Consider the given line segment. If AC is 39cm long, answer the following questions:
A
B
9x+7
-3x+20
AB -
BC =
Is point B the midpoint? (yes or no)
The point which is equidistant from the endpoints of a line segment, hence, marking the middle point of the line is called the midpoint. Therefore, Point B is not the midpoint
AB + BC = AC
9x + 7 + (-3x + 20) = 39
9x + 7 - 3x + 20 = 39
6x + 27 = 39
6x = 39 - 27
6x = 12
x = 12 / 6
x = 2
9x + 7 = - 3x + 20
9(2) + 7 = - 3(2) + 20
25 = 15
Hence,
Since, AB ≠ BC, then B is not the midpoint

Find the inverse of the following
F(x)=-3/4x+6
Answer:
[tex] {f}^{ - 1} (x)= - \frac{4}{3} x + 8[/tex]
Step-by-step explanation:
[tex]f(x) = - \frac{3}{4} x + 6[/tex]
[tex]y = - \frac{3}{4} x + 6[/tex]
[tex]x = - \frac{3}{4} y + 6[/tex]

What is the midpoint of AB ?
B
Answer:
hope it helps you........
Step-by-step explanation:
The midpoint formula is
[tex] (\frac{x1 + x2}{2} ) \: and \: ( \frac{y1 + y2}{2} )[/tex]
Where (x1,y1) is one pair of the points and (x2,y2) is the other pair of points.
The points are
(-5,-4)
(-3,3) So the midpoint is
[tex]( \frac{( - 5 + ( - 3)}{2} )\: and \:( \frac{ - 4 + 3}{2} )[/tex]
Which gives us
[tex] - 4 \: and \: - 0.5[/tex]
So the midpoint is
(-4,-0.5)

Answer:
the first one: The coordinates of A' are (-2, 3)
and the last one: The coordinates of B' are (-2, 0) and the coordinates of C' are (2, -1).
Step-by-step explanation:
when you rotate a triangle counterclockwise by 90° you swap the numbers of the x and y coordinates.
like how the coordinates of B' were (0, 2) and became (-2,0) once the triangle was rotated.

What is the common difference of the following sequence? 27, 11, -5, -21, -37, . . .
Answer:
Find the common difference and the next term of the following sequence:
3, 11, 19, 27, 35...
Step 1. To find the common difference, subtract any consecutive pair of terms.
11 - 3 = 8
19 - 11 = 8
27 - 19 = 8
35 - 27 = 8
The difference is always 8, so d = 8.
Step 2. Use the common difference to find the next term.
Since the last term was 35, adding the common difference of 8 will find the next term. The next term is 35 + 8 or 43.
Step-by-step explanation:
mark me brainliest plz
Answer:
[tex]d = a_{2} - a _{1}[/tex]
d is the common difference
a1 is the first term, a1 = 27
a2 is the second term, a2 = 11

[tex]d = 11 - 27 \\ { \boxed{ \boxed{d = - 16}}}[/tex]
what numbers have a sum of 20 and the difference is 4
Answer:
16 and 2
Step-by-step explanation:
I'm not sure honestly if this is correct, but I hope this helps.
Answer:
The numbers are 12 and 8
Step-by-step explanation:
let the numbers be x and y :
[tex]x + y = 20 - - - (a) \\ x - y = 4 - - - (b)[/tex]
add (a) and (b):
[tex]2x + 0y = 24 \\ 2x = 24 \\ x = 12[/tex]
find y:
[tex]x + y = 20 \\ 12 + y = 20 \\ y = 20 - 12 \\ y = 8[/tex]

I need the answer to this question
Answer:
y = 3/4x + 19/2
Step-by-step explanation:
m = 3/4. point (-6,5)
Point slope form:
y-5=3/4(x- -6)
y -5 = 3/4x + 18/4. 18/4 = 9/2
Y = 3/4x + 9/2 + 5. 5 times 2 plus 9 over 2 = 19/2
y = 3/4x + 19/2

Answer:
[tex]x=-\frac{5}{3}\quad \mathrm{or}\quad \:x=3[/tex]
Step-by-step explanation:
[tex]2\left|3x-2\right|=14[/tex]
⇒ Divide both sides by 2
[tex]\frac{2\left|3x-2\right|}{2}=\frac{14}{2}[/tex]
[tex]\left|3x-2\right|=7[/tex]
⇒ Now, apply absolute rule:- if |x|=a,a > a than x=a or x=-a
[tex]3x-2=-7\quad[/tex]
or...
[tex]3x-2=7[/tex]
Now,
[tex]3x-2=-7[/tex]
⇒ Add 2 to both sides:-
[tex]3x-2+2=-7+2[/tex]
[tex]3x=-5[/tex]
⇒ Divide both sides by 3:-
[tex]\frac{3x}{3}=\frac{-5}{3}[/tex]
[tex]x=-\frac{5}{3}[/tex]
[tex]3x-2=7[/tex]
⇒ Add 2 to both sides:-
[tex]3x-2+2=7+2[/tex]
[tex]3x=9[/tex]
⇒ Divide both sides by 3:-
[tex]\frac{3x}{3}=\frac{9}{3}[/tex]
[tex]x=3[/tex]
