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:
the answer is $40.5
Step-by-step explanation:
the basic formula of finding our interest is I = PxRxT
P (principal) = 675
R (rate) = 10% (we have to turn it into a decimal which is 0.010)
T (time) = 6 years
so :
I = 675 x 0.010 x 6
I = 40.5
Answer:
y = 0 and x = 6
y = 2 and x = 3
y = 4 and x = 0
y = 6 and x = -3
Step-by-step explanation:
2x+3y=12 is the equation of a straight line.
There are infinite number of solutions, but here you're probably looking for solutions where x and y are whole numbers. Trial and error will find you some, although if you examine the equation closely you see that if x is a multiple of 3 and y is a multiple of 2, then they produce terms that are the LCM (least common multiple) of 2 and 3, namely 6. That's the logic in the whole number solutions.
Answer:
Given the equation:
A quadratic equation is in the form: where a, b ,c are the coefficient and a≠0 then the solution is given by :
......[1]
On comparing with given equation we get;
a =3 , b = 10
then, substitute these in equation [1] to solve for c;
Simplify:
Also, it is given that the difference of two roots of the given equation is
i.e,
Here,
, ......[2]
.....[3]
then;
simplify:
or
Squaring both sides we get;
Subtract 100 from both sides, we get
Simplify:
-12c = -96
Divide both sides by -12 we get;
c = 8
Substitute the value of c in equation [2] and [3]; to solve
or
or
Simplify:
Now, to solve for ;
or
or
Simplify:
therefore, the solution for the given equation is: and -2.
