Step-by-step explanation:
Pie= 3.14
3.15 x 5 x 6= 94.2
the
first equation is the answer of this question.
explanation
where the xy is in sequence so it is the standard form of polynomial
Answer:
(-1,2)
Step-by-step explanation:
y = -2x ______(1)
7x - 8y = -23 ________(2)
Substituting the value of y in eqn.(1) into eqn (2);
7x - 8(-2x) = -23
7x + 16x = -23
23x = -23
x = -1
y = -2(-1) = 2.
