Triangle XYZ has vertices X(6,-2.3) Y(7.5,5) and Z(8,4) When translated X' has coordinates (2.8, - 1.3). Write a rule to describ

Nezavi [6.7K]

To find how much that you have to translate:
X'-X
[2.8-6,-1.3-(-2.3)]
->(x-3.2,y+1)
so Y'(4.3,6) and Z'(4.8,5)

I need help with this question.

devlian [24]

We can see that $a$ lies just before 0, $b$ lies between 2 and 3m and $c$ lies between 4 and 5. So, we have

$-1 < a < 0,\quad 2 < b < 3,\quad 4 < c < 5$

In particular, this implies that

$-1+4 < a+c < 0+5 \iff 3 < a+c < 5$

So, the correct order would be

$-2,\ b,\ a+c$

Alice and her friend want to meet for lunch at a point halfway between their homes. Alice's home can be represented by the point

PilotLPTM [1.2K]

to find midpoint add the 2 x numbers and divide by 2

and add the 2 y numbers and divide by 2

X = -1 + 3 = 2, 2/2 =1

Y = 2 +4 = 6, 6/2 = 3

coordinate is (1,3)

If y varies directly as z and inversely as x and y=16 and z=2 when x=42, find y when x=14 and z=8

drek231 [11]

Answer:

y = 192

Step-by-step explanation:

Given y varies directly as z and inversely as x then the equation relating them is

y = $\frac{kx}{z}$ ← k is the constant of variation

To find k use the condition y = 16 and z = 2 when x = 42

k = $\frac{yx}{z}$ = $\frac{16(42)}{2}$ = 336

y = $\frac{336z}{x}$ ← equation of variation

When x = 14 and z = 8, then

y = $\frac{336(8)}{14}$ = 192
