Solve the system by substitution.
y = 8x
y=10x – 4
Submit Answer
How

(2,16)

Step-by-step explanation:

y=8x(i)

y= 10x-4(ii)

Substituting the value of y=8x in equation (ii)

8x=10x-4

8x-10x=-4

-2x= -4

x=2

Now, substituting the value of x= 2 in equation (i)

y=8x=8(2)=16

Solution of the system is (2,16)

logv3(x+2)=1

rewrite in exponential form:

logb(x) = y is equal to b^y =x

b = 3, y = 1

now solve for x:

3^1 = x+2)

x = 3-2

x = 1

see the picture for the graph.

the volume is the product of the area of the base, 3x(3x+4), and the height, 3x-1
