Your answer is A) because the rise/run is -2/4x, which simplifies to -1/2x, which is <em>option A)</em>.

Dario's salary is <em>B) $12 per hour</em>. This is because, in 5 hours, Dario makes 60 dollars. If you find the unit rate of $60 in 5 hours, the answer is $12 per hour.
{3}
A) Between <em>x = -6</em> and <em>x = -2</em>

Answer:
Step-by-step explanation:
Given is a triangle RST and another triangle R'S'T' tranformed from RST
Vertices of RST are (0, 0), (negative 2, 3), (negative 3, 1).
Vertices of R'S'T' are (2, 0), (0, negative 3), (negative 1, negative 1).
Comparing the corresponding vertices we find that x coordinate increased by 2 while y coordinate got the different sign.
This indicates that there is both reflection and transformation horizontally to the right by 2 units
So first shifted right by 2 units so that vertices became
(2,0) (0,3) (-1,1)
Now reflected on the line y=0 i.e. x axis
New vertices are
(2,0) (0,-3) (-1,-1)
We can one theorem to help us find rational roots of this polynomial.
2x^3 + x^2 - 4x - 2
We'll use Descartes' rule of signs.
Because there is 1 sign change, 1 of the 3 roots will be positive.
Now we can make the value of x -1 to see how many negative roots there will be.
-2 + 1 + 4 - 2
There are 2 sign changes, so we know there will be 2 negative roots.
Because of this, we should have 3 real, rational roots.
Answer:
65 miles
Step-by-step explanation:
y=55+0.35x
77.75 = 55+0.35x
77.75 - 55 = 0.35x
22.75 = 0.35x
22.75 ÷ 0.35 = 0.35x ÷ 0.35
65 = x
x = 65
