Taya2010 [7]

Answer:

2x + 3

Step-by-step explanation:

(10x² + 19x + 6) ÷ (5x + 2)​ =

= (10x² + 15x + 4x + 6) ÷ (5x + 2)​

= [5x(2x + 3) + 2(2x + 3)] ÷ (5x + 2)​

= [(5x + 2)(2x + 3)] ÷ (5x + 2)​

= 2x + 3

Two-fifths of one less than a number is less than three-fifths of one more than that number. What numbers are in the solution se
Soloha48 [4]
Let us say, the number is "a"

one less than "a" is ... well a - 1
2/5 of that will be... well, 2/5 * ( a - 1)

one more than "a" is... well a + 1
3/5 of that is.. hmmm 3/5 * (a + 1)

now, we're told that, the first expression is "less than" the second one, thus

\bf \cfrac{2}{5}(a-1)\ \textless \ \cfrac{3}{5}(a+1)

solve for "a", or make it "x" if you wish, same thing anyway

What is the y-coordinate of point D after a translation of (x, y) ? (x + 6, y – 4)?
Mandarinka [93]

Answer:

Y-coordinate = y - 4

Step-by-step explanation:

In the given question point D coordinate is (x, y)

and D after translation

x goes to 6 unit to the right and y goes to 4 unit down.

Hence,

          Y-coordinate = y-4

Example:From graph

              Let point D coordinate (x , y) = (2 , 3)

After rotation

              D coordinates is (x+6 , y-4) = (2+6 , 3_4) = (8 , -1)

Helen plays basketball. For free throws, she makes the shot 78% of the time. Helen must now attempt two free throws. C = the eve
riadik2000 [5.3K]

Answer:

0.6708 or 67.08%

Step-by-step explanation:

Helen can only make both free throws if she makes the first. The probability that she makes the first free throw is P(C) = 0.78, now given that she has already made the first one, the probability that she makes the second is P(D|C) = 0.86. Therefore, the probability of Helen making both free throws is:

P(C+D) =  P(C) *P(D|C) = 0.78*0.86\\P(C+D) = 0.6708

There is a 0.6708 probability that Helen makes both free throws.
