Quadratic formula = (-b +- sqrt(b^2 - (4ac))) / 2a

\frac{ -12 +  \sqrt{(12)^2 -((4)(9)(-24))}}{2(9)}

and

\frac{ -12 - \sqrt{(12)^2 -((4)(9)(-24))}}{2(9)}

then simplify and solve

Y=0.5x how do you work it
photoshop1234 [79]
Plug any number in for x and find the resulting y, then if you need to graph place the coordinate points on the plane. For example if you set x=2 the equation becomes y=0.5(2). From here we can see 0.5(2)=1 and this is equal to 1 so in a data chart you would write under x the number 1 and under y the number 2.

Solve:<br> 3/4 (5 f - 3) = 3/8<br> F=?
VMariaS [17]

Answer:

f= 0.7

Step-by-step explanation:

Multiply by reciprocal on both sides: 4/3 * 3/4(5f-3) = 3/8 * 4/3 f

Then, you are left with: 5f-3 = 1/2

Then you subtract by three on both sides to get: 5f=3.5

Finally, divide by 5 on both sides to get: f=.07
