Answer:
this question
Step-by-step explanation:
3x + 2y=-10 equation 1
y=-x -4 equation 2
use the substitution method of elimination to get the answer to the question.
*using substitution
substitute equation 2 in one and we get
3x +2(-x-4)=-10
3x- 2x-8=-10
x=-2 and y=-2
Answer:
B
Hi there!
We can find the zeros of a function by solving f(x) = 0. We find the following:

Add 300 to both sides.

Divide by 3.

Take the root and minus root of both sides.

Therefore, the zeros are
x = 10 and x = -10.
~ Hope this helps you!
Answer:
Linear Proportional Relationship
General Formulas and Concepts:
<u>Algebra I</u>
- Linear - Any degree of 1 in the form of y = mx + b or Ax + By = C
- Nonlinear - Any degree higher than 1
Step-by-step explanation:
<u>Step 1: Define</u>
y = 2x + 3
<u>Step 2: Identify</u>
We see we have a linear equation in y = mx + b. We can also see that it is a degree of 1. Therefore, it is a Linear proportional relationship.
