Answer:

x<5

Step-by-step explanation:

−2(x−7)>4

Step 1: Simplify both sides of the inequality.

−2x+14>4

Step 2: Subtract 14 from both sides.

−2x+14−14>4−14

−2x>−10

Step 3: Divide both sides by -2.

−2x ÷ −2 > −10 ÷ −2

x<5

Step-by-step explanation:

12x - 17x = 8 + 4 - 42

-5x = -30

x = 6

Step-by-step explanation:

They undergo internal fertilization: True Most reptiles undergo internal fertilization sexually when the sperm of a male reptile enters the cloaca of female reptiles, fertilizing the egg.

Their urine is concentrated: False Reptiles do not have the ability to produce liquid urine that is more concentrated than their own body fluid because they lack a structure in their nephron called the Loop of Henle.

They use their skin for gas exchange: False They cannot use their skin as an organ of gas exchange. Reptiles depend entirely on their lungs for this.

They have two-chambered hearts: False They have three-chambered hearts.

They are covered in scales: True All reptiles are covered in scales (snakes, lizards, turtles, etc.)

Answer:

x = 4

Step-by-step explanation:

log₃[1 + log₃(2ˣ - 7)] = 1

log₃[1 + log₃(2ˣ - 7)] = log₃(3)

1 + log₃(2ˣ - 7) = 3

log₃(2ˣ - 7) = 2

log₃(2ˣ - 7) = log₃(3)²

2ˣ - 7 = 9

2ˣ = 9 + 7

2ˣ = 16

2ˣ = 2⁴

x = 4

By putting x = 4 in the original equation,

log₃[1 + log₃(2⁴ - 7)] = 1

log₃[1 + log₃(16 - 7)] = 1

log₃[1 + log₃(9)] = 1

log₃[1 + log₃(3)²] = 1

log₃[1 + 2] = 1

log₃[3] = 1

1 = 1

Therefore, x = 4 is not the extraneous solution and there is no error in your answer.

Answer:

Answer B. 150.8

Answer:

(69,979)

Step-by-step explanation:

In the coordinates, x is represented as 69. We can now insert this into the equation.

y = 13x + 82

Now to insert x.

y = 13(69) + 82

Now we can multiply 13 by 69.

13*69 = 897

Now fix the equation.

y = 897 + 82

Now add to get our y.

897 + 82 = 979

Substitute into the equation.

y = 979

And there is our answer. We now need to put this into the coordinates.

And we get our final answer of (69,979).

Hope this helps. Have a nice day.

Answer:

x=7

Step-by-step explanation:

2{x+8}+5{x-1}=60

Distribute

2x+16+5x-5 = 60

Combine like terms

7x +11 = 60

Subtract 11 from each side

7x+11-11 = 60-11

7x = 49

Divide each side by 7

7x/7 = 49/7

x = 7

Answer:

You can always ask the tutor they give the correct answer :))

Step-by-step explanation:

(8x² + 3xy -20y²)-(-4x²+3xy+20y²)

= 8x² + 3xy -20y² + 4x² -3xy - 20y²

= 8x² + 4x² + 3xy - 3xy -20y² -20y²

= 12x² - 40y²

Answer:

2x(x - 3)²

Step-by-step explanation:

We can simplify this a lot by first factoring 2x out of each term:

2x³ - 12x² + 18x

= 2x(x² - 6 + 9)

We can then factor the trinomial fairly easily, as it's a perfect square:

= 2x(x - 3)²

Answer:

449,999

Step-by-step explanation:

Given that:

Greatest whole number that round to 400,000 when rounding to the nearest hundred thousand :

To obtain the greatest whole number which rounds to 400,000, the whole number is greater Tha 400,000 and its 10 thousand digit in the number or value to be rounded must be lesser than 5.

The value would be 449,999 ; here z the 10 thousand value which is 4 is rounded to zero since it is not up to 5 and the subsequent digits also rounded to 0 to give ;

400,000 (nearest hundred thousand).

Answer:

n = 6

Step-by-step explanation

Number of sides = 360/Measure of exterior

Measure of exterior = 180 - interior angle

Exterior angle = 180 - 120

Exterior angle  = 60 degrees

Substitute into the formula

number of sides = 360/60

number of sides = 6

Hence the number of sides required is 6

Answer:

hello your question is incomplete below is the complete question

To purchase $14,500 worth of restaurant equipment for his business, Hans made a down payment of $1800 and took out a business loan for the rest. After 2 years of paying monthly payments of $562.88. , he finally paid off the loan. What was the total amount  Dean ended up paying for the equipment ( including the down payment and monthly payments )

answer: $15309.12

Step-by-step explanation:

Initial cost of equipment = $14500

Down payment = $1800

cost of equipment = 14500 - 1800 = $12700

Monthly payment = $562.88

Therefore payment made after 2 years = ( 562.88 * 24 ) = $13509.12

Total amount paid by Dean for the equipment

= down payment + monthly payments

= $1800 + $13509.12

= $15309.12
