Which of the following functions best describes this graph?
A. y = (x-1)(x+3)
B. y =x^2-x+5
C. y = (x+1)(x+1)
D. y=x^2-5x+6​

Answer:

The figure would move 2 units to the left and 4 units up and the image would be congruent.

Step-by-step explanation:

If you transformed a figure using the rule (x-2, y+4).

Then the figure would move 2 units to the left (x-2) and 4 units up (x+4).

Similar figures would have the same shapes but different sizes.

Congruent figures would have the same shapes and same sizes but might be rotated.

Figures can not be both similar and congruent.

Moving the whole shape will not change the size; therefore, the figures would be congruent.

Answer:

intersecting lines will cross at the point

Answer:

The probability that there is at least one pair but not a three of a kind is 0.6944.

Step-by-step explanation:

We have the case when we have five dices and we roll them and we need  that there is at least one pair but not a three of a king which is Two dice showing the same value, but no three dice showing the value.

Total no of outcomes = [tex]6^5 = 7776[/tex]

We will consider the other cases and then subtract them from the total outcomes.

No of outcomes of 5 of a kind = 6

No of outcomes 4 of a kind and 1 different = (6*5)*5 = 150

No of outcomes with 3 of a kind and 1 different pairs = (6*1*1*5*1)*5C2= 300

No of outcomes with 3 of a kind and two different = 6*5*4*10= 120*10=1200

No of outcomes when all are different = 6! = 720

These all the cases when subtracted from the total will represent the total cases in which there are two dice showing the same value.

Total cases = 6+150+300+1200+720

                   = 2376

Required no of outcomes = 7776-2376 = 5400

Probability = [tex]\frac{5400}{7776}[/tex] = 0.6944

Therefore the probability for the case of at least one pair but not a three of a kind is 0.6944.

Answer: A. -0.25

Hope it helps :)

Step-by-step explanation:

So since 0.75 and -1.25 are in parenthesis, u have to multiply them.

-1 (0.75 - 1.25) = 0.5

-3/4 - 0.5 = -0.25

So the answer is -0.25

Answer:

A = 7t + 100 and C = 10t+55 are the equations for each situation and they both will have an amount of $205 after 15 weeks.

Step-by-step explanation:

Given that:

Alyssa started savings with $100

Saved amount each week = $7

A = Amount of money Alyssa have

t = number of weeks

A = 7t + 100

Colton started savings with $55

Saved amount each week = $10

C = 10t + 55

For same amount;

A = C

7t+100 = 10t+55

100-55=10t-7t

45=3t

3t=45

Dividing both sides by 3

[tex]\frac{3t}{3}=\frac{45}{3}\\t=15[/tex]

Putting t=15 in Alyssa's equation

A = 7(15)+100

A = 105+100 = $205

Hence,

A = 7t + 100 and C = 10t+55 are the equations for each situation and they both will have an amount of $205 after 15 weeks.

The solution is,  14.6° is the angle of elevation of a hill whose slope has a length of 345 feet and rises 87 feet.

Trigonometry is the study of the relationships between the angles and the lengths of the sides of triangles

here, we have,

The six trigonometric functions are sin , cos , tan , cosec , sec and cot

Let the angle be θ , such that

sin θ = opposite / hypotenuse

cos θ = adjacent / hypotenuse

tan θ = opposite / adjacent

here, we have,

given that,

a hill whose slope has a length of 345 feet and rises 87 feet

now, we have to find the angle of elevation of a hill.

so, we get,

perpendicular = 87

hypotenuse = 345

let, the angle of elevation is θ.

we have,

sin θ = 87/345

so, we get,

θ = 14.6°

Hence, The solution is,  14.6° is the angle of elevation of a hill whose slope has a length of 345 feet and rises 87 feet.

Step-by-step explanation:

Writing an expression for the perimeter (P) of the triangle

P = x - 4.5 + x - 4.5 + x - 4.5 ← as a sum

P = 3(x - 4.5) ← as a product

Answer:

the price that Michael charge per pack is $16.01

Step-by-step explanation:

The computation of the price that Michael charge per pack is as follows:

= 124 sports card ÷ 4 cards

= 31 packs

Now the charge per pack would be

= $496.31 ÷ 31 packs

= $16.01

hence, the price that Michael charge per pack is $16.01

The same is to be considered

Answer:

The percentage of people who are satisfied with this car model is 30%.

Step-by-step explanation:

Given that the survey interviewed 1,900 people who own a certain type of car, and of them 570 said that they would buy the same car model again, to determine the percentage of people who are satisfied with that model it is necessary to perform the following calculation :

1,900 = 100

570 = X

((570 x 100) / 1,900) = X

57,000 / 1,900 = X

30 = X

Therefore, the percentage of people who are satisfied with this car model is 30%.

Answer:

30

Step-by-step explanation:

Given

ab=5

a²+b²=25

So

(a+b)²=a²+ab+b²

=a²+b²+ab

=25+5

=30

Answer:

(a + b)² = 35

Step-by-step explanation:

Note the expansion of (a + b)²

(a + b)² = a² + b² + 2ab ← substitute given values

            = 25 + 2(5)

            = 25 + 10

            = 35

Find an ordered pair to represent in the equation vec t = 4 vec u +6 vec v where vec u =(-1,4) and vec v = (3,-2)

Substitute the given vector into the expression for vec t.

Recall that: vec t = 4 vec u +6 vec v

vec t = 4(-1,4)+6(3,-2)

vec t = (4(-1), 4(4)) + (6(3), 6(-2))

vec t = (-4, 16) + (18, -12)

vec t = (-4+18, 16+(-12))

vec t = (14, 16-12)

vec t = (14, 4)

Hence an ordered pair to represent vec t in the equation is (14, 4)

Note that the vec v was assumed. Any other vector coordinate can also be used

Answer:

[tex]\frac{2}{3}[/tex]

Step-by-step explanation:

To find the slope of a line, we would need to use the equation [tex]\frac{y_2-y_1}{x_2-x_1}[/tex] where two given points are [tex](x_1, y_1)[/tex] and [tex](x_2, y_2)[/tex]. These points can be any two points that fall on the line.

In the graph, two points we can use to find the slope is (1, 2) and (-2, 0).

[tex]\frac{y_2-y_1}{x_2-x_1}\\\\\frac{0-2}{-2-1} \\= \frac{-2}{-3} \\= \frac{2}{3}[/tex]

Therefore, the slope of the line is [tex]\frac{2}{3}[/tex].

Answer:

c

Step-by-step explanation:

Given the2 equations

y = x + 4 → (1)

x + y = 2 → (2)

Substitute y = x + 4 into (2)

x+ x + 4 = 2

2x + 4 = 2 ( subtract 4 from both sides )

2x = - 2 ( divide both sides by 2 )

x = - 1

Substitute x = - 1 into (1) for corresponding value of y

y = - 1 + 4 = 3

solution is (- 1, 3 ) → c
