How to read linear equations?
To read a linear equation, first, identify the constants and the variable, then determine the coefficient of the variable.
A linear equation is an equation that contains two variables and can be written in the form of ax + b = 0, where 'a' and 'b' are constants and 'x' is the variable. This coefficient will indicate how the variable is related to the constants. Then, solve the equation by isolating the variable to determine its value.
To read a linear equation, start by identifying the constants and the variable. The constant is the numerical value that is not connected to the variable. For example, in the equation "2x + 4 = 0", the constants are '2' and '4'. The variable is the letter that represents the values that can change. In this equation, the variable is 'x'.
Next, determine the coefficient of the variable. The coefficient is the numerical value in front of the variable. It represents how the variable is related to the constants. In this example, the coefficient of 'x' is '2'. This means that the value of 'x' will be twice as much as the constants.
Once the constants, variables, and coefficients have been identified, the equation can be solved.

Can 30 60 and 90 be the angles of a triangle?
No, the sum of the angles of a triangle must add up to 180 degrees. 30 + 60 + 90 = 180, so these angles cannot form a triangle.
The sum of the angles of a triangle must always add up to 180 degrees. To determine if a set of angles can form a triangle, add the angles together. If the sum is 180, the angles can form a triangle. In this case, 30 + 60 + 90 = 180, which does not equal 180. Therefore, these angles cannot form a triangle.

Please answer the question in the picture and show your work! I got tan= square root of 2 but I’m not sure if that’s right and if there’s more answers since it wants all values of tan. This is due tomorrow please help!
Answer:
tan(θ) is undefined.
Step-by-step explanation:
Recall that tan(θ) = sin(θ) / cos(θ). We are given that sin(θ) = -1. Hence:
[tex]\displaystyle \tan\theta=\frac{\sin\theta}{\cos\theta}=-\frac{1}{\cos\theta}[/tex]
Since 1 / cos(θ) = sec(θ):
[tex]\tan\theta=-\sec\theta[/tex]
We can square both sides:
[tex]\tan^2\theta=\sec^2\theta[/tex]
From the Pythagorean Identity:
[tex]\tan^2\theta+1=\sec^2\theta[/tex]
Substitute:
[tex]\tan^2\theta+1=\tan^2\theta[/tex]
So:
[tex]1\neq0[/tex]
Since we acquire an untrue statement, no solutions exist.
If needed, refer to the unit circle. Recall that sin(θ) only equals -1 when θ = 3π/2 (on the interval [0, 2π)). At 3π/2, cos(θ) = 0. Since tan(θ) = sin(θ) / cos(θ), tan(θ) is undefined whenever sin(θ) = -1 (or 1).

Step-by-step explanation:
The system Px + Qy = R has the solution (3,-1), where F, G, H, P, Q, and
Fx + Gy = H
R are nonzero real numbers.
Select all the systems that are also guaranteed to have the solution (3,-1)
a.) (P + F)x + (Q + G)Y = R + H
Fx + Gy = H
b.) (P + F)x + Qy = R + H
Fx + (G + Q)y = H
c.) Px + Qy = R
(3P + F)x + (3Q + G)y = 3H + R
d.) Px + Qy = R
(F - 2P)x +(G - 2Q)y = H - 2R
e.) Px + Qy = R
5Fx + 5Gy = 5H
*Please explain how you got your answer because I really don't understand this!
Answer:
The systems that are guaranteed have the solution (3, -1) are;
a.) (P + F)·x + (Q + G)·y = R + H
F·x + G·y = H
d.) P·x + Q·y = R
(F - 2·P)·x + (G - 2·Q)·y = H - 2·R
e) P·x + Q·y = R
5·F·x + 5·G·y = 5·H
Step-by-step explanation:
The given system of equation are;
a) P·x + Q·y = R...(1)
F·x + G·y = H...(2)
The solution of the system of equation = (3, -1)
Adding equation (1) to equation (2) gives;
P·x + Q·y + F·x + G·y = R + H
(P + F)·x + (Q + G)·y = R + H...(3)
Therefore, given that equation (3) is obtained from equation (1) and (2) by addition, equation (3), (P + F)·x + (Q + G)·y = R + H, we have;
The system of equation;
(P + F)·x + (Q + G)·y = R + H
F·x + G·y = H, derived from the given system of equation Is bound to have the same same solution (3, -1) as the given system of equation
d.) By multiplying equation (1) by 2, we have;
2 × (P·x + Q·y) = 2 × R
2·P·x + 2·Q·y = 2·R...(4)
Subtracting equation (4) from equation (2) gives;
F·x + G·y - (2·P·x + 2·Q·y) = H - 2·R
F·x - 2·P·x + G·y - 2·Q·y = H - 2·R
(F - 2·P)·x + (G - 2·Q)·y = H - 2·R
Therefore, for the following system, obtained from the original system, we have that the solution is (3, -1);
P·x + Q·y = R
(F - 2·P)·x + (G - 2·Q)·y = H - 2·R
e) For the system of equation, we have;
P·x + Q·y = R
5·F·x + 5·G·y = 5·H
The above system of equation is obtained from the original system by multiplying equation (2) by 5, therefore the solution of the system P·x + Q·y = R, 5·F·x + 5·G·y = 5·H is the same as the solution for the original system of equations (3, -1).
A right rectangular prism is sliced parallel to the base. What is the area of the resulting two-dimensional cross-section?
Answer:
The area of the resulting two-dimensional cross-section is 12 cm².
Step-by-step explanation:
The area of the cross-section of the right rectangular prism, parallel to the base, is given by the area of a rectangle:
[tex] A_{cs} = A_{r} = a*b [/tex]
Where:
[tex] A_{cs}[/tex]: is the area of the cross-section
[tex] A_{r} [/tex]: is the area of a rectangle
a: is the length of one side of the rectangle = 4 cm
b: is the length of the other side of the rectangle = 3 cm
Hence, the area of the cross-section is:
[tex] A_{cs} = a*b = 4 cm*3 cm = 12 cm^{2} [/tex]
Therefore, the area of the resulting two-dimensional cross-section is 12 cm².

What is the solution to the equation 9 W 4 )- 7w 5 3w 2?
The solution to w in the equation 9(w - 4) - 7w = 5(3w - 2) is w = -2.
Now, According to the question:
The given Equation:
9(w-4)-7w=5(3w-2)
To solve for w we first need to simplify our equation, removing any brackets and adding together similar terms. This gives us:
9(w-4)-7w=5(3w-2)
9w - 36 -7w = 15w - 10
2w - 36 = 15w - 10
Next, we subtract 2w from both sides to have all the variables on one side of our equation, then we add 10 to both sides to move the numerical values to one side.
2w - 36 = 15w - 10
2w -2w - 36 = 15w - 2w - 10
-36 = 13w - 10
-36 + 10 = 13w - 10 + 10
-26 = 13w
Finally, we divide both sides by 13 to find the value of w.

Slope formula says that y=mx+b.
In terms of words, it means that y is equivalent to slope times x plus the y-intercept.
Slope= rise/run. You rise 4 and run 5. (which is 4/5) However, the slope is negative so be careful with that.
We know the y intercept is 1 so replace that for b.
Put it together and you get y=-4/5x+1
