The possible values of x are given by x−3≥2 . What is the least possible value of 5x ?
mamaluj [8]
The answer would be twenty five because x-3 \geq 2
 equals x  \geq 5 leaving you with x = 5 at a minimum. So 5x: 5 x 5 = 25

Hope this helps! :)

what is the quotient (65y3 15y2 − 25y) ÷ 5y? a. 13y2 3y − 5 b. 13y3 3y2 − 5y c. 13y2 − 3y 5 d.13y2 − 3y − 5
Aneli [31]

Keywords:

<em>Division, quotient, polynomial, monomial </em>

For this case we must solve a division between a polynomial and a monomial and indicate which is the quotient.

By definition, if we have a division of the form: \frac {a} {b} = c, the quotient is given by "c".

We have the following polynomial:

65y ^ 3 + 15y ^ 2 - 25y that must be divided between monomy5y, then:

C (y) represents the quotient of the division:

C (y) = \frac {65y ^ 3 + 15y ^ 2 - 25y} {5y}

C (y) = \frac {65y ^ 3} {5y} + \frac {15y ^ 2} {5y} - \frac {25y} {5y}

C (y) = 13y ^ 2 + 3y-5

Thus, the quotient of the division between the polynomial and the monomial is given by:

C (y) = 13y ^ 2 + 3y-5

Answer:

The quotient is: C (y) = 13y ^ 2 + 3y-5

Option: A

Emma is playing miniature golf. Her ball is 2 feet to the left of the right-hand wall. The hole is 4 feet to the left of the wal
NISA [10]

Answer:

<u></u>

  • <u>She should aim 6 feet down the wall</u>

Explanation:

The diagram attached sketches the situtation.

Since the angle with which the ball hits the wall is the same with which it bounces, angle β is the same for the two shown triangles.

Then, since both are right triangles, then all the angles are congruent and the triangles are similar. Hence, you can equal the ratios of the sides, to make an equation:

  • x/4 = y/2 ⇒ x = 2y

You have other equation:

  • x+ y = 18

Substitute

  • 2y + y = 18
  • 3y = 18
  • y = 18/3
  • y = 6 ← this is the distance down the wall where the ball should hit

  • x = 2(6) = 12

Then, she should aim 6 feet down the wall.

What is the value of y in the equation 2 + y = −3?<br> -1<br> -5<br> 1<br> 5
Thepotemich [5.8K]
To do this subtract 2 from each side of the equation to get y = -5, so the value of y in this is -5. Hope this helps!
