Determine the equation of a line that passes through the point (3,-2) and is PERPENDICULAR to the equation
y= 3x - 1

Answer:

x = -2

Step-by-step explanation:

Isolate the variable (or x) by subtracting 25 from both sides.

We do this and get 7x = -14

Divide both sides by 7 and we get x = -2

Answer:

1ft≤h≤25ft

Step-by-step explanation:

The area of a rectangle is expressed as;

Area = Length * height

A = Lh

If the area of a rectangle is at most 400 square centimeter, this is expressed as;

A ≤400

≤ means at most that is the area of the rectangle cannot be greater than 400

Substitute the given value into the inequality expression

Lh ≤ 400

Given

L = 16

16h ≤ 400

Divide both sides by 16

16h/16 ≤ 400/16

h ≤ 400/16

h ≤ 25

Hence the possible values of the height are with the range 1ft≤h≤25ft since we cannot have a negative value for the dimension

Answer: 1020p

Step-by-step explanation:

The total cost of the bells will be:

= 12p × 30 = 360p

She sells 3/5 of the bells for 50p each. This will be:

= (3/5 × 30) × 50

= 18 × 50p

= 900p

She sells the remaining 2/5 for 40p each. This will be:

= (2/5 × 30) × 40

= 12 × 40

= 480p

Then, total revenue will be:

= 900p + 480p

= 1380p

Profit = Revenue - Cost

= 1380p - 360p

= 1020p

Answer:

x = 104 degrees

y = 76 degrees

z = 104 degrees

quadrilateral have to add up all of their interior angles to 360 degrees.

x and c are  opposite interior angles.  after finding that you have to add those 2 together (208) and subtract that from 360. You should get 152. However andgle B (angle y) and angle D are also opposite interiors so you divide 152 by 2 and get 76 degrees.

Also a straight line is 180 degrees so you subtract the degrees of D by 100 to get angle z.

Answer:

m∡x = 104°

m∡y = 76°

m∡z = 104°

Step-by-step explanation:

m∡A ≅ m∡C

m∡B ≅ m∡D

to find m∡B:  2(104) + 2y = 360

                       208 + 2y = 360

                       2y = 152

                        y = 76

m∡z:  180° - 76° = 104°

Answer:

D

Step-by-step explanation:

Solving the inequality

- 3x + 5 > 4 ( subtract 5 from both sides )

- 3x > - 1

Divide both sides by - 3, reversing the symbol as a result of dividing by a negative value.

x < [tex]\frac{1}{3}[/tex]

The only value not less than [tex]\frac{1}{3}[/tex] is 4 → D

Answer:

x=−7

Step-by-step explanation:

Step 1: Add 5 to both sides.

−3x−5+5=16+5

−3x=21

Step 2: Divide both sides by -3.

−3x/−3=21/−3

Answer:

x = -7

Step-by-step explanation:

Hello.

I can help.

To solve algebraic equations all you need to do is get rid of everything on the side of the x except the x.

Lets look at your problem.

-3x - 5 = 16

An important thing to note is we are going to get rid of things on the left side of the = by doing the opposite of what they're doing.

If it is addition we do subtraction

If it is division we do multiplication

and so on.

ALSO

Whatever we do on the left side of the = we must do the same thing to the number on the right.

Now, let us start trying to solve this.

You always want to start with the number that is alone without the variable / letter.

So :

-3x - 5 = 16

Since it is -5 lets add 5 to make it 0 and get rid of it.

-3x - 5 = 16

     +5  +5

(Remember to do it to the other side of the = too)

Now we have :

-3x = 21

Now we want to get rid of the 3 attached to the x. And since these two are multiplying we need to divide the -3 by itself to make it 1. Since one number divided by itself is 1.

So like this :

-3x = 21

/-3    /-3

NOTE : When you are dividing or multiplying negative numbers there is an important key to be aware of. Here is a short key to go off of :

- x - = +

- x + = -

So a negative times a negative will be a positive.

While a positive times a negative, the negative will over ride the positive and the answer will be negative.

Going back to the equation, here is what we do :

-3x / -3 = +x (Not negative)

And :

21 / -3 = -7 (Is negative)

So now our equation is :

x = -7

And this is our final answer.

I hope this helped.

Answer:

infinitely many solutions

Step-by-step explanation:

The equation 5(x - 3) = 10x - 15 has one solution, which is x = 0.

Let's simplify the given equation:

5(x - 3) = 10x - 15

Distribute the 5 on the left side:

5x - 15 = 10x - 15

Now, let's isolate the variables on one side by subtracting 5x from both sides:

-15 = 5x - 15

Next, add 15 to both sides:

0 = 5x

Divide both sides by 5:

0/5 = 5x/5

0 = x

Therefore, the equation simplifies to 0 = x. This means that x is equal to 0.

So, the equation 5(x - 3) = 10x - 15 has one solution, which is x = 0.

Answer: None

Step-by-step explanation:

You have to either solve for x or y by getting x/y in both equations the same value to cancel them out. In my steps I will solve for x:

-20x - 16y = -20

10x + 8y = 10

----------

1.) Multiply 10x + 8y = 10 by 2

-20x - 16y = -20

20x + 16y = 20

2.) Cancel out values

All parts cancel out.

Rephrase the expression

2 times a number is increased by 4, it is the same as 25 decreased by the number

2x+4=25-x

Calculate

Given

2x+4=25-x

Add x on both sides

2x+4+x=25-x+x

3x+4=25

Subtract 4 on both sides

3x+4-4=25-4

3x=21

Divide 3 on both sides

3x/3=21/3

x=7
