solve the following equation ​

Answers

Answer:

x=1 x=-11

Step-by-step explanation:

first you need to find what two numbers add together to make 10x and multiply together to make 25-

this would be 5

so we can rewrite it as (x+5)(x+5) = 36

which is the same thing as (x+5)^2 =36

then taking the root of both sides we get (x+5)= plus or minus 6

so x=-11 or x equals 1

Write an inequality that represents the graph.

(it’s #4)

Answers

Answer:

x > 2

Step-by-step explanation:

Let x = unknown number

The dot is at 2.

The dot is also an open circle meaning that 2 is not included. When the dot is an open circle we use < or > rather than ≤ and ≥

The line is going to the right towards the larger numbers.

This means that the solution to the inequality is greater than 2.

This can be represented as x > 2

Answer: x >2

Step-by-step explanation: It has an open circle and is pointing in the greater than direction. Therefore, it is written as x >2 which reads x is greater than 2. Of course, you could use any variable (letter) that you wish to choose.

Hope this helps.

Complete the missing value in the solution to the equation

Answers

Answer:

(3,3)

Step-by-step explanation:

To find the y - value that corresponds to x=3 , substitute the x - value in the equation.

y=4x-9

y=4*3-9

y=12-9

y=3

Therefore, (3/3) is the solution to the equation.

which of the following rational functions is graphed below? A f(x) = x/(x+5)(x-2) B f(x)= x-2/x(x+5) C f(x)= (x+5)(x-2)/x D f(x)= 1/(x+5)(x-2)

Answers

Answer:

  A  f(x) = x/((x+5)(x-2))

Step-by-step explanation:

The vertical asymptotes at +2 and -5 indicate that (x -(+2)) and (x -(-5)) are factors of the denominator.

The zero at x=0 indicates (x -0) is a factor of the numerator.

The simplest function that will give a graph like this is ...

  f(x) = x/((x +5)(x -2))

Regan cycles 78 miles in 6 hours.
His average speed for the first 30 miles is 15 mph.

Work out Regan's average speed for the last 48 miles.

Answers

Answer:

12 mph

Step-by-step explanation:

First 30 miles while cycling at 15 mph. This means he spent 2 hours here.

Thus the 4 hours on the last 48 miles.

Average speed  =  distance / time

Average speed = 48 miles / 4 hours

Average speed = 12 mph

Therefore Regan's average speed is 12 mph for the last 48 miles.

Which statements are true about the ordered pair (7, 19) and the system of equations?

{2x−y=−5x+3y=22


Select each correct answer.


The ordered pair (7, 19) is a solution to the first equation because it makes the first equation true.

The ordered pair (7, 19) is a solution to the second equation because it makes the second equation true.

The ordered pair (7, 19) is not a solution to the system because it makes at least one of the equations false.

The ordered pair (7, 19) is a solution to the system because it makes both equations true.

Answers

Answer: The ordered pair (7, 19) is not a solution to the system because it makes at least one of the equations false.

Step-by-step explanation:

In the ordered pair (7,19), 7 is the x and 19 is the y. Plug those in and multiply.

2(7)-19=-5

-5=-5

7+3(19)=22

64 doesn't =22

SO, one part of the equation is wrong making the ordered pair wrong.

What are values of a and b so the system of equations shown has no solutions?

y=7x+b
y=ax+4

Answers

Answer: a is 7 b is 4

Step-by-step explanation: to get an equation with no solution the equation has to be the same so if a is 7 and b is 4 this will show no solution

A=7 and b= anything other than 4. The reason for this is because the lines must never touch (equal slope with different y intercept provides a parallel line that does not meet the original function). A solution is a point in which the two functions intersect. The other answer under this post is incorrect, as they have actually given you INFINITE solutions rather than none.
