determine the equation of the line that has the given slope and travels through thegiven point (3,-4) and m=2
iren2701 [21]
Y = mx + c
-4 = 2(3) + c
-4 = 6 + c
-10 = c

y = mx + c
y = 2x - 10
Hence, the equation is y=2x-10.

Emma was about to finish grocery shopping when she noticed that cans of soup were on sale. Her total bill for groceries would be
Alinara [238K]

Answer:

3rd option: B(C)= 1.79C +86.03

Step-by-step explanation:

Total bill

= cost of cans(number of cans) +cost of other groceries

Let the cost of other groceries be G, and the cost of cans be X.

Given that number of cans= C,

Total bill= XC +G

If 2 cans were purchased,

2X+G= 89.61 -----(1)

If 5 cans were purchased,

5X +G= 94.98 -----(2)

(2) -(1):

(5X +G) -(2X +G)= 94.98 -89.61

5X +G -2x -G= 5.37

3X= 5.37

X= 5.37 ÷3 <em>(</em><em>÷</em><em>3</em><em> </em><em>on</em><em> </em><em>both</em><em> </em><em>sides</em><em>)</em>

X= 1.79

Subst. X= 1.79 into (1):

2(1.79) +G= 89.61

3.58 +G= 89.61

G= 89.61 -3.58 <em>(</em><em>-3.58</em><em> </em><em>on</em><em> </em><em>both</em><em> </em><em>sides</em><em>)</em>

G= 86.03 <em>(</em><em>simplify</em><em>)</em>

Total bill

= XC +G

= 1.79C +86.03

Thus, the function is B(C)= 1.79C +86.03.

Three cards are randomly selected from a standard 52-card deck, one at a time, with each card re- placed in the deck before the
hammer [34]

Answer:

\frac{1}{4}

Step-by-step explanation:

Three cards are randomly selected from a standard 52-card deck.

Number of heart cards in a deck = 13

Each card replaced in the deck before the next one is picked.

Probability of first card is heart = P_{1}=\frac{13}{52}

After replacement, the probability of second card is heart = P_{2}=\frac{13}{52}

after replacement, the probability of third card is heart =  P_{3}=\frac{13}{52}

P =  \frac{13}{52} ×  \frac{13}{52} ×  \frac{13}{52}

  =  \frac{39}{156}

  =  \frac{1}{4}

The probability of all three cards are hearts is  \frac{1}{4}
