How many students are in Ms. Jackson’s class?

From the question, we have the following parameters that can be used in our computation:

The Venn diagram

Where, we have

Both = 5

None = 2

Using the above as a guide, we have the following:

Total students = (10 -5) + 5 + (8 -5) + 2

Evaluate

Total students = 15

Hence. there are 15 students in Ms. Jackson’s class

Answer:

C)x^2 - 6x-6

Step-by-step explanation:

-3(x + 2) + (x – 3)x=

-3x-6+x^2-3x=

x^2 - 6x-6

Answer:

C

Step-by-step explanation:

-3(x + 2) + (x – 3)x = -3*x + (-3)*2 +x*x - 3*x

                              = -3x - 6  +x² - 3x

                              = x² - 3x -3x - 6

                               = x² - 6x - 6

Answer:

The other x-intercept is the point (1,0)

Step-by-step explanation:

we have

[tex]y=x^2-3x+2[/tex]

The formula to solve a quadratic equation of the form

[tex]ax^{2} +bx+c=0[/tex]

is equal to

[tex]x=\frac{-b\pm\sqrt{b^{2}-4ac}} {2a}[/tex]

in this problem we have

[tex]y=x^2-3x+2[/tex]

equate to zero

[tex]x^2-3x+2=0[/tex]

so

[tex]a=1\\b=-3\\c=2[/tex]

substitute in the formula

[tex]x=\frac{-(-3)\pm\sqrt{-3^{2}-4(1)(2)}} {2(1)}[/tex]

[tex]x=\frac{3\pm\sqrt{1}} {2}[/tex]

[tex]x=\frac{3\pm1} {2}[/tex]

so

[tex]x=\frac{3+1} {2}=2[/tex]

[tex]x=\frac{3-1} {2}=1[/tex]

therefore

The other x-intercept is the point (1,0)

Step-by-step explanation:

Let the required line bisects the segment joining the point (5,3) and (4,4) at point M (x, y).

Therefore, M is the mid point of segment joining the point (5,3) and (4,4).

Now by mid-point formula we have:

[tex]M = ( \frac{5 + 4}{2} \: \: \frac{3 + 4}{2} ) = ( \frac{9}{2} \: \: \frac{7}{2} ) \\ \\ \therefore \: M \: = ( 4.5 \: \: 3.5 ) = (x_1 \: \: y_1)\\ \\ \because \: Line \: makes \: 45 \degree \: angle \: with \: positive \: \\ \: \: \: \: \: direction \: of \: x - axis. \\ \\ \therefore \: Slope \: of \: line: \: \\ \: \: \: \: \: \: \: m = tan \: 45 \degree = 1 \\ \\ Equation \: of \: line \: in \: slope \: point \: form\\ \: is \: given \: as: \\ y-y_1 =m(x-x_1) \\ \therefore \: y - 3.5 = 1(x - 4.5) \\ \therefore \: y - 3.5 = x - 4.5 \\ \therefore \: y = x - 4.5 + 3.5 \\ \therefore \: y = x - 1\\ \huge \purple { \boxed{\therefore \: x - y - 1 = 0}} \\ [/tex]

is the equation of required line.

Answer:

Slope=2/4 or 1/2

Y-Intercept=8

Step-by-step explanation:

-2x+4y=8

+2x both sides

4y=2x+8

/4

y=2/4x+8

Slope=2/4 or 1/2

Y-Intercept=8

The slope of the graph of the equation -2x + 4y = 8 is  [tex]\frac{1}{2}[/tex] , and the

y-intercept is 2.

To calculate the y-intercept and slope of the graph of the equation -2x + 4y = 8, to change the given equation in the general form of line. The general form of the line is y = mx + b, where m is the slope of the line and b is the y-intercept of the line.

Find the value of y from the given equation of graph.

Calculate y as:

[tex]-2x + 4y = 8\\4y = 2x + 8\\y=\dfrac{2}{4}x+2\\ y=\dfrac{1}{2}x +2[/tex]

Here, the slop of the graph m is  [tex]\dfrac{1}{2}[/tex]  and  y-intercept is 2

Therefore, the slope of the graph is 1/2, and the y-intercept is 2.

Answer:

17.861 feet or 17.9 feet (3 sf)

Step-by-step explanation:

180 - 36 - 87 = 57

X/sin(87) = 15/sin(57)

X = 17.861 feet

There are 15 girls and 18 boys. Therefore, the ratio of girls to boys in the cafeteria is 15 : 18 (or 15/18). However, both sides can be divided by 3, which simplifies the ratio to 5 : 6 (or 5/6).

Hope this helps!! :)

Answer: The ratio would be 5 girls to every 6 boys.

Step-by-step explanation:

Find a common number both can be divided be which would be 3, so 15 by 3 is 5, and 18 by 3 is 6. So, there is 5 girls for every 6 boys which is the ratio.

Answer:

Step-by-step explanation:

Answer:

c = 57.5

Step-by-step explanation:

Since its 90 degree.

it would be 90 - 32.5 = c

Answer:

57.5

Step-by-step explanation:

It’s a 90 degree angle, which means the angles added together make 90. So if you want to get the missing angle, subtract the 32.5 angle to see what remains. That is your missing angle

Option C:

[tex]2 g^{3}-5 g^{2}+6[/tex]

Solution:

Given expression:

[tex]$\frac{\left(5 g^{4}+5 g^{3}-17 g^{2}+6 g\right)-\left(3 g^{4}+6 g^{3}-7 g^{2}-12\right)}{g+2}[/tex]

To find which expression is equal to the given expression.

[tex]$\frac{\left(5 g^{4}+5 g^{3}-17 g^{2}+6 g\right)-\left(3 g^{4}+6 g^{3}-7 g^{2}-12\right)}{g+2}[/tex]

Expand the term [tex]-\left(3 g^{4}+6 g^{3}-7 g^{2}-12\right):-3 g^{4}-6 g^{3}+7 g^{2}+12[/tex]

         [tex]$=\frac{5 g^{4}+5 g^{3}-17 g^{2}+6 g- 3 g^{4}-6 g^{3}+7 g^{2}+12}{g+2}[/tex]

Arrange the like terms together.

         [tex]$=\frac{5 g^{4}- 3 g^{4}+5 g^{3}-6 g^{3}-17 g^{2}+7 g^{2}+6 g+12}{g+2}[/tex]

         [tex]$=\frac{2 g^{4}- g^{3}-10 g^{2}+6 g+12}{g+2}[/tex]

Factor the numerator [tex]2 g^{4}-g^{3}-10 g^{2}+6 g+12=(g+2)\left(2 g^{3}-5 g^{2}+6\right)[/tex]

         [tex]$=\frac{(g+2)\left(2 g^{3}-5 g^{2}+6\right)}{g+2}[/tex]

Cancel the common factor g + 2, we get

Answer: About 4 movies

Step-by-step explanation:

1 2/3 times 4/1 = 28/5

28/5 converted to a mixed number is 5 3/5

so therefore it would be ABOUT 4 movies

To find the number of movies that can be downloaded, divide the total downloading time by the time it takes to download one movie. In this case, 15 movies can be downloaded.

To find the number of movies that can be downloaded, we need to divide the total downloading time by the time it takes to download one movie. First, convert the mixed number 5 1/4 to an improper fraction, which is 21/4. Then, multiply 21/4 by the reciprocal of 1 2/5, which is 5/7. This gives us a total of 15 movies that can be downloaded.

Each point is placed in a quadrant based on its x and y values. Quadrant I contains points where both values are positive, Quadrant II where x is negative and y is positive, Quadrant III where both are negative and Quadrant IV where x is positive and y is negative

To determine which quadrant a point is located in, recognize that the x-y coordinate plane is divided into four sections called quadrants. The quadrants are numbered I through IV and progress counterclockwise, starting with quadrant I in the upper right corner.

Quadrant I: Both x and y are positive. Quadrant II: x is negative, y is positive. Quadrant III: Both x and y are negative. Quadrant IV: x is positive, y is negative.

Each jar will have approximately [tex]\( \boxd{2.111 \text{ gallons}} \)[/tex] of honey.

Step 1

To find out how much honey will be in each jar when Jill distributes all of the honey equally among 9 jars, we need to divide the total amount of honey by the number of jars.

Given:

Total amount of honey = 19 gallons

Number of jars = 9

So, to find out how much honey each jar will have, we divide the total amount of honey by the number of jars:

[tex]\[ \text{Amount of honey per jar} = \frac{\text{Total amount of honey}}{\text{Number of jars}} \]\[ \text{Amount of honey per jar} = \frac{19 \text{ gallons}}{9} \]\[ \text{Amount of honey per jar} = \frac{19}{9} \text{ gallons} \][/tex]

Step 2

Now, let's perform the division:

[tex]\[ \text{Amount of honey per jar} = 2.111111 \text{ gallons} \][/tex]

So, each jar will have approximately [tex]\( \boxd{2.111 \text{ gallons}} \)[/tex] of honey.

Supplement of an angle measuring 50 degrees is 130 degrees

Step-by-step explanation:

Step 1 :

Given,

Measure of the angle = 50 °

We need to calculate the supplement of this angle

Step 2 :

2 angles are supplement to each other if the sum of their measures is 180°.

Hence the supplement of one angle can be computed by subtracting the value of that angle from 180°

Hence the supplementary angle to 50 ° is 180° - 50 ° = 130 °

We have to find the vertex and axis of symmetry

The general equation is given as:

[tex]f(x) = ax^2 + bx + c[/tex]

Comparing with given equation,

a = 2

b = 0

c = -1

The axis of symmetry is given as:

[tex]x = \frac{-b}{2a}[/tex]

[tex]x = \frac{0}{2(2)}\\\\x = 0[/tex]

Thus axis of symmetry is 0

The x coordinate of the vertex is the same

x coordinate of the vertex = 0

h = 0

The y coordinate of the vertex is:

k = f(h)

k = f(0)

[tex]f(0) = 2(0) - 1\\\\f(0) = 0 - 1\\\\f(0) = -1[/tex]

Thus, y coordinate of the vertex is -1

Therefore, vertex is (0, -1)
