Question:
The image of the question is attached below.
Answer:
x = 40
Solution:
Given ΔVDG 
ΔVNG.
DG = 207, NQ = 138, GQ = 60, QV = x
In two triangles are similar, then the measures of the corresponding sides are in proportional to each other.
Do cross multiplication, we get
Divide by 207 on both sides of the equation, we get
⇒ x = 40
⇒ QV = 40
Hence the value of x is 40.
If length AM = AK then it is isosceles.
M(-1,-6), A(-4,5)
AM=((5-(-6))²+(-4-(-1)))^(1/2)=11.401
A(-4,5) and K(5,-2)
AK=((-2-5)²+(5+4)²)^(1/2)=11.401
so the triangle is isosceles.
Answer:
Option B. 24 horses and 50 humans
Step-by-step explanation:
Let
x ----> the number of humans
y ----> the number of horses
Remember that
A human has one head and two legs
A horse has one head and four legs
so
----> equation A
-----> equation B
Solve the system by graphing
The solution of the system is the intersection point both graphs
The solution is the point (50,24)
see the attached figure
therefore
The number of humans is 50 and the number of horses is 24
Answer:
Here is a way one of my math teachers taught me.
For + x + = +:
In elementary school, you were taught by your math teacher that an positive number multiplied with a positive number is equal to a positive number. To solve, use basic rules of multiplications.
For + x - = -:
Think of it this way. There are two line segments that makes a positive sign. When multiplying, you are subtracting a line, which would result in a negative sign. Whenever a positive multiplies a negative, it is always a negative outcome.
For - x - = +:
There are two lines given (two negatives). When multiplied, the two lines make a positive sign (which is made by drawing two lines). This shows that two negative numbers multiplied or divided together will make a positive sign .
