Answer:

If you mean "How do I write an inequality?", the answer is COEFFICIENTxVARIABLE {any symbol} COEFFICIENTxVARIABLE >/< INTEGER

In other words, you should have something like this: -3x + 4v < 63

Or this: 51x - 16v > 11

Or anything along those lines.

Mr. McCoy is planning to install a circular pool. The circumference of the pool is 25 feet. What is the area sow your work

ivolga24 [154]

Answer: Area of circular pool is 47.8 ft².

Step-by-step explanation:

Since we have given that

Circumference of the pool = 25 feet

Let the radius of circular pool be 'r'.

As we know the formula for "Circumference of pool":

$C=2\pi r\\\\25=2\times \frac{22}{7}\times r\\\\\frac{25\times 7}{2\times 22}=r\\\\3.9\ ft=r$

So, Area of circular pool will be

$Area=\pi r^2\\\\Area=\frac{22}{7}\times 3.9\times 3.9\\\\Area=47.8\ ft^2$

Hence, Area of circular pool is 47.8 ft².

WHATS X AND Y?? Y = 3x+ 4 and 2x – 4y = -6

Georgia [21]

Answer:

X=-1, y=1

Step-by-step explanation:

Substitute value of y in first equation (3x+4) with y of second equation.

2x-4(3x+4)=-6

2x-12x-16=-6

-10x=10x=-1

solve for y but putting -1 for x value in either equation

y=3(-1)+4

y=-3+4

y=1

The slope of the given line is:

777dan777 [17]

Explaining the Concept:

We need to find the slope of the given line:

We know that Slope of a line = Rise/Run. So, to calculate the rise and the run, we will use the points (0,4) and (2,0) on the line

Finding the Slope:

Rise:

We know that the rise of a line is its change in y-coordinate

So, rise of the given line = y₂ - y₁

Rise = 0 - 4 [Since y₁ = 4 and y₂ = 0]

Rise = -4

Run:

We know that the run of a line is its change in x-coordinate

So, Run = x₂ - x₁

Run = 2 - 0 [Since x₁= 0 and x₂ = 2]

Run = 2

Slope:

As we said before,

Slope = Rise/Run

replacing the variables

Slope = -4/2

Slope = -2

Hence, the slope of the given line is -2

If line T is a transversal of lines I and m, name the angel relationship of the given angle pairs

Crazy boy [7]

Answer:

a.Corresponding angles

b.Alternate exterior angles

c.Consecutive interior angles

Step-by-step explanation:

a. $\angle 1,\angle3$ are corresponding angles.

Two angles on the same side of the transversal either below or above of the two lines are corresponding angles.

b. $\angle 4,\angle8$ are alternate exterior angles.

Pair of angles in which one arm of each of the angles lies on opposite sides of the transversal.

c. $\angle 2,\angle3$ are consecutive interior angles.

Consecutive interior angles are also called co-interior angles.

Angles which are lying on the same side of a transversal cutting across the the two lines which are parallel.

So the pair of $1\ and\ 3$ are corresponding angles the pair of $4\ and\ 8$ are alternate exterior angles,the pair of $2\ and\ 3$ are consecutive interior angles.
