Answer:

Step-by-step explanation:

area of side triangles=2(1/2×6×4)=24 units²

area of 3 rectangles=6×7+2(5×7)==42+70=112 units²

or=(6+5+5)×7=16×7=112 units²

Total surface area=24+112=136 units²

Answer:

The graph in the attached figure

Step-by-step explanation:

we have

x+3y\leq 6

Isolate the variable y

3y\leq 6-x

y\leq 2-(1/3)x

The solution is the shaded area below the solid line

Is below because the symbol of the inequality is less

Is a solid line because the line is included in the solution

The equation of the solid line is y=2-(1/3)x

To graph the solution find the intercepts

Find the x-intercept (value of x when the value of y is equal to zero)

For y=0, x=6 --------> point (6,0)

Find the y-intercept (value of y when the value of x is equal to zero)

For x=0, y=2 -------> point (0,2)

Graph the inequality

see the attached figure

Sorry I need it asap in I will give 5 stars to all the answers
Fantom [35]

Answer:

A. the equality means that the two equations should be equal in a certain x value. Solving the x for these equation gives you the x point where the 2 equations intersect.

B. The x value where the funcionts intersect is x = 1

Step-by-step explanation:

You can solve the x value using natural logarithms.

If you make a table for the two functions you will also see the result:

Value             y = 8^x            y = 2^(x+2)

 -3                    0,00195          0,5

 -2                    0,0156             1

 -1                     0,125               2

  0                     1                      4

  1                      8                     8

  2                      64                  16

  3                      512                  32

Plss show the work<br> 9.3x+450=1800
Lesechka [4]

Answer:

x  = 145.161290323

x ≈ 145.161

Step-by-step explanation:

9.3x + 450 = 1800

       -450        -450

9.3x = 1350

/9.3       /9.3

x = 145.161290323

x ≈ 145.161

Hope this helps!
