Answer:
(x + 1)(x - 7) is the odd one.
Step-by-step explanation:
1) sum= 8
Product = 7
Factors = 1 , 7 {1*7 = 7 & 1+7 = 8}
x² + 8x + 7 = x² + x + 7x + 7
= x(x + 1) + 7(x + 1)
=(x +1 )(x + 7)
2) x² - 8x + 7 = x² -x -7x + (-1)*(-7)
= x(x - 1) - 7(x - 1)
=(x - 1)( x - 7)
3)Sum = 6
Product = -7
Factors = (-1) , 7 { -1 + 7 = 6 & (-1)*7 = -7}
x² + 6x - 7 = x² - x + 7x - 7
= x(x - 1) + 7(x - 1)
= (x - 1)(x + 7)
Answer:
(x+1)(x-7) is the odd one out

Answer:
The answer is -21.1 degrees
Step-by-step explanation:
You get this by simply subtracting 17.5 from a negative 3.6. This will look like -3.6-17.5= x. Doing that gets you a negative 21.1. I hope this helps!

the first one is equivalent and the second one is not equivalent
Step-by-step explanation:
In the first one do the distributive property first by distributing the the -2.
[tex]3x - 4.6x - 5 = 1.6x - 5[/tex]
collect like terms on the left side
[tex] - 1.6x - 5 = - 1.6x - 5[/tex]
they are equivalent.
The second equation do the distributive property first by multiplying by -3.
[tex]5 + 4.8x + 6.3 = 4.8x - 1.3[/tex]
collect like terms on the left.
[tex]4.8x + 11.3 = 4.8x - 1.3[/tex]

Process
1.- Find the cos a
Opposite side = 5
Hypotenuse = 13
Adjacent side = ?
Adjacent side² = 13² - 5²
= 169 - 25
= 144
Adjacent side = 12
cos a = 12/13
2.- Find the sin b
sin b = 5/13
3.- Use the formula below to find sin(a + b)
sin (a + b) = sina cosb + sin b cos a
- Substitution
sin (a + b) = (5/13)((-12/13) + (5/13)/12/13)
- Simplification
sin (a + b) = -60/169 + 60/13
- Result
sin(a + b) = 0

Write an equation of the line that passes through the point (6,2) and is perpendicular to the line y=3x+3
Answers
Answer:
y = - [tex]\frac{1}{3}[/tex]x + 4
Step-by-step explanation:
To find the slope of a perpendicular line, find the negative reciprocal of the slope.
The slope is 3 so the slope of the perpendicular line would be - [tex]\frac{1}{3}[/tex]
________________
Then use point slope form to find the equation of the perpendicular line:
y - [tex]y_{1}[/tex] = m (x - [tex]x_{1}[/tex] )
point = (6, 2)
slope = - [tex]\frac{1}{3}[/tex]
y - 2 = - [tex]\frac{1}{3}[/tex] (x - 6)
________________
If you want it in slope intercept form, you can just rearrange the equation:
y = 2 - [tex]\frac{1}{3}[/tex]x +2
y = - [tex]\frac{1}{3}[/tex]x + 4

Give an equation for the result of shifting the graph of up by 4 units, and left by 2 units.
An equation is written as two expressions connected by the equal sign
Enter an equation for the shifted graph:
Answers
We define transformations as operators that act on functions by modifying them in some given way. One type of transformation is a translation, which will move the whole graph of the function in some give direction.
For a general function f(x), we will find that the equation for the result of shifting the graph up by 4 units and left by 2 units is:
g(x) = f(x + 2) + 4
----------------------------------
Let's see how to solve this.
We need to start by defining the two most common translations (also known as shifts).
Horizontal translation:
For a given function f(x), an horizontal translation of N units is written as:
g(x) = f(x + N)
where if N is positive, the translation is to the left.
If N is negative, the translation is to the right.
Vertical translation:
For a given function f(x), a vertical translation of N units is written as:
g(x) = f(x) + N
Where if N is positive, the translation is upwards.
If N is negative, the translation is downwards.
Here for an unknown function f(x), we want to write the equation that gives a shift up of 4 units and left by 2 units.
The shift up of 4 units is written as:
g(x) = f(x) + 4
The shift of 2 units to the left is written as:
g(x) = f(x + 2)
These two together give:
g(x) = f(x + 2) + 4.
This is the equation we wanted to get.
