Answer:
The answer is B.
Step-by-step explanation:
There are two shirts, both cost 10.
10 + 10.
The variable is the cost of the hat, which we add on.
10 + 10 + x.
Finally, 50 is the total price so that is going to be what it equals.
10 + 10 + x = 50
Answer:
f(-3) = 10
Step-by-step explanation:
Simply plug in x as -3 to find f(-3):
f(-3) = -6(-3) - 8
f(-3) = 18 - 8
f(-3) = 10
Answer:
NO SOLUTION
Step-by-step explanation:
Here you're asked to solve a system of equations, linear equations in this case.
Since y = 2x, we can subst. 2x for y in the 2nd equation:
-6x + 3(2x) = 16
Combining the x terms results in 0 = 16, which is never true.
Thus, this system of linear equations has NO SOLUTION.
Answer:
(4,2)
Step-by-step explanation:
The midpoint of PQ = (x1+x2)/2 , (y1+y2)/2
= (0+8)/2 , (0+4)/2
= 8/2, 4/2
=4,2
