solve the following equation show your work 3{-x + (2x + 1)} = x - 1

Answer:

y = 5

Step-by-step explanation:

y + 6 = -3y + 26

4y + 6 = 26

4y = 20

y = 5

Answer:

Y=5

Step-by-step explanation:

1 Subtract 6 from both sides.

y=−3y+26−6

2 Simplify   -3y+26-6−3y+26−6  to  -3y+20−3y+20.

y=−3y+20

3 Add 3y to both sides.

y+3y=20

4.Simplify y+3y to 4y

4y=20

5 Divide both sides by 4.

y=20/4

Simplify 20/4

y=5

Answer:

B

Step-by-step explanation:

Recall that the domain is the span of x-values covered by the graph, while the range is the span of y-values covered by the graph.

From the graph, we can see that the span of x-values covered goes from x=-2 to x=1.

However, note that while at x=-2, the dot is closed, while at x=1, the dot is open. This means that we do not include the point at x=1. Therefore, the domain is all values of x between x=-2 and x=1 not including x=1.

In set notation, this is:

[tex]\{x|-2\leq x<1\}[/tex]

Thus, the domain is all values greater than or equal to -2 but less than 1.

For the range, we can see that the graph spans from y=-4 to y=2. Again, at y=2, the dot is open. Thus, we do not include y=2 in our range.

In set notation, this is:

[tex]\{y|-4\leq y<2\}[/tex]

This is interpreted as all y-values greater than or equal to -4 but less than 2.

The answer is B

Answer:  n =-4

Step-by-step explanation:

Answer:

b) 33.75≤x≤34.25

Step-by-step explanation:

X could equal either 34.25 or 33.75 to give you exactly 0.25. Since the answer can be less than 0.25, it’s all numbers between 33.75 and 34.25, including those two numbers.  (That’s why the circles are filled in, unlike answer a).

Answer:

Step-by-step explanation:

Addition property is used in an equation when the same value is added to both sides of the equation to simplify such equation.

Given the equation 2y-40=-18 to simplify the equation further we need to first add 40 to both sides of the equation thereby justifying the addition property as shown;

2y-40 + 40 =-18+40

2y = 40-18

2y = 22

We will also apply the division property here. Division property is used when both sides of an equation is divided by a number without affecting the equality rule.

Dividing the resulting equation by 2:

2y/2 = 22/2

y = 11

Hence the justification for the equation 2y-40=-18 are both adition and division property.

Answer:

x = [tex]\frac{3c-4y}{m}[/tex]

Step-by-step explanation:

Given

mx + 4y = 3c ( subtract 4y from both sides )

mx = 3c - 4y ( divide both sides by m )

x = [tex]\frac{3c-4y}{m}[/tex]

Answer: -6

Step-by-step explanation:

Let x= the number

2x-4=x-10 ⇔ according to the statement

  x-4=-10 ⇔ subtraction property of equality (subtract x from both sides)

     x=-6 ⇔ addition property of equality (add 4 on both sides)

Hope this helps!! :)

Please let me know if you have any question

Answer:

n = -6

Step-by-step explanation:

Alright so this can be solved by using variables. Let's say n = number.

4 subtracted from twice a number can be represented as 2n - 4.

10 less than the number can be represented as n - 10.

Since the outcome of the first expression is equal to the second, we can set them equal to each other to solve:

2n - 4 = n - 10.

Then you isolate n by adding 4 to both sides...

2n = n - 6,

... then subtracting n from both sides:

n = -6

There you go!

2. [tex]b = 3[/tex]

3. [tex]n = 6[/tex]

4. [tex]b = 1[/tex]

Step-by-step explanation:

I’m going to assume the equations are as following - you made it a bit hard to read.

[tex]x - 7 = 0[/tex]

[tex]-15 = b - 18[/tex]

[tex]4 = n-2[/tex]

[tex]b-(-16) = 17[/tex]

I’m just shooting guesses here, if I said an equation wrong PLEASE let me know.

We can solve each equation by isolating x on one side.

Number 1:

[tex]x - 7 = 0\\\\x - 7 + 7 = 0 + 7\\\\x = 7[/tex]

Number 2:

[tex]-15 = b - 18\\\\-15 + 18 = b - 18 + 18\\\\3 = b[/tex]

Number 3:

[tex]4 = n-2\\\\4 + 2 = n - 2 + 2\\\\n = 6[/tex]

Number 4:

[tex]b-(-16) = 17\\\\b+16=17\\\\b + 16 - 16 = 17 - 16\\\\b = 1[/tex]

Answer:

Step-by-step explanation:

To prove a quadrilateral a parallelogram we prove,

1). Length of opposite sides are equal.

2). Slopes of the opposite sides are same.

Length of AB = [tex]\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

                      = [tex]\sqrt{(2+1)^2+(-5+2)^2}[/tex]

                      = [tex]3\sqrt{2}[/tex]

Length of BC = [tex]\sqrt{(2-1)^2+(-5+2)^2}[/tex]

                      = [tex]\sqrt{10}[/tex]

Length of CD = [tex]\sqrt{(1+2)^2+(-2-1)^2}[/tex]

                      = [tex]3\sqrt{2}[/tex]

Length of AD = [tex]\sqrt{(-1+2)^2+(-2-1)^2}[/tex]

                      = [tex]\sqrt{10}[/tex]

Therefore, AB = CD and BC = AD (Opposite sides are equal in length)

Slope of AB = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]

                    = [tex]\frac{-5+2}{2+1}[/tex]

                    = -1

Slope of BC = [tex]\frac{-5+2}{2-1}[/tex]

                    = -3

Slope of CD = [tex]\frac{1+2}{-2-1}[/tex]

                    = -1

Slope of AD = [tex]\frac{-2-1}{-1+2}[/tex]

                    = -3

Slope of AB = slope of CD and slope of BC = slope AD

Therefore, AB║CD and BC║AD

Hence ABCD is a parallelogram

Answer:

Only Annabelle is correct.

Step-by-step explanation:

So we have the expression:

[tex](4^27^5)(4^37^2)[/tex]

When multiplying exponents with the same base, we can use the following property:

[tex]x^ax^b=x^{a+b}[/tex]

Essentially, we add the exponents together.

So, first group them:

[tex]=(4^24^3)(7^57^2)[/tex]

Use the property:

[tex]=4^{2+3}7^{5+2}[/tex]

And so our answer is:

[tex]=4^57^7[/tex]

So, Annabelle's answer is correct.

Navene incorrectly used the property. The property adds the exponents, it doesn't multiply them.

So, only Annabelle is correct.

And that's our answer :)

Answer:

2 19/5

Step-by-step explanation:

4 7/9 ÷ 1 7/12

start by turning them into improper fraction by multiplying the denominator to the whole number and adding the product to the numerator , you will get :

42/9 ÷ 17/12

42/9 * 12/17 ( reciprocal )

42/3 * 4/17 (9 and 12 can be cut smaller because both are in 3's table)

= 172/51

turn this into mixed fraction by -

Divide the numerator by the denominator.

Write down the whole number answer

Then write down any remainder above the denominator

you will get = 2 19/5

4 7/9 divided by 1 7/12 will be 3 1/57.

The first thing to do is to change the mixed fraction to improper fraction and this will be:

= 4 7/9 ÷ 1 7/12

= 43/9 ÷ 19/12

Then we change the division sign to multiplication and this will be:

= 43/9 × 12/19

We then reduce to lowest term

= 43/9 × 12/19

= 43/3 × 4/19

= 172/57

= 3 1/57

In conclusion, 4 7/9 divided by 1 7/12 is 3 1/57.

Answer:

w = (-6)/7

Step-by-step explanation:

Solve for w:

-w/2 - 3/5 = w/5

Hint: | Put the fractions in -w/2 - 3/5 over a common denominator.

Put each term in -w/2 - 3/5 over the common denominator 10: -w/2 - 3/5 = (-5 w)/10 - 6/10:

(-5 w)/10 - 6/10 = w/5

Hint: | Combine (-5 w)/10 - 6/10 into a single fraction.

(-5 w)/10 - 6/10 = (-5 w - 6)/10:

(-5 w - 6)/10 = w/5

Hint: | Make (-5 w - 6)/10 = w/5 simpler by multiplying both sides by a constant.

Multiply both sides by 10:

(10 (-5 w - 6))/10 = 2 w

Hint: | Cancel common terms in the numerator and denominator of (10 (-5 w - 6))/10.

(10 (-5 w - 6))/10 = 10/10×(-5 w - 6) = -5 w - 6:

-5 w - 6 = (10 w)/5

Hint: | In (10 w)/5, divide 10 in the numerator by 5 in the denominator.

10/5 = (5×2)/5 = 2:

-5 w - 6 = 2 w

Hint: | Move terms with w to the left hand side.

Subtract 2 w from both sides:

(-5 w - 2 w) - 6 = 2 w - 2 w

Hint: | Combine like terms in -5 w - 2 w.

-5 w - 2 w = -7 w:

-7 w - 6 = 2 w - 2 w

Hint: | Look for the difference of two identical terms.

2 w - 2 w = 0:

-7 w - 6 = 0

Hint: | Isolate terms with w to the left hand side.

Add 6 to both sides:

(6 - 6) - 7 w = 6

Hint: | Look for the difference of two identical terms.

6 - 6 = 0:

-7 w = 6

Hint: | Divide both sides by a constant to simplify the equation.

Divide both sides of -7 w = 6 by -7:

(-7 w)/(-7) = 6/(-7)

Hint: | Any nonzero number divided by itself is one.

(-7)/(-7) = 1:

w = 6/(-7)

Hint: | Simplify the sign of 6/(-7).

Multiply numerator and denominator of 6/(-7) by -1:

Answer: w = (-6)/7

Answer:

-5/10w - 3/5 = 2/10w

- 3/5 = 7/10w

-30 = 35w

-30/35 = w

-6/7 = w

Answer:

264 in²

Step-by-step explanation:

The figure given can be divided into 5 parts as shown in the attachment below, and it would consists of the following with their dimensions:

2 triangles of the same dimensions labelled 1 and 2:

Base (b) = 16 in

Height (h) = 10 in

Area = 2*½*b*h = 2*½*16*10 = 160 in²

2 rectangles of the same dimensions labelled 4 and 5:

length (l) = 5 in

width (w) = 4 in

Area = 2(l*b) = 2(20) = 40 in²

1 rectangle labelled 3:

length (l) = 16 in

width (w) = 4 in

Area = l*w = 16*4 = 64 in²

Total area of the figure = 160 + 40 + 64 = 264 in²
