Y^2+5y  the greatest common factor is y so

y(y+5)

...

4x^2-49  this is a "difference of perfect squares" which always factors to:

(a^2-b^2)=(a-b)(a+b), in this case:

(2x-7)(2x+7)

...

5s^2-20  GCF is 5

5(s^2-4)  now the parenthetic term is a difference of squares so

5(s-2)(s+2)

I can't get the answer lol
Gelneren [198K]

Answer:

-7/4

Step-by-step explanation:

Recall that slope, m, is defined as the ratio rise to run:  rise/run.

Note that if we start at x = -2 (an arbitrary choice), and move 6 units to the right, we end up at x = 4.  This is the 'run.'  Simultaneously, y starts at 1 and decreases to - 6, a change of -7.  

Thus, the slope of the line through these two points is m = rise/run = -7/4

Please help me! Do any one of them, as long as the answer is correct!
quester [9]

Answer:

1.) 1-b, 2-a, 3-d, 4-c

Step-by-step explanation:

You recognize that the point-slope form of the equation for a line with slope m and point (h, k) is ...

... y - k = m(x - h)

____

Match this form to the given equations to determine (h, k). Once you determine (h, k) from the equation, find that point in the list of points to get your match-up. (All the slopes are correct, so you don't need to do any more work than just described.)

_____

For problems 3.) and 4.), use the above form with the given point and slope.

You plant flowers in your garden and only 75% of them sprout how many can you predict to sprout if you plant 20 seeds?
SSSSS [86.1K]
Well basically by reading this question, I believe that if 75% sprout of the 20 seeds your equation would look like this 20(0.75) 0.75 is basically a simplified version of the 75% just written as a decimal so basically your answer would be 15 seeds ( so I believe you will be able to predict that 15 seeds will sprout! Let me know if this was either, helpful or non- helpful! I hope you have done a wonderful job!
