Answers

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!

[tex]\huge\boxed{y=\dfrac{4}{3}x-1}[/tex]

Step-by-step explanation:

Let

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:

Let

Therefore

Solve the system of linear equations by substitution x=5y+2 and x-4y=5

Answers

Answer:

(17,3)

Step-by-step explanation:

Equation 1.

x=5y+2

Equation 2.

x-4y=5

To solve with substitution, it looks like the x-variable in the first equation is already isolated. So, plug the first equation into the x-variable in the second equation.

x-4y=5

(5y+2)-4y=5

y+2=5

y=3

Now that we found y, plug y into one of the equations to solve for x.

x=5y+2

x=5(3)+2

x=15+2

x=17

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.
