Answer:

HCF×LCM=a×b

6×60=a×b

a×b=360

So the numbers are whose product is 360 and LCM is 60

These two numbers can be 6,60 or 12,30

The value of a collector’s item is expected to increase exponentially each year. The item is purchased for $500. After 2 years,

Andreyy89

Y = 500(1 + r)^x; where r is the rate and x is the number of years.
500(1 + r)^2 = 551.25
(1 + r)^2 = 551.25/500 = 1.1025
1 + r = sqrt(1.1025) = 1.05

Therefore, the equation that represents y, the value of the item after x years is
y = 500(1.05)^x

SPIDER ~ HNYCMB<br> Find NY, YC, CM, AND MB.

zzz [600]

Answer:

HN = 66, NY = 27, YC = 30, CM = 27, MB = 42,

Step-by-step explanation:

When comparing the two shapes, SPIDER is 0.75 times larger than HNYCMB. Besides this small detail they are the same shape. We can determine this by identifying which sides are most similar and dividing them, if SP "=" HN, then to find the rate at which figure HNYCMB shrank is to divide SP by HN. 66/88 is 0.75. By multipying the sides of figure SPIDER by 0.75, we get our answers.

HN ~ SP, 66 = 88 * 0.75, HN = 66

NY ~ SR, 27 = 36 * 0.75, NY = 27

YC ~ RE, 30 = 40 * 0.75, YC = 30

CM ~ ED, 27 = 36 * 0.75, CM = 27

MB ~ DI, 42 = 56 * 0.75, MB = 42

BH ~ PI, BH = ? Try this one by yourself for understanding

A line contains the points (3,9) and (-1,1) what is the equation of the line?

kirza4 [7]

To find the equation of a line using two given set of points, you must first find slope. To do so, we must use the slope formula:
y2 - y1 / x2 - x1

In this case:
1 - 9 / -1 - 3 = -8 / -4
- 8 / -4 = 2 (simplified)

Now we can use the point-slope formula:
y - y1 = m(x - x1)

y - 1 = 2(x + 1 )
y - 1 = 2x + 2
y = 2x + 3

In order to make 3x - y = 6 in slope intercept form, we must isolate y.

- y = -3x + 6
Note: y cannot be negative, so we'll multiply both sides by -1
( -1 ) - y = - 3x + 6 ( -1 ) = y = 3x -6
