Solve the system by using the elimination method.
Answers
Answer:
(8, 4 )
Step-by-step explanation:
Given the 2 equations
5x - 5y = 20 → (1)
- 3x + 5y = - 4 → (2)
Add the 2 equations term by term to eliminate the y- term
2x + 0 = 16
2x = 16 ( divide both sides by 2 )
x = 8
Substitute x = 8 into either of the 2 equations and solve for y
Substituting into (2)
- 3(8) + 5y = - 4
- 24 + 5y = - 4 ( add 24 to both sides )
5y = 20 ( divide both sides by 5 )
y = 4
solution is (8, 4 )

Answers
Answer:
FHG is 45 degrees
Step-by-step explanation:
For a square, each of the angles at the corners measure 90 degrees
Also, the two diagonals are equal and they bisect one another
Also, the diagonals bisect each of the angles at the corners making each angle lying in each triangle to be 45 degrees, thereby creating 4 isosceles right triangles
For FHG, looking at the triangle FHG, FG and GH are equal lengths as we have an isosceles right triangle
An isosceles right triangle is only possible when the two internal angles asides the right triangle are 45 degrees each
What this mean is that FHG measure is 45 degrees

Answer:

Step-by-step explanation:
Let f(t) represent the temperature of a turkey baking in an oven as a function of time t in the oven (in minutes). This means time is the independent variable and temperature of the turkey is the dependent variable. The turkey was in the oven for 360 minutes and then removed. Note that when something is baked in an oven, the temperature of the oven stays constant.
Explain the meaning of each statement in the context of the situation using everyday language. Remember that the input of the function t is the time in the oven and the output f(t) is the temperature of the turkey at that time.
1. f(0) = 50. (8 points)
2. f(120) > f(60). (8 points)
3. f(360) = f(345). (7 points)
4. f(390) < f(360). (7 points)
Answers
Answer:
Step-by-step explanation:
1. f(0) = 50. (8 points) The beginning temperature of the turkey was 50 degrees. The '0' represents "beginning."
2. f(120) > f(60). (8 points) The temperature of the turkey after 120 min (2 hours) is greater than that after 60 minutes (1 hour).
3. f(360) = f(345). (7 points) The temperature of the turkey is the same after 360 minutes as it is after 345 minutes.
4. f(390) < f(360). (7 points)
The temperature of the turkey drops after 360 minutes (6 hours), because the turkey is taken out of the oven and/or the oven is turned off.

Use the formula pi r^2. You are finding the radius. Plug the numbers in.
Answer:
Should be the second one.
Step-by-step explanation:First you have to think that the entire circle is blue. So the area of the blue circle is: 3.14*11^2 = 379.94.
Then you have to look at the smaller circle. There the radius is: 3. So the area would be: 3.14*3^2 = 28.26
They are asking you to find the shaded area. So you subtract the bigger circles area with the smaller circle.
379.94 - 28.26 = 351.68 to the exact.

Una botella pesa 1090kg cuando esta llena y 250g cuando esta vacía. ¿Cuanta masa de aceite contiene la botella?
Answers
Respuesta:
1089,75 kg
Explicación paso a paso:
Dado que :
Masa de embotellado lleno = 1090 kg
Masa de la botella vacía = 250 g
Masa de aceite que contiene la botella:
Expresando la masa de la botella cuando se llena en gramos:
1000 g = 1 kg
1090 kg = (1090 * 1000) = 1090000 g
La masa de aceite que contiene la botella es así:
Masa de la botella cuando está llena - masa de la botella cuando está vacía
1090000 g - 250 g = 1089750 g
Por tanto, la masa de aceite es 1089750 g
O 1089750/1000 = 1089,75 kg

On a given planet, the weight of an object varies directly with the mass of the object. Suppose that an object whose mass is 9 kg weighs 63 N . Calculate the mass of another object that weighs 14 N.
Answers
Answer:
The mass is 2 kg.
Step-by-step explanation:
W = kM where k is a constant so
63 = k*9
k = 7
So: W = 7M
when W = 14:
14 = 7M
M = 2.

y-int = (0, -1.26)
x-int = (2, 0)
Explanation:
Key: 3/ = cube root
| = end of cube root
To find the y-int, you make x equal to zero...
3/ x - 2
3/ 0 - 2
3/ -2
and to find the x-int, you make the entire function equal to zero...
3/ x - 2 | = 0
x - 2 = 0 (cube sides to get rid of cube root)
x = 2
To find any other points, just plug in an x to the original function, and the answer you get will be the y.
