Answer: x = -1
Step-by-step explanation: To solve this equation, we start by distributing the 4 through the parentheses on the left side.
So we have 4 times 5x which is 20x and 4 times 30 which is 120.
So our equation now reads 20x + 120 = 100.
Solving from here, we subtract 120 from both sides of the equation and we have 20x = -20 and dividing both sides by 20, we find that <em>x = -1</em>.
Answer:
x = 2
Step-by-step explanation:
At the point of intersection f(x) = g(x), thus
10x - 6 = x + 12 ( subtract x from both sides )
9x - 6 = 12 ( add 6 to both sides )
9x = 18 ( divide both sides by 9 )\
x = 2 ← at point of intersection

Answer:
x^2 -14x +49
( x-7)^2
Step-by-step explanation:
x^2 -14x
We are completing the square
Take the coefficient of x
-14
Divide by 2
-14/2 = -7
Square it
(-7)^2 = 49
Add it
x^2 -14x +49
Take the -7
( x-7)^2
Answer: Function, not a function, Function, not a function
Step-by-step explanation:
For it to be a function, each value of x has to map onto one value of y.
- This is a function.
- Not a function since x=-1 has more than one y value.
- This is a function
- Not a function since x=-6 has more than one y value.
