PLEASE ANSWER THIS ASAP !!!!
Y_Kistochka [10]

Answer:

y = (1/2)x + 2

Step-by-step explanation:

Find the slope:

Take the rise over run to find this- For every unit it goes up, it goes two units across, so it will be (1/2)

Find the y-intercept:

This is the value of y where the line intersects the y-axis- (0,2), so 2

Substitute these values in for m and b:

y = mx + b

y = (1/2)x + 2

Hope that helps! :)

Given the mean 71.4 and sample standard deviation 11.5 what is the z-
Elenna [48]

Answer: 1.18

Step-by-step explanation:

Z = (x - mean) / standard deviation

Z = (85 - 71.4) / 11.5

Z = 13.6 / 11.5 = 1.18

If the slope of line L is -2/5, what is the slope of line m so that line l and line m are perpendicular?
ki77a [65]
Perpendicular lines have negative reciprocal slopes. So if the slope is -2/5...to find the negative reciprocal, " flip " the slope and change the sign.
So we flip -2/5 and we get 5/-2...and now we change the sign...and we get 5/2. So our perpendicular slope will be 5/2.

Consider the function.
Mariana [72]

Answer: (2 1/2, 0) (the last option)

Step-by-step explanation:

I guess the function is:

f(x) = (2  1/2) - (3  1/2)*x

now, the rule for f-1(x) that we know is:

f-1( f(x) ) = x.

So if we want to find the x-intercept of f-1(x), we must evaluate it in f(0)

f-1(f(0)) = 0.

And we have that f(0) = (2  1/2) - (3  1/3)*x = 2  1/2

This means that the x-intercept of f-1(x) will be when x= 2  1/2, so the intercept is:

(2 1/2, 0)
