Answer:

[tex]2\sqrt{34}[/tex] ≈ 11.6619

Step-by-step explanation:

Answer: 6 units Step-by-step explanation: Use the distance formula, [tex]\sqrt{(x_{2}-x_{1})^{2}+(y_{2}-y_{1})^{2}}[/tex]. Plug the x and y values from the given points into the distance formula:

[tex]\sqrt{(7-[-3])^{2}+(4-[-2])^{2}}[/tex]

Simplify:

[tex]2\sqrt{34}[/tex] ≈ 11.6619

Thank you!

The distance between two coordinate points is 11.66 units.

The distance formula which is used to find the distance between two points in a two-dimensional plane is also known as the Euclidean distance formula. On 2D plane the distance between two points (x₁, y₁) and (x₂, y₂) is Distance = √[(x₂-x₁)²+(y₂-y₁)²].

The given coordinate points are (-3, -2) and (7, 4)

Substitute (x₁, y₁) =(-3, -2) and (x₂, y₂)=(7, 4) in distance formula, we get

Distance = √[(7+3)²+(4+2)²]

= √(100+36)

= √136

= 11.66 units

Therefore, the distance between two coordinate points is 11.66 units.

Answer:

x≤-8

Step-by-step explanation:

Answer:

x ≤ -8

Step-by-step explanation:

Good Luck!

Answer:

m<1 = 125°

m<2 = 55°

Step-by-step explanation:

Okay, so we're dealing with alternate interior angles and all that sorta stuff, so I'll try to explain it best I can, if I'm too confusing let me know, let's go:

So the angle labeled 125° and angle 1 are alternate interior angles, so they're equal (yes, we're ignoring the fact that that might not me right because the other line isn't straight, I don't have another solution okay) anyways, so that means that:

1 = 125°

Now we know what 1 and 2 are on the same plane or axis or something like that, so basically, 1 and 2 HAVE TO add up to 180°, so that means that:

125 + x = 180

And now we just have to do the inverse operations thing:

180 - 125 = 55

So, m<1 = 125° and m<2 = 55°

tell me if this is wrong so I can fix it

hope this helps:)

Answer:

[tex]x = \frac{1}{4}[/tex]

Step-by-step explanation:

Step 1: Subtract [tex]\frac{3}{4}[/tex] from 1

[tex]1 - \frac{3}{4}\\\\= \frac{1}{4}[/tex]

Therefore, the point could be [tex]\frac{1}{4}[/tex]

Answer:

Answers are: 2x - 7, and 2x -7 = 14

Step-by-step explanation:

An expression must have variables must have a coefficient, a number that is multiplied divided added or subtracted by our variable. The variable is a place holder.

So our answers would be 2x - 7, and 2x -7 = 14

is the ratio .he she and shd

Answer:

3.5944

Step-by-step explanation:

first the fraction is mixed and you need to change the fraction to proper or improper fraction

the denominator 4 is multiply 16

16×4=64

then the numerator 3 is add to 64

64+3=67

the fraction will be

=====67/4

the denominator is not change from the first part

》》do the same thing by the other mixed fraction

the final answer would be 3.5944

first calculate 67÷4=16.75

the second calculate 14÷3=4.66

in the second part i get 14/3 that means i change the mixed fraction to the normal fraction

calculate 16.75÷4.66=3.5944

Answer:

$250

Step-by-step explanation:

The formula for simple interest is I = PRT, where I= interest earned or paid, P = principal deposited or borrowed, R = interest rate as a decimal, and T = time in years.

I = PRT

I = (1000)(0.05)(5)

I = 250

Answer:

See explanation.

Step-by-step explanation:

You will need to know the abbreviations of measurements because when pertaining to the real world, an you will see things as so "This fence is about 15ft tall." or "Jacobb is 72in tall."  If you do not understand the abbreviations you will not understand what anyone is ever talking about when it comes to measurements. As for knowing how to convert measures to be equivalent, that is important because some measurements are bigger than others. It doesn't make since to say 12 inches, when you can just say 1 foot.

Answer:

x=2

Step-by-step explanation:

The solution is, The equation the line is, x =2

A straight line is an endless one-dimensional figure that has no width. It is a combination of endless points joined both sides of a point and has no curve.

Here, we have to points (2,4) and, (2,-7)

So, by using the formula of equation of straight line of two-point form, we get,

(y-y_1)/(x-x_1 )=(y_2-y_1)/(x_2-x_1 )

=>(y-4)/(x-2)=(-7-4)/(2-2)

=>0 = x-2

=>x =2

Hence, the required equation is,  x =2

8x7=56, so 56 students can sit at a table, 58-56=2 students without a table.

Your answer would be 2.

Answer:

2 students cannot sit down at tables.

Step-by-step explanation:

Since there are a total of 58 students and only 7 tables and each table can only fit 8 students, you'll need to calculate how many students can sit at 7 tables first:

7(8) = 56 So, with 8 students sitting at all 7 tables, there are 56 students that can sit at a table.

To find how many students can't sit at a table you'll have to subtract 56 from 58,

58-56 = 2 So, 2 students will not be able to sit down at tables.

Answer: y= 2x+3; y=-1/3x+3

Step-by-step explanation:

First option on edge

y = 2x + 3 and y = -(1/3)x + 3 define the function graphed below.

The correct option is 1.

Graph, a visual depiction of statistical information or a relationship between variables that serves a purpose. Graphs serve a predictive purpose because they have the advantage of displaying broad trends in the quantitative behavior of data. But, as just approximations, they may be imprecise and occasionally deceptive. The majority of graphs include two axes: a horizontal axis that represents a set of independent variables and a vertical axis that represents a set of dependent variables. A broken-line graph, in which time is typically the independent variable, is the most typical type of graph.

The graph of the functions and the points on the line is given.

The points for 1st function = (0, 3)

The points for 2nd function = (3, 2)

The given function:

y = 2x + 3

Substituting (0, 3)

3 = 2(0) + 3

3 = 3

Similarly, for y = -(1/3)x + 3

Substituting (3, 2)

2 = -(3/3) + 3

2 = -1 + 3

2 = 2

Hence, y = 2x + 3 and y = -(1/3)x + 3 define the function graphed below.
