Simplify the expression:
–7c2–c2+–5c2–2c2+8c2–9c2

Answers

Answer 1

Answer:

the answer is why is math so hard

Step-by-step explanation:

Duh

Answer 2
i would start by grouping them into sections because they’re all like terms.
(-7c2-c2) = -8c2
(-5c2-2c2)= -7c2
(8c2-9c2) =-c2
then add them all together.
-8c2-7c2-c2
since they’re all negative you can add them together but don’t forget the negative.
8+7=15
15+1 = 16
add the negative back in to get -16c2

Answer:

b = 17.55

Step-by-step explanation:

a^2 + b^2 = c^2

4^2 + b^2 = 18^2

16 + b^2 = 324

-16              -16

b^2 = 308

square root them

b = 17.55

let me know if it is correct!

Step-by-step explanation:

4^2 + h^2 = 18^2

16 +h^2 = 324

h^2 = 308

h = √308

h = 17.5499 ft

The lines 2x - y = 8 and 4x - 2y = 16 intersect at _______.

Answers

there both the same equation so it’s c
answer-C.

The solution is Option C.

The system of equations are same and they have infinite number of points

What is an Equation of a line?

The equation of a line is expressed as y = mx + b where m is the slope and b is the y-intercept

And y - y₁ = m ( x - x₁ )

y = y-coordinate of second point

y₁ = y-coordinate of point one

m = slope

x = x-coordinate of second point

x₁ = x-coordinate of point one

The slope m = ( y₂ - y₁ ) / ( x₂ - x₁ )

Given data ,

Let the equation of line be represented as A

Now , the value of A is

Let the first equation be P

2x - y = 8   be equation (1)

Let the second equation be Q

4x - 2y = 16  be equation (2)

Now , the slope of the line is m = ( y₂ - y₁ ) / ( x₂ - x₁ ) = 2

Substituting the values in the equation , we get

Divide equation (2) by 2 , we get

2x - y = 8   be equation (1)

Therefore , the value of equation (1) = equation (2)

Hence , there are infinite number of solutions to the equations

A box contains 6 red marbles, 4 green marbles, 3 blue marbles, and 2 yellow marbles. If Greg chooses one marble at random 300 times, how many times would he expect the marble to be blue?

Answers

Answer:

[tex]60[/tex] times

Step-by-step explanation:

There are [tex]6+4+3+2=15[/tex] marbles in total. Out of those, [tex]3[/tex] are blue, so the probability of pulling a blue marble is [tex]\frac{3}{15}=\frac{1}{5}[/tex]. However, this is only the probability of pulling a blue marble when [tex]1[/tex] marble is pulled at random. Therefore, we can expect a blue marble to be pulled [tex]\frac{1}{5}*300=60[/tex] times if [tex]1[/tex] marble is pulled [tex]300[/tex] times at random. Hope this helps!

6) Write a system of linear inequalities that is given by the following graph.

Answers

Answer:

The system of inequalities are x - y < 1 and y < - 2 The horizontal line shown in the graph has equation y = - 2 {As it is parallel to x-axis} Now, this line is dotted and the lower portion of the graph is shaded. So, the inequality will be y < - 2 ......... (1) Again, another line is there in the graph which passes through the points (1,0) and (0,-1)So, its equation will be

⇒ y + 1 = x ⇒ x - y = 1 Now, the origin (0,0) is within shaded zone of the inequality and putting x = 0 and y = 0, we get 0 - 0 < 1 So, the equation of the inequality is x - y < 1 {As the line is dotted} Therefore, the system of inequalities are x - y < 1 and y < - 2 (Answer)
