What is x in these equations a) x+4= 7² - 6 b) x+ √4 + 19= 4x +9

Answer:

-8/3 + 2/3 (√3)

Where, p = -8/3

q = 2/3

Step-by-step explanation:

Simplify(1-√3)(1/3+√3)

= (1-√3)(1/3+√3)

Expand the bracket

= 1(1/3+√3) -√3(1/3+√3)

= 1/3 + √3 - √3/3 - 3

Collect like terms

= 1/3 - 3 + √3 - √3/3

= (1/3 - 3) + (√3 - √3/3)

= -8/3 + [(3√3 - √3)/3]

= -8/3 + 2√3/3

= -8/3 + 1/3( 2√3)

= -8/3 + 2/3 (√3)

Where, p = -8/3

q = 2/3

Answer:

B y is 3/4 of (x+y)

Step-by-step explanation:

a : is the same thing as a division sign or a fraction bar

so 1 : 3 = 1/3

this ratio says that for every 1 of x, there are 3 y's.

so 1x = 3y or y = 1/3x

x = 1; y = 3

x + y = 4

y / (x+y)

3 / 4

y is 3/4 of (x+y)

The ratio is 217 to 279 or 217:279 or [tex]\frac{217}{279}[/tex]

Males: The number of males if already stated. (217)

Total number of people present: The total number of people means males + females. There are 62 females and 217 males. 62+217 is 279.

Males to total people = 217 to 279

━━━━━━━━━━━━━━━ ♡ ━━━━━━━━━━━━━━━  

The ratio of the males to the total number of people present is  [tex]\frac{7}{9}[/tex] = 7:9

"A ratio is an ordered pair of numbers a and b, written [tex]\frac{a}{b}[/tex] where b does not equal 0."

We have

Female candidates at the high school rally = 62

Male candidates at the high school rally = 217

Total number of people present at the high school rally

= 279

The ratio of the males to the total number of people present

= [tex]\frac{Total Number of People Present}{Male Candidates Present}[/tex]

= [tex]\frac{217}{279}[/tex]

Answer:

Option D. 2x⁷ - 12x⁶ + 10x⁵

Step-by-step explanation:

From the question given:

Length (L) = 2x²

Width (w) = x³

Height (h) = x² - 6x + 5

Volume (V) =?

Volume (V) = length (L) x width (w) x height (h)

V = L x w x h

V = 2x² × x³ × x² - 6x + 5

V = (2x²) (x³) (x² - 6x + 5)

V = (2x⁵) (x² - 6x + 5)

Clear bracket

V = 2x⁷ - 12x⁶ + 10x⁵

Therefore, the volume of the cube is 2x⁷ - 12x⁶ + 10x⁵

Answers:

a = 2

h = 3

k = -3

You have the correct h and k values. Nice work so far.

==========================================================

Explanation:

(h,k) is the vertex. So (h,k) = (3,-3) meaning h = 3 and k = -3

To get the value of 'a', we need to plug in some point on the red graph. Each point is of the form (x,y). We can pick any point we want that isn't the vertex.

Let's pick (0,3) which is the y intercept. I'm picking this because 0 is an easy number to work with

------------

y = a|x-h| + k

y = a|x-3| + (-3) .... plug in the h,k values

y = a|x-3| - 3

3 = a|0-3| - 3 .... plug in (x,y) = (0,3)

3 = a|-3| - 3

3 = a*3 - 3

3 = 3a - 3

3a-3 = 3

3a = 3+3 ... adding 3 to both sides

3a = 6

a = 6/3 ... divide both sides by 3

a = 2

The value a = 2 indicates that the parent function y = |x| has been stretched vertically by a factor of 2. So it is twice as tall as before. Then it has been shifted to place the vertex at (3,-3) as shown in the graph.

------------

You may be wondering why you can't pick on the vertex for (x,y)

Let's see what happens if we use (x,y) = (3,-3)

y = a|x-3| - 3

-3 = a|3-3| - 3 ... plug in (x,y) = (3,-3)

-3 = a|0| - 3 ... uh oh, we get 0 here

-3 = a*0 - 3

-3 = 0 - 3

-3 = -3

We get a true statement, which is nice, but it doesn't tell us anything about what the value of 'a' is. That 'a' term goes away entirely. So I avoided using x = 3 to prevent x-3 from being 0.

Answer: Hi!

Here we're trying to find something called a unit rate. To find the unit rate in this situation, we have to divide the amount of cars by the amount of days:

99 ÷ 9 = 11

Sophia can wash 11 cars in one day.

Hope this helps!

Answer:

[tex]\Huge \boxed{\mathrm{11}}[/tex]

Step-by-step explanation:

She can wash 99 cars in 9 days.

Divide number of cars by number of days.

99 cars / 9 days ⇒ 11 cars/day ⇒ 11 cars per day.

Answer:

184/4

Step-by-step explanation:

A rational number is a number in the form p/q where the numerator and denominator (p and q) are both integers but the denominator q is not equal to zero (q ≠ 0)

An integer is a whole number (not fractional) that is either positive, negative or zero.

From the question:

-144 is an integer because it is a negative whole number. Also -144 can be represented as -144 / 1, hence it is a rational number

√218/12 is neither a rational number or integer

184/4 is not an integer because it is not a whole number. 184/4 is a rational number

99 is an integer because it is a positive whole number. Also 99 can be represented as 99 / 1, hence it is a rational number

Answer:

➨ -2x + 4 = 1 - 4x - 3

➨ -2x + 4 = -4x - 2

➨ -2x + 4x = -2 - 4

➨ 2x = -6

➨ x = -6/2

➨ x = -3

Therefore, the value of x is -3.

Answer:

C: y decreases as x increases

Step-by-step explanation:

Notice from this graph, as we move from left to right, the y values are decreasing while the x values are increasing.

This means that the relationship of the line in terms of x and y can be described as, as y decreases, x increase.  Hence you will choose option C.

You can validate this by choosing to definitive points on the line, say the origin (0,0) and (2, -6).  Notice that our x value increased, but our y value decreased.

Sum of the number is 8.4

Step-by-step explanation:

x = 8.4

Answer:

5 (x+6)=48

x=3.6

Step-by-step explanation:

let x be the unknown number :

Menjawab:

Rp. 275.000

Penjelasan langkah demi langkah:

Diberikan sebagai berikut:

Jumlah maksimal toko sepatu yang bisa menampung = 400 pasang

Jumlah maksimal sepatu pria = 150 pasang

Jumlah terkecil sepatu wanita = 150 pasang

Keuntungan sepatu pria = Rp 1000

Keuntungan sepatu wanita = Rp. 500

Karena itu, jumlah maksimum sepatu wanita:

(Toko sepatu maksimum dapat menampung - jumlah maksimum sepatu pria)

(400 - 150) = 250 pasang

Keuntungan terbesar yang bisa dicapai:

(Jumlah sepatu pria * keuntungan) + (jumlah sepatu wanita * keuntungan)

(150 * 1000) + (250 * 500)

Rp. 150.000 + Rp. 125.000

= Rp. 275.000
