I’m sorry but need help
arsen [322]

These are pretty easy once you get the concept.

think of <em>random letter</em> (x) as the term y, so in the case of p(x)=-3+4x, its just asking what is y when x equals all those values.

so p(-2) = -3 + 4(-2), since its asking to plug in -2 for x, which equals -11

p(0) = -3 + 4(0)

= -3

p(5) = -3 + 4(5)

= 17

Marco puts his coins into stacks. Each stack has 10 coins.
Harrizon [31]

Answer:

Marco has $57.50 in total.

Step-by-step explanation:

17 x 10 = 170 quarters

170 x 0.25 = $42.50

11 x 10 = 110 dimes

110 x 0.10 = $11.00

8 x 10 = 80 nickels

80 x 0.05 = $4.00

Pleasee helppp insert two arithnetic means between -5 and 1
Salsk061 [2.6K]

Answer:

a₂ = -3

a₃  = -1

Step-by-step explanation:

We have to  insert two arithmetic means between -5 and 1

Let a₁ and b₂ be the two arithmetic means between -5 and 1

-5, a₂, a₃, 1

Here,

  • a₄ = 1
  • a₁ = -5

We know that the nth term of an Arithmetic sequence

aₙ = a₁ + (n-1)d

a₄ = -5 + (4-1)d

1 = -5 + 3d    

1  + 5 = 3d

3d = 6

Dividing both sides by 2

d = 2

Also

a₂ = a₁ + (2-1)d

a₂ = -5 + d

a₂ = -5 + 2          ∵ d = 2

a₂  = -3

a₃ = a₁ + (3-1)d

a₃  = -5 + 2d

a₃  = -5 + 2(2)   ∵ d = 2

a₃  = -5 + 4

a₃  = -1

Thus,

a₂ = -3

a₃  = -1

Thus, the sequence becomes:

-5, -3, -3, 1
