Answer:
1. After rearranging the formula as 's' i.e speed is the subject will be given as
.
2. The average speed of a truck that travels a journey of 748 km in 11.5 hours is 65.04 kilometre per hour.
Step-by-step explanation:
Ans 1. subject means it come first in the sentence, hence here question is like write speed first in the formula so we have
Ans 2.
Given :
Total distance of a journey = 748 km
Total time taken for the journey = 11.5 h
To Find:
Average speed =?
Solution :
average speed is defined as of total distance covered divided by total time taken.
So, we have
Summing complex numbers is easy: you just sum the real parts together and the imaginary parts together:
So, you have
Divide the top and bottom by 5
answer = 7/6
Answer:
The answer is "A regular hexagon inscribed in a circle" I also took the practice exam and got it right.
Oops I keep on commenting the answers instead of adding it in as an answer lol.
Answer:
The equations in the slope-intercept form
y = - 2 x + 5
y = - 2 x + 3
Step-by-step explanation:
The slope-intercept form of the linear equation is y = m x + b, where
- m is the slope of the line.
To put any equation in the slope-intercept form state y on the left side, x and the numerical term on the right side, the coefficient of y must be 1.
Let us do that with the given equations
∵ 2x + y = 5
→ Subtract 2x from both sides to move x to the right sides
∴ 2x - 2x + y = 5 - 2x
∴ y = 5 - 2x
→ Switch 5 and - 2x
∴ y = - 2x + 5
∵ 3y = 9 - 6x
→ Divide each term by 3 to make the coefficient of y = 1
∴
∴ y = 3 - 2x
→ Switch 3 and - 2x
∴ y = - 2x + 3
The equations in the slope-intercept form
y = - 2x + 5
y = - 2x + 3
