Answer:
x=13/4 or -1
Step-by-step explanation:
factorize the fraction
(4x^2+4x)(-13x-13)
4x(x+1) -13(x+1)
(4x-13)(x+1)
x=13/4 or x=1

Step-by-step explanation: Plot those two lines and they should appear the same as the graph, with the area to the left of (-1,-1) and between the lines greyed out.
If a²+b²=8ab, determine (a+b) in terms of a and b
[The question's not wholly right! Since, (a+b) has a and b in it, it already is in terms of a and b. Here, we'll be representing (a+b) in terms of ab]
Answer:
[tex]\mathsf{\sqrt{10ab} }[/tex]
Step-by-step explanation:
We have the rules of indices, one of which is:
[tex]\boxed{\large{\mathfrak{(a+b)^2=a^2+b^2+2ab}}}[/tex]
Indices are the powers, the numbers written as superscript in front of a variable or the numbers that come along with "^". It shows how many times a number is to be multiplied by itself.
In the question, we're provided with one equation, i. e.,
a² + b² = 8ab . . . . . . . . (¡)And, were asked to find out the value of (a+b) in terms of ab.
The above rule has variables that fit in the question efficiently!
So, instead of solving for (a+b), we'll be solving for (a+b)², then go for (a + b):
=> (a + b)² = (a² + b²) + 2ab
from eqn. (¡):
=> (a + b)² = 8ab + 2ab
=> (a + b)² = 10ab
taking under root on both the sides:
=> (a + b) = [tex]\mathsf{\sqrt{10ab} }[/tex]
That's the answer, [tex]\mathsf{\sqrt{10ab} }[/tex]!

A line is a one-dimensional shape that is straight. The equation of the given line in slope-intercept form can be written as y=(5/6)x -2.
What is the equation of a line?A line is a one-dimensional shape that is straight, has no thickness, and extends in both directions indefinitely. The equation of a line is given by,
y =mx + c
where,
x is the coordinate of the x-axis,
y is the coordinate of the y-axis,
m is the slope of the line, and
c is the y-intercept.
The given line goes through two points, (0, -2) and (6, 3). Therefore, the slope of the given line can be calculated as,
Slope, m = (-2 - 3)/(0 - 6) = -5 / -6 = 5/6
Further, it can be seen that the line intersects the y-axis of the graph at (0, -2), therefore, the y-intercept of the given line is -2.
Since the equation of a line in slope intercept form is written as y=mx+c. Therefore, substituting the slope and the y-intercept in the equation.
y=mx+c
y=(5/6)x -2
Thus, the equation of the given line in slope-intercept form can be written as y=(5/6)x -2.

it took jose two-thrids of an hour to complete his math homework on monday,three- fourths of an hour on tuewsday , and two- fifths of an hour on wednesday. how many hours did it take jose to complete his homework altogether
Given the line below.
Write the equation of the line, in point-slope form. Identify (x1, y1) as the point (-2, 2). Use the box provided to submit all of your calculations and final answers.
The slope of that line is -1, so m = -1.
The point you were told to use is (-2,2), so point-slope form starts as:
( y - 2 ) = -1 • ( x - (-2) )
But we'd clean up that x-(-2) to be x+2.
y - 2 = -1 ( x+2 )

6x - 2 = X + 13 what does X equal?
if you can pls show how you got it
Answer:
The answer is 3!!
Step-by-step explanation:
Step 1)
6x-2=x+13
6x − 2 + 2 = x + 13 +2
Step2)
6 = + 15
Step3)
6 − =+15−

What is the point halfway between (a, 2b) and (-a, 8b)?
The midpoint of the x values a and -a would be 0 because of a was a number the mid point between the negative and positive of the same number is 0
The midpoint of 2b and 8b is found by adding them together and dividing by 2:
2b + 8b = 10b / 2 = 5b
The midpoint is (0,5b)

list 21.3 ib 2064 g 16.7 kg 452 oz from least to greatst
Answer:
2064 g, 21.3 lb, 452 oz, 16.7 kg
Step-by-step explanation:
Let's change all units to grams to be able to compare the amounts.
21.3 lb * 454 g / lb = 9,670.2 g
2064 g = 2064 g
16.7 kg * 1000 g / kg = 16,700 g
452 oz * 1 lb / 16 oz * 454 g / lb = 12,825.5 g
From least to greatest:
2064 g, 21.3 lb, 452 oz, 16.7 kg

Answer:
PLEASE MARK BRAINLIEST
Step-by-step explanation:
y= mx + c
-y = 5- 3x
y= 3x - 5; m =3
since it is parallel
m1=m2
y- y1= m(x -x1)
y -7 =3(x -2)
y- 7=3x - 6

This unit is about polynomial and rational functions. What is a polynomial? What is a rational function? Are all polynomials rational functions, why or why not?
Answer:
What is a polynomial?
- In mathematics, a polynomial is an expression consisting of indeterminates and coefficients, that involves only the operations of addition, subtraction, multiplication, and non-negative integer exponentiation of variables
What is a rational function?
- In mathematics, a rational function is any function that can be defined by a rational fraction, which is an algebraic fraction such that both the numerator and the denominator are polynomials.
Are all polynomials rational functions?
.A function that cannot be written in the form of a polynomial, so no they are not all functions.

( −2 x^3) ^ 3 simplify
Answer:
[tex]-8x^9[/tex]
Step-by-step explanation:
We can split up the exponent into multiple products: [tex](-2x^3)^3=(-2)^3*(x^3)^3[/tex].
We know that [tex](-2)^3=(-2)*(-2)*(-2)=-1*-1*-1*2*2*2=-1*8=-8[/tex].
We also know that [tex](x^3)^3=x^{3*3}=x^9[/tex].
So, our answer is [tex]\boxed{-8x^9}[/tex] and we're done!
