Reggie is asked to graph this system of equations:
3x + 4y = 8
y-5x = 2
How many times will the lines intersect?
A. There is no way to tell without graphing the lines first.
B. The lines will intersect infinitely many times, because they are
identical.
C. The lines will not intersect, because this system has no solutions.
D. The lines will intersect once, because this system has one
solution.
We will solve by graphing this system.
According to the graph bellow, the answer is D. The lines will intersect once, because this system has one solution.
Answer: D. The lines will intersect once, because this system has one solution

The linear equation is given as y = 2x + 4
What is an Equation of a line?The equation of a line is expressed as y = mx + b where m is the slope and b is the y-intercept
And y - y₁ = m ( x - x₁ )
y = y-coordinate of second point
y₁ = y-coordinate of point one
m = slope
x = x-coordinate of second point
x₁ = x-coordinate of point one
The slope m = ( y₂ - y₁ ) / ( x₂ - x₁ )
Given data ,
Let the equation be represented as A
Now , the value of A is
Let the x values be = { -4 , -2 , 0 , 2 }
Let the y values be = { -4 , 0 , 4 , 8 }
The slope of the line is m = ( y₂ - y₁ ) / ( x₂ - x₁ )
Substituting the values in the equation , we get
Slope m = ( 0 - ( -4 ) / ( -2 - ( - 4 ) )
On simplifying the equation , we get
Slope m = 4/2 = 2
Now , the equation of line is
y - y₁ = m ( x - x₁ )
Substituting the values in the equation , we get
y - 0 = 2 ( x - ( -2 ) )
On simplifying the equation , we get
y = 2x + 4
Hence , the linear equation is y = 2x + 4

Answer:
204 R45
Step-by-step explanation:
Answer: The answer will be 205 R2
Step-by-step explanation:
I know this because the steps to dividing are:
D - Divide
M - Multiply
S - Subtract
B - base(total)
If you do all of those steps then you'll get 205 R2
R = remainder(left overs)
So, the answer will be 205 R2
how do you find an equation for a line with a slope of 2/3 passing through (1,-4)
Answer:
The standard general equation for a straight line is:
y = mx + C. You said the slope of line is 2/3. m is always the slope in this context. So with the numerical value slope we have the line
Y = 2/3 X + C. You also said the line passes through the point (1, -4) that is the X value is 1 and the y value is -4. Substitute these value into the linear equation to find C, as follows
-4 = 2/3 + c. and so C = - 4 - 2/3 = -14/3 and so the equation of line is :
y = 2x/3 + 14/3 or if you like 3y = 2x + 14
It is important to remember that the convention of the bracketted numbers e.g. (1,-4) or ( 1, -4, z), say is that the first number in the brackets indicates the X value, the second the y value and the third, the z value in the case of 3 D coordinates.

Given :
Vanessa bought a 30 pound bag of rice she cooked 7.5 pounds of the rice she stores the rest of the rice in 4.5 pound portions.
To Find :
The maximum number of portions she stored.
Solution :
Let, number of portions she stored is n.
Amount of rice left, A = 30 - 7.5 = 22.5 pounds.
Now, number of portions of 4.5 pounds she stored :
[tex]n = \dfrac{22.5}{4.5}\\\\n = 5[/tex]
Therefore, maximum number of portions she stored is 5.
Hence, this is the required solution.
Why does sin54°≈0.809≈cos36° in a right triangle?
A
54° and 36° are complementary angles in the same right triangle. sin54° is the ratio of the opposite leg and the hypotenuse and cos36° is the ratio of the adjacent leg and the hypotenuse. In this triangle, the opposite leg of 54° and the adjacent leg of 36° are the same leg in the triangle.
B
54° and 36° are complementary angles in the same right triangle. sin54° is the ratio of the adjacent leg and the hypotenuse and cos36° is the ratio of the opposite leg and the hypotenuse. In this triangle, the adjacent leg of 54° and the opposite leg of 36° are the same leg in the triangle.
C
54° and 36° are supplementary in the same right triangle. sin54° is the ratio of the opposite leg and the hypotenuse and cos36° is the ratio of the adjacent leg and the hypotenuse. In this triangle, the opposite leg of 54° and adjacent leg of 36° are the same leg in the triangle.
D
54° and 36° are supplementary in the same right triangle. sin54° is the ratio of the adjacent leg and the hypotenuse and cos36° is the ratio of the opposite leg and the hypotenuse. In this triangle, the adjacent leg of 54° and opposite leg of 36° are the same leg in the triangle.

A
54° and 36° are complementary angles in the same right triangle. sin54° is the ratio of the opposite leg and the hypotenuse and cos36° is the ratio of the adjacent leg and the hypotenuse. In this triangle, the opposite leg of 54° and the adjacent leg of 36° are the same leg in the triangle.
Step-by-step explanation:
The answer explains itself.
The sum of angles in a triangle is 180°. When one of the angles is 90°, the sum of the other two angles is also 90°. That means those two acute angles are complementary (not supplementary).
The mnemonic SOH CAH TOA reminds you that ...
Sin = Opposite/Hypotenuse
Cos = Adjacent/Hypotenuse
