\bf \begin{cases} t(x)=3x+1\\ c(x)=x+4\\ c(~~t(x)~~)=[t(x)]+4 \end{cases} \\\\\\ \stackrel{\textit{the crew working 2 shifts, x = 2}}{t(2)=3(2)+1}\implies t(2)=7 \\\\\\ c(~~t(2)~~)=[t(2)]+4\implies c(~~7~~)=[7]+4\implies \boxed{c(7)=11}

Answer:

11

Step-by-step explanation:

The function c(t(x)) means that t(x) equation must be substituted into c(x) as the value x:

c(t(x)) =3\cdot{x}+1+4

if the crew works 2 shifts x=2 and we can substutite into c(t(x)):

c(t(2)) =3\cdot{2}+1+4=11

What is the sum of the interior angles of the polygon shown below?
melisa1 [442]

Given:

The number of sides of given polygon = 4

To find the sum of the interior angles of the polygon.

Formula

The sum of interior angles of any polygon is

Sum = (n-2)(180^\circ)

where, n be the number of sides of the polygon.

Now,

Taking n = 4 we get,

Sum = (4-2)(180^\circ)

or, Sum = 2(180^\circ)

or, Sum = 360^\circ

Hence,

The  sum of the interior angles of the polygon is 360°.

Samantha drew Triangle JKL with the coordinates (2,3), (4, 3) and (5,2). She reflected this image over the x-axis to create an i
zavuch27 [327]

Answer:

J'(2,-3), K'(4, -3) and L'(5,-2)

Step-by-step explanation:

The given triangle has vertices at  J(2,3), K(4, 3) and L(5,2).

The transformation rule for a reflection in the x-axis is:

(x,y)\to (x,-y)

We substitute the points to obtain the coordinates  of the image triangle  J'K'L'

J(2,3)\to J'(2,-3)

K(4,3)\to K'(4,-3)

L(5,2)\to L'(5,-2)

In other words, we negate the y-coordinates of triangle JKL to obtain the coordinates of J'K'L'
