The data is larger for intermediate values of x, so the parabola opens downward. That leaves only the 2nd and 4th choices, where the x² coefficient is negative.

To determine which of those is appropriate, it is only necessary to consider x=1. The 2nd choice will give a y-value near 100; the 4th choice will give a y-value near 250.

The fourth choice is appropriate:

... y = -9.16x² +73.04x +183.3

_____

Alternatively, you can consider that for the x-coordinate of the vertex to be positive (it's about +4), the coefficients of the x² and x terms must have opposite signs. Using this consideration, you don't even need to evaluate the expression to determine that the 4th choice is the correct one.

7(x-4)=14 what are the steps?

Vaselesa [24]

Answer:

x=6

Step-by-step explanation:

multiply 7 by x and 7 by -4. You get 7x-28=14, add 28 to 14, which is 42. So 7x=42, then divide 7 on both sides, and you get x=6.

Min: 2 Q1: 7.5 Med: 11 Q3:14 Max:17

Step-by-step explanation:

Min is the minimum value of the provided data. In this case it is easier to tell because the numbers are arranged in ascending order;

The minimum value is;

= 2

Quartile 1 is the value that divides into half, the first half of the provides values. The first half of the value is divided by the median (In this case 11). The value that is halfway the values before median value is the Q1

In this case, we end up with two values because the numbers of values are even;

6 & 9

We sum the two and divide by 2

(6 + 9) / 2 = 7.5

Median is the value that is in the middle of all the provided values arranged in ascending order. Because the values are even, we end up with two numbers;

11 & 11

Again we sum the two and divide by 2;

(11 + 11) / 2 = 11

Quartile 3 is the value that divides into half, the second half of the provided values. This means the value three-quaters way. Because the number of provides values is even, then we end up with two values;

14 & 14

We sum the two and divide by 2

(14 + 14) / 2 = 14

Max value is the largest number of all the values;

= 17

Which is the best approximate solution of the system of linear equations y= 1.5x - 1 and y = 1

yan [13]

Answer:

4/3

Step-by-step explanation:

We can immediately eliminate y by setting y = 1 equal to y = 1.5x - 1:

1 = 1.5x - 1, or 1.5x = 2, or x = 2/1.5 = 4/3

SAM ≅ ΔZYX , Options: M = 36 M = 60 M = 84 M = 102

Reil [10]

Answer:

M = 36

Step-by-step explanation:

Since SAM = ZYX

We can assume that all angles on SAM will equal the same as ZYX.

There are 180° total in a triangle, so you add 60 + 84, which equals 144, then you subtract 144 from 180 to find the remaining angle.

Therefore M = 36°

With unique examples of your own let’s discuss the number of solutions possible (0, 1, 2, 3, 4) to a system of equations that in

The number of solutions possible to a system of equations that include a conic section depends on the type of equations involved

<h3>How to determine the number of solutions?</h3>

A system of equation that has a conic section may or may not have solutions.

It would have a solution if the equations intersect, when plotted on a graph and it would not, if otherwise

A conic section can be any of:

Parabola
Ellipse
Hyperbola
Circle

Example 1: No solution

Consider the following system of equations

y = x² - 10 --- parabola equation
(x - 1)² + (y - 2)² = 5 --- circle

The above system of equations has no solution because they do not intersect when plotted on a graph (see graph 1)

Example 2: One solution

Consider the following system of equations

x = 2 --- linear equation
y = x² - 10 --- parabola

The above system of equations has one solution because they intersect at one point (see graph 2)

Example 3: One solution

Consider the following system of equations

y = 2x + 1 --- linear equation
y = x² - 10 --- circle

The above system of equations has two solutions because they intersect at two points (see graph 3)

The above examples imply that a system of equations that involves conic section can have as many solutions as possible.

The number of solutions depends on the type of equations involved

The attached graphs illustrate how a system of equations can have 0 to 4 solutions
