The graph will cross at the coordinates (-2, 9)
<h3>How to solve equations?</h3>
y = 3x + 15
y = 3 - 3x
y = 3x + 15
Hence,
when x = 2
y = 3(2) + 15 = 21
when x = 0
y = 3(0) + 15 = 15
y = 3 - 3x
when x = 2
y = 3 - 3(2)
y = 3 - 6
y = -3
when x = 0
y = 3 - 3(0)
y = 3
Therefore, let's check if the equation will cross.
y = 3x + 15
y = 3 - 3x
using substitution,
3 - 3x = 3x + 15
3 - 15 = 3x + 3x
- 12 = 6x
x = -12 / 6
x = -2
y = 3 - 3(-2)
y = 3 + 6
y = 9
Therefore, the graph will cross at the coordinates (-2, 9)

Answer:
27
Step-by-step explanation:
If you have an exponent that is a fraction, you need to make a radical with the index from the denominator and an exponent of the radicand from the numerator.
(243)^3/5=(![\sqrt[5]{243}^3](https://tex.z-dn.net/?f=%5Csqrt%5B5%5D%7B243%7D%5E3)
)
This would come out as ![\sqrt[5]{14348907^}](https://tex.z-dn.net/?f=%5Csqrt%5B5%5D%7B14348907%5E%7D)
. this further simplifies down to the final answer of 27

Answer:
110
Step-by-step explanation:
z is apparently 10 times x.
10 times 11 is 110.
