Answer:

x = 39

Step-by-step explanation:

Let's recall that the interior angles of a triangle always add up to 180 degrees.

Upon saying that, we have:

102 + 39 + x = 180

x = 180 - 102 - 39

x = 39

The value of x is 39 degrees

For each order pair (x,y) , determine whether it is a solution to the inequality 4x-6y_< - 18

anyanavicka [17]

Solution:

Given:

$4x-6y\leq-18$

To determine if an ordered pair is a solution, we substitute the x and y-values into the inequality and check if it is true.

Thus,

$\begin{gathered} For\text{ the point }(-9,-2) \\ x=-9,y=-2 \\ 4x-6y\leq-18 \\ 4(-9)-6(-2)=-36+12=-24 \\ Since\text{ }-24$

$\begin{gathered} For\text{ the point }(0,3) \\ x=0,y=3 \\ 4x-6y\leq-18 \\ 4(0)-6(3)=0-18=-18 \\ Since\text{ }-18=-18,\text{ then }(0,3)\text{ is a solution} \end{gathered}$

$\begin{gathered} For\text{ the point }(5,-3) \\ x=5,y=-3 \\ 4x-6y\leq-18 \\ 4(5)-6(-3)=20+18=38 \\ Since\text{ }38>-18,\text{ then }(5,-3)\text{ is not a solution} \end{gathered}$

$\begin{gathered} For\text{ the point }(8,5) \\ x=8,y=5 \\ 4x-6y\leq-18 \\ 4(8)-6(5)=32-30=2 \\ Since\text{ }2>-18,\text{ then }(8,5)\text{ is not a solution} \end{gathered}$

Therefore, the correct answers are selected as shown below;

If f(x)=7x-7 what is f(8)+f(4)

NARA [144]

Given Function is

f ( x ) = 7x - 7 ------- eqn ( 1 )

Now , put the value of x = 8 in eqn ( 1 )

f ( 8 ) = 7 ( 8 ) - 7
f ( 8 ) = 56 - 7
f ( 8 ) = 49 ------- eqn ( 2 )

Now , put the value of x = 4 in eqn ( 1 )

f ( 4 ) = 7 ( 4 ) - 7
f ( 4 ) = 28 - 7
f ( 4 ) = 21 ------- eqn ( 3 )

<h3 />

From eqn ( 2 ) nd eqn ( 3 ) we get,

f ( 8 ) + f ( 4 )
49 + 21
