The value of x is 5 and the value of y is -13 which satisfies the equation. The correct option is C.

The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.

The given equation is,

( x + yi ) + ( 4 + 9i ) = 9 - 4i

The points are x= 5 and y = -13,

( x + yi ) + ( 4 + 9i ) = 9 - 4i

( 5 -13i ) + ( 4 + 9i ) = 9 - 4i

5 + 4 -13i+9i = 9-4i

9-4i = 9 - 4i

Therefore, the value of x is 5 and the value of y is -13 which satisfies the equation. The correct option is C.

It took a lot of space on the calculator

Answer:

a) 3,467 gallons of water

b) 17,335 ml of insecticide = 12 bottles

c) $ 42,000

Step-by-step explanation:

1 gal. Water = 3785.412 ml

1 hectare = 10,000 m^2

2.6 hectare = 2.5 x 10.000 m^2 = 26,000 m^2

(a) 4 gal. water cover 30m^2

X gal water cover 26,000 m^2

(4 x 26,000)/30 = 3,467 gal of water

(b) 5 ml per 1 gal of water

X ml per 3,467 gal of water

(5 x 3,467) = 17,335 ml of insecticide

Bottle of insecticide = 1,500 ml of insecticide in each bottle.

17,335/1,500 = 12 bottles of insecticide

(c) 12 x $3,500 = $ 42,000

Answer:

frist parentheses then subtract

The solution of equation  2(2x+3)-2 = 52(2x+3)−2 = 5 is x = -29/20.

The abbreviation PEMDAS is used to indicate the sequence of steps to be taken when resolving expressions with multiple operations. P is for "parentheses," E is for "exponents," M is for "multiplication," D is for division, A is for addition, and S is for subtraction.

The given equation:

2(2x+3)-2 = 52(2x+3)−2 = 5

Simplifying,

2(2x+3)-2 = 52(2x+3)−2 - 5

Using PEMDAS,

first, we solve the parentheses

4x+6 - 2 = 104x + 156 - 2 - 5

4x+4 = 104x + 149

104x - 4x = 4 - 149

100x = -145

x = -145/100

x = -29/20

Therefore, the value of x is  -29/20.

Step-by-step explanation:

Distribute:

7w+140+w=4

Add like terms

8w+140=4

Move constant to the right

8w=4-140

Add like terms

8w=-136

Divide both sides by 8

w=-17

Answer:

No.

Step-by-step explanation:

First solve for y:-

x - y^4 = 1

y^4 = x - 1

y = +/- (x - 1)^(1/4)

This is a one-to-many relation . For a given value of y there  2 values of x.

So this is NOT a function.

Answer:

165°

Step-by-step explanation:

x+15=180

Answer:

[tex] \\ \boxed{ \sf{x = 165 \degree}}[/tex]

Step-by-step explanation:

We know that a straight line has an angle of 180°.

Therefore,

Thus, the value of x is 165°.

Start with the small triangle on the right:

   35 + 96 + x = 180

   x = 49

Ah, you already have that.  Nice!

Now move to the biggest triangle:

   x + 77 + (35+y) = 180

but x = 49, so

   49 + 77 + 35+y = 180

   y = 19

Step-by-step explanation:

Answer:

where is it?

Step-by-step explanation:

The shape PQRS is a parallelogram

The given parameters are:

[tex]\mathbf{\angle PQR = 106}[/tex]

[tex]\mathbf{\angle QSR = 49}[/tex]

[tex]\mathbf{\angle PRS = 35}[/tex]

(a) Find QRS

This is calculated as:

[tex]\mathbf{\angle QRS = 2 \times \angle PRS }[/tex]

So, we have:

[tex]\mathbf{\angle QRS = 2 \times 35}[/tex]

[tex]\mathbf{\angle QRS = 70}[/tex]

Hence, the measure of angle QRS is 70 degrees

(b) Find PQS

This is calculated as:

[tex]\mathbf{\angle PQS = \frac 12 \times \angle PQR }[/tex]

So, we have:

[tex]\mathbf{\angle PQS = \frac 12 \times 106}[/tex]

[tex]\mathbf{\angle PQS = 53}[/tex]

Hence, the measure of angle PQS is 53 degrees

(c) Find RPS

This is calculated as:

[tex]\mathbf{\angle RPS = \angle PRQ }[/tex]

Where:

[tex]\mathbf{\angle PRQ = \angle PRS = 35}[/tex]

So, we have:

[tex]\mathbf{\angle RPS = 35}[/tex]

Hence, the measure of angle RPS is 35 degrees

(d) Find PSQ

This is calculated as:

[tex]\mathbf{\angle PSQ =\frac 12 \times \angle PQR }[/tex]

Where:

[tex]\mathbf{\angle PSQ =\frac 12 \times \angle 106}[/tex]

So, we have:

[tex]\mathbf{\angle PSQ =53}[/tex]

Hence, the measure of angle PSQ is 53 degrees
