The first three steps of completing the square to solve the quadratic equation 2? + 8x + 5 = 0 are shown
below.
Step 1: x² + 8.0 = -5
Step 2: x2 + 8x + 16 = -5+16
Step 3: (x + 4)2 = 11
What are the next 3 steps?
Answer:
x = 3/2
Step-by-step explanation:
Step 4: 2x + 8 = 11
step 5: 2x +8 - 8 = 11 -8
step 6: 2x/2 = 3/2
step 7: x = 3/2
Answer:
see explanation
Step-by-step explanation:
take the square root of both sides
step 4 : x + 4 = ± [tex]\sqrt{11}[/tex] ( subtract 4 from both sides )
step 5 : x = - 4 ± [tex]\sqrt{11}[/tex]
step 6 : x = - 4 - [tex]\sqrt{11}[/tex] , x = - 4 + [tex]\sqrt{11}[/tex]
what is the y-intercept?
The y intercept is where a line on a graph crosses the y axis when the x coordinate is 0.
Answer:
The point where the line is on the Y axis
Step-by-step explanation:
for example in the equation y=mx+b, b would be the y-intercept or in the equation y=4x+7, the y-intercept would be 7.

You can buy 5 cans for green beans at the Village Market for $2.60. You can buy 10 of the same cans of beans at Sam's Club for $5.50. Which place is the better buy?
Answer:
Village market
Step-by-step explanation:
What you want to do is times the 5 for 2.60 deal by two since 5x2 is 10, and 10 of cans of green beans at Sam's club is 5.50
5x2=10

An icicle drips at a rate that can be represented by the function f(x) = −x2 11x − 18, where 0 ≤ x ≤ 10 and x is the number of hours after the sun has risen. when f(x) is a negative number, the icicle is not dripping. determine the values when the icicle starts and stops dripping. x = 2 and x = 9 x = −2 and x = 9 x = 2 and x = −9 x = −2 and x = −9
Quadratic functions are functions that have a leading degree of 2. The values when the icicle starts and stops dripping is at x = 2 and 9
Application of intercepts of a functionQuadratic functions are functions that have a leading degree of 2.
Given the equation that represents the rate at which an icicle drips below:
f(x) = −x^2 + 11x − 18
If the icicle is not dripping at the point where f(x) is a negative number, hence point where the icicle starts and stops dripping is the point where f(x) =0
Substitute
−x^2 + 11x − 18 = 0
x^2 - 11x + 18 = 0
x^2 - 9x - 2x + 18 =0
x(x - 9)-2(x-9) = 0
x = 2 and 9
Hence the values when the icicle starts and stops dripping is at x = 2 and 9

The average speed for a family trip is 62 miles per hour. Which equation models the distance traveled d and time in hours t?
Answer: d = speed × t or d= velocity × time
d = 62t
Step-by-step explanation: See above
From the top of a lighthouse 160 feet above sea level, the angle of depression to a boat
at
sea is 25 degrees. To the nearest foot, what is the horizontal distance from the boat to
the base of the lighthouse?
Answer:
75 feet
Step-by-step explanation:
The perpendicular height from the base of the lighthouse to the top is 160 feet. The angle of depression is the angle that is adjacent to this side. The opposite of this angle is the horizontal distance from the boat to the base of the lighthouse, so we need to use the tangent. tan 25°=x/160, tan 25° is 0.466 so when we multiplty by 160 to find x, we get x=74.56, which rounded up is 75.

Joy is making hand-painted ornaments for
her family this year. Yesterday, she made 2
ornaments in 6 hours. This weekend, she
plans to spend a total of 15 hours making
ornaments.
If Joy works at the same rate, how many
ornaments will she make this weekend?
Answer:
1 ornament per 3 hours
in 15 hours she will have 7.5 of them done
Answer:
5 Ornaments
Step-by-step explanation:
First, we take into account that 24 hours are in one day. We then make the equation 6/24, which tells us that she can make 8 ornaments in 24 hours. That's not the answer we need though.
We will divide 2 by 6 = 0.33
We can take that and multiply it by 15 hours to get 5 ornaments total.
Hope this answer helped u out :D

Multiply the binomials:
Answer:
2y² + y - 15
Step-by-step explanation:
ConceptsMultiplying Binomials:To multiply binomials, it's best to use the FOIL method, which stands for First, Outside, Inside, and Last. Let's analyze the first, outside, inside, and last term in the binomial we're given by bolding them (in addition, the numbers we bolded are the numbers we multiply; i.e. for the first term, we multiply y and 2y):
First: (y + 3)(2y - 5)Outside: (y + 3)(2y - 5)Inside: (y + 3)(2y - 5)Last: (y + 3)(2y - 5) SolvingSolving the BinomialStep 1: Apply FOIL method.
[tex](y)(2y) + (y)(-5) + (3)(2y) + (3)(-5)[/tex] [tex]2y^2 -5y +6y -15[/tex]Step 2: Simplify.
[tex](2y^2)+ (-5y+6y)+(-15)[/tex] [tex]2y^2+y-15[/tex]Therefore, the answer is 2y² + y - 15.

Find the distance between the two points in simplest radical form.
(1, -7) and (7,0)
Answer:
The distance between the two given points is equal to √85.
Step-by-step explanation:
Let's recall what the distance formula is:
[tex]\displaystyle \huge\math\boxed{d = \sqrt{(x_1 - x_2)^2 + (y_1 - y_2)^2} }[/tex]
We are defined our two points as:
(x₁, y₁) → (1, -7)(x₂, y₂) → (7, 0)We can rewrite this into our different "variables":
x₁ = 1y₁ = -7x₂ = 7y₂ = 0Now given our distance formula and our variables, we can find the distance between the two points:
[tex]\displaystyle\huge\begin{aligned}d & = \sqrt{(1 - 7)^2 + (7 - 0)^2} \\& = \sqrt{(-6)^2 + (7)^2} \\& = \sqrt{36 + 49} \\& = \math\boxed{\sqrt{85}} \\\end{aligned}[/tex]
∴ since the radical is already in its simplest form, our distance between the two points is equal to √85.
