The answer to this question is:
y = -2x - 1
times both sides by 2x
x(x+2)=2(4)
x²+2x=8
minus 8 both sides
x²+2x-8=0
factor
what 2 numbers multiply to -8 and add to 2
-2 and 4
(x-2)(x+4)=0
set to zero
x-2=0
x=2
x+4=0
x=-4
x=-4 and 2
It's not, because it doesn't go through the origin (0,0)

Ok so the P means probability and on the first one c is 1 of 3 of the total number of of letters in the spinner, and so is g
What that means is that they both have 1/3 probable chance of getting picked or 33.3% but it is most likely asking for a fraction so use 1/3
For 5 it’s more difficult
What you have to do is find the probability of heads and tails
Which is 1/2
D is 1/3
And the vowels are A and E which is 2/3
So you would multiply all the fractions and your answer would be ( work; 1/2 x 1/3 x2/3=) 1/18
