-2/3 x - 1 =19 yeah its -2over3 with x to the right then -1 = 19

Answer:

let's start.

Step-by-step explanation:

                         [tex]\frac{(1+tanx)}{sinx} -secx = cscx\\[/tex]

we can write it as

                        [tex]\frac{(1 + tanx)}{sinx} = cscx + secx[/tex]

starting with left hand side

LHS    

       [tex]\frac{(1 + tanx)}{sinx}[/tex]

      [tex]\frac{1}{sinx} + \frac{tanx}{sinx}\\\\cscx + tanx *\frac{1}{sinx}\\\\cscx + \frac{sinx}{cosx} *\frac{1}{sinx}\\\\cscx + \frac{1}{cosx}\\\\cscx + secx[/tex]  

∴ LHS = RHS

hence,   proved

Answer:

25 phone calls

Step-by-step explanation:

Create a proportion where x is the number of phone calls for 50 minutes on the phone:

[tex]\frac{34}{17}[/tex] = [tex]\frac{50}{x}[/tex]

Cross multiply and solve for x:

34x = 850

x = 25

So, Nick would have to make 25 phone calls

Answer:

Y = 1.25x - 20

Step-by-step explanation:

Everytime she rides the bus 1.25 is taken away from that 20.

The x = Every ride

For example

say she rode the bus 5 times so it would be

1.25 × 5 = 6.25 now you take the answer and subtract it from the 20

20 - 6.25 = 13.75

? = 180 - 150 = 30

Answer:

30°

Step-by-step explanation:

The line is 180 degrees so all you have to do is subtract 150° from 180°

You should end up with 30°

Whenever you see a straight line (IT HAS TO BE STRAIGHT), it is equal to 180°.

Answer:

48cm²

Step-by-step explanation:

If the area A of a triangle varies jointly as the base b and the altitude h of the triangle, this is expressed as;

A = kbh

k is the constant of proportionality

If A  = 70cm², b = 14cm and h = 10cm

Substitute

70 = k(14)(10)

70 = 140k

k = 70/140

k = 0.5

To get the area if base is  8 cm and the altitude is 12 cm;

A = 0.5*8*12

A = ​48cm²

Hence the required area is 48cm²

Answer:

Pie is forever but the first 3 numbers re 314

Step-by-step explanation:

Answer:

Given that,

Height of dougal is 1.84 meters and height of seb is 1.7 meters. We need to find the height of dougal as a fraction of the height of seb.

Let x is height of dougal as a fraction of the height of seb. So,

If we divide 1.7 on both sides of above equation, then,

On removing decimal, we get,

Hence, this is the required solution.

Answer: p=7/2=3.5

Step-by-step explanation:

Given

-4p+9=-5

Subtract 9 on both sides

-4p+9-9=-5-9

-4p=-14

Divide -4 on both sides

-4p/-4=-14/-4

p=7/2=3.5

Answer:

x = 2

Explanation:

according to BPT theorem,

BD BE

---- = ----

DA EC

6 x+1

--- = ----

4 x

6x = 4x +4 ( cross multiplication)

transposing,

6x -4x=4

2x= 4

x= 2

hence x=2

BE = x+1 =2+1 =3

EC = x =2

Answer:

56x² - 120x + 16 ; (9x - 5)² - (5x - 3)²

x in both equations is 5

Step-by-step explanation:

Painting 1 : 81x^2 - 90x + 25

Painting 2 : 25x^2 + 30x + 9

Expression for the difference between the two paintings :

Painting 1 - painting 2

(81x^2 - 90x + 25) - (25x^2 + 30x + 9)

81x^2 - 90x + 25 - 25x^2 - 30x - 9

81x² - 25x² - 90x - 30x + 25 - 9

56x² - 120x + 16

2.)

81x^2 - 90x + 25 = 1600in²

25x^2 + 30x + 9 = 484 in²

Factorizing each equation :

81x^2 - 90x + 25 = 1600 in²

(9x - 5)^2 = 1600 in²

25x^2 + 30x + 9 = 484 in²

(5x - 3)^2 = 484

(9x - 5)² - (5x - 3)²

2.)

(9x - 5)^2 = 1600

Take square root of both sides

9x - 5 = 40

9x = 40 + 5

9x = 45

x = 45/9

x = 5

(5x - 3)^2 = 484

Take square root of both sides

5x - 3 = 22

5x = 22 + 3

5x = 25

x = 25/5

x = 5

Answer: x = 3

Answer:

A. g(x) = - x²

Step-by-step explanation:

f(x) reflex over x-axis: g(x) = - f(x)

Using translation concepts, it is found that the equation of g(x) is given by:

A. g(x) = -x².

A translation is represented by a change in the function graph, according to operations such as multiplication or sum/subtraction in it's definition.

In this problem, the parent function f(x) = x² was reflected over the x-axis, that is, it was multiplied by -1, hence the equation for g(x) is given by:

g(x) = -f(x) = -x².

Which means that option A is correct.
