Simplify x+1-2x+1−2 to x-1x−1.
x-1=4
x−1=4
2 Add 11 to both sides.
x=4+1
x=4+1
3 Simplify 4+14+1 to 55.
x=5
x=5
Add 11 to both sides.
x=2+1
x=2+1
2 Simplify 2+12+1 to 33.

An expression can either be positive, negative or none.
The sign of the expression is neither positive nor negative.
The fraction expression is given as:
[tex]\dfrac{23}{45} + \left(-\dfrac{23}{45}\right)[/tex]
Open the bracket
[tex]\dfrac{23}{45} + \left(-\dfrac{23}{45}\right) = \dfrac{23}{45}-\dfrac{23}{45}\right[/tex]
Take LCM
[tex]\dfrac{23}{45} + \left(-\dfrac{23}{45}\right) = \dfrac{23 - 23}{45}[/tex]
Simplify the numerator
[tex]\dfrac{23}{45} + \left(-\dfrac{23}{45}\right) = \dfrac{0}{45}[/tex]
Divide 0 by 45
[tex]\dfrac{23}{45} + \left(-\dfrac{23}{45}\right) = 0[/tex]
0 is neither positive nor negative.
Hence, the sign of the expression is neither positive nor negative.

Answer:
[tex]\huge\boxed{y=\dfrac{4}{3}x-1}[/tex]
Step-by-step explanation:
Let
[tex]k:y=m_1x+b_1\\l:y=m_2x+b_2[/tex]
then
[tex]k\perp l\iff m_1m_2=-1\to m_2=-\dfrac{1}{m_1}\\\\k\ ||\ l\iff m_1=m_2[/tex]
==========================================
We have:
[tex]y=-\dfrac{3}{4}x-3\to m_1=-\dfrac{3}{4}[/tex]
Let
[tex]y=m_2x+b_2[/tex]
Therefore
[tex]m_2=-\dfrac{1}{-\frac{3}{4}}=\dfrac{4}{3}\Rightarrow y=\dfrac{4}{3}x+b_2[/tex]
Substitute
[tex](0,\ -1)\to x=0;\ y=-1[/tex]
[tex]-1=\dfrac{4}{3}\cdot0+b_2\\\\b_2=-1[/tex]

Answer:
d. Right 5 and down 3
Step-by-step explanation:
If you have a given graph and then find that it is altered, the changes to the x (something added to or subtract from x) will be on the graph by translating (sliding) the graph left or right. Horizontal changes are probably the opposite of what they seem like they should be: x+_ moves the graph left and x-_ moves the graph right.
A number added on to the end of the equation will shift (translation, again) the graph up (a number added on) or down (a number subtracted). So in this case the x-5 moves the graph to the right 5 units and the - 3 at the end of the equation moves the graph down three units.
Given the function f(x) = x2 - x + 7, find each of the following.
f(6)=
f(- 9)=
f(0)
Answer:
37, 79, 7
Step-by-step explanation:
f(6) = 6² -6 +7
36-6+7 is 37
f(-9) = -9² -9+7
81-9+7 is 79
f(0) = 0² -0+7
0-0+7 is 7

Caleb decreases a number by 6 and then multiplies it by 2. He gets the same answer as
when he subtracts 8 from the original number. What is the number?
please answer!!
Answer: 4
Step-by-step explanation: If Caleb starts with 4 and subtracts 6, he'll get -2. -2 times 2, equals -4. If he starts with 4 and subtracts 8, he'll again end up with -4, meaning the original number is 4!
4-6= (-2)
-2*2= (-4)
4-8= (-4)
