Answer:

Step-by-step explanation:

First problem:

blank 2) on the left: PR = PQ + QR

blank 3) on the right: Replace PR in statement 1) with what we just completed in statement 2. Therefore:

2PQ = PR

2PQ = PQ + QR

blank 4) on the right: Subtract PQ from both sides, therefore

2PQ = PQ + QR

2PQ - PQ = PQ + QR - PQ

PQ = QR

You are dealt one card from 52 card deck. Find the possibility that you are dealt a heart or a picture card

PIT_PIT [208]

Answer:

Step-by-step explanation:

Since we have 13 heart card then

p(heart) = 13/52

Since we have 12 picture card then

p(picture) = 12/52

Since we have 3 heart and picture (at the same time) card then

p(heart∩picture) = 3/52

finally,

the possibility that you are dealt a heart or a picture card = p(heart or picture)

p(heart or picture) = 13/52 + 12/52 - 3/52 = 22/52

Answer:

It should be the first one

Step-by-step explanation:

since positive ten would represent going further up and negative ten going further down, the diver would be within ten feet of her current position

write an equation for the line that passes through the given point and has the given slope m (4,-5);m= -1/4

EastWind [94]

-------------------------------------------------------------------------------------------------------------

Answer: $\textsf{y = -1/4x - 4}$

-------------------------------------------------------------------------------------------------------------

Given: $\textsf{Slope = -1/4, Point through = (4, -5)}$

Find: $\textsf{Equation for the line that passes through the given point}$

Solution: In order to get the equation, we need to first use the point-slope form to help us sort out our information and then we solve for y.

<u>Plug in the values</u>

$\textsf{y - y}_1\textsf{ = m(x - x}_1\textsf{)}$

$\textsf{y - (-5) = -1/4(x - 4)}$

<u>Simplify and solve for y</u>

$\textsf{y + 5 = -1/4(x - 4)}$

$\textsf{y + 5 = -1/4x + 1}$

$\textsf{y + 5 - 5 = -1/4x + 1 - 5}$

$\textsf{y = -1/4x - 4}$

Therefore, the final answer would be that the equation that has a slope of -1/4 and passes through (4, -5) is y = -1/4x - 4.
