true or false? the solutions for y>x+3 are all in the points in the shaded half plane but does not include points on the line y=x+3

Answer:

Explanation:

x-intercept of the linear equation that is parallel to y=-3x-5 and passes through (2, 6) is 4

What is the equation of the line?

The slope of the line and a point on the line can be used to create the equation of a line.

The slope of the line, which can be stated as a numeric integer, fraction, or the tangent of the angle it forms with the positive x-axis, is the line's inclination with respect to the positive x-axis. The coordinate system's point with the x coordinate and the y coordinate is referred to as the point.

Given equation of line is y = -3x - 5

Passing points (a,b) = (2,6)

As we know equation of the line is y = mx + c where m is the slope of the line and c is the y-intercept

On comparing the given equation of the line with y = mx + c , we have slope of the line is -3

Slope of two parallel lines is equal.

Equation of line having slope and passing point is given by y-b = m (x-a)

Therefore, equation of line having slope -3 and passing point (2,6) is y - 6 = -3(x - 2)

⇒ y - 6 = -3x + 6

⇒ y = -3x + 6 + 6

⇒ y = -3x + 12

Equation of line having slope and x-intercept is given by y = m(x - a) where m is the slope and a is the x- intercept

y = -3x + 12 can be written as y = -3(x-4)

On comparing this equation with y = m(x-a) we have x-intercept is 4

Therefore, x-intercept of the linear equation that is parallel to y=-3x-5 and passes through (2, 6) is 4

Mean is 5.25, Median is 5 and mode is 3.

Given,

In the question:

There are numbers:

3, 4, 5, 7, 6, 8, 8, 5, 3, 6, 4, 5, 3, 3, 7, 7.

To find the mean, median and mode.

Let's Know :

How do you find the mean median and mode?

The mean (average) of a data set is found by adding all numbers in the data set and then dividing by the number of values in the set. The median is the middle value when a data set is ordered from least to greatest. The mode is the number that occurs most often in a data set.

Now, According to the above statement :

To find Mean:

[tex]\frac{3+4+ 5+ 7+ 6+ 8+ 8+ 5+ 3+ 6+ 4+ 5+ 3+ 3+ 7+ 7}{16}[/tex]

= 84/16 = 5.25

For Median

Arrange in ascending order

3, 3, 3, 3, 4,4, 5,5,5, 6,6, 7, 7, 7, 8,8.

There is an even no. of observations. i.e., 16 numbers.

then, there is no single middle value; the median is then usually defined to be the mean of the two middle values: so the median of

Middle two values is : (5 + 5)/2 = 10/2 = 5

Middle value is 5

For Mode:

The mode is the number that occurs most often in a data set.

Mode is 3 .

Hence, Mean is 5.25, Median is 5 and mode is 3.

The length of the second shelf is 114 centimetres.

Consider the four shelves as A, B, C and D. According to the question, the length of the four shelves is 2.5 cm.

A + B + C + D = 250 cm ( 1 m = 100 cm ⇒ 2.5 * 100 = 250 ) → 1  

The length of the second shelf is 18 cm longer than twice the length of the first shelf.

B = 2A + 18   →  i

The length of the third shelf is 12 cm shorter than the first shelf.

C = A - 12      →  ii

The length of the fourth shelf is 4 cm longer than the first shelf.

D =  A + 4      →  iii

Substitute i,ii and iii in 1  ⇒  A + B + C + D = 250  

A + 2A + 18 + A - 12 + A + 4 = 250

5A + 22 - 12 = 250

5A + 10 = 250

5A = 250 - 10

5A = 240

A = 240/5

A = 48

Substitute A = 48 in i, ii, iii and then we get,

Angle of depression is 7.7 °  made by the line of sight from the canyon edge to the fire .

The angle of depression is the angle created by the object and the horizontal line as seen from the horizontal line. The distance between two objects is often calculated when the angles and spacing of an object from the ground are known.

let f be the the fire

b is the base of the sheer canyon wall

o be the cliffs of insanity point that is canyon edge

so OB = 7117 Feet

bf = 10 miles = 10 * 5280 = 52800 feet

angle of depression is < xof which is equal to < ofb

let the angle of depression is [tex]\theta[/tex]

now from triangle obf ; it is a right angle triangle , where of = hypotenuse

bf = base , ob = height < ofb = [tex]\theta[/tex]

so , tan [tex]\theta[/tex] = ob/bf = 7117/52800

[tex]\theta[/tex] = [tex]tan^{-1}[/tex] ( 7117/52800) = 7.68 ° = 7.7 °

y-6 = -5/3 (x+2) is the point - slope equation of the line through (-2 , 6 ) ( 1 , 1 ) using exact numbers.

For linear equations, the typical form is y-y1=m(x-x1). It highlights the line's slope and a line point (that is not the y-intercept).

The two approaches for determining the equation of a line given a point and its slope are as follows:

(a). Input the slope and the (x, y) point values into the equation y = mx + b, then solve for b using the substitution technique

b) Point-slope form: (x 1, y 1), where (y 1, x 1) is the point and (m, the slope) is the specified slope.

First you need to find the slope, (y2-y1)/(x2-x1).  This is (1-6)/(1-(-2)) or -5/3

Now that you know the slope you can use that for the point-slope equation

The point-slope equation is y-y1 = m(x-x1).  If we start with y-6, the x value is -2 (from our point (-2,6)

     y-6 = -5/3 (x-(-2))

or, y-6 = -5/3 (x+2)

When two expressions are connected with the equals sign (=) in a mathematical formula, it expresses the equality of the two expressions. An equation is an algebraic statement that demonstrates two mathematical expressions are equivalent in algebra, and this is how it is most usually used. In the equation 3x + 5 = 14, for instance, the two expressions 3x + 5 and 14 are separated by the symbol "equal." When two expressions are joined by an equal sign, a mathematical statement is called an equation. An equation is something like 3x - 5 = 16. By solving for x, we discover that x equals 7, which is the value for the variable.

(1) The sum of the given expressions is given as
