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 wo
nata0808 [166]

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\\S=15

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

How can we get Equation B from Equation A? A. 5 = -2 (x - 1) B. 5 = -2x + 2 How can we get Equation B from Equation A?
lesya [120]

Answer:

Please check the explanation.

Step-by-step explanation:

<u>Determining equation B from Equation A</u>

Given the equation A

5\:=\:-2\:\left(x\:-\:1\right)

Apply distributive law a\left(b-c\right)=ab-ac

5= -2x+2    which is equation B

Hence, equation B can be obtained by implementing the distributive law operation on equation A.

<u>Determining equation A from Equation B</u>

Given the equation B

5 = -2x + 2

Factor out common term -2 on the right-hand side of the equation

5=-2\left(x-1\right)  which is the equation A

Hence, equation A can be obtained by factoring out the common term -2 on the right-hand side of equation B.

Does anyone know what 'intercepts' and 'gradient' is in Algebra. Doing revision for Math Exam and can't find it anywhere in note
lorasvet [3.4K]

gradient is difference in y / difference in x

(easiest way is to draw a right angle triangle and the gradient is the hypotenuse)


x intercept is where the graph goes through the x axis (left to right)

y intercept is where the graph goes through the y axis (up and down)


hope that helps you get it

Write the equation of the line that passes through the point (2, 6) and is perpendicular to the line x = 4
worty [1.4K]

Answer:

The perpendicular line would be y = 6

Step-by-step explanation:

In order to get this, we must first recognize that the equation given is a vertical line. If our new line is to be perpendicular to it, it must be a horizontal line. All horizontal lines are written as y = (a number). Since we have a point it goes through, we can get that value in the ordered pair. The ordered pair has a y value of 6, which means the equation would be y = 6
