<span>Perpendicular lines' slopes are reciprocals of one another. So we know the perpendicular line will have a slope of 1/2. Then we can use our points to find the rest. 8=1/2(1)+b 8=0.5+b 7.5=b y=2x+b</span>

After adding everything together you should get y=-2x+10

Hi,

The two numbers should be 12 and 30. 12=2x2x3 while 30=2x3x5.

Their HCF is 2x3=6 and their LCM is 2x3x2x5. Because of their HFC, we know that they are both multiple of 6. Also, the question says they both are GREATER than 6, so they can’t be 6 but are 6 times “something”. Thanks to the LCM, we know that “something” is equal to 2 for the first number and to 5 for the second one, the numbers hence being 12 and 30.

I hope this helps. If I was not clear enough or if you’d like further explanation please let me know. Also, English is not my first language, so I’m sorry for any mistakes.

What is a real world word problem for 57.5=p(250)
sladkih [1.3K]
If p(x) is a function, then a real-world example might be

The amount of fish food, in grams required for the giant koi fish in the pond can be represented by the function p(f)=\frac{f}{50} +7.5. If there are 50 fish, how many grams of fish food will you need?

p(250)=\frac{250}{50} +7.5
p(250)=50 +7.5
p(250) = 57.5

What is the remainder when f(x) = x^2 + 14x − 8 is divided by (x − 5)? 103 88 87 72
il63 [147K]

Answer:

<h2>The answer is 87</h2>

Step-by-step explanation:

f(x) = x² + 14x - 5

To find the reminder when f(x) is divided by x - 5 , substitute the value of x into the above formula

That's

x - 5 = 0

x = 5

So we have

f(5) = 5² + 14(5) - 8

f(5) = 25 + 70 - 8

f(5) = 95 - 8

We have the final answer as

<h3>87</h3>

Hope this helps you
