Answer:

f(-3) =16

Step-by-step explanation:

f(x) = -5x + 1

f(-3) means let x=-3

Substituting x=-3 into the equation

f(-3) = -5 (-3) +1

Multiplying -5 and -3

f(-3) = 15+1

f(-3) =16

m_a_m_a [10]

Answer:

5 rings

Step-by-step explanation:

sam can only buy 5 rings because each ring cost $16 and after he bought the jeans which cost $45 it left him with only $95. so if you times 16 and 5 it gives you 80 and if you times 16 and 6 it gives you 96 but sam only had $95 left so he could only buy 5 which cost him $80. that left him with an extra $15.

What is the perimeter of △ABC?<br> Round each step to the nearest tenth.
trapecia [35]
Required Perimeter = AB + BC + CA
AB = sqrt((5 - (-1))^2 + (-1 - 1)^2) = sqrt(6^2 + (-2)^2) = sqrt(36 + 4) = sqrt(40) = 6.3
BC = sqrt((-1 - 0)^2 + (1 - (-3))^2) = sqrt((-1)^2 + 4^2) = sqrt(1 + 16) = sqrt(17) = 4.1
CA = sqrt((0 - 5)^2 + (-3 - (-1))^2) = sqrt((-5)^2 + (-2)^2) = sqrt(25 + 4) = sqrt(29) = 5.4

Perimeter = 6.3 + 4.1 + 5.4 = 15.8 units

you pick a card at random from an ordinary deck of 52 cards. If the card is an ace, you get 9 points; if not, you lose a point​
nexus9112 [7]

Answer: a = 9, b = 48, c = -1

<u>Step-by-step explanation:</u>

"a" represents the points you receive if an Ace is picked.  It is given that you get 9 points ----> a = 9

"b" represents the number of cards that are Not an Ace.  4 cards in the deck are Aces so 52 - 4 = 48 cards are Not an Ace -----> b = 48

"c" represents the points you receive if Not an Ace is picked.  It is given that you lose 1 point ----> c = -1
