One is that they are all <em>real numbers</em>, or <em>rational numbers</em>.
Answer:
Solutions of the given equations is (-3,2).
Step-by-step explanation:
Here the equations given are y = -x²-6x-7------(1)
and y = 2---------(2)
Now we substitute the value of y from equation (2) into (1)
2 = -x²-6x-7
x²+6x+7 = -2
x²+6x+7+2 = 2-2
x²+6x+9 = 0
x²+3x+3x+9 = 0
x(x+3)+3(x+3) = 0
(x+3)(x+3) = 0
therefore value of x is x = -3
Therefore the solution is (-3,2).
Answer:
NM = 8
Step-by-step explanation:
Given rectangle JKLM
JN = x + 3 and JL = 3x + 1
JN = 1/2JL as diagonals bisect each other and N is the midpoint of JL.
Substitute and solve for x:
x + 3 = 1/2(3x + 1)
2x + 6 = 3x + 1
3x - 2x = 6 - 1
x = 5
Find JN
JN = 5 + 3 = 8
Looking at the options, we see that
NM = JN = 8
Correct option is A
