We can rearrange 3x+y=9 to look more conventional by subtracting 3x from both sides and making it y= -3x+9.

Now we want to find a line that is parallel to this and goes through the point (0,-4). We know that -3 is the slope. With this in mind, if we want the other line to be parallel then it must have the same slope so that they never intersect. This gives us one of the numbers we need for the second line.

This means our second equation is looking like; y= -3x+b. This means we need to find b (the y-intercept) but we are also given a point it must go through and this is (0,-4). We simply plug this in into our new equation we need to solve and we get ; -4 = -3(0) + b . "since 0 is the x and -4 is the y" . From this we get that b= -4. This means the equation of a line parallel is:

y = -3x-4

Mrs. Anderson has 128 pencils left over at the end of the school year. She decides to keep half of them for the next year and di

grandymaker [24]

First we need to figure out what half of 128 is

128 ÷ 2 = 64

Now, we need to divide 64 by the amount of students she has (16)

64 ÷ 16 = 4

Therefore, each student will get 4 pencils meaning the answer is D

Hope this helps

Hey I’m struggling with number 13 so please show your work. Thx

Answer:

$\frac{5}{12}$

Step-by-step explanation:

Because $\frac{3}{5}$ is being multiplied by S, we can divide $\frac{3}{5}$ from both sides of the equation. This will give us:

$\frac{1}{4}$ ÷ $\frac{3}{5}$

But, that looks a bit hectic. Instead of dividing, you can multiply by the reciprocal (which is essentially how to divide fractions). So, instead of $\frac{1}{4}$ ÷ $\frac{3}{5}$ , you get:

$\frac{1}{4}$ × $\frac{5}{3}$

When multiplying fractions, remember you can just multiply straight across-- numerator x numerator, then denominator x denominator.

By doing that, you get the fraction $\frac{5}{12}$

$\frac{5}{12}$ cannot be simplified any more, so S= $\frac{5}{12}$ is your answer :)

I hope this helps

Answer: C = 150$

Explanation:

C = chair
T = table

C = 10% of T
C = 10/100 x T
C = 1/10 x T

And
T + 4C = 2100$
T + 4(1/10 x T) = 2100$
T + (4T/10) = 2100$
T + 2T/5 = 2100$
5T + 2T = 10500$
7T = 10500$
T = 1500$

But C = (1/10)T
=> C = 1/10 x 1500$
C = 150$

Answer:

50%

Step-by-step explanation:

The percentage of people between 20 and 37 years old.

From the attached box plot :

Number of people aged up to 20 marks the lower quartile of the distribution = lower 25%

Number of people aged up to 37 marks the upper quartile of the distribution = lower 75%

Hence, percentage number of people aged between 20 and 37 equals

Q3 - Q1 = 75% - 25% = 50%
