Step-by-step explanation:

To solve a system of equations by substitution, you can solve one of the equations for one of the variables and substitute this expression into the other equation. This will give you an equation with only one variable, which you can then solve to find the value of that variable. You can then substitute this value back into one of the original equations to find the value of the other variable.

In this case, the given system of equations is:

y = -4

y = -2x - 20

Since the second equation is already in the form y = ..., we can substitute the expression for y from the second equation into the first equation:

-4 = -2x - 20

Solving this equation for x, we get:

x = -12

Substituting this value of x back into the second equation, we get:

y = -2(-12) - 20

= 24 - 20

= 4

Therefore, the solution to the system of equations is (x, y) = (-12, 4).

Answer:

x = -8

Step-by-step explanation:

-2x - 20 = -4

-2x = 16

x = -8

Rise and Run of line's ratio gives the Slope of the line.

Rise of a line is the how many units you move up or down to reach from one point to another point. Run of a line is the how many units you move left or right to reach from one point to another.

>Slope of a line is the ratio of the rise to the run of the line.

Let us assume the graph of y = x.

Now in the graph we take three points

let point 1 be (3,3) = (x1,y1)

    point 2 be (5,5)= (x2,y2)

    point 3 be (5,3)= (x3,y3)

Now the rise is y2  -  y1 which is 2

Now the run is x2 - x1 which is 2

Slope is [tex]\frac{rise}{run}[/tex]  = [tex]\frac{2}{2} =1[/tex], we know that slope of line y=x is 1 and here we get the same so it is proved that slope of line is  [tex]\frac{rise}{run}[/tex] .

The continuous data that is presented as a frequency distribution makes up the median of the grouped data.

The center number in the set of data, known as the median, is what divides the data set's upper and lower halves. Since the data is divided into class intervals, the middle value is unknown when calculating the median of grouped data.

Let us understand this with the help of a median class example.

Consider the data as 48, 20, 59, 69,73. We have to calculate the median.

Arranging in ascending order we get, 20, 48, 59, 69, 73.

Here the number of observations is n = 5.

To find the median of odd data we will use the formula:

[(n+1)/2] = (5+1)/2 = 3.

Therefore, median = 3rd observation.

Median = 59.

Hence we got the idea of the median with the example of class.

As given in the question,

Given polynomial is equal to :

3x²+ 4x + 2k

-2 is the zero of the given polynomial 3x²+ 4x + 2k

Compare with the standard quadratic equation ax² + bx + c

Let 'α' be the zero whose value is equal to -2.

And 'β' be the another zero.

Sum of the zeros of the polynomial = -b/ a

ASA Stands for Angle - Side - Angle.

There are three theorems that may be used to determine whether two triangles are similar: Angle - Side - Angle (ASA), Side - Angle - Side (SAS), and Side - Side - Side (SSS).

SSS, which stands for "side, side, side," denotes that there are two triangles with identical angles on all three sides. The triangles are congruent if their third sides are the same as those of another triangle.

That is what the SAS regulation says. The triangles are congruent if the two sides and included angle of one triangle are the same as the two sides and included angle of another triangle. Any angle that is created by two specified sides is an included angle.

Answer:

Number of muffins= 18

Number of beverages= 14

Amount spent on muffins= $63

Amount spent on beverages= $24.50

Step-by-step explanation:

To find the number of muffins sold, we can first assume that all the 32 items purchased were beverages.

If the class bought 32 beverages,

Total spending

= 32($1.75)

= $56

Difference in total spending

= $87.50 -$56

= $31.50

The difference in the total spending is due to the number of muffins purchased that we had assumed they were beverages.

Difference in cost for each muffin vs beverage

= $3.50 -$1.75

= $1.75

Thus, for every incorrect assumption we made, the total spending will be $1.75 lesser than the actual amount.

Sets of wrong assumption

= $31.50 ÷$1.75

= 18

This means that out of the 32 items we previously assumed to be beverages, 18 were actually muffins. The remaining number of items were indeed beverages.

Number of muffins= 18

Number of beverages

= 32 -18

= 14

Amount spent on muffins

= 18($3.50)

= $63

Amount spent on beverages

= 14($1.75)

= $24.50

Total spending

= $63 +$24.50

= $87.50

What is a Line Segment?

A line segment is a portion of a straight line that is defined by two points. It is a one-dimensional geometric figure with no width or area. Line segments can be drawn in many ways, including straight, curved, or jagged. The length of a line segment is the distance between the two points that define it. Line segments are commonly used to measure distances, form shapes, and construct geometric figures. Line segments can be used to define polygons, circles, and other shapes. Line segments are also used in mathematics to represent vectors and calculate angles. Line segments are a fundamental element of geometry and are used in a variety of applications, including navigation, construction, engineering, and computer graphics.

Answer:

1) x = 29; m∠3 = 6º

2a) scalene

2b) acute

Step-by-step explanation:

1) We can first solve for m∠3, as it is supplementary to 174º.

174º + m∠3 = 180º

m∠3 = (180 - 174)º

m∠3 = 6º

Then, we can solve for x by setting the sum of the measures of the interior angles of the triangle to 180º.

m∠1 + m∠2 + m∠3 = 180º

↓ substitute in given and solved values

(3x + 2)º + (5x - 60)º + 6º = 180º

↓ combine like terms

8xº - 52º = 180º

↓ add 52 to both sides

8xº = 232º

↓ divide both sides by 8º

x = 29

2a) We know that this triangle is not equilateral, as the measure of one of its interior angles (m∠3) is 6º. However, the triangle may be isosceles if m∠1 = m∠2. We can check for that by substituting x into each angle measure expression.

m∠1 ≟ m∠2

(3x + 2)º ≟ (5x - 60)º

↓ substitute in x-value

3(29)º + 2º ≟ 5(29)º - 60º

↓ simplify

(87 + 2)º ≟ (145 - 60)º

89º ≠ 85º

m∠1 ≠ m∠2; the triangle is not isosceles. Therefore, it must be scalene.

2b) All of the triangle's angles are less than 90º. Hence, it is an acute triangle.
