$\bf ~~~~~~~~~~~~\textit{middle point of 2 points } \\\\ A(\stackrel{x_1}{-3}~,~\stackrel{y_1}{-5})\qquad B(\stackrel{x_2}{x}~,~\stackrel{y_2}{y}) \qquad \left(\cfrac{ x_2 + x_1}{2}~~~ ,~~~ \cfrac{ y_2 + y_1}{2} \right) \\\\\\ \left( \cfrac{x-3}{2}~~,~~\cfrac{y-5}{2} \right)~~=~~\stackrel{\stackrel{Midpoint}{M}}{(-0.5~,~0)}\implies \begin{cases} \cfrac{x-3}{2}=-0.5\\[1em] x-3=-1\\ \boxed{x= 2}\\ \cline{1-1} \cfrac{y-5}{2}=0\\[1em] y-5=0\\ \boxed{y=5} \end{cases}$

Help needed will give thanks and many more if right lol

Savatey [412]

Answer:

Step-by-step explanation:

The circumference of any polygon is equal to the sum of the lengths of the sides of this polygon.

Therefore

P = 2x + (x + 5) + (4x - 2) combine like terms

P = (2x + x + 4x) + (5 - 2)

P = 7x + 3

Order these from greatest to least 7 7/8, 7.5, 7.8, 7 3/4

Marizza181 [45]

The numbers are ordered from greatest to least is:

$7\frac{7}{8} >7.8 > 7\frac{3}{4} > 7.5$

Solution:

Given numbers are:

$7\frac{7}{8} , 7.5, 7.8, 7\frac{3}{4}$

We have to order them from greatest to least

Let us first convert the mixed fractions number to decimals

Mixed fractions to fractions:

Multiply the whole number part by the fraction's denominator.

Add that to the numerator.

Then write the result on top of the denominator.

Therefore,

$7\frac{7}{8} = \frac{8 \times 7 + 7}{8} = \frac{63}{8} = 7.875$

Similarly,

$7\frac{3}{4} = \frac{4 \times 7 + 3}{4} = \frac{31}{4} = 7.75$

Now the given numbers are:

7.875, 7.5, 7.8, 7.75

Arrange them from greatest to smallest

7.875 > 7.8 > 7.75 > 7.5

Thus the order is:

$7\frac{7}{8} > 7.8 > 7\frac{3}{4} > 7.5$

Thus the numbers are ordered from greatest to least

In the following exercise, find the coordinates of the vertex for the parabola defined by the given quadratic function.

AleksAgata [21]

The vertex is the point at which the parabola or quadratic equation opens up or down. To calculate the parabola, we must use the formula: -b/2a = x; x = -16/2(4) x = -2
Substitute -2 in where you see x appear and do the arithmetic to find that y = -15. Therefore, the vertex coordinates are (-2,-15).
