How do you graph y=1x+3

Answers

Answer 1
Answer: Start on (0,3) since the y-intercept is 3. Move 1 unit up, 1 unit to the right. Then 1 unit down, one unit left....
Answer 2
Answer: When you are graphing, you need to remember that mx is the slope, and b is the y intercept. Since the y intercept is 3, you place your first point at (0,3). Now since the slop is positive one, you will go right 1, up one and place a point, and then right 1, up one and place a point and so on. You can also extend the line farther down by going left 1, down 1, etc.

If a function f is continuous for all x and if f has a relative maximum at (-1, 4) and a relative minimum at (3, -2), which of the following statements must be true? (a) The graph of f has a point of inflection somewhere between x = -1 and x= 3 (b) f'(-1) = 0 (c) this is wrong (d) The graph of f has a horizontal tangent line at x = 3 (e) The graph of f intersects both axes - Correct answer I understand why e is correct, but I do not get why a, b, and d are all wrong.

A baseball player won 80% of the games he pitched. if he pitched 35 ballgames, how many games did he win?

A supermarket has found that 60% of their customers spend more than $75 each visit. Whats the probability that the next 2 customers will each spend more than $75? ×

Answers

Answer: 0.36 or 36%
60%=60/100=0.6

60% is the same as saying 60/100 or 0.6

To solve for the probability of this problem, we have to, multiply the odds of the two separate events together

event1 is a customer that spends more than 75$. The odds of that happening are .6

event 2 is a customer that spends more than 75$. The odds of that happening are .6

probability=event1*event2
probability=.6*.6 
probability=.36 or 36%

Distributive property to express 16+48

Answers

So,

I will un-distribute the GCF of the two numbers.

16(1 + 3)

Distributing we get:
16(1) + 16(3)
16 + 48

After applying the distributive property the expression (16 + 48) is written as,

⇒ 16 (1 + 3)

We have to give that,

A mathematical expression is,

⇒ 16 + 48

Now, apply the distributive property to express the expression as,

⇒ 16 + 48

Since, GCD of (16, 48) = 16

Hence, take 16 as the common number,

⇒ 16 + 48

⇒ (16 × 1) + (16 × 3)

⇒ 16 (1 + 3)

So, it can be written as,

⇒ 16 (1 + 3)

The cost of 2 tv and 3 DVD player is $1421. The cost of 1 dvd is half of the tv. What's the cost of the tv

Answers

The cost of one tv is double than cost of one DVD;

The cost of 2 tv is 4 times more cost one DVD ;

The cost of 2 tv and 3 DVD player is 7 times more cost one DVD ;Then, 1 DVD cost 1421 ÷7 = 201 $ ;
1 tv cost = 2 * 201 = 402 $ ;

Final answer:

To solve the problem, you set up two equations based on the information given. Then, you substitute one equation into the other to solve for the cost of the TV, which comes out to be approximately $405.43.

Explanation:

To answer this question, you need to use algebra. We can create two equations based on the information given. Let's say the cost of a TV is x and the cost of a DVD player is y. According to the problem, we have two equations:

  • 2x + 3y = $1421 (This comes from the total cost of the 2 TVs and 3 DVD players)
  • y = 0.5x (This comes from the fact that the cost of a DVD player is half the cost of a TV)

We can then substitute the second equation into the first to get:

  • 2x + 3(0.5x) = $1421
  • 2x + 1.5x = $1421
  • 3.5x = $1421

To find the cost of the TV 'x', you can divide both sides of the last equation by 3.5 resulting in x = $405.43. So the cost of one TV is approximately $405.43.
