which equation has no real solutions

Answer:

-x aka -1

Step-by-step explanation:

x1   y1     x2   y2

9   -2       4   3  

m= y2 - y1/x2 - x1

m = 3 + 2/4 - 9

(The "-" sign turned positive because it is negative times negative)

5/-5

Simplify: 5/-5 = -1 = -x

The slope of this line is -x

Answer:

0< x < 2.5

Step-by-step explanation:

For this case we must find the interval for which the function is non-linear.

For this, we must define a linear function.

A linear function is a straight line that is generically:

y=mx+b

We observe that the function is non-linear from x = 0 to x = 2.5

Therefore, the interval for which the function is non-linear is given by:

[0,2.5]

Answer: It has 4 equal sides

Step-by-step explanation:  A rectangle with 4 equal sides is a square.

So, a rectangle is a rhombus when it is a square!

i cant see the image?

Step-by-step explanation:

if someone can please tell me what is shows

Answer:

Yes, this is A Linear Function!

Step-by-step explanation:

This is a linear function beacuse linear functions are straight lines on the graph as you may know. So when we graph these numbers it turns up as a straight increasing linear line.

Answer: x = -1

Step-by-step explanation:

The radius needs to be positive, so 2x + 3 > 0.  Solving for x, we get x > -3/2.  The smallest integer larger than -3/2 is -1, so x = –1.

Answer:

See attached graph

Step-by-step explanation:

The equation that has a slope of 10 and intersects (0,0) is:

y = 10x

The slope-intercept form of a straight line equation is y=mx+b, where m is the slope and b the y-intercept (the value of y when x = 0).  

In this case:

m = 10

b is 0 since the value of y when x = 0 is 0 (0,0).

See attached graph.

[tex]\huge\fbox{Hi\:there!}[/tex]

We are given the slope of the line and a point that it passes through, so we can use the Point-Slope formula:

[tex]\rm{y-y1=m(x-x1)[/tex]

Where

y1 is the y-coordinate of the point, m is the slope and x1 is the x-coordinate.

In this case:

y1=0

m=10

x1=0

Plug in the values:

[tex]\bf{y-0=10(x-0)[/tex]

Solve:

[tex]\bf{y-0=10x[/tex]

[tex]\bf{y=10x}[/tex]

Now, how to graph the line?

Let's look at its equation.

First of all, it has a y-intercept of 0, which means the line touches the y-axis at (0,0)

Now, what about the slope? The slope is 10.

Thus

We move "up 10, over 1, up 10, over 1" and so on, until we have a line.

Then all we have to do is take a ruler and connect the points.

Answer:

Option 1 is correct.

Step-by-step explanation:

Given the equation

we have to choose the best statement describes the above equation.

→ (1)

As, the highest degree of its monomials i.e individual terms with non-zero coefficients is 2.

⇒ Degree of above equation is 2.

hence, the given equation is quadratic equation.

The general form of quadratic equation is

In variable u: → (2)

Now, compare equation (1) with (2), we say that

The equation is quadratic in form because it can be rewritten as a quadratic equation with u substitution u = (x + 5).

Option 1 is correct.

Using the Pythagorean theorem:

47 ^2 = 11^2 + x^2

2209 = 121 + x^2

Subtract 131 from both sides

2088 = x^2

Take the square root of both sides

X = sqrt(2088)

Simplify

X = 6sqrt(58)

This question basically asks:

4 is 20% of what

So, just multiply everything by five so you turn that into

100% is 20

4 is indeed 20% of 20

Answer:

There is 20 total

Step-by-step explanation:

every 20% is 4, so you add 4 till you get 100%

Answer:

x = 163

Step-by-step explanation:

(x-5)+22= 180

x = 143

hope this helps!!!

Answer:

x = 163

Step-by-step explanation:

It is 180 and there is no doubt in it. a straight line always measures 180 and this is a straight line not even curved

to find the value of x

x - 5 + 22 = 180

x + 17 = 180

x = 180 - 17

x = 163

we can even cross check

163 - 5 + 22

158 + 22

= 180

if the line wasn't 180 I wouldn't able to cross- check

Buying as much auto insurance as you can afford is not the best idea.

Auto insurance is a type of insurance that provides you the following benefits:

Payments are agreed by customers, this means you can pay as much as you can, and by paying more you will have a wider coverage.

Despite this, investing as much money as is possible is not a good idea because incidents such as accidents are not so common and if you never experience one, the insurance is useless.

Answer:

Step-by-step explanation:

x = 65° ( vertically opposite angles )

y = 71° ( alternate angles )

The sum of the 3 angles in a triangle = 180° , then

x + y + z = 180° , that is

65° + 71° + z = 180°

136° + z = 180° ( subtract 136° from both sides )

z = 44°

So x = 65°, y = 71° , z = 44°

Answer:
