Which systems have infinite solutions? Check all that apply. y = 0.5x + 2.75 and 2y = x + 2.75 y = 0.5x + 2.75 and y – 0.5x = 2.75 y = 0.5x + 2.75 and 0.5x + y = 2.75 y = 0.5x + 2.75 and y = 0.5(x + 5.5) y = 0.5x + 2.75 and y = –2(–0.25x )+ 2.75

Answers

Answer 1

Answer:

Three solutions

Step-by-step explanation:

Infinite solutions means each and every point satisfies both the equations which means there would be a graph that overlaps the original graph.

So compare the equations with the equation

y = 0.5x + 2.75

each and every equation in this form has infinitely many solutions like

y = 0.5x + 2.75 and y - 0.5x = 2.75 these both equations are same. So they have infinitely many solutions as they overlap each other. Furthermore

y = 0.5x + 2.75 and y = 0.5(x + 5.5)

y = 0.5x + 2.75 and y = –2(–0.25x )+ 2.75

all these 4 equations are the same which is y = 0.5x + 2.75 so three systems have infinite solutions we can confirm this by using the desmos online graphing calculator just insert these equations into it and you will see all these equations are the same just like  for example

y = 2x and 2y = 4x

There exists a similarity transformation that maps AABC to AA'B'C'. The measure
of ZAis 68°, and the measure of ZBis 46°. What is the measure of ZC'in
degrees?

Answers

Answer:

∠C' = 66°

Step-by-step explanation:

Because triangles ABC and A'B'C' are similar, their angles are still the same; only their side lengths are different, though still proportionate.

Hence, ∠A = ∠A', ∠B = ∠B', and ∠C = ∠C'.

Here, we're given that ∠A = 68, which means ∠A' = 68; we also know that ∠B = 46, so ∠B' = 46.

We want to find C', so remember that all angles in a triangle sum to 180:

∠A' + ∠B' + ∠C' = 180

68 + 46 + ∠C' = 180

114 + ∠C' = 180

∠C' = 66°

Answer:

∠C' = 66°

Step-by-step explanation:

∠A' + ∠B' + ∠C' = 180

68 + 46 + ∠C' = 180

114 + ∠C' = 180

∠C' = 66°

Replace 5 with 1. Now you have 1, 2, 3: mean is 2.

In this case, it affected the mean.

Example B.

2, 3, 5: mean is 3

Replace 5 with 4. Now you have 2, 3, 4: mean is 3.

In this case, it did not affect the mean.

As you can see, replacing the maximum value of the data set with a smaller number may or may not change the mean.

two students have examined the scatter plot shown in have created in line best fit for the data. student A believes that the line of best fit for the data is y= -2x + 24, while student B believes that the line of best fit for the data is y = 1.5 + 23
*Determine which student created a better line of best fit given the data in the graph. ​

Answers

Answer:

Step-by-step explanation:

im pretty sure its student a not 100% sure tho

The line of best fit is simply the trending line of a graph

Student A creates a better line of best fit

The linear equations are given as:

[tex]\mathbf{y = -2x + 24}[/tex]

[tex]\mathbf{y =1.5x + 23}[/tex]

The given graph shows a negative linear association.

This is so because, as the x-values increases, the y-values decreases.

This in other words means that:

The slope of the graph is negative

A linear graph is represented as:

[tex]\mathbf{y = mx + c}[/tex]

Where: m represents slope

By comparison

m = -2 and m = 1.5 for the equations of the two students.

Because the slope of the graph is negative, then

m =-2 is correct

Hence, student A creates a better line of best fit

Consider that a population of fruit flies grew in a 40-day experiment. Average rate of change: 9 flies/day. Find the average growth rate from day 30 to day05​

Answers

Answer: Average Growth Rate is 24.19%

Step-by-step explanation:

Given that;

Average rate of change = 9 flies/day

Average growth rate of change = ?

we can determine the average growth rate of change from the expression;

Average Annual Growth Rate = [((Present Value - Past Value)^1/N) - 1 ]  × 100%]

Now our present value; 30th day = 9 × 30 = 270

past value; 05th day = 9 × 05 = 45

the value of N = 30 - 5 = 25

so we substitute

Average Annual Growth Rate = [((270 - 45)^1/25) - 1 ]  × 100%]

=  ([1.2419 - 1) × 100]

= 24.19%

Therefore Average Growth Rate is 24.19%

Justin needs to make 80 illustrations for an art book. He has made 40% of the illustrations. How many illustrations does he still need to make?

Answers

First we should work out what 40% is in decimal form.

We can do this by doing 40 divided by 100 which gives us: 0.40

Therefore 40% in decimal form is 0.40.

Next we do 80 x 0.40 which gives us 32, this means Justin has already made 32 illustrations.


Next we do 80 - 32 which gives us 48, this means Justin still has to do 48 illustrations.


I hope this helps!

During a flu epidemic the number of sick people triples every week what is the growth rate as a percent ?

Answers

Answer:

2 or 200%

Step-by-step explanation:If the growth rate doubled every week, it would grow by 100% per week. Since the growth rate triples every week, it grows by 200% per week. This is easy to see..... If 1 person is sick at the start.......by the end of the first week, 2 more would be sick. And 2 is 200% of 1. So, 3 people are sick at the end of the first week- triple that of the start. At the end of the second week,  6 more would be sick , and 6 is 200% of 3. So, 9 people total are sick at the end of the second week - triple that of the beginning of the second week
