a square with a side length of 2 units is drawn on the coordinate plane with a vertex at the origin. Which shows a dilation of the square by a scale factor of 2
Answer:
Step-by-step explanation:
From the figure attached,
ABCD is a square with vertices as,
A(-2, 0), B(-2, 2), C(0, 2) and D(0, 0)
If the given square is dilated by a scale factor of 2 and the center of dilation is the point D (origin).
Rule for the dilation of a point by a scale factor k is,
(x, y) → (kx, ky)
By this rule,
A(-2, 0) → A'(-4, 0)
B(-2, 2) → B'(-4, 4)
C(0, 2) → C'(0, 4)
D(0, 0) → D'(0, 0)
Now we can plot these points to get the image square (dilated figure) as given the figure attached.

Answer:
6
Step-by-step explanation:
8(1/2) + 2(4)
/2
4 + 8
/2
12/2
6
Answer:
The answer is 6.
Step-by-step explanation:
SInce x = 1/2, we multiply 8 by 1/2 which is 4.
y = 4, so 2 x 4 = 8. 8 + 4 = 12.
we divide by z, which is 2, so 12 ÷ 2 = 6.
hope this helped!
enter your answer as a simplified fraction formatted like this: 42/53
the answer on there is wrong
Answer:
[tex]\displaystyle -0.\overline{37}=-\frac{37}{99}[/tex]
Step-by-step explanation:
Convert a Repeating Decimal to a Fraction
We need to convert the following decimal to a fraction:
[tex]-0.\overline{37}[/tex]
Let's call x to the given number:
[tex]x=-0.\overline{37}[/tex]
The number has two repeating (periodic) decimals, thus we multiply by 100:
[tex]100x=-37.\overline{37}[/tex]
Note the decimals continue to repeat exactly like the original number.
Subtracting both expressións, the repeating decimals are simplified:
[tex]100x - x = -37[/tex]
Operating:
99x=-37
Dividing by 99:
[tex]\displaystyle x=-\frac{37}{99}[/tex]
The fraction cannot be simplified, thus:
[tex]\mathbf{\displaystyle -0.\overline{37}=-\frac{37}{99}}[/tex]

how do you factor 18x^2-18x-5?
Answer:
This expresion is not factorable. If you have any questions, please ask me!
The volume V (in cubic feet) of a rectangular room can be modeled by V(x)= 2x^3-14x^2+12x, where x is the length (in feet) if the room. Factor the function. Use your factorization to determined the values of x for which the model makes sense
Answer:
The values of x for which the model makes sense is [tex]x\ge 6\,ft[/tex].
Step-by-step explanation:
From statement we have the following expression for the volume of the rectangular room is:
[tex]V(x) = 2\cdot x^{3}-14\cdot x^{2}+12\cdot x[/tex] (1)
Where:
[tex]V[/tex] - Volume of the rectangular room, measured in cubic feet.
[tex]x[/tex] - Length of the room, measured in feet.
By Algebraic means we factorize the polynomial:
[tex]V(x) = x\cdot (2\cdot x^{2}-14\cdot x +12)[/tex]
[tex]V(x) = x\cdot (x-6)\cdot (x-1)[/tex]
Given that both volume and length must be positive variables, then the following conditions must be satisfied:
[tex]x \ge 0\,ft\,\land\,x\ge 6\,ft\,\land\,x\ge 1\,ft[/tex]
Then, the values of x for which the model makes sense is [tex]x\ge 6\,ft[/tex].
8. What is the solution of the equation 4x + 12 = 48 ?
a) x= 9
b) x= 15
c) x= 144
d) x= 240
Answer:
A) x=9
Step-by-step explanation:
48-12=36.
36/4=9
More detailed explanation:
4x+12=48
-12 -12
4x = 36
/4 /4
x = 9
The solution of the equation is, x = 9.
What is an expression?Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
We have to given that;
The equation is,
⇒ 4x + 12 = 48
Now, We can solve the equation for value of x as;
⇒ 4x + 12 = 48
Subtract 12 both side, we get;
⇒ 4x + 12 - 12 = 48 - 12
⇒ 4x = 36
Divide by 4;
⇒ 4x/4 = 36/4
⇒ x = 9

Be positive or negative? Explain why or why not.
This is a personal question!
Answer:
It would be positive
Step-by-step explanation:
To do anything with fractions you need to find a common denominator, in this case lets say its 128. the 9 in the negative side would need to be multiplied by 8 like it's denominator making it 72. You would do the same to the other fraction giving you the fractions -72/128 and 144/128 from here you add to get 72/128 which is positive
Answer:
positive
Step-by-step explanation:
-9/16= -0.5625
9/8= 1.125
-9/16+9/8= -0.5625 + 1.125(in the addition of opposite signs u should figure out the largest num and should substract the other numa nd assign the sign of the biggest nym)
=0.5625
