Simple...

when they ask for the rate of change they ask for slope -->>

Using \frac{ y_{1} - y_{2} }{ x_{1} - x_{2} } to find the rate of change for (-3,0) and (-2,-5)

\frac{0--5}{-3--2}

\frac{0+5}{-3+2}

\frac{5}{-1}

m=-5 

Thus, your answer.

Which equation can be used to solve the following word problem? Seth has 8 more nickels than dimes, and the total value of his c
9966 [12]

Answer:

Seth has 21 nickels

Step-by-step explanation:

Let n represent the number of nickels. Since Seth has 8 more nickels than dimes, then (n-8) is the number dimes.

Nickel is worth 5 cents and dime is worth 10 cents.  Thus, n nickels are worth 5n cents and (n-8) dimes are worth 10(n-8) cents. The total value of Seth's coins is $2.35 that is 235 cents, then

5n+10(n-8)=235.

Solve this equation:

5n+10n-80=235,\\ \\15n=235+80,\\ \\15n=315,\\ \\n=21.

The graph of y = 1/2 x2 + 2x + 3 is shown. What are the solutions to the equation 1/2 x2 + 2x + 3 = x + 7?
kirill [66]

Answer:

Step-by-step explanation:

Let's organise our information :

  • the function is (1/2)x²+2x+3

we want to khow the value of x that gives us : (1/2)x²+2x+3=x+7

Now the trick is to write this expression as a quadratic equation with zero at one side :

  • (1/2)x²+2x+3=x+7
  • (1/2)x²+2x+3-x-7=0
  • (1/2)x²+x-4=0

Now let's solve this equation :

  • a= 1/2
  • b= 1
  • c= -4

Δ=1²-4*(1/2)*(-4)

 = 9

So we have two solutions :

  • \left \{ {{y=\frac{-1-3}{2*0.5} } \atop {x=\frac{-1+3}{2*0.5} }} \right.
  • y= -4
  • x= 2

So the solutions are -4 and 2

Televisions are on sale for 40% OFF the original price of $600. After tax (8.5%) is applied, what is the final price?​
FromTheMoon [43]

First, determine what is 40% of $600. Multiple 40 (as a decimal) by 600.

0.4 x 600 = 240

Therefore, the discount is $240 off $600.

Subtract the two values to find price (before tax): 600 - 240 = 360

So the TV will cost $360 before tax.

The tax is 8.5%. Multiply 8.5 as a decimal by 360 to find the amount of tax added.

0.085 x 360 = 30.6

Add 30.6 and the price before tax to find the final price.

30.6 + 360 = 390.60

Therefore, the final price of the TV is $390.60

A computer can process the payroll for Hometel in 10 hours. An older back up computer needs 11 hours to
dem82 [27]

Both computers will do the job in 5 hours and 14 minutes.

Since a computer can process the payroll for Hometel in 10 hours, while an older back up computer needs 11 hours to process payroll, to determine how long would the job take if the two computers are both used to do the job, the following calculation should be performed:

  • X / 10 + X / 11 = 1
  • 10X + 11X = 110
  • 21X = 110
  • X = 110/21
  • X = 5.238  
  • 100 = 60
  • 0.238 = X
  • 0.238 x 60/100 = X
  • 0.14 = X

Therefore, both computers will do the job in 5 hours and 14 minutes.
