Answers

Answer:

Step-by-step explanation:

18v^9 + 33v^8 +14v^7

Factor out v^7 from the expression

v^7 x (18v^2+33v+14)

write 33v as a sum

v^7 x (18v^2+21v+12v+14)                  *like this 21v+12v

Factor out 3v from the expression

v^7 x (3v x (6v+7)+12v+14)

Lines n and m (reading from top to bottom) are parallel to each other, and lines a and e are parallel to each other. The two pairs of lines intersect each other. Lines m and n start at top left and drop to the bottom right. Lines a and e rise from left to right. Only six of the sixteen angles created are labelled. Angle one is the top angle made by lines n and a. Angle two is the bottom angle. Angle three is the bottom angle made by lines m and a. Angle four is the top angle made by lines n and e. Angle five is the left angle. Angle six is the bottom angle made by lines m and e.

Angles that add up to 90 are Complementary angles.

Two angles that have a common vertex and a common side but do not overlap are Adjacent angles.

Angles that are opposite each other and have the same measurment are vertical angles.

Angles that add up to 180 are Supplementary angles.

Hope this helps!! :D

Supplementary angles - angles that add up to 180

Complementary angles- angles add up to 90

Adjacent -two angles that have a common vertex

What is the value of x?

Answers

Answer:

x = 30 degrees

Step-by-step explanation:

Okay so we start by noticing that the two pointed out vertices = 180 degrees. So we have the following equation.

(x + 12) + (3x + 48) = 180

If you combine them you get:

4x + 60 = 180

Subtract 60 from both sides..

4x = 120

Divide both sides by 4..

x = 30

Step-by-step explanation:

In a class in which the final course grade depends entirely on the average of four equally weighted 100-point tests, Joyce has scored 90, 93, and 85 on the first three. What range of scores on the fourth test will give Joyce a C for the semester (an average between 70 and 79, inclusive)? Assume that all test scores have a non-negative value.

Express your answer in interval notation.


HELP ASAP BRAINLEST AND THANKS

Answers

Answer:

[12,48]

Step-by-step explanation:

We will start by calculating the score she needs to get a 70 in the class

We will let x equal the fourth test

[tex]\frac{90+93+85+x}{4} =70[/tex]

This isn't hard to solve and we will do so by multiplying 4 by both sides and subtracting 268 (90+93+85)

This means that x= 12

We will then use the same formula but set it equal to 79

[tex]\frac{90+93+85+x}{4} =79[/tex]

We solve x in the exact same way and get x=48

our final answer is now [12,48]

Equation of the straight line in point-slope form

 y -(-7) = [tex]\frac{-3}{4}[/tex](x-8)

Equation of the straight line

3x +4y +4=0

Step-by-step explanation:

Explanation:-

Given that the point ( 8,-7) and  [tex]m = \frac{-3}{4}[/tex]

Equation of the straight line passing through the point (x₁, y₁) and having slope 'm'

          y - y₁ = m (x-x₁)

        y -(-7) = [tex]\frac{-3}{4}[/tex](x-8)

       4( y+7) = -3(x-8)
