Answer:
f(x) = -3x + 4
Second option
Step-by-step explanation:
In function notation, the <u>"y" variable is isolated and replaced with "f(x)"</u>.
Isolate "y" by keeping "y" on the left and moving everything else to the right. To move something, do its reverse operation to both sides.
9x + 3y = 12
9x + 3y - 9x = 12 - 9x Do -9x on both sides
3y = -9x + 12
3y/3 = -9x/3 + 12/3 Divide by 3 on both sides
y = -3x + 4 Change to function notation
f(x) = -3x + 4 Answer
Answer:
B. Step 4 is incorrect , it should be 
Step-by-step explanation:
6x-1= -2x+9
Step 1
Collect like terms and change signs if you move anything from one side to the other; 6x+2x = 9+1
Step 2: Add like terms on both sides
8x = 10
Step 3: To remain with just x on one side, divide both sides by 8 and it becomes;
The two 8s cancel each other and you remain with 
2/9 is an irrational number because it is not a real number
If you divide it becomes a repeating decimal which is not rational

It’s D. 4
Step-by-step explanation:
GOOD LUCK HOMIE AND USE A CALCULATO ;)
Answer:
a)Numerator has 3 terms
c)Denominator includes a coefficient of 2
Step-by-step explanation:
Given the expression in the question
-10x² + 15x + 3 / (2x² + 4)
<h3>
1) </h3><h3>
Numerator has 3 terms</h3>
Numerator is the upper part of fraction which in this case is -10x² + 15x + 3 and a term can be a signed number, a variable, or a constant multiplied by a variable or variables. Each term in an algebraic expression is separated by a + sign or - sign.
<h3>2) </h3><h3>Denominator includes a coefficient of 2 </h3>
Denominator is the lower part of fraction which in this case is 2x² + 4 and coefficients are the constants by which the variables are being multiplied.
