k=1/3 and k=3/2 which line would be steeper
Answer:
k = 3/2
Step-by-step explanation:
assuming k is your slope
rise/run = y/x
k = 1/3 therefore, (3,1) is your (x,y) points
k=3/2 therefore, (2,3) is your (x,y) points
as you can see, you move 2 more units up on the y-axis with k =3/2. Therefore, it is steeper.

Triangle ABC has vertices at A (1,-3), B (3,0)x and C (5,-3). What is the distance from vertex B to the midpoint of AC?
Answer:
The distance from vertex B to the midpoint of AC is 3 units
Step-by-step explanation:
we are given a triangle with vertices A (1,-3), B (3,0) and C (5,-3).
Mid point of of AC (x,y) = ( 1+5/2 , -3 -3/2)
= ( 6/2 , -6/2)
= (3 , -3)
Distance formula = [tex]\sqrt{(x2 - x1)^2 + (y2 - y1)^2}[/tex]
= [tex]\sqrt{(3-3)^2 + (0 + 3) ^2}[/tex]
= [tex]\sqrt{(3)^2}[/tex]
= 3 units

The subject of the formula below is y
y=4x+3
Rearrange the formula to make x the subject
Answer:
x = (y - 3)/4.
Step-by-step explanation:
y = 4x + 3
y - 3 = 4x
x = (y - 3)/4.
Step-by-step explanation:
y=4x+3
all divide by 3
4x=y/3
cross multiple
12x=y
divide both sides by 12
therefore, x is equal to y/12
A backpack is on sale for 30% off. If the sale price is $15.75, what is the original price to the nearest cent?
Answer:
$22.50
Step-by-step explanation:
As it is 30% off, $15.75 is 70% of the full price. You can then divide 15.75 by 70 [= 0.225] to get 1% of the full price. Multiply 0.225 by 100 to get the full price. 0.225 x 100 = 22.5
We can check that this answer is correct by multiplying 22.50 by 0.7. If you get 15.75 you know the answer is correct as 15.75 is 70% of the full price.

what is the number if 50% of 25% of the number is 96
Let n = the number we need to find.
0.50(0.25)n = 96
0.125n = 96
Can you finish?
The number if 50% of 25% of the number is 96 is 768
Let the unknown number be x
50% of 25% of the number is expressed as 0.5(0.25)x
0.5(0.25)x = 0.125x
Equating the result to 96 will give;
0.125x = 96
Divide both sides by 0.125
0.125x/0.125 = 96/0.125
x = 96/0.125
x = 768
Hence the number if 50% of 25% of the number is 96 is 768

A banker earns a $75,000 annual salary, a 2,35% commission on any approved loans for the bank’s business customers, and a fee of $3.75 for each application processed. If the banker has a total of 2.8 million in approved business loans and processes 2,750 applications this year, what are the banker’s earnings rounded to the nearest dollar ??
Answer:
Amount earned = $151,113
Step-by-step explanation:
Here, we are interested in calculating the banker’s earnings rounded to the nearest dollar;
We proceed as follows; we have the following;
1. Annual salary of $75,000
2. 2.35% on approved loans.
Approved loans = 2.8 million
Commission = 2.35/100 * 2.8 million = $65,800
3. $3.75 for each processed loan application
Total = 2750
Amount = 3.75 * 2750 = $10,312.50
Total amount earned is thus;
$75,000 + $65,800 + $10,312.50 = 151,112.5 = 151,113 to the nearest dollar
Find the equation of the line that is perpendicular to Y= -2/3x and contains the point (4,-8)
Answer:
Y=-3/5x
Step-by-step explanation:
Answer:
y = 3/2x -14
Step-by-step explanation:
y = -2/3 x
has a slope of -2/3
We want a line perpendicular
Take the negative reciprocal to find the slope
- (1 / -2/3)
3/2
The slope of a line perpendicular is 3/2
Using the slope intercept form of a line
y = mx+b where m is the slope and b is the y intercept
y = 3/2x +b
Substitute a point into the equation
-8 = 3/2(4) +b
-8= 6+b
Subtract 6 from each side
-8-6 = b
y = 3/2x -14

Which expressions are equivalent to the given complex number? 45 + 2i A. (2 + 8i) + 2(9 + 6i)(1 - i) B. (9 + 4i) + 2(4 + 7i)(1 - 2i) C. (13 + 4i) + 2(7 + 2i)(2 - i) D. (2 + 8i) + (30 - 6i) E. (9 + 4i) + (36 - 2i) F. (13 + 4i) + (32 - 6i)
The expressions which are equivalent to the complex number 45 + 2i is E. (9 + 4i) + (36 - 2i)
D. (2 + 8i) + (30 - 6i)
To determine which expressions are equivalent to the complex number 45 + 2i, we can simplify each expression and check if it matches the given number.
Let's evaluate each option:
A. (2 + 8i) + 2(9 + 6i)(1 - i) = 2 + 8i + 2(9 + 6i - 9i - 6i^2) = 2 + 8i + 2(9 + 6i - 9i + 6) = 2 + 8i + 2(15 - 3i) = 2 + 8i + 30 - 6i = 32 + 2i
B. (9 + 4i) + 2(4 + 7i)(1 - 2i) = 9 + 4i + 2(4 + 7i - 8i - 14i^2) = 9 + 4i + 2(4 + 7i - 8i + 14) = 9 + 4i + 2(23 - i) = 9 + 4i + 46 - 2i = 55 + 2i
C. (13 + 4i) + 2(7 + 2i)(2 - i) = 13 + 4i + 2(7 + 2i - 14i - 4i^2) = 13 + 4i + 2(7 + 2i - 14i + 4) = 13 + 4i + 2(24 - 12i) = 13 + 4i + 48 - 24i = 61 - 20i
D. (2 + 8i) + (30 - 6i) = 2 + 8i + 30 - 6i = 32 + 2i
E. (9 + 4i) + (36 - 2i) = 9 + 4i + 36 - 2i = 45 + 2i
F. (13 + 4i) + (32 - 6i) = 13 + 4i + 32 - 6i = 45 - 2i
From the evaluations above, we can see that options E and D are equivalent to the given complex number 45 + 2i.
The correct options are:
E. (9 + 4i) + (36 - 2i)
D. (2 + 8i) + (30 - 6i)

The expressions that are equivalent to the given complex number 45 + 2i are: (9 + 4i) + (36 - 2i) and (2 + 8i) + (30 - 6i).
Thus, option (D) and (E) are correct.
Given complex number 45 + 2i.
A. (2 + 8i) + 2(9 + 6i)(1 - i)
Simplifying: (2 + 8i) + 2(9 + 6i - 9i - 6)
= (2 + 8i) + 2(3 + 3i)
= 2 + 8i + 6 + 6i
= 8 + 14i
B. (9 + 4i) + 2(4 + 7i)(1 - 2i)
Simplifying: (9 + 4i) + 2(4 + 7i - 8i - 14)
= (9 + 4i) + 2(-10 - i)
= 9 + 4i - 20 - 2i
= -11 + 2i
C. (13 + 4i) + 2(7 + 2i)(2 - i)
Simplifying: (13 + 4i) + 2(14 + 4i - 7i - 2)
= (13 + 4i) + 2(12 - 3i)
= 13 + 4i + 24 - 6i
= 37 - 2i
D. (2 + 8i) + (30 - 6i)
Simplifying: 2 + 8i + 30 - 6i
= 32 + 2i
E. (9 + 4i) + (36 - 2i)
Simplifying: 9 + 4i + 36 - 2i
= 45 + 2i
F. (13 + 4i) + (32 - 6i)
Simplifying: 13 + 4i + 32 - 6i
