2.)161
3.)cz
Step-by-step explanation:
2.) 81^2-80^2
(81+80)(81-80)

Step-by-step explanation:
The equation 4(−2)=1004(−2)=100 is a true equation for a specific value of x. Explain why 2(−2)=502(−2)=50 is also true for the same value of x.
because it halves: 4 ----> 2 so the result also halves ( 1004:2=502 and 100:2=50 )

Find the distance, to the nearest hundredth, between p1 (-3,-2) and p2 (9,3)
Answer:
[tex]d = 13[/tex]
General Formulas and Concepts:
Order of Operations: BPEMDASDistance Formula: [tex]d = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]Step-by-step explanation:
Step 1: Define
P1 (-3, -2)
P2 (9, 3)
Step 2: Find distance d
Substitute: [tex]d = \sqrt{(9-(-3))^2+(3-(-2))^2}[/tex]Simplify: [tex]d = \sqrt{(9+3)^2+(3+2)^2}[/tex]Add: [tex]d = \sqrt{(12)^2+(5)^2}[/tex]Evaluate: [tex]d = \sqrt{144+25}[/tex]Add: [tex]d = \sqrt{169}[/tex]Evaluate: [tex]d = 13[/tex]The measures of two vertical angles are 33° and (2x + 3)°. Find the value of x.
Answer:
x = 6
Step-by-step explanation:
If we replace x with 6, we will get 33 degrees. 33 = 33. They are equivalent.
(2*6+3)= 33.
So, x = 6 for both angles to be the same.
I hope this helps you!
4(x-3)= -3x + 23 show your work
Answer:
x = 5
Step-by-step explanation:
Expand the brackets
4x - 12 = -3x + 23
Rearrange by collecting the like terms, so that the variables are on one side and the constants are on the other
4x + 3x = 23 + 12
7x = 35
Divide both sides by 7 to make variable on its own
x = 35/7
x = 5
Answer:
x=5
Step-by-step explanation:
4 • (x - 3) - (23 - 3x) = 0
7x - 35 = 7 • (x - 5)
7 • (x - 5) = 0
7 = 0
x-5 = 0
x = 5
Determine whether each trinomial is a perfect square or not.. 1.A2+2a+1 2.4+4a+a2 3.A2-3a+9 4.4a2+24a+36 5.A4-10a+25 6.25a2+20a+9 7.A2b2-14ab+49 8.A2-2a-1 9.16a2+24a+36 10.10+6a+a2
Answer:
1) Perfect square, 2) Perfect square, 3) Not a perfect square, 4) Perfect square, 5) Perfect square, 6) Not a perfect square, 7) Perfect square, 8) Not a perfect square, 9) Not a perfect square, 10) Not a perfect square.
Step-by-step explanation:
From Algebra we must remember that a trinomial is a perfect square if and only if:
[tex](a+b)^{2} = a^{2}+2\cdot a\cdot b + b^{2}[/tex], [tex]\forall \,a,b\in\mathbb{R}[/tex] (Eq. 1)
Now we proceed to prove each trinomial:
1) [tex]a^{2}+2\cdot a +1[/tex]:
If [tex]a^2 =a^2[/tex] and [tex]b^{2} = 1[/tex], then [tex]a = \pm a[/tex] and [tex]b =\pm 1[/tex]. Therefore, [tex]2\cdot a\cdot b = 2\cdot (\pm a)\cdot (\pm 1) = \pm 2\cdot a[/tex]. In a nutshell, we conclude that this polynomial is a perfect square.
2) [tex]4+4\cdot a +a^{2}[/tex]
If [tex]a^{2} = 4[/tex] and [tex]b^{2} = a^{2}[/tex], then [tex]a = \pm 2[/tex] and [tex]b = \pm a[/tex]. Therefore, [tex]2\cdot a \cdot b = 2\cdot (\pm 2)\cdot (\pm a) = \pm 4\cdot a[/tex]. In a nutshell, we conclude that this polynomial is a perfect square.
3) [tex]a^{2}-3\cdot a +9[/tex]
If [tex]a^{2} = a^{2}[/tex] and [tex]b^{2} = 9[/tex], then [tex]a = \pm a[/tex] and [tex]b = \pm 3[/tex]. Therefore, [tex]2\cdot a \cdot b = 2\cdot (\pm a)\cdot (\pm 3) = \pm 6\cdot a[/tex]. In a nutshell, we conclude that this polynomial is not a perfect square.
4) [tex]4\cdot a^{2}+24\cdot a + 36[/tex]
If [tex]a^{2} = 4\cdot a^{2}[/tex] and [tex]b^{2} = 36[/tex], then [tex]a = \pm 2\cdot a[/tex] and [tex]b = \pm 6[/tex]. Therefore, [tex]2\cdot a \cdot b = 2\cdot (\pm 2\cdot a)\cdot (\pm 6) = 24\cdot a[/tex]. In a nutshell, we conclude that this polynomial is a perfect square.
5) [tex]a^{4}-10\cdot a +25[/tex]
If [tex]a^{2} = a^{4}[/tex] and [tex]b^{2} = 25[/tex], then [tex]a = \pm a^{2}[/tex] and [tex]b = \pm 5[/tex]. Therefore, [tex]2\cdot a \cdot b = 2\cdot (\pm a^{2})\cdot (\pm 5) = \pm 10\cdot a^{2}[/tex]. In a nutshell, we conclude that this polynomial is a perfect square.
6) [tex]25\cdot a^{2}+20\cdot a + 9[/tex]
If [tex]a^{2} = 25\cdot a^{2}[/tex] and [tex]b = 9[/tex], then [tex]a = \pm 5\cdot a[/tex] and [tex]b = \pm 3[/tex]. Therefore, [tex]2\cdot a \cdot b = 2\cdot (\pm 5\cdot a)\cdot (\pm 3) = \pm 30\cdot a[/tex]. In a nutshell, we conclude that this polynomial is not a perfect square.
7) [tex]a^{2}\cdot b^{2}-14\cdot a \cdot b + 49[/tex]
If [tex]a^{2} = a^{2}\cdot b^{2}[/tex] and [tex]b^{2} = 49[/tex], then [tex]a = \pm a\cdot b[/tex] and [tex]b = \pm 7[/tex]. Therefore, [tex]2\cdot a\cdot b = 2\cdot (\pm a\cdot b)\cdot (\pm 7) = \pm 14\cdot a \cdot b[/tex]. In a nutshell, we conclude that this polynomial is a perfect square.
8) [tex]a^{2}-2\cdot a -1[/tex]
If [tex]a^{2} = a^{2}[/tex] and [tex]b^{2} = -1[/tex], then [tex]a = \pm a[/tex] and [tex]b = \pm i[/tex]. Therefore, [tex]2\cdot a \cdot b = \pm 2\cdot a \cdot i[/tex]. In a nutshell, we conclude that this polynomial is not a perfect square.
9) [tex]16\cdot a^{2} + 24\cdot a +36[/tex]
If [tex]a^{2} = 16\cdot a^{2}[/tex] and [tex]b^{2} = \pm 36[/tex], then [tex]a = \pm 4\cdot a[/tex] and [tex]b = \pm 6[/tex]. Therefore, [tex]2\cdot a \cdot b = 2\cdot (\pm 4\cdot a)\cdot (\pm 6) = \pm 48\cdot a[/tex]. In a nutshell, we conclude that this polynomial is not a perfect square.
10) [tex]10+6\cdot a +a^{2}[/tex]
If [tex]a^{2} = 10[/tex] and [tex]b^{2} = a^{2}[/tex], then [tex]a = \pm\sqrt{10}[/tex] and [tex]b = \pm a[/tex]. Therefore, [tex]2\cdot a \cdot b = \pm 2\cdot \sqrt{10}\cdot a[/tex]. In a nutshell, we conclude that this polynomial is not a perfect square.

Answer:
-1/9
Step-by-step explanation:
Answer:
Hi there your answer is -0.1 or -1/9
Step-by-step explanation:
You have to use pemdas so you start with parenthesis.
(-15/2)= -7.5.
Then, rewrite the equation so 5/6/-7.5.
5/6/-7.5= -0.1 or -1/9

1. Ms. Thomas took her family and friends to the movies. There were a total of 16 people. Children's tickets cost $6 and adult tickets cost $9. She spent a total of $129. How many adults went to the movies?
2. Last season two running backs on the college football team rushed for a combined 1550 yards. One rushed 4 times as many yards as the other. How many yards did the player with the most yards rush?
A)
9*13+6*2=129
117+12=129
13 adults went to the movies
B)
1550/5=310
runner A ran four times as much as runner b
given the above, runner A ran 4*310 and B ran 310, since 1550/5=310
4*310=1240
The player with the most yards (runner A) ran 1240 yards
The school store earned $625.32 one week, and then $98.36, $145.98, and $304.09 during the next three weeks. How much did the school store earn in the four weeks?
Answer:
The store earned $1173.75 in the 4 weeks
Step-by-step explanation:
To calculate the amount earned by the school in the 4 weeks, we are going to add all what had been earned in the previous weeks;
Mathematically that would be;
$625.32 + $98.36 + $145.98 + $304.09 = $1,173.75

Write an equation that represents the line.
Use exact numbers.
Answer:
y = 5/6x + 2.5
Step-by-step explanation:
slope = m = rise/run
equation format - y=mx+b
slope/m= 5/6
y=5/6x+ the y-intercept
the y-intercept is at 2.5
so the full equation would be \/\/\/
y = 5/6x + 2.5
Find m< s
Please please help
Answer:
m< s = 43
Step-by-step explanation:
77 + 2x + 3 = 6x (collect like terms)
80 + 2x = 6x (subtract 2x on both sides)
80 = 4x (divide both sides by 4)
20 = x
PLUG IN TO M<S
2(20) + 3
40 + 3
m<s = 43
