The slope intercept form is y = 1/4x + 13/4

The general expression for slope intercept form is given as follows

                 y = mx + c

        where, m = slope of the line

                       c = intercept

We have been given the equation that is,

         y – 2 = 1/4(x+ 5)

We will solve this step by step to convert it into the general form that is,

       y – 2 = 1/4(x+ 5)

       y – 2 = 1/4x + 5/4

          y = 1/4x + 5/4 + 2

          y = 1/4x +13/4

which is in the general form of   y= mx + c where m = 1/4 and c = 13/4

Answer:

m1 = 122°

m2= 58°

Step-by-step explanation:

M1 is an alternate interior angle, of 122°, which means that that angle is also 122°.

The line with m1 and m2 added together equal 180°, so we can subtract 122 from 180 to find m2.

180-122= 58

The point P which partitions the line segment AB have coordinates as P(0,3)

Line Segment is a line which joins together two points to form a straight line. It can be extended in either side.

It is given that,

A line segment AB having coordinates such as A(0,0) and B(0,6) respectively

The line segment AB is partitioned by a given point P in two minor line segments AP and PB

We need to find, the coordinates of the partitioning point i.e. P

The given formula will be used,

The coordinates of the point P = ([tex]\frac{x1+x2}{2}[/tex], [tex]\frac{y1 + y2}{2}[/tex])

Now, x1 = 0, x2 = 0, y1 = 0, y2 = 6

Putting values in the formula, we get

([tex]\frac{0+0}{2}[/tex], [tex]\frac{0+6}{2}[/tex])

(0,3)

Hence, the point P which partitions the line segment AB have coordinates as P(0,3)

The first five terms of the sequence an =5 n-3 are 2, 7, 12, 17  and 22.

According to the question.

We have a formula or a rule for finding the terms of a sequence i.e.

an = 5n -3.

The first term of the sequnence an = 5n - 3 is given by

a(1) = 5(1) -3 = 5 -3 = 2

The second term of the sequence an = 5n - 3 is given by

a(2) = 5(2) - 3 = 10 - 3 = 7

The third term of the sequence an = 5n -3 is given by

a(3) = 5(3) - 3 = 15 - 3 = 12

The fourth term of the sequence an = 5n - 3 is given by

a(4) = 5(4) - 3 = 20 - 3 = 17

The fifth term of the sequence an = 5n - 3 is given by

a(5) =  5(5) - 3 = 25 - 3 = 22

Hence, the first five terms of the sequence an =5 n-3 are 2, 7, 12, 17  and 22.

The standard deviation is 7.35.

Standard deviation is used to determine how the values in a group differs from the mean of the values in the group

In order to determine the standard deviation, take the following steps:

Determine the mean of the observation: (87 + 91 + 74 + 73 + 80 + 84 + 68 + 75) / 8 =79

Determine the difference between each value and the mean and then square the result:

(87 - 79)² + ( 91 - 79) ² + (74 - 79)² + (73 - 79)² + (80 - 79)²  + (84- 79)²  + (68 - 79)²  +( 75- 79) ²

64 + 144 + 25 + 36 + 1 + 25 + 121 + 16 = 432

The statement, m∠A ≅ m∠B, represents the congruence property.

The congruency property of equality states that if two angles have measures that are equal to each other, then both angles are said to be congruent to each other.

Given that:

The measure of angle A = 29 degrees

The measure of angle B = 29 degrees.

Since both angles have the same measure, then both angles are congruent to each other.

Answer:

The value of the given series is 49.75

Step-by-step explanation:

This is a problem from geometric progression ,

As we know the formula for geometric progression is aₙ = a₁ r ⁿ⁻¹

Where , a₁ is the first term and r is the ratio , and n is the number of terms.

Ratio is , 40/80 = 1/2

Here , a₄ = 80 . (1/2)⁴ ⁻ ¹ = 80 / 8  = 10

a₅ = 80 . (1/2)⁵ ⁻ ¹ = 80 / 16 = 0.5

a₆ = 80 . (1/2)⁶ ⁻ ¹ = 0.25

a₇ = 80 . (1/2)⁷ - ¹ = 0.125

a₈ = 80 . (1/2) ⁸ ⁻ ¹ = 0.625

If AB = 6y - 14, BC = 10 - 2y then the value of AC = 8.

In geometry, the midpoint is the point in the middle of a line segment. It is equidistant from both endpoints and serves as the segment and endpoint centroid. It cuts the segment in half.

Given: AB = 6y - 14, BC = 10 - 2y

Since B is the midpoint of AC, AB = BC then

6y - 14 = 10 - 2y

Add 14 on both sides of the equation, and we get

6y - 14 + 14 = 10 - 2y + 14

6y = - 2y + 24

Add 2y on both sides of the equation

6y + 2y = - 2y + 24 + 2y

simplifying the above equation, we get

8y = 24

y = 24/8

y = 3

Substitute the value of y in AC then we get

AC = 2(6(3) - 14)

= 2(4)

AC = 8

Therefore, the value of AC = 8.
