The equation of line that passes through point (-1,2) and which is perpendicular to 2y = 2x – 1 will be y = -x + 1.
Equation of lineThe General equation of a line is ax + by + c = 0
How to solve this problem? Since the line is perpendicular to 2y=2x-1, this means that its slope with be the opposite reciprocal of the line 2y=2x-1 ‘s slope.First, we should find the slope of the line 2y=2x-1:2y=2x-1
y=x-1/2
Therefore, the slope of 2y=2x-1 is 1 and the opposite reciprocal of 1 is -1 So far, we have this: y=-x+bTo find b (the y-intercept) we can plug the point (-1,2) into the equation we have so far and solve for b.y=-x+b
2=-(-1)+b
2=1+b
b=1
So, the equation of the line that passes through (-1,2) and which is perpendicular to 2y=2x-1 is y=-x+b

which expression represents purely real numbers and which expression represents non-real complex number?
Incomplete question. However, I provided some explanation about non-real complex numbers.
Explanation:
In Mathematics, the term complex numbers (non-real complex numbers) in simple terms refers to numbers that containing an imaginary addition to it.
For example, the numbers 3i, 3 + 5i, 3i/4 are non-real numbers because of the addition of an imaginary part which is denoted by 'i'.
While real numbers, on the other hand, are numbers that do not include an imaginary part; they stand on their own, such as whole numbers 0, 1, 2, 3, etc, rational numbers like 3/4, etc.

Answer:
x = 67°Step-by-step explanation:
The sum of measures of angles in triangle is allways 180°
So:
x + 53° + 60° = 180° {subtract 113° from both sides}
x = 67°

there are 11 2/7's in 3 with a remainder of 1/7, 11 1/7.
Step-by-step explanation:
Answer:
10.5 or 21/2
Step-by-step explanation:
The question is asking how many 2/7 are in 3. So let make 3 a equivalent fraction that has 7 as it denomanater. 7/7 is 1, 14/7 is 2, so 21/7 is 3. Now let divide 21/7 by 2/7. flip 2/7 around to 7/2 then multiply by 21/7 which equals
[tex]\frac{147}{14}[/tex] which equals 10.5 or 21/2.

the volume of a box is 45x^3 + 198x^2 + 189x. find expressions for the possible dimensions of the prism
Answer:
length, width, and height are (b+2), (b-2), (b+3)
Step-by-step explanation:
Doing what the problem statement tells you to do, you get ...
(b^3 +3b^2) -(4b +12)
= b^2(b +3) -4(b +3) . . . factor each pair of terms
= (b^2 -4)(b +3) . . . write as a product
= (b -2)(b +2)(b +3) . . . use the factoring of the difference of squares
The three factors are (b-2) , (b+2) , and (b+3). We have no clue as to how to associate those with length, width, and height. We just know these are the dimensions of the box.
The possible dimensions of the prism are:
Length: 9x, 5x + 7, or x + 3
Width: 5x + 7, x + 3, or 9x
Height: x + 3, 9x, or 5x + 7
What is a prism?A prism is a three-dimensional object.
There are triangular prism and rectangular prism.
We have,
To find the possible dimensions of the prism, we need to factor the given volume expression into three factors, each representing the length, width, and height of the box.
We start by looking for common factors among the coefficients of the three terms:
45x³ + 198x² + 189x
= 9x (5x² + 22x + 21)
Now we can factor the quadratic expression inside the parentheses:
5x² + 22x + 21
= 5x² + 15x + 7x + 21
= 5x(x + 3) + 7(x + 3)
= (5x + 7) (x + 3)
The volume expression can be factored as:
45x³ + 198x² + 189x
= 9x (5x + 7) (x + 3)
Thus,
The possible dimensions of the prism are:
Length: 9x, 5x + 7, or x + 3
Width: 5x + 7, x + 3, or 9x
Height: x + 3, 9x, or 5x + 7

24 in.2
108 in.2
224 in.2
486 in.2
Answer: 486 in
Just did this on edge
The enlargement transformation applied to the rectangular figure gives
a rectangle that is enlarged and similar to the figure.
Correct response:
The area of the enlarged picture is 486 in.²The given dimensions of the picture are;
Height, [tex]\overline{MN}[/tex] = 6 in.
Width, [tex]\overline{LP}[/tex] = 4 in.
The length of QL' = 12 + 42 = 54
By similar triangles, we have;
[tex]\dfrac{\overline{L'P'}}{\overline{LP}} = \mathbf{ \dfrac{\overline{QL'}}{\overline{QL}}}[/tex]
Which gives;
[tex]\dfrac{\overline{L'P'}}{6} = \mathbf{ \dfrac{54}{12}}[/tex]
[tex]\overline{L'P'} = \dfrac{54 }{12} \times 6 = \mathbf{27}[/tex]
Given that an enlargement gives similar figures, we have;
[tex]\dfrac{\overline{L'P'}}{\overline{LP}} = \mathbf{\dfrac{\overline{L'M'}}{\overline{LM}}} = Scale \, factor \ of \ the \ enlargement[/tex]
Therefore;
[tex]\dfrac{27}{6} = \dfrac{\overline{L'M'}}{4}[/tex]
Which gives;
[tex]\overline{L'M'} = \dfrac{27}{6} \times 4 = \mathbf{ 18}[/tex]
The area of the enlarged picture is, A = [tex]\overline{L'M'}[/tex] × [tex]\overline{L'P'}[/tex]
Which gives;
A = 27 × 18 = 486
The area of the enlarged picture on the wall is A = 486 in.²

show me a Graph x=−4.
Answer:
The graph of line x = -4 is also attached below.
The graph indicates that no matter what the value of y is, the x-value remains the same. Hence, the line is vertical with undefined slope,
Step-by-step explanation:
Given the line
x=−4
The given line x=-4 represents the vertical. We know that the slope of a vertical line is undefined. Thus, the slope of x=-4 is undefined.
As the line is vertical, meaning no matter what the value of y is, the x-value remains the same.
The graph of the line x = -4 is also attached below.
The graph indicates that no matter what the value of y is, the x-value remains the same. Hence, the line is vertical with undefined slope,
