5m + 4m = 72
Combine like terms.
9m = 72
Divide both sides by 9.
m = 8
Y=6x
The slope of the equation is six meaning you go up six and over 1 to find the next point.
5 I think I'm not surreeeeee
Answer:
C
Step-by-step explanation:
We can solve this by analyzing if the event causes the result. If it does not, then there is correlation but not necessarily causation
A. Event: Rainfall. Result: Water level rises
Does rainfall cause an increase in water level? Yes, so this is incorrect
B. Event: Temperature increase. Result: Ice melting
Does an increase in temperature cause ice to melt faster? Yes, so this is incorrect
C. Event: More people have vision loss. Result: Hearing aids sales increase
Does more people having vision loss cause hearing aids sales to increase? No, vision loss does not cause a need for hearing aids -- hearing loss would, but vision loss does not. This is correct
D. Event: A student makes fewer mistakes. Result: A better grade
Do fewer mistakes cause better grades? Yes, so this is incorrect
1) You need to work this problem backwards.
x=0 and x=5 and those are the roots so the factoring must have looked something like this:
(x-0)(x-5) Then you would FOIL it:
x^2-5x-0-0 Then simplify:
x^2-5x.
2) Do the same thing with this problem.
x=7 and x=7
(x-7)(x-7)
x^2-7x-7x+49
x^2-14x+49
I hope that this helps.
