Answer:
y = 56
Explanation:
We label each of the given equations as follows;
4·x + 2·y = 20...(1)
-8·x - 3·y = 16...(2)
Therefore, we are given a simultaneous equation, question
We make 'x' the subject of both equations and equate the result to find the value of 'y' as follows;
For equation (1)
4·x + 2·y = 20
∴ x = (20 - 2·y)/4 = 5 - y/2
x = 5 - y/2
For equation (2), we have;
-8·x - 3·y = 16
∴ x = (16 + 3·y)/(-8) = -2 - 3·y/8
x = -2 - 3·y/8
Equating the two equations of 'x', gives;
5 - y/2 = -2 - 3·y/8
7 = y/2 - 3·y/8 = (4·y - 3·y)/8 = y/8
∴ 7 = y/8
y = 7 × 8 = 56
y = 56
Anna makes arrangements to reuse waste water that has been used in sinks and showers. Which term refers to the waste water that Anna reuses to conserve resources?
Anna reuses _____ to conserve resources.
This is for my Architecture class.
Answer:
Greywater.
Explanation:
Greywater is also known as sullage and it can be defined as any form of gently used wastewater derived from sources within a residential or office building such as showers, washing machines, bathroom sinks, bathroom tub, etc.
Generally, greywater or sullage is completely free of fecal materials (faeces) because it is independent from all toilet activities. However, greywater is not clean for direct use because it usually contains food particles, dirt, oil from dishes, hair, etc.
In this scenario, Anna makes arrangements to reuse waste water that has been used in sinks and showers. Greywater is a term which refers to the waste water that Anna reuses to conserve resources.
Therefore, Anna reuses greywater to conserve resources.
Information or signals entered into a computer system is

Like data logs. Sometimes people make these logs to keep tabs on other people or to get important information put down somewhere that way it is saved and can be looked back upon later. Anytime someone makes an action on the computer, it makes a TMP file representing a log of what you want it to do before the computer quickly get's rid of the file.

A continuously variable transmission:
A) Can use the same fluid as any other automatic transmission
B) Needs transmission fluid exchanges much more frequently
C) Requires a transmission fluid specially formulated for CVT needs
D) Is the same as a step-gear transmission
Answer:
A continuously variable transmission (CVT) is an automatic transmission that can change seamlessly through a continuous range of gear ratios. This contrasts with other transmissions that provide a limited number of gear ratios in fixed steps. The flexibility of a CVT with suitable control may allow the engine to operate at a constant RPM while the vehicle moves at varying speeds.that means the ans is A.
A continuously variable transmission requires a transmission fluid specially formulated for CVT needs. The correct option is C.
What is continuously variable transmission?Because a CVT operates differently than a traditional step-gear transmission, it requires a unique type of transmission fluid that is formulated to meet its specific performance requirements.
CVT fluid helps to maintain the proper frictional properties of the transmission's belts and pulleys, as well as providing cooling and lubrication for the transmission components.
While CVT fluid should be changed at the manufacturer's recommended intervals, it does not have to be changed as frequently as the fluid in a traditional automatic transmission.
Thus, the correct option is C.

The BARO sensor informs the PCM about changes in weather and ____________________.
A.road conditions
B.altitude
C.driving habits
D.day or night
Answer: The BARO sensor informs the PCM about changes in weather and B.altitude
Explanation: The barometric sensor reads the barometric pressure (the density of the atmosphere according to altitude and weather conditions). The barometric pressure (BARO) sensor works in conjunction with the manifold absolute pressure (MAP) sensor to provide constant pressure difference information to the PCM. Barometric pressure is the size of air strain in the atmosphere, in particular the size of the load exerted by way of air molecules at a given point on this planet. The Manifold Absolute pressure sensor performs 'double obligation' as a barometric stress sensor as soon because the key's turned on. With the key became on (prior to the engine starting) there is no vacuum inside the engine applied to the MAP sensor therefore its sign to the ECM will become a BARO studying useful in determining air density.
What is inertia?
Please help!!
Answer:
Explanation:
This tendency to resist changes in their state of motion is described as inertia. Inertia: the resistance an object has to a change in its state of motion. Moving objects, so it was believed, would eventually stop moving; a force was necessary to keep an object moving.
Basically inertia is like something that drives you to do something. It comes in many forms, as stated in a book (the book was Four, of the Divergent series), someone can be tempted to do something because it is what they are used to doing (comfortable with really).

When lubricating parts that do not have a grease relief port, inject grease until
A. The boot splits
B. Grease begins to escape from the base of the boot
C. The boot swells slightly
D. The part won't hold any more
Answer:
C. The boot swells slightly
Explanation:
Friction can be defined as a force that opposes the motion of an object in relation to another.
This ultimately implies that, friction is the opposition to the relative motion of two objects in contact. Therefore, lubrication (lubricants) are used to prevent friction between moving parts.
Generally, grease relief port are created by manufacturers of mechanical parts so as to prevent over-lubrication.
However, when lubricating parts that do not have a grease relief port, inject grease until the boot swells slightly so as to maintain the seal at the ball joints.
