Answer:
measure of both angle is 66
Step-by-step explanation:
vertical angles are equal so,
6x+15=4x+32
6x-4x=32-15
2x= 17
X=8.5
now,
4X+32
= 4×8.5 +32
= 66
Answer:
60
Step-by-step explanation:
since we are taking 5 trys to each room and there are 12 you would multiply 5 by 12 making it 16
Answer:
No
Step-by-step explanation:
Let's check the first statement with an example. 2 and 3 are positive numbers and their sum (5) is also positive so his first statement is true.
To check the second statement let's look at the negative numbers -1 and -8 for example. Their sum (-9) is also negative so his second statement is true.
To check the third statement let's look at the numbers 9 and -5. One is positive and one is negative, but their sum (4) is positive, so his third statement is false. However if we look at the numbers 4 and -7, their sum is negative so the third statement is partially false.
Answer:
Option B
Step-by-step explanation:
we know that
The critical point of a function are the points on the graph of a function where the derivative is zero or the derivative does not exist.
we have
step 1
Take the derivative of the function
step 2
Set that derivative equal to 0 and solve for x. Each x value you find is known as a critical number
<em>Alternative Method</em>
The critical point of the quadratic equation is the vertex, because the function changes from decreasing to increasing at that point (In this problem the vertex is a minimum)
we have
Convert into vertex form
the vertex is the point (-2,-15)
therefore
The x-coordinate of the critical point is x=-2
