Y=_x+4<br> x + 2y =<br> 8<br> How many solutions dose this linear system have
jeyben [28]

Answer:

X=-1, y=4

Step-by-step explanation:

y = x + 4 \\ x + 2y = 8 \\  =  =  =  =  =  =  =  =  =  =  =  = \\ y - x = 4 \\ x + 2y = 8

by using eliminating property

3y = 12 \\ y = \frac{12}{3}    = 4

by substitution

X=-1

Which of the following best describes the expression 7(y + 5)?
damaskus [11]

Answer: LAST OPTION.

Step-by-step explanation:

To solve this exercise is important to remember the following definitions:

  1. The sum is the result obtained when we solve an addition.
  2. The product is the result obtained when we solve a mutiplication.
  3. Given a multiplication (a)(b)=c, "a" and "b" are factors and "c" is the product.

In this case, you have this expression:

7(y + 5)

Notice that the there is an addition of two terms (y and 5) inside the parentheses.

Outside the parentheses you can notice that the number 7 is multiplying the sum of the terms  mentioned before.

Therefore, you can conclude that the best description for this expression is:

<em>The product of a constant factor of seven and a factor with the sum of two terms.</em>

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>
