Answer:
x > -5
Step-by-step explanation:
(2/5)(x -1) < (3/5)(x +1) . . . . . given
2(x -1) < 3(x +1) . . . . . . . . . . .multiply by 5
2x -2 < 3x +3 . . . . . . . . . . . eliminate parentheses
-5 < x . . . . . . . . . . . . . . . . . . add -2x-3 to both sides
This matches the second answer choice: x > -5.

-18 (-3) answer explain
Answer:
54
Step-by-step explanation:
18(3) = 18+18+18 = 54
But remember that we have two negatives
When you multiply two negative numbers, they become positive, therefore your answer is 54

A pet store was selling 2 lizards for
$14.48. If they ended up selling 6
lizards, how much money would they
have earned?
Answer:
43.44
Step-by-step explanation:
If they are selling 2 lizards for 14.48 you would divide
14.48 by two which is 7.24.
This means the lizards are 7.24 each.
7.24x6 is 43.44
Answer:
$43.44
Step-by-step explanation:
If two lizards are worth $14.48, then you just need two multiply the cost by three.

How do I rewrite x + y = -3 in slope intercept form.
Answer:
y =-x-3
Step-by-step explanation:
slope intercept/ y-intercept form is y=mx+b
you have to isolate y here
x+y=-3 subtract x from both sides
y=-x-3
If a lizard can run 8 m across the water in 4 seconds, how
fast is he traveling?
Answer:
2 meters/second
Step-by-step explanation:
Equation for speed is:
s = d/t
Plug in the 8m for distance(d)
Plug in the 4 seconds for time(t)
So now you have s = 8m/4sec
This simplifies to s = 2 m/sec

∆ABC is translated 2 units down and 1 unit to the left. Then it is rotated 90° clockwise about the origin to form ∆A′B′C′. The coordinates of vertex A′ of ∆A′B′C′ are . The coordinates of vertex B′ of ∆A′B′C′ are . The coordinates of vertex C′ of ∆A′B′C′ are .
Answer:
A'(-2, 1), B'(1, 0), C'(-1, 0)
Step-by-step explanation:
Transformation is the movement of a point from its initial location to a new location. Types of transformation are rotation, reflection, dilation and translation.
If a point X(x, y) is translated a units right and b units down, the new location is X'(x + a, y + b) whereas if a point X(x, y) is translated a units left and b units up, the new location is X'(x - a, y - b).
If a point X(x, y) is rotated 90° clockwise about the origin, the new location is X'(y, -x)
From the image attached, ∆ABC is at A(0, 0), B(1,3) C(1, 1)
If ∆ABC is translated 2 units down and 1 unit to the left (x - 1, y - 2), the vertices would be A*(-1, -2), B*(0, 1), C*(0, -1)
If it is then rotated 90° clockwise about the origin, the new location is A'(-2, 1), B'(1, 0), C'(-1, 0)
Answer:
The coordinates of vertex A′ of ∆A′B′C′ are (-2, 1) .
The coordinates of vertex B′ of ∆A′B′C′ are (1, 0) .
The coordinates of vertex C′ of ∆A′B′C′ are (-1, 0) .

I need help with my homework , Please.
Answer:
Yes they are congruent.
Step-by-step explanation:
Congruent triangles are triangles that are the same size and shape. Since the triangle was split in half, both sides of the triangle are congruent to each other. If you fold the triangle, both will allign perfectly on top of one another.
Use one or more transformations to transform the pre-image (purple) onto the image (white).
Translate Rotate
* Reflect
(You cant tpuch the grey lines )
Answer: This is a translation of 12 units to the right.
translation written (x,y) -> (x+12,y+0)
Step-by-step explanation:
Pick a point on the pre-image, and count how many squares it has to move to end up at the corresponding point in the image.
Add that value to the coordinate x for horizontal movement, here +12.
Add to the coordinate y for vertical movement. here 0.

A construction company orders tile flooring for the kitchen and three bathrooms of a new home. The kitchen floor measures 48 square feet. Two bathrooms have floors that each measure square feet. The third bathroom floor measures square feet. If the tile costs $2.39 per square foot, what's the least amount of money, to the nearest cent, the company spends on tile for all three bathrooms
Step-by-step explanation:
The question is incomplete. Let us assume the two bathrooms have floors that each measure 24 square feet and third bathroom floor measures 18 square feet.
For the two bathrooms, the total area will be 2*24 = 48 square feet
Since the third bathroom measures 18 square feet, the total square feet for the 3 bathrooms is equal to 48sq. ft + 18 sq.ft = 64sq. ft
If the tile costs $2.39 per square foot, then the amount that 64sq. ft tiles will cost is expressed as:
1 sq. ft = $2..39
64sq.f = $x
Cross multiply:
1*x = 2.39* 64
x = $152.96
Hence the amount that the company's spent on tiles for the three bathrooms will be 15296 cents.
Note that the dimensions of bathrooms were assumed. You can follow the same procedure for any dimension given.

Answer:
0
Step-by-step explanation:
m=(y2-y1)/(x2-x1)
so m= (3-3)/(2-10)
m=0/-8

What is the solution to the linear equation?
4b + 6 = 2 – b + 4
Answer:
b = 0
Step-by-step explanation:
Subtract 6 from both sides:
4b = 2 - b - 2
Subtract 2 from two, and get 0.
4b = -b
this means that the only possible case where the equation is satisfied is when b = 0, because -0 is 0, and 4x0 is still 0.

Determine whether each statement about the design from the rug is true.
Ashti is designing a rug that uses shapes to tell a
story, similar to what rug weavers in her culture
have done for generations. She uses a computer
program to dilate the shapes for the design of the
rug. One of Ashti's designs is shown below with
labels for figures 1 and 2 and points X, Y,and Z.
Select True or False for each statement.
The center of dilation for figures 1 and 2 is point Y.
