Answer:

B

Step-by-step explanation:

The value of expression 34 + 4/9 w at w = -1/2 is [tex]33\frac{7}{9}[/tex]

The definition of an expression in maths is a statement composed of terms and operations.

Given an expression, 34 + 4/9 w

Put w = -1/2

34 + 4/9*(-1/2)

= 34 - 2/9

= 304/9 =  [tex]33\frac{7}{9}[/tex]

Hence, The value of expression 34 + 4/9 w at w = -1/2 is [tex]33\frac{7}{9}[/tex]

Answer:

What statements =?

Step-by-step explanation:

Your answer will be -1 2/10, or -1 1/5 if you're looking for a simplified answer. My method is called KCF, or Keep Change Flip. First, you don't have to do anything with the -4/5. Next, you would want to change the division to multiplication. It is possible to just divide across, but changing it to multiplication is way easier and will save time. After that, you would switch -2/3 to -3/2. FLIPPING THE SECOND FRACTION DOES NOT MEAN THE NEGATIVE TURNS INTO A POSITIVE. Your answer would be 12/10, but we aren't done just yet. 10 goes into 12 once, now we have 1 2/10 left over. If you simplify you will get 1 1/5. So there you have it! I answered you question as best as I could and I hope this was helpful.

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:

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:

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.
