In order to save money for prom, Tom is going to walk his
neighbor's dog for $6 an hour and wash cars for $7.50 an
hour. His mother told him he is not allowed to work more
than 15 hours in order to keep up with his homework. If
Tom would like to make at least $75 to cover prom
expenses, help him determine combination of hours he can
work between the 2 jobs.
A. Write and graph a system of linear inequalities.
B. What are 2 possible solutions? (see choices below)
4 hrs dog walking & 8 hours car washing
3 hrs dog walking & 4 hours car washing
10 hrs dog walking & 3 hours car washing

Step-by-step explanation:

Answer:I understand that

Step-by-step explanation:

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:

y= -2x + 5. -2x is slope and 5 is y intercept.

Step-by-step explanation:

-2x is the slope 5 is y intercept. So what you do is add ten to both sides to get 2y= -4x +10. Then divide 2 by everything to get y alone. Now you have y=-2x + 5. this is now in proper y = mx + b form, where mx is slope. b is the y intercept, that's 5.

Answer:

-2x and then it's 5 for the y

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.

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:

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

In the problem and solution organization pattern, it is all about the ability to determine the problems affecting the organisation as well as proffer solutions on how to solve those problems. This would then lead to minimizing cost and maximizing profits. The example above which is about ideas on how to rescue endangered loggerhead turtle eggs is following same pattern.

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

Answer:

See explanations below

Step-by-step explanation:

Consider the line y=-2x+3.

The equation in point slope form is expressed as y-y0=m(x-x0)

m is the slope

(x0,y0) is the point

If the Line is parallel, slope m = -2

Substitute

y-6 = -2(x-5)

y-6 = -2x+10

y+2x = 10+6

y+2x = 16

Is the line is perpendicular

Slope m = -1/-2

m = 1/2

Substitute into the formula

y - 6 = -1/2(x-5)

2(y-6) = -(x-5)

2y-12 = -x+5

2y+x = 5+12

2y+x = 17

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.
