describe and find the slope of the line

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

the answer is : y - 5 = 6 ( x + 7)

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.

The number of hours Janice worked in a week is 44 hours.

Given that, Janice has recorded on her time sheet for the week.

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.

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

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

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

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.

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
