Given:
The total number of pets can be represented by the expression [tex]y+y+y+y[/tex].
To find:
The expression which is equivalent to the expression for the total number of pets.
Solution:
The expression for the total number of pets is
[tex]y+y+y+y[/tex]
On adding these value, we get
[tex]y+y+y+y=4y[/tex]
Therefore, the expression 4y is equivalent to the given expression for the total number of pets.
Which graph represents an even function?
On a coordinate plane, a hyperbola has a curve in quadrant 1 and a curve in quadrant 3. The curve in quadrant 1 has a vertex at (2, 2) and goes through points (1, 5) and (5, 1). The curve in quadrant 3 has a vertex at (negative 2, negative 2) and goes through points (negative 5, negative 1) and (negative 1, negative 5).
On a coordinate plane, a function has two curves. The first curve is asymptotic to x = negative 3, goes through (negative 2, 0), has a minimum of (negative 1.5, negative 1), goes through (negative 1, 0), and connects with the second curve at (0.5, 3). The second curve starts at (0.5, 3), goes through (2, 0), has a minimum of (2.5, negative 1), goes through (3, 0), and is asymptotic to x = 4.
On a coordinate plane, a parabola opens down. It goes through (negative 2, 0), has a vertex at (0, 4), and goes through (2, 0).
On a coordinate plane, a straight line has a negative slope. It goes through (negative 2, 4), crosses the y-axis at (0, 2), and crosses the x-axis at (2, 0).
Using the concept of even function, it is found that the graph that represents an even function is the third option, given by:
On a coordinate plane, a parabola opens down. It goes through (-2, 0), has a vertex at (0, 4), and goes through (2, 0).
--------------------------------
For an even function, [tex]\mathbf{f(x) = f(-x)}[/tex] for all values of x.--------------------------------
For the first option, [tex]f(1) = 5[/tex], and [tex]f(-1) = -5[/tex], thus [tex]\mathbf{f(x) \neq f(-x)}[/tex], and the function is not even.For the second option, there are asymptotes, thus, it is not even.For the third option, from the information given, [tex]\mathbf{f(-2) = f(2)} = 0[/tex], we suppose this extends for all values of x, thus, it is even, and this is the correct option.For the fourth option, [tex]f(-2) = 4[/tex] and [tex]f(2) = 0[/tex], thus [tex]\mathbf{f(-x) \neq f(x)}[/tex], and the function is not even.A similar problem is given at https://brainly.com/question/16711376

There are 15 pieces of fruit in a bowl and 9 of them are apples. What percentage of the pieces of fruit in the bowl are apples?
Answer:
9 divided by 100 = 0.09 x 15 = 1.35 = 13%
PLs mark me brainliest
Answer:
60%
Step-by-step explanation:
You can first convert 9 out of 15 into 9/15. Then, you can find the percent of 9/15, which is 60% :)

Step-by-step explanation:
ABC=40 and Bd is angle bisector of ABC what is ABD= ?
Answer:
20
Step-by-step explanation:
40 ÷ 2 = 20
its 20 since BD is an angle that bisects " divdes " angles in half.
The measure of angle ABD is 20 degrees and this can be determined by using the properties of the angle bisector.
Given :
ABC = 40 and BD is the angle bisector of angle ABC.
The following steps can be used in order to determine the angle ABD:
Step 1 - According to the given data, BD is the angle bisector of angle ABC.
Step 2 - An angle bisector bisects the angle into two equal parts.
Step 3 - So, the measure of angle ABD is calculated as:
[tex]\angle ABD = \dfrac{\angle ABC}{2}\\\\ \angle ABD = \dfrac{40}{2}\\\\ \angle ABD = 20^\circ[/tex]
So, the measure of angle ABD is 20 degrees.

Li Na is going to plant 636363 tomato plants and 818181 rhubarb plants. Li Na would like to plant the plants in rows where each row has the same number of tomato plants and each row has the same number of rhubarb plants. What is the greatest number of rows Li Na can plant?
Answer:
9 rows
Step-by-step explanation:
Given that:
Li Na wants to plant 63 tomato plants and 81 rhubarb plants
However, Li Na was hoping with the mindset to plant the plants in rows;
where each row possesses the same number of tomato plants and rhubarb plants.
So;
Suppose we choose a given number, Let's say (9) to be the divisor for both the number of tomato plants and rhubarb plants;
Then
63/9 tomato plants = 7 tomato plants
81/9 rhubarb plants = 9 rhubarb plants
Therefore, the greatest number of rows Li Na can plant 7 tomato plants and 9 rhubarb plants = 9

9

Caleb is saving money to buy a bike next year. He makes $75 per week babysitting. So far he has saved $150. Write an inequality to show how many weeks he must babysit so he has at least $800 to spend on the bike, then solve the inequality.
Answer:
x>8.6
Step-by-step explanation:
We want to model an expression for the amount of money Caleb has and how many week he must work to have that amount
given data
amount at hand=$150
weekly saving=$75
let the number of weeks be x
total amount= $800
the expression for this situation is given as
y=mx+c
where y=800
m=75
c=150
substituting we have
800=75x+150
solving for x we have
800-150=75x
650=75x
x=650/75
x=8.6
then he must work for x>8.6 weeks

Sum of all angles in a trapezium equals 360° and we two 90° angles so now,
[tex]90+90+x+(x-60)=360\\180+2x-60=360\\2x=360-180+60\\2x=180+60\\2x=240\\x=240/2\\x=120[/tex]
so now the angles are 90°,90°,120° and 60° i also attached an image so you can understand better.
