(-2)(7)(-75)(3)(-2)=?

Answer:

B E F G

Step-by-step explanation:

Polygons are 2 dimensional shapes with straight edges (no curved edges). The shape needs to be closed up entirely to be a polygon. It cannot have any intersecting line segments

A can't be a polygon because the shape isn't closed up entirely

C can't be a polygon because it is a 3d shape

D can't be a polygon because it has curved edges.

H can't be a polygon because it isn't closed up (there are no line segments).

I can't be a polygon because polygons cannot have intersecting lines

J can't be a polygon because polygons cannot have intersecting lines

I hope this helps! If it does, a rate or brainliest would be much appreciated. :)

Answer: Substitution

Step-by-step explanation:

GIVEN:

y=3x

2x+4y=12

Then, 2x+4(3x)=12

-----------------------------------------

Substitution: replacing one variable in terms of another variable.

As we can see from the given aspects, y=3x, and the conclusion expression has no y instead of 3x. This means it represented y in terms of x, which fits the definition of substitution that replaces one variable.

Hope this helps!! :)

Answer: x = 2y

Step-by-step explanation:

Let's solve for x.

2(3x+4y)=4x+12y

Step 1: Add -4x to both sides.

6x+8y+−4x=4x+12y+−4x

2x+8y=12y

Step 2: Add -8y to both sides.

2x+8y+−8y=12y+−8y

2x=4y

Step 3: Divide both sides by 2.

2x

2

=

4y

2

x=2y

Answer:

x=2y

Solve for x

2 ( 3x + 4y ) = 4x + 12y

6x + 8y = 4x + 12y

6x + 8y - 4x = 12y

2x + 8y = 12y

2x = 12y - 8y

2x = 4y

2x / 2 = 4y / 2

x = 4y / 2

x = 2y

Answer:

B. 1.8miles/hour

Step-by-step explanation:

Speed = distance/time

Given parameters

Distance = 3/10 miles

Time = 10miuntes

Convert the time to hours

10minutes = (10/60)hour

10minutes = 1/6 hour

Substitute the parameters into the formula;

Distance = (3/10)/(1/6)

Distance = 3/10× 6/1

Distance = 18/10

DISTANCE = 1.8miles/hour

g(x) = -|x|

Step-by-step explanation:

f(x) = |x|

y = −f(x)  Reflects it about x-axis

g(x) = -|x|

We start off with: f(x) = |x|

Reflection across x-axis

y = -f(x)

After: g(x) = -|x|

87, median is the middle value

Step-by-step explanation:

put them in order from least to greatest

56, 72, 87, 89, 93

87 is your median

Answer:

The median of her scores is 87

Step-by-step explanation:

What is median?

The middle number; found by ordering all data points and picking out the one in the middle (or if there are two middle numbers, taking the mean of those two numbers) is called a median.

Arranging the data in ascending order.

56,72,87,89,93.

n=5

Median =[(n+1)/2]th observation.

            =[(5+1)/2]th observation

           =3rd observation

          = 87

Hence, the answer is Option (B) 87

Step-by-step explanation:

2x - 3 = - x + 3

First, combine the like terms

(Don't forget to change the signs with you bring a number or variable from one side to another.)

2x + x = 3 + 3

Then, add or subtract.

Answer:

2x+2y+z

Step-by-step explanation:

Step-by-step explanation:

y + 65°= 180° (Being co-interior angle)

y = 180° - 65°

y = 115°

Next we will find of the next co-interior angle which is A and D

(2x - 10)° + (3x + 20)° = 180° ( Same reason)

Now we will keep the like ones together.

2x° + 3x° - 10° + 20° = 180°

5x° + 10° = 180°

5x = 180° - 10°

5x = 170°

x = 170°/5

x = 34°

Now we need to find (2x - 10)° and (3x + 20)°

(2x - 10)°

=(2×34-10)°

=(68-10)°

=58°

(3x + 20)°

=(3×34-20)°

=(102-10)°

=92°

16.93 units

Step-by-step explanation:

Length of a segment having extreme ends [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] is given by the formula,

d = [tex]\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

ML = [tex]\sqrt{(4-1)^2+(0-4)^2}[/tex]

     = 5 units

LP = [tex]\sqrt{(1+1)^2+(4+2)^2}[/tex]

    = [tex]\sqrt{40}[/tex] ≈ 6.32 units

PN = [tex]\sqrt{(-1-2)^2+(-2-0)^2}[/tex]

     = [tex]\sqrt{13}[/tex]

     ≈ 3.61 units

NM = [tex]\sqrt{(4-2)^2+(0)^2}[/tex]

      = 2 units

Perimeter of the polygon MLPN = ML + LP + PN + NM

                                                     = 5 + 6.32 + 3.61 + 2

-150 is closer to the number 0 than -250 or 300. :D

Answer:

Step-by-step explanation:

In this problem, we are to model the equation for the total cost of producing a phone

Given that the fixed cost is $600

Also, the total cost of producing 4 phones in a day is $1600

hence the cost of producing 1 phone would be 1600/4= $400

the equation for producing p phones would be

C= 400P+ 600

This equation is the same as the equation of a straight line Y=mx+c

with C=y

400= m= gradient

P=x, the dependent variable

600= c the constant term.

Answer:

c=250+600

Step-by-step explanation:

The number 4.5x10⁻⁶ can be expressed in standard notation as decimal 0.0000045.

In scientific notation, numbers are expressed as a decimal number between 1 and 10 multiplied by a power of 10. In this case, 4.5 is the decimal number and 10⁻⁶ represents the power of 10.

To convert this to standard notation, we move the decimal point six places to the left to match the negative exponent of 10⁻⁶. This gives us:

0.0000045

In standard notation, this number is written as 0.0000045, where the zeros after the decimal point indicate the value of the number in the place of each digit. The last non-zero digit in this case is 5, which is in the sixth decimal place.
