Using this graph, determine and state all values of x for which f(x) = g(x).
Answer:
3/2
Step-by-step explanation:
TO figure out the slope on a graph, we have to use the Rise/Run method to get to the other point.
Answer:
Step-by-step explanation:
The problem tell us that is the inverse of , where:
So, we need to find the inverse function of in order to find
Let's find the inverse function using the following steps:
1. Replace with :
2. Solve the equation for :
3. Replace every with a and replace every with a :
4. Finally, replace with
Therefore:
Answer:
x = - 7, x = - 1
Step-by-step explanation:
Given
x² + 8x + 7 = 0
Consider the factors of the constant term (+ 7) which sum to give the coefficient of the x- term (+ 8)
The factors are + 7 and + 1 , since
7 × 1 = 7 and 7 + 1 = 8 , then
(x + 7)(x + 1) = 0 ← in factored form
Equate each factor to zero and solve for x
x + 7 = 0 ⇒ x = - 7
x + 1 = 0 ⇒ x = - 1
Answer:
Step-by-step explanation:
where a 0 so a = 1 b = 8 c = 7
Quadratic Formula:
Evaluate the exponent and multiply 4ac
Subtract b^2 - 4ac and multiply 2a
Solve for the sqrt root of 35
x = - 8 ± 6/2 =
x = - 8 + 6/2 = -1
x = - 8 - 6/2 = -7
2x + 2y = 2
(3, 4)
(-4, 5)
(2, -1)
Solution :
Given equations,
Applying Substitution method to solve the equation.
Solve the first equation for x,
Substitute the value of x in second equation,
To calculate the value of x substitute the value of y in first equation
Hence, the solution of the equations is (2,-1).
