Answer:

The answer is (C) \frac{2}{3}+\frac{17}{2}i

Step-by-step explanation:

∵ \frac{2}{3}+6i+\frac{5}{2}i = \frac{2}{3}+\frac{12}{2}i+\frac{5}{2}i=

                                                  = \frac{2}{3}+\frac{17}{2}i

∴ The answer is \frac{2}{3}+\frac{17}{2}i in standard form

Answer:

Choice C is the answer.

Step-by-step explanation:

We have given an expression.

(\frac{2}{3} +6i)+(\frac{5}{2}i)

We have to simplify it and write it as complex number in standard form.

a+bi is a complex number in standard form.

\frac{2}{3}+6i+\frac{5}{2}i

Adding like terms, we have

\frac{2}{3} + (6+\frac{5}{2})i

\frac{2}{3} +(\frac{12+5}{2})i

\frac{2}{3}+(\frac{17}{2})i

\frac{2}{3}+\frac{17}{2}i which is the answer.

Claire is 2 year younger than her sister. The
natta225 [31]

Given:

Claire is 2 year younger than her sister.

The  sum of ages is no less than 44 years.

To find:

Inequality and find the youngest age Claire can  be.

Solution:

Let the age of Claire be x.

Her sister's age = x+2

Sum of their ages is no less than 44 years. It means the sum ages is greater than or equal to 44.

x+(x+2)\geq 44

2x+2\geq 44

2x\geq 44-2

2x\geq 42

Divide both sides by 2.

x\geq 21

It means, Claire age can be greater than or equal to 21. So, the youngest age Claire can  be 21 years old.

Therefore, the required inequality is  2x+2\geq 44 and the correct option is B.

How do you do this math
Basile [38]

Answer: y = -3x - 6

Step-by-step explanation:

One way to write a <u>linear equation</u> is with slope-intercept form.               Slope-intercept form is y = mx + b, where m is the slope, and b is the              y-intercept.

Thus, the equation is y = -3x - 6

Hope it helps :) and let me know if you are confused anywhere.

Can someone help me with these questions? i’m so lost
spayn [35]

Answer:

Q.5 ab=cd

Q.6 ad=bc

Q.7 ce=ae

Q.8 eb=ed

Q.9 angle D=angle B (opposite angle of parallelogram are equal)

let other angle of parallelogram be x.

angle A+angle B +angle C + angle D= 360° (sum of quadrilateral is 360°)

x+130°+x+130°=360°

2x+260°=360°

2x=360°-260°

2x=100°

x=100/2

x=50°

Q.10 similarly, angle b= angle d

let other angle be x.

x+61°+ x+61°=360°

2x+122°=360°

2x=360°+122°

2x=238°

x=238°/2

x=119°

Q.11 in quadrilateral opposite angles are equal and opposite angle of parallelogram are equal.

Q.12 in quadrilateral opposite angle are equal and opposite angle of parallelogram are equal.

Q.13 in quadrilateral opposite sides are equal and opposite sides are parellel and this property is also present in parallelogram.

q.14 in quadrilateral diagonal bisected each other and diagonal of parallelogram also bisect each other.
