Write the equation in slope-intercept form.

y=12+(x-1)(-4)

Answers

Answer 1
Answer: To get slope-intercept form we have to multiply x-1 by -4 and simplify it then
y=12+(x-1)(-4)
y=12+x*(-4)-1*(-4)
y=12-4x+4
y=-4x+16 - its the result

Giselle works as a carpenter and as a blacksmith. She earns $20\$20 $20 dollar sign, 20 per hour as a carpenter and $25\$25 $25 dollar sign, 25 per hour as a blacksmith. Last week, Giselle worked both jobs for a total of 3030 30 30 hours, and earned a total of $690\$690 $690 dollar sign, 690 . How long did Giselle work as a carpenter last week, and how long did she work as a blacksmith? Giselle worked as a carpenter for hours and as a blacksmith for hours last week.

Answers

c = # of carpenter hrs , b = # of blacksmith hrs

c + b = 30...c = 30 - b
20c + 25b = 690

20(30 - b) + 25b = 690
600 - 20b + 25b = 690
-20b + 25b = 690 - 600
5b = 90
b = 90/5
b = 18 <== hrs worked as blacksmith

c + b = 30
c + 18 = 30
c = 30 - 18
c = 12 <== hrs worked as carpenter

Answer:

Carpenter: 12 hours and Blacksmith: 18 hour

PLEASE HELP!!!What is Linear Programming ? When was it developed and Why? How was this beneficial to the time? You should write at least two paragraphs. ANYTHING LESS WILL GET A LOWER GRADE ​

Answers

Linear Programming is a method to successfully achieve the most best outcome in a mathematical model with the requirements that are represented by linear relationships. A special case of mathematical programming.
Linear Programming was developed in the 1940’s which was made to obtain the most optimal solution for a problem with given constraints. This was beneficial to the time because it was a mathematical technique that determined the best ways to use available resources. Which some used to help make the decisions about money, time, materials, and machinery.

Solve for e:(-7)=e/3+14? show your work

Answers

-7 = (e)/(3) + 14
take 14 to the other side
-7 -(14) = (e)/(3)
-21 = (e)/(3)
Multiply by 3 on either sides to isolate e and to find a value

-21 × 3 = (e)/(3) × 3
3 and 3 cancels out

-63 = e

Alex is saving money to buy a new smartphone. he has already saved 250$ he plans on saving 30$ a week. how many weeks will it take for alex to have enough money to buy the smartphone which cost 550$

Answers

Answer: To find out how many weeks it will take for Alex to have enough money to buy the smartphone, we need to use the following formula:

weeks=rategoal−saved​

where:

goal is the amount of money he needs to buy the smartphone, which is 550$

saved is the amount of money he has already saved, which is 250$

rate is the amount of money he saves per week, which is 30$

Plugging in these values, we get:

weeks=550−250​/30

Simplifying, we get:

weeks=300​/30

Dividing, we get:

weeks=10

Therefore, it will take Alex 10 weeks to have enough money to buy the smartphone. I hope this helps.

Answer:

Not including the 250$ he already saved, it would take Alex 10 weeks to have to 550$ he needs to buy the smartphone.

Step-by-step explanation:

Subtract 250 from 550 and then divide the difference by 30, since Alex plans on saving 30$ per week. The result is 10, which is your answer.

Hope this helps you!
