Answer:
ON = KJ
Step-by-step explanation:
JKL = NOP
We know the angles match
<J = <N
<K = <O
< L = <P
And we know
JK = NO
KL = OP
JL = NP
We are looking for ON = KJ
1. x is less then or equal to -1 or x is greater then or equal to 5.
2. x is greater then -4 and x is less than or equal to -1
The reason it is equal to or not is because above the original number there is a dot. If it is not filled in, it is considered open. This would leave it as greater than or less than. If it were filled in, it would be considered closed. Leaving it as greater than or equal to or less than or equal to.
Uh for the second question, his height in decimal form would be 4.75, kind sir.
Hope this helped,
Yes, u are correct, hope this helped
Answer:
k can either be
12
or
−
12
.
Step-by-step explanation:
Consider the equation
0=x2+4x+4
. We can solve this by factoring as a perfect square trinomial, so
0=(x+2)2→x=−2 and−2
. Hence, there will be two identical solutions.
The discriminant of the quadratic equation (b2−4ac) can be used to determine the number and the type of solutions. Since a quadratic equations roots are in fact its x intercepts, and a perfect square trinomial will have
2 equal, or 1
distinct solution, the vertex lies on the x axis. We can set the discriminant to 0 and solve:
k2−(4×1×36)=0
k2−144=0
(k+12)(k−12)=0
k=±12
