3 consecutive odd numbers....x, x + 2, x + 4

P = a + b + c
87 = x + x + 2 + x + 4
87 = 3x + 6
87 - 6 = 3x
81 = 3x
27 = x

x + 2 = 27 + 2 = 29
x + 4 = 27 + 4 = 31

ur 3 sides are 27,29,31...with 31 being the longest

X + (x+2) + (x+4) = 87

3x = 81 -> x = 27

So the longest will be 27 + 4 = 31

Janie is analyzing a quadratic function f(x) and a linear function g(x). Will they intersect?
UkoKoshka [18]

Answer:

Option (D) is correct.

No, They will not intersect.

Step-by-step explanation:

Given Points for g(x), (1,2) , (2,4) and (3,6)

Since g is a linear function then it must be in form of  g(x) = mx +c where, c is constant and m is slope.

We first calculate the slope using,

m=\frac{y_2-y_1}{x_2-x_1}

Here, consider x_1=1 , x_2=2 , y_1=2, y_2=4

Substitute above, we get slope as,

m=\frac{4-2}{2-1}=2

Thus, equation becomes g(x) = 2x + c  ...(1)

For c plug the values  in (1),

(1,2) ⇒ 2= 2 + c ⇒  c = 0

Thus, Equation of G(x) is 2x.

When we plot it it do not intersect f(x).

Thus, Option (D) is correct.

No, They will not intersect.

Look at number 17. What did I do wrong?
Gnesinka [82]
When you are checking your answers, your formula should read out as 9(2.222) - 8 = 12, which is simply filing in the x value that you calculated (it comes out to 11.998 which is correct). You wrote it out as 9(2.22) - 8 = -6, which is why your checking process was incorrect
