Answer:

x = -4, y =-8 is the solution to the system of equations.

Step-by-step explanation:

Given the system of equations as:

y= \dfrac{1}{2}x-6

and

x =-4

To find:

The solution to the system of equations = ?

Solution:

Here, we are given two equations and two variables i.e. x and y.

So, we can solve the system of equations for the values of x and y.

Let us first consider the 2nd equation.

x =-4 we already have the value of x.

Now, let us put the value of x in the 1st equation to find the value of y.

y= \dfrac{1}{2}x-6

\Rightarrow y= \dfrac{1}{2}\times (-4)-6\\\Rightarrow y= -\dfrac{1}{2}\times 4-6\\\Rightarrow y= -2-6\\\Rightarrow \bold{y =-8}

So,  the solution to the system of equations is:

x = -4, y =-8

the captain of a boat knows that the lighthouse on the coast is 200 feet tall. he measures the angle of elevation to the top of
krek1111 [17]

Answer:

The boat is 5727.25ft far from the coast

Step-by-step explanation:

Refer the figure given.

We need to find how far is the boat from the coast = AB

Angle of elevation = 2°

The lighthouse on the coast is 200 feet tall, AC = 200 ft

We have

           tan2=\frac{AC}{AB}=\frac{200}{AB}\\\\AB=\frac{200}{tan2}=5727.25ft

The boat is 5727.25ft far from the coast

F=1.8C+32 solve for given variable
liq [111]

Answer:

Step-by-step explanation:

The formula F = 1.8C + 32 can be used to find the temperature in degrees Fahrenheit F when the temperature is given in degrees Celsius C. For what value is the temperature in degrees Fahrenheit equal to the temperature in degrees Celsius? Justify your reasoning by writing and solving an equation. (Hint: If Fahrenheit and Celsius are equal, they can be assigned the same variable.)

Multiply and simplify
aleksandr82 [10.1K]

Answer and explanation:

1. 2 × 3/10 = 6/10 = 3/5

2. 8 × 4/8 = 32/8 = 4

3. 9 × 3/9 = 27/9 = 3

4. 12 × 2/11 = 24/11 = 2 2/11

5. 3 × 5/7 = 15/7 = 2 1/7

6. 2 × 3/5 = 6/5 = 1 1/5

7. 11 × 4/8 = 44/8 = 5 4/8 = 5 1/2

8. 10 × 1/4 = 10/4 = 2 2/4 = 2 1/2

9. 5 × 1/4 = 5/4 = 1 1/4

10. 11 × 2/7 = 22/7 = 3 1/7

Hope this helps!
