Answer:

x = 1/3

Step-by-step explanation:

1/2 + X = 5/6

collecting the like terms

X = 5/6 - 1/2

making one fraction on the left side by taking the common denominator

X = (5 - 3)/6

X = 2/6

devide the numerator and denominator by 2, you get

X = 1/3

a student found the slope of a line that passes through the points (-3,10) and (5,-7) to be 3/8. what mistake did he make?

Yuki888 [10]

Slope = (y2 - y1) / (x2 - x1)
slope = (-7-10) / (5 - (-3)
slope is supposed to be -17/8
I am guessing she made her mistake by adding a negative sign...the student did : (-7 - (-10) / (5 - (-3) = (-7 + 10) / (5 + 3) = 3/8

Answer:

0.43

Step-by-step explanation:

To calculate the relative frequency of any of the values in the frequency table, divide the value by the total (120)

For example, the relative frequency of boys who prefer math is:

43 ÷ 120 = 0.36

Reading from the frequency table, the total number of boys is 52. Therefore, the relative frequency for the total number of boys is:

52 ÷ 120 = 0.43

Finding an Equation of a Tangent Line In Exercise, find an equation of the tangent line to the graph of the function at the give

Doss [256]

Answer:

$y=3x-3$

Step-by-step explanation:

We are given that

$y=ln x^3$

Point (1,0)

We have to find the equation of tangent line to the given graph.

Differentiate w.r.t x

$\frac{dy}{dx}=\frac{1}{x^3}\times 3x^2}=\frac{3}{x}$

$\frac{d(lnx)}{dx}=\frac{1}{x}$

Substitute x=1

$m=\frac{dy}{dx}=3$

Slope-point form:

$y-y_1=m(x-x_1)$

$x_1=1,y_1=0$

By using this formula

The equation of tangent to the given graph

$y-0=3(x-1)=3x-3$

$y=3x-3$
