Pavlova-9 [17]

Answer:

$f(3) = f(3 - 2) \times f(3 - 1)$

$f(3) = f(1) \times f(2)$

$f(3) = 4 \times 25$

$4 \times 25 = 100$

Please help, describe the error in the solving the equation

3. The second line should be $6x = 0$ or $x+5 =0.$

3. So the roots are $x=0$ or $x = -5.$

Step-by-step explanation:

Step 1:

If the function equals 0, we substitute all the separate factors to 0.

We keep the variable on the left side while all the other values go to the right side.

The given equation is $6x (x+5)= 0.$

Step 2:

As given in step 1, we substitute all the separate factors to 0.

So $6x = 0$ or $x+5 =0.$

So the roots are

$6x = 0, x = \frac{0}{6} = 0, x = 0.$

$x+5=0, x = 0-5=-5, x=-5.$

So the roots are $x=0$ or $x = -5.$

Solve. −3/5x + 1/5 > 7/20 Drag and drop a number or symbol into each box to show the solution.

Answer:

x < -1/4

Step-by-step explanation:

−3/5x + 1/5 > 7/20

Subtract 1/5 from each side

−3/5x + 1/5-1/5 > 7/20-1/5

Get a common denominator

-3/5x > 7/20 -1/5*4/4

-3/5 x > 7/20 -4/20

-3/5x > 3/20

Multiply by -5/3 to isolate x

When we multiply by a negative it flips the inequality

-5/3 *-3/5x < -5/3 *3/20

x < -5/20

x < -1/4
