Which property is illustrated by the statement 6 X 4=4 X 6?
Answer:
Commutative property
Step-by-step explanation:
Julio tested the point (4, –2) to see whether it is a solution to this system of equations.
–3x – 2y = –8,
y = 2x – 5
His work is shown below.
Negative 3 (4) minus 2 (negative 2) = negative 8. Negative 12 + 4 = negative 8. Negative 8 = negative 8. Therefore, (4, negative 2) is a solution to the system.
Did Julio verify the solution?
No. He substituted 4 and –2 for the wrong variables.
No. He did not check the point in the second equation.
No. He simplified the equation incorrectly.
Yes. He verified that (4, –2) is a solution to the system of equations.
Answer:
the answer is B on edge

For the right triangle find the missing length. Round your answer
to the nearest tenth.
Answer:
w = 5
Step-by-step explanation:
In the given right triangle, by trigonometric ratio, we have:
[tex] \tan \: 60 \degree = \frac{5 \sqrt{3} }{w} \\ \\ \sqrt{3} = \frac{5\sqrt{3}}{w} \\ \\ w = \frac{5 \cancel {\sqrt{3}} }{ \cancel {\sqrt{3}} } \\ \\ w = 5[/tex]
Matt paid $450 in interest on a 15 month note for
$5600. Find the rate of interest paid.
Answer:
The rate is 6.43%
Step-by-step explanation:
Given
[tex]I = 450[/tex] --Interest
[tex]P = 5600[/tex] -- Principal
[tex]T= 15\ months[/tex] --Time
Required
Determine the rate
Using simple interest formula:
[tex]I = PRT[/tex]
Make R the subject
[tex]R = \frac{I}{PT}[/tex]
Convert time to years
[tex]T= 15\ months[/tex]
[tex]T =\frac{15}{12}\ years[/tex]
[tex]T =1.25\ years[/tex]
Substitute values for I, P and T
[tex]R = \frac{450}{5600*1.25}[/tex]
[tex]R = \frac{450}{7000}[/tex]
[tex]R = 0.0643[/tex]
Convert to percentage
[tex]R = 0.0643*100\%[/tex]
[tex]R = 6.43\%[/tex]

In the mid term test Jesse scored 92%,89% and 90%.What was her main score
Answer:
100%
Step-by-step explanation:
Answer:
90.3%
Step-by-step explanation:
I think you have a typo. I'm pretty sure you meant mean score. To find the mean, we add up all the values and divide by the number of values. Let's add 92, 89, and 90. That gets us 271. Now, let's divide 271 by 3. That gets us 90.3. That means Jesse's mean score is 90.3%.

10. Peter had a policy with a $250 deductible which paid 80% of his covered charges less deductible. He had medical expenses of $18,240.00. What is the insurance company's payment?
O $14,392
O $14,300
O $250
O $15,000
Answer:
$14392
Step-by-step explanation:
The insurance company's payment is $14392. which is the correct answer would be an option (A).
What is the percentage?The percentage is defined as a ratio expressed as a fraction of 100.
The required insurance company's payment is the difference between 80% of medical expenses and 80% of the deductible amount.
According to the given question, the required solution would be as:
The insurance company's payment = 80% of $18,240.00 - 80% of $250
The insurance company's payment = (80/100)18,240.00 - (80/100)250
The insurance company's payment = (0.80)18,240.00 - (0.80)250
The insurance company's payment = 14592 - 200
Apply the subtraction operation,
The insurance company's payment = $14392
Therefore, the insurance company's payment is $14392. which is the correct answer would be an option (A).

Answer:
AE = CE = 23; BE = DE = 20
Step-by-step explanation:
Put the values of the variables in their place and do the arithmetic.
AE = 2u+5 = 2(9) +5 = 23
BE = 6v-1 = 6(3.5) -1 = 20
CE = 3u-4 = 3(9) -4 = 23
DE = 8v-8 = 8(3.5) -8 = 20
The diagonals cross at their midpoints, so the quadrilateral is a parallelogram.
What is the length of the segment shown below. Round your answer to the nearest hundredth. (2,5) (-4,-1)
Answer:
Step-by-step explanation:
use the distance formula Emily P1=(x1,y1)=(2,5) P2=(x2,y2)=(-4,-1)
d = [tex]\sqrt{(x2-x1)^{2}+ (y2-y1)^{2} }[/tex]
d = [tex]\sqrt{6^{2}+ 6^{2} }[/tex]
d = 8.48528
d = 8.49

If (-x^2 + y^2) is subtracted from (x^2 + y^2), the difference is
A.2x^2
B.0
C. -2x^2
D. —2x^2– 2y^2
Answer:
If [tex](-x^2 + y^2)[/tex] is subtracted from [tex](x^2 + y^2)[/tex], the difference is: [tex]\mathbf{2x^2}[/tex]
Option A is correct option.
Step-by-step explanation:
If [tex](-x^2 + y^2)[/tex] is subtracted from [tex](x^2 + y^2)[/tex], we need to find the difference.
When finding the difference the term after from comes first.
We can write:
[tex](x^2 + y^2)-(-x^2 + y^2)[/tex]
Now finding difference:
Multiply minus sign with terms inside the bracket
[tex]=x^2 + y^2+x^2 - y^2[/tex]
Now combine the like terms
[tex]x^2 +x^2+ y^2 - y^2\\=2x^2+0\\=2x^2[/tex]
So, If [tex](-x^2 + y^2)[/tex] is subtracted from [tex](x^2 + y^2)[/tex], the difference is: [tex]\mathbf{2x^2}[/tex]
Option A is correct option.
HELP ASAP HELP NEEDED WILL MARK BRAINIEST
Answer:
No
Step-by-step explanation:
The height of the chair can be represented as a function of the height of table, if there is a constant variation between both heights. That is as one height increases, the other height decreases at the same proportion.
From the table, as the table height increases from 71 to 72 to 74 to 75, the chair height increases from 42 to 43 to 44 to 46. There is a direct variation but it is not constant. From 71 to 72, the height of table increases by 1 cm but from 74 to 75, the height increases by 2 cm.
Hence the height of the chair can not be represented as a function of the height of table
