if segment AB is 4 units, segment AD is 23 units, and segment CD is 12 units, what is the length of segment BC?
PLEASE HELP

Answer:

a) 1

Step-by-step explanation:

3(x + 1) = -2(x - 1) +6

3x + 3 = -2x  + 2 + 6

3x + 3 = -2x + 8

Subtract 3 from both sides

3x + 3 -3 = -2x + 8 -3

          3x = - 2x + 5

Add 2x to both sides

3x + 2x  = -2x + 5 +2x

        5x =  5

Divide both sides by 5

 5x/5 = 5/5

x = 1

Answer:

-7 is less than or equal to 0

Step-by-step explanation:

range is looking at the correlation on the graph from left to right. At -7, there is a dot and at 0, there is a dot. The graph is not continuous, so that is the answer.

===================================================

Explanation:

Everywhere you see an x, replace it with -5. Then use the order of operations PEMDAS to simplify

[tex]f(x) = -x^2 - 7x - 5\\\\f(-5) = -(-5)^2 - 7(-5) - 5\\\\f(-5) = -(25) - 7(-5) - 5\\\\f(-5) = -25 + 35 - 5\\\\f(-5) = 10 - 5\\\\f(-5) = 5\\\\[/tex]

Keep in mind that for the x^2 term, you are squaring all of x = -5, which includes the negative as well. So that means

x^2 = (-5)^2 = (-5)*(-5) = 25

but sticking a negative out front makes

-x^2 = -(-5)^2 = -25

Answer:

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

Step-by-step explanation:

Take the given equation:

[tex]-3x+2y=6[/tex]

Solve for y so that the equation is written in slope-intercept form:

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

m is the slope and b is the y-intercept. x and y are the coordinate points (x,y).

Solve for y:

Add 3x to both sides of the equation:

[tex]-3x+3x+2y=6+3x\\\\2y=3x+6[/tex]

Divide both sides of the equation by 2 to isolate y:

[tex]\frac{2y}{2}=\frac{3x+6}{2} \\\\ y=\frac{3}{2}x+3[/tex]

The slope is [tex]\frac{3}{2}[/tex] and the y-intercept is 3.

To graph, you need two points. You can use the y-intercept as one.

The y-intercept is the place where the line crosses over the y-axis, where x equals 0, so the point is (0,3).

Next, take any value for x and insert it into the equation. We'll use 2:

[tex]y=\frac{3}{2}(2)+3[/tex]

Using this, you can solve for the value of y when x is equal to 2.

Simplify:

[tex]\frac{3}{2} *\frac{2}{1}=\frac{6}{2}=3 \\\\y=3+3\\\\y=6[/tex]

So, when x=2, y is 6 (2,6).

Plot the points (0,3) and (2,6)

Draw a straight line through the two, going past both.

Hey there! :)

Answer:

[tex]\huge\boxed{n = 25}[/tex]

-1/5n + 7 = 2

Start by subtracting 7 from both sides:

-1/5n + 7 - (7) = 2 - (7)

-1/5n = -5

Multiply both sides by the reciprocal of -1/5, or -5.

(-5) · (-1/5n) = (-5) · (-5)

[tex]\frac{5}{7}:\quad 0.71428\\\\= 0.71\\\\\frac{0.71}{1}\times \frac{100}{100}\\ \\= 71/100\\\\= 71\%[/tex]

Step-by-step explanation:

The fraction 5/7 is equal to 0.7 or 70%.

To convert 5/7 to a decimal,

divide the numerator (5) by the denominator (7):

So, 5 ÷ 7 = 0.71428571...

Rounded to the nearest tenth, the decimal equivalent of 5/7 is 0.7.

Now, to convert 0.7 to a percent, we multiply it by 100:

0.7 x 100

= 70%

Therefore, when rounded to the nearest tenth, 5/7 is equal to 0.7 or 70%.

Answer:

(x - 12)² + y² = 100

Step-by-step explanation:

The standard form of the equation of a circle is;

(x - a)² + (y - b)² = r²

where:

a and b are the coordinates of the centre of the circle

r is the radius

We are given the coordinates of the endpoints of the diameter as; (22,0) and (2,0)

Thus, the centre of the circle would be at the mid point of the endpoints of the diameter.

Coordinates of the centre is;

((22 + 2)/2), (0 +0)/2))

This is;

(12, 0)

So, a = 12 and b = 0

Now,to get the radius r, we will use the formula;

r = √[(x2 - x1)² + (y2 - y1)²]

Where;

(x1, y1) and (x2, y2) are 2 points namely (12,0) and (22, 0)

r = √[(12 - 22)² + (0 - 0)²]

r = √(-10)²

r = √100

r = 10

Thus,equation of the circle is;

(x - 12)² + (y - 0)² = 10²

(x - 12)² + y² = 100

Answer:

Option B.

Step-by-step explanation:

We know that, if the graph of a function is reflected across the line y=x, then we get the graph of inverse of that function.

It means, the graph of inverse function is the mirror image of graph of function across the line y=x.

If h(x) is a function and h⁻¹(x) is its inverse function, then the line y = x is the perpendicular bisector of each segment connecting a point on h(x) to the corresponding point on h⁻¹(x).  

Therefore, the correct option is B.

Step-by-step explanation:

[tex]y-2=-3(x-4)\\\\y-2=-3x+12\\\\y-2+2=-3x+12+2\\\\\boxed{y=-3x+14}[/tex]

First distribute the -3 through the parenthses

which gives us y - 2 = -3x + 12.

Move the number to the right side of the equation

by adding 2 to both sides to get y = -3x + 14.

Notice that the equation above is written in slope-intercept form because

the y term is isolated or by itself on the left side of the equation.

(I/175.393) + 0.663 = r

We are given r = 23.6%

Plugging this vakue in for r gives;

l/175.393 + 0.663 = 23.6

l/175.393 = 23.6 - 0.663

l/175.393 = 22.937

I = 175.393 x 22.937

I = $4022.99, which is approximately
