Answer:

[tex]x=0, \quad x=-7[/tex]

Step-by-step explanation:

Given equation:

[tex]x^2+7x=0[/tex]

Factor x from the left side of the equation:

[tex]\implies x(x+7)=0[/tex]

Using the Zero Product Property, set each factor equal to zero and solve for x:

[tex]\implies x=0[/tex]

[tex]\implies x+7=0 \implies x=-7[/tex]

Therefore, the solutions of the equation are:

[tex]x=0, \quad x=-7[/tex]

Zero Product Property: If a⋅b = 0 then either a = 0 or b = 0 (or both).

The answer is to this problem is five over three

The data in the question will be represented by a geometric sequence given by 3 (2) ⁿ⁻¹.

A geometric sequence is defined as the sequence in which the ratio between the consecutive terms of the sequence remains constant. The ratio is known as common ratio. The nth term of geometric sequence is written as a (r)ⁿ⁻¹ where a is the first term, r is the common ratio and n is the number of terms. We know from the question that the time in minutes Aurora takes to complete the task forms a sequence as 3, 6, 12, 24.....

The common ratio of this sequence is given by 6/3 = 2. The first term being equal to 3. Now, for the nth term the sequence will be represented as

a (r)ⁿ⁻¹

=> 3 (2)ⁿ⁻¹

we can determine the part of the graph to be shaded if the equation changes to the inequality:

If we make y the subject of the formula, such that

Then we can put in the values of x and y at (0,0)

so that

we can see that the expression is false because 0 is not greater than 1

Hence, we will shade away from the origin this means that we will shade above the line

The graph is shown below

So for question B

We will shade above the line

Question C

The percentage of students in Brookland Middle School who are attending seventh grade is 54.54%

What is percentage?

In mathematics, a percentage is a number or ratio that is expressed as a fraction of 100. Although "pct," "pct," and occasionally "pc" are also used as abbreviations, the percent symbol "%" is most usually used to denote it. A% is a number that has no dimensions and is dimensionless (pure).

We know that, to get the value of percentage we have to divide the value for which percentage needs to be calculated by total value and then multiply the resultant by 100.

So, we will divide the number of student in seventh class by the total number of student and then multiply it with 100.

(750/1375)100 = 54.54 %

Therefore, percentage of students attending Brookland Middle School are in seventh grade is 54.54%.

The equivalent expression using a positive exponent is (5/3)⁴ .

If an expression was created utilizing integer variables, constants, and algebraic operations, it is said to be algebraic (addition, subtraction, multiplication, division and exponentiation by an exponent that is a rational number)

A positive expression is given as (3/5)⁻⁸ ÷ (3/5)⁻⁴ .

Using the properties of exponents we can calculate the expression as:

(3/5)⁻⁸⁺⁴ = (3/5)⁻⁴ = (5/3)⁴

Hence the required expression is (5/3)⁴

The length of the pole is 19.15 feet.

The angle of elevation is created by the horizontal line and the line of sight. If the line of sight is upward from the horizontal line, the angle formed is an angle of elevation.

Given:

Angle made by straight road = 15°

Angle of elevation of the sun = 57°

Length of the shadow = 75 feet

∠ACB = 90° - 57° = 33°

∠CAB = 57° - 15° = 42°

Using Sine Law to find BC i.e.length of the pole.

[tex]\frac{BC}{sin A} = \frac{AB}{sin C}[/tex]

[tex]\frac{BC}{sin 42} = \frac{75}{sin 33}[/tex]

[tex]BC= \frac{75sin 42}{sin 33}[/tex]

BC ≅ 19.15 feet (to the nearest hundredth.)

The number of months where they will both have same amount in their accounts is 40 months.

From the information given, the function f(t) = 10t + 500 models the amount of money in Abby’s account over time and the function g(t) = 11.25t + 450 models the amount of money in Lexi’s account over time.

It should be noted that the number of years when there value will be the same is:

10t + 500 = 11.25t + 450

Collect like terms

11.25t - 10t = 500 - 450

1.25t = 50

Answer:

−9 < x < −1

Step-by-step explanation:

a) Let's find the critical points of the inequality.

x^2 + 10x + 9 = 0

(x + 1)(x + 9) = 0

x + 1 = 0 or x + 9 = 0

x = −1 or x = −9

x < −9 (Wrong)

−9 < x < −1 (Correct)

x > −1 (Wrong)

Your answer is −9 < x < −1

Answer:

£20 note, £5 note, 50p,50p,50p, 5p

Step-by-step explanation:

Liam buys some fruit for £26.55 by paying 2 notes of £20 and £5 and 3 coins of 50 cent and one coin of 5 cent.

Combining objects and counting them as one big group is done through addition. In arithmetic, addition is the process of adding two or more integers together. Addends are the numbers that are added, and the sum refers to the outcome of the operation.

Given:

Liam buys some fruit for £26.55.

He pays the exact amount using two notes and four coins.

So, possible notes are £1, £5, £10 and £20.

And the possible coins are 1¢, 5¢, 10¢, 25¢, 50¢, and £1.

So, through trial and error,

we get notes of £20 and £5.

And the coins are three coins of 50 cent and 1 coin of 5 cent.

The total amount = adding the amount of notes and coins.

£26.55 =  £20 + £5 + 3(50¢) + 5¢

Therefore, notes of £20 and £5 and the coins are three coins of 50 cent and 1 coin of 5 cent, Liam used.

The scale factor for the graph will be 3 and there will be enlargement.

The scale factor may be defined as the ratio of two dimensions such that one figure is large, and another is small. The scale factor is done due to the unpractical measurement of any figure. For example, if a figure is a scale copy of the scale factor of 6/2 it means 2 is converted into 6. We can use the following points to know about enlargement.

A(1, 1) ⇒ A'(3, 3)

B(2, 1) ⇒ B'(6, 3)

C(1, 2) ⇒ C'(3, 6)

D(2, 2) ⇒ D'(6, 6)

Now, to find the scale factor, simply divide the Point' with the original Point. Use any number.

A'(3, 3)/(A(1, 1)) = 3

B'(6, 3)/(B(2, 1)) = 3

C'(3, 6)/(C(1, 2)) = 3

D'(6, 6)/(D(2, 2)) = 3

which shows that the scale factor is 3.
