Answer:
x = -1 or x = 7
Step-by-step explanation:
From my understanding, y will be zero and you have to find the value of x.
Step 1: Middle term break
y = x² + 6x - 7
x² + 6x - 7 = 0
x² - 7x + x - 7 = 0
Step 2: Solve
x(x-7) + 1(x-7) = 0
(x+1) (x-7) = 0
x = -1 or x = 7
Therefore, the value of x is either -1 or 7.

Answer:
not a function
Step-by-step explanation:
When a left-side point originates more than 1 arrow, the relation is not a function. There are two such points here, so this relation is not a function.
Two lines that are parallel have the same slope. Thus, the slope of the given line is 2 and the slope of the new line is also 2.
General slope-intercept equation of a str. line is y = mx + b.
Let m = 2: y = 2x + b
This new line passes thru (3,11). Thus, subst. 3 for x and 11 for y in
y = 2x + b, to find b:
11 = 2(3)+b
11 = 6 + b so b=5
Thus, the equation of the new line, parallel to the old, is y = 2x + 5.
