The solution to the inequality $3x-3\leq -15\,\,or\,\,4x-1\geq 11$ is $x\leq -3\,\,or\,\,x\geq 4$

The number line is shown in figure attached.

Step-by-step explanation:

We need to solve the inequality: $3x-3\leq -15\,\,or\,\,4x-1\geq 11$

Solving the inequality:

$3x-3\leq -15\,\,or\,\,4x-1\geq 11\\Adding\,\,3\,\,on\,\,both\,\,sides\,\,and\,\,1\,\,on\,\,both\,\,sides\\3x-3+3\leq -15+3\,\,or\,\,4x-1+1\geq 11+1\\3x\leq -12\,\,or\,\,4x\geq 12$

Divide by 3 and divide by 12

$x\leq \frac{-12}{3} \,\,or\,\,x\geq \frac{12}{4} \\x\leq -4\,\,or\,\,x\geq 3$

So, value of x can be less than equal to -4 or value of x is greater than equal to 3.

The number line is shown in figure attached.

the height of a kicked soccer ball is represented by the function f(x)=8x-2x^2 where x is the number of seconds since the ball w

____ [38]

Answer:

Result at time x = 4 seconds the soccer ball hit the ground.

Step-by-step explanation:

At the moment just before the ball is kicked, it is on the ground and so the height f(x) is zero meters. After the kick, the ball goes through the air and it's path can be described by a (mountain) parabola.

So lets see after how many second (x) the height = 0 once again.

f(x) = 8x-2x^2

f(x) = 0

8x - 2x^2 = 0

Try to write the formula in two terms

-2x * (x - 4) = 0

When a product of two or more terms equals zero, then at least one of the terms must be zero.

Now solve each term = 0 separately, meaning, solve as many equations as there are terms in the product.

Any solution of term = 0 solves product = 0.

Solve the first term:

-2x = 0

Multiply left an right from the = singn with the factor -1 gives this outcome:

2x = 0

x = 0

Solve the second term:

x-4 = 0

x = 4

Result at time x = 4 seconds the soccer ball hit the ground.

x = 4

x = 0
