Slope =  (3 - (-5)) /  (-8-2) =  8/-10 = -4/5

y = -4/5x + b    where b = slope intercept

when x = 2 y = -5 so:-

-5 = -4/5 * (2) + b

b =  -5 + 8/5 =  

Equation is  y = -4/5 x - 17/5     answer

First find the slope: Y2-Y1/X2-X1 =-4/5 Then plug in 1 y coordinate and x coordinate to the equation: Y=mx+b Y=-4/5x +b Y=-4/5x-17/5

F(x) = -2x²-2x+10, find f(2)
beks73 [17]

Answer:

f(2) = -2

Step-by-step explanation:

Substitute 2 everywhere you see an x so f(2) = -2(2^{2}) - 2(2) + 10 so

f(2) = -2(4) - 4 + 10, so f(2) = -8-4+10, f(2) = -12+10, f(2) = -2

A sales person earns a commission based on the number and type of vehicle sold. A person selling 6 cars and 3 trucks earns 4,800
AURORKA [14]
Assign variables to you unknowns.

c = $ cars
t = $ trucks

6c + 3t = 4800
8c + t = 4600

use substitution or elimination to solve the system of equations.

using elimination.. multiply second equation by -3 and add to the other to combine equations into one.

6c + 3t = 4800
-3(8c + t = 4600)
---------------------------
-18c + 0 = -9000
c = 9000/18
c = 500 $

use this in one of the equations to find the cost of a truck.

8(500) + t = 4600
4000 + t = 4600
t = 4600 - 4000
t = 600 $

question asks
2(500) + 3(600) =
1000 + 1800 = 2800 $
