Answer:
x = - 4, x = - 3
Step-by-step explanation:
To find the zeros equate f(x) to zero, that is
x² + 7x + 12 = 0
To factorise the quadratic
Consider the factors of the constant term (+ 12) which sum to give the coefficient of the x- term (+ 7)
The factors are + 4 and + 3, since
4 × 3 = 12 and 4 + 3 = 7, hence
(x + 4)(x + 3) = 0 ← in factored form
Equate each factor to zero and solve for x
x + 4 = 0 ⇒ x = - 4
x + 3 = 0 ⇒ x = - 3
Answer:
(-9, 9)
Step-by-step explanation:
(Given)
-1 -1 (Getting "x" alone)
(Cont. Getting "x" alone)
÷6 ÷6 ↓
↓
(9 and -9 squared are both equal to 81)
↓ ↓ ↓
x = 9 x = -9 (Answer)

We have that
using a graph tool
see the attached figure
case A) <span>f(x) = 4^x
</span>this function is not <span>represented in the graph
case B) </span><span>f(x) = 4^(x) − 3
</span>this function is not represented in the graph
case C) <span>f(x) = 4^(x) + 3
</span>this function is represented in the graph
case D) <span>f(x) = 4^(x + 3)
</span>this function is not represented in the graph
the answer iscase C) f(x) = 4^(x) + 3
Let a be aluminum and g be gold and k how many times:
2*10⁻¹mg a+ 6*10¹mg g= 154 lb
so a=kg
k=a/g
k=2*10⁻¹/6*10=1/300
a=1/300g
so Aluminum is 1/300 of gold.
Jason will need to use 9 more 1/3 gallon-ful pitchers to fill the rest of the empty 3/4 gallon water jug. You convert the two fractions so they have the same denominator (1/12 and 3/12). Then you add the remaining amount of 1/12's to complete 12/12, or 1.
