Answer:

G(-3, 6)

Step-by-step explanation:

$midpoint = ( \frac{x1 + x2}{2} , \frac{y1 + y2}{2} )$

Substitute the coordinates of M and D into the formula:

$( - 1,5) = ( \frac{x1 + 1}{2} , \frac{y1 + 4}{2} ) \\- 1=\frac{x1 + 1}{2}& ,&5&= \frac{y1 + 4}{2} & \\ - 1(2)= x1 + 1&, & 5(2) &= y1 + 4 &\\ - 2= x1 + 1&, &10 &= y1 + 4 &\\ x1= - 2 - 1&,& y1 &= 10 - 4 &\\ x1= - 3&, &y1& =6 \: \: \: \: \: \: \: \: \: \: &$

Thus, the coordinates of G is (-3,6).

Serhud [2]

We have $\frac{5}{12}$ of 252 people who have a personalized black disc

Number of people who would have personalized flying disc = $\frac{5}{12}*252= \frac{2*252}{12}=105$ people

Then we work out the number of people who like to play disc golf:
$\frac{25}{175}*105= \frac{25*105}{175}=15$ people

So we have 15 people who like to play disc golf and have personalised black disc.

How do you solve an inequality that has a fraction (with a variable as the nemurator/demoninator

vichka [17]

Answer:

Solving with an equality is just simply the same as solving any algebra equations. If you were given a fraction, then just multiply both sides.

Example:

4 + $\frac{x}{2}$ > 14

Subtract 4 on both sides:

4 - 4 + $\frac{x}{2}$ > 14 - 4

$\frac{x}{2}$ > 10

Now multiply both sides by 2:

$\frac{x}{2}$ × 2 > 10 × 2

x > 20

Please answer ASAP. The question is down below

Nadusha1986 [10]

Answer: 1) D 2) B

Step-by-step explanation:

1) The denominator cannot equal zero, Factor the denominator to find the zeros. n³ - 4n² + 3n = 0

n(n - 3)(n - 1) = 0

n=0 n-3=0 n-1=0

n=0 n=3 n=1

2) In order to be a rational expression, it must be in the form $\dfrac{a}{b}$ where both a and b are integers.

Since $\sqrtb$ $\sqrt b$ is irrational and not an integer, then the expressions containing an irrational term after simplified cannot result in an integer.

Therefore, options (i) and (iv) are not rational expressions.

Option (iii) contains b as an exponent. Since there is no information about b, it could be a fraction, which means it could be an irrational number.
