Answer:

-3a + 4ab

Step-by-step explanation:

-5a + 2a = -3a

-6ab + 10ab = 4ab

=−5a+−6ab+10ab+2a

=−5a+−6ab+10ab+2a

=(−6ab+10ab)+(−5a+2a)

=4ab+-3a

=4ab-3a

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.

Answer:

The answer is 6.2

Step-by-step explanation:

1) 2.2 + 4 =

2) 11/5 + 4 =

3) 11/5 + 20/5 =

4) 31/5 =

5) 6.2

The answer is 6.2

(-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.

[tex]\large\underline{\sf{Solution-}}[/tex]

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:

what are the values of X?

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:

-10

Step-by-step explanation:

1. First, let's simplify both sides of the equation.

2. To find the missing value to make the equation have infinitely many solutions, we need to make both sides of the equation equal.

3. Given that information, means that 4x - 10 has to equal 4x + (-10) because:

4. Now, with the information in #2, let's see if it's true:

Therefore, the missing number is -10.

Answer:

The six is bigger

Step-by-step explanation:

They both are inside the absolute value sign, meaning, the the numbers are negative, they will turn positive and if they are positive, then they will remain positive. So, in this case 4 and 6 are both positive and remain positive. And obviously 6 is greater than 4 because 6 comes after 4 in a number line.  

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:

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
