Answer:
True
Step-by-step explanation:
So, again, from the most right column, we can add 5, -6, and -2 to get -3. We now know that every row or column must be equal to -3.
The question is asking if the number square below is -3. We found out from above that is -3 so it's true.

move vertices A B and C to modify the original parallelogram. As you change the parallelogram, notice what happens to the diagonals. How does moving the vertices affect the relationship between the diagonals that you noted in question 2?
Moving the vertices does not affect the relationship between the diagonals. They bisect each other in all cases.
Answer:
Despite changing the vertices, the opposite sides and opposite interior angles of the parallelogram remain equal.

Solve for the value of w. (8w-7) (7w+8)°
Answer:
W1=0.875.
W2= -1.14
Step-by-step explanation:
(8w-7)(7w+8)
8w(7w+8)-7(7w+8)
56w^2+64w-49w-56
56w^2+15w-56
Solve it by quadratic equation
a=-b+-√(b^2-4ac)/2a
Substitute the values
And you will get 2 answers
a=-56
b=15

Answer:
[tex]\huge{\boxed{\sf{ -20i^{2} + 48i - 16}}}[/tex]
Step-by-step explanation:
( 8 - 4i ) ( 5i - 2 )
Use the distributive property to multiply each term of the first binomial by each term of the second binomial.
⇒[tex]8 ( 5i - 2 ) - 4i ( 5i - 2 )[/tex]
⇒[tex]40i - 16 - 20i^{2} + 8i[/tex]
Combine like terms.
Like terms are those which have the same base.
⇒[tex]- 20i^{2} +40i+ 8i - 16[/tex]
⇒[tex]-20i^{2} + 48i - 16[/tex]
Hope I helped!

A construction worker lowers a 100-foot rope from the top of a building. Another worker attaches the bottom of the rope to the ground, 23 feet from the base of the building. What is the height of the building rounded to the nearest foot?
Answer:
97 ft
Step-by-step explanation:
The Pythagorean theorem is useful for working problems like this. It tells you the relationship between side lengths and the hypotenuse of a right triangle.
Here, the building is presumed to be perpendicular to the ground, so the 100' rope is the hypotenuse of a triangle with legs equal to 23' and the height of the building (b).
23² +b² = 100²
b = √(10000 -529) ≈ 97.32
The height of the building is about 97 feet.
A rental car agency charges a flat fee of $111.00 plus $29.00 per day to rent a certain car. Another agency charges a fee of
$86.00 plus $34.00 per day to rent the same car.
Find the number of days for which the costs are the same. Round your answer to the nearest whole number of days.
Answer:4
Step-by-step explanation:
110 + $29= 139
86 + 34= 120
bascially 34 - 29 = 5
how many times will we have to plus 5 on the bottom numbers to make 139
Its 4

Assume that y varies inversely with x. If y=1/3 when x=1/2, find y when x=1/4.
Answer:
y = [tex]\frac{2}{3}[/tex]
Step-by-step explanation:
Given that y varies inversely with x then the equation relating them is
y = [tex]\frac{k}{x}[/tex] ← k is the constant of variation
To find k use the condition y = [tex]\frac{1}{3}[/tex] when x = [tex]\frac{1}{2}[/tex] , thus
[tex]\frac{1}{3}[/tex] = [tex]\frac{k}{\frac{1}{2} }[/tex] = 2k ( divide both sides by 2 )
k = [tex]\frac{1}{6}[/tex]
y = [tex]\frac{1}{6x}[/tex] ← equation of variation
When x = [tex]\frac{1}{4}[/tex] , then
y = [tex]\frac{1}{6(\frac{1}{4}) }[/tex] = [tex]\frac{1}{\frac{3}{2} }[/tex] = [tex]\frac{2}{3}[/tex]

Use the divisibility rules to determine which of the following numbers 315 is divisible by.(Check all that apply.)
-2
-3
-5
-7
-11
Answer: 3, 5, 7
Step-by-step explanation:
There is a "trick" to determine divisibility by 3: if the sum of the digits is divisible by 3, the number is divisible by 3.
3 + 1 + 5 = 9 which is a multiple of 3, so 315 is divisible by 3.
It works for 9 also. since the sum of the digits is 9, 315 is divisible by 9.
Divisibility by 5: any number that has the units digit 5 or 0 is divisible by 5.
For 7, I just tried it 315÷7= 45
Only even numbers are divisible by 2.
If a 3-digit number is divisible by 11, the middle digit will be the sum of the first and last digits. (That is not the case for 315) But 385 is divisible by 11, also 495, 253, and many others you can try for fun.
What is the value of k
Answer:
k = 5
Step-by-step explanation:
3x + k
im going to replace the x with the numbers that go there
3 x 1 + k = 8
3 x 1 = 3
8 - 3 = 5
k = 5
3 x 3 + k = 14
3 x 3 = 9
14 - 9 = 5
k = 5
3 x 5 + k = 20
3 x 5 = 15
20 - 15 = 5
k = 5

A. 0
B. 1
C. Infinitely many
D.2
Answer:
A. 0
General Formulas and Concepts:
Perpendicular Lines always have 1 solution.
Parallel Lines always have no solution.
Same Lines always have infinite amount of solutions.
Step-by-step explanation:
We see from the graph given that the 2 lines are parallel. Since they are parallel, they will never intersect.
Therefore, we would have no solution, or 0 solutions, as our answer.

can someone help me out on this please?
Answer:
Alexis: 2.5x
Gary: x
James: x + 18
Total: (2.5x) + (x) + (x + 18)
= 4.5x + 18
Bonus:
4.5x + 18 = 1206
4.5x = 1188
x = 264
Alexis: 2.5(264) = 660
Gary: 264
James: 264 + 18 = 282
Santa Claus has been experiencing some recent back pain and is unable to carry large bags of toys over his shoulders. As a result he uses redex to deliver many of his gifts this year. Fedex charges a flat rate of $2.50 plus $0.85 per pound. If the cost of sending gifts to the Jones is $28.85, how much did their gifts weigh?
Answer: 31 pounds
Step-by-step explanation:
From the question, we are informed that Fedex charges a flat rate of $2.50 plus $0.85 per pound and that the total cost of sending gifts to the Jones is $28.85. This can be mathematically expressed as:
2.50 + 0.85p = 28.85
where p = weight of the gift
So we have to solve the equation
2.50 + 0.85p = 28.85
0.85p = 28.85 - 2.50
0.85p = 26.35
p = 26.35/0.85
p = 31
Therefore the weight of the gift is 31 pounds

solve for x in geometry
Answer:
x = 3
Step-by-step explanation:
The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.
28x - 2 is an exterior angle of the triangle, thus
28x - 2 = 15x - 3 + 40 = 15x + 37 ( subtract 15x from both sides )
13x - 2 = 37 ( add 2 to both sides )
13x = 39 ( divide both sides by 13 )
x = 3
