Answer:

The graph shows the proportional relationship between total spent and number of months

A proportional relationship has the following characteristics

In a proportional relationship, the ratio of the 'x' and 'y' values is constant for all data pairs

The rate of change between the two quantities in a proportional relationship is constant

The graph of a directly proportional relationship passes through the origin

Therefore, the significance of the given points are;

1. The point (1, 5) is the first point that indicates the proportional relationship between the 'x' and 'y' values and from which the the constant of proportionality, k = y/x can be found as follows;

When x = 1 month, and y = $ 5, for the proportional relationship, we have;

k = y/x = $ 5/(1 month) = 5 $/month

2. The point (0, 0) is the starting point of the relationship and indicates that the graph of the 'x', and 'y', values passes through the origin and the relationship between the ;x;, and ;y;, values is a directly proportional relationship

3. The point (4, 20) which is the limiting point or the point with the highest 'y' value gives;

1) The total payment after 5 months

2) it can be used to draw the graph of the straight line relationship

3) Provides verification of the constant of proportionality

What is the solution set for this linear-quadratic system of equations?

Y - x - 3 = 0
y = x + 3

y = x^2 - x - 12
x + 3 = x^2 - x - 12
x^2 - x - 12 - x - 3 = 0
x^2 - 2x - 15 = 0
(x - 5)(x + 3) = 0

x - 5 = 0 y = x + 3
x = 5 y = 5 + 3
y = 8

x + 3 = 0 y = x + 3
x = -3 y = -3 + 3
y = 0

so ur solutions are : (5,8) and (-3,0)

Many poker games start with each player being dealt five cards, called the player's "hand". Remember, there are 52 cards in a st

jek_recluse [69]

Answer:

The number of different possible poker hands is found by counting the number of ways that 5 cards can be selected from 52 cards, where the order is not important. It is a combination, so we use c n r

Step-by-step explanation:

The possible number of the poker hands is probably . C 52 5= 52!/5!x47!= 2598960

Please help! THE QUESTION IS IN THE PIC!

Kruka [31]

Answer:

-11 x + 19 thus c.) is your answer

Step-by-step explanation:

Simplify the following:

-5 + 4 (6 - 2 x) - 3 x

4 (6 - 2 x) = 24 - 8 x:

-3 x + 24 - 8 x - 5

Add like terms. 24 - 5 = 19:

-3 x - 8 x + 19

-8 x - 3 x = -11 x:

Answer: -11 x + 19

HELP ME PLEASE I NEED HELP

Olin [163]

Step-by-step explanation:

You should prolly subtract 2 from both sides first.

So you get, -|2/5x + 3| > -1 2/5

Add three to both sides
-|2/5x| = -1 2/5
Do -1 and 2/5 divided by 2/5 to get -3.5, x > -3.5

One of the answers is x > -3.5 but you need to switch the sign to less than and make the other side the opposite.

$-( \frac{2}{5}x + 3 ) < 1 \frac{2}{5}$

You see that, switched the sign and made whats on the right side opposite. So now solve for x again but with this new equation. Also, the parentheses are absolute value signs

Subtract 3 from both sides

-|2/5x| < -1 and 3/5

Divide 2/5 from each side to get x < -4

I hope I'm correct, my bad if I'm wrong
