Answer:

Step-by-step explanation:

2x to the power of 2 + x = ? When x=9

(2x)^2 + x

= 4x^2 + x

When x = 9

= 4(9)^2 + 9

= 4(81) + 9

= 324 + 9

= 333

Answer: True

---------------------------------

Work Shown:

Follow PEMDAS in reverse to solve for q
22q - 7 < 37
22q - 7+7 < 37+7 ... add 7 to both sides
22q < 44
22q/22 < 44/22 ... divide both sides by 22
q < 2

PLEASE ANSWER ASAP
mote1985 [20]

Answer:

y = 2(3)^{x}

Step-by-step explanation:

For the exponential function in the form

y = ab^{x}

Use ordered pairs from the table to find a and b

Using (0, 2 ), then

2 = ab^{0} ( b^{0} = 1 ) , thus

a = 2, so

y = 2b^{x}

Using (1, 6 ) , then

6 = 2b ( divide both sides by 2 )

b = 3

Thus the exponential function is

y = 2(3)^{x}
