By looking at the scatter plot we can predict that the answer will be higher than previous answers since there is a positive relationship between x and y. With this idea, we can determine that a. is not the answer. Since it is too small of a y value. It also can't be b or c since these values are also small. Therefore the answer is d, for an x value of 200 the y value should be 555.5 from the choices given.
Answer:
49
Step-by-step explanation:
Every time you multiply both sides of a rectangle by a number x, its area if multiplied by .
In our example:
Area of a rectangle = width . length
width = 4
length = 7
= 4 . 7 = 28
When you multiply both sides by 7:
width = 4 . 7 = 28
length = 7 . 7 = 49
= 28 . 49
= 1372
/
= 1372 / 28 = 49 =
Both sides multiplied by 7 => Area multiplied by
Got it?
