Answer:

(7, 4)

Step-by-step explanation:

The rule to rotate a point/figure 90° clockwise about the origin is (x, y) -> (y, -x). We are given the point as (-4, 7).

Therefore, the answer is (7, 4).

Answer:

b. 6

Step-by-step explanation:

I'm not 100% sure if this is the answer but here was my thinking process:

1/4 of 24 is 6, and 6 + 3 is 9, so the brothers age is probably 9, and then 24-9 is 15, and the difference between 15 and 9 is 6. Once again I don't know if this is right or not, but either way I hope this helps!

Answer:

3 people

$9.5 left over

Step-by-step explanation:

pp = 18 + 22.75

pp = 40.75

total people who can go = 131.75/pp

tp = 131.75/pp

tp = 3 remainder $9.5

(this is if they all arrive in individual cars)

The number of people that can go to the amusement park are 5 .

First, we need to find the amount left after deducting parking charges. Then the remaining amount can be divided by the price of one ticket to find out how many persons can buy the ticket from the same amount.

Thus, 5 number of persons can go to the amusement park.

Answer:

29.6667%

Step-by-step explanation:

In first bag there is 15 M&M's ANd second bag has a total of 9 M&M's so that means there are a total of 24 M&M's.

In the first bag there is 5 blue M&M's and in the second bag there is a total of 2 blue M&M's so there is a total of 7 blue M&M's all together.

so there are 7/24 M&M's ( what were going to do it convert it into percents.

To do this were going to use these steps.

Calculations

7 divided by 24=0.291666.

Ok so now what is 0.291666 x 100=?

0.291666 x 100=29.6667 and there is our final answer.

Hope it helps have awesome day:)

Additional comment

Changing the sign of the x-coordinate moves a point horizontally to the other side of the y-axis, reflecting it over the y-axis.

Multiplying coordinate values by the same factor effects a dilation about the origin by that factor.

Adding to the x-coordinate moves the point to the right; adding to the y-coordinate moves the point up. (Subtracting from x moves the point left.)

Answer:

104/100

Step-by-step explanation:

The easiest way to do this problem is to convert the fraction 6/10 to have the same denominator as the other fractions, which in this case is ?/100.

we can convert 6/10 to have 100 as a denominator by multiplying the fraction by 10

[tex]\frac{6}{10} *10=\frac{60}{100}[/tex]

now we can just add the fractions together!

[tex]\frac{17}{100} +\frac{17}{100} +\frac{60}{100} =\frac{104}{100}[/tex]

Answer:

Point slope form of the equations:

y = -3x + 8

y = 2x - 2

Solution to the system of equations:

(x, y) ==> (2, 4)

Step-by-step explanation:

6x + 2y = 16

2x - y = 2

6x + 2y = 16

2(2x - y = 2)  ==> 4x - 2y = 4

6x + 2y = 16

4x - 2y = 4

10x = 20

/10     /10

x = 2

Now, we solve for y:

6x + 2y = 16

6(2) + 2y = 16

12 + 2y = 16

-12         -12

2y = 4

/2   /2

y = 2

(x, y) ==> (2, 2)

Point-slope forms:

6x + 2y = 16

-6x          -6x

2y = -6x + 16

/2        /2

y = -3x + 8

2x - y = 2

-2x      -2x

-1y = -2x + 2

/-1       -1

y = 2x - 2

Given that the parent function, y = x², has a leading coefficient of 1, the

following are the comparisons of the equations with the parent functions;

[tex]\begin{array}{|c|cc|}Steeper \, than \, y = x^2&&Less \, Steep \ than \, y = x^2 \\y = 2 \cdot x^2&&y = \frac{1}{2} \cdot x^2 \\y = \left(2 \cdot x \right)^2&&y = \left(\frac{1}{2} \cdot x \right)^2 \end{array}\right][/tex]

The parent function is y = x²

The leading coefficient of the parent function = 1

The steepness of a quadratic equation is given by the value of the

leading coefficient.

When the leading coefficient is larger than 1, we have;

The function is steeper than y = x²

When the leading coefficient is a fraction larger than 0 but lesser than 1, we have;

The function is less steep than y = x²

Which gives;

[tex]\begin{array}{|c|cc|}Steeper \, than \, y = x^2&&Less \, Steep \ than \, y = x^2 \\y = 2 \cdot x^2&&y = \frac{1}{2} \cdot x^2 \\y = \left(2 \cdot x \right)^2&&y = \left(\frac{1}{2} \cdot x \right)^2 \end{array}\right][/tex]

The function y = -x² is inverted has the same steepness as y = x², but will not be used.

The value of c for a standard normal distribution, P(z < c) = 0. 3387 is -0.41.

Z score is used to determine by how many standard deviations the raw score is above or below the mean. It is given by:

z = (x - μ)/σ

Where x is the raw score, μ is the mean and σ is the standard deviation.

Given that P(z < c) = 0. 3387; hence:

From the normal distribution table, c = -0.41

Answer:

1080

Step-by-step explanation:

The unit rate per hour is 120 and you drove for 9 hours so to find the answer you should use the equation:

120h=total kilometers driven

the number of hours is 9 so, you would subsitute that for the variable to get:

120x9=1080

Divide miles traveled by percentage.

666/0.74 = 900

total length is 900 miles

Answer:

This equation cannot be solved to find the correct width of the rectangle because the formula for the area of a rectangle is area = base times the height. Therefore, you can't just simply subtract 9 from 48 to get the width. Instead, you have to divide 48 by 9 to find the width, since 48 is the area and 9 is the length.

|x+120|

|x+120| = x+120 for (x+120)>=0 and|x+120| = -(x+120) for (x+120)<0

Answer:

The first, third, andd sixth choice is correct.

Step-by-step explanation:

The y-intercept is when x = 0.

So if we plug x = 0 into the equation.

y = -4(0) + 98

y = 98

So the first choice is correct.

y = mx + b

y = -4x + 98

m = slope

b = y-intercept

So, the slope must mean it's decreasing.

So the third choice is correct.

Let try plugging in values for x.

y= -4(0) + 98 = 98

y= -4(1) + 98 = 94

y= -4(2) + 98 = 90

x stands for the number of days the students miss.

We see the bigger the value we put in for x, the lower the test score is aas represented by y.

So, the sixth choice is correct.

we know that,

y intercept exist when x = 0

so,

⇢y = -4x +98

⇢y = -4 x 0 +98

⇢y = 98

so , the expected test score is 98

when x = 0

y = -4(0) +98

when x = 1

y= -4(1) +98 = 94

when x = 2

y= -4(2) +98 = 90

we can see the decresement of 4 points

We can see that the increament in absent days lead to lower scores ( one class = 4 points)

Answer:

7.5

Step-by-step explanation:

Ok so this is how I got it:

Since we know the lengths of sides NO, MN, and JK, but we don't know the length of KL, we can use what we know.

To get from MN to JK, we multiply MN (2) by 1.5 to get 3. So you can go the same thing to get from NO to KL.

Just go ahead and multiply 5 by 1.5

5 × 1.5 = 7.5

Hope this helps!

Answer:

KL = 7.5

Step-by-step explanation:

MN : JK = NO : KL

⇒ 2 : 3 = 5 : KL

[tex]\implies \dfrac23=\dfrac{5}{KL}[/tex]

⇒ 2 · KL = 5 · 3

⇒ 2(KL) = 15

⇒ KL = 15 ÷ 2

⇒ KL = 7.5

Answer:

Measure all sides of the triangle (all 3 sides), and depending on the lengths see if they are all equal, if two are equal, or if there are no equal sides at all. If there are all equal side lengths you have an equilateral triangle that has 3 congruent, aka equal sides.

If two angles and the included side of one triangel are equal to the corresponding angel and the side of another triangel, the triangles are congurent.
