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:

c) flip

Step-by-step explanation:  When you multiply both sides by a negative value you make the side that is greater have a "bigger" negative number, which actually means it is now less than the other side! hope this helps!!

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.

Feel free to mark this as brainliest! :D

Step-by-step explanation:

You got the first and last one correct and need flip those for questions 2 and 3.

Answer:

x = 30

Step-by-step explanation:

-6 + 24 = x - 24 + 24

x = 24 + 6 - 24 - 24

x = 30 - 0

 x = 30

Answer:

I may be wrong but I think it's c

Answer:

no because the lines are not parallel

Answer:

what are the values of X?

Answer:

When a decimal goes on forever without repeating, it is an irrational number

Answer:

Step-by-step explanation:

4x -5 = 3x +11 corresponding angles

x= 16

y + 4x - 5 = 180

y + 4(16) = 185

y - 64 =185

y = 121

Answer:

−8x^2+11x−10

Step-by-step explanation:

Answer:

-8x² + 11x - 10

Step-by-step explanation:

5(3x - 2) - 4(2x + 1)x

15x - 10 - 8x² - 4x

11x - 10 - 8x²

= -8x² + 11x - 10

Answer:

Step-by-step explanation:

Perpendicular lines have negative reciprocal slopes. This means that when you multiply the slopes of the perpendicular lines, its product = -1.

Given the linear equation, y = -9x - 1, and the point, (-3, 7):

Since the slope of the given linear equation is: m1 = -9, then it means that the slope of the other line (m2) = 1/9:

m1 × m2 = -1

-9 × 1/9 = -1

Next, we need to find the y-intercept of the other line. The y-intercept is the point on the line where it crosses the y-axis, and has coordinates (0, b). It is also the value of the y-coordinate when its corresponding x-coordinate = 0.

Using the given point, (-3, 7), and the slope of the other line, m2 = 1/9:

We need to substitute these values into the slope-intercept form, y = mx + b, to solve for the y-intercept, (b):

y = mx + b

7 = 1/9(-3) + b

7 =   -1/3 + b

Add 1/3 to both sides of the equation to solve for b:

7 + 1/3  = 1/3 -1/3 + b

22/3 = b

Therefore, the y-intercept (b) = 22/3.

The linear equation of the other line is: y = 1/9x + 22/3

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:

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:

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}

[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]
