Answer:
See proof below
Step-by-step explanation:
Given the expression 2/4-x = 10/4+x
Cross multiply
10(4-x) = 2(4+x)
10(4) - 10x = 2(4)+ 2x
40 - 10x = 8 + 2x
-10x - 2x = 8 - 40
-12x = -32
Multiply both sides by -1
-1(-12x) = -1(-32)
12x = 32
This shows the required expression

Answer: A: (6, 5)
Step-by-step explanation:
When graphing a system of equations, you can find the solution by finding where the graphs intersect. In this case, the graphs intersect at (6, 5).
To verify that this is indeed a solution to the system of equations, we can substitute (6, 5) into both of the given equations:
[tex]y = \frac{1}{2}x + 2[/tex]
[tex]5 = \frac{1}{2} * 6 + 2[/tex]
[tex]5 = 3 + 2[/tex]
[tex]5 = 5[/tex]
[tex]y = x - 1[/tex]
[tex]5 = 6 - 1[/tex]
[tex]5 = 5[/tex]
Since both equations hold true when plugging in the given coordinate (6, 5), we know that this is a solution to the system of equations.

Answer:
A=11,13,17,19 B=12,18 None=10,14,16,19 Both=15
Step-by-step explanation:
11,13,15,17,19 are all odd so they go in A
12,15,18 Are all multiples of 3 so they go in B
10,14,16,19 Are not classified so they go outside of the diagram but inside E
15 is odd and a multiple of 3 so put it in the center and not with A and B
Triangle PQR is shown. The triangle has a base of 4 in and a height a 2.5 in.
Which measurement is closest to the area of triangle PQR in square inches?
5 in2.
8 3/4in.2
6 1/2in.2
11in.2
Answer:
A
Step-by-step explanation:
Area = 1/2 * b * h
b = 4 in
h = 2.5 inches
Area = 1/2 * 4 * 2.5
Area = 2 * 2.5
Area = 5 in^2
what is the scale factor of the small triangle to the large triangle?
Answer:
I'm pretty sure it's 4.3?
Step-by-step explanation:
Because you divide the larger triangles side first because you are figuring out the scale factor of the small triangle to the larger triangle, not the other way around.
Sorry if i'm wrong
Answer:
first, find the area of the small triangle: 3 times 3 equals 9 divided by 2 equals 4.5.
second, find the area of the big triangle: 13 times 13 equals 169 divided by 2 equals 84.5.
Find difference: 84.5 minus 4.5 equals 80

Let's assume our class is truly representative of the population at large. (a) Calculate the probability of having three right handed people in a sample of 10. Do this using R. (b) repeat, but this time calculate the probability of 3 or less right handed people in a sample of 10.n=17 right handed= 15 left handed=2
Answer:
0.1171875;
0.171875
Step-by-step explanation:
It is either a person is right handed or left handed
P(right handed) = 1/2
Probability of having 3 right handed people in a sample of 10 ;
P(x =x) = nCx * p^x * (1 - p)^(n - x)
P(x = 3) = 10C3 * 0.5^3 * 0.5^7
P(x = 3) = 120 * 0.125 * 0.0078125
P(x = 3) = 0.1171875
Using R ;
P(x ≤ 3)
We can obtain these from R using ;
pbinom( r, n, p)
pbinom(3, 10, 0.5) = 0.171875

Answer:
z = 47 at (x, y) = (3, 8)
Step-by-step explanation:
In the attached graph, the inequalities are graphed as their opposites, so the feasible solution region is the white area of the graph. The dashed boundary lines are part of the feasible region. The vertex of the feasible region that is farthest from the origin is ...
(x, y) = (3, 8)
The value of z there is 5·3 +4·8 = 47.

16 + 4 + (42 - 3) = 20 + 39 =59Answer:
59
Step-by-step explanation:
16 + 4 + (42-3) = 59. Do parentheses first. (42-3) = 39. Which changes the equation to 16 + 4 + (39). 39 + 4 = 43. Then the equation changes to 16 + 43. These added together equal 59. Hope this helps!

How do you graph x+6y=0
Answer:
We need to put this equation into either form of a line, pererably, slope intercept form!
Step-by-step explanation:
To do this, out goal is to get y alone.
1. We subtract x on both sides.
2 We divide 6 on both sides.
3. Our answer is y= -x/6 ( negative x divided by 6)
4. The y-intecept value is when x is equal to zero, so plug in 0 for x and solve for y.
5. The y intercept is (0,0)
6. From (0,0) point, you go down -1 and move 1 to the right each time!
The graph will be a line with a slope of -1/6 that passes through the points (0,0), (6,-1), and (-6,1).
What is Graph?Graph is a mathematical representation of a network and it describes the relationship between lines and points.
To graph this equation, start by rearranging it to solve for y.
y = -x/6
Next, plot a few points to fill in the graph.
when x is 0,
y is 0.
When x is 6,
y is -1, and
when x is -6, y is 1.
Finally, connect the plotted points with a straight line.
The final graph will be a line with a slope of -1/6 that passes through the points (0,0), (6,-1), and (-6,1).
Hence, graph will be a line with a slope of -1/6 that passes through the points (0,0), (6,-1), and (-6,1).

What is quadrilateral?
It is defined as the four-sided polygon in geometry having four edges and four corners and two pairs of congruent sides.
We have:
In the diagram below, O is circumscribed about quadrilateral ABCD.
In a quadrilateral, the sum of the opposite angles is equal to 180 degree
5x + 75 = 180
