Answer:
1) Subtraction Property of Equality
2) Multiplication Property of Equality
3) Addition Property of Equality
4) Division Property of Equality
Step-by-step explanation:
We proceed to present the correct answer to this question and explain the reason behind the election of each option below:
1) [tex](6+3)-3 = 9 - 3[/tex] Subtraction Property of Equality
Reason - Subtraction is a particular form of addition based on the consideration of the existence of additive inverses. The subtraction property of equality is defined as: [tex]a = b[/tex] if and only if [tex]a+(-c) = b+(-c)[/tex].
2) [tex](6+3)\times 3 = 9 \times 3[/tex] Multiplication Property of Equality
Reason - The multiplication property of equality is defined as: [tex]a = b[/tex] if and only if [tex]a\cdot c = b\cdot c[/tex].
3) [tex](6+3)+3 = 9+3[/tex] Addition Property of Equality
Reason - The addition property of equality is defined as: [tex]a = b[/tex] if and only if [tex]a+c = b+c[/tex].
4) [tex](6+3)\div 3 = 9 \div 3[/tex] Division Property of Equality
Reason - The division is a particular form of multiplication based on the consideration of the existence of multiplicative inverses. The division property of equality is defined as: [tex]a = b[/tex] if and only if [tex]a\cdot c^{-1} = b\cdot c^{-1}[/tex].

similarity statement for the two triangles?
In rhombus ABCD, AC = 18, and BD = 24, what is the
length of one side of the rhombus?
B
1) 30
2) 42
3) 15
4) 21
Answer:
15
Step-by-step explanation:
Here, given the diagonals of the Rhombus, we want to get the length of one side of the Rhombus
We proceed to use the formula below;
d1 = √(4a^2-d2^2
Where d1 represents the length of one diagonal
a is the side of the Rhombus
d2 is the length of the second diagonal
Thus, mathematically;
d2^2 = 4a^2 - d1^2
4a^2 = d2^2 + d1^2
4a^2 = 18^2 + 24^2
4a^2 = 900
a^2 = 900/4
a^2 = 225
a = √225
a = 15

1. Use the distance formula (FOR COORDINATES) to find the distance between A(-6, 4) and B(5,-3).
Answer: [tex]\sqrt{170}[/tex]
Step-by-step explanation:
Distance formula: a^2+b^2=c^2 where c is the distance between two points
(-6-5)^2 + (4-(-3))^2=c^2
(-(6+5))^2 + (4+3)^2=c^2
(-11)^2 + 7^2=c^2
121 + 49=c^2
c^2=170
c=[tex]\sqrt{170}[/tex] ==> distance between A and B
Solve: 8 + b/2 = 14 HELPPPPPPPPPPPPPPPPP
Answer:
b = 12
Step-by-step explanation:
subtract eight from both sides to leave the b variable on the left
b/2 = 14 - 8
b/2 = 6
multiply by 2 on both sides to leave b by itself
b = 6 * 2
b = 12
Answer:
12
Step-by-step explanation:
8 + b/2 = 14
b/2 = 14 -8
= 6
b = 6 x 2
= 12
Therefore b is 12. Hope this helps you and pls mark me as brainliest <3

There is a line whose y intercept is 3 and whose slope is 6. What is its equation in slope-imtercept form?
Write your answer using integers, proper fractions, and improper fractions in simplest form.
Answer:
y = 6x + 3
Step-by-step explanation:
Equation of the line
------------------------------------------------------
The equation of the line in slope-intercept form is:
y = mx + b
Being m the slope and b the y-intercept.
Where m is the slope and (h,k) is a point through which the line passes.
We are given the y-intercept as b=3 m=6.
Thus, the equation of the line is:
y = 6x + 3

An airplane descends at a rate of 2,700 feet per minute. once the airplane starts its descent, what will be its change in elevation after 312minutes?
The airplane that descends at a rate of 2,700 feet per minute, after 3 1/2 minutes it will be at 9450 ft
The formula and procedure we will use to solve this problem is:
v= x/t
Where:
x = distancet = timev = velocityInformation about the problem:
x = ?t = 3 1/2 minv = 2,700 ft/minConverting the mixed fraction to a fraction, we get:
3 1/2 =
[(3*2) + 1]/2 =
(6+1) / 2 =
7/2
3 1/2 min is equivalent to 7/2
Applying the velocity and isolating the distance we have:
x= v*t
x = 2700 ft/min * 7/2 min
x = 9450 ft
What is velocity?It is a physical quantity that indicates the displacement of a mobile per unit of time, it is expressed in units of distance per time, for example (miles/h, km/h).

suppose that verania and josimar are roommates that need to complete some household chores. vacuuming and washing dishes need to be done. they know from the last time they did these chores that it takes verania 2 hours to vacuum and 1 hour to wash dishes. it takes josimar 3 hours to vacuum and 2 hours to wash dishes. josimar says it does not matter which task each of them performs because verania is faster at both tasks.
It is wrong. Because Verania has a comparative advantage in washing dishes, she should wash dishes, and Josimar should vacuum.
Having an absolute advantage in both things does not mean that Verania has a Comparative advantage in both as well.
They should find out which activity they both have a comparative advantage in and focus on that. The activity that costs the least opportunity cost is the one they have a comparative advantage.
Verania
Opportunity cost of vacuuming = 2 / 1 = 2 hours of washing dishes
Opportunity cost of washing = 1/2 = 0.5 hours of vacuuming
Josimar
The opportunity cost of vacuuming = 3/2 = 1.5 hours of washing dishes
Opportunity cost of washing = 2/3 = 0.66 hours of vacuuming
Verania has a comparative advantage in washing dishes while Josimar has a comparative advantage in vacuuming.

Form A polynomial whose real zeros and degree are given.
What polynomial has zeros of -5,-1.2,5 and degree of 4?
The polynomial function has zeroes as given by x=0
In general, given zeroes of a polynomial function, a, b, c, and d, we can write the function as the multiplication of the factors
(x-a), (x-b), (x- c), and (x-d) then the degrees are 4
simply:
f(x)=(x-a) (x-b) (x- c) (x-d)
In this case, we can show that each of a, b, c, and d are zeroes of the function:
f(a)=(a-a) (a-b) (a-c) (a-d)
= (0) (a-b) (a-c) (a-d)
=0
f(b)=(b-a) (b-b) (b-c) (b-d)
=(b-a) (0) (b-c) (b-d)
=0
f(c)=(c-a) (c-b) (c-c) (c-d)
=(c-a) (c-b) (0) (c-d)
=0
f(d)=(d-a) (d-b) (d-c) (d-d)
=(d-a) (d-b) (d-c) (0)
=0
since the value of the function at x=a, x=b, c, and d are equal to 0, then the function
f(x)=(x-a) (x-b) (x- c) (x-d) has zeroes at a, b, c and d
with the generalized form, we can substitute for the given zeroes,
x=-5, x=-2,0and 5 where a=-5, b=-2, c=0 and x=5
f(x)=(x-(-5)) (x-(-2)) (x-0) (x-5)
simplifying gives:
f(x)=(x+5) (x+2) x(x-5)
from here, we can put it in standard polynomial form by foiling the right side:
f(x)=x^3+2x^2-25x-50
To double-check the answer, just plug in the given zeroes, and ensure the value of the function at those points is equal to 0.
f (-5) =x^3+2x^2-25x-50
=(-5)^3+2(-5)^2-2(-5)-50
f (-5) =0
f (-2) =(-2)^3+2(-2)^2-2(-2)-50
f (-2) =0
f (0) =0
f (5) =(5)^3+2(5)^2-2(5)-50
=0
Hence, the function has zeroes as given by x=0.

Solve the System of Equations using Substitution or Elimination. State your final
answer as an ordered pair (x,y) *
-3x + 10y = -15
5x - 7y = -4
Answer:
(- 5, - 3 )
Step-by-step explanation:
Given the 2 equations
- 3x + 10y = - 15 → (1)
5x - 7y = - 4 → (2)
Multiplying (1) by 5 and (2) by 3 and adding the result, eliminates the x- term.
- 15x + 50y = - 75 → (3)
15x - 21y = - 12 → (4)
Add (3) and (4) term by term to eliminate x, that is
29y = - 87 ( divide both sides by 29 )
y = - 3
Substitute y = - 3 into either of the 2 equations and solve for x
Substituting into (1)
- 3x + 10(- 3) = - 15
- 3x - 30 = - 15 ( add 30 to both sides )
- 3x = 15 ( divide both sides by - 3 )
x = - 5
solution is (- 5, - 3 )
