If f(x) = 2x and g(x) = cos(x), then g(90°)) = ? (1) 1
(3) 0
(2) - square root 2 /2
(4) -1

-1

Step-by-step explanation:

no, the equation would be invalid since they are both not equal.

step-by-step explanation:

here you got

4y-6+4y 2-9

first, you would simplify the equation on the form.

4y-6+4y 2-9

then, move all the terms that contains a y to the left and all the other terms to the right.

+4y-4y+-9-6

finally, you will simplify the left and the right side of the equation.

y=-3
