Answer:

C III

Step-by-step explanation:

The rate of change of a linear function is the slope.

f(x) = mx + b is the equation of a linear function whose graph is a straight line. m is the slope.

I f(x) = 4x - 3; m = slope = 4

II f(x) = 1/2 x + 5; m = slope = 1/2

III We can use two points to find the slope.

Let's use points (1, 6) and (2, 12).

m = slope = (y2 - y1)/(x2 x1) = (12 - 6)/(2 - 1) = 6/1 = 6

The three slopes are 4, 1/2, 6.

The greatest rate of change is 6, so the answer is C III.

Adding and subtracting rational expressions

uysha [10]

Answer:

Step-by-step explanation:

When adding or subtracting rational expressions, it is easiest to find a common denominator.

Ex.

$\frac{x+2}{x-5} + \frac{x-7}{x} \\$

The common denominator would be $x(x-5)$

We need to make both fractions have that denominator

$\frac{(x+2)(x)}{(x-5)x} + \frac{(x-7)(x-5)}{x(x-5)} \\\frac{(x^2+2x)+(x^2-12x+35)}{(x^2-5x)}\\\frac{2x^2-10x+35}{(x^2-5x)}$

Estimate the fraction 3/8 by rounding to the nearest whole or one-half

Fittoniya [83]

SOLUTION

The fraction given is

$\frac{3}{8}$

To round-off the fraction, we need to convert it to decimal number

$\frac{3}{8}\text{ to decimal is }$

Hence

The estimated fraction in decimal will be

$0.375=0.4=\frac{4}{10}=\frac{2}{5}$

the sum of the angle measures in a triangle is 180 degrees. two angles of a triangle measure 30 degrees and 70 degrees. what is

makvit [3.9K]

third angle = 80°

to find the third angle, add the 2 given angles and subtract from 180

third angle = 180° - (30 + 70 )° = 180 - 100 = 80°
