Answer:
x = -3 +/- square root(22)
Step-by-step explanation:
x = -b +/- square root(b^2 - 4ac) / 2a
ax^2 + bx + c = 0
these are both the quadratic formula but one is solved for the x and another for 0
a= 1
b= 6
c = -13
x= -6 +/- square root( 6^2 - 4(1)(13)) / 2(1)
x = -6 +/- sqrt( 36 + 52) / 2
x= -6 +/- sqrt (88) / 2
sqrt of 88 = 2 x sqrt (22)
divide 2 on each
x= -3 +/- sqrt (22)
Answer:
f = 65
Setup cost = 65
Step-by-step explanation:
Given the equation : 201.50=f+6.50(21)
Solving for f:
201.50 = f + 136.50
201.50 - 136.50 = f
f = 65
The equation above is written in the form a slope intercept function where,, 6.50 is the gradient and X equals the number of shirts, The total cost of printing is 201.50
f is the intercept and represents the initial fee or setup cost. Hence, the setup. Cost = 65
For number 12 the answer is 15.36
The aswer would be B because you have to divide a couple numbers to get 20in.
Answer:
