Answer:

(2, 4)

Step-by-step explanation:

Given the system of equations

y=3×-2.... 1

y-2=×​ ... 2

Substitute 2 into 1

y = 3(y-2) - 2

y = 3y - 6 - 2

y - 3y =-6-2

-2y = -8

y = -8/-2

y = 4

Recall that

x = y - 2

x = 4-2

x = 2

Hence the solution (x, y) is (2,4)

Answer:

B

Step-by-step explanation:

Answer:

(-1,-2)

Step-by-step explanation:

Think of the line y=x as a mirror.  The image of the point (1,2) is obtained by drawing a line through (1,2) perpendicular to the line y=x and finding the point on the perpendicular line that is equal distance from the line y=x but on the other side. This gets you to the point (2,1).

Similarly, from (2,1) find the mirror image using the line y=-x as the mirror. You travel diagonally 1.5 diagonal squares to reach y=-x and then continue another 1.5 diagonals to reach (-1,-2) which is your answer.

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

Explanation:

With many trig problems, a diagram should help steer you in the right direction. See below.

The red angle is the angle of depression. It's formed by starting off looking straight horizontal, then we look down 26 degrees. The blue angle adds to the red angle to get 90, so we can see that 26+64 = 90. Or you could say 90-26 = 64.

The goal is to find the value of x, which is the length from B (the lighthouse base) to point C (the ship's location).

The lighthouse is 250 ft tall, meaning AB = 250

We'll use angle BAC, or angle A for short, as the reference angle. This is the blue angle in the diagram.

We have a known adjacent side (AB = 250) and an unknown opposite side (BC = x). We use a tangent ratio to tie these sides together with the reference angle in question. This way we can solve for x.

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

tan(angle) = opposite/adjacent

tan(A) = BC/AB

tan(64) = x/250

250*tan(64) = x

x = 250*tan(64)

x = 512.575960394824

x = 513

The distance from B to C is roughly 513 feet.

I'm rounding to the nearest whole number because the other values given to you are whole numbers.

Answer:

48

Step-by-step explanation:

Answer:

B

Step-by-step explanation:

We assume the function goes infinitely both "left" and "right" so the domain is (-inf, inf).

We can also see that it has a maximum in (0, 10), so it takes all the values from -inf to 10 exactly. If it never reached 10, it'd be (-inf, 10) but it does, so it's (-inf, 10].

Answer:

5(n+1)/((n+1)(n+3))

5/(n+3) is a answer

Step-by-step explanation:

(n+1)/(n+1)=1

The solution is, the simplified product of the expression 5/n+1*n+1/n+3 is 5/(n+3) .

here, we have,

given that,

the expression is  5/n+1*n+1/n+3

now, we have to find the  simplified product.

as, * means the multiplication,

we get,

5/n+1*n+1/n+3

=5*(n+1)/((n+1)*(n+3))

now, we know that,

(n+1)/(n+1)=1

so, we get,

5*(n+1)/((n+1)*(n+3))

=5*1 /(n+3) *1

=5/(n+3) is a answer

Step-by-step explanation:

The preceding two stages are development stage and startup stage. In growth stage one should first focus on fine tuning the business model and by finding ways for operational inefficiencies. Dale has actually already identified the inefficiency which is new machines and non being able to cater to some customers due to lack of machines. In this exact stage businessman try to grow the business by analyzing the main profit drivers and the finding ways to grow the profit driver with less cost

Answer:

Horizontal Asymptote → y = 17

Step-by-step explanation:

Given function is f(x) = [tex]\frac{2}{5}(16)^{x+13}+17[/tex]

Here, the parent function is g(x) = [tex]\frac{2}{5}(16)^x[/tex]

Parent function has a horizontal asymptote as y = 0

If the function g(x) is shifted 13 units left and 17 units up, new function will be f(x) = [tex]\frac{2}{5}(16)^{x+13}+17[/tex]

When the parent function is shifted 17 units up, horizontal asymptote shifts 17 units upwards.

Therefore, horizontal asymptote of the image function becomes y = 17.

Answer:

(B)

b + t = 15

2b + 3t = 45

Step-by-step explanation:

Bicycles and tricycles are represented by the letters b and t respectively.

total no of bicycles and tricycles = 15

So,

b + t = 15

Each bicycle has 2 wheels and each tricycle has three wheels.

So,

No of wheels in b bicycles = 2b

No of wheels in t tricycles = 3t

Total no of wheels = 45

So,

2b + 3t = 45

Answer:

x= -6

y= -5

Step-by-step explanation:

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

Answer:

(-6,-5)

x=-6

y=-5

Step-by-step explanation:

9x-7y=-19

5x-3y=-15

When solving with elimination, you multiply both equations by a number to get two terms to cancel each other out.

We can try to get the y's to cancel out. The LCD of 7 and 3 is 21, so we multiply one equation by 3 and another by -7 (to get one -21y and one 21y)

{9x-7y=-19}*3=

27x-21y=-57

{5x-3y=-15}*(-7)=

-35x+21y=105

Now, we combine the two equations.

27x-21y=-57

-35x+21y=105

-8x=48

Now, solve for x.

-8x=48

x=-6

Now we can plug x into one of the original equations to get y.

I will use 9x-7y=-19.

9(-6)-7y=-19

-54-7y=-19

Add 54 to both sides.

-7y=35

y=-5

We can put these values into an ordered pair: (-6,-5).

Answer:

6

Step-by-step explanation:

So you want to round both denomaters to what they can mutiply to so it will be 6 so the 4 1/2 will be 4 3/6 and the 2 2/3 will be 2 4/6. Then you multiply to get 6

Answer:

2 * 10^-3 oz

Step-by-step explanation:

Given that:

Number of staples per box = 6 * 10^3

Weight of staple box = 12 oz

Weight per staple = (weight of staple box / number of staples per box)

Weight per staple = 12 / 6 * 10^3

Weight per staple = 12 / 6 * 1000

= 12 / 6000

= 0.002 oz

= 2 * 10^-3 oz
