Answer:

The first one is B, the second is A

Step-by-step explanation:

For a polynomial to be in standard form, it needs to have the exponents decreasing from left to right. In order from left to right, B goes 7,3,2,1,0, hence it is in standard form.

A polynomial cannot have a fractional exponent, hence a is not a polynomial.

Answer: Male = 25

Female = 19

Step-by-step explanation:

Your question isn't complete. Let's form another identical question and solve.

A french class has a total of 44 students. The number of males is 6 more than the number of females. How many males and how many females are in the class?

Let the number of females be x

Therefore males = x + 6

Total students = 44

Therefore, x + x + 6 = 44

2x + 6= 44

2x = 44 - 6

2x = 38

x = 38/2 = 19

There are 19 females

Males = x + 6 = 19 + 6 = 25

Answer:

x= -7 and y=37

Step-by-step explanation:

substitute y=-26-9x in -2x-y=12

-2x-(-26-9x)=12

-2x+26+9x=12

-2x+9x=12-26

7x= -14

x= -14/2

x= -7

substitute x=-7 in y=26-9x

y= -26-9x

y= -26-9(-7)

y= -26+63

y=37

x= -7 and y=37

Answer:

There is 2 blue beads on Nicole's necklace.

Step-by-step explanation:

In order to find out how much blue beads Nicole has on his necklace we just have to multiply the total among of the bead on the necklace by the 10%.

20 x 10% = [tex](20) (\frac{1}{10} )[/tex] = [tex]2[/tex]

Answer:

The required equation is:

[tex]y = -\frac{3}{2}x+9[/tex]

Step-by-step explanation:

To find the equation of a line, the slope and y-intercept is required.

The slope can be found by finding the slope of given line segment. A the perpendicular bisector of a line is perpendicular to the given line, the product of their slopes will be -1 and it will pass through the mid-point of given line segment.

Given points are:

[tex](x_1,y_1) = (8,10)\\(x_2,y_2) = (-4,2)[/tex]

We will find the slope of given line segment first

[tex]m = \frac{y_2-y_1}{x_2-x_1}\\= \frac{2-10}{-4-8}\\=\frac{-8}{-12}\\=\frac{2}{3}[/tex]

Let m_1 be the slope of perpendicular bisector then,

[tex]m.m_1 = -1\\\frac{2}{3}.m_1 = -1\\m_1 = \frac{-3}{2}[/tex]

Now the mid-point

[tex](x,y) = (\frac{x_1+x_2}{2} , \frac{y_1+y_2}{2})\\= (\frac{8-4}{2} , \frac{10+2}{2})\\=(\frac{4}{2}, \frac{12}{2})\\=(2,6)[/tex]

We have to find equation of a line with slope -3/2 passing through (2,6)

The equation of line in slope-intercept form is given by:

[tex]y = m_1x+b[/tex]

Putting the value of slope

[tex]y= -\frac{3}{2}x+b[/tex]

Putting the point (2,6) to find the y-intercept

[tex]6 = -\frac{3}{2}(2)+b\\6 = -3+b\\b = 6+3 =9[/tex]

The equation is:

[tex]y = -\frac{3}{2}x+9[/tex]

The equation of the perpendicular bisection that passes through the point (2,6) and has a slope -3/2 is [tex]\rm (y-6)=-\dfrac{3}{2}(x-2)[/tex] and this can be determined by using the point-slope form of the line.

Given :

Endpoints  -- (8,10) and (-4,2)

The following steps can be used in order to determine the equation of the perpendicular bisector:

Step 1 - First, determine the slope of the line that passes through points (8,10) and (-4,2).

[tex]\rm m =\dfrac{2-10}{-4-8}[/tex]

[tex]\rm m = \dfrac{8}{12}[/tex]

[tex]\rm m = \dfrac{2}{3}[/tex]

Step 2 - So, the slope of the perpendicular bisector is given by:

[tex]\rm m'm = -1[/tex]

[tex]\rm m' = -\dfrac{3}{2}[/tex]

Step 3 - Now, determine the midpoint of the line that passes through the points (8,10) and (-4,2).

[tex]\rm x = \dfrac{8-4}{2}=2[/tex]

[tex]\rm y = \dfrac{10+2}{2}=6[/tex]

Step 4 - So, the equation of the perpendicular bisection that passes through the point (2,6) and has a slope -3/2 is:

[tex]\rm (y-6)=-\dfrac{3}{2}(x-2)[/tex]

Answer/Step-by-step explanation:

The interest rate is 15% for every 3 years. To find the interest rate subtract the money from the total. Then, divide the total from the difference. Now subtract the quotient from 100 and multiply it by 100 to fin the percentage.

3000 - 450 = 2550

2550 ÷ 3000 = 0.85

100 - 0.85 = 0.15

0.15 x 100 = 15%

Step-by-step explanation:

Let assume peter be

And, then mary is 2p ÷ 3

So

The equation would be  

2p ÷ 3  - 2 = 1 ÷ 2 (p + 5)

4p - 12 = 3p + 15

p = 27

So Peter age be 27
