Answer:
y = -13x - 1
General Formulas and Concepts:
<u>Algebra I</u>
Slope-Intercept Form: y = mx + b
- m - slope
- b - y-intercept
Step-by-step explanation:
<u>Step 1: Define</u>
<em>Identify variables</em>
Slope <em>m</em> = -13
y-intercept <em>b</em> = -1
<u>Step 2: Find Equation</u>
- Substitute in variables [Slope-Intercept Form]: y = -13x + -1
- Simplify: y = -13x - 1
Answer:
the width is 9 23/30 feet ≈ 9.767 ft
Step-by-step explanation:
Let w represent the width of the train car. Then 6 times the width is 6w, and 8 ft less than that is (6w-8). We are told this amount is 50.6 feet, so we have ...
6w -8 = 50.6
6w = 58.6 . . . . . . . add 8; next divide by 6
58.6/6 = w = 586/60 = 293/30 = 9 23/30 . . . . feet
This is a repeating decimal: 9.766666...
The width of the train car is 9 23/30 ft, about 9.77 ft.
Answer:
y = 0.9x - 0.8
Step-by-step explanation:
First you use the formula m = (y2-y1) / (x2-x1)
Sub in the 2 points you are given and you get m = (-8-1) / (-8-2)
m = -9/-10 = 9/10
Now u use the point slope formula, (y - y1) = m(x - x1)
Sub in the points and you get (y - 1) = 9/10 (x-2)
Expand it out to get y - 1 = 9/10x - 18/10
multiple everything by 10 = 10y - 10 = 9x -18
make y the subject, 10y = 9x - 8
y = 0.9x - 0.8
(-3)^2 -4(-3) + 3
9 + 12 + 3
So the answer is 24
Answer:
The answer is 463 inch cubed
Step-by-step explanation:
you do 8 x 8 x 7 which will give you 448 volume for just the cube.
then you do 5 x 3 x 1 = 15
you add 448 with 15 you will get 463
