Part A) If would probably be smart to use substitution because y is already solved for, so we can substitute the value of y as a function of x into the other equation.
y=7x-8
y=5x-2
7x-8=5x-2
+8 +8
-----------------
7x=5x+6
-5x -5x
----------------
2x=6
/2 /2
-----------
x=3
y=7x-8
y=21-8
y=13
Part B) The lines will intersect at point (3, 13), because idk it just makes sense
Area of triangle = I/2*b*h
96 = I/2*b*8
96 = 4b
24in = b
Therefore perimeter = 24*3
= 72in
Answer:
P = -0.004Q + 149
Step-by-step explanation:
The general form of the linear equation is:
The slope of the equation (a) can be found by using the two given points (4,000; $133) and (27,000; $41)
Applying the point (4,000; $133) to the equation below yields in the linear equation for Price as a function of the number of shirts:
The linear equation is:
P = -0.004Q + 149
Answer:
a = 1/8
Step-by-step explanation:
2 is the x value and y =.5
Substitute this into the equation
f(x) = ax^2
.5 = a(2)^2
.5 = a 4
Divide each side by 4
.5/4 = 4a/4
1/8 = a
