Answer: It means find the slope of each line.

Step-by-step explanation:

A is the line that runs from 0,-6 to 5,14 This is tricky because the scale of the y-axis is twice the value of the x-axis. So what looks like a slope (gradient) of +2 is actually +4. Figure the difference in y-values divided by the difference in x-values.

Same for line B.

I used 0 - 14 for the rise, and 4 -(-3) for the run. 7/-14 makes that slope a -2. That's negative two, not the apparent negative one!

Answer:

Mean: 16; Mode: 15

Step-by-step explanation:

I did it.

Answer:

I think the mean is 16.

The mode is 15 because it is the most seen number in the data set.

Step-by-step explanation:

Add then divide for the mean (add all numbers, then divide by how many numbers there are).

The mode is the one that you see the most.

Answer:

-7 ≤ x

Step-by-step explanation:

4x – 12 ≤ 16 + 8x

Subtract 4x from each side

4x-4x – 12 ≤ 16 + 8x-4x

– 12 ≤ 16 + 4x

Subtract 16 from each side

-16 – 12 ≤ 16 -16+ 4x

-28  ≤  4x

-28  ≤ 4x

Divide each side by 4

-28/4 ≤ 4x/4

-7 ≤ x

An equation is a mathematical statement that is made up of two expressions connected by an equal sign.

The value of x after solving the equation is 1.

An equation is a mathematical statement that is made up of two expressions connected by an equal sign.

Example:

2x + 3 = 4 is an equation

3x + 5 = 3 is an equation

We have,

3x + 2 = (2x + 13) / 3

Multiply both sides by 3.

3 x (3x + 2) = 2x + 13

Remove the parentheses.

(3 x 3x) + 3 x 2 = 2x + 13

9x + 6 = 2x + 13

Subtract 2x on both sides.

9x + 6 - 2x = 13

7x + 6 = 13

Subtract 6 on both sides.`

7x + 6 - 6 = 13 - 6

7x = 7

Divide 7 on both sides.

x = 1

Thus,

The value of x after solving the equation is 1.

Answer:

Step-by-step explanation:

perfect square  (a - b)^2 = a^2 - 2ab + b^2

In this case

20x = 2 * x * 10

and

10^2 = 100

so

(x - 10)^2 = x^2 - 20x + 100

Therefore, the missing constant term is 100

The answer is A

If you plot them on a graphing calculator you can see that the diameter is around 9ish. So point J is inside the circle.

Answer:

Step-by-step explanation:

First look at the tangent function f(x) = tan x.  Its domain is restricted:  (-pi/2, pi/2).  There are no restrictions on the function value, so the range is (-infinity, +infinity).  The primary interval on which tan x is defined is (-pi/2, +pi/2, which has length pi.

In comparison, the domain of f(x) = tan 2x is only half as long as that of f(x) = tan x:  (-pi/4, +pi/4), with length pi/2.

Now, focusing on f(x) = 3cot(2x):  the range is the same:  (-infinity, +infinity).  The period is half that of tan x:  pi/2 instead of pi.  Remember that the cotangent function repeats itself every pi/2 radians.

Domain:  (-pi/4, +pi/4) (centered on the origin), (-3pi/4. 3pi/4), and so on, continuing to both the left and the right.

Range:  (-infinity, infinity)

Answer:

B. (-7,-3)

Step-by-step explanation:

Given the circle: [tex](x + 7)^2 + (y - 10)^2 = 13^2[/tex]

The point (x,y) which lie on the circle are the coordinate which satisfies the given equation of the circle.

We now consider the given options.

Option A (5,12)

When x=5, y=12

[tex](5 + 7)^2 + (12 - 10)^2 =12^2+2^2=148\neq 169= 13^2[/tex]

Option B (-7,-3)

When x=-7, y=-3

[tex](-7 + 7)^2 + (-3 - 10)^2 =0^2+(-13)^2= 169=13^2[/tex]

Option C (-6,-10)

When x=-6, y=-10

[tex](-6 + 7)^2 + (-10 - 10)^2 =1^2+(-20)^2=401\neq 169= 13^2[/tex]

Option D (6,23)

When x=6, y=23

[tex](6 + 7)^2 + (23 - 10)^2 =13^2+13^2=338\neq 169= 13^2[/tex]

We can see that only (-7,-3) satisfies the equation of the circle. Thus it is the point which lies on the circle.

The correct option is B.

Answer:

A. 260°

Step-by-step explanation:

The measure of the arc in the circle given is 260°

A circle is the set of all points in the plane that are a fixed distance (the radius) from a fixed point (the centre). Any interval joining a point on the circle to the centre is called a radius. By the definition of a circle, any two radii have the same length.

Given is a circle, with an inscribed angle of 50°, we need to find the arc ABC,

So, according to the inscribed angle theorem,

∠ BAC = 1/2 arc BC

So, arc BC = 2 x ∠ BAC

arc BC = 2 x 50

∠ BAC = 100°

Now,

arc ABC = 360° - arc BC

Since, we know that the whole circle, measures 360°

So,

arc ABC = 360° - 100°

arc ABC = 260°

Hence, the measure of the arc in the circle given is 260°

Answer:

x^2+9x+20

Step-by-step explanation:

Answer:

The answer is true

Step-by-step explanation:

Answer:

SV = 41 units

QT = 21 units

Step-by-step explanation:

Please refer to the attached figure.

It is given that line segment TV has a perpendicular bisector as line N which intersects on line on TV at point R.

So, TR = RV

We are given that:

[tex]RV = 3 x + 2\\QV = 4 x + 1\\TS =9 x -4 \\TR = 17\ units[/tex]

Comparing the values of TR and RV:

[tex]3x +2=17\\\Rightarrow x = 5[/tex]

We can easily observe that due to the nature of the construction of this figure there is symmetry present.

As a result, we can draw the following conclusions:

1. [tex]QT = QV = 4x+1\\[/tex]

Putting value [tex]x=5[/tex]:

[tex]QT = 4\times 5+1\\\Rightarrow QT =21\ units[/tex]

2. [tex]TS =SV = 9x-4[/tex]

Putting value [tex]x=5[/tex]:

[tex]\Rightarrow SV = 9 \times 5-4\\\Rightarrow SV = 41\ units[/tex]

Hence the values are:

SV = 41 units

QT = 21 units

Answer:

41,21

Step-by-step explanation:

Answer:

[tex]I=\frac{P}{V}[/tex]

Step-by-step explanation:

We are given the equation [tex]P=I*V[/tex], and we need to solve the equation for [tex]I[/tex]. Solving an equation for a variable means that we manipulate the equation so it is in the form (variable being solved for) = ?, where the ? is any expression.

To solve for [tex]I[/tex], we need to isolate the variable. This is the process of getting the equation into the form mentioned above by essentially getting all [tex]I[/tex] terms on one side and all [tex]\text non-I[/tex] terms on the other side.

In this case, we need to "get rid" of the [tex]V[/tex] from the right-hand side (RHS). Notice that it is being multiplied by the variable we are solving for. Therefore, to remove it from the RHS, we will need to perform the opposite operation, which is division. We will use what's called the Division Property of Equality to do this, which states that in order to maintain equality, you need to divide both sides of an equation by the same number.

Dividing both sides by [tex]V[/tex], we get:

[tex]P=I*V[/tex]

[tex]\frac{P}{V}=\frac{I*V}{V}[/tex]

[tex]\frac{P}{V} = I[/tex] (simplify RHS)

[tex]\bf I=\frac{P}{V}[/tex] (this uses the Symmetric Property of Equality - if a = b then b = a)
