Answer:
a. y = 3 × 0 + 15
y= 0+15
y= 15
Step-by-step explanation:
Subtitute the variables into the place they are denoted with and solve it
And the place where the equation will cross the y axis is just the last numbers i.e. 15 and 3z which is 6

Y is 15 :)
Explanation:
If you divide 3/2, you get 1.5. 15/10 is also get 1.5
Another way of doing this is by cross multiplying. Multiply 3 by 10 to get 30 on the right side of the equation. Multiply 2 by y to get 2y. Then divide both sides by 2 and you get y = 15.
[x-(-1+i)][x-(-1-i)]
[(x+1)-i][(x+1)+i]
(x+1)²-i²
(x²+2x+1)+1
x²+2x+2
so the answer is 2x
