Answer:

10

Step-by-step explanation:

N(-2,1), P(3,1), Q(3, -1), R(-2, -1)

The polygon is the rectangle with sides 2 and 5

So the area is 2*5 = 10

see attached

Answer:

1) 2m + 3m2 - 4m=7

7) 3m2 – 2m + 4m= 11

8) 20 + 109 + 39 - 4= 164

3) 2m + 4m - 3m2= -3

9) 4xy + x + 2xy= 0

4) 2y + 14x - 7x + 9y= 18

10) 6m2 - 6m - 9m2= -51

Step-by-step explanation:

Let's try some integer values of x to see what volumes we get

We do not get 15 as a result in that list above. So there are no integer solutions to x^3 = 15

In other words, the value [tex]\sqrt[3]{15}[/tex] is not an integer.

Answer:

a) the multiplier is the years

b) cost of iPhone = 600 + 600* (.1x)

c) f(3) = $780

d) f(-2) = 480

Answer:

Step-by-step explanation:

Given the points R(-4, 5) and S(2, -1), to get the distance between the points, we will use the formula;

D = √(x2-x1)²+(y2-y1)²

Given x1= -4, y1 = 5, x2 = 2 and y2 = -1

RS = √(2-(-4))²+(-1-5)²

RS = √(6)²+(-6)²

RS = √36+36

RS = √72

RS = √2×36

RS = 6√2units

To get the midpoint, we will use the formula M(X,Y) = (x1+x2/2, y1+y2/2)

(X,Y) = (-4+2/2, -1+5/2)

(X,Y) = (-2/2, 4/2)

(X,Y) = (-1,2)

Hence the midpoint is (-1,2)

To get a point P 1/3 of the distance of RS, we will multiply 1/3 with the the distance RS as shown

P = 1/3 × 6√2

P = 2√2

2*1.5² - 1.5/3

2*2.25 - 0.5

4.5 - 0.5

Answer:

x = 2

Step-by-step explanation:

Five to the power of quantity nine minus three x equals one hundred and twenty five.

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

answer is v=5

Step-by-step explanation:

10v-3v=7v

7v=35

v=35/7

v=5

Answer: [tex]v=5[/tex]

Simplify both sides of the equation

[tex]10v+-3v=35[/tex]

[tex](10v+-3v)=35[/tex] (Combine Like Terms)

[tex]7v=35[/tex]

Divide both sides by 7

[tex]7v/7=35/7\\v=5[/tex]

Answer:

h(3x)=18x^2-12x-7

Step-by-step explanation:

[tex]h(x)=2x^2-4x-7\\h(3x) = ?\\\\h(3x) = 2(3x)^2 -4(3x)-7\\\\h(3x)=2\left(3x\right)^2-4\times\:3x-7\\\\h(3x)=3^2\times\:2x^2-4\times\:3x-7\\\\h(3x)=3^2\times\:2x^2-12x-7\\\\h(3x)=18x^2-12x-7[/tex]

Plus a negative value becomes subtraction:

-12 + -23 = -12 -23 = -35

The product is 6x^3-33x^2+45x-6

Answer:

[tex] \boxed{ \bold{ \huge{ \boxed{ \sf{ - 9 \: , \: - 5 \: , - 1 \: , \: 3 \: }}}}}[/tex]

Option C is the correct option.

Step-by-step explanation:

Here, y = 2x - 5 and domain ( D ) = { -2 , 0 , 2 , 4 )

when, x = -2 , Range = 2 × (- 2)- 5 = - 4 - 5 = -9

when, x = 0 , range = 2 × 0 - 5 = 0 - 5 = -5

when x = 2 , range = 2 × 2 - 5 = 4 - 5 = -1

when, x = 4 , range = 2 × 4 - 5 = 8 - 5 = 3

Range = { -9 , -5 , -1 , 3 }

Hope I helped!

Answer:

Step-by-step explanation:

Answer:

The possible error made by Beth is directly multiplying scale of 5 to area of original triangle and getting area of enlarged triangle, which is wrong.

Step-by-step explanation:

Originally Triangle has height =3.5cm and width=4cm

Beth enlarged the same triangle by scale of 5 and calculate area of triangle

The area of triangle as given as A= $$\frac{1}{2} \texrm{ (base) (height)}$$

Area of original triangle is A =$$\frac{1}{2}(3.5 \times 4)$$

Since, The triangle is enlarged by scale of 5

New height =3.5x5 = cm and new width=4x5cm

Area of new triangle is

A' = $$\frac{1}{2} (\textrm{new width} ) ( \textrm{new height})$$

A' = $$\frac{1}{2}(3.5 \times 5)(4\times 5)$$

A' = $$\frac{1}{2}(3.5 \times 4)(5^{2})$$

A' = $$A (5^{2})$$

Now, Looking what error beth made is:

Beth found Area of new triangle is A' = $$\frac{1}{2}(3.5)(4)(5)$$

The possible error made by Beth is directly multiplying scale of 5 to area of original triangle and getting area of enlarged triangle, which is wrong.

Answer:  The distance is about 9.43

Step-by-step explanation:

To find the distance between these numbers find the difference in the x and y values then square them and add them together and finally find the square root of the number you got after adding them.

-5 - 0 = -5

-6 - 2 =  -8

-5^2 + -8^2 = d^2   where d is the distance

25 + 64 = d^2  

89 = d^2

d = [tex]\sqrt{89}[/tex]

d= 9.43

Utilize PEMDAS to solve the problems.

[tex]\frac{-44.288-31.6}{-3.1(6-1.2)}[/tex]

[tex]\frac{-75.888}{-3.1(4.8)}[/tex]

[tex]\frac{-75.888}{-14.88}[/tex]

[tex]5.1[/tex]

Hope this helps.

頑張って!

Answer:

5.1

Step-by-step explanation:

first you subtract -44.288 - 31.6= -75.888

then subtract 6-1.2= 4.8

then multiply -3.1x4.8= -14.88

then divide -75.888/-14.88= 5.1

Step-by-step explanation:

dollars:                     7.5     ----------------------->    ??

chicken wings         5      ----------------------->     1

to get 1 of 5 we have to divide 5÷5 = 1

so we have to divide the dollars by 5 too:   7.5÷5 = 1.5

Answer:

  x = -7y/(4 +5y)

Step-by-step explanation:

You can treat y as though it were a constant. As in any 2-step linear equation, you separate the variable term(s) from the constant term, then divide by the coefficient of the variable.

  4x +5xy = -7y . . . . . subtract 7y

  x(4 +5y) = -7y . . . . . factor out x, so we can see its coefficient

  x = -7y/(4 +5y) . . . . divide by the coefficient of x
