Explanation and Answer:

The graph of y=[tex]x^2[/tex] is a parabola (it looks like a u) that intersects the graph at the origin. These are all shifted variations of that graph, so from that you can figure out their formula by visualizing it.

You can also try substituting numbers into the equations and drawing a graph from that.

Graph A is the y=x^2, shifted to the left, so it becomes [tex]y=x^2+x[/tex]. It's +x because now negative numbers can be gotten from the equation, as compared to before when x^2 gives only positive numbers.

Graph B is [tex]y=x^2+3x[/tex] . Similar to graph A, but now it moves down by more units, because of the 3x.

Graph C is [tex]y=-x^2+2[/tex]. Imaging y=x^2 flipped, it changes from looking like a u to n. That's y=[tex]-x^2[/tex]

Graph D is [tex]y= x^2-x[/tex]. The opposite of Graph A.

Answer:

y=x+1.75

4x-2y = 4

The answer is (3. 75, 5.5)

Step-by-step explanation:

If you plot the two equations on Desmos' Graphing Calculator, you will see that the solution is intersected at (3.75, 5.5).

The sample space of Shari's tree diagram is the total possible outcomes of rolling the game piece and spinning the pointer.

It doesn't matter if Shari starts with the spinner or the game piece

The experiment involves:

If Shari starts with the game piece, the sample size (n) would be:

n = 12 * 4

n = 48

If Shari starts with the spinner, the sample size (n) would be:

n = 4 * 12

n = 48

Notice that the sample size remains unchanged irrespective of what he starts with

Hence, it doesn't matter if Shari starts with the spinner or the game piece

The possible outcomes of the fair coin and the dice is the sample space

The items are given as:

Coin = 1

Dice = 1

The sample space of both items are:

Coin = {H,T}
Dice = {1,2,3,4,5,6}

So, the list of possible outcomes is: {H1,H2,H3,H4,H5,H6,T1,T2,T3,T4,T5,T6}

From the above list, there is only one outcome that has a head and a 3 out of 12 possible outcomes

So, the probability of getting a head and a 3 is:

p = 1/12

Hence, the probability of getting a head and a 3 is 1/12

Answer:

A

Step-by-step explanation:

3x and x + 30 are vertically opposite angles and are congruent , then

3x = x + 30 ( subtract x from both sides )

2x = 30 ( divide both sides by 2 )

x = 15

Then

∠ A = 3x = 3(15) = 45°

See <A and x+30 are opposite angles .

We know that opposite angles are equal

The largeness of the circle is an illustration of proportions

Using the assumed parameters, the circle must be 200 times larger than a normal circle

The question is incomplete; so I will make use of assumed values

Assume that a normal circle of radius r can take up to 50 toy cars.

When the normal circle is replaced by a larger circle of radius R to take up to 10000 toy cars, the size of the circle must be:

Size = 10000/50

Divide

Size = 200

This means that the circle must be 200 times larger than a normal circle

Answer:

$43.55

Step-by-step explanation:

I took 65 and found 33% by making 33% .33 and did 65*33, then subtracted what I got from the total of 65, 65-21.45 which is $43.55.

Answer:

25%

Step-by-step explanation:

Given the following question:

What percent is 10 out of 40?

We use the formula to calculate percentages to find the answer.

[tex]\frac{p \times n}{100}[/tex]
[tex]\frac{25\times40}{100} =25\times40=1000\div100=10[/tex]

12% of the people surveyed own fish.

Relative frequency refers to the percentage or proportion of times that a given value occurs within a set of numbers, such as in the data recorded for a variable in a survey data set.

We get  

Total (own fish) = 0.04 + 0.08 = 0.12

So, own fish = 0.12

= 12%

If the initial population of the bacteria is 100, then the population of the bacteria after 180 hours will be 800.

Exponential notation is the form of mathematical shorthand which allows us to write complicated expressions more succinctly. An exponent is a number or letter is called the base. It indicates that the base is to raise to a certain power. X is the base and n is the power.

A colony of 100 bacteria doubles in size every 60 hours.

The exponential relation will be given below.

[tex]\rm P = 100 \times 2^{t/60}[/tex]

Where t is the number of hours

Then the population of the bacteria after 180 hours will be

[tex]\rm P = 100 \times 2^{t/60} \\\\P = 100 \times 2 ^{180/60}\\\\\rm P = 100 \times 2^{3}\\\\\rm P = 100 \times 8\\\\\rm P = 800[/tex]

The order of the expression for congruent shapes indicate the

corresponding vertices between the two shapes that are congruent.

The option which is true is D. T = Q.

Reasons:

The given statement is; ΔRST ≅ ΔNPQ

By Corresponding Parts of Congruent Triangle are Congruent, CPCTC, we

have; The sides on ΔRST are congruent to the corresponding sides of ΔNPQ

Therefore;

RS ≅ NP

RT ≅ NQ

ST ≅ PQ

By CPCTC, we have that the angles on ΔRST are congruent to the corresponding angles of ΔNPQ

Therefore;

∠R ≅ ∠N

∠S ≅ ∠P

∠T ≅ ∠Q

Which gives, by definition of congruency;

∠R = ∠N

∠S = ∠P

∠T = ∠Q

Therefore, the true statement is D. T = Q.

Answer:

"Two complex solutions" is the answer.

Answer:

Two complex solutions.

Step-by-step explanation:

Length = L

Width = W

L=8 more than 2W

L = 8 * 2W

L = 16W

Perimeter = 96

perimeter is the lengths of all sides added together

so

2L + 2W = 96

we have

L = 16W

2L + 2W = 96

let's do substitution

put what L = into 2L + 2W = 96

so

2(16W) + 2W = 96

can you rearrange that to get w
