Answer:-10
Step-by-step explanation:
Formula for mid point is :
Mid point = ( (x1+x2)÷2 , (y1+y2)÷2) )
So, X1 = 4
X2 = X
Y1 = -2
Y2 = y
Now, use the formula
(-3,1) = ( (4 + x)÷2 , (-2+y)÷2) )
Now divide the sides for yourself to solve for midpoint for X and y separately
-3 = (4+x) ÷ 2 and 1 = (-2+y) ÷ 2
This is because 3 is the x coordinate of the mid point of A and B , so we equate it to (4+x) ÷ 2 because this expression basically gives us the x coordinate of mid point of A and B. So we already have the x coordinate of midpoint which is -3 so we can use this to find X coordinate of point B
So then we solve it by multiplying the 2 with -3 which gives -6
-6 = 4+X
Shift 4 on the other side and it will become negative 4
-6-4 = X
X = -10
Answer:
B (-10,4)
Step-by-step explanation:
Given A (4,-2) and midpoint M (-3,1) we can find equation of the line
y = mx +b
slope m = raise / run
m = (y1 - y2) / (x1 - x2)
m = (-2 - 1) / (4 - -3)
m = -3 / 7 = -3/7
given the midpoint M, then point B (x,y) must have the same length and slope as AM. So point B must have twice the rise and twice the run.
Slope was -3/7 so segment AB must be 2(slope) = -6/14, so from point A, point B will be from A (4,-2)
raise = y1 - y2 = -6
-2 - y2 = -6
-y2 = -6 + 2
y2 = 4
run = x1 - x2 = 14 = 4 - x2
14 - 4 = -x2
x2 = -10
Somebody help me on A. And. B. Pleaseeee
Answer:
a. dbc = 66, ABC = 132
b. abd = 52, dbc= 52
Step-by-step explanation:
just remember that bisects means that the angles on either side of the middle line are equal. so for a, dbc = abd and ABC = 2x 66
for b, abd and dbc are equal, so both of them are just 104 divide by two

The pet store had 2 cats, 3 dogs, and 1 hamster. How many animal legs did the pet store have?
Answer:
24 legs
Step-by-step explanation:
multiple the amount of cats, dogs and hamsters by 4 and add all three answers together and u get 24
Hey there! Here's your answer.
If you mean literal legs, as in the things you use to walk, the answer would be 24.
Explanation:
First, I added all the animals up.
2 + 3 + 1 = 6
Next, I multipled the answer of the last equation by 4 because each of these animals has 4 legs.
6 x 4 = 24
Finally, I got the answer of 24.
I hope this helps!

Solve each equation. Be sure to check for extraneous solution -7= |a-3|/-2
Answer:
a = -11, 17.
Step-by-step explanation:
-7 = |a-3| / -2
Multiply both sides by -2:
|a - 3| = 14
So a - 3 = 14
Giving a = 17
or
a - 3 =- -14
giving a = -11.
Checking these values:
-7 = |17-3| / -2 = 14/-2 = -7
- so a = 17 is a solution.
-7 = |-11-3| / -2 = 14/-2 = -7
so a = -11 is also a solution.

Answer:
A
Step-by-step explanation:
All you have to do is replace the x value in the equation g(x) with whatever value x is in the tables given. An example would be as follows:
x = -2 replace x with -2
-1/2( 4(-2) + 6 )
now use pemdas to finish the equation.
you will get g(x) = 1.
Therefore, your answer is the first table, (aka A)

why do you multply by a power of 10 when writing a repeating decimal as a fraction
The goal is to multiply by a certain number (10, 100, 1000, etc.) so that when the original number is subtracted from the multiple, the repeating element cancels out. 10x = 2 is the result of multiplying by ten.
