The expression is equivalent to -8y + 7x.

Given

Expression; (-3y - x) - (5y - 8x)

<h3>How to find the equivalent expression?</h3>

To find the equivalent expression multiply the expression and add and simplify.

Then,

The expression is equivalent to;

 (-3y - x) - (5y - 8x)

-3y - x - 5y + 8x

-8y + 7x

Hence, the expression is equivalent to -8y + 7x.

Solve and graph the inequality. −x4−6≥−8 {"version":"1.1","math":"-x4-6≥-8"} Question 6 options: x ≤ 8 x &lt; –4 x &gt; 8 x ≥ –8
anastassius [24]

Answer:

x \geq  -4

Step-by-step explanation:

The given inequality is

-x(4-6) \geq -8

To solve this inequality, we just have to isolate x

-x(-2) \geq -8

2x\geq -8\\x\geq \frac{-8}{2}\\ x\geq -4

Therefore, the solutions for this inequality is x \geq  -4.

If we graph this inequality, the solution would be like the image attached.

The sum of a number and 2 times the number is 21. Find the number.
sveta [45]
To find the number you would start by writing out the equation using x as the number. The equation would be x+2x=21. The first step to solve this equation would be to combine like terms, making the equation 3x=21. Finally, you would divide both sides by three, making your answer x=7.

A spring is hanging from a ceiling. The length L(t) (in cm) of the spring as a function of time t (in seconds) can be modeled by
Zanzabum

Answer:

  L(t) = 5·sin(πt) +7

Step-by-step explanation:

The middle of the oscillation of the given function occurs when t=0. At that point, ...

  L(0) = d = 7

The next maximum of the oscillation occurs when the argument of the sine function is π/2.

  b·t = π/2

  b = π/(2t) = π/(2·0.5) = π

At that maximum, the length is 12, so we have ...

  L(0.5) = a·sin(0.5π) +7 = 12

  a = 5

The function L(t) is ...

  L(t) = 5·sin(πt) +7
