Answer:

3y + 3z

Step-by-step explanation:

(y + z)3

As the parenthesis contains 2 different variables, we cannot add them

Distribute (Multiply 3 by y and z)

3y + 3z

This is the simplest that this expression can get

For the straight line defined by the points (3,57) and (5,87), determine the slope ( m ) and y-intercept ( ???? ). Do not round

Sphinxa [80]

Answer: The slope of the line is 15 and y-intercept is 12.

Step-by-step explanation: We are given to find the slope and y-intercept of the straight line defined by the points (3, 57) and (5, 87).

We know that

the slope of a line passing through the points (3, 57) and (5, 87) is given by

$m=\dfrac{87-57}{5-3}=\dfrac{30}{2}=15.$

Since the straight line passes through the point (3, 57), so its equation will be

$y-57=m(x-3)\\\\\Rightarrow y-57=15(x-3)\\\\\Rightarrow y-57=15x-45\\\\\Rightarrow y=15x-45+57\\\\\Rightarrow y=15x+12.$

So, the required equation of the straight line is $y=15x+12.$

Thus, the slope of the line is 15 and y-intercept is 12.

-7/15.
You multiply the numerator and denominator to get -21/45. To simplify, divide each by the greatest common factor, which is three, to get -7/15.

What is 3 2/5⋅2 1/3 ? as a fraction A. 5215 B.6215 C.71415 D.8115

Sunny_sXe [5.5K]

let's firstly convert the mixed fractions to improper fractions and then multiply.

$\bf \stackrel{mixed}{3\frac{2}{5}}\implies \cfrac{3\cdot 5+2}{5}\implies \stackrel{improper}{\cfrac{17}{5}}~\hfill \stackrel{mixed}{2\frac{1}{3}}\implies \cfrac{2\cdot 3+1}{3}\implies \stackrel{improper}{\cfrac{7}{3}} \\\\[-0.35em] ~\dotfill\\\\ \cfrac{17}{5}\cdot \cfrac{7}{3}\implies \cfrac{119}{15}\implies 7\frac{14}{15}$
