Answer:
-1 , 10 and 10 , -1
Step-by-step explanation:
hello :
if x , y this numbers you have the system : x+y =9.....(*)
xy = -10.....(**)
use (*) : y = 9 - x
put this value of y in (**) : x(9-x) = -10
9x - x² = - 10
x²-9x - 10 = 0
(x+1)(x-10)=0 means : x+1 = 0 or x -10 = 0
x = - 1 or x=10
if : x= -1 y = 9-(-1)=10
if : x= 10 y = 9-(10)=1
Please help!!!! PLEASE!
Consider the following pair of equations:
y = x + 4
y = −2x − 2
Explain how you will solve the pair of equations by substitution. Show all the steps and write the solution in (x, y) form. (5 points)
Answer:
(-2,2)
Step-by-step explanation:
Substitute answer for y in first equation (y=x + 4) into y of second equation
x+4=-2x-2
3x=-6
x=-2
put value of x (-2) into either equation to solve for y
y=x+4
y=-2+4
y=2
or y=-2x-2
y=-2(-2)-2
y=4-2
y=2
If one adult works 4 weeks per month at
40 hours per week, what is the minimum hourly
wage, to the nearest cent, that person must
earn in order to meet the family's budget
needs?
Answer:
15.21
Step-by-step explanation:
All of the bills total to $2432.50. The person works 160 hours in a month. $2432.50 ÷ 160 = $15.20, BUT:
$15.20 × 160 = $2432, which is 50 cents short of what they need, so one extra cent in their wage will give them the amount they need.
$15.21 × 160 = $2433.60

Calcula el RIQ de las temperaturas en las Ciudades de Kansas, Misouri las temperaturas: 23,25,28,28,32,33,35 y en Paradise, Michigan. Las temperaturas: 16,24,26,26,26,27,28 *
Respuesta:
Kansas, Misuri = 8
Paradise, Michigan = 3
Explicación paso a paso:
El rango intercuartílico (IQR) = Q3 - Q1
Q3 = 3/4 (n + 1) th término
n = número de muestras
Q1 = 1/4 (n + 1) th término
Kansas Misuri:
23,25,28,28,32,33,35
Datos pedidos: 23, 25, 28, 28, 32, 33, 35
n = 7
Q1 = 1/4 * 8 = 2do trimestre = 25
Q3 = 3/4 * 8 = 6. ° tem = 33
Q1 = 33 - 25 = 8
Paradise, Michigan:
16,24,26,26,26,27,28
Datos pedidos: 16,24,26,26,26,27,28
Q1 = 1/4 * 8 = 2do = 24
Q3 =. 3/4 * 8 = 6to = 27
Q3 - Q1 = 27 - 24 = 3
if cos a=0•8, what Is the value of tan a
Answer: 0.75
Step-by-step explanation:
Cos A = 0.8 = 4/5
Note that:
sin = opposite / hypotenuse
cos = adjacent / hypotenuse
tan = opposite / adjacent
Since cos = adjacent / hypotenuse
Therefore, we need to find the opposite which will be:
Hypothenuse² = Opposite² + Adjacent²
5² = Opposite² + 4²
Opposite² = 5² - 4²
Opposite² = 25 - 16
Opposite² = 9
Opposite = ✓9
Opposite = 3
Since tangent = opposite / adjacent
Tan a = 3/4 = 0.75

Answer:
The answer is 5 1/16
Step-by-step explanation:
3/2 x 3/2 x 3/2 x 3/2
3/2 x 3/2 = 9/4
9/4 x 3/2 = 27/8
27/6 x 3/2 =81/16
Turn 81/16 into a mixed fraction and it’s 5 1/16
Therefore, the answer is 5 1/16
Select all expressions that are equivalent to 4(y + 2).
A 4y + 2
B4y + 8
Cy+y + y + y +2
D 5(y +2) – (y + 2)
Ey + y + y + y + 2+2+2+2
F.5(y + 2) - (y – 2)
Answer:
BDEStep-by-step explanation:
× A = 4y + 2 = 2(4y/2 + 2/2) = 2(2y + 1) ≠ 4(y + 2)
✓ B = 4y + 8 = 4(4y/4 + 8/4) = 4(y + 2) = 4(y + 2)
× C = y + y + y + y + 2 =
y (1 + 1 + 1 + 1) + 2 = 4y + 2 = A ≠ 4(y + 2)
✓ D = 5(y + 2) – (y + 2) = 5(y + 2) – 1(y + 2) =
(5 – 1)(y + 2) = 4(y + 2)
✓ E = y + y + y + y + 2 + 2 + 2 + 2 =
y (1 + 1 + 1 + 1) + (2 + 2 + 2 + 2) =
4y + 8 = B = 4(y + 2)
× F = 5(y + 2) – (y – 2) =
(5y + 10) + (-y + 2) =
(5y – y) + (10 + 2) =
4y + 12 = 4(y + 3) ≠ 4(y + 2)

Enter the equation of the circle with the given center and radius.
Center: (0, 5); radius: 5
The equation of the circle is
Answer:
[tex](x-0)^{2} + (y-5)^{2} = 25[/tex]
Step-by-step explanation:
The "template" equation of a circle is:
[tex](x-h)^{2} + (y-k)^{2} = r^{2}[/tex]
All you're doing after that, is filling in the blanks:
h = 0
k = 5
r = 5
Answer:
Correct answer:
(x−0)² + ( y−5)²=5²
Explanation:
The equation of a circle is (x−h)²+(y−k)²=r²
The center is (0,5) or, written another way (h,k). Substituting 0 for h and 5 for k, our formula becomes (x−0)²+(y−5)²=5²
Finally, the formula of the circle is (x−0)²+(y−5)²=25
5e^5x =20
What is the approximate solution to this equation
Answers provided
Answer:
i think its B
Step-by-step explanation:
The appropriate solution to the equation; 5e^5x =20 is Choice D; x = 0.28.
From the question;
The equation given is; 5e^5x =20To solve the given equation; we must evaluate x as follows;
First, we divide both sides of the equation by 5; so that we have;
e^5x = 20/5 = 4.Next, we take the natural log of both sides so that we have;
5x = ln(4)5x = 1.386x = 0.28

A customer left an 18% gratuity of $27. What was the amount of the bill? $27.18 $43.00 $150.00 $486.00
Answer:
The amount of the bill was $150.
Step-by-step explanation:
With the information provided, you can use a rule of three to find the amount of the bill which would represent 100% given that $27 represent 18%:
18% → 27
100% → x
x=(100*27)/18
x=150
According to this, the answer is that the amount of the bill was $150.

Given:
Grocery store located at point (5,-4).
Park is located at point (-5,4).
Paula's house is halfway between the Grocery store and park.
School is halfway between the Paula's house and park.
To find:
Ordered pair for the school.
Solution:
Formula used:
[tex]\text{Midpoint}=\left(\dfrac{x_1+x_2}{2},\dfrac{y_1+y_2}{2}\right)[/tex]
Paula's house is halfway between the Grocery store and park. It means the location of Paula's house is the midpoint of (5,-4) and (-5,4).
[tex]\text{Paula's house}=\left(\dfrac{5+(-5)}{2},\dfrac{(-4)+4}{2}\right)[/tex]
[tex]\text{Paula's house}=\left(\dfrac{0}{2},\dfrac{0}{2}\right)[/tex]
[tex]\text{Paula's house}=\left(0,0\right)[/tex]
So, the Paula's house is located at (0,0).
School is halfway between the Paula's house and park. It means the location of the school is the midpoint of (0,0) and (-5,4).
[tex]\text{School}=\left(\dfrac{0+(-5)}{2},\dfrac{0+4}{2}\right)[/tex]
[tex]\text{School}=\left(\dfrac{-5}{2},\dfrac{4}{2}\right)[/tex]
[tex]\text{School}=\left(-2.5,2\right)[/tex]
