if x + y = 12 and x * y = -360 what are the values of x and y
Step-by-step explanation:
x + y = 12
x × y = -360
we need to transform one equation into an identity of one variable being expressed by the other variable.
e.g. the first equation gives us
x = -y + 12
and then we use that in the second equation :
(-y + 12) × y = -360
-y² + 12y = -360
y² - 12y - 360 = 0
the general solution for such a quadratic equation is
x = (-b ± sqrt(b² - 4ac))/(2a)
in our case
x = y
a = 1
b = -12
c = -360
y = (12 ± sqrt(144 - 4×1×-360))/2 =
= (12 ± sqrt(144 + 1440))/2 = (12 ± sqrt(1584))/2 =
= 6 ± sqrt(1584/4) = 6 ± sqrt(396) = 6 ± sqrt(36×11) =
= 6 ± 6×sqrt(11)
y1 = 6 + 6×sqrt(11) = 25.89974874...
y2 = 6 - 6×sqrt(11) = -13.89974874...
x1 = -y1 + 12 = -13.89974874...
x2 = -y2 + 12 = 25.89974874...
so, we see, they are interchangeable.
the solution is either
x = 25.89974874...
and
y = -13.89974874...
or
x = -13.89974874...
and
y = 25.89974874...

determine slope and what it represents!
Answer:
15 is the slope, it means you make $15 an hour
Step-by-step explanation:
$15 is found as the slope (see attachment), and because it's rise over run (15/1) then that is making $15 for every one hour worked.
Tori received $28.50 for 2 hours of work. How
much did she earn if she worked 15 hours?
Answer:
Hey! I hope this helps. I used ratio, I divided $28.50 by 2 to find out how much she worked for in an hour then I multiplied by 15.
A bicycle has a listed price of $556.98 before tax. If the sales tax rate is 8.75% find the total cost of the bicycle with sales tax included.
Round your answer to the nearest cent, as necessary.
Answer:
Total Price with Tax: $ 605.72
Step-by-step explanation:
We can write an equation for the total cost of the bicycle as:
C=p+(t×p)
Where:
C is the total cost we are trying to calculate.
p is the list price - $556.98
t is the tax rate - 8.75%. "%" means "out of 100" or "per 100", Therefore 8.75% can be written as 8.75 [tex]\frac{x}{100}[/tex].
Substituting and solving for C gives:
C = $556.98([tex]\frac{8\\.75}{100}[/tex]×$556.98)
C = $556.98+$48.74
C = $605.72

how many lines of symmetry does this rectangle have?
Answer:
sorry I don't know
Step-by-step explanation:
you have no image I can't tell
Answer: 2
Step-by-step explanation:
Rectangles have 2 lines of symmetry. One of them is vertically down the middle, and the other one is horizontally down the middle lengthwise. However, you can not draw the 2 symmetry lines diagonally in a rectangle from each corner to the opposite corner. An image is attached for a reference/example of this.

Nisha is looking out the window of her apartment building at a sculpture in a park across the street. The top of Nisha's window is 80 feet from the ground. The angle of depression from the top of Nisha's window to the bottom of the sculpture is 20°. How far away from the building is the sculpture? Round your answer to the nearest hundredth. 29. 11 feet 75. 18 feet 128. 67 feet 219. 80 feet.
Answer:
(d) 219.80 ft
Step-by-step explanation:
The side opposite the angle is given, and we want to find the side adjacent. The relevant trig relation is ...
Tan = Opposite/Adjacent
tan(20°) = (80 ft)/(distance to sculpture)
This rearranges to ...
distance to sculpture = (80 ft)/tan(20°) ≈ 219.80 ft
Given Trapezoid JOKE with m
Answer:
Step-by-step explanation:
In trapezoid JOKE, JO // EK
m∠J + m∠E = 180 {so-interior angles are supplementary }
m∠J +80 = 180
m∠J = 180 - 80
m∠J = 100
m∠O + m∠K = 180 {Co-interior angles are supplementary}
m∠O + 50 = 180
m∠O = 180 -50
m∠O = 130

Evaluate x/y if x= 4/5 and y= −0.1 . Write your answer in simplest form.
Answer:
-8
Step-by-step explanation:
given x as 4/5 and y = - 0.1...
converting x to decimal it becomes 0.8
we then input values for x and y in the equation x/y
x/y = 0.8 / -0.1 = -8
The value of the fraction x/y is -8.
Given that, x= 4/5 and y= −0.1.
What is the fraction?In Mathematics, fractions are represented as a numerical value, which defines a part of a whole. A fraction can be a portion or section of any quantity out of a whole, where the whole can be any number, a specific value, or a thing.
To find the value of fraction x/y:
Here, x=4/5 = 0.8
Now, x/y = 0.8/(-0.1)
= -8
Hence, the value of the fraction x/y is -8.

X+3>70
A. 61
B. 66
C. 50
D. 67
E. 70
Answer: Choice D and Choice E
Explanation:
Subtract 3 from both sides
x+3 > 70
x+3-3 > 70-3
x+0 > 67
x > 67
Any number larger than 67 will make the original inequality to be true.
Unfortunately, only E) 70 fits the description.
D) 67 won't work since 67 > 67 is false.
However, I have a feeling that the original inequality might be [tex]x+3 \ge 70[/tex]. If so, then 67 would work because [tex]67\ge 67[/tex] is true.
So I'll assume that this is the inequality you meant to type out.

At 8 a.m., the temperature in Phoenix, Arizona, is 74°F. The Temperature increases 25% by 11 a.m. and another 20% by 2 p.m. What is the temperature at 2 p.m.? Round your answer to the nearest tenth of a degree Fahrenheit.
(I ALREADY KNOW THE ANSWER. BUT I NEED THE WORK FOR THE ANSWER TO SHOW MY TEACHER) (the answer is 111.0 °F)
The final temperature is original temp + original temp * temp increase

Which graph represents the solution of |–2 + (x – 3)| < 7?
Answer:
D
Step-by-step explanation:
the "<" (or "smaller") symbol tells us that the solution must have empty dots at the interval ends, as these values are not included in the solution.
otherwise, we would have a "<=" ("smaller or equal") symbol.
let's start for the first limit to calculate without the absolute value :
-2 + (x - 3) < 7
-5 + x < 7
x < 12
the other end we get by multiplying only the left side (still without the absolute value) by -1 and do it again :
-1×(-2 + (x - 3)) < 7
2 - (x - 3) < 7
2 - x + 3 < 7
-x + 5 < 7
-x < 2
x > -2 (remember, when we multiply the whole inequality, left and right side, by a negative value, we need to flip the inequality symbol).
Wym has a packet of 50 biscuits she gives half of them to her friend and then eats 8 how many are left
Answer:
17 biscuits
Step-by-step explanation:
Since she starts with 50 and gives away half which is 25, that will leave her with 25 biscuits herself. If she then eats 8 of them, that will leave her with 17 since 25-8=17.
