Answers

Answer 1

The angle x of the triangle is 60 degrees.

How to find the angles in a triangle?

A triangle is a polygon with three sides. The sum of angles in a triangle is equals to 180 degrees.

A triangle can be classified base on the sides and angles. For example equilateral triangle, scalene triangle and isosceles triangle.

Therefore, the angle x of the triangle can be found as follows:

x + x + x = 180

3x = 180°

divide both sides of the equation by 3

3x / 3 = 180 / 3

x = 180 / 3

x = 60 degrees.

What is the perimeter of this rectangle?

Answers

The perimeter of the rectangle is 6.89

Perimeter of the rectangle:

The perimeter (P) of a rectangle is the total length of all the sides of the rectangle.

The formula for the perimeter of the rectangle is

P = 2(l + w)

The letter ‘P’ denotes the perimeter of a rectangle. Let l denote the length and w denote the width of the rectangle.

Given,

Here we have the graph with the following points:

(-3/2, -1 7/9), (7/2, -1 7/9), (7/2, 3 2/9), and (-3/2 3 2/9)

Now we need to find the perimeter of the rectangle.

To calculate the perimeter, first we have to find the length and width of the rectangle.

To calculate the length, we have to use the values of x axis,

That is,

=> -3/2 + 7/2

=> (-3+7)/2

=> 4/2

=> 2

Therefore, the length of the rectangle is 2.

Now, we have to find the width of the rectangle using the y axis coordinates,

=> -1 7/9 + 3 2/9

Convert the mixed fraction into normal form, then we get,

=> -16/9 + 29/9

=> (-16 + 29)/9

=> 13/9

Therefore, the width of the rectangle is 13/9

Now, we have to use this to calculate the perimeter of the triangle,

P = 2 (2 + 13/9)

P = 2 ((18+13)/9)

P = 2 (31/9)

P = 62/9

P = 6.89

Therefore, the perimeter of the rectangle is 6.89.

Use the graph or table to find the equation that represents the relationship.

Answers

#1 = y = 3x -5

#2 = y = -12x + 2

Step by step

For #1, I’m using the two points
(1, -2) and (3, 4) to find slope

y2 - y1 over x2 - x1
4- -2 over 3 -1
6 over 2 = 6/2 or slope (m) of 3

Now we find the equation
Using points (3, 4)

y - y1 = m (x - x1)

y -4 = 3(x - 3)

y -4 = 3x -9

Add 4 to each side to solve for y

y - 4 + 4 = 3x - 9 + 4

y = 3x -5

————

For # 2 I’m using the two points
(1/8, 1/2) and (0, 2) to find slope (m)

y2 - y1 over x2 - x1

2 - 1/2 over 0 - 1/8

1 1/2 over -1/8

To simplify we divide 1 1/2 by -1/8

When we divide fractions we flip the divisor and multiply

3/2 * -8/1 = -12 slope (m)

Now we find the equation
Using points (0, 2)

y - y1 = m (x - x1)

y - 2 = -12(x - 0)

y -2 = -12x

Add 2 to both sides to solve for
y -2 +2 = -12x + 2

y = -12x + 2

18 -4

The slope is the Rise/Run, or change in y over the change in x. Pick any two points. I'll choose (2,12) and (18,-4),

Rise = (-4 - 12) = -16

Run = (18 - 2) = 16

Slope = Rise/Run = -16/15, or -1

The equation becomes y = -1x + b

To find b, use any of the points in the equation and solve for b. I'll use (14,0):

y = -1x + b

0 = -1(14) + b

b = 14

The equation is y = -x + 14

Answers

The solution set for the given inequality (2q/5 + 4 < 2q/-9) is q∈(-∞, - 45/7).

What is the solution set?A solution set is a group of values in mathematics that satisfy a given set of equations or inequalities.Any value of a variable that causes the given equation to hold true is a solution. A solution set is a collection of all the variables needed to solve an equation. Due to the fact that 2y + 6 = 14 and 2(4) + 6 = 14, the solution set is 4. You must first enter each value from the domain into the equation to obtain the corresponding range values before you can determine the solution set of an equation with a given domain.From these values, make ordered pairs, and then write them as a set.

So, 2q/5 + 4 < 2q/ - 9:

Now, solve for the solution set as follows:

2 ∙ q/5 + 4 < 2 ∙ q/ - 92 ∙ q/5 + 4 < - 2 ∙ q/92q/5 + 4 < - 2q/9[(2q) + 5∙4]/5 < - 2q/9q ∈ ( -∞, - 45/7)

The line containing the points (14, 15) and (20, 24) crosses the y-axis at what point?

Answers

The linear equation that passes through the points (14, 15) and (20, 24) crosses the y-axis at y = -6.

How to get the y-intercept?

A general linear equation can be written as:

y = m*x + b

Where m is the slope and b is the y-intercept.

If the line passes through two points (x₁, y₁) and (x₂, y₂), then the slope can be written as:

m = (y₂ - y₁)/(x₂ - x₁).

In this case the line passes through (14, 15) and (20, 24) so the slope is:

m = (24 - 15)/(20 - 14) = 9/6 = 3/2

y = (3/2)*x + b

To find the y-intercept we can replace the values of one of the points, like (14, 15)

15 = (3/2)*14 + b

15 = 3*7 + b

15 = 21 + b

15 - 21 = b

-6 = b

The y-intercept is -6.

How far outside the city will they be?

The time when the two trains reach each other is
.

The trains are
away from the city when they reach each other.

Answers

Answer:

1.25 hours.

68.75 miles from the city

Step-by-step explanation:

Eltan's train (E) is travelling 65mph west.

Dmitri's train (D) is travelling 55mph west.

In terms of vectors, we can write E as 65E and D as 55W

The miles travelled by each is a function of time, T, in hours.

Each train's distance is:

E: T*65E

D: T*55W

They are 150 miles apart. They will meet with the combined miles travelled is 150 miles.

150 miles = T*65E + T*55W

150 miles = T(120 miles/hour)

T = (150 miles/120 miles/hour)

T = 1.25 hours

Make Demitri's train mile 0 and Eitan's train at mile 150 at the start.

They will have travelled the following miles in 1.25 hours:

Demitri: (1.25hr)(55 m/hr) = 68.75 miles

Eitan: (1.25hr)(65 m/hr) = 81.25 miles

Total = 150 miles

Dimitri is headed away from the city. After 1.25 hours, his train will have travelled 68.75 miles when he sees Eitan passing him on the adjacent track (hopefull) headed into the city. They meet 68.75 miles from the city.

The equation of the line in slope-intercept form would be; y = -12x + 18

How to get the slope-intercept form of a straight-line equation?

If the slope of a line is m and the y-intercept is c, then the equation of that straight line is given as:

y = MX +c

To find the slope of a line, we the rate at which the value of 'y' is increasing as we increase the value of 'x' by one unit.

We have been given the point (1,6) and (2,-6)

y-y₁ = m(x-x₁)

m = (-6-6)/(2 -1)

m = -12/1

Now substitute;

y-y₁ = m(x-x₁)

y- 6 = -12(x- 1)

y- 6 = -12x + 12

y = -12x + 18

Hence, the equation of the line in slope-intercept form would be; y = -12x + 18
