It looks like your just adding on 2 more.
The first question is 0.5×7. The second is 10,819.00 Japanese yen.
Answer:
D
Step-by-step explanation:
This questions asks use to find what f(x) or y is, when x is equal to -2.
So, substitute -2 in for x in the equation.
f(x)=2(4)^x
f(-2)=2(4)^-2
Evaluate the exponent. Negative exponents follow this rule:
b^-x= 1/b^x
We have 4^-2. This will become 1/4^2 or 1/16
f(-2)=2(1/16)
Multiply
f(-2)=2/16
This fraction can be simplified. Both the numerator (top number) and denominator (bottom number) can be divided by 2.
f(-2)=2/2 / 16/2
f(-2)= 1/8
The correct choice is D. 1/8

Hope this helped! Have a great day!!
Explanation:
The equation is already in standard form.
A is 1. The number 1 is often unwritten.
B is -3. The negative or positive sign is included with the equation.
C is -6. (If using this for the quadratic formula, c is actually 6 because the equation should equate to 0).
