Answer:

f(x)= $\frac{1}{4} ^{x} -2$

Step-by-step explanation:

The given function is an exponential function .All the graphs will begin from second quadrant . The exponential graph crosses the ordered pair at (0,-1)

It then decreases slowly as it approaches y=-2.

The point (0,-1) lies on the graph:

$y=\frac{1}{4} ^{x} -2$

Ruby signed up for a frequent-filer program. She receives 3400frequent-flier miles for the first round trip and 1200 miles for a

vovangra [49]

Answer: 8200 miles

Step-by-step explanation:

Based on the question, since she wants to go for five round trips, her first round trip is fixed at 3400 and she will have 4 more additional trips. This can them be calculated as:

= 3400 + 1200x

x = additional trips = 4

We then put the value of x into the equation

= 3400 + 1200x

= 3400 + 1200(4)

= 3400 + 4800

= 8200

She'll have 8200 mile after 5 round trips

One desk requires 84 inches of a type of trim. Find the lenght of trim needed in inches of 5 desks. Then convert yours answer to

Crazy boy [7]

420 inches and 35 feet

length of trim required = 84 × 5 = 420 inches

using 12 inches = 1 foot then

$\frac{420}{12}$ = 35 feet

Vernon's work for finding the value of x is shown below. Lines A C and B D intersect at point E. Angle A E D is (16 x + 8) degre

Marta_Voda [28]

Answer:

<em>No, he should have set the sum of ∠AED and ∠DEC equal to 180°, rather then setting ∠AED and ∠DEC equal to each other</em>

Step-by-step explanation:

Find the diagram attached

If line AC and BD intersects, then m<AED + m<DEC = 180 (sum of angle on a straight line is 180 degrees)

Given

m<AED = 16x+8

m<DEC = 76 degrees

16x + 8 + 76 = 180

16x + 84 = 180

16x = 180-84

16x = 96

x = 96/16

x = 6

Hence the value of x is 6

Hence the correct option is <em>No, he should have set the sum of ∠AED and ∠DEC equal to 180°, rather then setting ∠AED and ∠DEC equal to each other</em>
