For each function, what is the output of the given input? . . For f(x) = 4x + 7, find f(4)

1 answer:

7 0

Look at the LHS in f(x) = 4x + 7, ie, f(x). Compare it with f(4). You see that we've put 4 in place of x.
<span>To find f(4), put 4 in place of x in RHS. Simple. </span>

<span>f(4) = 4 * 4 + 7 = 16 + 7 = 23.</span>

If y varies inversely as x and y=3 when x=8 what is x when y=4

I am Lyosha [343]

Answer:

x = 6

Step-by-step explanation:

y varies inversely as x

y = k × 1/x. {where k is a constant}

when y = 3, x = 8

Therefore 3 = k/8 and k is 24

y = 24/x

When y = 4,

4 = 24/x

4x = 24

(dividing both sides by 4)

x = 6

Find the least common denominator of 11/ 70 and 7 /60 . LCD =

drek231 [11]

The least common denominator is 420

<h3>How to find the least common denominator?</h3>

The expressions are given as:

11/70 and 7/60

Factorize the denominator of the fractions.

So, we have

70 = 7 * 10

60 = 6 * 10

Multiply the factors

LCD = 6 * 7 * 10

Evaluate

LCD = 420

Hence, the least common denominator is 420
