Answer: x = 5
Step-by-step explanation: You Have To Move The Number 6 to the right beause it has no variable then solve the equation.
Answer:
0.699
Step-by-step explanation:
cos(5*20*34)
cos(3400)
0.699
To solve this problem, we must substitute in 1 for the variable x in the equation. This is because the function as written is f(x), meaning that the function is evaluated as x currently, but we want to evaluate it at 1. To do this, all we have to do is replace each variable x with a 1 and simplify.
f(x) = x^2 + 2x + 3
f(1) = (1)^2 + 2(1) + 3
To simplify, we first to compute the exponents. This is because of the order of operations, which says that we should solve parentheses first, exponents next, then multiplication/division, then addition/subtraction last.
f(1) = 1 + 2(1) + 3
Next, as outlined above, we should perform the multiplication.
f(1) = 1 + 2 + 3
Finally, we can finish solving by adding together the remaining terms.
f(1) = 6
Therefore, your answer is 6.
Hope this helps!
Answer:
(2, 22 )
Step-by-step explanation:
Given the 2 equations
y = 7x + 8 → (1)
y = x + 20 → (2)
Substitute y = 7x + 8 into (2)
7x + 8 = x + 20 ( subtract x from both sides )
6x + 8 = 20 ( subtract 8 from both sides )
6x = 12 ( divide both sides by 6 )
x = 2
Substitute x = 2 in (2) for corresponding value of y
y = x + 20 = 2 + 20 = 22
Solution is (2, 22 )
