Last trig explain how to do youuu

See the verification below.

Step-by-step explanation:

Starting expression:

Extract from the expression on the left of the equal sign the common factor "sin(x)":

Now use the Pythagorean trigonometric identity: to replace the expression in between square brackets with "1":

Therefore we have verified the identity

answer

explanation

the given function is

this function has y-intercept at

-4 and a slope of 2.

note that, the graph has a positive slope.

the graph that represents this function is the straight line that moves upward from left to right.

the graph touches the y-axis at -4.

the correct choice is the graph shown in the attachment.

it's equivalent, so we can say that its equal.

let's call the denominator x and the numerador is 18 less then denominator, x - 18.

multiply

2.x = 5.(x - 18)

2x = 5x - 90

90 = 5x - 2x

90 = 3x

x = 90/3

x = 30

so:
