Answer:

Step-by-step explanation:

This would be easier to explain to you on a graph, but I shall do the best I can in text format.

You know what a complex plane looks like, right? Just like a number line but with a vertical number line added on at the point (0). This makes four quadrants, you know the drill.

So each quadrant holds all values from on of the four positive/negative combinations, (1, 1i), (1, -1i), (-1, -1i), and (-1, 1i), in that order.

So this means that all the pairs with both positive values are in quadrant I, all the pairs with a positive rational number but a negative irrational number are in II, etc.

If you have a graph, you can simply count along the number line to find the answer, so in this case, starting as always at (0, 0), move 6 units to the right and then eight units down, where you end up in the lower righthand quadrant, which is II.

Oof I know that was worded badly but I hope it's not totally useless to you <3

You're doing great with the test, Gem, I'm sure you'll do just fine <:

34. For the following exercises, given each set of information, find a linear equation satisfying the conditions, if possible.

skad [1K]

Answer:

The linear equation for the line which passes through the points given as (-1,4) and (5,2), is written in the point-slope form as $y=\frac{1}{3} x-\frac{13}{3}$ .

Step-by-step explanation:

A condition is given that a line passes through the points whose coordinates are (-1,4) and (5,2).

It is asked to find the linear equation which satisfies the given condition.

Step 1 of 3

Determine the slope of the line.

The points through which the line passes are given as (-1,4) and (5,2). Next, the formula for the slope is given as,

$m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}$

Substitute 2&4 for $y_{2}$ and $y_{1}$ respectively, and $5 \&-1$ for $x_{2}$ and $x_{1}$ respectively in the above formula. Then simplify to get the slope as follows,

$m=\frac{2-4}{5-(-1)}$\\ $m=\frac{-2}{6}$\\ $m=-\frac{1}{3}$$

Step 2 of 3

Write the linear equation in point-slope form.

A linear equation in point slope form is given as,

$y-y_{1}=m\left(x-x_{1}\right)$

Substitute $-\frac{1}{3}$ for m,-1 for $x_{1}$ , and 4 for $y_{1}$ in the above equation and simplify using the distributive property as follows,

$y-4=-\frac{1}{3}(x-(-1))$\\ $y-4=-\frac{1}{3}(x+1)$\\ $y-4=-\frac{1}{3} x-\frac{1}{3}$$

Step 3 of 3

Simplify the equation further.

Add 4 on each side of the equation $y-4=\frac{1}{3} x-\frac{1}{3}$ , and simplify as follows,

$y-4+4=\frac{1}{3} x-\frac{1}{3}+4$\\ $y=\frac{1}{3} x-\frac{1+12}{3}$\\ $y=\frac{1}{3} x-\frac{13}{3}$$

This is the required linear equation.

On a certain hot summer's day, 538 people used the public swimming pool. The daily prices are $1.75 for children and $2.25 for a

Artist 52 [7]

Answer:

The number of children was 170 and adults was 368.

Step-by-step explanation:

To clarify we'll call children by 'c' and adults by 'a'. The amount of people in the pool should be the sum of adults and children, so:

a + c = 538

The receipts for the adimission should total the amount of tickets from children and adults multiplied by the price of each ticket, so:

1.75*c + 2.25*a = 1125.5

We now have two equations and two variables. Using the first equation we can isolate the 'a' variable and use it on the second equation to find an answer. We then have:

a + c = 538

a = 538 - c

Using it on the second equation:

1.75*c + 2.25*(538-c) = 1125.5

1.75*c + 1210.5 - 2.25*c = 1125.5

1.75*c - 2.25*c = 1125.5 - 1210.5

-0.5*c = -85

c = -85/(-0.5) = 170

Using this value on the first equation:

a = 538 - 170 = 368

A pizza is cut into slices that are each 1/6 of the whole. John is going to eat 1/2 of the pizza. How many slices will John eat?

GarryVolchara [31]

Answer:

3 slices

Step-by-step explanation:

The pizza is cut into 6 slices

Since John wants to eat half of the pizza, you would need to divide 6 by 2 to get half

So the answer is 3 slices of pizza
