Answer:
A
Step-by-step explanation:
1) Simplify the expression
(3-4i)(1+5i)-(2-i)
2) Simplify the expression
^3√27x^6y^4
PLEASE SHOW WORK!
Answer:
21 + 12i
Step-by-step explanation:
Given
(3 - 4i)(1 + 5i) - (2 - i) expand the product of factors
= 3 + 11i - 20i² - 2 + i
= 3 + 11i + 20 - 2 + i collect like terms
= 21 + 12i
Write the equation of a line that passes the point (-6,9)and is perpendicular to a line that passes through the points (-2,1) and (6,7).
Answer: y = -(4/3)x + 1
Step-by-step explanation:
Let's start with finding an equation of a straight line (y=mx+b) that goes through points (-2,1) and (6,7).
The slope of a line, m, is the change in y for the change in x, or Rise/Run.
This is derived from the two points.
Rise (7-1) = 6
Run (6 - (-2)) = 8
Rise/Run = 6/8 or 3/4
The line is therefore y = (3/4)x + b
Find b by using one of the two points. I'll use (-2,1), but the other would also work.
y = (3/4)x + b
1 = (3/4)(-2) + b
1 = -(6/4) + b
b = 10/4
The line becomes y = (3/4)x + 10/4
--------
A line perpendicular to this will have a slope that is the negative inverse of the original line. The negative inverse of (3/4) is -(4/3).
The perpendicular line will be:
y = -(4/3)x + b
Use point (-6,9) to find b:
y = -(4/3)x + b
9 = -(4/3)*(-6) + b
9 = (24/3) + b
b = (27/3 - 24/3) = 3/3 = 1
The line is y = -(4/3)x + 1

Answer:
x+(x-50)=180
2x-50=180
2x-50+50=180+50
2x/2=230/2
x=115
Step-by-step explanation:
according to the question,
x-50+x=180°
2x-50=180°
2x=230°
x=115°.
now, for x-50° = 115°-50°= 65°

If 5x - 2y = 6 and 3x + 2y = 10, then find the value of x and y.
Step-by-step explanation:
[tex]\textsf{\large{\underline{Solution}:}}[/tex]
Given Equations:
→ 5x - 2y = 6 ----- (i)
→ 3x + 2y = 10 ---- (ii)
Adding (i) and (ii), we get:
→ 8x = 16
→ x = 16/8
→ x = 2
Substituting the value of x in (i), we get:
→ 5 × 2 - 2y = 6
→ -2y = 6 - 10
→ -2y = -4
→ y = -4/-2
→ y = 2
Therefore:
→ (x, y) = (2, 2) (Answer)
[tex]\textsf{\large{\underline{Verification}:}}[/tex]
Put x = 2 and y = 2 in first equation, the LHS becomes:
= 5 × 2 - 2 × 2
= 10 - 4
= 6
= RHS
Put x = 2 and y = 2 in second equation, the LHS becomes:
= 3 × 2 + 2 × 2
= 6 + 4
= 10
= RHS
Hence, our answer is correct (Verified)
Answer:
X= 2
Y= 2

Answer:
hi robertlyonsdamron the answer will be B
Step-by-step explanation:
You can use the order of operations to evaluate the expression. Perform the subtraction inside the parentheses: two minus three equals negative one. Evaluate the exponents: two to the sixth power is sixty-four. Multiply and divide in order from left to right: Twelve point six times negative one equals negative twelve point six, and sixty-four divided by four is sixteen. Add and subtract in order from left to right: Negative twelve point six plus sixteen equals three point four.

What is the value of a in the algebraic expression (5a+3)=52
Answer:
a= 49/5 or 9.8
Step-by-step explanation:
Answer:
49 / 5 ( or ) 9.8
Step-by-step explanation:
( 5a + 3 ) = 52
5a + 3 = 52
5a = 52 - 3
5a = 49
a = 49 / 5
( or )
a = 9.8

Which fraction is close to zero?
a. 5/12 b. 8/12 c. 2/12 d. 4/6
Answer:
2/12
Step-by-step explanation:
Answer:
C) 2/12
Step-by-step explanation:
You need to convert the fractions to decimals (by dividing the top number by the bottom number).
5/12 = 0.416...
8/12 = 0.666...
2/12 = 0.166...
4/6 = 0.666...
As you can see, 2/12 in decimal form is closer to 0 than the other fractions.

M is the midpoint of PQ. MQ=5x+8 and PQ = 6x+56, find PM
Answer:
PM = 58
Step-by-step explanation:
The question tells us that the full line has a value of 6x+56. The midpoint divides this line into equal pieces. We are also given the value of half (MQ) of the line (5x+8). By subtracting 5x+8 from 6x+56, we can figure out the value of the other half of the line (PM).
This gives us the expression for PM: x+48
Now, since these are both the two parts of the midpoint, by definition, we know they're equal.
You equal both equations and get x=10
You plug in 10 as x in the expression we got for PM (10+48), which gives us the value 58.
