What is the slope of the line?

Answer:

im pretty sure #9 is just y=7x... it should be parallel with y=7x-3 since it has y intercept of 0 rather than -3.

Calculation:

[tex]\log ^2_3\left(\frac{1}{3}\right)=-1[/tex]

[tex]\log _3\left(\frac{1}{3}\right)[/tex]

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

[tex]=\log _3\left(3^{-1}\right)[/tex]

[tex]=-1[/tex]

(-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:

( 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 )

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:

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

Let the number be multiplied be 'x'.

Therefore, according to the given conditions:

[tex] \rm\longmapsto {3}^{ - 3} \times x = 4[/tex]

We know that:

[tex] \rm\red⇛ {x}^{ - a} = \dfrac{1}{ {x}^{a} } [/tex]

Therefore:

[tex] \rm\longmapsto \dfrac{1}{ {3}^{3} } \times x = 4[/tex]

[tex] \rm\longmapsto \dfrac{x}{27 } = 4[/tex]

Multiplying both sides by 27, we get:

[tex] \rm\longmapsto27 \times \dfrac{x}{27 } = 4 \times 27[/tex]

[tex] \rm\longmapsto x = 4 \times 27[/tex]

[tex] \rm\longmapsto x = 108[/tex]

So, 108 must be multiplied to get 4.

Verification:

Substitute x = 108, we get:

[tex] \rm = {3}^{ - 3} \times 108 [/tex]

[tex] \rm = \dfrac{1}{27} \times 108 [/tex]

[tex] \rm = \dfrac{1}{27} \times 27 \times 4[/tex]

[tex] \rm =4[/tex]

Answer:

m and n are parallel because if you add 55 and 125 together you get 180

Step-by-step explanation:

If the lines are parallel, ∠3 = 125 (due to corresponding angles) and 55 + ∠3 = 180 (since angles on a straight line add upto 180).

Seeing this is true,

the lines m and n are parallel.

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

Jerry is 11.75 years

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:

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
