Andy and Sylvie each incorrectly simpilfied the expression: -3-4(2x-3).
Andy : -14x + 12
Sylvie: -8x - 6
Explain the errors and give the correct answer.
1. Observe problem
2. Simplify
-3-4(2x-3)
expand by distributive property
-3-8x+12
addition and subtraction
-8x+9
I have no idea what Andy And Sylvie were doing, so therefore...
I don't know which brain cell in there head is dysfunctional.
Answer:
-9 - 8x
Step-by-step explanation:
Andy multiplied incorrectly it should have been -4*2x, -4*-3
Sylvie forgot to multiply both sides she did -4*2x but forgot to do -4*-3
The correct answer should be...
-3-4(2x-3)
-3 - 8x + 12
-9 - 8x
You have been sent to grocery shop. They gave you $25.00 and the list of what
you need to buy, would you need more money or would you have enough money?
Here is the grocery list:
2 pounds of ham: $4.59/pound
3 bags of chips: $3.00/bag
2 loaves of bread: $1.99/loaf
Please calculate the above and write down how much it equals and what you will
have left after you buy it.
Answer:
you would have $2.98 left
Step-by-step explanation:
$4.59 x 2=9.18
3.00 x 3=9.00
$1.99 x 2=3.98
$9.18+$9.00+$3.98=22.16
$25.00-$22.16 = $2.89

Calculate the measures of x y z in the diagram given beloe
Step-by-step explanation:
Solution,
∠IDJ = 70° ( being alternate angle in AB || CD )
∠ IDJ + x = 180° ( being co-interior angle in EF || GH )
or , 70° + x = 180°
or , x = 180° - 70°
x = 110°
Again,
∠BLH = ∠CKG ( Being alternate angle in AB || CD )
y = 110°
Finally ,
z + y = 180° ( Being adjacent supplementary angle )
or , z + 110° = 180°
z = 70°
Thus , x = 110 ° , y = 110 ° and z = 70°

To make a perfect square of v² - 14v , add c such that:
We have:
a = 1 b = - 14 c = b²/ (4a) = (-14)²/ (4 × 1) = 49⇒ v² - 14v + 49 = (v - 7)(v - 7) = (v - 7)²
Answer: 49
OK done. Thank to me :>
Determine whether the following statement is true or false.
The ordered pairs (8,- 9) and (-9,8) name the same point.
Hi!
I can help you with joy!
Are these ordered pairs the same? Do they name the same point?
(8, -9) and (-9,8) are our points.
The x-coordinate of one point is 8, and the x-coordinate of the second point is -9.
The y-coordinate of the first point is -9, and the y-coordinate of the second point is 8.
Thus, these 2 ordered pairs do not name the same point.
The statement is false.
I hope this helps!

Perpendicular bisectorAngle bisectorMedianAltitudeMs. Jacobi writes the equation x+y=z. If x = 5, y = 3, and z = 53,
is the equation true? Explain your reasoning.
Answer:
no
Step-by-step explanation:
Because if we substitute the value of x,y and z we get
x+y=z
5+3=53(FALSE)
Answer and Step-by-step explanation:
No, this equation is not true. But in order to show this, we need to write out the equation. So if x = 5, and y = 3, then the equation for this equation would look like this:
5 + 3 = 8.
That is incorrect because 5 + 3 does not equal 53. This is a trick question that is trying to trick you. Now if that 5 was a 50, then this equation would be true.
So, 5 + 3 ≠ 53.
I hope that this helps.
Which expression is equivalent to 3^-2 times 5^-2
a. 1/15^2
b. 1/15^-2
c. 15^4
d. 15^-4
Answer:
The answer would be A)
Step-by-step explanation:
3^-2 = 1/9
5^-2 = 1/25
1/9 * 1/25 = 1/225
15^2 = 225
meaning,
3^-2 * 5^-2 = 1/15^2
Hope this helps yo! :)

In the figure below, XZ=35 and YZ=17. Find XY.
Answer:
XY = 18
Step-by-step explanation:
XY → XZ - YZ [ here given XZ is 35 and YZ is 17 ]
XY → 35 - 17 [ subtracting ]
XY → 18 [ final answer ]
Let XY be x
XY+YZ=XZPut values
17+x=35x=35-17x=18XY=18
