Answer:
A.

B. 343 • 7^x
Step-by-step explanation:
if the base of two exponential number is same we add their powers up (only when multiplying)
7^3+7^x ➡7^3+x
the expansion of 7^3 = 343 so 343•7^x is also equivalent to the given expression.

Answer:

Step-by-step explanation:
Slope/Gradient = 
P = (-8 , 3) (x1, y1)
Q = (-6 , 2) (x2, y2)
Slope =

19 quantities of item A and 6 of item B were sold, respectively
<h3>How to determine the quantity sold</h3><h3>The missing information in the question are</h3>
- The cost of item A is $4 and
- The cost of item B is $2.
Using the information and the given parameters, we have the following system of equations:
A + B = 25
4A + 2B = 88
Multiply the first equation by 2
2A + 2B = 50
Subtract this equation from the second equation to eliminate B
2A = 38
Divide both sides by 2
A = 19
Substitute A = 19 in A + B = 25
19 + B = 25
Subtract 19 from both sides
B = 6
Hence, 19 quantities of item A and 6 of item B were sold, respectively
