Which of the following describes the graph of the
equation 3y = 6x +12?
a line with slope 2 and y-intercept (0,4)
a line with slope 2 and y-intercept (0, 12)
a line with slope 6 and y-intercept (0,4)
a line with slope 6 and y-intercept (0, 12)
First write the equation in the form y=mx+c
[tex] \frac{3y}{3} = \frac{6x}{3} + \frac{12}{3} \\ y = 2x + 4[/tex]
YOU CAN SEE THAT NOW THE SLOPE OF THE LINE IS 2 TO GET THW Y INTERCEPT WE KNOW THAT AT THE Y-AXIS x=0
PLUG IN 0 IN THE PLACE OF X TO GET Y IN THE EQUATION OF THE LINE.
[tex]y = 2(0) + 4 \\ y = 4[/tex]
THE Y-INTERCEPT IS (0,4)
THEREFORE THE LINE HAS A SLOPE 2 AND A Y INTERCEPT (0,4)

The second angle of a triangle measures three times as large as the first. If the third angle measures 55 degrees more than the first, find the measure of all three angles. ( recall that the sum of the angles of a triangle add to 180 degrees )
Taking x as the measure of the first triangle, we know that the second one measures three times as x:
[tex]3x[/tex]And the third one measures 55 degrees more than the first:
[tex]x+55[/tex]We know that the sum of the angles of a triangle is 180, use this information to find x:
[tex]\begin{gathered} x+3x+(x+55)=180 \\ 5x+55=180 \\ 5x=180-55 \\ x=\frac{125}{5} \\ x=25 \end{gathered}[/tex]It means that the first angle measures 25°. Use this value to find the second and third angles:
[tex]\begin{gathered} 3x=3\cdot25=75 \\ x+55=25+55=80 \end{gathered}[/tex]It means that the second angle measures 75° and the third one measures 80°.

Evaluate the expression (c^2) + (d^3) for c = 3 and d = 3
ANSWER
36
EXPLANATION
We want to evaluate the expression for when c = 3 and d = 3.
The expression given is:
[tex]c^2+d^3[/tex]To do this, we will simply replace the values of c and d with the values given:
[tex]\begin{gathered} 3^2+3^3 \\ =\text{ 9 + 27} \\ =\text{ 36} \end{gathered}[/tex]That is the answer.
WXYZ is a rectangle if M angle w x y equals 6X squared - 6 find a
Given the rectangle WXYZ, the angle m∠WXY=6a²-6
The given angle is a corner angle, and as you might remember all corner angles of a rectangle are right angles, so we can say that the given expression equals 90 degrees:
[tex]6a^2-6=90[/tex]From this expression you can calculate the value of a.
First step is to add 6 to both sides of the equation so that the a-related term stays alone in the left side of the equation and all costants are in the other side:
[tex]\begin{gathered} 6a^2-6+6=90+6 \\ 6a^2=96 \end{gathered}[/tex]Next divide both sides by 6:
[tex]\begin{gathered} \frac{6a^2}{6}=\frac{96}{6} \\ a^2=16 \end{gathered}[/tex]And calculate the square to both sides of the variable to reach the possible value of a:
[tex]\begin{gathered} \sqrt[]{a^2}=\sqrt[]{16} \\ a=4 \end{gathered}[/tex]Now, just because the result is positiv, that does not mean that is the only possible value for a, if you square -4 you can also get 16 as a result, so a can be negative 4 or positive 4:
a=±4
The correct option is B.

How to illustrate the information?It should be noted that the weights of the chocolate in Hershey Kisses are normally distributed with a mean of 4.5338 g and a standard deviation of 0.1039 g.
In this case, for a normal distribution, mean = median = mode. The median is 4.5338
The mode is also 4.5338.
The variance will be the square of the standard deviation. This will be:
= (0.1039)²
= 0.0108.

What is the volume of a prism that is 10 mi tall with a right triangle for a base with side lengths 6 mi, 8 mi, and 10 mi ?
The expression for the volume of the Prism is 1/3(Base area x Height)
In the given prism
Height = 10 mi
Base is in the shape of right angle triangle
Area of right angle triangle = 1/2 x Base x Height
Area of right angle triangle = 1/2 x 8 x 6
ARea of right angle triangle = 24
Area of base of the prism = 24mi².
Volume of the prism = 1/3 (Base area x Height)
Volume of the prism = 1/3 (24 x 10)
Volume of the prism = 1/3(240)
Volume of the prism = 80mi³.
The volume of prism is 80 mi³.

Enter the answers in the boxes to complete the coordinate proof.
P is the midpoint of DE. Therefore, the coordinates of P are ( answer, b ).
Q is the midpoint of DF. Therefore, the coordinates of Q are (3a, answer).
R is the midpoint of EF. Therefore, the coordinates or R are ( answer, answer)
The length of PR is √ a^2+b^2. The length of QR is √ a^2 +b^2.
Comparing the expressions for the lengths of PR and QR shows that the lengths are equal. therefore, △PQR is isosceles
The area of triangle DEF = 4 ( area of triangle QRP) which is determined that by comparing the expression for the lengths of PR and QR.
What are congruent triangles?Two triangles are said to be congruent if their corresponding sides and angles are equal.
According to the data provided,
Triangle ΔDEF is an isosceles triangle having DE, EF, and FD sides.
Since DE = EF and P,R, and Q are the midpoints of the sides DF, EF, and DE,
We know from isosceles triangle theorems that the area of a triangle formed by uniting the midpoints of two isosceles triangles is one-fourth the area of the isosceles triangle.
As evidence, consider the following:
Because point Q is the halfway of DE, its coordinates are (a, b). (Because the midpoint of a line segment always has coordinates that are half the total of the coordinates of the end points.)
Because point R is the midpoint of FE, its coordinates are (3a,b).
The length of the base, DF, in triangle DEF is 4a and the height is 2b. As a result, its area is 4ab. (Because the area of a triangle equals 1/2 its base × height.)
The length of the base, QR, of the triangle QRP is 2a, while the height is b.
As a result, its area is ab.
Therefore, the area of triangle DEF is four times that of triangle QRP.

The science club members are using transformations on coordinate grids to track the movement of constellations in the sky. Choose the left side of the constellation depicted by the line passing through (1,7) and (2.5,1), and find the linear functions that correspond to the series of motions of the side given below.
1) Shift the side down 5 units.
2) Vertically stretch the result of the shift by 3.
3) Shift the result of the stretch 2 units to the left.
The linear function passing through points (1,7) and (2.5, 1) is given by:
y = -4x + 11.
What is a linear equation?
It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.
y = mx + b
In which the coefficients are described as follows:
The coefficient m is the slope of the function, representing the rate of change of the function.The coefficient b is the y-intercept of the function, representing the value of y when the function crosses the y-axis(x = 0).For this problem, the two points that form the function are given as follows:
(1,7) and (2.5, 1).
The slope is given by change in y divided by change in x, hence it is given by:
m = (1 - 7)/(2.5 - 1) = -4.
Then:
y = -4x + b.
When x = 1, y = 7, hence we can find the intercept b of the function as follows:
7 = -4(1) + b
b = 7 + 4
b = 11.
Hence the equation is:
y = -4x + 11.

Differentiation from First Principles is a formal method for determining a tangent's gradient.
What is meant by differentiation?Finding a function's derivative is the process of differentiation. It is also the process of determining how quickly a function changes in relation to its variables.
According to the Sum rule, a sum of functions' derivatives equals the sum of those functions' derivatives. The derivative of two different functions is the difference of their derivatives, according to the Difference rule.
Differentiation from First Principles is a formal method for determining a tangent's gradient. The straight line connecting any two locations on the curve that are fairly near to one another will have a gradient that is similar to that of the tangent at those places.
s(t) = ∫vdt = ∫sin(πt)dt = (-cos(πt))/π + c

(-cos(3π))/π + c = 0
1/π + c = c
c = -1/π

Gavin rides motocross in competition. A competition-level bicycle costs $1,800. He can borrow themoney from the bank at 3.596 interest for two years. By the end of the loan, how much money willGavin end up paying the bank?
The simple interest formula is:
[tex]I=Prt\text{ }[/tex]where P is the principal, r is the interest rate and t is the time.
In this case the principal is $1800, the interest rate is 0.035 (in decimal form) and t is 2. then the interest he pays is:
[tex]I=(1800)(0.035)(2)=126[/tex]Therefore in total he will pay $1926
