Answer:
b = ±10
or
b = -10, 10
Step-by-step explanation:
Step 1: Write equation
b² = 100
Step 2: Solve for b
Square root both sides: b = ±10Step 3: Check
Plug in x to verify it's a solution.
(-10)² = 100
(10)² = 100
Answer:
b=-10 or b=10
Step-by-step explanation:
They would both work because negative times negative is also positive so it would also work.

The quadratic factors into (x + 4)(x + 2) When you remove the brackets, you get
x^2
2x
4x
8
They are all added and the 2x and 4x combine to get 6x.
Answer:
F (x) = x^2 + 6x+8 = F = x + 6 + [tex]\frac{8}{x}[/tex]
Step-by-step explanation:
Move all the expressions to the left side of the equation.
F(x)−x2−6x−8=0
Multiply F by x.
Fx−x2−6x−8=0
Move all terms not containing F to the right side of the equation.
Fx=x2+6x+8
Divide each term by x and simplify.
F = x + 6 + [tex]\frac{8}{x}[/tex]

The value of the product calculated by multiplication is 139594 .
A product is the result of multiplication or an expression that lists the factors to be multiplied.
According to the commutative law of multiplication, the outcome is unaffected by whether real or complex numbers are multiplied in a particular order.Usually, the order of the factors determines the outcome of a multiplication of matrices or the constituents of other associative algebras.For instance, multiplication in general and in matrices are non-commutative operations in other algebras.The product of multiplication of two complex numbers can also be a complex number.When two integers are multiplied we always get an integer .The given numbers are 338 and 413.
∴338 × 413 = 139594
Hence after multiplying the numbers we get 139594.

What is System of Equation?The system of equation is set of equations which have a common solution.
The figure shows the graph of two equations, these equations are a straight line function and the common solution is represented by a point in the image.
The solution of the system of equation can be obtained both by solving using substitution method and even by plotting the graph and finding the intersection point.
The system of equation is,
y = 2x - 7
y = -x -1
The value of y from equation 2 will be substituted in equation 1
-x -1 = 2x -7
3x = 6
x = 2
Substituting this value in equation 2
y = -2 -1
y = -3

The graph of the reciprocal parent function f(x)=1/x, is shifted 6 units down and 1 unit to the right to create the graph of g(x). What function is g(x)?
A. g(x)=1/x+6-1
B. g(x)=1/x-1-6
C. g(x)=1/x-6-1
D. g(x)=1/x+1-6
Answers
Transformations are used to move a function from one position to another. The new function g(x) is [tex]g(x) = \frac{1}{x-1} - 6[/tex]
Given that
[tex]f(x) = \frac 1x[/tex]
When shifted 6 units down. the rule of transformation is:
[tex](x,f(x)) \to (x,f(x) - 6)[/tex]
So, we have:
[tex]f'(x) = f(x) - 6[/tex]
[tex]f'(x) = \frac 1x - 6[/tex]
When shifted 1 unit left. the rule of transformation is:
[tex](x,g(x)) \to (x -1,f'(x))[/tex]
So, we have:
[tex]g(x) = f'(x - 1)[/tex]
[tex]g(x) = \frac{1}{x-1} - 6[/tex]
Hence, the new function g(x) is [tex]g(x) = \frac{1}{x-1} - 6[/tex]

Step-by-step explanation:
To find the x value, you need to use reverse PEMDAS (or GEMDAS as I've seen some people call it)
First, you subtract 4 from both sides of the equation. This should give you:
1/2x=11
Then, you divide 1/2 on each side. Although it's easier to multiply 2 on each side instead. This will give you.

What is the image of (3, 6) when it is translated along the horizontal vector -2,0?
Answers
Answer: (1,6)
The vector <-2,0> means we shift the input point two units to the left.
This is the same as writing the rule [tex](x,y) \to (x-2,y)[/tex]
Subtract 2 from the x coordinate. The y coordinate stays the same.
After the translation the point becomes P'(1, 6).
What is the difference between upward, downward, leftwards and rightwards translation?Upward translation : [k] units = When the upward translation take's place then, each point will have its y - coordinate shifted upwards by +k units.Downward translation : [k] units = When the downward translation will take place then, each point will have its y - coordinate shifted downwards by -k units.Leftward Translation : [k] units = When the leftward translation will take place then, each point will have its x - coordinate shifted by -k units to the left.Rightward Translation : [k] units = When the rightward translation will take place then, each point will have its x - coordinate shifted by +k units to the rightGiven is a coordinate point (3, 6).
The horizontal vector is given by -
A = - 2i + 0j + 0k
A = - 2j
When the point is translated along the vector, then, we can write -
P(3, 6) → P'(3 - 2, 6) → P'(1, 6)
P'(1, 6)
Therefore, after the translation the point becomes P'(1, 6).
