Add two exponents

For example, take 2 x 10^4, which is 20,000. This is equal to 2,000,000%, or 2 x 10^6.

All you do is change 2 x 10^4 to 2 x 10^6%.

The equation of the function is Y=4x+5.Find the value of y when<br> x=3<br> x=-2

natita [175]

The equation of the function is y = 4x + 5. Find the value of y when

x = 3

x = -2

<h3>Given:-</h3>

y = 4x + 5 [Equation]

The value of y when x = 3 , x = -2

<h2>Solution:-</h2>

y = 4x + 5 [Given equation]

$\therefore$ When x = 3 ,

y = 4 × 3 + 5 [Value of x is 3]

y = 12 + 5

<h3>y = 17 [Answer]</h3>

Again, when x = -2 ,

y = 4 × (-2) + 5 [Value of x is -2]

y = -8 + 5

<h3>y = -3 [Answer]</h3>
