Total angle degree for a parallelogram is 360 degrees
The angles added up is 6x
So 6x=360
X=60

Given: f(x) = 3x-7, g(x)=2x2 -3x+1, h(x)=4x+1, k(x) =-x2+3 Find: k(x) +g(x)​
Afina-wow [57]

Answer:

k(x) + g(x) = x² - 3x + 4

General Formulas and Concepts:

<u>Alg I</u>

  • Combining like terms

Step-by-step explanation:

<u>Step 1: Define</u>

f(x) = 3x - 7

g(x) = 2x² - 3x + 1

h(x) = 4x + 1

k(x) = -x² + 3

<u>Step 2: Find k(x) + g(x)</u>

  1. Substitute:                              k(x) + g(x) = -x² + 3 + 2x² - 3x + 1
  2. Combine like terms (x²):        k(x) + g(x) = x² + 3 - 3x + 1
  3. Combine like terms (Z):         k(x) + g(x) = x² - 3x + 4

Can anyone help me? i dont get it
algol13

Because t is the number of weeks, replace t with 6 in the equation and solve for s.

s = -0.25(6) +4

s = -1.5 +4

s = 2.5

Now replace t with multiples of 6, use 12 and 18:

s =-.25(12) +4 = 1

s-0.25(18) +4 = -0.5

now fins the difference between the time frames:

2.5 - 1 = 1.5

1 - 0.5 = 1.5


The ice melts 1.5 meters every 6 weeks.

X = y 2 - 1
pochemuha
Your answer would be option B. 2y² - y - 6 = 0. This is because if you were to substitute x = y² - 1 into the equation 2x - y = 4, you would get 2(y² - 1) - y = 4, which expands into 2y² - 2 - y = 4, and then simplifies to 2y² - y - 6 = 0.
I hope this helps!
