x^2 in the function that you typed is x * x ( x multiplied by x). It represents a second degree because there are only 2 "x"s multiplied together. If there were 3 "x"s multiplied together, we would have x^3. Since the highest exponent in this function is 2 (in x^2), we call this function a 2nd degree polynomial.
In the second step while distributing she made a mistake
It should have been
2x^2 -4x -6x +18 = 9x - 27
So answer should be
She did not use the distributive property correctly
We know
In a function
x represents the input and y represents output
So
x is time
So
f(30) represents distance traveled in 30mins
The range is the difference between the lowest number and the highest number.
If x was the lowest number, then the highest number shown is 49
X = 49- 58 = -9
If x was the highest number, the lowest number given is 3
X = 3 + 58 =61
The two values would be -9 and 61
Answer:
b) 94
Step-by-step explanation:
The Total Degree of a Triangle is 180 degrees. Knowing this, set up an equation.
68+26+x=180.
x is the complementary angle of the "?" angle.
Solve the equation.
94+x=180
x=86
Then Subtract 86 from 180 to find "?"
180-86=94
I hope this helps!
