this should work because (4+4)+(-9+1)=0 an
im sorry if this is wrong but im 99% sure this is right
i only put things in parenthesis to make things work better in my brain
Answer:
m = -2
Step-by-step explanation:
4 + 4{m + 1} = 0 {Subtract 4 form both sides}
4{m + 1} = -4
4m + 4 = -4 {Subtract 4 form both sides}
4m = -4 - 4
4m = -8 {Divide both sides by 4}
m = -8/4
m = -2
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

What is the slope of a line perpendicular to the line whose equation is 12x+2y=-1212x+2y=−12. Fully reduce your answer.
Answer:
In this case the slope of a line perpendicular to the line whose equation is 12x+2y=-12 will be [tex]\frac{1}{6}[/tex]
Step-by-step explanation:
A line has the form:
y = m * x + b
where:
m is the slope of the line. b is Y-intercept. This is the value of y where the line crosses the y-axis.In this case, the line has the form 12*x+2*y=-12
First, you must isolate the variable "y", in order to arrive at the form of the line detailed above:
12*x+2*y=-12
2*y= -12 -12*x
y= (-12 -12*x)÷2
y= (-12)÷2 -(12÷2)*x
y= -6 -6*x
In this case: the slope is -6 and the Y-intercept is -6.
Two lines are perpendicular when they form four equal 90º angles. For two lines to be perpendicular, they must have their slopes inverse and changed sign.
Then, in this case the slope of a line perpendicular to the line whose equation is 12x+2y=-12 will be [tex]\frac{1}{6}[/tex]

Answer:
x ≈ 14.7
Step-by-step explanation:
use pythagorean therorem
a^2 + b^2 = c^2
c is hypotenuse and we know the hypotenuse is 21
a^2 + b^2 = c^2
x^2 + 15^2 = 21^2
x^2 + 225 = 441
x^2 = 216
x = √216
x ≈ 14.7

Step-by-step explanation:
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).

Statement: 4x < 0
Which is greater? 1 or x
Answer:
1 is greater than x
Step-by-step explanation:
4x < 0
x<0-4
x< -4
x={ -5,-6,-7,-8,-9,-10,.............}
so {-5,-6,-7,-8,-9,-10,-.............} are lesser than 1
hence 1 >x 0r 1 is greater than x
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.

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

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.

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
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
