What property of operations can be used to justify that the two expressions in this equation are equivalent? 6x^2 +4x=4x + 6x^2
Answer:
Commutative
Step-by-step explanation:
There are four basic property of operations to solve an algebraic expressions. They are associative, commutative, distributive and identity.
The expression given is : [tex]$6x^2 + 4x=4x+6x^2$[/tex]
So the given algebraic expression is a commutative property of operations. The commutative property states that when any two numbers are added in an expression the sum of the numbers are the same regardless of the order of the numbers that are added.
Thus the sum of the above expression will be same in which ever order the numbers are added.

A bag contains 42 red, 45 green, 20
yellow, and 32 purple candies. You
pick one candy at random. Find the
probability that it is green or yellow.
Answer:
65/139 fraction form
0.47 decimal form
Answer:
Step-by-step explanation:
Total sample space , n (s) = 139
no of green candies , n (g) = 45
no. of yellow candies , n (y) = 20
Probability that is green or yellow is
P( g or y) = P(g) + P(y)
= n(g) / n(s) + n (y) / n(s)
= 45 / 139 + 20 / 139
= 65 / 139
hope it will help :)
Find the equation of a line that passes through the point (-2,-1) and is
perpendicular to the line with equation y = –2x+8.
Answer:
y=x/2
Step-by-step explanation:
If one line is perpendicular to another, then the product of their slope is -1.
y = –2x+8. This line has a slope of -2. Which means another line must have a slope of 1/2.
By knowing the slope, we then assume this line as x-2y=k. Insert the point in, we find out k=0.
So the equation of this line is x-2y=0, or y=x/2.

Why do interest rates on loans tend to be higher in a strong economy than in a weak one?
a. Credit markets increase in a strong economy, and with increased demand come
increased prices.
b A strong economy encourages borrowers to take out very long-term loans, which have
higher interest rates.
Credit is plentiful in a strong economy, so it is harder to build up the good credit rating
necessary for a low interest rate
d. People in a strong economy have more money, so they can afford more expensive loans.

Suppose it takes 2 1/2 h to drive from your house to the lake at 48 mi/h. How long will your return trip take at 40 mi/h?
Answer
The distance from the house to the lake is (2.5 hr)*(48 mi/hr) = 120 miles. The rerurn trip would take (120 mi)/(40 mi/hr) = 3 hours. Distance equals rate times time, so the distance to the lake is 2 1/2 hours times 48 miles per hour.

Answer:
co-terminal: 37°1st quadrantreference angle: 37°Step-by-step explanation:
-1043°/360° ≈ -2.9
Adding 3×360° will give a co-terminal angle in the range 0-360°:
-1043° +1080° = 37°
This co-terminal angle is in the first quadrant. It is also the reference angle.

Step-by-step explanation:
The leading non-zero digit must be move 15 places to the left to put it in the units place. Having done that, its original value will be restored by multiplying by 10^-15.
Rounded to 3 significant figures, 989912345 becomes 990. The trailing zero must be kept as part of the number to indicate that there are 3 significant figures.
In scientific notation, the number is ...

Additional comment
If the number can be copied and pasted to a spreadsheet, it can be formatted to scientific notation with the required number of digits. Here, we can't copy the number from the image, so we have marked off the decimal places in a way that makes them easier to count. Copying the given number text would avoid any transcription errors.

Write an equation that could be used to find the value of x using the interior angles of ∆BDC, then solve it.
9514 1404 393
Answer:
x = 16
Step-by-step explanation:
Either or both of the right triangles can be used to find x. Or, triangle ABC could be used. All numbers are assumed to be degrees.
Using ∆ABD
55 +90 +2x+3 = 180
2x = 32 . . . . . . subtract 148
x = 16
Using ∆BCD
50 +90 +2x+8 = 180
2x = 32 . . . . . . subtract 148
x = 16
Using ∆ABC
55 +(2x +3) +50 +(2x +8) = 180
4x = 64 . . . . . . . subtract 116
x = 16
