Answer:

5x-y≥ 1

Step-by-step explanation:

Find the slope of the line to be :

y = 5x -1 <===== the shaded area is less than or equal (because it is a SOLID line...not dashed) to this :

y ≤ 5x-1 re-arrange to

5x-y ≥ 1

Answer:

$- 39xy + 12 {y}^{2}$

Step-by-step explanation:

1) Simplify 6x × 2y to to 12xy.

$12xy - 3xy - 24xy \times 2 + 12 {y}^{2}$

2) Simplify 24xy × 2 to 48xy.

$12xy - 3xy - 48xy + 12 {y}^{2}$

3) Collect like terms.

$(12xy - 3xy - 48xy) + 12 {y}^{2}$

4) Simplify.

$- 39xy + 12 {y}^{2}$

Thus, The answer is -39xy + 12y².

3 of the digits 0-9 are chosen randomly by a computer what is the probability that it will choose 3 sequential digits?

Sindrei [870]

Answer:

B. 1/15

Step-by-step explanation:

The number of ways in which we can select x elements from a group of n elements is calculated as:

$nCx=\frac{n!}{x!(n-x)!}$

So, the number of ways in which a computer can select 3 digits is calculated as:

$10C3=\frac{10!}{3!(10-3)!}=120$

Because there are 10 digits from 0 to 9.

Then, from that 120 options there are 8 that have 3 sequential digits. These options are:

{0,1,2} {1,2,3} {2,3,4} {3,4,5} {4,5,6} {5,6,7} {6,7,8} {7,8,9}

So, the probability that it will choose 3 sequential digits is equal to:

$P=\frac{8}{120}=\frac{1}{15}$

The ratio of the sides of two similar octagons is 2:5. What is the ratio of the perimeters of these octagons?

Tom [10]

So we see the ratio of the sides of two similar octagons is 2:5 so let's say the first octagon has a side of 2 and the other has a side of 5. 2*8 = 16 and 5*8 = 40. 16:40 = 4:10 = and is again 2:5. So the answer is 2:5.

A line's y-intercept is 0, and its slope is 6/5. what is its equation in slope-intercept form?

Butoxors [25]

Answer:
y = $\frac{6}{5} x$

Explanation:
The equation of the line has a general formula:
y = mx + c
where:
m is the slope = 6/5
c is the y-intercept = 0

Substitute with the givens in the above formula to get the equation of the line as follows:
y = $\frac{6}{5} x$ + 0
y = $\frac{6}{5} x$

Hope this helps :)
