The function for the points are  y = -15x - 5

From the information given, we have that;

The points are;

(1/3,0) (-2 3/4,0) and (0,-5)

Using the point-slope form of a linear equation, we have;

y - y₁ = m(x - x₁)

Such that;

Using (1/3, 0) and (0, -5), we have that the slope is;

m = (0 - (-5))/0 -1/3)

expand the bracket

= 5 / (-1/3)

= -15

Now, take any of the given points and substitute the values

Using (1/3, 0), we get;

y - 0 = -15(x - 1/3).

y = -15x - 5.

The function for the points solved by  (1/3,0) (-2 3/4,0) and (0,-5) solved by point slope form is \(a=-15b-5\)

We have given the points:

(1/3,0) (-2 3/4,0) and (0,-5)

Using the formula of linear equation

\(a-\)\(a_{1}\)\(=x[b-b_{1}]\)                                                          

Where we will consider (1/3,0) = \(a-a_{1}\) and (0,-5) = \(b-b_{1}\)

that is 1/3 = \(a\), 0 = \(a_{1}\) and

0 = \(b\), -5 = \(b_{1}\)

\(x\) refers to the slope of line (take any variable)

Now for finding the value of \(x\),

\(x=a-a_{1}/b-b_{1}\)

inserting the values,

\(x=[0-[-5]]/[0-1/3]\\x= -15\)

Substitute the value of \(x\) in the equation

\(a-0=-15[b-1/3]\)

By simplifying the equation, we get

\(a=-15b-5\)

4^2 is 16, since 4 * 4 = 16

Now the equation is 24 - 16 + 2*2

2 * 2 = 4

24 - 16 + 4

24 - 16 = 8

8 + 4 = 12

Answer is 25 degrees.

Answer:

k=12

Step-by-step explanation:

Top left angle is 84 degrees also, due to alternate interior angles cut by the transveral.

2 sides are congruent, leaving bottom left corner angle also 84 degrees.

Write an equation to solve for k:

84+84+k=180

simplify

168+k=180

subtract 168 from both sides

k=12

Answer:

1 square for every 4 circles

1:4

1/4

Step-by-step explanation:

To get it to the simplest ratio all you have to do is put the given numbers (8,2) into fraction form based on the order given in the question. The order given was "squares to circles". This makes squares the numerator and circles the denominator. After you set it into a fraction just reduce the fraction to its simplest form.

Answer:

2/13

Step-by-step explanation:

To find a fraction of a fraction, you just multiply the two.

So 22/39 x 3/11 is 22x39 over 3/11

or 66/429.

Simplified would be 22/39.

The value of 22 / 39 of 3 / 11 on simplification is 6 / 39.

The fundamental concept of making the same number of additions repeatedly is represented by the action of multiplication. The results of multiplying two or more integers are known as the products, and the factors that are used in the multiplication are referred to as the factors.

Given:

22 / 39 of 3 / 11

As we know of means multiplication then,

22 / 39 × 3 / 11

(22 × 3) / (39 × 11)

66 / 429

This can be simplified as,

6 / 39

The distance between Orlando and Jacksonville is 140 miles, So Option C is correct

Distance is a numerical measurement of how far apart two or more points are in space, typically in one, two, or three dimensions. It is used to describe the separation between objects, locations, or events.

Given that,

Two places name,

Orlando,

And Jacksonville

The distance between them in miles = ?

So, the distance between two places in kilometers,

\(\implies 201.24 \ \text{km}\)

It is known that,

\(\text{1 km = 0.621371 miles}\)

So that,

\(\text{201.24 km} = 201.24 \times\text{0.621371 miles}\)

                   \(= \text{125.04470004 miles}\)

In the options, 140 is nearest of 125

Hence, the distance between both the places is 140 miles.

We know that each large tree costs $4.50, and each small tree costs $2.25. If you buy 4 large trees, that means you will spend 4 * $4.50 = $<<4*4.5=18>>18 on large trees.

If you can spend a total of $50, then you have $50 - $18 = $<<50-18=32>>32 to spend on small trees.

The total cost of the small trees will be s * $2.25, where s is the number of small trees you buy.

To find the maximum number of small trees you can buy, we can set this expression equal to $32 and solve for s:

s * $2.25 = $32

s = $32 / $2.25

s = 14.22

Since you can't buy a fraction of a tree, the maximum number of small trees you can buy is 14.

Answer:

If each large tree costs 4.50 and you need to buy 4, then 4 x 4.50 = $18.00 leaving you with $32.00. With these 32 dollars left, you can now buy 14 small trees, still being left with a remainder of 0.50$.
