Answer:
the slope (or rise over run) is 2/3x, and the y intercept is -2
Step-by-step explanation:
In order to find the slope:
- subtract 2x from itself, cancelling it out. Do the same to the other side (-6).
- it should then look like this: 3y=-2x+-6
- next divide 3 from y as well as from -2 and -6.
- it should then look like this: y=2/3x+-2
Answer:
160
Step-by-step explanation:
60% of a + 24 = 3a/4
=> 60a/100 + 24 = 3a/4
=> 3a/5 + 24 = 3a/4
=> 3a / 4 - 3a/5 = 24
=> ( 15a - 12a) / 20 = 24
=> 3a / 20 = 24
=> a = 24 × 20 / 3
=> a = 8 × 20
=> a = 160
22)
(x^2-16)(x^2+4)=0
can you finish?
solve for x (plus and minus because two solution and degreee 4 so total 4 answers )
x=+-4 x=+-2
hope this helps.
for 10 I know a way but it might confuse you
