Plug in x = 7. Then use the order of operations (PEMDAS) to simplify
y = 11 - 5*x
y = 11 - 5*7 .... x has been replaced with 7 (since x = 7 is given)
y = 11 - 35
y = -24
Discriminant. Discriminant, in mathematics, a parameter of an object or system calculated as an aid to its classification or solution. In the case of a quadratic equation ax2 + bx + c = 0, the discriminant is b2 − 4ac; for a cubic equation x3 + ax2 + bx + c = 0, the discriminant is a2b2 + 18abc − 4b3 − 4a3c − 27c2.
Answer:
31.9 Hours OR 4.5 Hours (Read Explanation)
Step-by-step explanation:
40 x 7.50 ( To find the amount that he worked in non-overtime) = 300
300 - 339.98 = 39.98 (Money made on overtime)
39.98 / 1.25 = 31.984 (Hours worked on overtime)
If he is getting payed $1.25 extra per hour (That was not super clear) it would instead be:
39.98 / (1.25 + 7.50) (Money made on overtime divided by hourly rate)
39.98 / 8.75 = 4.5 Hours worked overtime
This answer makes more sense, but since it isn't super clear I'll give you both.
