Answer:

OPTION C: 2x - y = -1

Step-by-step explanation:

Equations of two straight lines do not have a solution when they do not meet. Also, two parallel lines never meet.

Given the equation of the first line is: 2x - y = 1. So, the line parallel to this line should be the answer.

Note that the equations of two parallel lines only differ by a constant.

i.e, If ax + by + c = 0 is an equation of a line then the equation of the line parallel to this would be ax + by + k = 0.

Hence, the required answer is: 2x + y = -1, which is OPTION C.

While visiting Wallawulla State​ Park, Joe approximated the angle of elevation to the top of a mound to be 40 degrees . After wa
katen-ka-za [31]

Answer:

Height of mound = 794 ft

Step-by-step explanation:

To illustrate the angle of elevation and distance, i have drawn it and attached below.

Now, from my diagram;

h = the height of the mound

At his first point of his trip to the foot of the mound, the angle of elevation is 40°, while the horizontal distance to the foot of the mound is "X"

So, by triangle definition,

tan(40°) = h/x

And so;

h = x tan40

h = 0.8391x  - - - - (eq 1)

At his second point of the trip to the foot of the mound, Joe is now,

"(x - 450) ft" from the foot of the mound.

Thus, his angle of elevation is 40 + 18 = 58°.

So, by triangle definition,

tan(58°) = h/(x - 450)

h = (x - 450)•(tan(58°))

h = 1.6003(x - 450)

h = 1.6003x - 720.135   - - - - -(eq2)

To get the height(h) of the mound, let's equate (eq1) to (eq2).

0.8391x = 1.6003x - 720.135

1.6003x - 0.8391x = 720.135

0.7612x = 720.135

x = 720.135/0.7612

x = 946.0523 ft

Let's put this value for x in eq (1);

h = 0.8391 x 946.0523 = 793.83 ft ≈ 794ft

Answer:

<h3>b=\frac{t-5}{4}</h3>

Step-by-step explanation:

4b+5=t

First, you must get the variable alone! Substract 5 from both sides!

4b<u>+5=t </u>

    -5  -5

The 5 cancels out because 5-5=0

The new equation is 4b=t-5

You must divide by 4 to get the variable alone since your solving for b!

<u>4b=t-5</u>

4      4

b= \frac{t-5}{4} \\

This is your answer!

A wall is 300 square feet.a gallon of paint covers 110 square feet. What is an appropriate conversion factor to help determine h
saveliy_v [14]

Answer:

(1 gallon)/(100 ft^2)

Step-by-step explanation:

(1 gallon)/(100 ft^2) is a good conversion factor.  We could also use (100 ft^2)/(1 gallon), but I like the first, since the calculation is simpler:

(300ft^2)*/(1 gallon)/(100 ft^2) = 3 gallons  [I like multiplication better than division, and especially here, since 300/100 is 3, if my memory is correct.
