Answer:

(a) x=1.5 or  x=-4.5

(b) x=-1

(c) x=10  or  [tex]x=\frac{4}{3}[/tex]

Step-by-step explanation:

(a) |2x+3|=6

⇒ 2x+3=6  or  2x+3=-6

⇒ 2x=3 or  2x=-9

⇒ x=1.5 or  x=-4.5

(b) |x-2|=x+4

⇒ x-2=x+4  or  x-2=-(x+4)

x-2=x+4  

-2≠4 x∈Ф

or  x-2=-(x+4)

x-2=-x-4

2x=-2

x=-1

(c) |2x-7|=|x+3|​

⇒ 2x-7=x+3  or  2x-7=-(x+3)

2x-7=x+3

x=10

or  2x-7=-(x+3)

2x-7=-x-3

3x=4

[tex]x=\frac{4}{3}[/tex]

The solutions of modulus equations are shown below:

(a) x=1.5 or x=-4.5

(b) x=-1

(c) x=10 or x=4/3  

Step-by-step explanation:

(a) |2x+3|=6

⇒ 2x+3=6 or  2x+3=-6

⇒ 2x=3 or 2x=-9

⇒ x=1.5 or x=-4.5

(b) |x-2|=x+4

⇒ x-2=x+4 or  x-2=-(x+4)

⇒x-2=x+4  

⇒-2≠4 x∈Ф

or  x-2=-(x+4)

⇒x-2=-x-4

⇒2x=-2

⇒x=-1

(c) |2x-7|=|x+3|​

⇒ 2x-7=x+3 or  2x-7=-(x+3)

⇒2x-7=x+3

⇒x=10

or 2x-7=-(x+3)

⇒2x-7=-x-3

⇒3x=4

⇒x=4/3

Therefore, the solution of modulus equation are as:

(a) x=1.5 or x=-4.5

(b) x=-1

(c) x=10 or x=4/3

Step-by-step explanation:

i supposed each line is 1,2,3,4,5 because it is not given the graph numbers but I hope it could help

54 = 6n     divide 6 on both sides, 6's will cancel on the right.

__    __     solve for 54 ÷ 6 = 9

6      6

n = 9, choice 4 -- final answer

hope this helps :)

The solution of the given equation 54 = 6n will be 9 thus option (D) is correct.

There are many different ways to define an equation. The definition of an equation in algebra is a mathematical statement that demonstrates the equality of 2 mathematical expressions.

As per the given equation,

54 = 6n

Divide by 6 into both sides,

n = 9

Hence "The solution of the given equation 54 = 6n will be 9".

Answer:

2/3

Step-by-step explanation:

REmember that the slope of a line is y/x. To find this, we must use the formula:

y2-y1/x2-x1=y/x

So this is -1 - -7/4- -5. The  -1 -- 7 is actually -1+7. This is 6, meaning y equals 6.

The x is 4 - - 5 is actually 4+5. This is 9, meaning x is equal to 9.

We can now write this as y/x. This would be 6/9.

Once we simplfy this, we get 2/3.

2/3

Answer:

the correct answer is table 2

Answer:

192 km²

Step-by-step explanation:

Surface Area of the triangular prism = 2(Base Area) + Perimeter of Base*height of the prism

✔️Base Area = ½*bh

b = 6 km

h = 8 km

Base area = ½*6*8 = 24 km²

✔️Perimeter of base = 6 + 8 + 10 = 24 km

✔️Height of prism = 6 km

Plug in the values into the equation:

Surface area = 2(24) + 24*6 = 48 + 144

Surface area = 192 km²

Answer:

y = x

Step-by-step explanation:

The equation for slope is y = mx +b. If you look at the line you see that it passes through the origin, this is your y-intercept, 0. If you look at two points at the line and use the rise over run method, you get the slope to be 1. If you substituent these values into the equation you get, y = x.

Answer:

You are doing good I would say! Your average grade would be a B- Or just a normal B Somewhat around there.

Step-by-step explanation:

I hope this helps you and good luck! Bye!

Grade scale:

A → 100-90

B → 89-80

C → 79-70

D → 70

F <70

That being said to see your grade, add all your grades up then divide it by how many grades you have.

That being said, if you add all your grades then divide it by how many grades you have, you should have a 85.6 as your average.

Hence, your average is a B.

Answer:

Will be reveled in part B.

Step-by-step Part A

Using O P N Chart for the profits of $500

O P N represent Original, Part Percent and New original.

O $500 ║100%

P   $410║-18%

N $90   ║82%

I got $410 which is my part percent by subtracting the original by the New original. (500 - 90 = 410)

Now to solve for the part percent and New original which we will know how much money would be given to charity?

Solving for part percent

Part percent x org = Part

(X) x 500 = 90

500x = 90

500      500

x = 0.18 =  18%.

If they sell $500  worth of calculators and donates $90 to charity they are left with $410 and they gave the charity 82%

Part B:

O: $90   ║ 100%

P:   $110  ║-18%

N: $200  ║82%

So this tells me that the charity recived $110.

Answer: (4, 3)

Step-by-step explanation:

Let's use substitution.

So for y in the first equation we will substitute the expression for y in the second.

2x - 3(x-1) =  -1

2x -3x + 3 = -1

-1x + 3 = -1

       -3    -3

-1x = -4

-1x / -1 = -4 / -1

x = 4

Now plug in x for the second equation

y = 4 - 1

y = 3

Now check it using the first equation:

2(4) - 3(3) = -1

8 - 9 = -1

-1 = -1

It's true so it's correct

Area is 140 ft2

perimeter is 54 ft

Answer:

54 and 140

Step-by-step explanation:

If the lengths are 20ft and 7ft, then you can just add 20+20+7+7, which equals 54.

The area is 140, because if you multiply 20 by 7, thn you get 140.
