Answer:
A. 2 real roots: (2, 7) and (1, 4).
Step-by-step explanation:
y = x^2 + 3
y = 3x + 1
So equating the right sides:
x^2 + 3 = 3x + 1
x^2 - 3x + 2 = 0
(x - 2)(x - 1) = 0
So there are 2 roots.
They are x = 2 , y = 3(2) + 1 = 7 and
x = 1, y = 3(1) +1 = 4.

The answer is no
Laura is paying 7% as tax.
1.07 is equal to 107%. To get the total price of something with tax you multiply it by 100% plus the tax. Simplify the percent to 1.07,
1.07x = x + 0.07x
Um okay.
Also, I think it'll be A.
2p = 396/63 (= 6.2857)
p = 198/63 (= 3.14)
