If line t has a slope of -1/4 what is the slope of any line perpendicular to line t

loris [4]

Answer: 4

Step-by-step explanation: Slopes that are perpendicular to each other are opposite reciprocals. So take the opposite of the sign, negative or positive. Then flip the numerator and the denominator. -1/4 goes to +1/4 goes to +4. Hope this helps!

Answer:

t=1p

Step-by-step explanation:

this problem is fairly easy. we will first do is set the equation to equal t also known as the total price. this is because you were trying to determine how much you will have to pay if she buys her food in bulk. you will then equal t to how much it will cost if the food is in bulk. to do this you will multiply 1 (this next she wants to buy weighs 1 kg) and multiply it by p (price per kilogram). Hope this helps!

On three examinations, you have grades of 85, 78, and 84. There is still a final examination, which counts as one grade In order

Greeley [361]

Answer:

It's not possible to earn an A in the course
I must have a 73 or MORE to earn a B in the course

Step-by-step explanation:

The average obtained at the end of the course will be:

$\frac{85+78+84+x}{4} = av$

Where x is the grade obtained in the final examination and av is the final average. To obtain an A, av has to be at least 90, av≥90, and to obtain an B, av has to be at least 80, av≥80

Is an A in the course possible?

So, if we get 100 on the final average:

x = 100,

av = (85+78+84+100)/4 = 86,75 and 86,75∠90.

Answer: No, the higher grade obtained would be 86,75.

What grade you must have in the final to earn a B in the course

To earn a B, av≥80:

$av= \frac{85+78+84+x}{4 \ }\geq 80\\ \frac{247+x}{4}\geq80 \\247+x\geq 80*4\\ x\geq 320-247\\ x\geq 73$

Answer: I must have a 73 or MORE to earn a B in the course
