What is the slope of the line 3x – 9y = 4?

Mathematics
1 answer:
siniylev [52]3 years ago
3 0

Answer:

Slope = \frac{1}{3}

Step-by-step explanation:

Write the equation in y =mx + c form

3x - 9y = 4

    -9y = -3x + 4

       y = \frac{-3x}{-9}+ \frac{4}{-9}\\\\y =\frac{x}{3} - \frac{4}{9}\\m = \frac{1}{3}

Which expression is equivalent to (7 – 3k) – (4 – 5k) – (6 – 2k)?
gladu [14]

Answer:

The right response is "3(k-1)". A further solution is given below.

Step-by-step explanation:

The given expression is:

⇒ (7 -3k) - (4 - 5k) - (6 - 2k)

On solving the above expression, we get

⇒ 7-3k-4+5k-6+2k

⇒ 7-3k-10+7k

⇒ 3k-3

On taking "3" as common, we get

⇒ 3(k -1 )

A company manufactures and sells shirts. The daily profit the company makes
Rom4ik [11]

Answer:

f(-5) = -150

Meaning: If the company sells -5 shirts, they would make a profit of -150 dollars. This interpretation of loss in the context of the problem

f(7) = -30

Meaning: If the company sells 7 shirts, they would make a profit of -30 dollars. This interpretation of loss in the context of the problem

f(10.5) = 5

Meaning: If the company sells 10.5 shirts, they would make a profit of 5 dollars. This interpretation of profit in the context of the problem

Step-by-step explanation:

Given

f(x) = 10x - 100

Required

Fill in the gap

f(-5) = 10 * -5 -100

f(-5) = -50 -100

f(-5) = -150

f(7) = 10 * 7 - 100

f(7) = 70 - 100

f(7) = -30

f(10.5) = 10 * 10.5 - 100

f(10.5) = 105 - 100

f(10.5) = 5

Chia is planning a sailing party for her friends the boat rental is $150 plus an additional $15 per person see it has saved up $
storchak [24]
150 + 15x = 400
(-150) 150 + 15x = 400 (-150)
15x = 250
(/15) 15x = 250 (/15)
x = 16.67
So Chia can invite 16 people

17.5 how to make this into a fraction
BARSIC [14]
Take the .5 of the 17.5 and convert it to a fractin.
we know .5 is equal to 50% or 1/2 

now we have a mixed number  17 \frac{1}{2}

in order to convert it into an improper fraction you need to multiply the whole number by the denominator and then add the numerator all while keeping the denominator constant. 

W \frac{N}{D} =  \frac{(W*D)+N}{D}

so 17 \frac{1}{2}= \frac{(17*2)+1}{2}= \frac{35}{2}
