Solve y=f(x) for x. Then find the input when the output is −3. f(x)=−7x−2 x= The input is when the output is −3.

Answers

Answer 1

Answer:

The input is 1/7

Step-by-step explanation:

If y =f(x)

Given that f(x) = -7x -2, then y = -7x-2

x is the input

y is the output

Given the output y = -3, we are to find the input value x

Recall that y = -7x-2

On substituting the value of y into the equation

-3 = -7x - 2

-7x = -3+2

-7x = -1

x = -1/-7

x = 1/7

Hence the input is 1/7

Answer:

The expected value is $4.35

Step-by-step explanation:

Here, we want to find the expected value

To

do that, we simply will multiply each of the payouts by the individual probabilities, then add the results

Mathematically, we have this as;

0.35(1) + 0.2(2) + 0.1(5) + 8(0.2) + 10(0.15)

= 0.35 + 0.4 + 0.15 + 1.6 + 1.5 = $4.35

The americans with disabilities act sets a maximium angle for a wheelchair ramp entering a business at 4.76 degrees. Determine the horizontal distance needed to occomidate a ramp that goes up to a door.

Given that,

The maximum angle for a wheelchair ramp entering a business at 4.76 degrees.

We need to find the horizontal distance needed to accomidate a ramp that goes up to a door 4 feet of the ground.

We can solve it using trigonometry.

[tex]\tan\theta=\dfrac{h}{d}[/tex]

Where

h is height

d is the angle of elevation

[tex]d=\dfrac{h}{\tan\theta}\\\\d=\dfrac{4}{\tan(4.76)}\\\\d=48.03\ ft[/tex]

So, the horizontal distance is equal to 48.03 feet.

solve each system by substitution
1/2x+1/3y=6
x-y==2

Answers

Step-by-step explanation:

First, let's rewrite the equations.

1/2x + 1/3y =6

x - y = 2

The easiest system to use for substitution is the second one.  Let's solve for X.

x - y = 2

    add y to both sides!

x = 2 + y

Now that we know x = 2 + y we can use it to substitute in the first equation.

1/2(2 + y) +1/3y = 6

1 + 1/2y +1/3y = 6

5/6y = 5

y = 36/5

If x = 2, y = 3 and z = 5, calculate the following: 5x - z

I'm not 100% sure, but I think the answer is 10 units squared.

Step-by-step explanation:

Find the area of each triangle, by multiplying each side, and dividing the answer in half. Add both of the triangles together, ending up as 6. Now we just find the area of the square. 2x2=4, add that to both of the triangles, and we're done. (2x2) ÷ 2 = 2 | (2x4) ÷ 2 = 4 | 2x2 = 4 | 4+4+2=10

Answer:

area=10 units^2

Step-by-step explanation:

[tex]a=\frac{(2+2+4)+(2)}{2} *2\\ =\frac{8+2}{2} *2\\ =\frac{10}{2} *2\\ =5*2\\ =10[/tex]

You have two decks of cards and you select a card from each deck. What is the probability to selecting a jack both times?

Answers

Answer:

The probability is 1/13 (1 to 13).

Step-by-step explanation:

In a card deck, there are 52 cards with 4 Jacks. If you simplified this probability, the answer would be 1 to 13.

4/52 = 1/13

In two card decks, there are 104 cards with 8 jacks.  If you simplified this probability, the answer would also be 1 to 13.

8/104 = 1/13
