If x=-5+6i and y=3-2i , then which of the following is the value of the expression 4x-y?
Answer:
Expression = -23 + 26i
Step-by-step explanation:
Given the following data;
x = -5 + 6i
y = 3 - 2i
Expression = 4x - y
Substituting the values of "x" and "y" into the equation, we have
4(-5 + 6i) - (3 - 2i)
Expanding the bracket, we have;
Expression = -20 + 24i - 3 + 2i
Expression = -23 + 26i

Answer:
The expression of the area of rectangle ABCD as simplified polynomial will be:
[tex]A=16x^2-8x[/tex]
Hence, the 2nd option is correct.
Step-by-step explanation:
As we know that the area of a rectangle can be obtained by multiplying the length by the width.
i.e.
[tex]A=l\times w[/tex]
Given
The length of a rectangle ABCD = [tex]l[/tex] = [tex](x+5) + (3x) + (4x-9)[/tex]
The width of a rectangle = [tex]w[/tex] = [tex]2x[/tex]
so the expression of the area of rectangle ABCD as simplified polynomial will be:
[tex]A=l\times w[/tex]
[tex]A=\left[\left(x+5\right)\:+\:\left(3x\right)\:+\:\left(4x-9\right)\right]\:\times \left[2x\right][/tex]
[tex]=\left(\left(x+5\right)+\left(3x\right)+\left(4x-9\right)\right)\left(2x\right)[/tex]
[tex]=\left(x+5+3x+4x-9\right)\times \:2x[/tex]
[tex]=2x\left(8x-4\right)[/tex]
[tex]=16x^2-8x[/tex]
Therefore, the expression of the area of rectangle ABCD as simplified polynomial will be:
[tex]A=16x^2-8x[/tex]
Hence, the 2nd option is correct.

Step-by-step explanation:
A plot of grass behind a building is shown.
A composite figure is shown.
The top horizontal side is labeled 16 meters. The left vertical side is labeled 8 meters and the right vertical side is labeled 16 meters. From the bottom corner of the left side, a horizontal side that is labeled 12 meters goes right. From its right end, a vertical side labeled 10 meters goes down. A line connects the bottom of this side to the bottom of the right vertical side.
What is the area of the plot of grass?

6. A total of 1,022 guests are attending a reception. If eachtable can seat
exactly 12 people, what is the LEAST number of tables needed to seat all
guests? *
Answer:
86
Step-by-step explanation:
1022/12 = 85.16666 which would mean that 85 tables would hold 12 people (1020) and 1 table would hold 2 people. So 86 tables to seat all the guests .

Which of the following decimal numbers are examples of terminating decimals?
0.6868
832.15902...
1,087.59014
9.12 5
23.7
14. 1
Answer:
First option
Sixth Option
Fifth Option
Third Option
Fourth Option
Step-by-step explanation:
Remember that a terminating decimal is a decimal that has a infinite amount of numbers after the decimal point. In this case we have 0.6868 which keeps going because it's repeating therefore it's a terminating decimal. Same rule goes for all the other options.

Answer:
Step-by-step explanation:
Miguel bikes 23km per hour and starts at mile 10. Gabby bikes 28km per hour and starts at mile 0. which system of linear equations represents this situation.
Answer:
Miguel's distance covered = 10 + 14.29 * t
Gabby's distance covered = 17.40 * t
Step-by-step explanation:
Recall that in order to convert km to miles we do:
1 km = 0.62137 mi. therefore the conversion of speeds from km to miles, so we write the distance covered for each biker in miles, we have:
23 km/h = 14.29 mi/h
and 28 km/h = 17.40 mi/h
For Miguel, the distance (D1 in miles) covered will be represented by:
D1 = 10 + 14.29 * t
where t is t the variable that represents the time in hours, and D1 is the distance covered in miles.
For Gabby the distance D2 equation is given by:
D2 = 0 + 17.40 * t

Answer: m∠5 = m∠7 = 67°
because a//b => m∠4 + m∠5 = 180°
⇔ 113° + m∠5 = 180°
⇔ m∠5 = 180 - 113 = 67°
because ∠5 and ∠7 are 2 opposing angles
=> m∠5 = m∠7 = 67°
Step-by-step explanation:
Answer:
m ∠5 = 67°m ∠7 = 67°Step-by-step explanation:
Givena║b, m ∠ 113To findm ∠5, m ∠7SolutionAngles 4 and 5 are same side interior angles and their measures add up to 180° as per definition:
m ∠ 4 + m ∠5 = 180°m ∠5 = 180 ° - m ∠4 m ∠5 = 180° - 113° = 67°Angles 5 and 7 are vertical angles and they have equal measure as per definition of vertical angles:
m ∠7 = m ∠5 = 67°Directions are on the sheet. Please help. 35 is correct btw.

i am having trouble doing this problem
Answer:
Step-by-step explanation:
A. when you multiply exponents with a common base you keep the base and add the exponents. In this case you would keep the 6 and add the -5 and 2 so the answer would be:
6^-3 which is not equivalent
B. You can distribute the exponent in to the parenthesis.
(1^5)/(6^2)^5
when you have an exponent to an exponent you mutliply. so the answer would be:
1^5/6^10
1^5 is always going to be 1 so you actually have:
1/6^10
when the exponent is on the bottom you can bring it to the top by making it negative, so the final answer for B is:
6^-10 which is equivalent
C. Same rules as B, multiply an exponent to an exponent.
6^(-5*2) = 6^-10 which is equivalent
D. When you are dividing exponents with a common base you subtract the top and bottom exponents. So in this case you have:
6^(-3-7) = 6^-10 which is equivalent
E. Using the rules from eariler the numerator can be simplified by adding the exponents.
6^5 * 6^-3 = 6^(5-3) = 6^2
which leaves you with:
6^2/6^-8
From there you can either bring the 6^-8 to the numberator to make it positive which simplifies to:
6^2 * 6^8 = 6^(2+8) = 6^10 which is not equivalent
or you can subtract the top and bottom exponents:
6^2/6^-8 = 6^(2-(-8))
the double negative cancels to a positive and you getL
6^(2+8) = 6^10 which is not equivalent
so B, C, and D are equal to 6^-10

Answer:
(A.) 0.19687 (B.) 0.82444
Step-by-step explanation:
a.
P(N=0) = 10C0(0.15)0(0.85)10 = 0.19687
b.
P(N > 1) = 1 - P(N=0) - P(N=1)
P(N=0) = 20C0(0.15)0(0.85)20 = 0.03876
P(N=1) = 20C1(0.15)1(0.85)19 = 0.1368
P(N > 1) = 1 - 0.03876 - 0.1368 = 0.82444

Dose the table represent a function?
Answer:
You can also use tables to represent functions. Instead of using two ovals with circles, a table organizes the input and output values with columns. ... Remember, a function can only assign an input value to one output value. If you see the same x-value with more than one y-value, the table does not represent a function. so yeah it does represent a function.
