Answer:
A car travels 75 km in 1 hour; we say that the speed of the car is 75 kilometers per hour, so 75 km/hr.
Answer:
Now that the values of m (slope) and b (y-intercept) are known, substitute them into y=mx+b . to find the equation of the line.
y=5/4x+9/4
Step-by-step explanation:
Use y=mx+b to calculate the equation of the line, where m represents the slope and b represents the y-intercept.
To calculate the equation of the line, use the y=mx+b format.
Slope is equal to the change in y over the change in x , or rise over run.
m=(change in y)/(change in x)
The change in x
is equal to the difference in x-coordinates (also called run), and the change in y is equal to the difference in y-coordinates (also called rise).
m=(y2−y1)/(x2−x1)
Substitute in the values of x and y into the equation to find the slope.
m=1−(6)/−1−(3)
Finding the slope m.
m=5/4
Find the value of b
using the formula for the equation of a line.
b=9/4
Answer:
14 out of the total class of 35 are boys
Step-by-step explanation:
35 / 5 = 7
7 * 2 = 14
Answer:
D
Step-by-step explanation:
Because Y=12=4×3
So if you multiply 4×3 you will get 12.
It doesn't matter HOW you do the division. You can use a calculator,
long division, mental math, short division, a slide rule, a Curta, or an
abacus. Every possible method must deliver the same answer. If it
doesn't, then either you made a mistake using it, or else the method
itself doesn't work.
So I'm not going to tell you what method I'm using.
The decimal equivalent of 3 divided by 11 is
0.2727272727... .
In order to be exactly equal to 3/11, the '27's must keep going forever,
and never end.
If you don't have enough time or space on the paper to write an infinite
string of '27's, then you can write some of them and then stop. The more '27's
you write, the closer your decimal will be to 3/11 , so you can get it as close
as you want. But if you ever stop, then it won't be exactly equal to 3/11 .
