Since parallel lines never cross, then there can be no intersection; that is, for a system of equations that graphs as parallel lines, there can be no solution. This is called an "inconsistent" system of equations, and it has no solution.

2. C
That's right. If a system of equations has a solution, then their graphs intersect, and the point where they intersect is the solution because it's the point that satisfies each equation in the system.
Straight-line graphs with the same slope are parallel lines, and they never intersect, which is another way of saying they have no solution.

Construct a circle through points
X, Y, and Z
Answers
Answer:
Step-by-step explanation:
1st draw 3 circles where each center is on one of the points, and the other side , the drawing side of the compass is on another point.. the draw the circle ... do that for each point... there will be one point.. where all three cross some where in the middle.. put the point of your compass on that point.. and then put the drawing side on any one of the points... all 3 will now be on the circle.. draw it.. :)
The circle can be constructed through points X, Y, and Z by drawing a side on any one of the points.
What is a circle?It is described as a set of points, where each point is at the same distance from a fixed point (called the center of a circle)
As we can see in the picture.
The construction of a circle through three points can be done:
First, draw three circles with each center on one of the points and the drawing side of the compass on another point.
There will be one place where all three intersect somewhere in the middle, but the point of your compass should be on that point, and then put the drawing side on any one of the points.
Thus, the circle can be constructed through points X, Y, and Z by drawing a side on any one of the points.

Answer:
[tex]x + 2x + 24 = 180 \\ 3x = 180 - 24 \\ 3x = 156 \\ x = 52[/tex]
Steps:
180 = x + (2x + 24)
180 = x + 2x + 24
180 = 3x + 24
180 - 24 = 3x
156 = 3x

Area of the unshaded region = 95/360 * 3.14 * (5*√2)^2
Area of the unshaded region = 95/360 * 3.14 * 50
Area of the unshaded region = 41.43
Area of the entire circle = pi r^2
Area of the entire circle = 3.14 * (5√2)^2
Area of the entire circle = 157
Area of the shaded part = The whole circle's area - the unshaded part
Area of the shaded part = 157 - 41.42
Area of the shaded part = 115.57

Step-by-step explanation:
Given
A = (-2,4)
C = (4,7)
If B is located on AC such that AB to AC is 1:3
X coordinate of B;
X = ax1+bx2/a+b
X = 1(-2)+3(4)/1+3
X = -2+12/4
X = 10/4
X = 2.5
Y coordinate of B;
Y = ay1+by2/a+b
Y = 1(4)+3(7)/1+3
Y = 4+21/4
Y = 25/4
Y = 6.25
hence the coordinate of B is at (2.5, 6.25)

A game that costs $72 is on sale for 20% off. It has a sales tax rate of 7.5% 20 on the sale price. What is the final cost of the game?
Answers
Answer:
$61.92
Step-by-step explanation:
Lets start by applying the sale(discount) on the game. 20% off is synonymous with having 80% of something(the remaining part), so we can multiply 72*.8 in order to get $57.6
Now lets apply sales tax. A simple way to calculate total price when a tax or increase is present is by adding 100% to the % and multiplying. In this case, we would have [tex]1.075 * 57.6 = $61.92[/tex]

this is tricky b/c they are making the two triangles of different scales but of the same angles.... soooo one is just a bigger copy of the other....
Step-by-step explanation:
Since this is a relation of the two side of each.. we can say the following...
[tex]\frac{6}{9}[/tex] = [tex]\frac{4}{x}[/tex] where X = side LA soooo solve for X
x * [tex]\frac{6}{9}[/tex] = 4 (move the X , to the other side of the '=' sign
x = 4 * [tex]\frac{9}{6}[/tex] ( yes.. we want to invert the fraction to move it to the other side )
x = [tex]\frac{36}{6}[/tex]
x = 6
so side LA is 6 :)

Find the area of the shaded region. Round your answer to the nearest tenth if needed.
Answers
Answer:
140 inches
Step-by-step explanation:
Find the area of the square.
4 + 10 = 14 (Length)
11 + 4 = 15 (Breadth/Width)
Area = 14 x 15 = 210 inches
Find the area of the 2 unshaded squares in the square.
Area of square at the top = 4 x 4 = 16 inches
Area of square at the bottom = 6 x 9 = 54 inches
Add the 2 squares of the area together.
16 + 54 = 70 inches
Now deduct the area of the huge box by the area of the 2 unshaded squares.
210 - 70 = 140 inches

Nancy is checking to determine if the expressions x + 4 + x and 6 + 2 x minus 2 are equivalent. When x = 3, she correctly finds that both expressions have a value of 10. When x = 5, she correctly evaluates the first expression to find that x + 4 + x =14.
What is the value of the second expression when x = 5, and are the two expressions equivalent?
The value of the second expression is 8, so the expressions are not equivalent.
The value of the second expression is 14, so the expressions are equivalent.
The value of the second expression is 16, so the expressions are equivalent.
The value of the second expression is 18, so the expressions are not equivalent.
