Answer:
(-1,5)
(3, 1/125)
Step-by-step explanation:
g(x) = (1/5) ^x
Lets check the points
(1,0)
0 = (1/5) ^1
0 = 1/5 False this is not on the graph
(-1,5)
5 = (1/5) ^ -1
Remember negative exponents flip the fraction inside the parentheses
5 = 5/1 True this is on the graph
(3, 1/125)
1/125 = (1/5)^ 3
1/125 = 1^3/ 5^3
1/125 = 1/125 true this is on the graph
(-2,1/25)
1/25 = (1/5) ^-2
Remember negative exponents flip the fraction inside the parentheses
1/25 = 5^2/1^2
1/25 = 25 false this is not on the graph
Answer:
The system of equations is given as:
x + y = 2.5 .... Equation 1
1.8x + 1.8y = 4.05....Equation 2
Step-by-step explanation:
Kiran says, "I bought 2.5 pounds of red and yellow lentils. Both were $1.80 per pound. I spent a total of $4.05
Let
x represent red lentils
y represent yellow lentils.
x + y = 2.5 .... Equation 1
x = 2.5 - y
$1.80 × x + $1.80 × y = $4.05
1.80x + 1.80y = 4.05....Equation 2
The system of equations is given as:
x + y = 2.5 .... Equation 1
1.8x + 1.8y = 4.05....Equation 2
Basically your just swapping there positions like so:
if x=-5, then 3-2x=13
Hope this helps! :)
