−8x−y=4 ​−8x−y=9 ​​ How many solutions does the system have?

Mathematics
1 answer:
Nutka1998 [239]4 years ago
6 0
-8x - y = 4
-y = 8x + 4
y = -8x - 4....slope = -8, y int = -4

-8x - y = 9
-y = 8x + 9
y = -8x - 9...slope = -8, y int = -9

same slopes, different y int....means parallel lines...no solution <==

** just so u know..
same slopes, same y int = coincident lines = infinite solutions
different slopes, different y int = one solution

Write the absolute value inequality in the form Ix−bIc that has the solution set x≤−9 or x≥−5.
Valentin [98]

Answer:

\large\boxed{|x+7|\geq2}

Step-by-step explanation:

Look at the picture.

|x-a|\geq b\\\\a=\dfrac{-9+(-5)}{2}=\dfrac{-14}{2}=-7\\\\b=-9-(-7)=-9+7=-2\\b=-5-(-7)=-5+7=2\\\\|x-(-7)|\geq2\\\\|x+7|\geq2\\\\Check:\\\\|x+7|\geq2\iff x+7\geq2\ \vee\ x+7\leq-2\qquad\text{subtract 7 from both sides}\\\\x+7-7\geq2-7\ \vee\ x+7-7\leq-2-7\\\\x\geq-5\ \vee\ x\leq-9\qquad CORRECT\ :)

The following proportions were written on the board by Ms. Warren.​
Elenna [48]

Answer:

see explanation

Step-by-step explanation:

A

given

\frac{3.6}{5.7} = \frac{f}{9.5} ( cross- multiply )

5.7f = 34.2 ( divide both sides by 5.7 )

f = 6

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

B

given

\frac{3.6}{5.7} = \frac{16.2}{g} ( cross- multiply )

3.6g = 92.34 ( divide both sides by 3.6 )

g = 25.65

A high school athletic department bought 40 soccer uniforms at a cost of $3,000. After soccer season they returned some uniforms
quester [9]

Interesting problem.

First - let's figure cost of each uniform at purchase.

3,000/40 = $75 each

When some uniforms were returned at $40 - there was a difference of $35 in what they paid and what they rec'd in return. ($75 - 35 = $40)
