Answer:
the answer is B. He should have only multiplied 3 by –2 resulting in the expression 5y – 6.
Step-by-step explanation:
In the given expressions, the reason for John's claim being incorrect would be:
B). He should have only multiplied 3 by –2 resulting in the expression 5y – 6.
Given,
The two expressions i.e. [tex](-215y - 3) = - 10y - 6[/tex]The mistake that John makes is that he multiplies the entire equation by -2 as shown in [tex]= (-2x5y) - (-2x - 3)[/tex] which makes it incorrect.In order to rectify this mistake, only 3 was suppossed to be multiplied by -2 so that the outcome comes out as [tex]5y - 6[/tex].Thus, option B is the correct answer.

A playground is rectangular with a length of 1/2
miles. If the area of the playground is 5/8
square miles, what is its width? Input your answer as a fraction. Need help ASAP for a grade
Answer:5/4
Step-by-step explanation:
Area = length* width
5/8 = 1/2 * width
Width = 5/4
Answer:
5/4 miles.
Step-by-step explanation:
Width = area / length
= 5/8 / 1/2
= 5/8 * 2
= 10/8
= 5/4 miles.

I need help with linear regression
Answer:
In statistics, linear regression is a linear approach to modelling the relationship between a scalar response (or dependent variable) and one or more explanatory variables (or independent variables). The case of one explanatory variable is called simple linear regression. For more than one explanatory variable, the process is called multiple linear regression. This term is distinct from multivariate linear regression, where multiple correlated dependent variables are predicted, rather than a single scalar variable.
the figure is symmetric about the x- and y-axis. what is the area of the figure below
Answer:
126 units²
Step-by-step explanation:
Draw 5 vertical lines BR, CQ, EO, GM, HL and we will have 4 trapezoids and 2 rectangles.
Trapezoid ABRS ≅ trapezoid IHLK
Trapezoid DEOP ≅ trapezoid FEON
Rectangle BCQR ≅ rectangle GHLM
Area of trapezoid is [tex]\frac{b_{1} +b_{2} }{2}h[/tex]
Area of rectangle is [tex]lw[/tex]
The total area of the figure is: ( 2 × [tex]A_{ABRS}[/tex] + 2 × [tex]A_{BCQR}[/tex] + 2 × [tex]A_{DEOP}[/tex] )
In trapezoid ABRS: [tex]b_{1}[/tex] = 6, [tex]b_{2}[/tex] = 8 and h = 3 ⇒
2 × [tex]A_{ABRS}[/tex] = 2 × [3(6 + 8) ÷ 2] = 42 units²
In rectangle BCQR: l = 6 and w = 3 ⇒
2 × [tex]A_{BCQR}[/tex] = 2 × (6 × 3) = 36 units²
In trapezoid DEOP: [tex]b_{1}[/tex] = 6, [tex]b_{2}[/tex] = 10 and h = 3 ⇒
2 × [tex]A_{DEOP}[/tex] = 2 × [3(6 + 10) ÷ 2] = 48 units²
[tex]A_{total}[/tex] = 42 + 36 + 48 = 126 units²

Figure ABCD is transformed to obtain figure A′B′C′D′:
A coordinate grid is shown from negative 6 to 6 on both axes at increments of 1. Figure ABCD has A at ordered pair negative 4, 4, B at negative 2, 2, C at negative 2, negative 1, D at negative 4, 1. Figure A prime B prime C prime D prime has A prime at ordered pair 3, negative 4, B prime at 5, negative 2, C prime at 5, 1, D prime at 3, negative 1. Part A: Write the sequence of transformations that changes figure ABCD to figure A′B′C′D′. Explain your answer and write the coordinates of the figure obtained after each transformation. (6 points)
Part B: Are the two figures congruent? Explain your answer.
Answer
:Reflected along x axis
Translated 7 units to the righ
A transformation of a point is the movement of the point from its initial position to a new position. If an object is transformed, all its points are also transformed. Types of transformation are reflection, rotation, dilation and translation.
Figure ABCD has A at (- 4, 4), B at (- 2, 2), C at (- 2, - 1), D at (- 4, 1).
If a point (x, y) is reflected along the x axis, its x coordinate remains the same and the y coordinate is opposite (negated). The new point is at (x, -y)
If a point (x, y) is translated h units to the right, the new coordinate is (x+h, y).The transformation are as follows:
It is reflected along the x axis so that the new coordinates would be at A1 at (- 4, -4), B1 at (- 2, -2), C1 at (- 2, 1), D1 at (- 4, -1)
It is translated 7 units to the right, The new coordinates are A' at (3, -4), B' at (5, -2), C' at (5, 1), D' at (3, -1)

Can i get brainliest plz, im trying to unpgrade my rank!
Alright, I am hoping this is an flvs question, and that it comes from the quiz.
I came to this question because I needed help on it, but now I understand it, so im gonna help others :)
For Part A, the answer would be reflected on the x axis, translated 7 units to the right. This is true because by only reflecting it, the figure would not be on the exact spot. We have to translate it to the right.
For part B, the simple answer is that they are NOT congruent. As shown, they have been translated and moved, so in conclusion, they are not congruent. PLS MARK BRAINLIEST, not trying to be mean or anything, but I need it way more than the other person if you look at our ranks.

-4x = 22
Answer:
x=-5.5
Step-by-step explanation:
This equation has already been simplified to the last part for you so all you have to do is divide 22 by -4 and you get -5.5
22/-4=-5.5
Answer:
x = -5.5
Step-by-step explanation:
To answer this you need to isolate the x.. So -4x/-4 and then do the same to 22. So 22/-4 = -5.5
The answer is x = -5.5
Angle Theorems for triangles
Answer:
Step-by-step explanation:
The interior angles of a triangle add to 180°:a + b + c = 180°
Angles c and d make a straight angle, which is 180°:d + c = 180°
So d + c equals a + b + c:d + c = a + b + c.
Subtract c from both sides:d = a + b.
A bag contains 8 red pens, 7 blue pens, and 14 black pens. Denato will pull a pen from the bag.
When Denato pulls a pen from the bag, how many outcomes are possible?
A.8
B.7
C.14
D.29
20 POINTS!!
The probability helps us to know the chances of an event occurring. The number of possible outcomes When Denato pulls a pen from the bag is 29.
What is Probability?The probability helps us to know the chances of an event occurring.
[tex]\rm Probability=\dfrac{Desired\ Outcomes}{Total\ Number\ of\ outcomes\ possible}[/tex]
Given that the bag has 8 red pens, 7 blue pens, and 14 black pens. Therefore, if Denato will pull a pen from the bag the number of possibilities will be the sum of all the number of pens.
Number of Possibilities = 8 + 7 + 14 = 29
Thus, the number of possible outcomes When Denato pulls a pen from the bag is 29.

A book weighs 0.65 kg. A printing company packs 5 copies of
the book in a box. How much do the books in the box weigh?
Answer:
3.25 kg
Step-by-step explanation:
Since there are five books in the box, and one book weighs 0.65 kg, you just have to multiply 0.65 by five.
0.65(5)=3.25. So the answer is 3.25kg
A company orders 18 boxed lunches from a deli for $223.20. If each boxed lunch costs the same amount, what is the unit cost of each boxed lunch?
Answer:
12.40
Step-by-step explanation:
[tex]223.20 \div 18[/tex]
that will give you the answer of 12.40 for each unit.
Answer:
Step-by-step explanation:
1 box costs x amount
18 boxes cos 223.20
Cross multiply
223.20 * 1 = 18 x
Divide by 18
223.20 / 18 = 18x / 18
x = 12.40
Cost of 1 box is 12.40
Which statements about the Commutative Property of Multiplication are TRUE? Select all that apply. A. The property applies to all real numbers. B. The property states that ab is equivalent to ba. a ( x + y ) = ax + ay C. There is also a Commutative Property of Division because multiplication and division are related operations. D. The property states that when multiplying three numbers together, you can multiply any two of them first and then multiply by the remaining number.
Answer:
b) The property states that ab is equivalent to b a
Step-by-step explanation:
Commutative property:-
the commutative property , when we multiply two integers , the answer we get after multiplication will remain the same, even if the position of the integers are interchanged.
Let 'a' and 'b' be the two integers , then ab = b a
Example:-
. 1 X 2 = 2 X 1 = 2
. 12 X 5 = 5 X 12 = 60

XYZ shown below has a measure of (8x + 12)°. The measure of 1 is (4x + 8)°, and the measure of 2 is (9x - 11).
What is the measure of ZXYZ?
A 3
B 20°
C 36°
D 60
Answer:
C
Step-by-step explanation:
∠ XYZ = ∠ 1 + ∠ 2, substitute values
8x + 12 = 4x + 8 + 9x - 11 = 13x - 3 ( subtract 13x from both sides )
- 5x + 12 = - 3 ( subtract 12 from both sides )
- 5x = - 15 ( divide both sides by - 5 )
x = 3
Thus
∠ XYZ = 8x + 12 = 8(3) + 12 = 24 + 12 = 36° → C
