Hello,
Do you mean
h(x)=2x+5
g(x)=8-3x
h(g(x))=h(8-3x)=2(8-3x)+5=16-6x+5=21-6x
h(g(1.5))=h(g(3/2))=21-6*3/2=21-9=12
Answer:
About $17.16
Step-by-step explanation:
$80-$28.50= 51.5
Then you divide that by 3 (for the 3 ties)
1st we should find the point where the line intersects with the axises
put x= 0 , so y= 3 ---- > the 1st point (0,3)
put y=0 , so x = 7.5 ----> the 2nd point (7.5,0)
so it's the first graph on the left
Since width is the smaller value, set width=x. That wold mean that length=x+3. Since Area=width*length, 40=x(3+x). Distribute the x to give you 40=3x+x^2. Set the equation equal to 0 giving you x^2+3x-40=0. Factor the equation to give you (x+8)(x-5)=0. Set each factor equal to 0. x+8=0 gives you x=-8 & x=-5 gives you x=5. Since we're working with lengths of objects, it can't be negative. Therefore, your width is 5. To find length, substitute width into the original expression (x+3). Therefore, length is 5+3=8.
The consecutive integers are i, i+1, i+2, i+3.
3 less than sum of the integers
= i + i +1 + i + 2 + i + 3 - 3 = 4i + 3
