The slope-Intercept form of the given line is y=1.5x.

A line is a one-dimensional shape that is straight, has no thickness, and extends in both directions indefinitely. The equation of line is given by,

y =mx + c

where,

x is the coordinate of the x-axis,

y is the coordinate of the y-axis,

m is the slope of the line, and

c is y-intercept.

The given line passes through (4, -2) and (2, 3). Therefore, the slope of the given line can be written as,

Slope of the line, m = (-2 - 3)/(4 - 2)

                                = 3 / 2

                                = 1.5

Now, the equation of the line passing through (2, 3) can be written as,

y = mx + c

(3) = 1.5(2) + C

3 = 3 + C

3 - 3 = C

C = 0

Substitute all the value in the equation of the line,

y = m(x) + c

y = 1.5(x) + 0

y = 1.5x

Hence, the equation of the given line is y=1.5x .

Answer:

(-3,1)  & (3, -1)

Step-by-step explanation:

Solving quadratic equation and linear equation:

2x² + y² = 19 -----------------(I)

x + 3y = 0 -----------------(II)

         x = -3y --------------(III)

Substitute x = -3y in equation (I) and we can find the value of y.

2(-3y)² + y² = 19

2*9y² + y²  = 19

  18y² + y² = 19

Combine like terms,

          19y² = 19

             y² = 19 ÷ 19

              y² = 1

              y = √1

              y = ±1

Substitute y = ±1 in equation (III) and find the value of x.

When y = 1,

              x = -3*1

              x = -3

When y = -1,

               x = -3*(-1)

             x = 3

Solutions:  (-3, 1) ; (3, -1)                  

If n is negative the value of the equation that we have below would be -18

We have to rewrite the equation in a way that it would be easier to understand first.

[tex]\frac{-2n+8}{4} =11[/tex]

Next we would have to cross multiply

this would give us

-2n + 8 = 11 * 4

-2n + 8 = 44

take the like terms

-2n = 44 - 8

-2n = 36

divide through by -2 from the above

-2n / -2 = 36 / -2

n = - 18

Therefore given that we have that the value of the equation after n is negative is -18.

The point (8, 6) represents that when there was 8 cm rainfall the plant grew 6 mm. When the plant grew 12 mm in one season, there were 16 mm rainfall

The graph shows the proportional relationship between rainfall during the growing season and seasonal growth of a type of plant

The x axis represents the rainfall during the growing season and y axis represents the seasonal growth of a type of plant.

The point (8, 6) represents that when there was 8 cm rainfall the plant grew 6 mm.

8 represent the x axis measurement and 6 represent the y axis measurements

When the plant grew 12 mm in one season, there were 16 mm rainfall

Hence, the point (8, 6) represents that when there was 8 cm rainfall the plant grew 6 mm. When the plant grew 12 mm in one season, there were 16 mm rainfall

The complete question is:

Step-by-step explanation:

The measure of angles A, B , C and D°are 36°, 63°, 71° and 111° respectively

To find the measure of angles of A, B, C and D, you need to apply some of the angle geometry concepts as follows:

1. m<A

(x+24)° and A = 3x

Since alternate angles are equal, thus:

3x° = (x+24)°

3x -x = 24

2x = 24

x =24/2 = 12

Also, A = 3x = 3(12) = 36°

2. m<B

B = 10x-27 and 7x

Since corresponding angles are equal, thus:

10x -27 = 7x

10x -7x = 27

3x = 27

x = 27/3 = 9

Also, B = 10x -27 = 10(9) -27 = 90-27 = 63°

3. m<C

C = (5x+1)° and (6x-13)°

Since corresponding angles are equal, thus:

(5x+1)° =  (6x-13)°

6x -5x = 13+1

x = 14

Also, C = 5x+1  = 5(14) + 1 = 70+1 = 71°

4. m<D

(6x+3)° and D = (4x+39)°

Since alternate angles are equal, thus:

6x+3 = 4x+39

6x-4x = 39-3

2x=36

x = 36/2 =18

Also, D = 4x+39 = 4(18) + 39 = 72+39 = 111°

Therefore, the m<A = 36°, m<B = 63°, m<C = 71° and m<D =111°. Since B, A,  H and E correspond to m<A, m<B, m<C and m<D respectively, so type BAHE in the answer box

Answer:

B. 35

Step-by-step explanation:

Because lines m and n are parallel, we know that x+(4x+5)=180.

So all you have to do is simplify.

x+(4x+5)=180

5x+5=180

5x=175

x=35

So the only possible value of x is 35

The positive slope is tilted towards the right on a coordinate plane and the negative slope is tilted towards the left on the coordinate plane.

When two variables have a positive slope, it means that they are positively correlated; that is, when x rises, y rises as well, and when x falls, y falls as well. A line on a line graph that has a positive slope rises as the line advances from left to right.

A line that slopes downward from left to right is said to have a negative slope. In other words, the rise-to-run ratio of the line is negative.

The graph of the two real-life situations is attached with the answer below. In which the equation y = 4x means that the value of y is increasing by 4. Similarly, the equation for negative slope is y = -4x means that the value of y is increasing in opposite direction by factor 4.

The percentage increase in the number of pieces she saws on that day is 40%.

Here it is given that a seamstress sews 55 pieces per day.

But on a certain day, 77 pieces were sewn.

We have to find the percentage increase in the number of pieces she sews on that day.

So first we have to find the increase in the number of pieces she sews.

Increase in the number = 77 - 55

                                       = 22

The original number per day = 55

Formula to find the percentage increase in the number.

Percentage increase = Increase in number/ original number × 100

Now putting the values in the equation:

Percentage increase = 22 / 55 × 100

                                   = 2/5 × 100

                                   = 40%

Therefore there is a 40% increase in the number of pieces.

According to the question,

Perimeter of an isosceles triangle = 37

Length of the base = x

Length of one leg = 4x - 4

As it is an isosceles triangle so length of the other leg will also be 4x - 4.

Perimeter of triangle is equal to sum of all the lengths of the triangle.

[tex] \therefore [/tex]

[tex] \rm \implies Length \: of \: base + Length \: of \: one \: leg + Length \: of \: other \: leg = 37

Answer:

Range:  [tex]\text{y} \ge 0[/tex]

Domain: [tex]\text{x} \ge 0[/tex]

Both involve "greater than or equal to 0".

==============================================

Explanation:

The domain is the set of allowed inputs (x). The smallest input allowed in this case is x = 0, as it corresponds to the left-most point (0,0) on the blue graph. There is no largest x value since it stretches forever to the right.

Either x = 0 or x > 0 which condenses to [tex]\text{x} \ge 0[/tex] and this is the domain as an inequality.

--------

The range will have us look at the possible y values or possible outputs. We have y = 0 as the smallest output possible, which corresponds to the lowest point (0,0).

There is no largest y value since the blue graph goes forever upward.

Either y = 0 or y > 0 to give us the range of [tex]\text{y} \ge 0[/tex]

The equation of the absolute value function graph is: y = |x - 3| + 5.

The equation, y = a|x – h| + k, represents the equation of an absolute value function in the vertex form, where:

We are given the following from the graph:

Vertex (h, k) = (3, 5)

Plug in the values of h and k into the equation, y = a|x – h| + k:

y = a|x - 3| + 5

A point on the graph is (5, 7). Find the value of a by substituting (x, y) = (5, 7) into y = a|x - 3| + 5:

7 = a|5 - 3| + 5

7 = a|2| + 5

7 = 2a + 5

7 - 5 = 2a

2 = 2a

2/2 = 2a/2

1 = a

a = 1

This criterion, known as (alpha) in null hypothesis testing, is often set to 05. The rejection of the null hypothesis is if there is less than a 5% probability that a result as dramatic as the sample result would occur if the null hypothesis is accepted. The outcome is referred to as statistically significant when this occurs.

If a statistical test is run with a threshold of significance = 0.1, 0.05, and 0.01 the null hypothesis was rejected.
