Answer:
Step-by-step explanation:
Here you're being asked to recall your own experience in paying for "value meals." How much have you paid per meal?
If each meal costs $6.50, then 5 would cost $13.00 before tax, and
(1.07)(5)($13.00), or $69.55 total.
Note that there's not just one possible total cost, and that we don't know much about this situation but must insert reasonable values, such as a $6.50 per meal unit cost and a 7% tax rate.
Answer:
y = 13
Step-by-step explanation:
An exponential function has the form
y = a 
To find a and b use the given points
Using (0, 13), then
13 = a 
, since = 1, then
a = 13, thus
y = 13
using (2, 325) , then
325 = 13 b² ( divide both sides by 13 )
25 = b² ( take the square root of both sides )
5 = b
y = 13 × 
← is the exponential function
Step-by-step explanation:
c) since m = undefined => the equation is
x = -2
d) the equation is
y-2= -1/7 (x+7)
=> y = -1/7 x -1+2
<=> y = -1/7 x + 1

Answer:
B
Step-by-step explanation:
Given
2(5x + 8) = 6x + 20 ← distribute parenthesis on left side
10x + 16 = 6x + 20 ( subtract 6x from both sides )
4x + 16 = 20 ( subtract 16 from both sides )
4x = 4 ( divide both sides by 4 )
x = 1 → B
