What is (-1,2) rotated 90 degrees clockwise
Answer: 2, 1
Step-by-step explanation:
Whenever you rotate a point on a graph 90 degrees you go from (x,y) to (y,-x)
so -1, 2 goes to 2, 1
54x + 15 = -3 (3y + 1)
I need help finding the equation for y
Answer: y = -6x - 2
Step-by-step explanation:
54x + 15 = -3(3y + 1) To solve for y distribute on the right side to get,
54x + 15 = -9y -3 Add 3 to both sides
+3 +3
54x + 18 = -9y Divide each term by -9 on each side.
y = -6x - 2
Answer______
54x + 15 = -3 (3y + 1)
54x + 15 = -9y -3
+3 +3
54x + 18 = -9y
y = -6x - 2

Darlene purchases 20,000 worth of stock on her brokers advice and pays her broker a 1.5% broker fee darlene purchases 20,000 worth of stock on your brokers advice and pays her broker a 1.5% broker freeshe sells her stock when it increases to $28,600.02 years later and uses a discount broker who charges $21 per trade compute Darlenes net proceeds after the broker fees are taken out
Answer:
Darlene's net proceeds after the broker fees are taken out is $8,279.
Step-by-step explanation:
From the question, the following can be obtained:
Basic cost of purchase of the stock = $20,000
Broker fee related to purchase = Basic cost of purchase of the stock * 1.5% = $20,000 * 1.5% = 300
Total cost of purchase of the stock = Basic cost of purchase of the stock + Broker fee related to purchase = $20,000 + 300 = $20,300
Selling price = $28,600
Broker fees related sales = 21
The net proceed can therefore be calculated as follows:
Net proceeds = Selling price - Broker fees related sales - Total cost of purchase of the stock = $28,600 - $21 - $20,300 = $8,279
Therefore, Darlene's net proceeds after the broker fees are taken out is $8,279.

Answer:
$1,539.70
Step-by-step explanation:
Given the data :
National average Teachers' salary (NATS)
YEAR:_1960 _ 1970 _ 1980 _ 1990 _ 2000 2010
NATS:4995_8626_15970_31367_41807_55202
AVEAGE SALARY INCREASE PER YEAR BETWEEN 1980 and 1990
Salary in 1980 = $15970
Salary in 1990 = $31367
Average salary increase per year:
Difference in salary / difference in years
$(31367 - 15970) / (1990 - 1980)
= $15397 / 10
= $1539.7

What is an equation of the line that passes through the points (-3, -1)(and (-4, -4)? Put your answer in fully reduced form.
Answer:
y=3x+8
Step-by-step explanation:
m=3
y-(-1)=3(x-(-3))
y+1=3x+9
y=3x+8
The equation of the line passes through the point (-3, -1)(and (-4, -4) is y=3x+8.
What is an equation of the line?An equation of the line is defined as a linear equation having a degree of one. The equation of the line contains two variables x and y. And the third parameter is the slope of the line which represents the elevation of the line.
The general form of the equation of the line:-
y = mx + c
m = slope
c = y-intercept
Slope = ( y₂ - y₁ ) / ( x₂ - x₁ )
Given that line passes through the points (-3, -1)(and (-4, -4)
The slope will be calculated as,
Slope = ( y₂ - y₁ ) / ( x₂ - x₁ )
Slope = ( -4 + 1 ) / ( -4 + 3 )
Slope = 3
The y-intercept is calculated as,
y = 3x + c
-1 = 3 x -3 + c
c = 8
The equation of the line will be,
y=3x+8

Answer:
19, 18, 15.5
Step-by-step explanation:
b(-2) =

18 - (-1)
b(x) = 19
b(0) =
18 - 0.5(0)
18 - 0 =
b(x) = 18
b(5) =
18 - 0.5(5)
18 - 2.5

Please help I’m really stuck
can this problem be solved?
Answer:
The discriminant is -23
The equation has 0 real solution
Step-by-step explanation:
The discriminant of the quadratic equation ax² + b x + c = 0 is Δ = b² - 4ac
If Δ > 0, then the equation has two different real solutionsIf Δ = 0, then the equation has one real solutionIf Δ < 0, then the equation has no real solutionsLet us use the rule above to solve the question
∵ x² - x + 6 = 0
∴ a = 1, b = -1 and c = 6
∵ Δ = b² - 4ac
∴ Δ = (-1)² - 4(1)(6)
∴ Δ = 1 - 24
∴ Δ = -23
∴ The discriminant is -23
∵ -23 < 0
∴ Δ < 0
∴ The equation has no real solutions
∴ The equation has 0 real solution
