P1 = (1,5). P2 = (x,2) .p1p2=5

$\qquad\qquad\huge\underline{{\sf Answer}}♨$

Let's use distance formula :

$\qquad \sf \dashrightarrow \: \sqrt{(x - 1) {}^{2} + (2 - 5) {}^{2} } = 5$

$\qquad \sf \dashrightarrow \: {(x - 1) {}^{2} + ( - 3) {}^{2} } = 5 {}^{2}$

$\qquad \sf \dashrightarrow \:(x - 1) {}^{2} + 9 = 25$

$\qquad \sf \dashrightarrow \:(x - 1) {}^{2} = 16$

$\qquad \sf \dashrightarrow \:(x - 1) = 16$

$\qquad \sf \dashrightarrow \:(x - 1) = \pm4$

$\qquad \sf \dashrightarrow \:x = 5 \: \: or \: \: - 3$

Answer:

D. -7

Step-by-step explanation:

Sum of three times the square of a number and -7.

If we call the number x, then the expression is:

You're at a clothing store that dyes your clothes while you wait. You get to pick from

Art [367]

Answer:

The probability that you'll end up with socks that aren't blue is $\frac{1}{6}$ .

Step-by-step explanation:

The pieces of clothing available:

X = {shirt, pants, socks and hat}

The color options:

Y = {purple, blue and orange}

So, if a person picks a shirt he/she has 3 color options.

Similarly for pants, socks and hat there are 3 color options each.

That makes 12 possible pieces of clothing.

That is, there are 12 total options available.

Now, compute the probability of selecting a socks as follows:

$P(Socks)=\frac{1}{4}$

Compute the probability of selecting the color blue as follows:

$P(Blue)=\frac{1}{3}$

Compute the probability of selecting a socks that are not blue as follows:

$P(Socks\cap not\ Blue)=P(Socks)\times [1-P(Blue)]$

$=\frac{1}{4}\times [1-\frac{1}{3}]$

$=\frac{1}{4}\times \frac{2}{3}$

$=\frac{1}{6}$

Thus, the probability that you'll end up with socks that aren't blue is $\frac{1}{6}$ .

Solving quadratic equations by factoring m(m-3)=0

KatRina [158]

Because it has already been factored, we can solve it straight away. Now, since m is a variable, we yield the same result if m = 0 or m = 3 because we have two components to this equation.

We can either have m = 0 or m - 3 = 0
Hence, m is either 0 or 3
