Rhonda kept track of the cats at a shelter where she volunteers. She measured how many times per day each cat ate, and she also ranked their activity level on a scale from 1 to 10 each day. She found the line of best fit for the data has the equation y=0.23x+4.1, where x represents the activity level and y represents the number of meals eaten.
If a cat had an activity level of about 9, then it's likely to have eaten about _[blank]_ meals.
Enter the value that correctly fills in the blank.
Round to the nearest whole number, if necessary, like this: 42
If a cat had an activity level of about 9, then it's likely to have eaten about 6 meals.
What is a linear equation?A linear equation is in the form:
y = mx + b
Where m is the rate of change and b is the intial value of y.
Let x represents the activity level and y represents the number of meals eaten. Given that:
y = 0.23x + 4.1
For an activity level of 9 (x = 9):
y = 0.23(9) + 4.1 = 6.17
If a cat had an activity level of about 9, then it's likely to have eaten about 6 meals.

Answer:
27 ) x = 15°,
28 ) x = 18°
Step-by-step explanation:
27 ) We are given angle measures of 85 degrees, consecutively 6x + 5, each forming a linear pair;
85 + ( 6x + 5 ) = 180 ⇒ by definition of linear pair we have two measures of angles that add to 180°,
85 + ( 6x + 5 ) = 180 ⇒ take out ( ),
85 + 6x + 5 = 180 ⇒ combine like terms,
90 + 6x = 180 ⇒ subtract 90 from either side of equation,
6x = 90 ⇒ divide 6 on either side of equation,
Solution; x = 15°
28 ) We are given angle measures of 110 degrees, consecutively 3x + 16, each forming a linear pair;
110 + ( 3x + 16 ) = 180 ⇒ by definition of linear pair we have two measures of angles that add to 180°,
110 + ( 3x + 16 ) = 180 ⇒ take out ( ),
110 + 3x + 16 = 180 ⇒ combine like terms,
126 + 3x = 180 ⇒ subtract 126 from either side of equation,
3x = 54 ⇒ divide 6 on either side of equation,
Solution; x = 18°

Answer:
Multiply the second equation by 2
Step-by-step explanation:
If you do that you will get 2y in the first equation and -2y in the second equation. then, you can add the 2 equations to get rid of y.
Answer:
2
Step-by-step explanation:
For elimination problems, you have to have the variables that you want to cancel out equal in value but opposite in sign.
Since you are trying to cancel out y and you are changing the second equation, look at the first equation.
The y variable is +2y. This means that the second equation with a y variable of -2y.
Since the the second equation's y variable is -y, multiply it by 2.
-y x 2 = -2y

Solve for a in the problem:
-3(9a+2)=129
Answer: a = -5
Step-by-step explanation:
-3 (9a+2)=129
-27a -6 = 129
-27a = 129+6
-27a = 135
a = -135/27
Answer:
a= -5
Step-by-step explanation:
To solve the equation, we want to find out what a is. In order to do this, we have to get a by itself. Perform the opposite of what is being done to the equation. Keep in mind, everything done to one side, has to be done to the other.
-3(9a+2)=129
-3 is being multiplied by 9a+2. The opposite of multiplication is division, so divide both sides by -3.
-3(9a+2)/-3=129/-3
9a+2=129/-3
9a+2=-43
2 is being added on to 9a. The opposite of addition is subtraction, so subtract 2 from both sides.
9a+2-2= -43-2
9a= -43-2
9a= -45
a is being multiplied by 9. The opposite of multiplication is division, so divide both sides by 9.
9a/9= -45/9
a= -45/9
a=-5

Colin rolls a fair dice 18 times.
How many times would Colin expect to roll a number greater than 3?
Answer:
8 or 1/2
Step-by-step explanation:
The requried probability that colin expects to roll a number greater than 3 is 1/2.
What is probability?Probability can be defined as the ratio of favorable outcomes to the total number of events.
Here,
Colin rolls a fair die 18 times.
The total outcome of 1 die = 6
So, for 18 die total outcome = 6 × 18
Now,
Favorable outcome = 4, 5, 6 = 3
A total favorable outcome for 18 dice = 3 × 18
Probability, many times would Colin expect to roll a number greater than 3.
= 3 × 18 / 6 × 18
= 1 / 2
Thus, the requried probability that colin expects to roll a number greater than 3 is 1/2.

O 16°F
O 28°F
Answer: 28 degrees farenheit
Step-by-step explanation: add 22 and 6 for the total of how many degrees -6 is from 22.
If the temperature at dawn is -6°F but by noon it is 22°F.Then 28°F is the difference in temperatures
What is Equation?Two or more expressions with an Equal sign is called as Equation.
The temperature at dawn is -6°F
The temperature at dawn in afternoon is 22°F.
We need to find the difference in temperatures.
Difference is nothing but subtracting one number with another number.
Now subtract -6°F from 22°F.
22°F-(-6°F)
Twenty two degree fahrenheit plus six degree fahrenheit
22°F+6°F
