Answer:

The solution to the equation is:

[tex]x=4,\:x=\frac{3}{2}[/tex]

Step-by-step explanation:

Given the equation

[tex]3\left(x-4\right)\left(2x-3\right)=0[/tex]

Using the zero factor principle

if ab=0, then a=0 or b=0 (or both a=0 and b=0)

[tex]x-4=0\quad \mathrm{or}\quad \:2x-3=0[/tex]

now solving

[tex]x - 4 = 0[/tex]

adding 4 to both sides

[tex]x - 4 + 4 = 0 + 4[/tex]

simplifying

[tex]x = 4[/tex]

and also solving

[tex]2x - 3 = 0[/tex]

adding 3 to both sides

[tex]2x - 3 + 3 = 0 + 3[/tex]

simplifying

[tex]2x = 3[/tex]

divide both sides by 2

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

simplifying

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

Therefore, the solution to the equation is:

[tex]x=4,\:x=\frac{3}{2}[/tex]

4 or 3/2

Step-by-step explanation:

I had this question on a quiz, I got it correct.

Answer:

(8, - 2 )

Step-by-step explanation:

A translation of 4 units right means add 4 to the x- coordinate

A translation of 5 units up means add 5 to the y- coordinate

(x, y ) → (x + 4, y + 5 ) ← translation rule, then

(4, - 7 ) → A'(4 + 4, - 7 + 5 ) → A'(8, - 2 )

Step-by-step explanation:

13.3 = H

9.2 = A

AH = cos

cos⁻¹(9.2÷13.3) = 46.23°

Answer:

[tex]\boxed {\boxed {\sf \angle z \approx 46 \textdegree}}[/tex]

Step-by-step explanation:

First, recall the three trigonometric ratios.

13.3 is the hypotenuse because it is opposite the right angle. 9.2 is the adjacent because it is next to angle z. We must use cosine.

First, plug the values into the cosine ratio.

Divide.

Next, use the inverse of cosine because we are trying to solve for the angle.

Round to the nearest degree. The 2 in the tenth place tells us to leave the 6 in the ones place.

Angle z is about 46 degrees

Step-by-step explanation:

15x turns into 30/2x

-4y turns into -8/2x

And finally 18 turns into 36/2

So the whole equation looks like this-

30/2x-8/2x=36/2

 P.S. I just multiplied everything by 2 and put 2 as the denominator

Answer:

x + 37 ≥ 65

Step-by-step explanation:

Given:

Money Micah wants = $65

Money Micah had = $37

Find:

Money Micah need

Computation:

Money Micah need(x)

x + 37 ≥ 65

So,

Money Micah need = 65 - 37

Money Micah need = $28

Step-by-step explanation:

3000 is the base amount of money. (1+.02) represents an increase of 2% in interest each year. (1+.02)^n-2 ; where n equals her age today. So, n-2 is the time since the money was invested, or 16.

Answer:

Pr/ok

Step-by-step explanation:

The ratio of cos P for the right-triangle PQR is PR/QR.

There are three commonly used trigonometric identities.

Sin x = 1/ cosec x

Cos x = 1/ sec x

Tan x = 1/ cot x or sin x / cos x

Cot x = cos x / sin x

We have,

Right-triangle PQR.

Answer:

19 inches

Step-by-step explanation:

Given data

The length of the subway is 855 miles.

we are told that 1 inch represents 45 miles on map

Required

we want to find the length of 855 miles in inches

Let us do the conversion from miles to inches

1 inches = 45 miles

x inches=  855 miles

cross multiply we have

x= 855/45

x= 19 inches

Hence the length on the map is 19 inches

Answer:

x=1, y=−4

Step-by-step explanation:

Divide each term by −2 and simplify.

x=−7y/2−13

7x+5y=−13

Replace all occurrences of x with −7y/2−13 in each equation.

−39y/2−91=−13

x=−7y/2−13

Solve for y in the first equation.

y=−4

x=−7y/2−13

Replace all occurrences of y with −4 in each equation.

x=1

y=−4

Answer:

step by step below

Step-by-step explanation:

(cscA+1).(1-sinA)=cosA.cotA

(1/sinA +1).(1-sinA) = 1/sinA*(1 - sinA) + 1*(1-sinA)

                             = 1/sinA - 1  + 1 - sinA

                             = 1/sinA - sinA

                             = (1 - sin²A) / sinA

                             =cos²A / sinA

                             = cosA*cosA / sinA

                             =cosA*cotA

Length of the diagonal = 1.73 cm

Step-by-step explanation:

Side of cube = 1 cm

Length of diagonal = x = ?

The formula used to find length of diagonal of cube is: [tex]Diagonal=\sqrt{3}s[/tex] where s is length of side of cube.

We have s = 1

So, Length of Diagonal will be:

[tex]Length\:of\;Diagonal=\sqrt{3}s\\Length\:of\;Diagonal=\sqrt{3}(1)\\Length\:of\;Diagonal=1.73[/tex]

So, Length of the diagonal = 1.73 cm

Answer:

The value of x is 62

Step-by-step explanation:

Given data is:

34,37,53,55,x,x+2,77,83,89and100​

As the number of values is 10 (which is even number of values) i.e. n=10

The median will be the average of two middle values.

[tex]M = \frac{1}{2}(\frac{n}{2}th\ value + \frac{n+2}{2}th\ value})\\M = \frac{1}{2}(\frac{10}{2}th\ value + \frac{10+2}{2}th\ value})\\M = \frac{1}{2}(5th\ value + 6th\ value})\\[/tex]

As it is already given that the median is 63

Putting M=63

[tex]63 = \frac{1}{2}(x+x+2)\\126 = 2x+2\\126-2 = 2x\\124 = 2x\\\frac{2x}{2} = \frac{124}{2}\\x = 62[/tex]

Hence,

The value of x is 62
