Two lines have a slope of 3 and different y-intercepts how many solutions will this system have

Answer:

0 solutions / no solutions

Step-by-step explanation:

If two lines have the same slope but different y-intercepts, it means that they are parallel.

For example, we have two lines:

y = x

y = x + 1

Both lines have the same slope of 1, but different y - intercepts. Because each equation increases the x and y at the same right (slope) but started at different points, the two equations will never touch.

It's similar to two runner who run at the same pace. If one runner started 50 meters ahead, that runner will always be ahead 50 meters (y-intercept) because they both run at the same rate.

Answer:

You count the blocks and then put the amount of blocks before:)

(That sounds confusing but it sounds harder than it is)

The answer would be 3xy + 4x

Step-by-step explanation:

How many xy blocks are there? yea there's 3 so you do 3xy

you can't add xy and x blocks together because xy is a different unit than x (xy is x times y) so then you'd count the other x blocks seperately

(I'm sorry if I'm wrong on this lol)

nadezda [96]

Answer:

-8b - 32

Step-by-step explanation:

Distribute the 8 to each term in the parentheses:

8(-b) = -8b

8(-4) = -32

Add these two terms together:

-8b - 32 is the simplified expression

Maru [420]

Answer:

Step-by-step explanation:

Given that Poker is a card played with a standard 52 card playing deck. We draw one card at a time without replacement from the top of a shuffled standard poker deck and stop when we draw an ace.

There are 4 aces and 48 non aces.

For randomly drawing card for first card we have probability for drawing ace = 4/52 and non ace = 48/52

X = no of cards we have drawn

If X is the total no of cards drawn, then the event should have been

first x-1 cards non aces, and the last card ace.

Hence P(X)

= Drawing x-1 cards from 48 non aces * drawing one card from remaining 52-(x-1) cards

= $\frac{48C(x-1)}{52C(x-1)} *\frac{4}{53-x} \\$ , x=1,2,.....49

What is the slope of the passing through the points (4,6) and (-1, -2)

Likurg_2 [28]

$The\ slope:m=\dfrac{y_2-y_1}{x_2-x_1}\\------------------\\\\(4;\ 6)\to x_1=4\ and\ y_1=6\\(-1;-2)\to x_2=-1\ and\ y_2=-2\\\\subtitute\\\\m=\dfrac{-2-6}{-1-4}=\dfrac{-8}{-5}=\boxed{\frac{8}{5}}$

3q+3 because if the dimes is 3x as many as the quarter and plus 3 then you would multiply the quarters by 3 then add 3 and that would give you the number of dimes
