Hey there!!

Given :

f( x ) = 7 - x

What is f(x)?

f(x) is basically the y.

The question states :

y = 7 - x

Now, find ( 3 )

This states that, I have given the value for x and find y.

y = 7 - x

y = 7 - 3

y = 4

Hence, f(3) = 4

Hope helps!

f(3) means you replace x with 3.

f(x) = 7-x

f(3) = 7-3

f(3) = 4

Solve the expression 9.50h+60=460

zysi [14]

9.50h+60=460
subtract 60 from both sides
9.50h=400
divide both sides by 9.50
h=42.105263
round to the nearest hundredth
h=42.11

The lines given by the equations y=4x and y=0.25x are

d1i1m1o1n [39]

They are not parallel because the slopes are different (slope of 4 and slope of 0.25)

Neither are they perpendicular. If they were then m1*m2 ( the product of their slopes) would be -1 ). The product of these slopes = 4*0.25 = 1)

So choice A is the correct one.
