Answer:

-2x + 85 = 5x - 48

85 = 7x - 48

7x = 133

x = 19

BC = -2(19) + 85

BC = -38 + 85

therefore, BC = 47

Macy didnt correctly find the equivalent fraction with the denominator of 30

4/5 is 24/30 not 18/30.

this is because 4×6 is 24 which is the numerator and 5×6 is 30 which is the denominator

Answer:

Macy did not correctly find the equivalent fraction with the denominator of 30.

Step-by-step explanation:

What Macy should have written:

[tex]\frac{4}{5} ?\frac{18}{30} =\\\\\frac{24}{30} >\frac{18}{30}[/tex]

What Macy wrote:

[tex]\frac{4}{5} ?\frac{18}{30} =\\\\\frac{18}{30} <\frac{19}{30}[/tex]

[tex]\frac{4*6}{5*6}[/tex] does not equal [tex]\frac{18}{30}[/tex]

Answer:

B) (g+4)(g+10)

EDGE 2020

The area of the planned school garden have dimensions of g + 4 and g + 10 respectively.

An equation is an expression that shows the relationship between two or more variables and numbers.

Given the area of the planned school garden as:

A = g² + 14g + 40

A = g² + 10g + 4g + 40 = g(g + 10) + 4(g + 10)

A = (g + 4)(g + 10)

The area of the planned school garden have dimensions of g + 4 and g + 10 respectively.

Answer:

A. 0

E. -3

F. 9

Step-by-step explanation:

You can't divide by 0; it is undefined. So if x cannot equal zero, then anything that turns the denominator to zero is an asymptote. Therefore, the roots of the cubic expression would be excluded, and we get our final answers.

Answer:

A reflection across the y axis

Step-by-step explanation:

think about it, if you reflect some point across the y-axis it will have a negative x value.  For example, if you reflect (1,2) across the y-axis you will get (-1,2)

Answer:

This type of transformation is called mirroring in the y-axis.

Step-by-step explanation:

By mirroring in the y-axis, you can find the new value, by multiplying the x-coordinate by -1.

Any point (a , b) will be transformed after mirroring in the y-axis, to (-a , b), which is the question here.

This type of transformation is called mirroring in the y-axis.

Step-by-step explanation:

all coplanar points equidistant from a given point = circle

two rays with a common endpoint = angle

piece of a line with two endpoints = line segment

piece of a line with one endpoint = ray

The correct matching is given below.

One mathematical model makes up a term.

It is the close curve of an equidistant point drawn from the center.

A line segment is sometimes referred to as a section of a path that joins two places.

The angle is the distance between the intersecting lines or surfaces.

Step-by-step explanation:

Answer:

2n and 2n+2 are two consecutive even numbers, then the difference of their squares is:

As we see it is multiple of 4.

We have 8/27 which can be written as (2/3)^3, so 8/27 is a perfect cube.

Similarly, 125/64 = (5/4)^3, showing that it too is a perfect cube. So far we have eliminated choices A and B.

Choice C is also eliminated because -64 = (-4)^3

Lastly, choice D is not a perfect cube assuming it is 136 because 136^(1/3) = 5.142563 is not rational (ie not a fraction of whole numbers). The same can be said about 1/36 and 13/6 as well.

Answer:

Step-by-step explanation:

We will use 2 coordinates from the table along with the standard form for an exponential function to write the equation that models that data. The standard form for an exponential function is

[tex]y=a(b)^x[/tex] where x and y are coordinates from the table, a is the initial value, and b is the growth/decay rate. I will use the first 2 coordinates from the table: (0, 3) and (1, 1.5)

Solving first for a:

[tex]3=a(b)^0[/tex]. Sine anything in the world raised to a power of 0 is 1, we can determine that

a = 3. Using that value along with the x and y from the second coordinate I chose, I can then solve for b:

[tex]1.5=3(b)^1[/tex]. Since b to the first is just b:

1.5 = 3b so

b = .5

Filling in our model:

[tex]y=3(\frac{1}{2})^x[/tex]

Since the value for b is greater than 0 but less than 1 (in other words a fraction smaller than 1), this table represents a decay function.
