Please help! What is the product in the form ax^2+bx+c​

Mathematics
1 answer:
Firlakuza [10]3 years ago
3 0

Answer:

a=2, b=2, c=-12

Step-by-step explanation:

Since it's in factor form, you would first distribute using foil to get 2x^{2} -4x+6x-12 and then combine like terms when necessary. In this case, the fully simplified version is 2x^{2} +2x-12. Therefore your a is 2, b is 2, and c is -12.

4z +  2 = 10z - 1

Add sides 1

4z  + 2  + 1 = 10z - 1 + 1

4z + 3 = 10z

Subtract sides 4z

- 4z + 4z + 3 =  - 4z + 10z

3 = 6z

6z = 3

Divide sides by 6

\frac{6z}{6}  =  \frac{3}{6}  \\

z =  \frac{1}{2}  \\

3y = y + 3

Subtract sides y

- y + 3y =  - y + y + 3

2y = 3

Divide sides by 2

\frac{2y}{2}  =  \frac{3}{2}  \\

y =  \frac{3}{2}  \\

Thus the correct answer is :

a) \: y =  \frac{3}{2}  \: , \: z =  \frac{1}{2}  \\

Miguelle is deciding which type of heating system to put in his house. An oil system costs $2700 to install and
stellarik [79]

Answer: (9, 10800)

Step-by-step explanation:

We will first let x be the number of years and y be the total cost.

In that case, let's plug in the values for each into the equation <em>y=mx+b, </em>where m is the slope and b is the y-intercept.

The y-intercept will be the <u>value we start with before any years pass</u>, so it will be the <u>installation cost</u>. The slope is <u>how fast the total cost will increase</u>. Since the <u>operation costs</u> have to be added on every year, it will be our slope.

With that in mind, let's create both of our equations:

  1. y = 900x + 2700 (Oil system)
  2. y = 200x + 9000 (Solar system)

Since y is solved for in the first equation, we can substitute it into the second equation:

900x + 2700 = 200x + 9000

700x + 2700 = 9000 <em>[Subtracting 200x from both sides]</em>

<em />700x = 6300 <em>[Subtracting 2700 from both sides]</em>

<em />x = 9 <em>[Dividing both sides by 700]</em>

<em />

We can now substitute 9 for x in any equation and solve for y. Here I substituted it into the first one:

y = 900(9) + 2700

y = 8100 + 2700 <em>[Multiplying]</em>

<em />y = 10800 <em>[Adding]</em>

Hence, the solution to this linear system is (9, 10800).
