Choose the solution set.
{x | x > -2}
{x | x < -2}
{x | x > 2}
{x | x < 2}
Answer:
First divide 3 on both sides to get x by itself, now you have x < -2.

The length of a planet's orbit around a star is approximately 22,200,000 km. It takes the planet about 1230 Earth days to complete a full orbit. What is the planet's average speed in kmh-1 to 3sf?
Answer:
Approximately [tex]12.9\; \rm km \cdot h^{-1}[/tex], assuming that this orbit is circular.
Step-by-step explanation:
The question is asking for a tangential velocity with the unit [tex]\rm km \cdot h^{-1}[/tex]. The unit of the given distance is already in [tex]\rm km[/tex] as required. Convert the unit of the orbital period to hours:
[tex]\begin{aligned}T &= 1230\; \text{day} \times \frac{24\; \rm h}{1\; \text{day}}. = 29520\; \rm h\end{aligned}[/tex].
Calculate the angular velocity [tex]\omega[/tex] of this planet from its orbital period:
[tex]\begin{aligned}\omega &= \frac{2\, \pi}{T} \\ &= \frac{2\, \pi}{29520\; \rm h} \approx 2.1285 \times 10^{-4}\; \rm h^{-1}\end{aligned}[/tex].
Given the radius [tex]r[/tex] of the orbit of this planet, the tangential velocity [tex]v_{\perp}[/tex] of this planet would be:
[tex]\begin{aligned}v_{\perp} &= \omega\, r \\ &\approx 2.1285 \times 10^{-4}\; \rm h^{-1} \times 2.22\times 10^{7}\; \rm km \\ &\approx 4.73 \times 10^{3}\; \rm km \cdot h^{-1}\end{aligned}[/tex].
If the orbit of this planet is circular, the velocity of the planet would be equal to its tangential velocity: [tex]4.73\times 10^{3}\; \rm km \cdot h^{-1}[/tex].
simplify: -4(x - 6) + 3(a - 7)
A. -4x + 3a - 3
B. -4x + 3a + 3
C. -4x + 3a + 45
D. -4x + 3a - 45
We have -4(x - 6) + 3(a - 7) = -4x + 24 + 3a - 21 = -4a + 3a + 3
so the answer is B
ok done. Thank to me :>
Which number is greater explain your reasoning .375 or 3/8? help!
Answer: Neither is greater, they are perfectly equal. Or If it's a trick question, 0.375
Step-by-step explanation:
3 divided by 8 equals 0.375, no rounding or anything. I'm not sure if it is more of a trick, brain melting question, then in that case 0.375 because I suppose it could be a rounded number that represents numbers such as 0.3751, 0.3752, etc.
Determine whether the point (2, -3) is on the graph of each equation-
1) 4x + y= 11
2) 10x - 4y = 23
Answer:
1. Solving for x. Want to solve for y instead?
1 Subtract yy from both sides.
4x=11-y
4x=11−y
2 Divide both sides by 44.
x=\frac{11-y}{4}
x=
4
11−y

I need help please each number has its own equation number it off please
please help !! find the measure of ∠1 and ∠2. justify your answers
Answer:
angle 1 = 45° because vertical angles
angle 2 = 135° because supplementary angles
Step-by-step explanation:
∠1 = ∠a, ∠a = 45°
∠2 + ∠a (45°) = 180°
180° - 45° = 135°
Answer:
Angle 1= 45 degrees, angel 2= 135
Step-by-step explanation:
you know that line b has a 45 degree angle on a 180 total, so to find angle 1 you just move the 45 as they are the same, to find angle b you substract 45 from 180 getting 135

A homeowner collects data about the amount of oil, in gallons, used to heat the house per month for 5 months and the average monthly temperature, in degrees Fahrenheit, for those months. The scatter plot shows the data. The function best fits these data.
Use the function A(t)to determine which of the following statements are true. Select all that apply.
A The homeowner would use about 82 gallons of oil to heat the house for a month with an average temperature of 10 °F.The homeowner would use about 82 gallons of oil to heat the house for a month with an average temperature of 10 ° F.
B The homeowner would use about 85 gallons of oil to heat the house for a month with an average temperature of 15 °F.The homeowner would use about 85 gallons of oil to heat the house for a month with an average temperature of 15 ° F.
C The homeowner would use about 0 gallons of oil to heat the house for a month with an average temperature of 68.5 °F.The homeowner would use about 0 gallons of oil to heat the house for a month with an average temperature of 68.5 ° F.
D The homeowner would use about 5 gallons of oil to heat the house for a month with an average temperature of 55 °F. The homeowner would use about 5 gallons of oil to heat the house for a month with an average temperature of 55 ° F.
E The homeowner would use about 96 gallons of oil to heat the house for a month with an average temperature of 0 °F.
They are doing the calculations, we can say that the alternatives are:
A) True
B) False
C) False
D) False
E) True
For this exercise, the equation should be used:
[tex]A(t)=-1.4t+96[/tex]
So analyzing the first given statement we will have to:
[tex]A(t)=-1.4t+96\\t=10\\A(t)=-14+96=82[/tex]
Based on the calculations, this statement is true, for the second statement we will have:
[tex]A(t)=-1.4t+96\\t=15\\A(t)=-21+96=75[/tex]
From the calculations this statement is false, so for the alternative we will have:
[tex]A(t)=-1.4t+96\\t=55\\A(t)=-77+96=19[/tex]
From the calculations this statement is false, so for the alternative we will have:
[tex]A(t)=-1.4t+96\\t=0\\A(t)=96[/tex]
Based on the calculations, this statement is true.

This should be the answer to the problems, the rounding part got me confused for a second.
Significant digits are numbers after the decimal that aren't 0. So the 1.0792, the 0 isn't a significant digit.

Trina is buying 12 shirts for the drama club.She will choose a style for the blank shirts and then pay additional charge of $2.75 for each shirt to have the club logo. If Trina cannot spend more than $99, how much can she spend on each blank shirt? Write and solve an inequality to find the possible cost of each blank shirt.
Answer:
The most she can spend on each blank shirt is $5.50.
Step-by-step explanation:
In order to set up the inequality, we need to write an expression for the total cost of each shirt wherein the price of each blank shirt is "x". Tina needs to buy 12 shirts and there is an additional charge of $2.75 for each logo. The total cost needs to be less than or equal to $99.
This gives us 12 * (x + 2.75) ≤ 99
We can then distribute:
12x + 12 * 2.75 ≤ 99
12x + 33 ≤ 99
Then subtract 33 from both sides:
12x ≤ 66
And finally divide by 12 on both sides:
x ≤ 5.5
Answer:
Step-by-step explanation:
12x + 2.75*12 < 99 Combine 12 * 2.75
12x + 33 < 99 Subtract 33 from both sides
12x < 99 - 33 Combine
12x <66 Dive by 12
x < 66/12
x < 5.50
The very most she can spend is 5.50 on each shirt. Actually it should be 5.49 which will be less than 99. It will come to 65.88 which is just 12 cents less than 99, but it answers the problem. The problem does not use less than or equal which would mean that 99 is the answer ≤

solve for x, find the measure of all angles plzzzzz!!
Answer:
∠ H = 22.5°, ∠ I = 45° , ∡ J = 112.5°
Step-by-step explanation:
The 3 angles in a triangle sum to 180° , then
x + 2x + 5x = 180 , that is
8x = 180 ( divide both sides by 8 )
x = 22.5
Then
∠ H = x = 22.5°
∠ I = 2x = 2 × 22.5° = 45°
∠ J = 5x = 5 × 22.5° = 112.5°
