Answer:
x = 1
Step-by-step explanation:
Given :
6x – y = 1
4x – 3y = –11
To Find : the new equation after the expression equivalent to y from the first equation is substituted into the second equation.
Solution :
6x – y = 1 ---a
4x – 3y = –11 ---b
In equation a
y = 6x-1
Now substitute this value of y in equation b
4x – 3(6x-1)= –11
Thus the new equation : 4x-18x+3 = -11
-14x =-14

x=1
Put value of x in equation a
6*1– y = 1
6-y=1
5=y
Thus the solution is (1,5)

Answer:
d
Step-by-step explanation:
90^6=531441000000
80^-4= 1/80^4= 1/4960000
For this, use negative power rule x^-a= 1/x^a
For f(3)...put 3 as the value of x in f(x)
for x.....put the value of f(x) from the given and equate it with 14..and solve
