Lupita completed the square to solve the equation 0 = x2 - 6x +13 as follows.
Lupita made a mistake. In which step did the error occur and what was the error? Finally
complete the problem with the mistake fixed and give the solutions to the equation.
The solution to the equation is x = ±[tex]\sqrt{2}[/tex]i +3
What is a quadratic equation ?A quadratic equation is an algebraic equation which has highest degree of 2 and it has 2 roots.
In the given question
x² - 6x +13 = 0
x² - 2.x.b + 13 = 0 (-2.x.b = -6x ↔ b = 3)
(x - 3)² + 13 = 9 ( we have added 9 on r.h.s
because b² = 9 is added on l.h.s)
(x-3)² = -4
x - 3 = ±[tex]\sqrt{2}[/tex]i
x = ±[tex]\sqrt{2}[/tex]i +3
She made a mistake in the second step she should have added +9 on the right hand side because we have an additional 9 on the left hand side because of the perfect square we have made to make both sides balanced.

⇒ 20 / 32
We have to given that,
To simplify fraction 10/16 to lowest terms and equivalent fraction that has a denominator of 32.
We have,
⇒ 10 / 16
⇒ 10 ÷ 2 / 16 ÷ 2
⇒ 5 / 8
Therefore, The lowest terms of fraction are, 5/8
And, Let the numerator of the fraction with denominator 32 is, x
Hence, It can be written as,
⇒ x / 32
Equivalent to 10/16,
⇒ 10/16 = x/32
⇒ 32 x 10 = 16x
⇒ 320 = 16x
⇒ x = 20
Therefore, The equivalent fraction that has a denominator of 32 is,
⇒ 20 / 32

Answer:
∠BEC, ∠CED83°139°90°Step-by-step explanation:
When it comes to angles in a plane, the whole is the sum of the parts.
The little square in the corner of angle BED tells you that is a right angle, so has a measure of 90°. (This is the answer to part 4.) It also tells you that any ray between EB and ED will divide this angle into two complementary angles--angles that have a sum of 90°. There is only one such ray, EC, and it divides angle BED into angles BEC and CED.
1. Angles BEC and CED are adjacent complementary angles.
__
2. The parts of angle AEC are angles AEB and BEC. Angle AEC is the sum of those parts:
∠AEC = 49° +34° = 83°
__
3. Angle AED is the sum of angle AEB and right angle BED:
∠AED = 49° +90° = 139°
__
4. As we saw above, the marking on the figure tells you ...
∠BED = 90°
What is the equation in point-slope form of a line that passes through the points (3, −5) and (−8, 4) ?
Answer:
y = -9/11x - 28/11
Step-by-step explanation:
y2 - y1 / x2 - x1
4 - (-5) / -8 - 3
9/-11
= -9/11
y = -9/11x + b
4 = -9/11(-8) + b
4 = 72/11 + b
-28/11

4. Reflection across the y-axis
Answer:
F' = (2 , -4)
G' = (-1 , -3)
H' = (4 , 0)
I' = (5 , -2)
Step-by-step explanation:
To get the coordinate points of a figure that is reflected across the y-axis, perform the following action to each point:
(x , y) → (-x , y)
Using this will give the points of F', G', H', and I'.
To find the new points, plug in the values into the formula:
F → F' = (-2 , -4) → (2 , -4)
G → G' = (1 , -3) → (-1 , -3)
H → H' = (-4 , 0) → (4 , 0)
I → I' = (-5 , -2) → (5 , -2)
To graph the new figure, plot the new points and connect them. At each point, remember to label them with the corresponding letter as well as the ' symbol.

A moderately active man weighing 175 pounds should consume no more than 687 calories per day from fat sources. If fat contains 9 calories per gram, what is the maximum number of grams of fat he should consume? Give me a whole number or decimal rounded to one decimal place. Thanks! Expert only please.
According to the question, therefore, the maximum number of grams of fat he should consume will be 76.3 grams.
Step-by-step explanation:-Directly divide 687 by 9 as both are fat content. Therefore, by dividing them, we get to know about how grams of fat can be consumed.
