Answer:

Option (1)

Step-by-step explanation:

System of equations has been given as

2x + 6y = 14

By dividing this equation by 2

x + 3y = 7 --------(1)

Second equation is,

-2x + 2y = -10

-x + y = -5 -------(2)

By adding equation (1) and equation (2)

(x + 3y) + (-x + y) = 7 - 5

2x = 2

x = 1

By putting x = 1 in the equation (1)

1 + 3y = 7

3y = 6

y = 2

So, we get exactly one solution pair (1, 2) where these lines are intersecting.

Therefore, the best category that defines the system of equations is Consistent/Independent

Option (1) will be the answer.

Answer:

17, 23

Step-by-step explanation:

First, to find the radius, we need to find the distance between the center of the circle, (-7, -1), and the point that the circle passes through, (8, 7). Plugging these coordinates into the distance formula we do [tex]\sqrt{(-7-8)^2+(-1-7)^2}[/tex] which gives us 17. Therefore, the radius of the circle is 17 units.

Next to find the y-coordinate of the point (-15, ), we need to write out the equation of the circle and then plug in the point. The equation of the circle would be [tex](x+7)^{2} +(y-8)^{2}=289[/tex]. Now we can plug in -15 for x and solve for y. So now we have [tex](-15+7)^{2} +(y-8)^{2}=289[/tex].

Simplifying the equation we have [tex](8)^{2} +(y-8)^{2}=289[/tex]. Subract [tex]8^{2}[/tex] from 289 and now the equation is [tex](y-8)^{2}=225[/tex]. Square root both sides to get [tex]y-8=15[/tex]. We solve for y to get 23. Therefore, the point is (-15, 23).

We need to remember that a type of error II if the error associated when we NO reject the null hypothesis when actually the alternative hypothesis is true. And is also known as false negative. The best answer for this case would be:

D. The manufacturer will decide the mean battery life is 8.3 hours when in fact it is greater than 8.3 hours.

Since we are FAILING to reject the null hypothesis when the true mean is actually higher than the value specified

Step-by-step explanation:

For this case we want to determine if mean running time has increased as a result of the new change so then the system of hypothesis are given by:

Note: we assume that the value to check in order to be consistent with the options is 8.3

Ha: μ > 8.3 hours

  A.  A horizontal shift to the right 7.5 units

Step-by-step explanation:

Replacing x with x-7.5 shifts the graph 7.5 units to the right.

In general, g(x) = f(x-h)+k will shift h units right and k units up. In this problem there is no vertical shift.

Rise over run. Or I believe. Like If I chose (-1,2) and (0,-1)  the rise or in this case since the line is going down, if I move down 4 units. I am one unit to the left of (0,-1) so 4/1 so rise/run

The equation of the line is y+2x+1 = 0.

A line's equation is an algebraic way of expressing the collection of points that make up a line in a coordinate system.

The many points that collectively make up a line on the coordinate axis are represented as a group of variables (x, y) to create an algebraic equation, also known as an equation of a line.

In the given graph,

Line intersect x-axis at -1/2

And intersect y-axis at -1

The points are (-1/2,0) and (0,-1)

The slope of the line m = -1-0/(0-(-1/2)) = -2

The required equation of the line that passes through the point (-1/2,0) and slope is -2,

y-0 = -2(x-(-1/2))

⇒y=-2x-1

⇒y+2x+1 = 0

The equation of the line is y+2x+1 = 0.

Answer:[tex]8.75\ m^2[/tex]

Step-by-step explanation:

Given

Area of circle is [tex]A=45\ m^2[/tex]

Arc measure [tex]\theta =70^{\circ}[/tex]

and area of sector is given by

[tex]\Rightarrow \frac{\theta }{360^{\circ}}\times \text{Area of circle}[/tex]

[tex]\Rightarrow \frac{70}{360}\times 45[/tex]

[tex]\Rightarrow 0.194\times 45[/tex]

[tex]\Rightarrow 8.75\ m^2[/tex]

So, area of sector is [tex]8.75\ m^2[/tex]

Answer:

[tex](3x+1)^2[/tex]

Step-by-step explanation:

[tex]9x^2+6x+1=\\(3x+1)^2[/tex]

You can confirm this by working and expanding backwards:

[tex](3x+1)^2=\\(3x+1)(3x+1)=\\9x^2+3x+3x+1=\\9x^2+6x+1[/tex]

Hope this helps!

The factorized form of 9x² + 6x + 1 is indeed (3x + 1)².

To find the factorized form of the quadratic expression 9x² + 6x + 1 is (3x + 1)², we can expand the factorized form and compare it with the given expression to check if they are equal.

Expanding (3x + 1)² using the square of a binomial formula, we get:

9x² + 6x + 1

= 9x² + 3x + 3x + 1

= 3x (3x + 1) + 1 (3x + 1)

(3x + 1)² = (3x + 1)(3x + 1)

Comparing the expanded form of (3x + 1)² with the given expression 9x² + 6x + 1, we can see that they are equal.

Therefore, we have found that the factorized form of 9x² + 6x + 1 is indeed (3x + 1)².

The general form for the equation of a line is:

[tex]y = mx + c[/tex]

Where:

m is the gradient of the line

c is the y intercept of the line  (y - intercept is where the graph crosses the y-axis)

So if you had the following equation:

[tex]y = 3x + 2[/tex]

Then:

m = 3

c = 2

So gradient = 3, and y intercept = 2

---------------------------------------------------

Rearranging

So first rearrange both of the equations in the form y = mx + c :

[tex]3x + 2y = -1[/tex]   becomes  [tex]y = -\frac{3}{2} x-\frac{1}{2}[/tex]      [tex](where: \ m = -\frac{3}{2} \ and, \ c = -\frac{1}{2} )[/tex]

and:

[tex]2x+7y=2[/tex]  becomes  [tex]y=-\frac{2}{7}x +\frac{2}{7}[/tex]     [tex](where: \ m = -\frac{2}{7} \ and, \ c = \frac{2}{7})[/tex]

---------------------------------------------

The question tells us that the equation of the line we are looking for has the same y-intercept as:

[tex]2x+7y=2[/tex]

So the line we are trying to work out will also have a y intercept of   [tex]\frac{2}{7}[/tex]

(refer to rearranging)

----------------------------

The question also tells us that the line is perpendicular to  [tex]3x + 2y = -1[/tex]

Perpendicular gradient = negative reciprocal of the gradient of the line it is perpendicular to.

So the gradient of the new line will be the  negative reciprocal of the gradient of  [tex]3x + 2y = -1[/tex]

Gradient of  [tex]3x + 2y = -1[/tex]  is: [tex]-\frac{3}{2}[/tex]

(refer to rearranging)

Gradient of new line: = negative reciprocal of  [tex]-\frac{3}{2}[/tex] , which is  [tex]\frac{2}{3}[/tex]

(just flip fraction and change the sign)

------------------------------------

So for the new line: [tex]m = \frac{2}{3} \ and, \ c = \frac{2}{7}[/tex]

So just substitute in the values for m and c into: y = mx + c

[tex]y = mx + c\\y = \frac{2}{3} x + \frac{2}{7}[/tex]

-----------------------------

Answer:

So equation of the new line is:

[tex]y = \frac{2}{3}x + \frac{2}{7}[/tex]

The actual pressure when the gauge shows 33.58 would be 36.5.

Used the concept of the percentage that states,

A number or ratio that can be expressed as a fraction of 100 or a relative value indicating the hundredth part of any quantity is called a percentage.

Given that,

Ali's tire pressure gauge shows a reading which is [tex]8 \%[/tex]lower than the actual pressure.

And, the gauge shows [tex]33.58.[/tex]

Let us assume that,

The actual pressure of Ali's tires = x

Hence, we can formulate the equation,

[tex]x \times (1 - 8\%) = 33.58[/tex]

Solve the equation for x,

[tex]x \times (1 - \dfrac{8}{100} ) = 33.58[/tex]

[tex]x \times (1 - 0.08) = 33.58[/tex]

[tex]x \times 0.92 = 33.58[/tex]

Divide both sides by 0.92;

[tex]x= \dfrac{33.58}{0.92}[/tex]

[tex]x = 36.5[/tex]

Therefore, The actual pressure of Ali's tires = 36.5
