Which statement best describes the equation (x 5)2 4(x 5) 12 = 0?.
Answers
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.

Graph the line that has a slope of 10 and includes the point (0, 0).
Answers
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.

What is X equal to? It’s not 180 -.-
Answers
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

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:

Answer:
end behavior on left: function goes to + infinity
end behavior on the right: function goes to - infinity
Step-by-step explanation:
You look at the highest powered x term.
You look at the highest powered x-term which is - 3x^5. The polynomial will begin and end the same way a -x^5 curve begins and ends.
end behavior on the left side (as x approaches negative infinity), y values approach positive infinity. You can substitute negative values of x (-1, -5, -10, -100 . . .) in - 3x^5 and you will get increasing positive values for y as you use x values that approach negative infinity).
end behavior on the right side (as x approaches positive infinity), y values approach negative infinity. Substitute positive values for x (1, 10, 100, 1,000 . . .) in - 3x^5 and you will get decreasing negative values for y.

Answer:
b = 240Step-by-step Solution:
-17 + b/8 = 13=> b/8 = 13 + 17=> b/8 = 30=> 8 x b/8 = 30 x 8=> b = 240Hence, the value of b is 240.
