Answer:

The option A) -4-3i is correct

Therefore the simplified given expression is (-1-6i)+(-3+3i)=-4-3i

Step-by-step explanation:

Given that the expression is (-1-6i)+(-3+3i)

To simplify the given expression as below :

(-1-6i)+(-3+3i)=-1-6i-3+3i

=(-1-3)+(-6i+3i) ( combining the real parts and imaginary parts separately and adding the like terms )

=-4+(-3i)

=-4-3i

(-1-6i)+(-3+3i)=-4-3i

Therefore the simplified given expression is (-1-6i)+(-3+3i)=-4-3i

Therefore the option A) -4-3i is correct

The answer that I got was side  WX = 12 inches

It says that WY is congruent to XY which means that they are the same. That means that XY is also 3m-4. It also says that the perimeter of the triangle is 76 inches.

With this information I set up an equation:

3m-4 + 3m-4 +m = 76

(The number on the right side is the perimeter given to us in the problem and the numbers on the left side are the 3 side lengths).

I combined like terms on the left side and ended up with:

7m-8=76 

I added 8 to both sides of the equation and got 7m=84.

Finally I divided both sides by 7 and got m=12

m is equivalent to side WX..

Hope this helps!

Plsss help me graph this!!! Attached is the question
e-lub [12.9K]

The graph is a straight line graph with a slope of -1/2

Equation of a line in point-slope form

The equation of a line in point slope form is expressed as:

y - y₁ = m(x - x₁)

Given the following parameters

Point = (-2, 3)

Slope = -1/2

Substitute the given parameters into the formula

y-3 = -1/2(x-(-2))

y-3 = -1/2(x+2)

Write in slope-intercept form

2(y-3) = -(x+2)

2y-2(3) = -x -2

2y - 6 = -x -2

2y = -x + 4

y = -1/2x + 2

The graph of the equation is as shown below

Priya has a recipe for banana bread. She uses 7/1/2 cups of flour to make 3 loaves of banana bread. Andre will follow the same r
wlad13 [49]

Answer:

5b=2f

Step-by-step explanation:

Priya uses 7\dfrac{1}{2} cups of floor to make 3 loaves of banana bread.

Andre will follow the same recipe. He will make b loaves of banana bread using f cups of flour.

To find the relation between b and f, the steps are as follows :

\dfrac{\text{cups of flour}}{\text{loaves of banana bread}}=\dfrac{7 \dfrac{1}{2}}{3}\\\\=\dfrac{\dfrac{15}{2}}{3}\\\\=\dfrac{15}{2}\times \dfrac{1}{3}\\\\=\dfrac{5}{2}

It means,

\dfrac{f}{b}=\dfrac{5}{2}\\\\5b=2f

So, the relationship between b and f is "5b=2f".

Sin 0= 8/17 determine the value of tan?
DiKsa [7]

Answer:

tan theta = 8/15

Step-by-step explanation:

Sin is equal to opposite over hypotenuse. So it means that the side opposite from theta is 8, and the hypotenuse is 17.

To find the value of the adjacent side from theta, use the Pythagorean Theorem.

a^2 + b^2 = c^2

8^2 + b^2 = 17^2

64 + b^2 = 289

Subtract 64.

b^2 = 225

Take the square root.

b = 15.

So that means:

the side opposite from theta is 8,

the side adjacent from theta is 15,

the hypotenuse is 17.

Now we take tan, opposite over adjacent, and use the values from the triangle.

tan = opposite / adjacent

tan = 8/15.

Question: A doctor prescribes 600 milligrams of a therapeutic drug that decays by about 13% each hour. Write an equation in base
UkoKoshka [18]

Answer: A = 600(0.87^{h})

Step-by-step explanation:

The rate = 13% = 0.13

Let I be the initial value = 600 mg

The Equation will be

A = I (1 - R%)x^{h}

A = 600( 1 - 0.13)x^{h

A = 600(0.87^{h})
