Answer:

( 5, 3 )

Step-by-step explanation:

I imagine you plug in the given ordered pair to the rule:

( x - 3, y + 9 )

( 2 - 3, 12 + 9 )   ( - is the same as going to the right, so it basically adds ).

                         ( + is the same as going to the right, so it basically subtracts ).

( 5, 3 )

22.6

Step-by-step explanation:

102÷4 1/2=22.6

You can double check this by multiplying 22.6 with 4 1/2, which will give you the answer without it being rounded.

Answer:

7 words per minute

Step-by-step explanation:

63 words = 9 mins

9 mins = 63 words

1 min = 63 words/9

1 min = 7

She can type 7 words per minute

-Chetan K

Answer:

7 words per minute

Step-by-step explanation:

1. To find the unit rate (words per minutes), let's set up two ratios:

2. Now, let's solve for x to find how many words she can type per minute.

Step 1: Cross-multiply.

Step 2: Divide both sides by 9.

Therefore, Christine can type 7 words per minute.

Answer:

It would be distributive property

Step-by-step explanation:

Because you have parenthesis and you need to distribute that 2 to everything in the parenthesis and you will get 2x+6 because 2(x)=2x and 2(3)=6 and when you put those together you get 2x+6

Answer:

the answer for 8) answer= 8

(-2, -10) and (4, r)

The slope of the line (m) = (y₂ - y₁) ÷ (x₂ - x₁)    

⇒                                3    =  (r -(-10)) ÷ (4 - (-2))    

                                  3     =  (r + 10) ÷ (6)

                                18    =  r + 10

                        ∴       r      =  8

Checking my answer:  

Finding the Equation

We can now use the point-slope form (y - y₁) = m(x - x₁)) to write the equation for this line:

                                ⇒  y + 10 =  3 (x + 2)

To test my answer, I have included a Desmos Graph that I graphed using the information provided in the question and my answer. The line passes through both the (-2, -10) point and (4, 8). So r = 8.

Answer:

x+2

=1x+2

=3x.

it's soo easy.

Answer:

using the formula( y2-y1/x2-x1 = m)

m= slope

9 - (-2)/-9 -2 =m

11/ -11 = m

m= -1( slope)

since m is also = y- y1/ x-x1

y - (-2)/ x- 2 = -1= y +2 / x -2 = -1 (cross multipy)

-1 (x -2) = y +2

-x +2 = y + 2

-x -y = 2 -2

-x - y = 0(multiply both sides by -1)

x + y = 0

Answer:

A = 160 mm²

Step-by-step explanation:

The area (A) of a rectangle is calculated as

A = bh ( b is the base and h the height )

Given P = 52 and P = 2(b + h) , then

2(b + h) = 52 ( divide both sides by 2 )

b + h = 26 ( substitute b = 16 )

16 + h = 26 ( subtract 16 from both sides )

h = 10

Then

A = 16 × 10 = 160 mm²

Answer:

its: 160^{2}

Step-by-step explanation:

ps: (b=l)

we have  : P=2 [l+w]

and : P= 52mm

so: 52=2(16mm+w)

    52/2= 16mm+w

     26-16=w

   10=w

so: w=10

and we know that:  area= w*l

so:                          area=10*16

so:          area= 160 mm^{2}

Answer:

y = 50

Step-by-step explanation:

This requires the alternate interior angle theorem, which states that:

The alternate interior angle theorem states that if two parallel lines are cut by a transversal, then alternate interior angles are congruent.

Since 50 degrees is an alternate interior angle to y, y must be equal to 50 degrees.

So,

y = 50

Answer:

y=2x^2+4x−16

Step-by-step explanation:

Assume that the equation of the parabola is y=ax2+bx+c.

Since the parabola passes through the point (−4,0), then 0=16a−4b+c.

Since the parabola passes through the point (2,0), then 0=4a+2b+c.

Since the parabola passes through the point (1,−10), then −10=a+b+c. Thus, we have obtained the following system:

Solving it, we get that a=2, b=4, c=−16. Thus, the equation of the parabola is y=2x^2+4x−16.

The equation of a parabola is  y = -x² + x + 4 with x-intercepts at (-4,0) and (2,0) that passes through the point (1,-10).

A parabola can be represented by the equation:

y = ax² + bx + c

To find the equation of a parabola that has x-intercepts at (-4,0) and (2,0), we can set y equal to 0 and solve for x to find the x-intercepts:

0 = a(-4)² + b(-4) + c

0 = a(2)² + b(2) + c

Solving these equations for a and c gives us:

c = b(-4)

c = -2b

The parabola passes through the point (1,-10), we can substitute the values of x and y into the equation to solve for b:

-10 = a(1)² + b(1) + (-2b)

-10 = a + b - 2b

-10 = a - b

Substituting c = b(-4) into the equation gives us:

y = a x² + b x + b(-4)

Substituting a = -b and solving for b gives us:

y = (-b) x² + b x + b(-4)

y = -b(x² - x - 4)

Since the x-intercepts are at (-4,0) and (2,0), the coefficient of x², which is -b, must be positive. Therefore, we can set b = 1 to get the equation of the parabola:

y = -(1)(x² - x - 4)

y = -x² + x + 4

Thus, the equation of a parabola is y = -x² + x + 4.

Answer:

Jerry is 11.75 years

Step-by-step explanation:

Let us first set up an equation

Let jerry's age be x

4x - 11 = 36 (equation set)

Now we need to slove the equation and find the value of x that is Jerry's age

4x - 11 = 36

Transpose

4x = 36 + 11

4x = 47

x = 47 ÷ 4

x = 11.75 years
