Answer: 35 more times
How: (if she gets 60 points for each grocery store visit then first do 2580-480=2100. she still needs 2100 points so then 2100/60 = 35 grocery visits!)
Answer: magnesium >potassium hope it helps
Let's solve for y.<span><span>2+<span>16y</span></span>=<span><span>3x</span>+4</span></span>Step 1: Add -2 to both sides.<span><span><span><span>16y</span>+2</span>+<span>−2</span></span>=<span><span><span>3x</span>+4</span>+<span>−2</span></span></span><span><span>16y</span>=<span><span>3x</span>+2</span></span><span>Step 2: Divide both sides by 16.
16y/16 = 3x+2/16
Y=3/16x +1/8</span>
The question is asking for an absolute value inequality that represents all real numbers less than
![4](https://tex.z-dn.net/?f=4)
units from
![6](https://tex.z-dn.net/?f=6)
in any direction on the number line.
This can be written as
![2 \ \textless \ |x| \ \textless \ 10](https://tex.z-dn.net/?f=2%20%5C%20%5Ctextless%20%5C%20%7Cx%7C%20%5C%20%5Ctextless%20%5C%2010)
.
![4](https://tex.z-dn.net/?f=4)
numbers from
![6](https://tex.z-dn.net/?f=6)
to the left is or
![6-2](https://tex.z-dn.net/?f=6-2)
, or
![4](https://tex.z-dn.net/?f=4)
.
![4](https://tex.z-dn.net/?f=4)
numbers to the right of
![6](https://tex.z-dn.net/?f=6)
is
![6+4](https://tex.z-dn.net/?f=6%2B4)
, or
![10](https://tex.z-dn.net/?f=10)
. Therefore, the inequality can only allow real numbers whose absolute values fall between
![2](https://tex.z-dn.net/?f=2)
and
![10](https://tex.z-dn.net/?f=10)
.
Consider this option:
according the condition the graph mx²-5x-2 have no x-interception.
It means that D<0:
D=25+2*4*m=25+8m<0; ⇒ 8m+25<0; ⇔ m<-25/8; ⇔ m<-3.125.
answer: m∈(-oo;-3.125).
