Answer:

Explanation:
[ Divide Both Sides By 12y ]
12xy / 12y = 5z / 12y
- PNW
Start by identifying your x1, x2, y1, and y2 values
x1: -2
x2: 9
y1: -20
y2: 79
The general form for writing a point slope equation is y-y1 = m(x-x1)
M is your slope.
To find the slope, plug the values you just identified into the equation y2-y1/x2-x1
This leaves you with 79+20/9+2
Which equals 9, so your slope (m) equals nine.
you can now plug everything into the general form which gives you:
y+20 = 9(x+2)
Answer:
0.001145
Step-by-step explanation:
Given that you are certain to get 3 jacks when selecting 51 cards from a shuffled deck.
When we draw 3 cards from 51 cards, we keep one card aside
The card can be either Jack or non Jack
Prob (the left over card to be Jack) = P(A) = 
Prob (the left over card to be non jack ) = P(B) = 
A and B are mutually exclusive and exhaustive
Let drawing 3 Jacks be the event C
P(C) = P(AC)+P(BC)

P(BC) = P(B)*P(C/B)\\
= \frac{28}{52} (4/51C3)\\
=1.034(10^{-4}
Adding we get
P(C)
= 
The complete question in the attached figure
A) How much material does he need to cover one rectangular side of the tent?
to cover the rectangular side ABCD, calculate the area
Area=CD*AC=9*6=54 ft²
the answer part A is 54 ft²
B) <span>If David’s dad wanted to re-cover the whole tent, how much material would he need?
the area total=2*[Area ABCD]+2*[Area ACE]
</span>Area ABCD=9*6=54 ft²
Area ACE=(1/2)*7*6=21 ft²
the area total=2*[54]+2*[21]=150 ft²
the answer part B is 150 ft²
C) <span>If David found a roll of tent material in the garage that was 65 ft2, would he have enough material to cover the entire tent? Explain your reasoning.
to cover the entire tent is required 150 </span>ft²
150 ft²> 65 ft²------> David not have enough material to cover the entire tent
<span>
the answer part C is
</span>David not have enough material to cover the entire tent
Answer: -2 and 4
Step-by-step: You see the horizontal line? now look at the the numbers -2 and 4 on that line. Notice how the line passes through them? those are your x-intercepts.
