Answers
Answer:
The solution of the system is (9,-8)
Step-by-step explanation:
2x+2y=2
3x-2y= 43
5x = 45
x = 9
2(9) + 2y = 2
18 + 2y = 2
2y = -16
y = -8

please help
Answers
Answer:
Here we can see that two lines are intersecting so that the angles formed will be vertically opposite angles,
Thus, the value of both angles will be equal
i.e., x+3 = 84
⇒ x = 84 - 3
⇒ x = 81
Thus the value of x is 81

Hallie made 12 quarts of homemade yogurt. She put the yogurt in 34-cup containers. How many containers did Hallie fill?
Answers
Answer:
1 container and 14 cups
Step-by-step explanation:
We know that 1 quart = 4 cups
therefore, 12 quart = 48 cups
each container has 34 cups
so one container would be full and remaining 48-34 =14 cups can be filled in another container.
Can two obtuse angles be supplementary? Explain why or why not
Answers
Answer:
no
Step-by-step explanation:
No, two obtuse angles cannot form a supplementary angle. By the definition of obtuse angles, the angles that measure greater than 90° are obtuse. If you add two obtuse angles, the sum will be greater than 180°. It will not satisfy the property of the supplementary angles when we add obtuse angles.
Answer: the answer is No
Step-by-step explanation: the answer is no because, two obtuse angles cannot form a supplementary angle. By the definition of obtuse angles, the angles that measure greater than 90° are obtuse. If you add two obtuse angles, the sum will be greater than 180°. It will not satisfy the property of the supplementary angles when we add obtuse angles.

Irrational because it is a decimal that doesn´t repeat or terminate
Step-by-step explanation:
A delivery driver is traveling a total of 250 miles from a warehouse to a store at an average speed of 45 miles per hour. The function f(x)=250-45xf(x)=250−45x represents the distance remaining, in miles, after traveling for xx hours.
Answers
Answer:
115miles
Step-by-step explanation:
Given the function of the distance remaining represented by the function
f(x) =250-45x where;
x is the time taken in hours
Since we are not told what to loom for, we can calculate the distance remaining after 3hrs.
Substitute x =3 into the equation
f(3) = 250-45(3)
f(3) = 250-135
f(3) = 115
Hence the distance remaining after 3 hrs is 115miles

The sum of 3 consecutive integers is 30.
What is the third number in this sequence?
Answers
Answer:
11
Step-by-step explanation:
the 3 numbers are 9, 10, 11
Answer:
Third number = 11
Step-by-step explanation:
Let 3 consecutive numbers be x ,x +1 , x +2
x +x+1 + x+ 2 = 30
x +x +x + 1 + 2 = 30 {Combine like terms}
3x + 3 = 30 {Subtract 3 from both sides}
3x = 30 - 3
3x = 27 {Divide both sides by 3}
x = 27/3
x = 9
Third number =x + 2 = 9 + 2 = 11

the time at which the rocket will reach its max, to the nearest 100th of a second.
y=16x^2+ +225x+79
Answers
Answer:
7.03 seconds
Step-by-step explanation:
First, you need to differentiate the equation (The derivative of y represents the rocket's velocity):
y' = 32x + 225
Then, set y' to 0 and solve for x
0 = 32x + 225
x = 7.03s

Find the area of the region shaded in green. Use 3.14 to approximate pi.
Answers
Answer:
254 cm² (to 3 s.f.)
Step-by-step explanation:
Area of shaded region
= area of large circle -area of smaller circle
[tex]\boxed{area \: of \: circle = \pi {r}^{2} }[/tex]
Radius of large circle= 15cm
Radius of smaller circle= 12cm
Area of shaded region
= π(15²) -π(12²)
= 225π -144π
= 81π
= 81(3.14)
= 254.34
= 254 cm² (3 s.f.)

Answers
Answer:
Option C
Step-by-step explanation:
Height of the rocket is modeled by,
h(t) = -16t² + 125t + 24
Height of the rocket in t = 0.1 seconds
h(0.1) = -16(0.1)² + 125(0.1) + 24
= -0.16 + 12.5 + 24
= 36.34 feet
At t = 5 seconds,
h(0.5) = -16(5)² + 125(5) + 24
= -400 + 625 + 24
= 249 feet
At t = 5.6 seconds,
h(5.6) = -16(5.6)²+ 125(5.6) + 24
= -501.76 + 700 + 24
= 222.24 feet
At t = 7.8 seconds,
h(7.8) = -16(7.8)² + 125(7.8) + 24
= -973.44 + 975 + 24
= 25.56 feet
Therefore, change in height is maximum at t = 5.6 seconds
Option C will be the answer.

The value, in dollars, of an antique has increased exponentially over x years as shown in the graph. image What are the domain and range of the function? A. Domain: x ≥ 0 Range: y ≥ 0 B. Domain: x ≥ 0 Range: y ≥ 1,000 C. Domain: all real numbers Range: y ≥ 1,000 D. Domain: all real numbers Range: y ≥ 0
Answers
Answer:
C. Domain: all real numbers Range: y ≥ 1,000
Step-by-step explanation:
0 to 10 years = 50
30 to 40 years = 150
Domain: all real numbers and Range: y ≥ 1,000, which is the correct answer would be an option (C).
What are the domain and range of the function?The domain of the function includes all possible x values of a function, and the range includes all possible y values of the function.
The graph is given in the question.
The value, in dollars, of an antique, has increased exponentially over x years as shown in the given graph.
We have to determine the domain and range of the function.
As per the given graph,
we can see that the values of the x-axis are all real numbers in the graph which means its domain is all real numbers and the value of the y-axis begins at 1000 and continuously increases, therefore this means the range of the function is y ≥ 1,000.
Thus, Domain: all real numbers and Range: y ≥ 1,000.
Hence, the correct answer would be an option (C).
