Complete the square so that the left side of x2 + 8x − 3 = 0 becomes a binomial squared.

Answer:

Option (A)

Step-by-step explanation:

Three squares shown in the figure are formed on the sides of the given right triangle.

By Pythagoras theorem,

(Hypotenuse)² = (Leg 1)² + (Leg 2)²

Area of the square on the hypotenuse = Area of the square on the leg 1 + Area of the square on leg 2

Option (A).

95 = 40 + 55

True.

Option (B).

45 ≠ 35 + 25

False.

Option (C).

100 ≠ 10 + 10

False.

Option (D).

1200 ≠ 40 + 30

False

Therefore, Option (A) shows the areas of three squares.

Answer:

f(-3) = 7

Step-by-step explanation:

For these types of questions, you need to replace the x's in the equation with whatever is inside f(x)

So if its f(5) you would sub 5 into where all the x's are

(a-6)(a+1)

a=6, -1

Answer: 2x-9y=1

Step-by-step explanation:

(this is how i found it don't know if this is how you learned it though)

Subtract 20 from both sides of -3x-8y=20, so that it becomes -3x-8y-20

Subtract 19 from both sides of -5x+y=19, so you get -5x+y-19

Subtract like terms from both equations (-3x-8y-20)-(-5x+y-19), which gives you 2x-9y-1

-3--5=2, -8-1=-9, -20--19=-1

Add 1 to both sides and you get 2x-9y=1

Step-by-step explanation:

y = 2x + b/y=mx+c use this equation to solve the sum

using y=mx+c  to solve the sum

y=2, x=-3 and m=4/3

after putting and simplfying the eq we get the value of m

im not for sure but I think the answer is 9! my reasoning is below,,

Step-by-step explanation:

[tex] \frac{49}{7} = \frac{63}{x} [/tex]

do the crossing method and it would result in this

(49×x) = (63×7)

after simplifying both sides

49x = 441

divide both sides by 49 and the result will be

x = 9 !!

Answer:

what is the question

Step-by-step explanation:

Answer:

x= 3

Step-by-step explanation:

1. -5(3) + 2 = -13      

2. -15 + 2 = -13         A positive times a negative will always equal a negative

3. -13 = -13         Whenever you add anything to a negative number, the                    

                           number becomes smaller  

                     Ex:  -10, -9, -8, -7, -6, -5, -4, -3, -2, -1, 0, 1, 2, 3, ...........

                           Although the number itself becomes smaller, its value    

                            becomes bigger      

Hope this helps.

Answer:

[tex]x=43\\[/tex]°

Step-by-step explanation:

considering m║n, the two labeled angles are alternate exterior angles. alternate exterior angles are equivalent. So you will have an equation of:

[tex]4x-27=3x+16[/tex]. Add 27 on both sides and get: [tex]4x=3x+43[/tex]. subtract [tex]3x[/tex] from both sides to get: [tex]x=43[/tex]°.

Answer:

0.0637

Step-by-step explanation:

hope this helps :)

6.37 x 10⁻² in the standard form is 0.0637.

Decimals are numbers that have two components, a whole number component and a fractional component, which are separated by a decimal point.

We have an expression,

6.37 x 10⁻².

Simplifying to standard form.

6.37 x 10⁻²,

= 6.37 x 1/100

= 6.37/100

= 0.0637

Therefore, 0.0637 is the standard form.

Answer:

x = 6 or x = -5

Step-by-step explanation:

x^2 - 30 = x

x^2 - x - 30 = 0

(x - 6)(x + 5) = 0

x - 6 = 0 or x + 5 = 0

x = 6 or x = -5

Answer:

3.33hours

Step-by-step explanation:

Where the number of hours = h

the prices of stock A at 9am was $12.18 since then the price has been increasing at the rate of $0.06 each hour.

The Algebraic expression =

$12.18 + $0.06 × h

12.18 + 0.06h

At noon the price of stock B was $12.68. It begins to descrease at the rate of $0.09 per hour.

$12.68 - $0.09×h

12.68 - 0.09h

If the 2 rates continue in how many hours will the prices of the two stocks be the same?

Stock A = Stock B

12.18 + 0.06h = 12.68 - 0.09h

Collect like terms

0.06h + 0.09h = 12.68 - 12.18

0.15h = 0.5

h = 0.5/0.15

h = 3.3333333333 hours

h = 3.33hours
