Two of the vertices of a rectangle are (6,1) and (7,1) . IF the rectangle has a perimeter of 18 units, then what are the coordinates of its other two vertices

Answers

Answer:

(6 , -9) (7, -9)

Or

(6, 11) (7, 11)

Step-by-step explanation:

Given: Two of the vertices of a rectangle are (6,1) and (7,1)

Perimeter= 18 units

To get the value of "x"

The distance between Two point can be calculated as (6-7)=-1

Then x= -1

We can get the value of "y" by using expression for perimeter,

The perimeter P= 2x+2y=18

= 2(-1)+2y= 18

-2+2y=18

2y=18+2

2y= 20

y=10

The "y" coordinate can move up or can move down

y1=( 1-10)=-9

Or

y2=( 1+10)=11

Hence, the two other points are;

(6 , -9) (7, -9)

Or

(6, 11) (7, 11)

Given the equation y=1/3x+4 , what is the value of y if x = 3? State your answer in decimal form.

Answers

y=5. if you do the problem you would plug in 3 for x, so the equation would be y=1/3(3)+4. 1/3 times 3 equals 1, so then it would be 1 plus 4 which equals 5. therefore, y=5.

One number is four more than a second number. Two times the first number is 8 more than four times the second number.

Answers

Answer:

The required numbers are:

First number = 4

Second number = 0

Step-by-step explanation:

Let First number = x

second number = y

We are given:

One number is four more than a second number.

Writing in mathematical form:

[tex]x=y+4[/tex]

Two times the first number is 8 more than four times the second

Writing in mathematical form:

[tex]2x=4y+8[/tex]

Now, we will solve these equations by substitution to find values of x and y

Let:

[tex]x=y+4--eq(1)\\2x=4y+8--eq(2)[/tex]

Now, putting value of x from eq(1) into eq(2)

[tex]2x=4y+8\\Put\:x= y+4\\2(y+4)=4y+8\\2y+8=4y+8\\2y-4y=8-8\\-2y=0\\y=0[/tex]

So, we get y=0

Now put value of y in equation 1 to get value of x

[tex]x=y+4\\x=0+4\\x=4[/tex]

So, we get x=4

So, the required numbers are:

First number = 4

Second number = 0

7x-4x=11-2 ---> combine like terms

3x=9 ---> divide by 3

x=3

Answer:

x = 3

General Formulas and Concepts:

Pre-Algebra

Order of Operations: BPEMDAS

Brackets Parenthesis Exponents Multiplication Division Addition Subtraction Left to Right

Equality Properties

Step-by-step explanation:

Step 1: Define Equation

7x + 2 = 4x + 11

Step 2: Solve for x

Subtract 4x on both sides:                    3x + 2 = 11Subtract 2 on both sides:                      3x = 9Divide 3 on both sides:                          x = 3

Step 3: Check

Plug in x into the original equation to verify it's a solution.

Substitute in x:                    7(3) + 2 = 4(3) + 11Multiply:                               21 + 2 = 12 + 11Add:                                     23 = 23

Here we see that 23 does indeed equal 23.

∴ x = 3 is the solution to the equation.

Is it a right triangle?​

Answers

Answer:

No, it is a obtuse triangle instead

Step-by-step explanation:

So, you use pythagorean and theorem which is a^2 + b^2 = c^2

So when you plugin in the numbers, it's 20^2__ 12^2 + 12^2

When you square them you get left with 400__144 + 144

Then, you add 144 + 144 = 288

But since 400 is > than 288, then it's an obtuse triangle.

Answer:

No

Step-by-step explanation:

It does not follow the Pythagorean Theorem, which states that the two shorter sides squared (squared BEFORE added together).  12 squared is 144, and 144 plus 144 equals 288.  20, which seems to be the hypotenuse, squared is 400.  288 does not equal 400.

if an angle is acute then it measures 20 degrees which of the following would be a counterexample? 48 degrees, 90 degrees, 105 degrees, or 180 degrees

Answers

the counter example would be 105 degrees

The counterexample can be the angle can be 105 degrees.

What is counter example statement?

A counterexample is an example in which the hypothesis is true, but the conclusion is false. If you can find a counterexample to a conditional statement, then that conditional statement is false.

However, showing that a mathematical statement is false only requires finding one example where the statement isn't true. Such an example is called a counterexample because it's an example that counters, or goes against, the statement's conclusion.

Given statement:

if an angle is acute then it measures 20 degrees

As, we know counterexample is an example in which the hypothesis is true, but the conclusion is false.

Also, acute angles measure less than 90 degrees.

Thus, the counter example will be if an angle is acute then it measures 105 degrees

It takes Zion three times as long to paint a room as it does Sanjay. How long does it take each person by
himself if they can paint the room together in 30 minutes?

Answers

Answer:

It takes Sanjay 40 minutes and Zion 120 minutes

Step-by-step explanation:

If it takes Sanjay x minutes, it takes Sanjay 3 * x = 3x minutes

Painting together, they spent 30 minutes

1/x + 1/3x = 1/30

4/3x = 1/30

4 * 30 = 3x * 1

120 = 3x

x = 120/3

x = 40 minutes

3x = 3 * 40 = 120 minutes

Answer:

C = 4x+ 16

Step-by-step explanation:

We know that When two parallel lines are cut by a third line, the third line is called the transversal, forming 8 angles.

From the attached diagram,

∠E and (2x+8) are vertical angles formed by the transversal line.

We know that vertical angles are equal.

Hence,

∠E = (2x+8)

∠A and ∠E are called the corresponding girls.

as

∠E = (2x+8)

so

∠A = ∠E = (2x+8)

Therefore,

C = m∠A + m∠E

C = 2x+8 + 2x+8

C = 4x+ 16

Therefore,

C = 4x+ 16

When a 40-foot pole casts a shadow of
30 feet, how tall is a nearby tree that
casts a shadow of 15 feet?

Answers

Set up a ratio with height over shadow height:

40/30 = x/15

Cross multiply:

40 x 15 = 30x

600 = 30x

Divide both sides by 30:

X = 20

The tree is 20 feet tall.

Answer:

20

Step-by-step explanation:

It tells you that a 40 foot pole casts a 30 foot then it asks you how tall is a tree if it casts a 15 foot shadow. We see that 30 is exactly 2 times 15

30 = 2 * 15

So we simply do that to 40 too.

40 / 2 = 20

So 20 is our answer.

Determine all values of k that make each of the following a perfect square trinomial. X^2+8x+k

Answers

Answer:

k can either be

12

or

12

.

Step-by-step explanation:

Consider the equation

0=x2+4x+4

. We can solve this by factoring as a perfect square trinomial, so

0=(x+2)2→x=−2 and−2

. Hence, there will be two identical solutions.

The discriminant of the quadratic equation (b2−4ac) can be used to determine the number and the type of solutions. Since a quadratic equations roots are in fact its x intercepts, and a perfect square trinomial will have

2 equal, or 1

distinct solution, the vertex lies on the x axis. We can set the discriminant to 0 and solve:

k2−(4×1×36)=0

k2−144=0

(k+12)(k−12)=0

k=±12
