Hello from MrBillDoesMath!
Answer:
The second choice
Discussion:
The first choice is not a polynomial because it contains sqrt(x)
The third choice is not a polynomial because it contains (1/x)
The fourth choice is not a polynomial because it contains x in the exponent (ie. 5^x)
Thank you,
MrB
Use synthetic division. -5 in the corner, and then the terms 1 -6 -42 and 79.
Incomplete question but the comnplete question is how long will it take the object to travel 4 4/5km
Answer: time taken for the object to travel = 0.47 hrs
Step-by-step explanation:
Step 1 -- The formulae to represent the relationship of speed, distance and time .
Speed = Distance / Time
Where Speed = 10 1/5 km/h
Distance = 4 4/5 km
Step 2 --- Solving
Time = Distance / Speed
= 4 4/5 km / 10 1/5 km/h
= 24/ 5 x 5/ 51 = 24/51 =0.47 hrs
0r
4. 8 / 10.2 = 0.47 hrs
Therefore the time taken for the object to travel = 0.47 hrs
Answer:
A)
Step-by-step explanation:
Slope of the line:
Plug in x and y values of any of the points.
Equation of the line:
Subtract 3x from both sides:
A is correct.
Answer:
x = 5
Step-by-step explanation:
To get the value of x we will use similar triangles as shown;
AT/AG = AB/AC
9/3 = x+10/3x-10
Cross multiply
3(x+10) = 9(3x-10)
3x + 30 = 27x - 90
Collect like terms
3x - 27x = -90 - 30
-24x = -120
x = 120/24
x = 5
Hence the value of x is 5
