remember that you have to do the same to both sides

$\frac{x}{4}+16>34$

minus 16 both sides

$\frac{x}{4}+16-16>34-16$

$\frac{x}{4}+0>18$

$\frac{x}{4}>18$

mulitply both sides by 4

$\frac{4x}{4}>18*4$

$(x)(\frac{4]{4})>72$

$(x)(1)>72$

$x>72$

Bill Gates wrote a computer program that generates three random numbers

Allushta [10]

Answer:

1/1000

Step-by-step explanation:

The probability of two independent events A, B (independent = events that do not depend on each other) is given by the product of the individual probabilities of A and B:

$p(AB)=p(A)\cdot p(B)$ (1)

In this problem, the single event is "getting a 3" when extracting a random number between 1 and 10.

The total number of possible outcomes is

n = 10

While the number of succesfull outcomes (getting a 3) is only one:

$s=1$

So, the probability of drawing a 3 in 1 draw is

$p(3)=\frac{s}{n}=\frac{1}{10}$

Then, we want to find the probability of getting three "3" in 3 consecutive generations. These events are independent events, so we can use rule (1) to find the total probability, and we get:

$p(333)=p(3)p(3)p(3)=(\frac{1}{10})(\frac{1}{10})(\frac{1}{10})=\frac{1}{1000}$

Which of the following expressions is equal to the expression 4x-2(3x-9)? 18-2x,-10x-18,-2x-18,10x-18

nordsb [41]

4x - 2(3x - 9)....distribute the 2 thru the parenthesis
4x - 6x + 18....combine like terms

Move everything to the left by subtracting 25 from both sides:

$81x^2-25=0$

Both terms are squares: $81x^2$ is the square of $9x$ , while 25 is the square of 5. So, we can apply the factoring

$a^2-b^2=(a+b)(a-b)$

To factor the expression as

$(9x+5)(9x-5)=0$

A multiplication is zero if and only if one of the factors is zero, so we have

$(9x+5)(9x-5)=0 \iff 9x+5=0 \lor 9x-5=0 \iff x=-\dfrac{5}{9} \lor x=\dfrac{5}{9}$

2

The discriminant of the quadratic expression $ax^2+bx+c$ is defined as

$\Delta = b^2-4ac$

So, you have

$\Delta = 0^2-4\cdot(-1)\cdot(-25) = -100$

3

Similarly, we have

$\Delta = 7^2-4\cdot(-3)\cdot 6 = 49+72=121$

Solve the equation, and check the solutions √(x+6)=3.

posledela

Answer:

The solution is $x = 3$

Step-by-step explanation:

We have the following equation:

$\sqrt{x+6} = 3$

Elevating both sides to 2, we can isolate x

$\sqrt{x+6}^{2} = 3^{2}$

$x + 6 = 9$

$x = 9 - 6$

$x = 3$

Checking

$\sqrt{x+6} = \sqrt{3+6} = \sqrt{9} = 3$
