Let f(x)=2x^2+7x-5 and g(x)=-8x^2-3x+5 what is g(x)+f(x)
ser-zykov [4K]
F(x) = 2x² + 7x - 5
g(x) = -8x² - 3x + 5
g(x) + f(x) = -8x² - 3x + 5 + 2x² + 7x - 5 = - 6x² + 4x

Answer: -6x² + 4x

write a function to model the volume of a rectangular prism if the length is 10cm and the sum of the width and height is 18cm.
Musya8 [376]
Let the length be l, width w and height h, then
Volume = length x width x height
l = 10cm, w + h = 18cm

V(h) = 10(18 - h)h = 180h - h^2
V(h) = 180h - h^2

What is the equation in slope intercept form of the perpendicular bisector of the given line segment?
andreev551 [17]

Answer:

y = -4x - 6

Step-by-step explanation:

The equation of a line in point-slope form.

y - y_1 = m(x - x_1)

is the equation of the line containing point (x1, y1) and having slope, m.

The given point of the perpendicular bisector is (-1, -2), so in this case, x1 = -1, and y1 = -2.

We need the slope of the perpendicular bisector. First we find the slope of the segment. We start at point (-5, -3). We go up 1 unit and 4 units to the right, and we are at another point on the segment. Since slope = rise/run, the slope of the segment is 1/4. The slopes of perpendicular lines are negative reciprocals, so the slope of the perpendicular bisector is the negative reciprocal of 1/4, so for the perpendicular bisector, m = -4.

Now we use the equation above and our values.

y - y_1 = m(x - x_1)

y - (-2) = -4(x - (-1))

y + 2 = -4(x + 1)

y + 2 = -4x - 4

y = -4x - 6
