Answer:
-12y^10
Step-by-step explanation:
First let's rewrite the equation using the commutative property of multiplication
3 x (-4)y^8y^2
Multiply y^8 by y^2 by adding the exponents
y^8+y^2= y^10
3 x (-4)y^10
Now multiply 3 by -4
3 x -4= -12
Finally put them together
-12 + y^10= -12y^10
Answer:
[tex] - 12 {y}^{10} [/tex]
Step-by-step explanation:
We are to simplify:
[tex](3 {y}^{8} )( - 4 {y}^{2} )[/tex]
3 multiplies -4 to get -12, as shown below
[tex]3 \times - 4 = - 12[/tex]
Now, to multiply the exponents which are 8 and 2, we have to use the exponential rule of multiplication: [tex] {a}^{b} \times {a}^{c} = {a}^{b + c} [/tex]
Therefore:
[tex] {y}^{8} \times {y}^{2} = = > {y}^{8 + 2} = {y}^{10} [/tex]
Now, combine -12 and [tex] {y}^{10} [/tex] to get your final answer.
Final answer [tex] = - 12 {y}^{10} [/tex]

Answer: 750 times more stars.
Step-by-step explanation:
You already know the answer (Galaxy B is quite obviously larger) but the amount of times larger is dependent on the value you get when you divide;
6 billion by 8 million (6,000,000,000/8,000,000)

David wants to start a lawn care business. He offers his clients two different service options: Plan A charges $20 per month plus $5 an hour. Plan B charges $30 per month plus $3 an hour. He used the system of equations below to determine how much money he can make on both plans. y = 5x + 20 y = 3x + 30 If x represents the number of hours he works, and y represents the total money he makes, how many hours would he have to work to make the same amount of money with both plans?
Answer:
1440 hrs
Step-by-step explanation:
5 is the number of hours he works, and 45 is the total money David makes.
What is Equation?Two or more expressions with an Equal sign is called as Equation.
Given that David offers his clients two different service options.
Plan A charges $20 per month plus $5 an hour.
Plan B charges $30 per month plus $3 an hour.
y = 5x + 20 and y = 3x + 30 are the system of equations to determine how much money he can make on both plans.
y = 5x + 20..(1)
y = 3x + 30..(2)
Substitute equation 2 from equation 1.
y-y=5x+20-3x-30
0=2x-10
2x=10
Divide both sides by 2
x=5.
Now substitute x in equation 1.
y=25+20
y=45
Hence, 5 is the number of hours he works, and 45 is the total money David makes.

The model y=1.8x−76.9 represents the relationship between the temperature (°F) and the number of ice cream cones sold. Using the linear regression model, approximate the number of ice cream cones sold when it is 85°F. Round your answer to the nearest whole number.
When it is 85°F, they will sell approximately _ ice cream cones.
Graph of linear equation will be always straight line.
Number of ice cream cones sold be 76.
The relationship between the temperature (°F) and the number of ice cream cones sold is given by model,
[tex]y=1.8x-76.9[/tex]
Where x represent temperature and y represent number of ice cream cone sold.
When temperature is 85°F , it means that , x = 85°F
So, [tex]y=1.8*85-76.9\\\\y= 76.1[/tex]
Thus, number of ice cream cone sold is to be 76.

Lol can someone help me understand this i’m mad confused and I’m tryna get my grade up
Answer:
y-(-8)=4(x-2)
Step-by-step explanation:
This is point-slope form. Point-slope form is y-y₁=m(x-x₁), this is y minus the change in y equals slope (slope is m) times x minus the change in x. An ordered pair is (x, y). You just plug in the missing values. This will get you y-(-8)=4(x-2). I hope this helps! Also, make sure not to put the parenthesis around -8 in the actual box!

The National Science Institute was conducting research on the speed of Cheetahs. After
concluding their research, they were able to predict the cheetahs speed or distance when given
certain times or miles that the cheetah traveled. Complete the table of values and graph the
data on the coordinate plane.
Time(min) |. Distance(mi)
0. 0
1/2. 2/3
1. ?
? 3
8. ?
Answer the following questions using the information above.
1.) Is the relationship proportional? Why or why not?
2.) What is the unit rate?
The table of values is:
Time(min) | Distance(mi)
0 0
1/2 2/3
1 4/3
9/4 3
8 32/3
1) The relationship between Distance and Time is proportional.
2) The unit rate is 4/3 miles
To complete the table, we need to find the missing values of time and distance.
We use the relation between Distance, speed and time ,to find the missing values, which is given by,
Distance = Speed x Time
Given when time = 1/2 minute, the distance = 2/3 miles
Speed = Distance/Time
= 2/3 x 2/1
= 4/3 mile per minute.
This is the constant speed of the cheetah. We use this constant speed to find the other values to complete the table.
So If we take 'y' as the distance and 'x' as the time, then the relationship between time and distance can be expressed as
y = (4/3)x [since Distance = Speed x Time ].
So this relationship is proportional because there is a constant of proportionality 4/3 in the linear equation above and hence can be graphed as well.
The graph will contain the time values on the x-axis and distance values on the y-axis.
So now we need to find the missing values on the table using the above linear equation.
When time, x = 1 minute, distance, y = (4/3) x 1 = 4/3 miles.
When distance, y = 3 miles, 3 = (4/3)x
⇒ time, x = 3 x (3/4) = 9/4 minutes.
When time, x = 8 minutes, distance, y = (4/3) x 8 = 32/3 miles.
So the table is:
Time(min) | Distance(mi)
0 0
1/2 2/3
1 4/3
9/4 3
8 32/3
The unit rate refers to the y-value when the x-value is unity(1). So the unit rate here is found when time = 1 minute.
From the table, distance when time = 1 minute is 4/3 miles.
Hence, unit rate = 4/3 miles.
