Answer:

[tex]x < 2 \frac{2}{3} [/tex]

Step-by-step explanation:

The symbol for greater than is '>'.

-3x +6 > -2

Bring constants to one side:

-3x > -6 -2

Simplify:

-3x > -8

Divide both sides by -1, change sign:

3x < 8

Divide by 3 on both sides:

Step-by-step explanation:

Answer:

x = 8 or -4

Step-by-step explanation:

6(x - 2)² + 7 = 223

PEMDAS

expand (x - 2)² first using FOIL

(x - 2)(x - 2)

x² - 2x - 2x + 4

x² - 4x + 4

rewrite equation

6(x² - 4x + 4) + 7 = 223

distribute the 6 through the parentheses

6x² - 24x + 24

rewrite equation

6x² - 24x + 24 + 7 = 223

combine like terms

6x² - 24x + 31 = 223

subtract both sides by 223

6x² - 24x - 192 = 0

divide both sides by 6

x² - 4x - 32 = 0

factor with factoring X

x² - 8x + 4x - 32 = 0

factor by grouping

(x² - 8x) + (4x - 32) = 0

x(x - 8) +4 (x - 8) = 0

(x - 8)(x + 4) = 0

x = 8 or -4

[tex]\mathbf{\iiint_W (x^2+y^2) \ dx \ dy \ dz = \dfrac{2}{15}}[/tex]

Step-by-step explanation:

Given that:

where;

the top vertex = (0,0,1) and the  base vertices at (0, 0, 0), (1, 0, 0), (0, 1, 0), and (1, 1, 0)

As such , the region of the bounds of the pyramid is: (0 ≤ x ≤ 1-z, 0 ≤ y ≤ 1-z, 0 ≤ z ≤ 1)

[tex]\iiint_W (x^2+y^2) \ dx \ dy \ dz = \int ^1_0 \int ^{1-z}_0 \int ^{1-z}_0 (x^2+y^2) \ dx \ dy \ dz[/tex]

[tex]\iiint_W (x^2+y^2) \ dx \ dy \ dz = \int ^1_0 \ dz \ ( \dfrac{(1-z)^3}{3} \ y + \dfrac {(1-z)y^3)}{3}] ^{1-x}_{0}[/tex]

[tex]\iiint_W (x^2+y^2) \ dx \ dy \ dz = \int ^1_0 \ dz \ ( \dfrac{(1-z)^4}{3}+ \dfrac{(1-z)^4}{3}) \ dz[/tex]

[tex]\iiint_W (x^2+y^2) \ dx \ dy \ dz =\dfrac{2}{3} \int^1_0 (1-z)^4 \ dz[/tex]

[tex]\iiint_W (x^2+y^2) \ dx \ dy \ dz =- \dfrac{2}{15}(1-z)^5|^1_0[/tex]

2nd: 1/8

3rd: I don't know anything about inchwe study in cm so I don't know the answer

Step-by-step explanation:

we throw a coin. it has 2 probabilities: heads or tails

each probability is 1/2

1st throw 1/2

2nd throw 1/2

3rd throw 1/2

as all these throws are independent from one another, we put × between them. so: 1/2 ×1/2 ×1/2= 1/8

x= 3.89 x 7.9

Step-by-step explanation:

x= 3.89 x 7.9

x=30.731

Answer: (8)($4)

Answer with an explanation:

What we need to know: Any number 5 or higher is automatically rounded up, any number 4 or lower is automatically round down. Also if the number is after the decimal you can say 5 or higher with a zero because it doesnt do anything to the number, so you could say .50 or higher or .40 or lower and if it has three decimal places just add another zero so it would be .500 higher or .400 lower.

So, 7.9 is rounded up to 8.0 because 9 is 5 or higher.

$3.89 is rounded up to $4.00 because .89 is higher than .50.

Now just take off the zeros from 8.0 and $4.00 to get (8)($4)

Answer:

[tex]7x^2 - 3y + 9[/tex]

Step-by-step explanation:

Hey there!

Well to solve the given,

2y - y + 7 - 1 + 3 + 7x^2 - 4y

We need to combine like terms

[tex]2y - y + 7 - 1 + 3 + 7x^2 - 4y\\7x^2 - 3y + 9\\[/tex]

Hope this helps :)

Answer:

7x^2 - 3y + 9

Step-by-step explanation:

   2y - y + 7 - 1 + 3 + 7x^2 - 4y          [Combine like terms]

= (2y - y - 4y) + (7- 1 + 3) + 7x^2

= -3y + 9 + 7x^2                 [Order the terms from most exponents to least]

= 7x^2 - 3y + 9

Answer:

Susan has a total of 660 nails

Step-by-step explanation:

John box contains 65 small nails, 40 medium nails, and 45 large nails.

The proportion of John nails is

65/5:40/5:45/5

13:8:9

Total = 30

If Susan has 176 medium nails and same proportion to John's nails

8/30(x) = 176

Where x is the total number of nails for Susan box

X= (176*30)/8

X= 22*30

X= 660 nails

Susan has a total of 660 nails

Answer:

Step-by-step explanation:

If n=1 then 32n+7=16=2(8) so true when n=1

Assume true for n=k so

8|32k+7

If n=k+1

32(k+1)+7

32k+2+7

If 32n+7 is divisble by 8 then 32n+7=8A where A∈Z, and thus 32k+2+7=8B where B∈Z

32×32k+7

32×(8A)=72A

72A=8(9A)=9B

So by induction 32n+7 is divisibe by 8 ∀n∈N

Answer:

$3050.48

Step-by-step explanation:

If 4% is compounded quarterly, that means it's 1% every quarter. since we have 5 years, that's 1.01^20, which is approx. 1.2202. We multiply this by the orignal $2500, so our investment at the end of 5 years is $3050.48 (rounded to nearest cent)

The amount of money that Tia's investment would be worth at the end of 5 years is equal to $3050.5.

Given the following data:

To determine how much is the investment worth at the end of 5 years:

Mathematically, compound interest is given by the formula:

[tex]A = P(1 + \frac{r}{n})^{nt}[/tex]

Where;

Substituting the given parameters into the formula, we have;

[tex]A = 2500(1 + \frac{0.04}{4})^{4\times 5}\\\\A = 2500(1 +0.01)^{20}\\\\A = 2500(1.01)^{20}\\\\A = 2500(1.2202)[/tex]

Future value, A = $3050.5

Answer:

Commutative Property

Step-by-step explanation:

Additive Identity: If you add a real number to zero or add zero to a real number, then you get the same real number back.

Additive Inverse: When you add the same number but reversed sign, you get 0.

Commutative Property: a + b = b + a

Addition distributive property: a(b+ c) = ab + ac.

In this case, we use the commutative property:

27 + 15 + 3 + 5 = 27 + 3 + 15 + 5.

We know that 27 + 3 = 30 and 15 + 5 = 20, so we get 50 quickly using mental math.
