Step-by-step explanation:
Remark
If x - 2 is a factor it means that the whole equation will return 0 when x = 2. That's because x - 2 will go to 0. It doesn't matter what the rest of the equation factors into. The x - 2 is enough to make it all go to 0.
Equation
y = x^4 - 3x^3 +2x - 8
Substitute and Solve
x = 2
y = 2^4 - 3*2^3 + 2(3) - 8
y = 16 - 24 + 6 - 8
y = - 8 - 2
y = - 10
Conclusion
x - 2 is not a factor of this equation.

Step-by-step explanation:
You are given two pairs of triangles. For the first pair of triangles, each side and angle of one triangle is congruent to the corresponding side and angle of the other. You show that rigid motions can transform one triangle so that it matches up with the other. For the second pair of triangles, you show that rigid motions can transform one triangle so that each angle or side of one triangle matches exactly with a corresponding angle or side of the other triangle. What have you proved?
Options:
a) If corresponding pairs of sides and corresponding pairs of angles of two triangles are congruent, then the triangles can be matched up exactly using rigid motions.
b) If two triangles can be matched up exactly using rigid motions, then the corresponding pairs of sides and corresponding pairs of angles of the triangles are congruent.
c) Two triangles can be matched up exactly using rigid motions if and only if corresponding pairs of sides and corresponding pairs of angles are congruent.
d) If corresponding pairs of sides and corresponding pairs of angles of two triangles are not congruent, then the triangles are not congruent.
Answer:
c) Two triangles can be matched up exactly using rigid motions if and only if corresponding pairs of sides and corresponding pairs of angles are congruent.
Step-by-step explanation:
For both pairs of triangles, what you proved is how to use rigid motions (i.e. rigid transformations) to make congruent shapes.
When rigid transformation is applied to a shape, the image (i.e. result) of the transformation produces an exact shape (i.e. equal corresponding angles and corresponding sides), meaning that the side lengths and the angles of the preimage (before transformation) and the image (after transformation) is unaltered.
Option (c) is true
Factor the trinomial.
X2 + 12x + 20
Answer:
(x + 10)(x + 2)
Step-by-step explanation:
x² + 12x +20
(x + 10)(x + 2)
Answer:
(x+2)(x+10)
Step-by-step explanation:
The given trinomial needs to be factorised. On the basis of degree of power of polynomial it can also be called a quadratic polynomial . General form is ax² + bx + c .
= x² + 12x + 20
By splitting middle term .= x² + 10x + 2x + 20
Taking x and 2 as common.= x ( x + 10 ) + 2( x + 10 )
Talking (x + 10) as Common .= ( x + 2)( x +10)
Hence the factorised form is (x+2)(x+10).2/5 of 16 simplify if you can thank you

a: 550-n×55
Step-by-step explanation:
because she withdraws every week 55 then the equation is that
Answer:
a. A = 550 - (n55)b. $165.00Explanation:
a. Amount of remaining dollars = $550 (the initial amount) - (numbers of weeks times $55 that she withdraws weekly)so the equation is: A = 550 - (n55)
b. using the equation in (a) we can determine the amount of money in Shirley's account after 7 weeks.A = 550 - (7×55)
A = 550 - 385
A = $165.00
What figure is a dilation of Figure A by a factor of 3?
Please help :)
Answer:
36×18×18×27
Step-by-step explanation:
Assuming the picture is Figure A you would multiply value from figure A by 3 to get corresponding value for dilated figure.
So if figure A is
12 × 6 × 6 × 9
the dilated figure would be
36 × 18 × 18 × 27

How many unit cubes are on each layer of this cube
There are 16 cubes in each layer.
What are cube?A cube is a three-dimensional solid object bounded by six square faces, facets or sides, with three meeting at each vertex. Viewed from a corner it is a hexagon and its net is usually depicted as a cross.
Given that, a cube,
Since, we know that, all sides of a cube are equal and the cross-section of the cube is a square,
Therefore, counting the cubes of the front face,
4 cubes vertical and 4 cubes horizontal,
Therefore, total cube in front face = 4×4 = 16
Therefore, cubes in each layer is 16.

A boat has a depreciation rate of 12% per year. If the original price of the boat was $15,000, what is the value of the boat 5 years later? Round your answer to the nearest penny (hundredths place value).
Answer: $7,915.98
Step-by-step explanation: This is an exponentially decaying problem, so that means we use the formula ab^x.
The a value is the original price or the starting point, which is 15,000. The b value is the ratio in which it decreases or increases. It is decreasing, so we subtract 12 from 100, which is 88. The ratio should be in decimal form, so it is 0.88. Finally, the x should be the exponent, the amount of times it is getting multiplied by the ratio. So the equation would be 15,000(0.88)^5.
Then, we solve.
0.88 * 0.88 * 0.88 * 0.88 * 0.88 = 0.5277319168
Then 0.5277319168 * 15,000 = 7,915.978752.
Of course, we round to the nearest hundredth, which is 7,915.98. Hope this helped.

C. A= 3n+18
D. A=3n+ 15 X
Answer:
D. A = 3n + 15
Step-by-step explanation:
3 should be beside the n variable because n represents each ride that was purchased.
As 15 represents the fee
The A variable represents the total amount spent
Therefore your answer is D.

JT bisects AJH and the measure of MJT is four times that of TJH. If the measures of MJT is 120 find the measure of MJA.
MJH = 120
Let TJH = x
You’re told MJT is 4 times TJH
So you have 4x + x = 120
Simplify: 5x = 120
Divide both sides by 5:
X = 24
TJH = x = 24 degrees.
JT is a bisector so both TJH and TJA are the same. So TJA is also 24 degrees
So MJA = 120 - 24 - 24 = 72
MJA = 72 degrees
