Add 10 to each side
Multiply 4 and 2x + 3 using the distributive property

Pls help me pls pls pls

Answers

Answer 1

Answer:

x = 6

Step-by-step explanation:

Step 1: Write equation

4(2x + 3) = 10x

Step 2: Solve for x

Distribute 4: 8x + 12 = 10xSubtract 8x on both sides: 12 = 2xDivide both sides by 2: 6 = x

The point A(7, -3) is reflected over the point (6, -5) and it's image is point
B. What are the coordinates of point B?

Answers

Answer:

(5, -7)

Step-by-step explanation:

Let the point (6, -5) be M, and point B has coordinates of (x, y)

As the point A(7, -3) reflects over the point M, it becomes the midpoint of segment AB

Using midpoint formula, finding the coordinates of the point B

6 = (7 + x)/2  ⇒ 7 + x = 12 ⇒ x = 12 -7= 5-5 = (-3 + y)/2 ⇒ -3 + y = -10 ⇒ y = -10 + 3 = -7

So the point B is (5, -7)

On a coordinate plane, a line goes through points (0, 8) and (4, 0).

An office supply company ordered 24 cartons of specialty paper. The regular price for a carton of specialty paper is $6.88. They received a discount of $1.75 off each carton. About how much money will the office supply company need to pay for the paper? Which of the expressions gives a reasonable estimate of the answer? A. $5 × 25 B. $6 × 25 C. $7 × 20 D. $9 × 30

Answers

Answer: A. $5 × 25

Step-by-step explanation:

Given the following :

Number of cartons of specialty paper ordered = 24 cartons

Regular price for a carton = $6.88

Discount given off each carton = $1.75

Hence,

Discounted price per carton = $(6.88 - 1.75) = $5.13

Actual amount to be paid for the order :

Discounted price * number of cartons to be ordered

$5.13 * 24

Hence, a reasonable estimate will be :

$5.13 = $5( nearest whole number)

24 can be rounded to 25 (this covers for the $0.13 on the discounted cost per carton)

Reasonable estimate :

$5 × 25

Answer:

The answer is  A. $5 × 25

Step-by-step explanation:

Given that the total number of cartons is 24

the price per carton originally is $6.88

the discount is $1.75

hence the company will have to pay 6.88-1.75= $5.13

hence the price per carton upon removal of the discount is  $5.13

for all 24 cartons, the company will have to pay 24*5.13  

A reasonable estimate from the given option is  

A. $5 × 25

Answers

Answer:  see proof below

Step-by-step explanation:

Note: The given equation cannot be proven. Instead I will prove:

[tex]\cot(2\alpha)=\dfrac{\cot^2\alpha-1}{2\cot \alpha}[/tex]

Use the Reciprocal Identity:  cot A = (cos A)/(sin A)

Use the following Double Angle Identities:

cos (2A) = cos² A - sin² A

sin (2A) = 2 sin A · cos A

Proof LHS → RHS:

LHS:                        cot (2A)

                         [tex]=\dfrac{\frac{\cos^2 \alpha}{\sin^2 \alpha}-\frac{\sin^2 \alpha}{\sin^2 \alpha}}{\frac{2\sin \alpa \cdot \cos \alpha}{\sin \alpha \cdot \sin \alpha}}[/tex]

                         [tex]=\dfrac{\cot^2 \alpha-1}{2\cot \alpha}[/tex]

LHS = RHS [tex]\checkmark[/tex]

Answer:

see proof below

Step-by-step explanation:

cot(2a) = (cot^2a - 1)/2cota

Remember that cotangent is the inverse of tan...

cot = 1/tan => cot(2a) = 1/tan2a

Here I used the formula for tan2a, or in other words tan2a = 2tana/1 - tan^2a

Therefore the inverse of tan2a, 1/tan2a, should be the inverse of 2tanA/1 - tan^2a, or 1 - tan^2a/2tana => 1/tan2a = 1 - tan^2a/2tana = cot(2a)

The reverse is true as well, tan is the inverse of cotangent...tanA = 1/cotA

cot(2a) = 1 - tan^2a/2tana = 1 - (1/cot^2a)/2(1/cota)

= cot^2a - 1/cot^2a * cota/2

= cot^2a - 1/2cota

Find the value of a and b

Answers

Answer:

a=10

b=37

Step-by-step explanation:

a+5 is equal to the opposite line, 15. 10+5=15 therefore, a must equate to 10

3b is the same angle as 111 therefore 3*b has to equate to 111. 111 divided by 3 equals 37. B has to then equate to 37 to make the proper angle.

Hope my explanation wasn't too confusing, and hope this helps! Good luck!!!

Two angles of a triangle measure 12º and 40°.
What is the measure of the third angle of the triangle?
A. 38
B. 48
C. 128
D. 308°

Answers

The sum of the interior angles in each triangle is 180 degrees.

so :

12 + 40 + x = 180

52 + x = 180

x = 180 - 52

x = 128

so the third angle of the triangle is 128 degrees which means C is correct.

Answer:

x = 25°

Step-by-step explanation:

Hi !

We know  : the sum of the measures of any triangle is 180 degrees.

A + B + C = 180°

(3x - 13) + (2x + 4) + (180 - 116) = 180

5x - 13 + 4 + 64 = 180

5x = 180 - 64 - 4 + 13

5x = 125

x = 125 : 5

x = 25°

Good luck !
