Answer:
2 and 7/10
Step-by-step explanation:
Answer:
y=6(x+1)^(2)-16
Step-by-step explanation:
Use the formula x=-b/2a
Plug it in for x to get y. That will give you the vertex. Plug the numbers in where they go. There will be one number left that hasn't been filled out. The first number in the equation id 6, so it goes out front.
Answer:
Equation:
Step-by-step explanation:
The equation that represents a direct variation between variable x and variable y is given as . Where, k is the constant of proportionality.
Find the value of k given that x = ⅓ and y = 12.
Plug the values into the equation.
Multiply both sides by 3
Substitute the value of k into
Equation:
It is a solution of a system of linear equations
Answer: x=35
The supplementary angle with 40 and 40 degrees tells me the triangles angle is 100 degrees (40 + 40 + 100 = 180 degree)
2x + 30 = 100
-30 -30 subtract 30 from both sides
___________
2x = 70 Divide both sides by 2 to isolate x
X = 35
