Answer:
C, Linear
General Formulas and Concepts:
<u>Algebra I
</u>
- Linear - Proportional relationship y = mx + b
- Nonlinear - Any graph that has a degree x higher than 1
Step-by-step explanation:
<u>Step 1: Define</u>
y = 7x + 14
<u>Step 2: Identify</u>
We see a linear equation (proportional relationship). Therefore, we have a linear equation.
Explanation: This is a linear equation because it's written in slope-intercept form or <em>y = mx + b</em> where the multiplier or the coefficient of the x-term represents the slope of the line and the<em> b</em> represents the constant term.
So the slope will be the coefficient of the <em>x-term</em> which means the number that is in front of the <em>x</em> which in this case is -5/4.
The y-intercept is the constant term which is +8
Answer:
A
Step-by-step explanation:
First, we need to find the unknown angle of the triangle.
40 + 20 = 60
180 - 60 = 120
So the unknown angle is 120.
Then, we can use the law of sines to create a proportion.
sin(120)/8 = sin(40)/a
Then, we can simplify this.
a is about 5.9, or answer choice A.
