This can be done in two ways
One method is to check the answer options in both f(x) and g(x) and select the one that matches for both.
The second is to form a quadratic equation and solving as such:
f(x) = g(x)
-x² + 4x + 12 = x + 8
x² - 3x - 4 = 0
(x - 4)(x + 1) = 0
x = 4; x = -1
Only x = 4 is given in the options, so the answer is B
Answer:
Step-by-step explanation:
Let c ----> Cat
t ------> Table
f ---------> Frog
From the first figure,
c + t -f = 170 -----------(i)
From the second figure,
f + t -c = 130 ---------(ii)
Add (i) and (ii)
(i) c + t -f = 170
(ii) <u>f + t -c = 130</u> {c & -c and f & -f gets cancelled
2t = 300
t = 300/2
t = 150 cm
The table is 150 cm tall
Answer:
Step-by-step explanation:
five times a number increased by nine is
5x+9
x is the unknown number being multiplied by 5
increase= add
so add by 9

Answer:
an = (-3)^(n-1).
Step-by-step explanation:
The formula for the nth term an = a1r^(n-1) where a1 = first term and r = the common ratio.
In our series a1 = 1 and r = -3/1 = -3 so the explicit formula is:
1. * (-3)^(n-1)
