x-intercept: 20

y-intercept: 5

To find the x- and y-intercepts of the graph of the equation x + 4y = 20, we need to solve the equation for x and y, respectively.

First, to find the x-intercept, we need to set y equal to 0 and solve for x. This gives us the following equation:

x + 4(0) = 20

x = 20

Therefore, the x-intercept is (20, 0).

Next, to find the y-intercept, we need to set x equal to 0 and solve for y. This gives us the following equation:

0 + 4y = 20

4y = 20

y = 5

Therefore, the y-intercept is (0, 5).

Answer:

x = 55 degrees, y = 55 degrees

Step-by-step explanation:

1.) Since y and the given angle are Same Side Interior angles, that means that they are supplementary. This means that y + 125 = 180.
2.) By solving this equation, we get y = 55 degrees.

3.) Now, since y and x are corresponding, that means that they equal each other. Therefore, x = 55 degrees.

The side length of the triangle (y) will be 45.88 units.

The Law of Sines The law of trigonometric functions, sine law, sine formula, or sinusoidal rule is a trigonometric equation that relates the sizes of any triangle's edges to the sines of its orientations.

The angle of a triangle is 42° and its opposite side is 31. And the angle of a triangle is 85° and its opposite side is y. Then by the sine law, the equation is written as,

y / sin82° = 31 / sin42°

Estimate: 3

Sum: 2.73

Step-by-step explanation:

To find the estimate, we can round our numbers to the nearest tenth (1.52 would become 1.5, and 1.21 would become 1.2). When we add these two numbers together, we get 2.7, which can be rounded up to 3.

To find the sum, we simply add 1.52 + 1.21, which equals 2.73.

Answer:

y = 6x

Explanation:

This question is asking you to write a linear equation in slope-intercept form, y = mx + b, where m is the slope and b is the y-intercept.

The y-intercept (where the line crosses the y-axis) is visibly 0. As for the slope, you can take two points, I'll use (0,0) and (0.1,0.6) to calculate it.

Slope = y - y/x- x

Slope = (0.6 - 0)/(0.1 - 0) = 0.6/0.1 = 6

Plug in 0 for b and 6 for m and you have an equation.

y = 6x + 0

y = 6x

Answer: y = 6x

Step-by-step explanation: To find the equation you use the form y=mx+b, m is the slope meaning the rise of the function over the run of the function. This function rises 0.6 in terms of y in the time it takes to move or “run” over 0.1 in terms of x. so it would be 6/10 divided by 1/10. which leaves you with 6. b stands for the y-intercept which in this case it crosses the y-axis at zero so it would be zero. so putting it together you would have y=6x

There are two parallel sides and two non-parallel sides to a trapezoid. These are the actual claims:

(A) J is supplementary to K

(E) KL is parallel to JM

In American and Canadian English, a quadrilateral with at least one pair of parallel sides is referred to as a trapezoid.

It is referred to as a trapezium in British and other varieties of English.

In Euclidean geometry, a trapezoid is a convex quadrilateral by definition. The bases of the trapezoid are the parallel sides.

So, a trapezoid's adjacent point angles sum up to 180 degrees.

This implies:

J+K = supplementary angles

L+M = supplementary angles

The highlights mentioned above indicate that J and K are supplemental angles. Thus, (a) is accurate.

A trapezoid also has two parallel sides.

Lines KL and JM must be parallel to one another because they are horizontal.

The highlighted portion above indicates that lines KL and JM are parallel. So, (e) is correct.

Therefore, there are two parallel sides and two non-parallel sides to a trapezoid. These are the actual claims:

(A) J is supplementary to K

The area of a figure is equal to the number of unit squares required to completely cover the surface area of a particular 2-D shape. Square cms, square feet, square inches, square meters, etc. are a few common units for measuring area.

To get the area of the square figures presented below, draw unit squares with 1-centimeter sides. Therefore, the shape will be measured

According to our question-

The velocity in this problem is the average walking speed, hence the distances in the table are calculated by dividing the time in the same row by the velocity.

The velocity is reported as follows for the first row:

2.5 miles per hour is equal to v = 0.5/(12/60) = 0.5/0.2.

The minutes are split by 60 because the time is in hours.

The velocity is stated as follows for the second row:

1.5 x 4/3 divided by 45/60 equals 2 miles per hour, or v.

The velocity is given as follows for the third row:

v = 0.75 x 4 x (15/60) = 4 miles per hour.

Hence, 4 miles per hour.

Also, from the question;

We have the following points

The point is given as

Point = (-4, 6) i.e.  (x, y) = (-4, 6)

The equation of a line can be represented as

y = mx + c

Where

Slope = m

By comparing the equations, we have the following

m = 7

This means that the slope is 7

The slopes of perpendicular lines are opposite reciprocals

This means that the slope of the other line is -1/7

The equation of the line is then calculated as

y = m(x - x₁) +y₁

Where

m = -1/7

(x₁, y₁) = (-4, 6)

So, we have

y = -1/7(x + 4) + 6

The value of x for the given equation is 8.

Logarithm function is defined as the inverse of the exponential function.

If a^(b) = c, then b = log(c) at the base of a.

For negative numbers, the logarithm are complex numbers.

The given equation is as below,

x^(-1/3) = 32x^(-2)

It can be solved as follows,

x^(-1/3) = 32x^(-2)

Take logarithm on both sides to obtain,

log (x^(-1/3)) = log (32x^(-2))

=> -1/3 log(x) = log(32) - 2log(x)

=> 2log(x) - 1/3 log(x) = log(32)

=> 5/3log(x) = log(32)

=> log (x^(5/3)) = log(32)

Remove log from both sides to get,

x^(5/3) = 32

=> x = 32^(3/5)
