Answer:
x < -7
Step-by-step explanation:
to isolate x we need to subtract 2 from both sides. -5-2 is -7, so the answer is x < -7
Answer:
It does not show variation
Step-by-step explanation:
Given
Required
Determine if there's direct variation between x and y
The general form of direct variation is:
Make y the subject of formula in the given parameters;
Compare to
<em>Since they are not of the same form, then the given equation do not show direct variation</em>
What are the answer options
The measure of angle RML is of 130º.
<h3>What is the value of x?</h3>
Angle NML is the sum of angles NMR and RML, hence:
NML = NMR + RML.
The given measures of the angles are:
Hence we can solve the equation for RML to find the measure of angle RML, as follows:
NML = NMR + RML
156 = 26 + RML
RML = 130º.
The measure of angle RML is of 130º.

Answer:
1. 625,000 J
2. 100 J
4. 5 kg
5. √5 ≈ 2.236 m/s
Step-by-step explanation:
You should be aware that the SI derived units of Joules are equivalent to kg·m²/s².
To reduce confusion between <em>m</em> for mass and m for meters, we'll use an <em>italic m</em> for mass.
In each case, the "find" variable is what's left after we put the numbers into the formula. It is what the question is asking for. The "given" values are the ones in the problem statement and are the values we put into the formula. The formula is the same in every case.

1. KE = (1/2)<em>m</em>v² = (1/2)(2000 kg)(25 m/s)² = 625,000 kg·m²/s² = 625,000 J
__
2. KE = (1/2)<em>m</em>v² = (1/2)(0.5 kg)(20 m/s)² = 100 kg·m²/s² = 100 J
__
4. KE = (1/2)<em>m</em>v²
250 J = (1/2)<em>m</em>(10 m/s)² = 50 m²/s²
(250 kg·m²/s²)/(50 m²/s²) = <em>m</em> = 5 kg
__
5. KE = (1/2)<em>m</em>v²
2000 kg·m²/s² = (1/2)(800 kg)v²
(2000 kg·m²/s²)/(400 kg) = v² = 5 m²/s²
v = √5 m/s ≈ 2.236 m/s
