Answer:
neither because A quadratic function is one of the form f(x) = ax² + bx + c, where a, b, and c are numbers with a not equal to zero. The graph of a quadratic function is a curve called a parabola. A parabola intersects its axis of symmetry at a point called the vertex of the parabola. You know that two points determine a line.
Answer:
12 ft²
Step-by-step explanation:
area = length * width
area = 4 ft * 3 ft
area = 12 ft²
Answer:
True
Step-by-step explanation:
A matrix needs to be in a same size
In order to be increased, decreased, etc
So it is true
It won't be false trust me ;)
I hope this helps you :)
Answer:
9x -6
Step-by-step explanation:
f(x)= 2x+3 and g(x)= 7x-9
f(x) + g(x) = 2x+3 + 7x-9
Combine like terms
= 2x+7x +3-9
=9x -6
Answer: y = 1.2x + 1.4
Step-by-step explanation:
1. Write down the coordinates of the first point. Let's assume it is a point with x₁ = -2and y₁ = -1.
2. Write down the coordinates of the second point as well. Let's take a point with x₂ = 3 and y₂ = 5.
3. Use the slope intercept formula to find the slope:
m = (y₂ - y₁)/(x₂ - x₁) = (5-1)/(3-2) = 4/1 = 1.2
4. Calculate the y-intercept. You can also use x₂ and y₂ instead of x₁ and y₁ here.
b = y₁ - m * x₁ = -1 - 1.2*-2 = 1.4
5. Put all these values together to construct the slope intercept form of a linear equation:
y = 1.2x + 1.4
