Answer:
Not Linear
Step-by-step explanation:
A linear equation is an equation of a straight line, which means that the degree of a linear equation must be 0 or 1 for each of its variables. In this case, the degrees of the variables in the equation violate the linear equation definition, which means that the equation is not a linear equation.
Answer:
That equation is nonlinear.

Find the values of x and y in the isosceles triangle
Answer:
X = 66 y = 48
Step-by-step explanation:
base angles of an isosceles are the same so x is 66
Angles in a triangle add up to 180
66 + 66 = 132
180 - 132 = 48

Solve the inequality. Graph the solution.
−8 ≤ z + 6.4
Answer:
Solve for z- by simplifying both sides of the inequality, then isolating the variable.
Inequality Form:
z≥−14.4
Step-by-step explanation:
The solution of the inequality −8 ≤ z + 6.4 is z ≥ 14.4.
What are open and closed circles?A closed circle on a point represents including(less than or equal to or greater than or equal to) the point and an open circle on a point represents we are not including(strictly less than or greater than) that point.
The solution of the inequality −8 ≤ z + 6.4 is,
z ≥ 6.4 + 8.
z ≥ 14.4.
∴ The graph of the inequality z ≥ 14.4 will be a line denoted by a closed circle at 14.4 to infinity or a region greater than or equal to 14.4.

What is the range in the function f(x) = 2x + 5 when the domain is {-2,-1, 3)?
PLEASE HELP 25 POINTS
Answer:
Range: {1, 3, 11}
Step-by-step explanation:
To find the range, just substitute the inputs into the function to find the outputs.
f(-2) = 2(-2) + 5
f(-2) = -4 + 5
f(-2) = 1
f(-1) = 2(-1) + 5
f(-1) = -2 + 5
f(-1) = 3
f(3) = 2(3) + 5
f(3) = 6 + 5
f(3) = 11
So the range is: {1, 3, 11}.
a group of 4 pupils can take 2 weeks to do a certain job.how long will 12 pupils take to complete the job if they work at the same rate
Answer:
6 weeks
Step-by-step explanation:
Set up a proportion where x is the amount of time with 12 pupils:
[tex]\frac{4}{2}[/tex] = [tex]\frac{12}{x}[/tex]
Cross multiply and solve for x:
4x = 24
x = 6
So, it will take 12 pupils 6 weeks to complete the job.

What is the image of the point (-3,-5) after a rotation of 180° counterclockwise about the origin?
Under a rotation of
180
∘
about the origin
a point (x ,y) → (-x ,-y)
hence (-3 ,4) → (3 ,-4)
The point (-3,-5) after a rotation of 180° counterclockwise about the origin changes to (3, 5).
What are transformations?Two-dimensional figures can be transformed mathematically in order to travel about a plane or coordinate system.
Dilation: The preimage is scaled up or down to create the image.
Reflection: The picture is a preimage that has been reversed.
Rotation: Around a given point, the preimage is rotated to create the final image.
Translation: The image is translated and moved a fixed amount from the preimage.
We also know that when a point P(x, y) is rotated 180° about the origin it changes to ( -x, - y).
Given, Point (-3,-5) after a rotation of 180° counterclockwise about the origin.
∴ The new coordinates of the points are (3, 5).

Logan was paid $45 for 3 hours of work on Friday. He was paid $90 for 6 hours of work on Saturday.
Are Logan’s pay rates, in dollars per hour, proportional for these 2 days? please help
Answer:
Yes, Logan's pay rates are proportional for those 2 days.
Step-by-step explanation:
First, we have to figure out what 6 divided by 3 is.
6 ÷ 3 = 2
So, now we have to divide 90 by 45.
90 ÷ 45 = 2.
So, yes it is proportional because 6 ÷ 3 = 2 and 90 ÷ 45 is also 2 so yes it is proportional.

Inequalities are used to represent unequal expressions.
The inequality is:
⇒ H ≤ 46
What is Inequality?A relation by which we can compare two or more mathematical expression is called an inequality.
Given that;
The height (h) is said to be no greater than 46 inches.
Here, The text "no greater than" means less than or equal to.
Hence, the inequality is:

HELPPPPP!!!!
Answer:
A recipe uses 250 mL of milk for every 300 g of flour.
For making a bigger batch using 600 g of flour, let the amount of milk be x mL.
Now we should solve for x
According to the above problem,

Step-by-step explanation:
SSS (Side-Side-Side) Postulate can be used to prove the two triangles congruent.
Here's why:
Whole figure is a parallelogram which means that opposite sides are parallel and equal (or congruent).
So, Two of the sides can be proved congruent by that way.
The third side is common in both of the triangles which means that the third side is also congruent.
Hence, the two triangles are congruent by SSS postulate.

Reflect this figure across the y-axis:
Answer:
The coordinates of the image triangle will be:
A'(-1, 1)B'(-1, 3)C'(-3, 3)Please also check the attached figure.
The green triangle represents the image triangle.
Step-by-step explanation:
We know that when we reflect a point across the y-axis, the y-coordinate remains the same but the x-coordinate reveres its sign.
Thus,
The rule of reflection of the point P(x, y) across the y-axis is:
P(x, y) → P'(-x, y)
In the attached figure, let the coordinates of the triangle are:
A(1, 1)B(1, 3)C(3, 3)Using the rule of reflection across the y-axis:
P(x, y) → P'(-x, y)
Thus, the coordinates of the image triangle will be:
A(1, 1) → A'(-1, 1)
B(1, 3) → B'(-1, 3)
C(3, 3) → C'(-3, 3)
Therefore, the coordinates of the image triangle will be:
A'(-1, 1)B'(-1, 3)C'(-3, 3)Please also check the attached figure.
The green triangle represents the image triangle.

The area of the figure is 45 sq.mi and the perimeter is 23.5354 mi.
What is Area ?Area is the space occupied by a two dimensional object,
The area and perimeter of the given shape can be determined by dividing it into basic shapes.
here, we have,
The area and the perimeter of the shape given
= Area of the rectangle +Area of upper triangle - Area of two small triangles at the bottom
Area of rectangle = 5 mi * 9 mi = 45 sq.mi
Area of upper Triangle = (1/2) *9*3 = 27/2 sq.mi
Area of small Triangle = (1/2) * 3*6 = 9 sq.mi
Area of other small Triangle = (1/2)*3*3 = 9/2 sq.mi
Area of the figure = 45 +13.5 -9-4.5
Area of the figure = 45 sq.mi
Similarly for Perimeter = Perimeter of the rectangle +Perimeter of upper triangle -Perimeter of two small triangles at the bottom
Perimeter = 28 -(3+6+6.708) -(3+3+4.2426) +(3+9+9.486
Perimeter = 23.5354 mi
Therefore , The area of the figure is 45 sq.mi and the perimeter is 23.5354 mi.

31. The director of a marketing department wants to estimate the proportion of people who purchase a certain product online. The director originally planned to obtain a random sample of 2.500 people who purchased the product. However, because of budget concerns, the sample site will be reduced to 1.500 people. Which of the following describes the effect of reducing the number of people in the sample? (A) The variance of the sample will increase
(B) The variance of the population will decrease.
(C) The variance of the sampling distribution of the estimator will increase
(D) The variance of the sampling distribution of the estimator will decrease
(E) The variance of the sampling distribution of the estimator will remain the same
Answer:
C
Step-by-step explanation:
AP Classroom says so
The correct option should be C: "The variance of the sampling distribution of the estimator will increase" because the sample size is decreased from 2500 to 1500.
Given information:
The director originally planned to obtain a random sample of 2500 people who purchased the product.
However, because of budget concerns, the sample size will be reduced to 1500 people.
Now, the variance of the sample distribution can be written as,
[tex]\dfrac{\sigma^2}{n}[/tex] where n is the sample size.
So, the variance is inversely proportional to the sample size.
Here, we can conclude that with an increase in sample size, the variance will decrease and vice versa.
Therefore, the correct option should be C: "The variance of the sampling distribution of the estimator will increase" because the sample size is decreased from 2500 to 1500.
