Answer:
x=-3
y=3
(-3-3i)(3+5i)
Step-by-step explanation:
and we have that must equal
6-24i
3x+5y=6
5x-3y=-24 and if we work it we found out that the solutions are
x=-3 and
y=3
From the equation that was gotten, the value of the pecan pies and the cheesecake will be $9 each.
Based on the information given, the equations to solve the question will be:
9p + 8s = 153 ..... i
2p + 6s = 72 ..... ii
Multiply equation i by 2
Multiply equation ii by 9.
18p + 16s = 306
18p + 54s = 648
Subtract the equations
38s = 342
s = 9
Since 2p + 6s = 72
2p + 6(9) = 72
2p + 54 = 72
2p = 72 - 54.
2p = 18
p = 18/2 = 9
They're both $9 each

Answer:
d = |-9-4| = 13
Step-by-step explanation:
The y-values are the same for the two points, so the distance between them on that horizontal line is the difference of x-values.
d = |(-9) -(4)|
d = |-13| = 13
The distance between the points is 13 units.
