step 2: ax^2 + bx = -c

Answers
Answer:C
Step-by-step explanation:
The derivation of the quadratic function is true
What is Quadratic Equation?A quadratic equation is a second-order polynomial equation in a single variable x , ax² + bx + c=0. with a ≠ 0. Because it is a second-order polynomial equation, the fundamental theorem of algebra guarantees that it has at least one solution. The solution may be real or complex.
The roots of the quadratic equations are
x = [ -b ± √ ( b² - 4ac ) ] / ( 2a )
where ( b² - 4ac ) is the discriminant
when ( b² - 4ac ) is positive, we get two real solutions
when discriminant is zero we get just one real solution (both answers are the same)
when discriminant is negative we get a pair of complex solutions
Given data ,
Let the quadratic equation be represented as A
Now , the value of A is
ax² + bx + c = 0
Step 1 :
ax² + bx + c = 0
Step 2 : Subtracting c on both sides , we get
ax² + bx = -c
Step 3 : Divide by x on both sides , we get
ax + b = -c/x
Hence , the steps are true in solving the quadratic equation

Diego measured the length of a pen to be 22 cm. The actual length of the pen is 23 cm. Which of these is closest to the percent error for Diego’s measurement. Explain your choice. [3 point]
4.3%
4.5%
95.7%
104.5%
Answers
Answer: its either a or b
Error is the difference between the actual length of an object and its measured length.
The closest to the percent error for Diego's measurement is 4.3%
Step 1: Find the error
Error = Actual length - Measured length
= 23cm - 22cm
= 1 cm
Step 2: Find the percent error
Formula = Error/ Actual length × 100
= 1 /23 × 10
= 4.35%
Therefore, the closest to the percent error for Diego's measurement is 4.3%

Margie bought 1 1/2
pounds of tomatoes for $2.00 per pound,
1/4 pound of onions for $1.60 per pound, and 1 pound of apples for $1.65 per pound. How much did she pay for her total purchase?
Answers
Answer:
She spent $5.05 for her total purchase.
Step-by-step explanation:
First, you should convert the fractions into decimals to make it easier, which would make it, 1.5, .25, 1.
Second, multiply 1.5 by 2 because there are 1.5 pounds which are payed for $2.00. Do the others fractions corresponding with the number of pounds and the cost this same way. 1.5 multiplied by 2 is 3. .25 multiplied by 1.60 is 0.4, 1 multiplied by 1.65 is 1.65.
Lastly, Add it all up, 3+0.4+1.65=5.05

Find the slope of the line parallel to 2x+3y=8
Answers
Answer:
Brandon
Step-by-step explanation:
2x + 3y = 8
-2x -2x
3y = -2x + 8
y = (-2/3)x + 8/3
m = (-2/3)
even tho brandon did not divide 8 by 3, you were just supposed to find the slope of the line parallel to that line so for the most part, he is correct for the way he got his answer
Answer:
slope = - [tex]\frac{2}{3}[/tex]
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Given
2x + 3y = 8 ( subtract 2x from both sides )
3y = - 2x + 8 ( divide all terms by 3 )
y = - [tex]\frac{2}{3}[/tex] x + [tex]\frac{8}{3}[/tex] ← in slope- intercept form
with slope m = - [tex]\frac{2}{3}[/tex]
Parallel lines have equal slopes , thus
slope of parallel line = - [tex]\frac{2}{3}[/tex]

1) If I'm reading it correctly, the two angles are vertically opposite. <4 = 72
2) <3 + <5 are supplementary (the add to 180) <5 = 180 - 134 = 46
3) <2 = 99 then <3 is 99 and < 6 = 99 (alternate interior angles)
<7 = <6
<7 = 99
Same side interior angles are supplementary.

Answers
The width of the playground is 4/3 miles.
What is the area of the rectangle?The formula for area is equal to the product of the length and breadth of the rectangle. Whereas when we speak about the perimeter of a rectangle, it is equal to the sum of all its four sides.
Given here, the length = 2/4 miles and Area = 8/12 miles
Thus width = 8/12 / 2/4
= 4/3 miles
Hence, the width of the playground is 4/3 miles.

Answers
Answer:
Use synthetic division to solve
Step-by-step explanation:
When dividing a polynomial by a zero, you first want to find the zero to divide by. Solving the zero (x+2) will give us the value of x to divide by. Subtracting 2 from each side gives us x=-2. Then, we write out the full polynomial. Since the only degrees that have numerical values are x^5 and 32, we substitute zero for the values in between (0x^4, 0x^3, 0x^2, and 0x). Then we follow the steps of synthetic division (as seen in the photo) to find our new values for our new equation.

The figures are similar. Find the missing length.Round to the nearest thousandth
Answers
Answer:
The missing x = 0.675 m
Step-by-step explanation:
In similar triangles, the corresponding sides are proportion (means their ratios are equal)
In the given figure
∵ The two triangles are similar
∴ Their corresponding sides are proportion
∵ The sides of lengths 1.8 m and x are corresponding sides
∵ The sides of lengths 8.0 m and 3.0 are corresponding sides
∴ [tex]\frac{1.8}{x}[/tex] = [tex]\frac{8.0}{3.0}[/tex]
→ By using cross multiplication
∴ x × 8.0 = 1.8 × 3.0
∴ 8x = 5.4
→ Divide both sides by 8
∵ [tex]\frac{8x}{8}[/tex] = [tex]\frac{5.4}{8}[/tex]
∴ x = 0.675
→ No rounding because there is no digit after the thousandth digit
∴ x = 0.675 m

What is fraction?The fractional bar is a horizontal bar that divides the numerator and denominator of every fraction into these two halves.
The number of parts into which the whole has been divided is shown by the denominator. It is positioned in the fraction's lower portion, below the fractional bar.How many sections of the fraction are displayed or chosen is shown in the numerator. It is positioned above the fractional bar in the upper portion of the fraction.Given:
1/3 + 1/6
Now, we have to add the fraction by focusing the numerator as
=1/3 + 1/6
Now, LCM(3, 6)= 6
= 1/3 x 2/2 + 1/6
=2/6 + 1/6
=(2+1)/6
=3/6
=1/2
Hence, the simplest form is 1/2.
