Answer 1

Answer:

f(x)=2x−5 if x≤−3

Since the value of x is -3, the first function will be the correct option.

Step-by-step explanation:

The given function is -

f(x)=2x−5 if x≤−3

f(x)=−3x+4 if x>−3

Now we have to evaluate f(-3).

Since we have to calculate the value of f at x = -3, we have to choose the first function.

That is f(x) = 2x - 5.

Hence,

f(−3)=2∗(−3)−5=−6−5=−11

Therefore we have the value

f(−3)=−11

Since the domain of the function is divided into two parts, we have to choose any one function for a given value of x,

For values of x less than or equal to -3, we will use the first function. That is,

f(x)=2x−5 for all x∈(−∞,−3]

And for values of x greater than -3, we will use the second function. That means,

f(x)=−3x+4 for all x∈(−3,∞)

HELP Solve for w x and y

Answers

Step-by-step explanation:

take ∆PRT

angle prt = 30°(||sides, traversal, opp angles)

angle ptr = 45+y(|| sides, opp angles)

x+30+45+y = 180

x+y = 180-75= 105

x= 105-y

take triangle zrt

angle zrt =30(parallel sides and traversal with opp angles)

angle ztr = y(parallel lines)

30+y+w = 180

w = 150-y

angle pzt+azr = 360-300+2y=60+2y

pzt= 30+y

Two poles meet at the top of the teepee. The angle at which they meet is equal to twice the complement of the angles that the poles form with the ground. What is the measure of the angle at which the two poles meet at the top of the teepee

Answers

The measure of the angle at which the poles meet at the top of the tepee is 180 degrees

Complementary angles

Complementary angles are angles which sum is equals to 90 degrees. Two angles complement each other when there sum is 90 degrees.

The two poles meet at the top of the tepee.

The angle at which they meet is equals to twice the complement of the angles that the poles form with the ground. Therefore,

Complement of the angles that the poles form on the ground = 90°

Then the measure of the angle at which the poles meet at the top of the tepee is as follows:

2(90) = 180°

Therefore, the measure of the angle at which the poles meet at the top of the tepee is 180 degrees

Last Saturday, Ben and Dominic set up a lemonade stand to help their grandmother use
the lemons from her trees. They used 2 lemons for each cup of lemonade. By the end of the
day, the boys had sold 21 pitchers of lemonade. If each pitcher held 9 cups, how many
lemons did Ben and Dominic use?

Answers

Answer:

378 Lemons

Step-by-step explanation:

Because you use 2 lemons for every cup, you first need to find how many lemons per pitcher by multiplying 9 by 2 to get 18, so 18 lemons per pitcher, then multiply that by 21 because that's the total amount of pitchers to get 378 lemons

[tex]6 \times 27 \times 28 \times 23 \times 3 = 312984[/tex]

Answer:

312984

Step-by-step explanation:

To solve the equation 6 x 27 x 28 x 23 x 3, you can follow these steps:

Start by multiplying the first two numbers: 6 x 27 = 162.

Then multiply the result by the next number: 162 x 28 = 4536.

Continue multiplying by the next number: 4536 x 23 = 104328.

Finally, multiply by the last number: 104328 x 3 = 312984.

The final result is 312984

Solve the system
of equation by
using subsitution,
Y=2x +3
x - y = -2

Answers

Answer:

The solution to this system of equations is (-1, 1).

Step-by-step explanation:

A system of equations is a "a finite set of equations for which common solutions are sought". Or, they are a pair (or more) of equations that either intersect, are parallel, or the same line. For the sake of simplicity, we are going to focus on systems of equations that intersect and only have one solution.

A solution to a system of equations that intersect is represented by a point (x, y). This makes sense because at the intersection of two points, there lies a point.

So how do we find this point? We do this by solving the system of equations. We show that there exists a point in which two lines can be satisfied simultaneously. But how can we do that? Trial and error?! Well, no. There are some ways of approaching this.

The first method is graphing. By either using an external source or doing it yourself, graphing two lines and showing where they intersect is one of the more understandable ways of solving a system of equations. The point where they cross is the solution of the system.

The second method is elimination. This is observing that a system of equations can be combined together to eliminate a variable (x or y) and solving for the other in a one-variable equation. For example, say that I have this system of equations:

x - y = 1

x + y = 1

By simply adding the two together, I get:

2x = 2

x = 1.

Since we already have x = 1, we can substitute it back into one of the original equations to get y.

1 + y = 1

y = 0.

So, the solution to this system of equations would be (1, 0). Speaking of substituting ...

The third method is substitution. This is observing that a variable (x or y) can be written in terms of the other and then using that to substitute in and make one of the equations one-variable.

y = 2x + 3

x - y = -2

We can see that y is already in terms of x in the first equation, so let's substitute y for 2x + 3 in the second equation.

x - (2x + 3) = -2

- x - 3 = -2

- x = 1

x = -1

We can substitute x back into one of the original equations.

y = 2(-1) + 3

y = -2 + 3

y = 1

Therefore, the solution to this system of equations is (-1, 1).

a 65 foot ladder is leaning against a well. Its lower end is 25 feet away from the wall. How much farther away will it be if upper end is moved down 8 feet?

Answers

Answer:  14 feet

=====================================================

Explanation:

Check out the diagrams below.

We'll start with the left diagram (marked "before") which is a right triangle with the horizontal leg of 25 feet and hypotenuse 65 feet.

Use the pythagorean theorem to find the vertical side x.

a^2 + b^2 = c^2

25^2 + x^2 = 65^2

625 + x^2 = 4225

x^2 = 4225 - 625

x^2 = 3600

x = sqrt(3600)

x = 60

The top of the ladder is 60 feet high when placed against the wall in this configuration.

------------------

If the upper end is moved down 8 feet, then x-8 = 60-8 = 52 feet is the new height of the ladder. Refer to the "after" in the diagram below.

Like earlier, we'll use the pythagorean theorem to find the missing side.

a^2 + b^2 = c^2

y^2 + 52^2 = 65^2

y^2 + 2704 = 4225

y^2 = 4225 - 2704

y^2 = 1521

y = sqrt(1521)

y = 39

The horizontal distance from the ladder base to the wall is now 39 feet.

Earlier it was 25 feet, so it has increased by 39-25 = 14 feet.
