Answer:

x < -1

Step-by-step explanation:

9 -10 > x

x< -1

Answer:

x < - 1

Step-by-step explanation:

9 - x > 10 ( subtract 9 from both sides )

- x > 1

multiply both sides by - 1, reversing the symbol as a result of multiplying by a negative value.

x < - 1

Answer:

a=57 b=62

Step-by-step explanation:

u⁰=52

u¹=a

u²=b

u³=67

Use the explicit relation given by:

u(n)=u⁰+nd

where n is any term and d is the common difference.

u³=u⁰+3d

67=52+3d

3d=67-52

d=15/3

d=5

a=52+5=57

b=a+5=62

67=b+52=62+5=67 (just to make sure of the answer)

Hello.

In order to solve a proportion, you should cross-multiply:

[tex]\displaystyle\frac{7}{x} =\frac{5}{9}[/tex]

Multiply 7 times 9 and 5 times x:

5x=63

Divide both sides by 5:

x=[tex]\displaystyle\frac{63}{5}[/tex]

Now let's solve the second proportion.

Multiply 8p times 6 and 12 times 15:

48p=180

Divide both sides by 48:

p=3.75

I hope it helps.

Have an outstanding day.

After nine weeks Amir would have enough to buy the MP3

It will take Amir 9 weeks to save enough money for the MP3 player

Answer:

-3

Step-by-step explanation:

4(2a +3)<3(a - 1)

8a +12 <3a - 3

8a - 3a <-3 - 12

5a<-15

a<15 :5

a<-3

Answer:

Step-by-step explanation:

4(2a+3) =3(a-1)

simplify

8a+12 =3a-3

-12 on the 12 and -3

8a=3a-15

add 15 to the 15 and 8

13=3a

always divide by the variable so 3 divide by 3 and 3 divide by 13

A= 4.3

Answer:

It's B

Step-by-step explanation:

Multiple the denominator with the whole number, then take that number and add it with the numerator. So you'll have 12/5 x 19/4. Multiply the numerators with each other and the denominators with each other and you'll have 228/20. Divide 228 by 4 and you'll get 11 2/5.

Answer:

Step-by-step explanation: Jordan's batches have 18 muffins a piece he made 7 bathes so 7 times 18 equals 126 muffins. Raj's batches have 15 muffins per batch which he also makes 7 batches of so 7 times 15 is 105. The boys then add all their muffins together so 126 muffins plus 105 muffins is 231 muffins. They then have to divide the muffins into boxes that can hold up to 6 muffins each so  you are dividing 231 divided by 6 so the answer is 38 full boxes and 3 muffins left in the last box ( I just took the test and that was the answer)

Answer:

53

Step-by-step explanation:

We can use the Pythagorean Theorem to find x.

Pythagorean Theorem:

[tex]a^2+b^2=c^2[/tex]

Where "a" and "b" represent the legs and "c" represents the hypotenuse of the right triangle.

Let's substitute the given lengths into the equation:

[tex]28^2+45^2=x^2\\784+2025=x^2\\x^2=2809[/tex]

Take the square root of both sides:

[tex]\sqrt{x^2}=\sqrt{2809}[/tex]

[tex]x=53[/tex]

Answer:

y-3=3(x-4)

Step-by-step explanation:

Hi there!

We are given that a line intersects the points (4, 3), and (6, 9)

The slope of this line is 3

And we want to write an equation in point-slope form using (4, 3)

Point-slope form is written as [tex]y-y_1=m(x-x_1)[/tex], where m is the slope and [tex](x_1, y_1)[/tex] is a point

We already have one point of the equation filled out -- the [tex]y_1[/tex], which in this case, is 3;

Our current equation is:
[tex]y-3=m(x-x_1)[/tex] (n.b. I put m and [tex]x_1[/tex] as place holders)

Before we proceed though, let's label the values of the other things (m and [tex]x_1[/tex]) to avoid confusion:
[tex]x_1=4\\m=3[/tex]

Now we can substitute these into the equation:

y-3=3(x-4)

Hope this helps!

Answer

Step-by-step explanation:

Question is not clear. Is 4y being divided only by 7z or is the whole expression (3x - 4y)?

Answer:

D, it admits 4 complex roots

Step-by-step explanation:

Based on what you've written;

f(x) can be rewritten by adding the light terms together as;

f(x)=2x⁴-16x+1768.68

By graphing this function on an app, since i cannot possibly simplify this equation or use a calculator;

we observe that this function does not intersect the x-axis at any point, hence it does not admit any real roots.

So your answer must be D.

ps: Regardless if you forgot any x's in your equation and if f(x) was actually defined by,

f(x)=2x⁴-9.32x³+1772x²-16x+6

This equation also admits 4 complex roots and does not intersect the x-axis

n= the first integer

n + (n+1) + (n+2) + (n+3) + (n+4) + (n+5) = 519

6n + 15 = 519

6n = 594

n = 99

1st one = 99

so 3rd one = 101

The approximate loudness of a rock concert with a sound intensity of 10⁻⁹ is 110 Db.

Logarithms are another way of writing exponent. A logarithm with a number base is equal to the other number. It is just the opposite of the exponent function.

The loudness (L) measured in decibels (Db), of sound intensity (I), measured in watts per square meter, is defined as

[tex]\rm L = 10 \ log \ \dfrac{I}{I_o}[/tex]

where [tex]\rm I_o = 10^{-12}[/tex] and is the least intense sound a human ear can hear.

The approximate loudness of a rock concert with a sound intensity of 10⁻¹ will be

[tex]\rm L = 10 \ log \ \dfrac{10^-^1}{10^{-12}}\\\\\rm L = 10 \ log 10^1^1\\\\L = 10*11\\\\L = 110[/tex]

The approximate loudness of a rock concert with a sound intensity of 10⁻¹ is 110 Db.
