Subtract.
(6x2 + 5) - (4x - 3)

Answer:

The page numbers are 36 and 37.

Step-by-step explanation:

n + (n + 1) = 73

2n + 1 = 73

n = (73 - 1)/2

= 72/2 = 36

Follow below steps:

The sum of the page numbers on the facing pages of a book is 73. To solve this, we need to establish that facing pages in a book are always one number apart. If we call one page number x, then the other page number is x+1 because page numbers are consecutive.

Now, we can create the equation x + (x+1) = 73 to find the value of x. Solving this equation, we get:

2x + 1 = 73

2x = 73 - 1

2x = 72

x = 72 / 2

x = 36

Since x is the lower of the two page numbers, then the pages are 36 and 37.

The value of (5.3x 10^4) (4.2x10^3) in scientific notation Option C 2.226 times 10^8

5.3×10^4  × 4.2 × 10^3

We multiply the numbers out front

5.3× 4.2 = 22.26

We add the exponents

10^(4+3) = 10^7

22.26×10^7

But we are not done yet because The number out front has to be between 1 and less than 10

Move the decimal 1 place to the left and add 1 to the exponent

2.226 × 10 ^(7+1)

=2.226×10^8.

Scientific notation is a way of writing very large or very small numbers. A number is written in scientific notation when a number between 1 and 10 is multiplied by a power of 10. For example, 650,000,000 can be written in scientific notation as 6.5 ✕ 10^8.

Scientific Notation is the expression of a number n in the form a∗10b. where a is an integer such that 1≤|a|<10. and b is an integer too. Multiplication: To multiply numbers in scientific notation, multiply the decimal numbers.

The proper format for scientific notation is a x 10^b where a is a number or decimal number such that the absolute value of a is greater than or equal to one and less than ten or, 1 ≤ |a| < 10. b is the power of 10 required so that the scientific notation is mathematically equivalent to the original number.

Answer:

12.75 oz

Step-by-step explanation:

1 gallon is equivalent to 64 oz.

Writing and solving an equation of ratios, we get:

 1.5 oz       1 gal

----------- = ------------

     x          8.5 gal

Here we must cross-multiply to solve for x.

x(1 gal) = (1.5 oz)(8.5 gal) = 12.75 oz

Thus, x = 12.75 oz of cleaning product must be added to 8.5 gal of water to create the desired solution.

To make an all-purpose cleaner, you need 12.75 ounces of cleaner for 8.5 gallons of water.

This is determined by multiplying the ratio of 1.5 ounces per gallon by 8.5 gallons.

follow these steps:

Therefore, 12.75 ounces of cleaner will be added to 8.5 gallons of water.

Answer:

The fraction = 9/35

To find the fraction, calculate the sum of 5 1/3 and 6 1/3, which is 35/3, then divide the final product, 3, by this sum. The fraction that when multiplied by the sum equals 3 is 9/35.

The question asks us to find the fraction when the product of the fraction and the sum of 5 1/3 and 6 1/3 is 3.

First, let's calculate the sum of 5 1/3 and 6 1/3:

5 1/3 can be written as (5*3 + 1)/3 = 16/3.

6 1/3 can be written as (6*3 + 1)/3 = 19/3.

Adding these fractions, we get (16/3) + (19/3) = (35/3).

So, we have the equation:

Fraction  imes (35/3) = 3

To find the unknown fraction, we divide both sides by 35/3:

Fraction = 3 / (35/3) = 3  imes (3/35) = 9/35

Therefore, the fraction we are looking for is 9/35.

Answer: Inconsistent.

Step-by-step explanation:

The  equation of the line in Slope-Intercept form is:

[tex]y=mx+b[/tex]

Where "m" is the slope and "b" is the y-intercept.

Solve for "y" in each equation:

Equation 1

[tex] x=-5-y\\\\y=-x-5[/tex]

Equation 2

[tex]4+y=-x+3\\\\y=-x+3-4\\\\y=-x-1[/tex]

Answer: X+5

Step-by-step explanation:

When you take out the 9 it should be 9(x+5) and when you take out the 9x on the bottom it gives you (x+5)+20 therefore x+5 is your GCF.

I hope this helps :)

The greatest common factor (GCF) of the numerator 9x+45 and the denominator x^2 +9x+20 of the provided rational expression is x+5.

The greatest common factor (GCF) is found by factoring both the numerator and the denominator and then identifying the largest factor that appears in both. For the provided rational expression 9x+45 over x2 +9x+20, let's factor both parts:

Comparing both factored forms, we can see that x+5 appears in both the numerator and the denominator, and it is the largest factor common to both. Therefore, the GCF of the numerator and the denominator is x+5.

Answer:

x = 0; x = 5

Step-by-step explanation:

2x² = 10x

2x² - 10x = 0

2x(x - 5) = 0

x = 0; x = 5

Answer:

The values of x for which it is true that  [tex]2x^2=10x[/tex]  are:

[tex]x = 0[/tex] and [tex]x = 5[/tex]

Step-by-step explanation:

We have the following equation

[tex]2x^2=10x[/tex]

To solve the equation subtract 10x on both sides of the equation

[tex]2x^2-10x=10x-10x[/tex]

[tex]2x^2-10x=0[/tex]

Now take the variable x as a common factor

[tex]2x(x-5)=0[/tex]

Then the equation is equal to 0 when x = 0 or when x = 5

[tex]x = 0[/tex] and [tex]x = 5[/tex]

Answer:

B and C

Step-by-step explanation:

The denominator of the rational expression cannot be zero as this would make it undefined.

Equating the denominator to zero and solving gives the values that x cannot be.

solve

3x² - 75 = 0 ( add 75 to both sides )

3x² = 75 ( divide both sides by 3 )

x² = 25 ( take the square root of both sides )

x = ± [tex]\sqrt{25}[/tex] = ± 5 → B and C

Answer:

Frequency = [tex]\frac{1}{2}[/tex]

Step-by-step explanation:

We are given the following function and we are to find its frequency:

[tex]f (x) = 3 cos (\pi x) -2[/tex]

We know that the standard form of cosine function is [tex]y=Acos (Bx)+c[/tex]

where [tex]A[/tex] is the amplitude, [tex]B=\frac{2\pi}{\text{Period}}[/tex] while [tex]c[/tex] is the mid line.

Frequency is given by:

[tex]F=\frac{1}{P}[/tex] where [tex]F[/tex] is frequency and [tex]P[/tex] is the period.

Finding period by comparing the given function:

[tex]y=3cos(\pi x)-2[/tex]

[tex]Period - B = \pi[/tex]

Substituting B to get:

[tex]\pi =\frac{2\pi}{\text{Period}}[/tex]

[tex]\text{Period}=\frac{2\pi}{\pi}=2[/tex]

So, Period = 2.

Since frequency is [tex]\frac{1}{P}[/tex], therefore

Frequency = [tex]\frac{1}{2}[/tex]

The frequency is T / (2π).

To find the frequency of the function f(x) = 3 cos(T x) – 2, start by recognizing the standard form of a cosine function, which is f(x) = A cos(Bx + C) + D. Here, A, B, C, and D are constants with specific roles.

        f = ω / (2π)

        f = T / (2π)

Therefore, the frequency of the function f(x) = 3 cos(Tx) – 2 is T / (2π).

Answer:

cos46°

Step-by-step explanation:

Using the co function identity

sin x° = cos(90 - x)°, hence

sin44° = cos(90 - 44)° = cos46°

Answer:  The correct option is (b) cos 46°.

Step-by-step explanation:  Given that when solving for x, the sine of 44º is used.

We are to select the other angle and trigonometric function that could be used to solve for x.

We know that,

the sine of any acute angle is equal to the cosine of its complement.

That is,

if y denotes the measure of any acute angle, then we have

[tex]\sin y=\cos(90^\circ-y).[/tex]

Therefore, if y = 44°, then we get

[tex]\sin 44^\circ=\cos(90^\circ-44^\circ)=\cos 46^\circ.[/tex]

Thus, the other angle and the  trigonometric function that could be used to solve for x is cos 46°.

Option (b) is CORRECT.
