What is the equation of the function that is graphed as line b?y = 1/2x - 1
y = 2x + 1
y = 1/2x + 1
y = -4x
Answers
Answer 1
Answer:
-- Look at the places where the line crosses the 'x' axis and the 'y' axis.
Between those two points, it goes forward 2 units, but only rises 1 unit.
So the slope of the line is 1/2 .
-- Look again at the point where the line crosses the y-axis.
At that point, y=1 .
That's the "y-intercept".
Now you have the slope and y-intercept of the line.
The equation of ANY straight line is
y = (slope)x + (y-intercept) .
You know what they both are, so you can easily write
y = 1/2 x + 1 .
Is that one of the choices ?
Yes it is.
Good enough for me.
That must be the correct one.
With no "blah blah blah" required.

You know it is a right triangle if it has a right angle in it.

0.0175, 0.65, 0.876
The smallest among these is 0.0175
after the decimal point, we see that in 0.0175 the tenth value is 0
in 0.65 the tenth value is 6
and in 0.876 the tenth value is 8
So from smallest to biggest(if needed)
0.0175, 0.65, 0.876

20cm=diameter
perimiter of this one is (pi times radius^2)divided by 2+ 20
diameter=2radius
radius=diameter times 1/2
diameter=20
20/10=radius=10
3.14 times 10^2=314
314 times 1/2=157
157+20=177 cm
perimiter=177 cm

The answer is 1.) 6^1/6
The third root of something is the same as an exponent to the 1/3 power.
(When an exponent is a fraction, the numerator is powers and the denominator finds the root. For example: 3 to the power of 4/2 is multiplied by itself 4 times (81) then the denominator, 2, means we find the square root of it (9). 4/2=2, and 3 to the 2nd power is also 9.)
So that would be 6 to the 1/3 power, then you find the square root of that, so it's (6 to the 1/3 power) to the 1/2 power, and according to the Power Rule (a power on top of a power means you multiply the two powers), that would end up being 1/6.
![\sqrt{ \sqrt[3]{6} } = \sqrt{ {6}^{ (1)/(3) } } = (6 { (1)/(3) })^{ (1)/(2) } = {6}^{ (1)/(3) * (1)/(2) } = {6}^{ (1)/(6) }](//tex.z-dn.net/?f=%5Csqrt%7B%20%5Csqrt%5B3%5D%7B6%7D%20%7D%20%3D%20%5Csqrt%7B%20%7B6%7D%5E%7B%20%5Cfrac%7B1%7D%7B3%7D%20%7D%20%7D%20%3D%20(6%20%7B%20%5Cfrac%7B1%7D%7B3%7D%20%7D)%5E%7B%20%5Cfrac%7B1%7D%7B2%7D%20%7D%20%3D%20%7B6%7D%5E%7B%20%5Cfrac%7B1%7D%7B3%7D%20%5Ctimes%20%5Cfrac%7B1%7D%7B2%7D%20%7D%20%3D%20%7B6%7D%5E%7B%20%5Cfrac%7B1%7D%7B6%7D%20%7D)
