What is the general equation of a Straight line?
The general equation of a straight line is -
[y] = [m]x + [c]
where -
[m] → is slope of line which tells the unit rate of change of [y] with respect to [x].
[c] → is the y - intercept i.e. the point where the graph cuts the [y] axis.
The equation of a straight line can be also written to express proportional relationship as -
y = kx {k is constant}
We have a equation that represents a line as -
y = 4x + 2
We can graph the given equation as shown in the figure attached.
Therefore, the line y = 4x + 2 is graphed and attached with the answer.

Write the expression as either the sine, cosine, or tangent of a single angle.
sin 48° cos 15° - cos 48° sin 15°
A. cos 33°
B. cos 63°
C. sin 63°
D. sin 33°
Answer: Option 'D' is correct.
Step-by-step explanation:
Since we have given that
sin 48° cos 15° - cos 48° sin 15°
As we know that,
[tex]\sin A\cos B-\cos A\sin B=\sin(A-B)[/tex]
So, we get that
[tex]A=48\textdegree\\B=15\textdegree[/tex]
Now, put it in the above expression.
[tex]\sin (A-B)=\sin(48-15)=\sin 33\textdegree[/tex]
Hence, Option 'D' is correct.

Suppose one bottle of paint can cover 20 tiles. you have 348 tiles. how many bottles of paint do you need to buy to cover all 348 tiles? explain.
To cover 348 tiles when one bottle can cover 20 tiles, you divide 348 by 20 which equals 17.4, and then round up to 18 bottles since you can't buy a fraction of a bottle.
To determine how many bottles of paint are needed to cover 348 tiles when one bottle covers 20 tiles, you should divide the total number of tiles by the number of tiles that can be covered by one bottle. The calculation is as follows:
Divide 348 (the total number of tiles) by 20 (the number of tiles one bottle of paint can cover).
348 \/ 20 = 17.4
Since you can't buy a fraction of a bottle, you would need to round up to the next whole number. Therefore, you need 18 bottles of paint to cover all 348 tiles.

solve system by elimination
9x-3y=3
3x+8y=-17
Final answer:
The system of equations 9x - 3y = 3 and 3x + 8y = -17 is solved using elimination. By multiplying the second equation by 3 and subtracting the first from the resulting equation, y is eliminated and found to be -2. Substituting y into one of the original equations then gives x as -1/3.
Explanation:
Solving a System of Equations by Elimination
To solve the system by elimination, we aim to eliminate one of the variables by combining the equations. We have the equations 9x - 3y = 3 and 3x + 8y = -17. Let's multiply the second equation by 3 to align the coefficients of x.
After multiplication, our system looks like this:
9x - 3y = 3 (Equation 1)9x + 24y = -51 (Equation 2 multiplied by 3)
Now, subtract Equation 1 from Equation 2, which eliminates the x variable:
-3y - 24y = 3 - (-51)
-27y = 54
To find the value of y, divide both sides by -27:
y = -2
Now that we have y, we can substitute it back into one of the original equations to find x:
3x + 8(-2) = -17
3x - 16 = -17
3x = -1
x = -1/3
So the solution to the system is x = -1/3 and y = -2.
david's mass is 5kg less than john's,who in turn is 8kg lighter than paul.if their total mass is 197kg.how heavy is each person.
Answer:
Paul is 70 kg, John is 62 kg and David is 65 kg.
Step-by-step explanation:
Let x the mass for each person.
Paul = x
John is lighter than Paul, so John = x-8
David's mass is 5 kg less than John's, so David = x-5
Solution:
Make an equation.
x + (x-8) + (x-5) = 197
3x -13 = 197
3x = 197 + 13
3x= 210, then divide both side by 3, to get 70.
Do substitution to get a correct answer.
70+62+65= 197
197= 197

Round off or add zero to the following calculated answers to give a final answer with three significant figures: 0.00001258 L ...?
To round off or add zero to the calculated answer of 0.00001258 L and give a final answer with three significant figures, round up the last significant figure to 6.
Explanation:In order to round off or add zero to the calculated answer and give a final answer with three significant figures, follow these steps:
Start with the calculated answer: 0.00001258 LCount the number of significant figures in the given number, which is 5. Since we want to round to three significant figures, we need to round off or add zero to the answer to make it have three significant figures.In this case, the first three significant figures are 1, 2, and 5. The next digit is 8, which is greater than 5. Therefore, we round up the last significant figure to 6.The final answer, rounded off to three significant figures, is 0.0000126 L.To round off or add zero to the calculated answer to give a final answer with three significant figures, consider the following: For the value 0.00001258 L, the third significant figure is 5. Since the digit after the third significant figure (8) is greater than or equal to 5, we round up the third significant figure. Therefore, the final answer is 0.0000126 L.
Explanation:To round off or add zero to the calculated answer to give a final answer with three significant figures, consider the following:

11/12 - 5/8 Write your answer as a fraction in simplest form.
To subtract[tex]\(\frac{11}{12} - \frac{5}{8}\), find a common denominator (24), then subtract numerators: \(\frac{11}{12} - \frac{5}{8} = \frac{7}{24}\)[/tex] in simplest form.
To subtract the fractions [tex]\(\frac{11}{12} - \frac{5}{8}\[/tex]), we need to find a common denominator.
The least common multiple (LCM) of 12 and 8 is 24.
Now, rewrite both fractions with the denominator 24:
[tex]\[\frac{11}{12} \times \frac{2}{2} = \frac{22}{24}\]\[\frac{5}{8} \times \frac{3}{3} = \frac{15}{24}\][/tex]
Now, subtract:
[tex]\[\frac{22}{24} - \frac{15}{24} = \frac{22 - 15}{24} = \frac{7}{24}\]So, \(\frac{11}{12} - \frac{5}{8} = \frac{7}{24}\)[/tex]
