Answer: 2:5

Step-by-step explanation: a simple memorization is to add the 2 parts of the ratio (5) and keep the original part (2) and thus you get 2:5

this is how my geometry teacher taught it.

Crazy boy [7]

Slope formula is y=mx+b. m is the slope and b is the y-intercept. You can plug the coordinates that are given, (-3,-3), to find the y-intercept.

y=-3/4x+b is the equation you have so far. Plug in (-3,-3):

-3=-3/4(-3)+b

Multiply -3/4*-3.

-3=9/4+b

Subtract 9/4 from both sides.

-21/4=b

Equation: y=-3/4x-21/4

-21/4 equals -5.25, so your y-intercept would be (0,-5.25). That is the first point that you can plot on your graph.

After this, to graph the rest of the equation, you need to use your slope, -3/4. Every point will be down 3, right 4 from the one before it. In this case, your next point to graph would be (4,-8.25). You can also find what the coordinates would be in the opposite direction by going up 3, and left 4 from the original y-intercept. In this case, the coordinates would be (-4, -2.25)

Graph the points: (0,-5.25), (4,-8.25), and (-4, -2.25). Connect all the points to form your line. Normally, graphing two or three points should be enough!

I hope this helps :)

stan cut two pieces of crown molding for his family room that were 8 feet 7 inches and 12 feet 11 inches. what was the total len

patriot [66]

Answer:

The total length of the molding is 21 feet and 6 inches

Step-by-step explanation:

* Lets explain how to solve the problem

- The length of the two pieces are 8 feet 7 inches and 12 feet 11 inches

- Each foot has 12 inches

- Lets change the lengths of the two pieces to inch

# First piece 8 feet 7 inches

∵ 1 foot = 12 inches

∴ 8 feet 7 inches = 8 × 12 + 7

∴ 8 feet 7 inches = 96 + 7

∴ 8 feet 7 inches = 103 inches

# Second piece 12 feet 11 inches

∵ 1 foot = 12 inches

∴ 8 feet 7 inches = 12 × 12 + 11

∴ 8 feet 7 inches = 144 + 11

∴ 8 feet 7 inches = 155 inches

- To find the total length add the two answers

∴ The total length of the molding = 103 + 155 = 258 inches

- Divide the answer by 12 to change it to feet

∵ 258 ÷ 12 = 21.5 feet

- To change it to feet and inch multiply 0.5 feet by 12

∵ 0.5 × 12 = 6 inches

∴ The total length of the molding is 21 feet and 6 inches

What is the slope of a line (1,4) and (5,24) ?

Sergeu [11.5K]

The slope formula is (y2 - y1)/(x2 - x1). It doesn't matter which one you use as x1 or x2 and long as you use the same order for the y's.

After plugging these 2 points in the formula, you get (24-4)/(5-1) = 20/4 = 5. Therefore, the slope is 5.
