The part of the quadratic formula that dictates whether the function is factorable or not is B. b^2 - 4ac. This determines the number of real, imaginary, negative and positive roots.
In the equation <span>2x^2 + 7x + 3,
we use the quadratic formula
x = -b +- sqrt (b2 -4ac) /2a = -7 +- </span><span>sqrt (49 -24) /4
the answers are x1 =-0.5 and x2 = -3.</span>
Answer: $3.42
Step-by-step explanation:
Interest= Principal x Rate x Time
From the question, Principal =$2,150
Rate= 22.9% annually means per year, to calculate the monthly rate, we divide by 12
=22.9%/12 = 1.908% per month
Time = one month, meaning one month out of 12months = 1/12
I is therefore: 2150 x 1.908% x 1/12
= 2150 × 0.01908 x 0.0833
=$3.42
I hope this is clear, please mark as brainliest answer.
1- Line:
A line is a one dimensional figure that is formed by joining an infinite set of points.
It has no start and no end.
Answer:
Line ..............> A) infinite number of points extending in opposite directions that has only one dimension
2- Line segment:
It is the same as the line. The only difference is that a line segment has a fixed start point and a fixed end point. It is considered to be a portion of a line
Answer:
Line segment .........> D) a part of a line that has two endpoints
3- Ray:
A ray is also a one dimensional shape. A ray usually has a start point but no end point.
Answer:
Ray .........> B) part of a line that has one endpoint and continues in one direction infinitely
4- Point:
A point is a dimensionless geometric shape. It is only used to state a certain location.
Answer:
Point .........> C) a location, has no dimension
5- Vertex:
A vertex is a term that is used to refer to the point where the two rays forming an angle meet.
Answer:
Vertex ........> E) the common endpoint of two segments or rays that form the corner of an angle
Hope this helps :)
The answer to this question is
x = -15 + y
0.4 because if it’s five or more, add one more. If it’s four or less, let it rest.
