Answer:it’s 4 units to the left
Step-by-step explanation: The point (4,3) reflected the x-axis,
=> The x remains the same, the y flips over the x-axis to be negative
(4,3) ==>> (4,-3)
The point (-3,-8) is reflected in the y-axis.
=> The y remains the same, the x flips over the y axis to be negative
(-3,-8)==>>(3,-8)
The point (2,4) is reflected in the line x = -3.
=> The x remains the same, the y flips over the x= -3 line.
Instead of reflecting over the x-axis (or the x = 0) line
and just being +4 or 4 above the x-axis to -4 or 4 below the x-axis-axis-axis
you have +4 being 7 above the x= -3 line so you need
7 below the x= -3 line or -10 SO
(2,4)==>>(2,-10)
The point (a, b) is reflected in the line y = x
Consider that the line x=y is a 45-degree diagonal.
Imagine a point on the 45-degree at +3 i.e. (3,0)
Imagine a line perpendicular to x=y from the point (3,0)
(sorry there is no way to draw on here - try drawing it)
The line would hit the x-axis-axis at (0,3)
So you can see the x becomes y and y become x.
(a,b)==>>(b,a)
For
ΔXYZ is defined by its vertices X(1,3), Y(-3,5), and Z(0, -5).
ΔXYZ is reflected in the y-axis.
So for each of the 3 points X, Y, and Z reflect about
the y-axis the same way in the second example above
and you will have the 3 new points X’, Y', and Z’
The translation T: (x, y) → (x -2, y + 4) maps the point (2, -3) to
The translation T: (x, y) → (x + 3, y - 2) maps the point (-4, -3) to
What you need to do here is just plug the values for X and Y into the translation.
e.g. for T: (x, y) → (x -2, y + 4) plug (2,-3) of x=2 y=-3 into (x -2, y + 4) and get the new values.

Which graph represents this system?
2 x minus 5 y = negative 5. y = two-fifths x + 1.
A) On a coordinate plane, 2 lines go through points (negative 5, negative 1) and (0, 1).
B) On a coordinate plane, a line goes through (0, 1) and (5, 3) and another goes through (0, negative 5) and (5, negative 3).
C) On a coordinate plane, a line goes through (0, 1) and (5, 3) and another goes through (0, 1) and (5, negative 1).
D) On a coordinate plane, a line goes through (0, 1) and (negative 5, negative 1) and another goes through (negative 5, negative 3) and (0, negative 5).
Answer:
Option A.
Step-by-step explanation:
When x = - 5, y = - 1,
lhs of (1) = - 10 + 5 = - 5
lhs of (2) = - 1 + 2 = 1
When x = 0, y = 1,
lhs of (1) = 0 - 5 = - 5
lhs of (2) = 1 - 0 = 1
Please help! Two functions are shown in the table. Which statement is true about the functions shown in the table? Show work.
The true statement about the function in the table is that slope of m(x) is negative while slope of n(x) is positive
How to find the equation of the values as in the tableThe equation of line in slope intercept form is written as
y = mx + c where m = slope and the y intercept is c
from the table the simultaneous equation is derived and solved as follows
-5/2 = 2m + c
1/2 = 0 + c
hence c = 1/2, solving for m gives
-5/2 = 2m + 1/2
-5/2 - 1/2 = 2m
2m = -3
m = -3/2
hence the slope is negative
for the second the values
1 = 2m + c
-1/3 = 0 + c
c = -1/3
solving for m knowing that c = -1/3
1 = 2m + (-1/3)
1 + 1/3 = 2m
4/3 = 2m
m = 2/3
hence the slope is positive

Find the distance between the points (6.6,7.9) and (6.6, 4.7).
To find the distance between the points (6.6,7.9) and (6.6,4.7), we can use the distance formula:
distance = √((x2 - x1)^2 + (y2 - y1)^2)
Plugging in the coordinates of the two points, we get:
distance = √((6.6 - 6.6)^2 + (4.7 - 7.9)^2)
Simplifying this expression gives us:
distance = √((0)^2 + (-3.2)^2)
Which simplifies to:
distance = √(10.24)
Finally, taking the square root of both sides gives us:
distance = 3.2
So, the distance between the points (6.6,7.9) and (6.6,4.7) is approximately 3.2.

Drag the tiles to the correct boxes to complete the pairs.
Match the pairs of coordinates with the distances between them.
The pairs of coordinates should be matched with the distances between them should be matched as follows;
Pairs Distance
(4, 2) and (1, -2) → 5 units.
(-8, 7) and (2, -3) → √200 units.
(9, 1) and (1, 9) → √128 units.
(-2, -6) and (-8, 2) → 10 units.
How to calculate the distance on coordinates?Mathematically, the distance between two (2) points that are on a coordinate plane can be calculated by using this formula:
Distance = √[(x₂ - x₁)² + (y₂ - y₁)²]
For the ordered pairs (4, 2) and (1, -2), we have;
Distance = √[(x₂ - x₁)² + (y₂ - y₁)²]
Distance = √[(1 - 4)² + (-2 - 2)²]
Distance = √[(-3)² + (-4)²]
Distance = √(9 + 16)
Distance = √25
Distance = 5 units.
For the ordered pairs or points (-8, 7) and (2, -3), we have;
Distance = √[(x₂ - x₁)² + (y₂ - y₁)²]
Distance = √[(2 + 8)² + (-3 - 7)²]
Distance = √[(10)² + (-10)²]
Distance = √(100 + 100)
Distance = √200 units.
For the ordered pairs or points (9, 1) and (1, 9), we have;
Distance = √[(x₂ - x₁)² + (y₂ - y₁)²]
Distance = √[(1 - 9)² + (9 - 1)²]
Distance = √[(-8)² + (8)²]
Distance = √(64 + 64)
Distance = √128 units.
For the ordered pairs or points (-2, -6) and (-8, 2), we have;
Distance = √[(x₂ - x₁)² + (y₂ - y₁)²]
Distance = √[(-8 + 2)² + (2 + 6)²]
Distance = √[(-6)² + (8)²]
Distance = √(36 + 64)
Distance = √100
Distance = 10 units.

What are some possible solutions for the following inequality?
-3x+5x-2>-4x+1
Answer:
Any value greater than 0.5.
Step-by-step explanation:
First, set the inequality to an equation and solve for x:
[tex]-3x+5x-2=-4x+1\\2x-2=-4x+1\\2x-2+4x=-4x+1+4x\\6x-2=1\\6x-2+2=1+2\\6x=3\\(\frac{1}{6})6x=3(\frac{1}{6})\\x=\frac{1}{2}[/tex]
This is the value at which the inequality equals 0. To test the inequality and determine whether x is greater or less than [tex]\frac{1}{2}[/tex], choose any value of x that is easy to work with on either side of [tex]\frac{1}{2}[/tex]:
For x=0:
-3(0)+5(0)>-4(0)+1
0>1 This is not a true statement. Therefore, x is not less than [tex]\frac{1}{2}[/tex].
For x=1:
-3(1)+5(1)>-4(1)+1
-3+5>-4+1
2>-3 This is a true statement. Therefore, x is any value greater than [tex]\frac{1}{2}[/tex].

Answer:
There are 16 nickels and 15 dimes.
Step-by-step explanation:
let x = number of dimes
let y = number of nickels
x + y = 31
.1x + .05y = 2.30
Solve x + y = 31 for x
x = 31 - y
multiple the second equation by 100 to eliminate the decimals.
10x + 5y = 230 Substitute 31 - y for x
10(31-y) + 5y = 230 Distribute the 10
310 -10y + 5y = 230 Combine like terms
310 -5y = 230 Subtract 310 from both sides
-5y = -80 Divide both sides by -5
y = 16
There are 16 nickels.
Plug in 16 for y to solve for x
x + y = 31
x + 16 = 31 Subtract 16 from both sides
x = 15
There are 15 times.
Check:
10x + 5y = 230
10(15) + 5(16) = 230
150 + 80 = 230
230 = 230
Without doing any calculations, compare expression A to expression B. 56×250 (13×250)+(12×250) Choose the words to complete the comparison. Expression A is expression B.
Answer:
The distributive law of multiplication states that when a number is multiplied with the sum is equal to the number multiplied by each addend with the number and then sum of the both products.
by example a*(b+c)=(a*b) + (a*c)
Here the expression A is (5/6)*250
the expression B is ( 1/3 × 250 ) + ( 1/2 × 250 )
expression B is ( 1/3 × 250 ) + ( 1/2 × 250 )
=250*(1/3+1/2) applying distributive law of the multiplication
=250*((2+3)/6)
=250*(5/6)
=(5/6)*250
Therefore the expression A is equal to the expression B.

If you were to create a right triangle on the grid, what would the vertical and horizontal lengths be? Do these lengths match those you found in parts D and E of question 1?
-(Answer for D:)
The greater x-coordinate is 4. So, subtract the lesser x-coordinate, -2, from the greater x-coordinate, 4.
4 − (-2) = 6
Subtracting the lesser x-coordinate from the greater x-coordinate gives a difference of 6. So, 6 is the horizontal length.
-(Answer for E:)
The greater y-coordinate is 1. So, subtract the lesser y-coordinate, -1, from the greater y-coordinate, 1.
1 − (-1) = 2
Subtracting the lesser y-coordinate from the greater y-coordinate gives a difference of 2. So, 2 is the vertical length.
The vertical length is 2 units and Horizontal length is 6 units.

One boxcar of a model train measures 6 inches in length. The actual length of a boxcar is 606 inches (50.5 ft). What is the scale of the model?
To find the scale of the model train boxcar, we need to determine the ratio of the actual size of the boxcar to the size of the model. We can do this by dividing the actual size of the boxcar by the size of the model:
scale = actual size / model size
Plugging in the values from the problem, we get:
scale = 606 inches / 6 inches
Simplifying this expression gives us:
scale = 101
So, the scale of the model train boxcar is 101. This means that for every 1 inch of the model, there are 101 inches in the actual size.
