Answer:
x-intercept = (4,0)
Step-by-step explanation:
Slope = 1/2
y-intercept = -2
x-intercept =?
Step 1 ; Use the given information to derive the equation of the line.
Substitute values into ; y=mx+b
Where m = slope
b = y-intercept
Equation = 
Step 2 ; Calculate the x-intercept
Arrange the equation in standard form ; Ax +By = C
Let y = 0
Cross Multiply
So ; (4,-2)
Answer:
B
Step-by-step explanation:
y-y1=m(x-x1)
y-1=4(x-4)
1/3 x 1/5 = 1/15 in its simplest form
Answer:
The number of tickets is increasing by 97% each year
Step-by-step explanation:
Answer:
the answer to the question is 8x⁴- 5x²y² - 6y⁴
Step-by-step explanation:
the normal way of using BODMAS is apply to all polynomial equations.
subtracting -6x⁴- 3x²y² + 5y⁴ from 2x⁴ - 8x²y² - y⁴.
polynomial of the same degree is very easy to calculate. this equation is having the same degree of polynomial all through, therefore:
Applying Bracket to the equation
2x⁴ - 8x²y² - y⁴- ( -6x⁴- 3x²y² + 5y⁴)
Open the bracket
2x⁴ - 8x²y² - y⁴ +6x⁴+3x²y² - 5y⁴
collects the likes terms
2x⁴ +6x⁴- 8x²y² +3x²y² - 5y⁴ - y⁴
The final answer is =
8x⁴- 5x²y² - 6y⁴
