Equation of the line is y = -3x + 7.

Two lines in the same plane that are equally spaced apart and never cross each other are said to be parallel lines.

Suppose the line's equation is y=mx + c, where m and c are unknowns.

Since it is parallel to the equation y = -3x + 4 and -3x - y = -4, its slope is now -3. So m = -3.

Additionally, point  (1,4). Therefore, this should be satisfied by our line's equation.

Consequently, 4 = -3(1) + c

therefore c = 7

The total number of lay-ups in 14 baskets is 10

In fourteen baskets

From the question, we have the following parameters that can be used in our computation:

Lay-ups = 5 out of 7 baskets

This means that

Lay-ups = 5/7 baskets

When the number of baskets is 14, we have

Lay-ups = 5/7 * 14

Evaluate

Lay-ups = 10

In one hundred forty baskets

From the question, we have the following parameters that can be used in our computation:

Lay-ups = 5 out of 7 baskets

This means that

Lay-ups = 5/7 baskets

When the number of baskets is 140, we have

Lay-ups = 5/7 * 140

Evaluate

Lay-ups = 100

Step-by-step explanation:

area of Triangle: ½ × height × base = ½ ×6×6= 18 cm

area of Rectangle: length × width= 6×9 = 54 cm

area of circle= π × (radius)² then...

area of Half-circle = [π×(radius)²] ÷2 = [3.14×(6/2)²] ÷2 = 14.13 cm

The Area of this figure= 18 + 54 + 14.13 = 86.13 cm

Answer:

[tex]A = 86.13[/tex]

Step-by-step explanation:

In order to find the area of the given figure

We need to divide the figure Into the following shapes

Firstly,

A triangle

Rectangle

Semi Circle

Area of a triangle + Area of a rectangle +  Area of a semi circle = Area of the whole figure

So lets find the area of the figures

Area of Triangle = [tex]\frac{1}{2}[/tex]X[tex]6[/tex]X[tex]6[/tex]

= [tex]18[/tex]

Area of a rectangle = [tex]l[/tex]x[tex]b[/tex]

A line with a slope of 2 and a point at (4,3) satisfies the equation y = 2x - 5.

Two expressions joined by an equal sign form a mathematical statement known as an equation. An equation is, for instance, 3x - 5 = 16. We can solve this equation and determine that the value of the variable x is 7.

In general, a straight line has the equation y = mx + c, where m denotes the gradient and y = c denotes the point at which the line intersects the y-axis. do s s., s. s s.. s... s.. A straight line with a gradient of m and an intercept of c on the y-axis has the equation y = mx + c.

Here,

given: slope of 2/3

Step-by-step explanation:

The new coordinates of each of the triangle coordinates are;

1) A'(-12, 6), B'(3, 9), C'(-9, 18)

2) A'(-2, 1), B'(1/2, 3/2), C'(-3/2, 3)

An equation is a mathematical statement that shows that two expressions are equal. An equation typically consists of two sides, with an equals sign (=) in between.

A linear equation is an equation in which the highest power of the variable is 1. In other words, a linear equation is an equation that can be written in the form:

ax + b = 0

where a and b are constants and x is the variable.

To find out how many employees attended the party, you can set up the following equation:

Number of employees * $30 per employee = $1000 for space + $850 for food + $250 for decorations

You can then solve for the number of employees by dividing both sides of the equation by $30 per employee:

Number of employees = ($1000 for space + $850 for food + $250 for decorations) / $30 per employee

A standard deviation (or) is a measure of how widely distributed the data is in reference to the mean. A low standard deviation suggests that data is grouped around the mean, whereas a large standard deviation shows that data is more spread out. Statisticians have concluded that numbers with a margin of error of no more than 2 SD reflect measures that are closer to the real value than those with a margin of error more than 2SD. As a result, most QC procedures mandate that remedial action be taken for data points that consistently fall outside of the 2SD range.

g(n) = 13 + .75n

We want to find where f(n) < g(n):

20.50 < 13 + .75n → subtract 13

From the question, we have the following parameters that can be used in our computation:

Function: S(d) = 86log d + 112

Express the above function properly

So, we have the following representation

S(d) = 86log(d) + 112

From the question, we have:

Distance = 50th mile.

This means that

d = 50

Substitute the known values in the above equation, so, we have the following representation

S(50) = 86log(50) + 112

Evaluate the logarithm

So, we have the following representation

S(50) = 86 * 1.699 + 112

Evaluate the products

S(50) = 146.114 + 112

The rate of change of the height of the top of the ladder above the ground at the instant when the base of the ladder is 30 ft. from the base of the building is -3 ft./min.

The rate of change of the height of the top of the ladder above the ground at the instant when the base of the ladder is 30 ft. from the base of the building is -3 ft./min. This rate takes into account the fact that the ladder is slipping at a rate of 3 ft./min. As the base of the ladder is slipping away from the building, the top of the ladder is moving down, hence the negative rate of change. This rate of change will remain the same until the base of the ladder has slipped the full 50 ft. from the base of the building. At this point, the rate of the change of the height of the top of the ladder will be 0, since the ladder will no longer be slipping.

The rate of change can be calculated as follows:

Rate of change = Change in height / Change in time

Change in height = Initial height - Final height

Initial height = 50 ft.

Final height = 50 ft. - 30 ft. = 20 ft.

Change in time = 30 ft. / 3 ft./min. = 10 min.

Rate of change = (50 ft. - 20 ft.) / 10 min. = -3 ft./min.

Let x be the number of miles the driver still has to travel.

The driver traveled 120 + 120/4 + 120/42/3 = 120 + 30 + 40 = 190 miles.

So the remaining distance is x + 190 = 55 + 1 2/3 * x

Multiplying both sides by 3/2 gives 3/2x + 3/2190 = 3/255 + 3/2*x + x

This simplifies to x = 190.

Therefore, the driver still has to travel 190 miles.
