What is the solution to this inequality?<br><br> −4x−8>−20

77julia77 [94]

Answer:

x < 3

Step-by-step explanation:

−4x − 8 > −20

Add 8 to both sides.

-4x > -12

Divide both sides by -4. Remember that when you multiply or divide both sides of an inequality by a negative number, the direction of the inequality sign changes.

-4x/(-4) < -12/(-4)

x < 3

An athlete ran a sprint of 100 ft in 3.1 s. At what speed was the athlete running in miles per hour? Round to the nearest mile p

nordsb [41]

Answer:

22 miles per hour

Step-by-step explanation:

we know that

The speed is the ratio of distance by the time

Let

d -----> distance in feet

t ----> time in seconds

s ----> the speed in ft/sec

$s=\frac{d}{t}$

we have

$d=100\ ft\\t=3.1\ sec$

substitute

$s=\frac{100}{3.1}$

$s=32.26\frac{ft}{sec}$

Remember that

$1\ mi=5,280\ ft$

$1\ h=3,600\ sec$

Convert ft/sec to mi/h

$s=32.26\frac{ft}{sec}=32.26\frac{(1/5,280)}{(1/3,600)}=32.26(\frac{3,600}{5,280})=22\ \frac{mi}{h}$

Graph the line by locating any two ordered pairs that satisfy the equation y = 1/4x+1

Tom [10]

How I would do it is place a point at 1 then go up 1 over 4 because of your slope 1/4. Same as for going down except down 1 over 4. Hope this helped:)
