Answering your question on "9 students can make a poster in 10 hours. How many students should join them so that they all together can make this poster in 6 hours" its 13 students
f(x)=-3x^2-1
f(-2)= -3(-2)²-1=-3·4-1= - 13
y=-2x+4
y=-8x-6
y=3x+5
y=x-10
y=4x-4
Step-by-step explanation:
these questions require a series of equations in order to solve but if you are asking for them to be rearranged
Answer:
x < 7
Step-by-step explanation:
First apply the -2 onto each term that it is being multiplied onto.
-2x + 6 > - 8
Now subtract six from both sides.
-2x > -14
Now divide by -2.
x < 7
<u>REMEMBER</u>
When doing greater than and less than equations like this, if you divide by a negative you must flip the greater than/less than.
