Answer:
y = -5/9x + 4.1
(try doing this yourself first with different points to make sure this is the right answer, because im to lazy to check myself but ill try checking D:)
Step-by-step explanation:
first you have to find the slope . to do this use the equation y2 - y1/ x2 - x1
so write as -2 - 3/ -7 - 2 is equal to -5/-9
so now write y = -5/9x + b
we must now find the y-intercept so substitute one of the points given. lets substitute 2,3 it looks easier. So it will look like 3 = -5/9(2) + b
3 = -5/9(2) + b
3 = -10/9 + b
b = 3 + 10/9
b = 4.111111
um just round to the tenth place

- Slope Formula:
Step-by-step explanation:
<u>Step 1: Define</u>
<em>Choose any 2 points from the chart.</em>
Point (-6, 11)
Point (-2, 1)
<u>Step 2: Find slope </u><em><u>m</u></em>
- Substitute:

- Simplify:
8.5b.
7a= 5a +3b
-5a -5a
2a = 3b
/2
a= 1.5b
Solve by substitution and you get;
8.5b=8.5b
Because of the lack of constants in the equation there isn't a definite answer.
Answer:
1. y is dependent
x is independent
2. y=64x+0
4. 64*5=320
5. 128= d(2)
d =128/2
d=64 miles per hour
6. 6.25
400/64 = 25/4
25/4 = 24/4+1/4
6.25 hours

Answer:
81.6 inches squared
Step-by-step explanation:
The formula for calculating all parallelograms is Area+=base*height.
The height is given to you, 6.8, the base of the figure is also given, 12.
Now all you have to do is to multiply.
That would get you to 81.6.
(When asked for area of parallelogram, the length of any line other than the height and base is not needed)
hoped this helped!
