Answer:

The coordinate B' is $B' = (3, -3)$ .

Step-by-step explanation:

The new coordinate is computed by applying the scale factor with respect to origin:

$B' = \alpha \cdot B$

$B' = 3\cdot (1,-1)$

$B' = (3\cdot 1, 3 \cdot (-1))$

$B' = (3, -3)$

QUESTION :-

what is the value of x to the nearest whole number?

ANSWER :-

$\cos( \theta) = \frac{base}{hypotenuse} \\ \cos(30) = \frac{x}{24} \\ \frac{ \sqrt{3} }{ \cancel2} = \frac{x}{ \cancel{24}} = \frac{x}{12} \\ 1.732 = \frac{x}{12} \\ 12 \times 1.732 = x \\ x = 20.7$

the nearest whole number-->

20.7 --> approximately --> 21 units

Answer:

Step-by-step explanation:

Put the ordered pairs into the slope formula x=y2-y1/x2-x1 then you will get your slope of the line. once you have your slope pick an ordered pair and put it in point slope y-y1=m(x-x1) distribute and you will get your answer.
