Subtract 2x 2 - 6x - 4
from 4x 2 - 4x + 3.
Answers
Subtracting the polynomials, 2x² - 6x - 4 from 4x² - 4x + 3 will give 2x² + 2x + 7
How to subtract polynomials?
Polynomials can have constants, variables and exponents, but never division by a variable.
Let's do the arithmetic of the polynomial.
4x² - 4x + 3 - (2x² - 6x - 4)
Therefore, let's open the bracket with the operator
4x² - 4x + 3 - 2x² + 6x + 4
let's combine the like terms
4x² - 2x²- 4x + 6x + 3 + 4
Therefore,
2x² + 2x + 7

Based on the graph, what is the initial value of the graph and what does it represent?
0.23 foot per minute; it represents the speed of the mouse
9 feet; it represents the original distance of the mouse from its hole
0.23 foot; it represents the original distance of the mouse from its hole
9 feet per minute; it represents the speed of the mouse
Answers
Answer:
The initial value is (0,9).
Hence option B is correct.
Step-by-step explanation:
Based on the graph, the initial value of the graph is (0,9)
where x=0 and y=9
where for the coordinate (x,y) ; x represents the time in minutes and y denotes the distance of the mouse from the hole in feet.
That means initially(i.e. at time t=0) the mouse is 9 feet away from the hole.
Hence the answer is 9 feet; it represents the original distance of the mouse from its hole.
Hence option B is correct.

100 + x + x = 180
(we know it's not the 100° angle that has a congruent match because that would cause the total angle measure to go above 180°)
100 + 2x = 180
Subtract 100 from each side.
2x = 80
Divide by 2.
x = 40°
Both of the other angles would be 40°.
There's no "most likely" about it.
==> Every isosceles triangle has two equal angles.
==> In this one, the 100-degrees angle is either one of the two equal angles,
or else it isn't.
==> If the 100 is one of the two equal angles, then the other one is also 100,
and the sum of the angles in this triangle ... even without the third one ...
is already more than 180 degrees.
==> So the 100 CAN'T be one of the equal angles. It must be the third angle.
-- Now there are 80 degrees left over to split between the other two angles,
which ARE equal.
-- The other two angles, which are not 100 degrees, MUST be 40 degrees each.
Not probably, not maybe, not could-be, and not "most likely". They must be.

The distance between points (10, 7) and (2, 7) on a coordinate plane is 8 units.
The given coordinate points are (10, 7) and (2, 7).
What is distance formula?
The distance formula which is used to find the distance between two points in a two-dimensional plane is also known as the Euclidean distance formula. On 2D plane the distance between two points (x1, y1) and (x2, y2) is Distance = √[(x2-x1)²+(y2-y1)²].
Substitute (x1, y1)=(10, 7) and (x2, y2)=(2, 7) in the distance formula, we get
Distance = √[(2-10)²+(7-7)²]
= √64
= 8 units
Therefore, the distance between points (10, 7) and (2, 7) on a coordinate plane is 8 units.

B) SAS
D) ASA
E) AAS
F) HL
G)not congruent
Answers
Answer: E) AAS
Explanation:
AAS stands for Angle Angle Side. The order is important because the side is not between the angles.
The diagram shows that
- angle A = angle D
- angle C = angle F
- side AB = side DE
Items 1 and 2 above correspond to the "A"s of "AAS", while item 3 refers to the "S".
Once again, the order of AAS is important. We don't go for ASA because side AB is not between angles A and C. Same for DE not between angles D and E.
