Answer: 7/8
Step-by-step explanation:
If the ratio is vanilla to chocolate, it would be
42:48
Dividing by 2
= 21:24
Dividing by 3
= 7:8
Answer: $$x(x+4)(x+3)=x(x^2+7x+12)=x^3+7x^2+12x$$.
Step-by-step explanation:
In general, if you want
x
=
c
to be a root of a polynomial, then the polynomial must contain at least one factor of the form
x
−
c
(if
c
<
0
the
x
−
c
can be written as an addition of a positive number).
A. (2,6)(5,0)
slope = (0 - 6) / (5 - 2) = -6/3 = -2
y = mx + b
slope(m) = -2
(2,6)..x = 2 and y = 6
sub and find b, the y int
6 = -2(2) + b
6 = -4 + b
6 + 4 = b
10 = b
so line A , equation is : y = -2x + 10
============================
B. (0,2)(6,6)
slope = (6 - 2) / (6 - 0) = 4/6 which reduces to 2/3
y = mx + b
slope(m) = 2/3
(0,2)...x = 0 and y = 2
sub and find b, the y int
2 = 2/3(0) + b
2 = b
LIne B, equation is : y = 2/3x + 2
=========================
so we have :
y = 2/3x + 2
y = -2x + 10
2/3x + 2 = -2x + 10 ..multiply by 3
2x + 6 = -6x + 30
2x + 6x = 30 - 6
8x = 24
x = 24/8
x = 3
y = -2x + 10
y = -2(3) + 10
y = -6 + 10
y = 4
solution is (3,4).....3/4 is the solution to both lines <===
Answer:
42.66%
Step-by-step explanation:
subtract the amount of money from after and before: 1,635.30 - 1,422 = 213.3
divide the amount of money gained by the years: 213.3/5 = 42.66
