HELP ASAP PLZ &THANK YOU :)

The standard form:

Ax+By=C

The slope-intercept form:

y=mx+b

m - slope

m=\dfrac{y_2-y_1}{x_2-x_1}

b - y-intercept (0, b).

We have the point (0, 43) → b= 43.

Next point (2, 55). Substitute to the slope formula:

m=\dfrac{55-43}{2-0}=\dfrac{12}{2}=6

Therefore we have:

y=6x+43      <em>subtract 6x from both sides</em>

\boxed{-6x+y=43}

Reuben made 4 identical necklaces, each having beads and a pendant. The total cost of the beads and pendants for all 4 necklaces
zysi [14]

Answer:

$3.90

Step-by-step explanation:

The total cost was $24.40.

We know the cost for beads for each necklace is also $2.20, multiply this by four to find the cost of the beads for all the necklaces.

$2.20 × 4 = $8.80

Now we will subtract this from the total price.

$24.40 - $8.80 = $15.60

$15.60 Is the remaining cost for the pendants of all four necklaces. We will now divide this by four to find the price of a single pendant.

$15.60 ÷ 4 = $3.90

<u>This means the cost of each pendant is $3.90</u>

You reach into the jar and randomly select a jelly bean, then select another without putting the first jelly bean back. What is the probability that you draw two red jelly beans? This is Dependent because you didnt put the other jelly bean in thus changing the total nmber of jelly beans.
