-10 x 2 + 21x + 10 How do I factor this?

Answers

Answer 1

Answer: $-10x^2+21x+10=\n-10x^2+25x-4x+10=\n-5x(2x-5)-2(2x-5)=\n-(5x+2)(2x-5)$

Which equation describes the same line as y – 3 = –1(x + 5)?A. y = –1x – 5
B. y = –1x – 2
C. y = –1x – 1
D. y = –1x + 8

Answers

Answer:

Option B is correct.

$y= -1x-2$

Step-by-step explanation:

The distributive property says that:

$a \cdot (b+c) = a\cdot b+ a\cdot c$

Given the equation of line:

$y-3 = -1(x+5)$

Apply the distributive property we have;

$y-3 = -1x-5$

Add 3 to both sides we have;

$y-3+3= -1x-5+3$

Simplify:

$y= -1x-2$

Therefore, an equation describes the same line as y – 3 = –1(x + 5) is, $y= -1x-2$

y – 3 = –1(x + 5)

y - 3 = -x - 5

y = -x - 5 + 3

y = -x - 2

answer is B. y = –1x – 2

9 is 60% of what number?

Answers

Lets say 9 is 60% of x
so 9/x= 60/100 or x= 100*9/60=15
so 9 is 60% of 15.

A florist uses 200 lilies to make 8 identical flower arrangements. How many lilies would the florist use to create 6 identical arrangements.

Answers

Answer

Find out the how many lilies would the florist use to create 6 identical arrangements.

To prove

As given

A florist uses 200 lilies to make 8 identical flower arrangements.

$florist\ uses\ lilies\ to\ make\ 1\ identical\ flower\ arrangements = (Total\ number\ of\ lilies)/(Total\ numbers\ of\ flower\ arrangement)$

$florist\ uses\ lilies\ to\ make\ 1\ identical\ flower\ arrangements = (200)/(8)$

Florist uses lilies to make 1 identical flower arrangements = 25

Now calculate lilies for the 6 identical arrangements.

lilies would the florist use to create 6 identical arrangements = 25 × 6

= 150

Therefore the number of liles uses for 6 identical flower arrangements are 150.

Final answer:

To create 6 identical flower arrangements, the florist would use 150 lilies.

Explanation:

To solve this problem, we can use a ratio. The florist uses 200 lilies to make 8 identical flower arrangements, so the ratio is 200 lilies : 8 arrangements. To find out how many lilies would be used to create 6 identical arrangements, we can set up a proportion and cross multiply:

200 lilies / 8 arrangements = x lilies / 6 arrangements. Cross multiplying gives us 200 * 6 = 8x, which simplifies to 1200 = 8x. Dividing both sides by 8 gives us x = 150. Therefore, the florist would use 150 lilies to create 6 identical arrangements.
