The graph shows a coordinate plane that goes from negative 8 to 8 in each direction. The graph also shows two lines that intersect at ( 2 , 3 ). That point is labeled "solution." That's right. When you have two or more linear equations, it is called a "system of linear equations". The solution to a system of linear equations consists of the - and -value that make BOTH equations true. Graphically, this appears as the point where the lines intersect. In this case, the solution is the ordered pair , as shown on the graph. If you are trying to decide whether a system of equations has a solution, would you rather have the equations or the graphs? Why?

To visualize the solution of a system of equations, a graph is ideal, as we can see whether the functions intersect or not.
What is a system of equations?A system of equations is when multiple variables are related, and equations are built to find the numeric values of each variable, according to the relations built in the context of the problem. The pair/tuple/... containing these values is called the solution of the system.
The equations that construct a system are functions, and the solution of a system is at the point of intersection of these functions. The intersection of two points is easier to visualize graphically then calculating, hence a graph is ideal, as we can see whether the functions intersect or not, while for the function we would have to calculate.

In triangle ABC, the segments drawn from the vertices intersect at point G. Segment FG measures 6 cm, and segment FC measures 18 cm. Which best explains whether point G can be the centroid? (are the answers given here right? cos I'm not quite sure)
Answers
A centroid divides each median in a ratio 2:1, in this case, the segment FC is the sum of the segments FG and GC:
[tex]FC=FG+GC[/tex]By solving for GC, we get:
[tex]GC=FC-FG=18-6=12[/tex]Then, the part of the median that goes from C to G has a length of 12 and the part that goes from the centroid to F has a length of 6, then we can express their ratio as 12:6, which is equivalent to 2:1.
Then the answer is:
Point G can be the centroid because 12:6 equals 2:1

Sketch a graph of 6 x + 4 y = 4
Answers
The graph of 6x + 4y = 4 can be sketched as shown in the image attached below.
How to Sketch the Graph of a Linear Equation?A linear equation can be expressed in standard form as Ax + By = C, where A, B, and C are integers. Also, it can be rewritten in slope-intercept form as y = mx + b, where b is the y-intercept and m is the slope of the equation.
In order to graph an equation, we can easily determine what the slope (m) and the y-intercept (m) of the graph would be when we rewrite the equation in slope-intercept form.
Given the equation in standard form as, 6x + 4y = 4, rewrite it in slope-intercept form:
6x + 4y = 4
4y = -6x + 4
y = -6x/4 + 4/4
y = -3/2x + 1
This means that the slope of the graph you'd sketch will be -3/2, and the line must intercept the y-axis at 1, because the y-intercept is 1.

Answers
Answer:
2.×10^-2 cm/h . . . . rounded to 2 dp
2.26×10^-2 cm/h . . . . rounded to 3 sf
Step-by-step explanation:
You want the difference in growth rates between 6.849×10^-4 cm per hour and 2.329×10^-2 cm per hour.
DifferenceThe difference of two numbers written in scientific notation requires that they have the same power-of-ten multiplier.
2.329×10^-2 - 6.849×10^-4
= 2.329×10^-2 - 0.06849×10^-2 = 2.26051×10^-2 = 0.0226051
RoundingThe question asks for the answer rounded to 2 decimal places and expressed in scientific notation.
0.0226051 ≈ 0.02 = 2×10^-2 . . . . cm per hour
It makes more sense to round the mantissa to 2 decimal places, meaning the value is rounded to 3 significant figures.
2.26051×10^-2 ≈ 2.26×10^-2 . . . . cm per hour
A flower bed is in the shape of a triangle with one side twice the length of the shortest side and the third
side is 13 feet more than the length of the shortest side. Find the dimensions if the perimeter is 157 feet.
Answers
Answer:
The triangle has sides of 36 feet, 72 feet, and 49 feet.
=====================================================
x = shortest side
2x = second side
x+13 = third side
The three sides add up to the perimeter of 157
(x)+(2x)+(x+13) = 157
4x+13 = 157
4x = 157-13
4x = 144
x = 144/4
x = 36
The shortest side is 36 feet.
The second side is 2x = 2*36 = 72 feet.
The third side is x+13 = 36+13 = 49 feet.
Check:
side1+side2+side3 = 36+72+49 = 157

The area of the desert is 25,000 square miles a scale drawing of the desert has a scale drawing 10 square inches. What is the scale of the map?
Answers
The scale of the map is 1 square inches = [tex]10^{13}[/tex] square inches.
Given that:-
Area of the desert = 25,000 square miles
Area of the desert in the map = 10 square inches
We have to find the scale of the map.
We know that,
1 mile = 63360 inches
Hence, conversion of square miles to square inches:-
1 mile * 1 mile = 63360 inches *63360 inches
1 square mile = 4,01,44,89,600 square inches
25,000 square miles = 40144893600*25000 = 10,03,62,24,00,00,000 square inches =[tex]10.036224 *10^{13}[/tex] ≈ [tex]10*10^{13}[/tex] square inches.

The value of the length AB xcm = -3½ which is derived using the completing the square method, and satisfies the expression 2x² - 5x - 42 = 0.
Completing the square methodTo solve for the unknown value of a quadratic equation; say ax² + bx + c = 0:
First make the coefficient of x² one by dividing through by "a"Move the constant "c" to the right hand side of the equationDivide the coefficient of "x" by 2, square the result and add to both sides of the equation.The left hand side of the equation would have a complete square which will then be easier to solve for the value "x".From the derived quadratic equation, applying the method of completing the square as follows;
2x² - 5x - 42 = 0
divide through by 2
x² - (5/2)x - 21 = 0
add 21 to both sides
x² - (5/2)x = 21
divide the coefficient of x, square the result and add it to both sides
x² - (5/2)x + (5/4)(5/4) = 21 + (5/4)(5/4)
factor the left hand side of the equation
(x - 5/4)² = 21 + (25/16)
simplify the right hand side
(x - 5/4)² = 361/16
take the square root of both sides
x - 5/4 = (+ or -)(19/4)
then;
x = 5/4 + 19/4 or 5/4 - 19/4
x = 3 or x = -3½
The quadratic equation 2x² - 5x - 42 = 0 is true for the value of x = -3½.

We have the following quadratic Function in a graph:
Now, we solve one aspect at a time:
Zeros
Let's remember that the zeros or roots of the quadratic function are those values of x for which the expression is 0. Graphically, the roots correspond to the abscissae of the points where the parabola intersects the x-axis.
By looking at the graph we can identify these, which in this case it is:
[tex](-2,0)[/tex]Axis of symmetry
Recall that the graph of a quadratic function is a parabola. The axis of symmetry of a parabola is a vertical line that divides the parabola into two congruent halves. The axis of symmetry always passes through the vertex of the parabola.
By looking at the graph we can identify this, which in this case it is:
[tex]x=-2[/tex]Max or min
In mathematical analysis, the maxima and minima of a function, known collectively as extrema (the plural of extremum), are the largest and smallest value of the function, either within a given range or on the entire domain.
By looking at the graph we can identify this, which in this case it is:
[tex]y=0[/tex]Vertex
Remember that the vertex of a quadratic equation or parabola is the highest or lowest point of the graph corresponding to that function. The vertex lies in the plane of symmetry of the parabola; whatever happens to the left of this point will be an exact reflection of what happens to the right.

===========================================================
Explanation:
Define these two events
A = father born in Michigan
B = mother born in Michigan
The notation ~A and ~B represent the opposite of each defined event above.
According to the table
P(A) = 0.48
P(B) = 0.73
If A and B were independent, then P(A and B) = P(A)*P(B) = 0.48*0.73 = 0.3504 = 35.04% but this contradicts the 29% in the "father born in Michigan" column and "mother born in Michigan" row. The table states that P(A and B) = 0.29 should be the case instead of 0.3504.
Because of this contradiction, this means P(A and B) = P(A)*P(B) is false and therefore A and B are NOT independent
--------------------------------------
Another way to look at it:
P(A) = 0.48
P(A given B) = P(A and B)/P(B)
P(A given B) = 0.29/0.73
P(A given B) = 0.39726 approximately
If A and B were independent, then P(A) and P(A given B) would be the same value. However, they are not. This is another way to see why the events are NOT independent
Through similar calculations, P(B given A) = P(A and B)/P(A) = 0.29/0.48 = 0.6042 approximately which doesn't match with P(B) = 0.73; if A and B were independent then P(B) needs to be equal to P(B given A).
