The table represents the function f (x) = 2 x + 1.
Salsk061 [2.6K]

Answer:

C

Step-by-step explanation:

In the table, we are given the points [ (-3, -5), (2, y), (5, 11), (8, 17) ]

We are given the equation [ f(x) = 2x + 1 ] where 2 = slope and 1 = y intercept.

We need to find the value of "y".

y2-y1/x2-x1

y-(-5)/2-(-3) = 2

y+5/5 = 2

y = 5

Best of Luck!

If a quantity increases by 25% and then decreases by 25%, will that result be the original quantity? Explain.
alexandr1967 [171]
<span>If a quantity increases by 25% and then decreases by 25%, will that result be the original quantity? Explain.
Let’s try to be able to know the answer:
=> Let’s have 10 as the value
Increase by 25%
=> 10 + 25%
=> 10 * .25 =  2.5
=> 10 + 2.5 = 12.5 the new value
Now, decrease this by 25%
=> 12.5 – 25%
=> 12.5 * .25 = 3.125
=> 12.5 – 3.125 = 9.375 or 9.4
Thus, the given statement is false.

What is the answer to thiss
lana [24]

Hi Student!

This question is fairly simple because it gives us an equation and they also give us a value for the variable that is within the equation and they tell us evaluate the expression.  So let's plug in the values and solve.

<u>Plug in the values</u>

  • m^2 + 5
  • (9)^2 + 5

<u>Factor out the exponent</u>

  • (9*9) + 5
  • 81 + 5

<u>Combine</u>

  • 86

Therefore, the final answer that we would get when substituting m with 9 in the given equation is that we get 86.
