Step-by-step explanation:
[tex]2 {x}^{2} + 4x + 4 + {x}^{2} + 1 = 180[/tex]
[tex]3 {x}^{2} + 4x + 5 = 180[/tex]
[tex] {3x}^{2} + 25x - 21x - 175 = 0[/tex]
[tex]x \times (3x + 25) - 7(3x + 25) = 0[/tex]

What is the rate of change of y=-50+31
Hey there!
Guide:
• Negatives are on the LEFT side of the number line
• Positives are on the RIGHT side of the number line.
• Negatives are BELOW 0 (less than 0)
• Positives are ABOVE 0 (more than 0)
• You have to take the value of the LARGER number.
• If your LARGER number is a negative number then your result will be a negative.
• If your LARGER is a positive number then your result will be a positive
• Negative & Negative = Positive
• Negative & Positive = Negative
• Positive & Positive = Positive
• Positive & Negative = Negative
y = -50 + 31
• So, you start from -50 and go UP 31 spaces to the right because “31” is a positive number.. once when you have moved UP your 31 spaces you have reached your answer for this given equation
y = -50 + 31
y = -19
Therefore, your answer is: y = -19
Good luck on your assignment and enjoy your day!

For what values of x is the equation X^2-x=20 true?
Answer: x = 5 or x = -4
Step-by-step explanation:
Given equation
x² - x = 20
Subtract 20 on both sides
x² - x - 20 = 0
Cross factorize the equation
x -5
x 4
Factorize the equation
(x - 5) (x + 4) = 0
[tex]\boxed{x=5}[/tex] or [tex]\boxed{x=-4}[/tex]

A baseball team won 16 games and lost 11. At this rate, how many games will it win in a 162-game schedule?
==========================================================
Explanation:
The team won 16 games and lost 11 so far. At this point in the season, they played 16+11 = 27 games total. Their win rate is 16/27.
Set this equal to x/162 which is the win rate for winning x games out of 162 played over the entire season.
Solve for x.
x/162 = 16/27
27x = 162*16 ... cross multiplication
27x = 2592
x = 2592/27
x = 96
The team would win 96 games if it kept the same winning rate going.
Notice that 16/27 = 0.5926 = 59.26% and how 96/162 = 0.5926 = 59.26% as well (both are approximate). This helps confirm we have the correct answer.
-------------------------
Here's another slightly longer way to solve. If you prefer the first method above, then ignore this section.
w = number of games won over the entire 162 game season
162-w = number of games lost over the entire season
w/(162-w) = win to loss ratio
16/11 = win to loss ratio after winning 16 games and losing 11
Setting those last two expressions equal to each other and solving for w gets us...
w/(162-w) = 16/11
11w = 16(162-w)
11w = 2592-16w
11w+16w = 2592
27w = 2592 ... this hopefully looks a bit familiar from before
w = 2592/27
w = 96 games won

7×2.5=17.5
Answer:
4/7=10/x
or, 4×x=10×7
or, 4x=70
or, x = 70/4
or, x = 17.5
Thus, x is 17.5

Perform the indicated operations. Write the answer in standard form, a+bi.
(9 + 2i)(9 - 2i)
Answer:
It can't be expressed in that form
Step-by-step explanation:
From difference of two squares:
[tex]{ \boxed{(a + b)(a - b) = ( {a}^{2} - {b}^{2} )}}[/tex]
a » 9
b » 2i
[tex](9 + 2i)(9 - 2i) = \{ {(9)}^{2} - {(2i)}^{2} \} \\ \\ = (81 - 4 {i}^{2} )[/tex]
but i² is -1 [ complex numbers ]
[tex] = \{81 - 4( - 1) \} \\ = 81 + 4 \\ = 85[/tex]
Answer:
[tex](9 + 2i)(9 - 2i) \: \\ this \: can \: be \: wrtten \: as \: \\ {9}^{2} - {2i}^{2} = 81 - 4 \times - 1 \\ = 81 + 4 = 85 \\ then \: 85 + 0i \\ thank \: you[/tex]

Jillian simplified the expression 7 + 3 . (10 -6) ^2 in the following way:
7 + 3 . (10 - 6) ^2
7+ 3 . (4)^2
7+3 . 16
10 . 16
160
Part: A Explain, using the complete sentences, what Jillian’s error was
Part B: show how the expression should have bee simplified using a similar format.
Please help me how should I explain it
Answer:
Part A: Jillian added 7+3 first rather than multiplying 3*16 b/c multiplication comes before addition
Part B:
7 + 3 * (10 - 6) ^2
7+ 3 * (4)^2
7+3 * 16
7 + 48
55
Step-by-step explanation:
Answer:
Part A:
Jillian's error was that they added the 7 and the 3 to get 10 and then multiplied by 16. Jillian should have multiplied the 3 and the 16 first and then added 7. This is because multiplication comes before addition in PEMDAS.
Part B:
7+3×(10-6)^2
7+3×(4)^2
7+3×16
