The equality used is Subtraction property of equality

Option A is correct

Step-by-step explanation:

We need to identify which option best explains or justifies Step 1.

Step 1 is: -c = ax^2 + bx

The given equation is: 0 = ax^2 + bx + c

To get the equation for step 1 we need to subtract c on both sides of equation i.e using subtraction property of equality

0-c = ax^2 + bx + c-c

-c = ax^2 + bx

So, The equality used is Subtraction property of equality

Option A is correct.

____ [38]

Answer: - $110

Step-by-step explanation: If Tyler is overdrawn at the bank it means that he has a negative balance. Tylers balance is -$180. If his brother has $70 more than him you need to add the two numbers together.

-$180 + $70 = -$110

Even though Tyler’s brother has more money than Tyler, his brother is still overdrawn by $110. (-$110)

Given f(x)=5x^2-2x and 3x^2+x-4. What is (f+g)(x)?
den301095 [7]

Answer:(f + g)(x) = f (x) + g(x)

= [3x + 2] + [4 – 5x]

= 3x + 2 + 4 – 5x

= 3x – 5x + 2 + 4

= –2x + 6

(f – g)(x) = f (x) – g(x)

= [3x + 2] – [4 – 5x]

= 3x + 2 – 4 + 5x

= 3x + 5x + 2 – 4

= 8x – 2

(f  × g)(x) = [f (x)][g(x)]

= (3x + 2)(4 – 5x)

= 12x + 8 – 15x2 – 10x

= –15x2 + 2x + 8

\left(\small{\dfrac{f}{g}}\right)(x) = \small{\dfrac{f(x)}{g(x)}}(  

g

f

​  

)(x)=  

g(x)

f(x)

​  

 

= \small{\dfrac{3x+2}{4-5x}}=  

4−5x

3x+2

​

Step-by-step explanation:

To find the answers, all I have to do is apply the operations (plus, minus, times, and divide) that they tell me to, in the order that they tell me to.

For number one, you’re decimal is technically after zero. To change your percentage into a real decimal number, move the decimal twice to the left. Then you will get 3.5. 3.5 is also equivalent to 3 1/2. Do the same for numbers 23 and four. For number five, each you need to know that each hole number represents 100%. If you do the math you will realize that 1/2 equals 50%. When you add them together, you get 250%. Do the same for Numbers six, seven, and eight.
