Answer:
Potato price = $1.5 / pound ; Carrot price = $1.75 / pound
Step-by-step explanation:
Let price of carrot per pound = c
Let price of potatoes per pound = p
Given :
2c + 3p = 8 (eqtn A)
4c + 4p = 13 (eqtn B)
Multiplying eqtn A by 2 ;
4c + 6p = 16
4c = 16 - 6p (eqtn Y)
By eqtn B ;
4c = 13 - 4p (eqtn Z)
By eqtn Y & Z ;
16 - 6p = 13 - 4p
16 - 13 = - 4p + 6p
3 = 2p
p = 3 /2
p = 1.5 [Potato price]
Putting p value in eqtn A
2c + 3 (1.5) = 8
2c + 4.5 = 8
2c = 8 - 4.5
2c = 3.5
c = 3.5 / 2
c = 1.75 [Carrot Price]
Answer:
b=-0.0019a + 215
at 2500 ft, b=210.25 degrees F
Step-by-step explanation:
First find the slope. a=altitude, b = temperature
slope is b2-b1 / a2-a1
points are (8200, 199.42) and (4700, 206.07)
(206.07 - 199.42) / (4700-8200)
= 6.65/ -3500
= - 0.0019
we have b = -0.0019a + intercept
plug in a point to find intercept
199.42 = -0.0019*8200 + intercept
intercept = 199.42 + 15.58 = 215
b=-0.0019a + 215
at a=2500 ft, substitute into equation
b= -0.0019*2500 + 215
= -4.75 + 215
= 210.25 degrees F

Answer:
y = -1/4x - 2
Step-by-step explanation:
I'm going to write this equation in slope intercept form, which looks like this: y = mx + b. First, write the equation using the slope given. It should look like this:
y = -1/4x + b
Next, you must find the y intercept by plugging in the point to the equation. This is what it looks like: 0 = -1/4(-8) + b. Multiply -1/4 by -8 to get 2. This is what your equation should look like now: 0 = 2 + b. Subtract 2 from both sides of the equation to get -2 = b. Go back to your original equation and plug -2 in for b. This is your final equation:
y = -1/4x - 2
