What is the slope of the line 3 + 4x = 2y - 9

Hello! 

Ok so ideally we would like to see this in y=mx+b form. But it will take some algebreic skills to ninja our way through this. 

I'll show my steps so you can follow, 

3+4x = 2y - 9 (original equation) 

Next we just add 9 to both sides, 

12 + 4x = 2y, now we can divide both sides by 2,

y=2x+6 as our final equation. This is in y=mx+b form, thus the slope of our line is 2 because the 2 is sitting in the m space of the equation. If you  still dont understand linear stuff, I'd google slope-intercept form 

Hope this helped!

You need to make both numbers the same denominator (bottom number). Do this by multiplying. So for the first question you need 15 as the denominator. 3x3=9 5x3=15 first one is 9/15. Then its 1x5=5 and 3x5=15. Then you add 9+5 to get 14. The denominator stays the same. 14/15. This cannot be reduced. If reduced, you would be able to divide both numbers by the same number.
1. 14/15
2. 5/6
3. 1/2
4. 13/24
5. 13/24
6. 9/10
7. 5/9
8. 11/35
9. 5/8
10. 1/2

The height h, in feet, of a ball that is released 4 feet above the ground with an initial velocity of 80 feet per second is a fu
gulaghasi [49]

Answer with Step-by-step explanation:

The height of the ball from the ground as a function of time is given by

h(t)=-16t^2+80t+4

The height of the ball at any instant of time can be found by putting the value of time 't' in the above relation as

Part a)

Height of ball after 2 seconds it is released is

h(2)=-16\times 2^2+80\times 2+4=100feet

Part b)

Height of ball after 4 seconds it is released is

h(4)=-16\times 4^2+80\times 4+4=68feet

What is 25quarter and 3 nickels and 1pennie represent in decimal form and fraction form?
Vilka [71]
4 quarters is a dollar. So 25 divided by 4 is $6.25. A nickel is 5 cents, so multiply 3 by 5. Giving us $.15. And finally the one penny adds $.01. Add it all together and you get $6.41 for the decimal. Now for the fraction, since 100 cents is $1, the denominator is 100. And since there are $6, it would be 6_41/100 for the fraction.

scoray [572]
The area of the resulting two-dimensional cross section with the dimensions shown in the figure can be determined by simply using the formula for the area of a rectangle.

Given:

Length = 12 mm
Width = 7 mm

Area = L x W
Area = 12 mm x 7 mm
Area = 84 mm^2
