Answer:

√125

Step-by-step explanation:

(0,0) (10,5)=(x1,y1) (x2,y2)

√(x2-x1)²+(y2-y1)²

√(10-0)²+(5-0)²

√10²+5²

√100+25

√125

Answer:

y = $\frac{1}{2}$ x

Step-by-step explanation:

identify two points on the line: (2, 1) (4, 2) to find the slope( $\frac{y2 - y1 }{x2 - x1}$ ) for the line

=> $\frac{2- 1}{4-2}$ => $\frac{1}{2}$

find the y-intercept:

=> 0

substitute the slope and y-intercept into the equation y = mx + b

slope ↑ ↑ y-intercept

=> y = $\frac{1}{2}$ x + 0

=> y = $\frac{1}{2}$ x

Answer:

$\frac{1}{3}$

Step-by-step explanation:

Given

- $\frac{1}{4}$ × - $\frac{4}{3}$ ( negative times negative = positive )

= $\frac{1}{4}$ × $\frac{4}{3}$ ( cancel the 4 on the numerator and denominator )

= $\frac{1}{3}$

Write the phrase as an expression. Then evaluate when y=20.

alisha [4.7K]

Answer:

$Q=\frac{40}{y-16}$

$Q=10$

Step-by-step explanation:

Let the quotient be represented by 'Q'.

Given:

The difference of a number 'y' and 16 is $y-16$

Quotient is the answer that we get on dividing two terms. Here, the first term is 40 and the second term is $y-16$ . So, we divide both these terms to get an expression for 'Q'.

The quotient of 40 and $y-16$ is given as:

$Q=\frac{40}{y-16}$

Now, we need to find the quotient when $y=20$ . Plug in 20 for 'y' in the above expression and evaluate the quotient 'Q'. This gives,

$Q=\frac{40}{20-16}\\Q=\frac{40}{4}=10$

Therefore, the quotient is 10, when the value of 'y' is 20.

To attempt this algebraic equation we will be multiplying 4 to (3 - x) bracket so as to form the term on L.H.S.

$:\implies\tt{4(3 - x) = (1 - 2x)}$
