A quadratic function models the graph of a parabola. The quadratic functions, y = x2 and y = x2 + 3, are modeled in the graphs of the parabolas shown below. Determine which situations best represent the scenario shown in the graph of the quadratic functions, y = x2 and y = x2 + 3. Select all that apply. From x = -2 to x = 0, the average rate of change for both functions is negative For the quadratic function, y = x2, the coordinate (2, 3) is a solution to the equation of the function. The quadratic function, y = x2 + 3, has an x-intercept at the origin The quadratic function, y = x2, has an x-intercept at the origin From x = -2 to x = 0, the average rate of change for both functions is positive For the quadratic function, y = x2 + 3, the coordinate (2, 7) is a solution to the equation of the function.
Answers
Answer:
Step-by-step explanation:
From x = -2 to x = 0, the average rate of change for both functions is negative
The quadratic function, y = x2, has an x-intercept at the origin
For the quadratic function, y = x2 + 3, the coordinate (2, 7) is a solution to the equation of the function.
those 3 are good
The quadratic function, y = x², has an x-intercept at the origin is, TRUE
And, The quadratic function, y = x² + 3, has an x-intercept at the origin is, FALSE
From x = -2 to x = 0, the average rate of change for both functions is positive is, FALSE
What is mean by Function?A relation between a set of inputs having one output each is called a function. and an expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable (the dependent variable).
Now, We have;
When viewing a graph, you start from the left and go to right and from left to right from -2 to 0 the graph is declining.
Hence, From x = -2 to x = 0, the average rate of change for both functions is negative is true.
And, Both are declining if you read the graph from left to right.
For the quadratic function, y = x², the coordinate (2, 3) is a solution to the equation of the function is false.
y = x²
If we insert 2 into y = x² we get y = 4 but our point (2, 3) has y = 3
For the quadratic function, y = x² + 3, the coordinate (2, 7) is a solution to the equation of the function is true.
If we insert 2 for x, we see that;
⇒ y = x² + 3
⇒ y = 2² + 3
⇒ y = 7
And, our y value in the point (2, 7) is 7.

Answer:
x = 10
Step-by-step explanation:
Diagonals of a rhombus bisect each other at a 90° angle, but most importantly (for this problem), they bisect the opposite angles of the rhombus equally.
This means that the two angles, given by the expressions (6x + 12) and (8x - 8), are equal to each other.
Set them equal to each other in an equation and solve for x.
6x + 12 = 8x - 8Subtract 6x from both sides.
12 = 2x - 8Add 8 to both sides.
20 = 2xDivide both sides by 2.
x = 10The value of 10 for x will make the given parallelogram a rhombus.

Miley can walk 5 1/2 miles and 1 2/3 hours how far can she walk in four hours?
Answers
Answer:
Miley can walk a distance of [tex]13\frac{1}{5}[/tex] miles in four hours.
Step-by-step explanation:
Given that:
Distance walked by Miley in [tex]1\frac{2}{3}[/tex] hours = [tex]5\frac{1}{2}[/tex] miles
We will find unit rate in term of hours.
[tex]\frac{5}{3}\ hours = \frac{11}{2}\ miles[/tex]
Multiplying both sides by 3/5
[tex]\frac{3}{5}*\frac{5}{3}\ hour = \frac{11}{2}*\frac{3}{5}\\\\Unit\ rate = \frac{33}{10}\miles\ per\ hour[/tex]
Distance walked in four hours = [tex]4*\frac{33}{10}\ miles[/tex]
Distance walked in 4 hours = [tex]\frac{66}{5}=13\frac{1}{5}\ miles[/tex]
Hence,
Miley can walk a distance of [tex]13\frac{1}{5}[/tex] miles in four hours.

y° = 70°
z° = 140°

Therefore, y° = 70°
Measure of central angle is two times the measure of the inscribed angle.

Which direction will the box move in the diagram below?
A.It will move to the left.
B.It will move to the right.
C.It will not move.
D.It will move up.
Answers
Answer:
B.it will move to the right.
Explanation:
We have 5 newtons of force pushing to the right, and 3 newtons of force pushing to the left. We can place the positive direction on the right hand side and the negative direction on the left.
This means we can think of "3 newtons of force to the left" as the integer -3
That way we can then add 5 to -3 getting 5+(-3) = 2. The result is positive, meaning the net force is pushing to the right. Specifically, 2 newtons of force are pushing to the right.
It's like saying there are 5 people pushing to the right and 3 pushing to the left. From each side, 3 people will pair up and they'll cancel each other out. The 2 extra people pushing right will ultimately win out.
