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.

The floor of a living room is 7m by 5m. How many 50cm square tiles are required?
Answer
7m x 5m = 35, then multiply by 100, so then the answer is 3,500
Step-by-step explanation:
The number of tiles that can fit in the living room is 7000.
What is the arithmetic operator?Arithmetic operators are four basic mathematical operations in which summation, subtraction, division, and multiplication involve.,
As per the given dimension of the living room,
7m by 5m
Area = 7 x 5 = 35 m²
Area of one tile = 50 cm² = 0.005m²
With this surface area the number of tiles that can be fit,
35/0.005 = 35000/5 = 7000
Hence "The number of tiles that can fit in the living room is 7000".

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°

2
-2
0
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

What are the slope and the y-intercept of the linear function that is represented by the equation y = negative 10 x + 1? The slope is –10, and the y-intercept is –1. The slope is –10, and the y-intercept is 1. The slope is –1, and the y-intercept is –10. The slope is 1, and the y-intercept is –10.
Answer:
2. the slope is -10 and y-intercept is 1
Step-by-step explanation:
hope this helps!
Answer:
B. The slope is –10, and the y-intercept is 1.
Step-by-step explanation:
Our equation is y = -10x + 1. Notice that this is of the form y = mx + b, which is called the slope-intercept form because it literally gives us the slope and y-intercept in the equation:
- m: this is the slope value
- b: this is the y-intercept
Here, m = -10, which means the slope is -10. Also, b = 1, so the y-intercept is 1.
Thus, the answer is B.
rosa pays a monthly membership fee at a gym. She also pays $5 for each cycling class she takes. in May, she took 4 cycling classes and her total cost for the month was $55. in June, Rosas total cost was equal to twice the membership fee. How many cycling classes did she take?
Answer:
14 classes
Step-by-step explanation:
if she pays $5 per cycling class than in May she payed $20. $55 - $20 = 35. If in June the cost was double the membership fee than 35 x 2 = 70. Than you do 70 / 5 = 14.
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
