1. -4 times 3 and 21
2.add -12 and -84
3.-96 dived by 2
4 equals -48
The linear rule should look like this y=a*x+b
As the function graph goes through the (0,0) point, the equation 0=a*0+b <=> b=0 must be true.
Now we only need to find a, using one of the points given. With (-4, 16):
16=-4*a <=> a=16/-4 <=> a= -4
So the rule looks the following way:
f(x)= -4*x
0.25 ....decimal
3/4, 3:4....ratio
2/3 = 6/9....equivalent fractions, fractions
4/8 --> 1/2....equivalent fractions,fraction,simplest form
Answer: 25
<u>Step-by-step explanation:</u>
7(x - y) - 3(2 + 2x)
= 7x - 7y - 6 - 6x
= x - 7y - 6
for x = 3, y = -4
3 - 7(-4) - 6
= 3 + 28 - 6
= 31 - 6
= 25
