Atraeus is solving the quadratic equation by completing the square.7x^2 – 14x + 6 = 0 7x2 – 14x = –6 A(x^2 – 2x) = –6What is the value of A?

Answers

so we first minus 6 both sides
7x^2-14x=-6
then we have
A(x^2-2x)=-6
what is A?

hmm (this should be painfully obvous, but if not, here are steps)

7x^2-14x=-6
A(x^2-2x)=-6

7x^2-14x=-6=A(x^2-2x)
7x^2-14x=A(x^2-2x)
undistribute 7
7(x^2-2x)=A(x^2-2x)
divide both sides by (x^2-2x)
7=A

A=7

Kevin is an auto mechanic. He spends 2 hours when he replaces the shocks on a car and 2 hours when he replaces the brakes. He works no more than 42 hours a week. He routinely completes at least 4 shocks replacements and 6 break replacements a week. If he charges $450 for labor replacing shock and $200 in labor for replacing breaks, how many jobs of each type should he complete a week to maximize his income?Kevin should do ___ shock replacements and ___ brake replacements every week to maximize his weekly income.

Answers

Kevin has been working as an auto-mechanic. For maximizing weekly income Kevin should do 6 breaks replacement and 4 shock replacements. The time required for performing both the tasks has been equal. Since the time required has been the same, to increase the income, the task resulting in more income has been prioritized

Given :

The charges for shock replacement = $450,
The charge for breaks replacement = $200.

Since there have been more income with shock replacement, the brake replacement task has been prioritized.

The time Kevin works in a week has been 42 hours. Since each job takes 2 hours, the number of jobs he can perform has been 21 jobs.

The routine jobsof brake replacement performed by Kevin have been 6. Thus to increase his income, the rest jobs have been of shock replacement.

The number of shock replacement tasks performed by the Kevin =

= 21 - 6

= 15

The number of shock replacement jobs = 15.

Thus for increasing the income Kevin has to perform 6 brake replacement tasks and 15 shock replacement tasks.

Answer:

Kevin should do 15 shock replacements and 6 brake replacements every week to maximize his weekly income.

Step-by-step explanation:

Both jobs take the same amount of time to complete (2 hours), therefore, in order to maximize his income, Kevin should prioritize the job that gives him the greatest income, which is replacing shocks.

If each job takes 2 hours and he works at most 42 hours per week, Kevin can complete 21 jobs per week. He should aim to do as little break replacements as possible and as many shock replacements as possible to maximize income.

If he completes at least 6 break replacements, the remaining jobs should all be shock replacements:

$S=21-6\nS=15$

Kevin should do 15 shock replacements and 6 brake replacements every week to maximize his weekly income.

One half of a number is 3 more than one-sixth the same number. What is the number?

Answers

1/2 of a number(1/2 times x) is (=) 3 more than (3+) 1/6 the same number (1/6 times x)

1/2x=3+1/6x
x/2=3+x/6
subtract x/6 from both sdies
x/2-x/6=3
x/2-x/6
x/2 times 3/3=3x/6
3x/6-x/6=2x/6=x/3
x/3=3
multiply both sides by 3
x=9

9 is the number

$(x)/(2) = (x)/(6) + 3$

$3x= x+18$

$2x=18$

$x=9$

TRUE OR FALSE: −3 is a solution for the compound inequality b ≤ 4 and b > −1.

Answers

- 3 is a solution that satisfies both inequalities.So, the correct answer is True.The compound inequality consists of two separate inequalities connected by "and."

1.b ≤ 4:This means that "b" is less than or equal to 4.

2.b > −1:This means that "b" is greater than -1.

If we consider a number line, the values that satisfy both conditions are those that are greater than -1 but also less than or equal to 4. The value -3 falls within this range. It is greater than -1 and also less than 4.

Therefore, -3 is a solution that satisfies both inequalities, making the statement true.

A foreman for an injection-molding firm admits that on 55% of his shifts, he forgets to shut off the injection machine on his line. This causes the machine to overheat, increasing the probability that a defective molding will be produced during the early morning run from 3% to 15%. The plant manager randomly selects a molding from the early morning run and discovers it is defective. What is the probability that the foreman forgot to shut off the machine the previous night?
