Answer:
D
Step-by-step explanation:
X = larger number
x-1 = smaller number
x*(x-1)=5+3x
x^2-4x-5=0 use the formula
x=5
x-1=4
the 2 numbers are 5&4 or -1,-2
Answer:
C. Nonlinear
General Formulas and Concepts:
<u>Algebra I</u>
- Linear - Proportional relationship y = mx + b
- Nonlinear - Any graph that has a degree <em>x</em> higher than 1
Step-by-step explanation:
<u>Step 1: Define</u>
y = 6x³ - 13
<u>Step 2: Identify</u>
We see a cubic function. Quadratics, Cubics, Quartics, etc. are all nonlinear equations.
First we need to assume that the sum of the angles is also 180°. if one is less than 90°, the other will be more. we can do this because in a plane 4-sided polygon the sum of the inner angles will always be 360°, and we already know the two angles on the right side
so we can say that:
3x + 20 + x = 180
Since we got only one variable in this equation, we can already solve for x.
4x + 20 = 180
4x = 160
x = 40
the lower left angle is just 40°
the upper left is three times that plus 20, so it's 160°
hope this helps you to get the method
