It's a geometric sequence with a first term of 16 and a common ratio of 10, it's rule or function is:

f(n)=16(10^(n-1)) or if you prefer...

f(n)=1.6(10^n)

The pattern is, you just add a zero to each!

The symbol "<=" without quotes means "less than or equal to"

-6x + 2y <= 42
-6x + 2y + 6x <= 42 + 6x ... Add 6x to both sides
2y <= 6x + 42
2y/2 <= 6x/2 + 42/2 ... divide every term by 2
y <= 3x + 21

So the answer is choice D

Find the highest common factor (H.C.F) OF 168 and 252.

blondinia [14]

Let's first write all the factors of 168 and 252.

168 - 1,2,3,4,6,7,8,12,14,21,24,28,42,56,84,168
252 - 1,2,3,4,6,7,9,12,14,18,21,28,36,42,63,84,126,252

84 is the GCF because 84 is greatest common factor of 168 and 252.

So, 84 is the GCF

Hope this helps.. :)

Answer:

D. y = 1.5x +5

Step-by-step explanation:

The offered answer choices are equations in slope-intercept form. The constant in the equation is the y-intercept, the value of distance when time is zero.

y = mx +b . . . . m is slope; b is y-intercept

The table tells you that the distance value is 5 when the time value is 0. In the equation, that means ...

b = 5

Only one answer choice matches:

y = 1.5x +5
