Answer:

y=-2

neonofarm [45]

Answer:
0, 3, 6, 9, 12 .....

Explanation:
An arithmetic sequence is defined as a sequence of numbers that increases or decreases by a constant value. 
The values are increasing when the same number is added or subtracted onto the number.
The rest of the choices do not have a constant number being added or subtracted they are either:
multiplied: option (D),
divided: option (C),
a list of perfect squares: option (B).

The answer (A) had the constant of 3 added to each term increasing forever.

The New Orleans Saints scored 7 fewer points than twice the points scored by the Pittsburgh Steelers. The two teams together sco

zalisa [80]

Answer:

(m) + 2 (m) - 7 = 32 is the needed expression.

Points scored by Pittsburgh Steelers = 13

Points scored by New Orleans Saints = 19

Step-by-step explanation:

Let us assume the points scored by Pittsburgh Steelers = m

So, the Points scored by New Orleans Saints

= 2 (Points scored by Pittsburgh Steelers ) - 7

= 2 (m) - 7

Also,the total points scored by both teams = 32

So the points scored by( New Orleans Saints + Pittsburgh Steelers) = 32

⇒ (m) + 2 (m) - 7 = 32

or, 3 m = 32 + 7 = 39

⇒ m = 39/ 3 = 13, or m = 13

So, the points cored by Pittsburgh Steelers = m = 13

and the points scored by New Orleans Saints = 2m - 17

= 2(13) - 7 = 19

Can someone help please I don’t have much time???

Monica [59]

Answer:

1) x<2.5 2) x<2.5 (both are smaller numbers than 2.5)

Step-by-step explanation:

I'm sure there is a easier way to figure this question out but how I did is by simply imputing numbers smaller or bigger into where the x is. For example, I imputed 3 into -4x+5>-5. So, -4(3)+5>5, = -7>5, this is false, so x must be smaller than 2.5 in order for this to be true.
