Answer:
Step-by-step explanation:
we can write -9 instead of x and y=1 instead of 1
so we write solution again
-9a+1b=-31
-9a-1b=-41
-18a=-72
a=4
we should write 4 instead of a
-9(4)+1b=-31
-36+b=-31
b=5
a=4
Answer:
$y=(7/2)x+20$
Step-by-step explanation:
SInce the gradient of the first line is $-2/7$ then the gradien of the perpendicular line is $7/2$.
Therefore by the point slope formula the line that we are looking for is
$y-6=(7/2)(x+4)$
$y=(7/2)x + 20$
Answer:
1) 6+4x and 5+3x. 2) 3+6x and 10+2x. 3) 15+4x and 2+3x
Step-by-step explanation:
finding area is just multiplying the sides so find numbers that multiply to make 30 and 12
Answer:
- 6x³ - 1
Step-by-step explanation:
Substitute x = g(x) into f(x), that is
(f ￮ g)(x)
= f(x³ )
= - 6(x³) - 1
= - 6x³ - 1
