Answer:
Equation for area = 36 = [1/2]x[2x - 1]
Step-by-step explanation:
Given:
Area of triangle = 36 m²
Length of base = 2(Height) - 1
Find:
Equation for area
Computation:
Assume;
Height = x
Area of triangle = (1/2)(b)(h)
36 = (1/2)[2(x) - 1][x]
36 = [1/2]x[2x - 1]
Equation for area = 36 = [1/2]x[2x - 1]
Use the points and do y2-y1 divided by x2-x1
You will get -2 which is the m (slope)
Substitute one of the points into the y and x to get the b (y-intercept)
You will get -6
Put everything into the equation
y=-2x-6
Answer:
Step-by-step explanation:
So we multiply 7 by 4, and get 28. Then we multiply 2 by 12, and get 24. Next we give both terms new denominators 12 × 4 = 48.
<span>The correct answer is D) g(x) = -(x + 2)^2. The given formula F(x) = x^2 creates a parabola that is open at the top. To reflect this figure across the x-axis and have it open at the bottom, the y-position of the figure on the coordinate system for every x value, which is F(x) = y = x^2 has to be inverted. This is done by negating y and respectively x^2, so to reflect the figure on the x-axis the formula would now look like this: F(x) = -y = -x^2. To move any parabola two units to the left and thereby have its root be at -2, you would simply subtract -2 from every x-position of the figure in the coordinate system. For an inverted parabola like this one the value to move it on the x-axis has to be added instead and this results in the formula from answer D: g(x) = -(x+2)^2</span>
