Which is a valid prediction about the continuous function f(x)?
f(x) > 0 over the interval [5,00).
f(x) < 0 over the interval [-1, ).
f(x) > 0 over the interval (-0, 1).
f(x) < 0 over the interval (-00. –1).

f(x) < 0 over the interval (-00. –1).

Step-by-step explanation:

thats a valid

d) 30 units^2

area of rectangle = l × b

we know,

length = 10 unit

breadth = 3 unit

applying the formula,

= l × b

= 10 × 3

= 30 unit^2

pls mark as brainliest

a) y = -3x +2

b) y = 1/2x -6

these 2 can be combined into one equation.

-3x +2 = .5x -6

8 = 3.5x

x = 8 / 3.5 = 2.2857142857

y = -3 * (8 / 3.5) +2

y = (-24 / 3.5) + 2

y = -4.8571428571
