Hi there!
The general form of the equation of a line in slope-intercept form is
y = ax + b
With 'a' representing the slope of the line. We know that the slope of this line is 1/4, so we can plug in this value into the equation of the line.
y = 1/4 x + b
When the line passes through the point (0,0) we can also plug in the x- and y-coordinate into the equation, and we'll see that some easy algebra will help us find our solution.
0 = (1/4) * 0 + b
First switch sides
(1/4) * 0 + b = 0
Multiply
0 + b = 0
b = 0
Now we've found our value of 'b', which we can plug back into the equation in slope-intercept form to find our final solution.
y = 1/4 x
or
f(x) = 1/4 x
~ Hope this helps you!
Answer:
e=14
Step-by-step explanation:
15/21 =10/e
by cross multiplying,
e×15=21×10
15e=210
e=210/15
e=14
Counterexample: 27 is divisible by 3 but is not divisible by 6
Answer:
5.97
Step-by-step explanation:
If the radius of the circle = r then
pi r^2 = 56
r^2 = 56/pi
r = sqrt(56/pi)
The radius of the circle is equal to half of a diagonal of the square. That is,
r = (1/2) sqrt (2x^2)
= x (sqrt 2)/2
= x/(sqrt 2)
So x = r sqrt 2
= sqrt (56/pi) sqrt 2
= 4 sqrt (7/pi)
= 5.9708
