Solve for x. 8 6 X A 100 В 10 С 5.3 D 14

1. Evaluate each expression when x = -2 and y = 3.

borishaifa [10]

a) 3(-2) + 4(3) = -6 + 12 = 6

b) 2(-2) -3(3) +5 = -4 -9 + 5 = -8

c) 4(-2) -(3) = -8 -3 = -11

d) -(-2) -2(3) = 4 -6 = -2

e) (1/2)(-2) +(3) = -1 +3 = 2

f) (2/3)(3) -(1/2)(-2) = 2 + 1 = 3

Which absolute value function, when graphed, represents the parent function, f(x) = |x|, reflected over the x-axis?

Gala2k [10]

Reflecting the point (x, y) over the x-axis transforms it to the point (x, -y). Then the points (x, f(x)) on the graph of f(x) will be transformed to (x, -f(x)) when the graph is reflected over the x-axis.

The reflection of the function f(x) = |x| is -f(x) = -|x|. If we name the reflected function f(x), we have
f(x) = -|x|

Math help? One question?

Lera25 [3.4K]

My triangle solver says EF ≈ 7.5 ft.

_____
The law of cosines is usually used for this.

EF^2 = DE^2 +DF^2 -2*DE*DF*cos(D)
.. = 6^2 +11^2 -2*6*11*cos(40°)
.. ≈ 55.88

EF ≈ √55.88 ≈ 7.5 . . . ft
