Answer:
Before one can solve for the width of a rectangle(the value of the area or perimeter must be given and the length)
Using the area
Length = l
Width =w
Area = a
a = l × w ; a = lw
w = a/l
using perimeter(p)
p = 2(l+w)
p/2 = l+w
p/2 - l = w
w = p/2 -l
En un aeropuerto dos aviones A1 y A1 se acercan para aterrizar, si la ecuación de la trayectoria del primero es -x+2y-100=0, mientras que la ecuación de la trayectoria del segundo es de –x+200 +2y, determina si existe el riesgo de que sufran un choque entre ellos.
No hay solución en la que ambas trayectorias estén en la misma posición, puesto que no existe el riesgo de que sufran un choque entre ellos.
-------------------------
La trayectoria del primero es:
[tex]-x + 2y - 100 = 0[/tex]
[tex]x_1 = 2y - 100[/tex]
Para el segundo, tiene-se que:
[tex]-x + 200 + 2y = 0[/tex]
[tex]x_2 = 2y + 200[/tex]
Igualando los valores de x:
[tex]x_1 = x_2[/tex]
[tex]2y - 100 = 2y + 200[/tex]
[tex]0y = 300[/tex]
No hay solución en la que ambas trayectorias estén en la misma posición, puesto que no existe el riesgo de que sufran un choque entre ellos.

Answer:
a. $77.5 for 5 tickets
b. You can by 8 tickets with $130
Step-by-step explanation:
Answer:
a) $77.50
b) 8 tickets
Step-by-step explanation:
a) C(x) = 17.5(x) - 10
C = 17.5(5) - 10
C = $77.50
b) C(x) = 17.5(x) - 10
130 = 17.5(x) - 10
130 + 10 = 17.5(x) -10 + 10
140 = 17.5(x)
140/17.5 = (x)
8 = x

F(x) =2x-1 what is the value of f(x) when x = -1
Answer:
f(x) = -3 when x = -1
Step-by-step explanation:
Let's go through this!
So our equation is f(x) = 2x - 1
we are asked for the value of f(x) when x = -1
Let's consider this, the f(x) value is the y value
and the x value in f(x) is the x value
So when x = -1
what is the y value?
we can use the equation to subsitute -1 into x and solve for f(x)
f(x) = 2(-1)-1
f(x) = -3
Our answer is -3

What is a clock?A clock or a timepiece is a device used to measure and indicate time. The clock is one of the oldest human inventions, meeting the need to measure intervals of time shorter than the natural units such as the day, the lunar month and the year.
Now,
Time in Time out
7:05 2:58
7:30 5:01
8:01 4:32
7:22 4:46
6:55 3:31
Between 7:05 and 2:58 the number of hours is 7 hours 53 minutes
Between 7:30 and 5:01 the number of hours is 9 hours 31 minutes
Between 8:01 and 4:32 the number of hours is 8 hours 31 minutes
Between 7:22 and 4:46 the number of hours is 9 hours 24 minutes
Between 6:55 and 3:31 the number of hours is 8 hours 36 minutes
Now, (7+9+8+8+8)+(53+31+31+24+36)
= 40 hours + 175 minutes
= 40 hours + 2 hours 55 minutes
= 43 hours 55 minutes
= 44 hours
Therefore, the number of hours Janice worked in a week is 44 hours.

what is the multiplicative inverse of -3 1/2
A) 7/2
B) -2/7
C) 9
Answer:
B or -2/7 should be correct
Step-by-step explanation:
First, I would find out the improper fraction of -3 1/2
The improper fraction of -3 1/2 is -7/2
To find the multiplicative inverse, we will flip the numerator and the denominator.
Multiplicative inverse of -7/2 = 2/-7
2/-7 is a weird way to write a fraction, so to convert into a reasonable fraction, we will multiply both the numerator and denominator by -1.
2/-7 x -1/-1 = -2/7
Therefore, B should be your answer

I need a equation written for this pleeeeeaaaassse! The constant of proportionality is 2.
but I need an equation for this, I have an attachment for you to help. g= c is not correct sorry.
It sounds like your teacher wants g = 2c as the answer. The constant of proportionality simply tells us what to multiply the input variable by, to get the output variable.
It's similar to saying y = 2x, but we use c in place of x and use g in place of y.

Zachary purchased a new car for $29,995. The value of the car linearly depreciated to $9,300 over 10 years. Write a linear equation to represent the value y of Zachary's car (in dollars) after x years since its purchase.
Answer:
Step-by-step explanation:
y=-1,869.5x+27,995
Step-by-step explanation:
Let
x-----> the time in years
y----> value of Zachary’s car in dollars
A(0,27,995), B(10,9,300)
step 1
Calculate the slope
The formula to calculate the slope between two points is equal to
m=\frac{y2-y1}{x2-x1}
substitute
m=\frac{9,300-27,995}{10-0}=-1,869.50
step 2
Find the equation of the line
The equation of the line into slope intercept form is equal to
y=mx+b
we have
m=-1,869.50
b=27,995 -----> the y-intercept is the point A
substitute
y=-1,869.5x+27,995

find the sum of all possible four digit numbers that can be formed using the digits 2,4,5,6,7 and 8 with no repeated digits
Answer:
2133120
Step-by-step explanation:
using 6 given digits, lets create a 4 digit number:
to choose the first number, you have 6 options. to choose the second number we have 5 options left. for the third number we have 4 options left. and for the fourth number, we have 3 options left.
6*5*4*3 = 360
with no repeats, 360 numbers can be formed.
this means that each number will occur 60 times each (360/6 digits)
so to find the sum:
60*(2+4+5+6+7+8) = 1920
but, we have one more thing:
In the thousands place, our sum of digits is multiplied by 1000; in the 100’s place, by 100; in the ten’s place, by 10; and in the one’s place, by 1. so:
1920(1000+100+10+1) = 1920*1111 = 2133120
