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]
The area is 50.24 cm.
The formula is π·r^2.
The radius is 4 cm, and you square it. 16 cm.
Then you multiply 16 by 3.14 (π). And you get 50.24 cm as the area.
The correct answer is: [C]: " (0, 24) " .

Given the quadratic function:
___________________________________________________________
→ " y = (x <span>− 8) (x + 3) " ; </span>← Note: Replace the "f(x)" with: "y" ;
→ Find the "y-intercept".
___________________________________________________________
→ Note: The "y-intercept" is the coordinate of the point(s) of the graph of the equation at which the graph crosses the "x-axis" when "x = 0" .
→ So; we set plug in "0" for "x" into our equation; and solve for "y" ;
→ " y = (x − 8) (x + 3) " ;
→ y = (0 − 8) (0 + 3) ;
→ y = (-8) * (3) ;
→ y = - 24 ;
___________________________________________________________
So, the "y -intercept" of the <em><u>given</u></em> quadratic function is:
the point at which: "x = 0 ; y = -24 " ;
→ that is; the point the coordinates: " (0, - 24) " ;
___________________________________________________________
→ which is: Answer choice: [C]: " (0, - 24) " .

Answer: -8
Step-by-step explanation:
if y=6x+(-2), than y= 6x-2
if x=-1 we will replace x with this value
y=6(-1)-2=-6-2=-8
