Answer:
D) x^2+2
Step-by-step explanation:
(2x^2+2x+3)-(x^2+2x+1)
2x^2-x^2+2x-2x+3-1
x^2+3-1
x^2+2
Answer:
y = 2x - 1 is the required equation
Step-by-step explanation:
slope(m) = (3-7)/(2-4)
m = -4/(-2)
so, m = 2
Now,
y = mx + b
or, y = 2x + b
so, 3 = 2*2 + b
or, 3 = 4 + b
so, b = -1
equation would be y = 2x - 1
8-x(y)
or in words 8 minus x times y do the 8 minus x first then the times y
