x = -29/7

Step-by-step explanation:

A(x) = (x^2 + 5x + 6)(x + 5) - (x^2 + 3x - 4)(x + 7)

= (x^3 + 10x^2 + 31x + 30) - (x^3 + 10x^2 + 17x - 28) = 14x + 58

A(x) = 0 => 14x + 58 =0 => x = -58/14 = -29/7

Answer:

200.96 yd^2

Step-by-step explanation:

Area of a circle = πr^2 where r = radius

radius = diameter/2

radius = 16/2

radius = 8

Area = π(8)^2

Area = π64

Area = 200.96 yd^2
area = 3.14r^2
16 yd / 2 = r = 8

area = 3.14(8)^2
= 3.14(64)
= 200.96 yd^2

Joseph said that a rhombus with side lengths of 6 meters and a height of 4 meters has the same area as a parallelogram with a base of 12 meters and a height of 2 meters. Is he correct? Critique Joseph's reasoning. help plzz​

Answers

Answer:

Area(s) of both rhombus and parallelogram are equal at 24 meters squared. Therefore Joseph had the correct reasoning in regards to area(s) of both rhombus and parallelogram are equal at 24 meters squared.

Step-by-step explanation:

To equate area of the rhombus, multiply the side length and height of rhombus in meters. (6 meters×4 meters=Area of 24 m°2). Area of parallelogram = (12meters ×2 meters= 24 m°2. Area(s) of both rhombus and parallelogram are equal at 24 meters squared. therefore

​

Answers

Answer:

C...11 manicure X cost of each manicure

46.75 is her tips

total is 11x+46.75

Answer: y= 11x+46.75

Step-by-step explanation:

We know that Kelly did 11 manicures, we don't know how much each manicure costs so we will say that each manicure costs x amount of dollars. If Kelly receives $46.75 in tips and we need to figure out how much she made in total, we add together the tip amount and the cost of the 11 manicures. Which should look like, 11x+46.75=y

(Name all sets to which each value belongs. Rational, irrational, whole or natural.

Answers

Answer:

Step-by-step explanation:

The natural numbers, whole numbers, and integers are all subsets of rational numbers. In other words, an irrational number is a number that can not be written as one integer over another.

Moderators i have not copied this ans

Real number is the set of all numbers, including all rational and irrational numbers. Any number that we can think of, except complex numbers, is a real number. Explanation: The set of real numbers, which is denoted by R, is the union of the set of rational numbers (Q) and the set of irrational numbers (Q').

..? ⬇️

The natural (or counting) numbers are 1,2,3,4,5,
1
,
2
,
3
,
4
,
5
,
etc. There are infinitely many natural numbers. The set of natural numbers, {1,2,3,4,5,...}
{
1
,
2
,
3
,
4
,
5
,
...
}
, is sometimes written N
N
for short.

The whole numbers are the natural numbers together with 0
0
.

(Note: a few textbooks disagree and say the natural numbers include 0
0
.)

The sum of any two natural numbers is also a natural number (for example, 4+2000=2004
4
+
2000
=
2004
), and the product of any two natural numbers is a natural number (4×2000=8000
4
×
2000
=
8000
). This is not true for subtraction and division, though.

The rational numbers are those numbers which can be expressed as a ratio between two integers. For example, the fractions 13
1
3
and −11118
−
1111
8
are both rational numbers. All the integers are included in the rational numbers, since any integer z
z
can be written as the ratio z1
z
1
.

All decimals which terminate are rational numbers (since 8.27
8.27
can be written as 827100
827
100
.) Decimals which have a repeating pattern after some point are also rationals: for example,

0.0833333....=112
0.0833333....
=
1
12
.

The set of rational numbers is closed under all four basic operations, that is, given any two rational numbers, their sum, difference, product, and quotient is also a rational number (as long as we don't divide by 0
0
).

An irrational number is a number that cannot be written as a ratio (or fraction). In decimal form, it never ends or repeats. The ancient Greeks discovered that not all numbers are rational; there are equations that cannot be solved using ratios of integers.

The first such equation to be studied was 2=x2
2
=
x
2
. What number times itself equals 2
2
?

2‾√
2
is about 1.414
1.414
, because 1.4142=1.999396
1.414
2
=
1.999396
, which is close to 2
2
. But you'll never hit exactly by squaring a fraction (or terminating decimal). The square root of 2
2
is an irrational number, meaning its decimal equivalent goes on forever, with no repeating pattern:

2‾√=1.41421356237309...
2
=
1.41421356237309...

Other famous irrational numbers are the golden ratio, a number with great importance to biology:

1+5√2=1.61803398874989...
1
+
5
2
=
1.61803398874989...

π
(pi), the ratio of the circumference of a circle to its diameter:

π=3.14159265358979...
π

3.14159265358979...

and e
e
, the most important number in calculus:

e=2.71828182845904...
e
=
2.71828182845904...

Irrational numbers can be further subdivided into algebraic numbers, which are the solutions of some polynomial equation (like 2‾√
2
and the golden ratio), and transcendental numbers, which are not the solutions of any polynomial equation. π
π
and e
e
are both transcendental.

The real numbers is the set of numbers containing all of the rational numbers and all of the irrational numbers. The real numbers are “all the numbers” on the number line. There are infinitely many real numbers just as there are infinitely many numbers in each of the other sets of numbers. But, it can be proved that the infinity of the real numbers is a bigger infinity.

The "smaller", or countable infinity of the integers and rationals is sometimes called ℵ0
ℵ
0
(alef-naught), and the uncountable infinity of the reals is called ℵ1
ℵ
1
(alef-one).

There are even "bigger" infinities, but you should take a set theory class for that!

Where do the slope and y-intercept show up in the tables and graphs?

Answers

Answer:

Solution: The general form of the line on a graph is y = mx+c,

where y is the coordinate of the point along the y-axis,

x is the coordinate of the point along the x-axis,

m is the slope of the line or arc tan of the angle the line makes with the x-axis, and

c is the intercept the line makes on the y-axis.

Suppose we want a line having a slope of 45º with the x-axis and passes through point P (4,6), the equation of the line is

y = mx + c
