Answer:

yes it is

rational number is any number that can be expressed as a ratio of two integers (hence the name "rational"). It can be written as a fraction in which the the top number (numerator) is divided by the bottom number (denominator).

Answer:

no, y=3x+3

Step-by-step explanation:

plug both points into the equations:

one works but the other doesn't so now we find a line through both points

use the formula (y_2-y_1)/(x_2-x_1) to find the slope:

y=3x+b, plug in a point to find b:

Answer:

1) -3x + 90

=(3)(30+−x)

=(3)(30)+(3)(−x)

=90−3x

=−3x+90

2) 37x+90

=40x+(3)(30)+(3)(−x)

=40x+90+−3x

Combine Like Terms:

=40x+90+−3x

=(40x+−3x)+(90)

=37x+90

3.5 Hours MARK ME AS BRAINLIEST PLEASE

Step-by-step explanation:

Take 458, and subtract 339 from it. Then, divide that by 34.

Answer:

3 and a half hours

Step-by-step explanation:

Subtract 399 from both sides

119 = 34h

Divide both sides by 34

3.5 = h

Answer:

The GCF is going to be 2

Step-by-step explanation:

This Is how I find the GCF of 3 numbers. I find the prime factorization first, then I find the common factors and multiply them. Here

The prime factorization of 8, 2 × 2 × 2 = 8

The prime factorization of 18, 2 × 3 × 3 = 18

The prime factorization of 70, 2 × 5 × 7 = 70

The one and THE only common factor is 2, which is going to be the GCF

Answer:

Step-by-step explanation:

y = 2x + 2

x = [tex]\frac{y-2}{2}[/tex]

y = [tex]\frac{x-2}{2}[/tex]

[tex]g^{-1}[/tex] (x) = [tex]\frac{x-2}{2}[/tex]

Answer:

first option

Step-by-step explanation:

congruency has its own symbol and it's a ~ top of a = sign. and the expression doesn't have the symbol. so we can eliminate two options out meaning it's a.

The correct answer would be an option (A) the measure of segment DE is equal to the measure of segment FG.

Two triangles are said to be congruent if their corresponding sides and angles are equal.

SSS stands for Side-Side-Side criterion. According to this, two triangles are congruent if three sides of a triangle are equal to the corresponding sides of the other triangle.

SAS stands for Side-Angle-Side criterion.  According to this, two triangles are congruent if the two sides and the included angle of one triangle are equal to the corresponding sides and the included angle of the other triangle.

Given that, DE = FG

Congruency is represented by its own symbol, which is a ~ sign on top.

Here, Segment FG's measure is equal to segment DE's measure.

There is no symbol assigned to the expression. Since two possibilities are no longer an option, it must be Option (A).

Hence, the measure of segment DE is equal to the measure of segment FG

Ok so 1.2 is the answer you get if you divide them

and you can also say one because its counting by ones

Answer:

120/100

Step-by-step explanation:

120÷20= 6

100÷20=5

6/5 = 1⅕

N - 72 = 36

To solve for n add 72 to both sides of the equation:

N = 108

Answer:

108

Step-by-step explanation:

Add 72+ 36 you will get your answer

The answer is 108

Therefore n= 108

Answer: x = 3.5

Step-by-step explanation:

Given

x/3 + x/7 = 5/3

Determine the Least Common Multiple (LCM) of the denominators

First 10 multiples of 3: 3, 6, 9, 12, 15, 18, 21, 24, 27, 30

First 5 multiples of 7: 7, 14, 21, 28, 35

Since 21 is the first overlapping term in both lists, therefore, 21 is the LCM of 3 and 7.

Multiply Least Common Multiple (LCM) of the denominators on both sides

21 (x/3 + x/7) = 21 × 5/3

Expand parentheses and apply the distributive property

7x + 3x = 35

Combine like terms

10x = 35

Divide 10 on both sides

10x / 10 = 35 / 10

[tex]\boxed {x=3.5}[/tex]

Hope this helps!! :)

$4000 net profit

Step-by-step explanation:

Profit adds to the net revenue, while loss subtracts from it.

So 6500 is positive but 1200 and 1300 are negative.

+6500 - 1200 - 1300 = 5300 - 1300 = 4000

$4000 profit

Answer:

Step-by-step explanation:

From what I can come up with with no actual factual information is that the equation is

[tex]\frac{1+sin^4x-cos^4x}{1-sin^6x-cos^6x}=\frac{2cos^2x}{3}[/tex] I'm going with that because it actually solves pretty easily, which is usually the way this goes. Begin by cross multiplying:

[tex]3(1+sin^4x-cos^4x)=2cos^2x(1-sin^6x-cos^6x)[/tex] and distribute:

[tex]3+3sin^4x-3cos^4x=2cos^2x-2cos^2xsin^6x-2cos^8x[/tex] and then break up the powers of sin into squared sines:

[tex]3+3[sin^2x*sin^2x]-3cos^4x=2cos^2x-2cos^2x[sin^2x*sin^2x*sin^2x]-2cos^8x[/tex]  and use the Pythagorean identity to change those sines into cosines:

[tex]3+3[(1-cos^2x)(1-cos^2x)]-3cos^4x=2cos^2x-2cos^2x[(1-cos^2c)(1-cos^2x)(1-cos^2x)]-2cos^8x[/tex]

and the FOIL out those terms inside the square brackets:

[tex]3+3[1-2cos^2x+cos^4x]-3cos^4x=2cos^2x-2cos^2x[1-3cos^2x+3cos^4x-cos^6x]-2cos^8x[/tex]

and distribute again on both sides to get rid of the brackets entirely:

[tex]3+3-6cos^2x+3cos^4x-3cos^4x=2cos^2x-2cos^2x+6cos^4x-6cos^6x+2cos^8x-2cos^8x[/tex]

and combining like terms cancels a lot of that out to leave:

[tex]6-6cos^2x=-6cos^6x+6cos^4x[/tex] and get everything on one side to factor:

[tex]0=-6cos^6x+6cos^4x+6cos^2x-6[/tex] and factor out the -6:

[tex]0=-6(cos^6x-cos^4x-cos^2x+1)[/tex] and now we'll factor by grouping, so grouping everything together to get ready for that:

[tex]0=-6[(cos^6x-cos^4x)-(cos^2x+1)][/tex] and begin the factoring:

[tex]0=6[cos^4x(cos^2x-1)-1(cos^2x-1)][/tex] and continuing the factoring:

[tex]0=-6(cos^2x-1)(cos^4x-1)\\0=-6(cos^2x-1)(cos^2x-1)(cos^2x+1)[/tex] and by the Zero Product Property (and we won't list that duplicated factor cuz it's not necessary):

[tex]cos^2x-1=0[/tex]     or       [tex]cos^2x+1=0[/tex]

Solving the first:

[tex]cos^2x=1[/tex] so

x = 0 + 2kπ  and solving the second one:

[tex]cos^2x=-1[/tex] which is not solvable over the real number system.

So x = 0 + 2kπ

and I really hope that's what you were looking for!

Answer:

3.3

Step-by-step explanation:

Find all the numbers and find the mean

The x means that there are that many of each number

1 + 1 + 2 + 3 + 3 + 4 + 4+ 5 + 5 + 5

33

We have to divide that by the total amount of numbers present

33/10 = 3.3

Answer:

Divide the numbers from within the radicals.
