Answer:

11

Step-by-step explanation:

Step by step solution :

Step  1  :

Pulling out like terms :

1.1     Pull out like factors :

  2x - 22  =   2 • (x - 11)

Equation at the end of step  1  :

Step  2  :

Equations which are never true :

2.1      Solve :    2   =  0

This equation has no solution.

A a non-zero constant never equals zero.

Solving a Single Variable Equation :

2.2      Solve  :    x-11 = 0

Add  11  to both sides of the equation :

                     x = 11

One solution was found :

                  x = 11

Two hours after a truck leaves phoenix traveling 45 miles per hour, a car leaves to overtake the truck. if it takes the car ten
Sergeeva-Olga [200]

Answer:

The correct answer is 54 miles per hour

Step-by-step explanation:

To solve this problem we have to use the formula of

Speed=Distance/time

Both, car an truck made the same distance,  so

Distance car=Speed car*time car

Distance truck =Speed truck*time truck  

Distance car=Distance truck

So Speed car*time car =Speed truck*time truck  

Speed car =Speed truck* time truck /time car

Time truck = time car +2 ( truck leaves 2 hours before)

Time car =10

Speed car =45 miles per hour* 12 /10

Speed car = 54 miles per hour

Based on the graphs of the equations y = x + 7 and y = x2 – 3x + 7, the solutions are located at points:
Triss [41]

The correct option is A. (4, 11) and (0, 7).

The solution of the equations y = x + 7 and y = x² – 3x + 7, the solutions are located at points: (4, 11) and (0, 7).

<h3>What is the system of linear equation?</h3>

Estimate the y-intercept, slope, and express the equation in the form of the y-intercept (y = mx + b) to find the graphed equation. The slope is the difference between the y- and x-axis values.

A graph equation is an equation in graph theory where the unknown is a graph. Isomorphic ideas are one of the key issues in graph theory.

The equations are; y = x + 7 and y = x² - 3x + 7

At the solution, the u-values are equal, which gives;

y = y

x + 7 = x² - 3·x + 7

x² - 3·x + 7 - (x + 7) = 0

x² - 4·x = 0

x·(x - 4) = 0

x = 4, or x = 0

When x = 4, y = 4 + 7 = 11

When x = 0,

         y = 0 + 7 = 7

Therefore, the solution for the equations  y = x + 7 and y = x² - 3x + 7 are are located at points: (4, 11) and (0, 7).

The space shuttle travels at 28000 mph while orbiting the earth. How far does the shuttle travel in feet per day
STatiana [176]

We are given the speed of the shuttle as:

speed = 28,000 miles / hour

 

We know that:

1 mile = 5280 ft

24 hour = 1 day

 

Therefore by conversion:

speed = (28,000 miles / hr) * (5280 ft / 1 mile) * (24 hr / day)

speed = 3,548,160,000 ft / day

 

In 2 significant figures:

<span>speed = 3.5 x 10^9 ft / day</span>
