The answer is c because he begins at 3 points. He then loses 9. So subtract 9 from 3 and you end up with -6
Answer:
The table is a quadratic function
Step-by-step explanation:
Given
The attached table
Required
Tell if it is a quadratic function
The difference in the x values are uniform (i.e. difference of 1), so the following method can be applied.
(1) Subtract adjacent y values.




(2) Subtract adjacent differences in (1) above



Notice the calculated differences in (2) are the same.
<em>Hence, the table is a quadratic function</em>
Answer:
10/2x^2+2x+2=2x-1+y
y=5x^2+1
Step-by-step explanation:
Answer:
-15
Step-by-step explanation:
Multiply: (-3)8= -24
Add: -4+6+3+1+0+2+1= 9
Subtract: 9-24= -15
If the temperature is the same in Farenheit and Celsius, the variable F is equal to the variable C in the equation. Thus, you'll just need to replace one or both variables in the original equation and solve for the single variable. I'll just use x as the variable here:
F = 1.8C + 32
x = 1.8x + 32
subtract x from both sides
0 = 0.8x + 32
subtract 32 from both sides
-32 = 0.8x
divide both sides by 0.8
-40 = x
So, since we know x = -40 degrees, we also know that F = -40° and C = -40° too.
