Answer:
The y intercept is (0,-1)
Step-by-step explanation:
To find the y intercept, let x = 0
y = -x^2 -6x-1
y = -0^2-6(0) -1
y = -1
The y intercept is (0,-1)

Step-by-step explanation:
The sum is formed by adding corresponding elements. For example, the lower right element (row 3, col 3) of the sum is 5+4 = 9
Answer:
B={1,2,3,4,6and12}
n (B) =6
Step-by-step explanation:
<h3>Greetings !</h3>
Factor, in mathematics, a number or algebraic expression that divides another number or expression evenly—i.e., with no remainder. For example, 3 and 6 are factors of 12 because 12 ÷ 3 = 4 exactly and 12 ÷ 6 = 2 exactly. The other factors of 12 are 1, 2, 4, and 12.
Hope it helps!
For Q3, you can subsitute x = 2 and y = 5 into the systems
-5(2) + 5 = -5
so it's a solution for the first system
-4(2)+2(5) = 2
it's also a solution for the second system
x=8+sqrt-8/12, x=8-sqrt-8/12
I think...
