Answers
Step-by-step explanation:
The parallel line will have an equation of the form
[tex]y = -\dfrac{1}{2}x + b[/tex]
We solve for b by plugging in the values of the point (3, -4):
[tex]-4 = -\dfrac{1}{2}(3) + b[/tex]
[tex]\Rightarrow -8 = -3 + 2b[/tex]
Solving for b, we get
[tex]b = -\dfrac{5}{2}[/tex]
Therefore, the equation of the line parallel to 2x + 4y = 10 is
[tex]y = -\dfrac{1}{2}x -\dfrac{5}{2}[/tex]
In standard form we can write
[tex]x + 2y = -5[/tex] or [tex]2x + 4y = -10[/tex]

You are a mechanic who is measuring the valve clearance on a motorcycle engine. The current clearance for one of the valves is 0.30 millimeter (mm). The clearance should be at least 0.18 mm and no more than 0.22 mm. The valve clearance is set by using a spacer that reduces the distance between the cam and the valve by the size of the spacer. Spacers are available in 0.04 mm increments, and the spacer currently in the motorcycle engine is 2.84 mm. Which of the following size spacers, in millimeters, should you use to achieve a correct valve clearance?
Answers
The 0.2 mm spacers will be utilized in order to achieve the correct valve clearance.
What is the valve clearance of a motorcycle?On motorcycle and automobile engines, valve clearances essentially refer to the gap or distance between the top of the valve stem and the camshaft that controls it.
The exhaust valves in an automobile engine release the burned gases, while the intake valves permit air and fuel into the cylinder.
Given that:
The current clearance = 0.3 mmThe clearance range is between = 0.18 mm - 0.22 mmThe available spacer = 0.04 mm incrementsThe current spacer is = 2.84 mmThe difference in between the current and clearance range is:
0.3 mm - 0.18 mm = 0.12 mm0.3 mm - 0.22 mm =0.08 mmHowever, for clearance to be positioned within 0.18 mm - 0.22 mm. The required spacers to be used are 0.04 mm, and 0.08 mm in conjunction with:
Clearance 0.3 = 3.14Clearance 0.18 = 3.02Clearance 0.22 = 3.06The mean value = 3.04
Therefore, for us to approach and get to the value of 3.02, the required spacers to be that must be added are:
2.84+0.04 2.882.84+0.08 2.922.84+0.12 2.962.84+0.16 3.002.84+0.2 3.04Therefore, we can conclude that the 0.2 mm spacers will be utilized in order to achieve the correct valve clearance.

A rectangular swimming pool with dimensions 12 meters by 18 meters is surrounded by a pavement of uniform width x meters. Find the area of the pavement, A, as a function of x.
Answers
9514 1404 393
Answer:
A = 4x² +60x
Step-by-step explanation:
The area of walkway along each of the sides is the product of side length and walk width x. The total for the four sides is ...
12x + 18x + 12x + 18x = 2x(12 +18) = 60x
There is a square of walkway at each corner whose dimensions are x by x, so the corner area is ...
4·x²
Then the total walkway area is ...

plate. How much pie is left over in total?
Answers
Answer:
3/3
Step-by-step explanation:
there are 3 plates and 1/3 on each plate is 3
1/3+1/3+1/3= 3/3
An entity can be divided in fractions or ratios. The total number of pie left over on N plates is [tex]\frac 13N[/tex]
Given that:
[tex]k = \frac13[/tex] --- the fraction left over
The total number of pie left over is
[tex]Total = \frac{1}{3} \times N[/tex]
Where N is the number of plates
So:
[tex]Total = \frac{1}{3} N[/tex]
For instance
If N is 6, the number of pie will be 2: i.e.
[tex]Total = \frac{1}{3} \times 6 = 2[/tex]
If N is 12, the number of pie will be 4: i.e.
[tex]Total = \frac{1}{3} \times 12 = 4[/tex]

Answers
The inverse of the function y = 9x -4 is obtained by a reflection in the line at ( y = x ). Hence Option D is correct.
What is the reflection of a line?Each point of the original figure (the pre-image) has an image that is the same distance from the reflection line as the original point but is on the other side of the line. This transformation is known as a reflection over the line.
The inverse relation for y= 9x -4 will be calculated by putting the value of x equal to y or replacing x by y and y by x in the equation.
