Answer:
y = 0.1(4^x)
Step-by-step explanation:
An exponential function can be written as ...
y = a(b^x)
where 'a' is the y-intercept, and 'b' is the ratio of terms with consecutive x-values.
The table tells us a=0.1, and b=0.4/0.1 = 4. The equation is ...
y = 0.1(4^x)

Answer:
3. Option No. 2:
6x + 2y = 22
3x + 3y = 18
4. Option No. 2:
$2.50
Step by step explanation:
4. 6x + 2y = 22
(3x + 3y = 18) * 2
- Negate
6x + 2y = 22
6x + 6y = 36
2y - 6y = 22 - 36
-4y = -14
y = -14/-4
y = 3.5
An order of onion rings = $3.50
- Substitute to find for x
6x + 2(3.5) = 22
6x + 7 = 22
6x = 22 - 7
6x = 15
x = 15/6
x = 2.5
An order of French fries = $2.50
