Austin took 300 baseball cards from his collection. He gave 60% of them to his brother. How many baseball cards did Austin give to his brother?

Answer:

x=4 y=8

Step-by-step explanation:

Answer:

f(x)= -2x²- 4x + 5 when x= - 3

f(-3)= -2(-3)²- 4(-3) + 5

f(-3)= -2(9)+12+5

f(-3)= -18+12+5

f(-3)= -18+17

f(-3)= -1

Answer:

[tex]30 = 10 + 4x[/tex]

Answer:

Janice rented the bike for 5 hours.

Step-by-step explanation:

The equation used to model this problem is 10 + 4x = 30. Subtract 10 from both sides. You are now left with 4x = 20. Divide both sides by 4. Now you have x = 5. This answer results in the conclusion that Janice spent 5 hours with the bike.

Answer:

2 x^3+ 8 x^ 2 + 3 x + 12

Step-by-step explanation:

Answer:

2x³ + 8x² + 3x + 12

Step-by-step explanation:

Given

(2x² + 3)(x + 4)

Each term in the second factor is multiplied by each term in the first factor, that is

2x²(x + 4) + 3(x + 4) ← distribute parenthesis

= 2x³ + 8x² + 3x + 12

Answer:

  (x, y) = (-1, 5/2)

Step-by-step explanation:

The only variable with a coefficient that has a magnitude of 1 is x in the first equation. Using that equation, we can write an expression for x:

  x = 2y -6

This can be substituted for x in the second equation.

  (7/2)(2y -6) +7y = 14

  7y -21 +7y = 14 . . . . . . eliminate parentheses

  14y = 35 . . . . . . . . . . . add 21

  y = 35/14 = 5/2 . . . . . divide by the coefficient of y

  x = 2(5/2) -6 = -1

The solution is (x, y) = (-1, 5/2).

X + 1 by x = 99 find the value of 100x by 2x square + 102x + 2

Answer:

The expression are equivalent

Step-by-step explanation:

The question requests that we show whether the equation -0.5( 1 -2h) is equivalent to 4(2h + 2) - 7h - 8.5 or not :

Simplifying 4(2h + 2) - 7h - 8.5 ; we have ;

4(2h + 2) - 7h - 8.5

8h + 8 - 7h - 8.5

8h - 7h + 8 - 8.5

h - 0.5

-0.5(1 - 2h)

-0.5 + h

= h - 0.5

Hence, both expressions are the same

Answer:

Not sure by the way the question is asked but I think the answer is x=(y-1)/4

Step-by-step explanation:

Subtract one from both sides: y-1=4x

Divide the four from both sides: (y-1)/4=x

Let x and y be the two numbers. Let's say that either x = y or x < y. To keep things relatively simple, we'll make both of these numbers positive.

We are told that they add to 50, so

x+y = 50

which solves to

y = 50-x

Their product is

x*y = x*(y) = x*(50-x) = 50x - x^2 = -x^2 + 50x

So the function

f(x) = -x^2 + 50x

will give us the product f(x) for the input x. Keep in mind that if we know what x is, then y = 50-x is used to find y.

The function f(x) graphs out a parabola that opens downward. Check out the diagram below. This means the very peak point of the parabola is what we're after. This is the vertex. At the vertex, we'll have f(x) maxed out as much as possible. This occurs at the point (25,625) meaning x = 25 and y = 50-x = 50-25 = 25 both multiply to x*y = 25*25 = 625, which is the largest possible product.

In short, this provides a visual means to confirm you have the correct answers for part b.

Answer: Water molecules are attracted to each other due to hydrogen bonding.

Step-by-step explanation: Water molecules bind to the other water molecules surrounding it. The hydrogen bonds holding the molecules together results in water’s relatively high surface tension.
