ax+3=23 if a=0 plz help

Answers

Answer:

x = [tex]\frac{23}{a}[/tex]

Step-by-step explanation:

Given equation is,

ax + 3 = 23

To solve this equation for the value of x isolate the variable 'x' on the one side of the equation.

Step 1,

Subtract 3 from both the sides of the equation.

ax + 3 - 3 = 23 - 3

ax = 20

Step 2,

Divide the equation by a,

[tex]\frac{ax}{a}=\frac{23}{a}[/tex]

x = [tex]\frac{23}{a}[/tex]

Therefore, x = [tex]\frac{23}{a}[/tex] will be the answer.

The sum of twice a number and 6 is the same as 3 subtracted from the number itself

Answers

The correct answer is 3
answer : 2x + 6 = x - 3

X is the “number”, and twice of X is 2x. You get a sum from addition, so you would add 6 and 2x to get 2x + 6

If 3 was subtracted FROM the number itself, it would be x-3, as 3 is being subtracted FROM the number.

Under a dilation centered at the origin, the vertex, (−2, 4), of a polygon is moved to the point (4, −8) . What is the scale factor of the dilation?

Answers

Answer:

-2

Step-by-step explanation:

I took the quiz.

The scale factor of the dilation is -2.

How does dilation works?

Dilation of a figure will leave its sides get scaled (multiplied) by same number. That number is called the scale factor of that dilation.

It's also called scaling of a figure, but due the involvement of coordinates, it involves a center of a dilation, which is like a pinned point which stays at same place after dilation.

It's like we enlarge or shorten the size of the figure (or keep it same, when scale factor = 1).

Given that Under a dilation centered at the origin, the vertex, (−2, 4), of a polygon is moved to the point (4, −8) .

Then the scale factor of the dilation

(-2k , 4k )= (4, −8)

Thus, -2k = 4

k = -2

Hence, the scale factor of the dilation is -2.

You used a telescope and other mathematics to discover that Jupiter is 5.20 au from the sun. Use the equation to find its orbital period. Round to the nearest tenth of a year.

Answers

Answer:

11.9 au

Step-by-step explanation:

The orbital period of Jupiter around the sun is 11.9 years.

Here, we have,

To solve this question, we need to understand the concept of Kelper's Third Law and how to use it.

we know that,

Kelper's Third Law:

Kelper's Third Law posits that the ratio between the square of the orbital period (T) as well as the average distance cube of a planet away from the Sun is constant for all planets circling the Sun.

T²/r³ = constant

Suppose, we make a reference to Earth, we have:

T_e²/r_e³ = T_j²/r_j³

Making the orbital period (T_j) of Jupiter as the subject, we have:

T_j = √T_e² * r_j³ /r_e³

where;

r_e = avg. distance from earth to sun = 1 au

so, calculating we get,

T_j  = 11.9 years.

Rupert buys a bicycle with a marked price of £ 12500.He gets a rebate of 10% on it. After getting

the rebate ,tax is charged at the rebate of 8%. Find the amount he will have to pay for the bicycle.​

Answers

Answer:

£ 12,150

Step-by-step explanation:

Marked price of bicycle = £ 12500

Rebate = 10%

Amount of rebate = 12500*10/100 = £1250

Rebated price = 12500 - 1250 = £ 11,250

Tax = 8%

Amount of tax = 11250*8/100 = £ 900

Total amount paid for bicycle = Rebated price + amount of tax

= £ 11,250 + £ 900

= £ 12,150
