What is the value of x in this triangle?
to
44°
53°

Answer:

No

Step-by-step explanation:

Notice when x increases by 1, y increases by $6?

When x goes from 1.5 to 2.5 gigabytes ( increase by 1 ), y increases from $65 to $71. That's a $6 increase for x increasing by 1 gigabyte.

In addition, when x goes from 2.5 to 3.5 gigabytes ( increase by 1), y increases from $71 to $77. This is also a $6 increase for x increasing by 1 gigabyte.

Yet...

65 / 1.5 doesn't equal 71 / 2.5

65 / 1.5 = 43 1/3

71 / 2.5 = 28.4

43 1/3 [tex]\neq[/tex] 28.4, so there is no proportion

Answer: No.

Step-by-step explanation:

      In a proportion relationship, y = kx. In other words, x times the constant of proportionality will equal y. Without a given constant of proportionality, we can use k =[tex]\frac{y}{x}[/tex]. In all instances, y divided by x should equal the same value (k). We will see if this stands true for all the given values.

      65 / 1.5 = 43.33333

      71 / 2.5 = 28.4

      74 / 3 = 24.66667

      77 / 3.5 = 22

      No. The x and y values do not have a proportional relationship.

Answer:

11,000 or to be more specific $11,000

Step-by-step explanation:

Well there is no equation provided so one has to go by the graph

The y-intercept is where the line intersects the y-axis

Looking at the graph we see this is at y ≅ 11,000

Of course it all depends on your best fit line that you have drawn though it looks OK

Basically the y-intercept for this graph is $11,000 which is the cost of the Prius in 2004

Y form is the slope-intercept form of a straight line.

Here, x and y are the coordinates of the points, m is the gradient, and b is the intercept of the y-axis.

y = mx + b is the slope-intercept form of the equation of a straight line. In the equation y = mx + b, m is the slope of the line and b is the intercept.

The value of b is equal to y when x = 0, and m shows how steep the line is. The slope of the line is also called the gradient.

To find the equation of the straight line, we use the slope-intercept form, y = mx + b, where m is the slope of the line, b is the y-intercept of the line.

We can find the equation of a line in the form of y = mx + b, if the coordinates of points forming the line are known to us.

Thus, Y form is the slope-intercept form of a straight line.

Step-by-step explanation:

x^4 - 10x^2 + 9 = 0

Step 1

Let t = x^2

So , we have the quadratic

t^2 - 10t + 9 = 0

Step 2

Factorise:

(t - 1)(t - 9) = 0

Step 3

So, t - 1 = 0 or t - 9 = 0

t = 1, 9.

But t = x^2

So, we have x^2 = 1 or x^2 = 9

26 skittles are not red

Explenation:

35%of 40 is 14 because 40*0.35=14 red skittles

total number of skittles (40)-red skittles (14)=26

Answer:

26 skittles are not red

Step-by-step explanation:

Simplify the percentage.

35% = 35/100 = 0.35

Multiply 40 by 0.35.

40 x 0.35 = 14 (This is how many skittles are red.)

Now subtract the red skittles from the packet.

40 - 14 = 26

Hence, there are 26 skittles that are not red, and 14 skittles that are red.

The value of exponential growth  after 327 minutes is 1870.

Exponential growth is the process by which quantity increases over time. It occurs when a quantity's instantaneous rate of change with respect to time is proportional to the quantity itself.

An exponential function depicts the relationship between an input and an output by using repeated multiplication on an initial value to obtain the output for any given input.

We are aware that

The exponential growth equation is equal to

y = a(1 + r)ˣ

where

an is the starting point.

r denotes the growth rate.

x represents the time in hours.

y is the quantity's value.

We now have

a = 1800

r = 0.7%

 = 0.7/100

 = 0.007

By substituting,

y = 1800(1 + 0.007)ˣ

The other equation of the system of linear equation that has no solution is y = 2x - 2.

If a system of linear equations has no solution, it means that the equations are inconsistent, which means that the two lines represented by the equations will not intersect. Therefore, the lines are parallel with each other.

One way to find the equation of the other line that would make the system inconsistent is to find the equation of a line that is parallel to the given equation but has a different y-intercept.

The given equation is in slope-intercept form, y = mx + b, where m is the slope (in this case, m = 2) and b is the y-intercept (in this case, b = -1).

A line that is parallel to the given line will have the same slope (m = 2), but a different y-intercept. For example, a line with y-intercept of -2: y = 2x - 2.

The law of Sines is used to find the length of the third side of an obtuse triangle. The value of a i.e., third side length is equals to 6.065 units.

In geometry, obtuse triangles are defined as the triangles with an obtuse angle, which is an angle measuring greater than 90°. According to the law of sines of triangles if a triangle has sides a, b, and c, and angles A, B, and C, where side a has opposite angle A, side b has opposite angle B, and c has opposite angle C, then

sinA/a = sinB/b = sinC/c

The sum of all interior angles of a triangle is 180°. If we have two of the sides of an obtuse triangle, and two of the angles of an obtuse triangle, then we can use the law of sines to determine the third side of the obtuse triangle. Let's consider an obtuse triangle ABC present in above figure. We want to find the length of side a. We have, AB = 8 units , AC = 5 units, BC = a units.

∠A = 32° , ∠B =40° , ∠C = obtuse angle

=>∠C = 180°-∠A - ∠B = 180°- 32°- 40° = 108°

From above formula, sinA/a = sinB/b= sinC/c

=> sin 32°/5 = sin 40°/a = sin 108°/8

=> a = 5 sin 40°/ sin 32°

=> a = 5×0.6428/0.5299

=> a = 6.06529533874

=> a ≈ 6.065

Jacob went into the same movie theater and bought 5 bags of popcorn and 4 drinks, costing a total of $51.50. This will be:

5p + 4d = 51.50

where P = popcorn

d = drink

The equations will be:

9p + 8d = 97.50

5p + 4d = 51.50

Multiply equation i by 5

Multiply equation ii by 9

45p + 36d = 463.50

Subtract

4d = 24

Divide.

d = 24/4

d = 6

Since 9p + 8d = 97.50

9p + 8(6) = 97.50

9p + 48 = 97.50

A square yard of carpet that is selling for $8.95 per square foot would cost $80.55 per square yard.

What is the conversion factor?

A conversion factor is a number used to change one set of units to another, by multiplying or dividing. When a conversion is necessary, the appropriate conversion factor to an equal value must be used. For example, to convert inches to feet, the appropriate conversion value is 12 inches equals 1 foot.

A square yard of carpet is equivalent to 9 square feet because 1 yard = 3 feet and 1 square foot = 1 foot x 1 foot.

So, to find the cost of a square yard of carpet that is selling for $8.95 per square foot, we need to multiply the price per square foot by the conversion factor of 9 square feet per square yard.

$8.95/square foot * 9 square feet/square yard = $80.55/square yard

Answer:

Below

Step-by-step explanation:

The point-slope form of a line is:

y - y1 = m(x - x1)

Where m is the slope of the line and (x1, y1) is a point on the line.

Given that the line contains the point (-2, 1) we know that this point is on the line, so we can use it as (x1, y1) in the point-slope form.

By using the point (-2,1) we can write the point-slope form of the line as:

y - 1 = m(x + 2)

This means that the point-slope form of a line with slope that contains the point (-2, 1) is y - 1 = m(x + 2) where m is the slope of the line.
