Answer:


Step-by-step explanation:

<u>How do you find the equation of a line parallel to another line? </u>

<em>Method 1:</em> Using Slope Intercept Form

Substitute the slope from original line (3 in this case) into the equation of the line y = 3x + b.

Substitute the given point (1,7) into the x and y values 7 = 3(1) + b.

Solve for b (the y-intercept)

Substitute this value for 'b' in the slope intercept form equation y = 3x + 4.

<u>How do you find the Y intercept of a parallel line? </u>

Step 1: Find the slope of the line. To find the slope of the given line we need to get the line into slope-intercept form (y = mx + b), which means we need to solve for y: The slope of the line 3x – 5y = 9 is m = 3/5. Therefore, the slope of the line parallel to this line would have to be m = 3/5.

The temperature outside is currently 10°F. It will fall at a constant rate of 3°F per hour. Which temperature will it be in 4 ho
Triss [41]

Answer:

T4 = -2°F

Step-by-step explanation:

Given the following data;

Current temperature = 10°F

Constant, K = 3°F

Time, t = 4 hours

In four (4) hours, we have;

T = kt

Substituting into the equation, we have;

T = 3 * 4

T = 12°F

T4 = current temp - new temp

T4 = 10°F - 12°F

T4 = -2°F

Therefore, the temperature it will be in 4 hours is - 2°F.

Could someone maybe explain to me what I need to do here? Please? I would love you forever! Lol, I need help.....
Maurinko [17]

Answer:

If you cut along the dotted line and remove the pieces you cut off, fold the sides inward and you get a moving box.

Each dotted line is 2 feet long, and each un-dotted line is also two feet.

Good luck, I hope this helps because honestly I just tried to figure it out for an hour. Lol.

Factor completely, then place the answer in the proper location on the grid.<br><br> a^6 - 25b^2
Solnce55 [7]
This is the difference of 2 squares 

square root of a^6  = a^3
and square root of 25 b^2  = 5b  so we get 

(a^3 + 5b)(a^3 - 5b)

Thats the answer
