Answer:
A)
All Real Numbers
Step-by-step explanation:
Every integer is a real number.
P(-2) and P(3) is telling you to substitute the “x” in the equation for those two.
So P(-2)=(-2)^3 - (-2)^5 =24
and
P(3)= (3)^3 - (3)^5 = -216
hope this helps !
Answer:
x = 7.6
Step-by-step explanation:
We know the opposite side and the adj side and this is a right triangle
tan theta = opp / adj
tan 66 = 17/x
x tan 66 = 17
x = 17 /tan 66
x=7.56888
To the nearest tenth
x = 7.6
Answer:
Let x = cube root of 400
Using a calculator x = 7.368 to 3 decimal places
So: 7 < x < 8
Answer:
x - intercept = 1
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Here m = - 3 and c = 3, thus
y = - 3x + 3 ← equation of line
The x- intercept has a y- coordinate of zero.
let y = 0 in the equation and solve for x, that is
- 3x + 3 = 0 ( subtract 3 from both sides )
- 3x = - 3 ( divide both sides by - 3 )
x = 1 ← x- intercept
