By graphing the given points, you will see that a rectangle can be made from the points. Points A and B lie on the same line horizontally as well as points C and D. To determine the distance between points, we use the distance formula expressed as:
d = √((y2-y1)^2 + (x2-x1)^2)
For points A and B, the term (y2-y1)^2 is equal to zero since they lie on the x-axis. The formula would become
d = √(x2-x1)^2
d = x2-x1 = a - 0 = a
Therefore, the distance would be equal to the value of a.
2x-x+5+3 is the answer hope this helped
Answer:
We can not solve for a unique cost for each soldier.
Step-by-step explanation:
Let x be the daily cost for legionaries and y be the daily cost for archers.
Upon using our given information we will get a system of linear equations as:
Now we will solve for x from our 2nd equation,
Now we will substitute this value in our 1st equation.
We can see that -3y cancels out with 3y and 9 is not equal to 10. So this is an unsolvable system. Therefore, we can not find a unique cost for each soldier.
Responder:
<em>a) 1
</em>
<em>b) 12
</em>
<em>c) 3
</em>
<em>d) -1 y 3
</em>
Explicación paso a paso:
Dadas las siguientes ecuaciones;
a) x²-x =0
x² = 0+x
x² = x
x = 1
b) -x²+12x = 0
-x² = -12x
x² = 12x
x = 12
c) 3x² - 9x = 0
Suma 9x a ambos lados
3x²-9x+9x = 0+9x
3x² = 9x
3x = 9
x = 9/3
x = 3
d) x²-2x-3 = 0
x²-3x+x-3 = 0
x(x-3)+1(x-3) = 0
(x+1)(x-3) = 0
x+1 = 0 y x-3 = 0
x = -1 y 3
Answer:
D. 6
Step-by-step explanation:
Suppose the triangles are similar:
The side lenghts would be proportional as follows
XZ/DF = XY/DE
12/8 = 9/x cross multiply expressions
12x = 72 divide both sides by 12
x = 6
