<u>Step</u><u> </u><u>by</u><u> step</u><u> explanation</u><u>:</u>

Step 1:

4w² − v + 3u

Step 2:

=  {4( - 4)}^{2}  - 5 + 3 \times 2

Step 3:

= 4(16) - 5 + 6

Step 4:

= 64 - 5 + 6

Find an equation of variation in which y varies directly as x and y = 60 when x = 0.4. Then find the value of y when x = 2​
Nostrana [21]

Answer:

y = 300

Step-by-step explanation:

The equation of variation in which y varies directly as x is written Mathematically as:

y ∝ x

y = k × x

y = kx

Where k = Proportionality Constant

We find k

a) y = 60 when x = 0.4.

60 = 0.4 × k

k = 60/0.4

k = 150

b) find the value of y when x = 2​

y = kx

k = 150

Hence,

y = 150 × 2

y = 300
