Answer:
x = 3
Step-by-step explanation:
j(x) = 4/5(-5) + 7
= -4 + 7
= 3
The expression is 8(6-4)•2 .
Answer:
k=5
Step-by-step explanation:
step 1
Find the equation of the line f(x)
we have the points
(-4,0) and (-2,2)
<em>Find the slope m</em>

Find the equation of the line in point slope form

we have

substitute


Remember that
f(x)=y
so

step 2
Find the equation of the line g(x)
we have the points
(-4,0) and (-2,-10)
<em>Find the slope m</em>

Find the equation of the line in point slope form

we have

substitute


Remember that
g(x)=y
so

Remember that
------> 
therefore
k=5
Answer:
<h2><em><u>448</u></em><em><u> </u></em><em><u>sq.ft</u></em></h2>
Step-by-step explanation:
The following figure is a <em><u>trapezium</u></em><em><u>, </u></em>
<em><u>So</u></em><em><u> </u></em><em><u>Given</u></em><em><u>,</u></em>
Parallel sides of the trapezium = 17ft and 39ft
Height of the trapezium = 16ft
<em><u>Therefore</u></em><em><u>, </u></em>
Area of the trapezium





<em><u>Hence</u></em><em><u>,</u></em>
<em><u>448</u></em><em><u> </u></em><em><u>sq.ft</u></em><em><u> </u></em><em><u>is</u></em><em><u> </u></em><em><u>the</u></em><em><u> </u></em><em><u>area</u></em><em><u> </u></em><em><u>of</u></em><em><u> </u></em><em><u>the</u></em><em><u> </u></em><em><u>trapezium</u></em><em><u> </u></em><em><u>(</u></em><em><u>Ans</u></em><em><u>)</u></em>
