Answer:
$7.60
Step-by-step explanation:
Use a linear function (again)
let x = peanuts
let y = almonds
3x+4y=27.45
5x+2y=24.05
Multiple 2nd equation by 2
3x+4y=27.45
10x+4y= 48.1
7x=20.65
x=2.95
Plug in x into either equation
10x+4y= 48.1
29.5+4y=48.1
4y=18.6
y=4.65
4.65+2.95=7.60
Answer:
the answer of the question is C because 1/2=.5
1. <span>-0.9x+2.8=4.1
First subtract 2.8 from both sides.
-0.9x = 1.3
Now divide both sides by -0.9.
x = -1.4444..
This can be rounded to -1.44
</span><span>c) -1.44
2. Jordan has 650 pennies. He'll give 85 to his brother and split the rest with his sister.
</span>d) 85+2x=650
Answer:
a. y^ -1 = e^x +2
Step-by-step explanation:
y = ln (x-2)
Exchange x and y
x = ln (y-2)
Solve for y
Raise each side with a base of e
e^ x = e^(ln(y-2)
e^x = y-2
Add 2 to each side
e^x +2 =y
