be written using a rational exponent.
[tex]\log\left(\sqrt[3]{2-x}}\right) - \log{3x} = \log \left( (2-x)^{1/3} \right) - \log{3x}[/tex]
Use the exponent property to move the exponent 1/3 out.
[tex]\log (2-x)^{1/3} - \log{3x} = \frac{1}{3} \log{(2-x)} - \log{3x}[/tex]
This now matches answer choice B.

Q; write the sentence as an equation. 251 is equal to 130 added to q
Answer:
251 = 130 + q
This is d equation
Answer:
251 = q + 130
Step-by-step explanation:
251 is equal to 130 added to q,
→ 251 = q + 130
Let's solve the equation,
→ 251 = q + 130
→ q = 251 - 130
→ [ q = 121 ]
So, the answer is 121.

The graph of f(x)=16^x is reflected about the x-axis and shifted upward 8 units. What is the equation of the new function, g(x) ?
Answer:
g(x) = -16^x + 8
Step-by-step explanation:
This reflection is accomplished by putting a negative sign in front of 16^x, and the upward translation by adding 8:
f(x)=16^x becomes g(x) = -16^x + 8

Which choice is the graph of y < x – 5? (Need Help!!!)
Answer:
Step-by-step explanation:
The graph increasing over the given entire interval: -3 < x < 0.
What is Linear Function?An equation can be represented by a linear function. The standard form for the linear equation is: y= mx+b , for example, y=2x+5. Where:
m= the slope.
b= the constant term that represents the y-intercept.
Here, we have,
For the given example: m=2 and b=5.
A function can be classified as:
increasing - when the values of y increase with the increasing of x-values
decreasing - when the values of y decrease with the increasing of x-values
The question gives the entire interval where the function increases. Thus, from the graph is possible to see that the function increases when x is between –3 and 0 because the values of y increase with the increasing of x-values.
Hence, The graph increasing over the given entire interval: -3 < x < 0.

Find missing value to make a function….Thanks
Answer:
12
Step-by-step explanation:
First find the slope
m = ( y2-y1)/(x2-x1)
= ( 60-30)/(6-0)
= 30/6 = 5
Now using a second set of points and the slope we can find p (0,30) and (p,90)
5 = ( y2-y1)/(x2-x1)
5 = (90-30)/(p-0)
5 = 60/p
Multiply each side by p
5p = 60
Divide by 5
p =60/5
p = 12
