Answer:

Translation

Reflection about x- axis

Step-by-step explanation:

We are given that a triangle XYZ with verticesX(-2,0),Y(-2,-1) and Z(-5,-2) undergoes a transformation to form triangle X'Y'Z' with vertices X'(4,-2),Y'(4,-3) and Z'(1,-4).

X=(-2,0) and X'=(4,-2)

x=-2,x'=4

x'-x=4-(-2)=6

y=0,y'=-2

y'-y=-2-0=-2

Y(-2,-1) and Y'(4,-3)

x'-x=4+2=6

y'-y=-3+1=-2

Z(-5,-2) and Z'(1,-4)

x'-x=1+5=6

y'-y=-4+2=-2

The vertices of triangle XYZ change into vertices of triangle X'Y'Z' by the rule

$(x,y)\rightarrow (x+6,y-2)$

Hence, the type of transformation that triangle XYZ undergoes is a translation.

Triangle X'Y'Z' undergoes a transformation to form triangle X''Y''Z'' with vertices X''(4,2),Y''(4,3) and Z''(1,4).

We can see that y- coordinate of every point of triangle X'Y'Z' change into positive and x - coordinate remain same.

Reflection about x- axis

$(x,y)\rightarrow (x,-y)$

Hence, the type of transformation that triangle X'Y'Z' undergoes is a reflection about x- axis.

Which system is equivalent to y= 9x^2 x+y=5 ?

melomori [17]

Answer : Option A

Explanation:

we can clearly see that from x+ y=5 we can substitute y = 5-x in y = 9x^2

Option B is clearly incorrect x can not be y -5

Option C is incorrect because y can not be 5 +x

Option D is incorrect because its y = 9x^2 not y^2 =9x^2 so y can not be 3x

if its y^2 = 9x^2 then only implies y = 3x

Answer:

700 Dollars

Step-by-step explanation:

The expression for solving this is I = prt

So lets start with P, that is our principal or amount of money we start with, and we want to multiply it by our rate, or r , which is 3.5, so we would do 5000 x 0.035 to get 175, then we multiply that by our time or t, which is 4 years, so 175 x 4 = 700 dollars :D

I have no idea!! Please help!!!

The area of a traingle is $\frac{1}{2}bh$
So we need to know the base and the height
To work out the sides of a right angle triangle we can use a²+b²=c
c is the hypotenuse and a and b are the other sides
Because this triangle is isoceles we know that a and b are the same

a²+b²=c²
a²+a²=c²
2a²=c²
2a²=(x√6)²
2a²=(x√6)(x√6)
2a²=x²+x√6+x√6+6
2a²=x²+x√6+x√6+6
a²= $\frac{x^{2}+x \sqrt{6}+x \sqrt{6}+6 }{2}$
a= $\sqrt{\frac{x^{2}+x\sqrt{6}+x\sqrt{6}+6}{2}}$

A= $\frac{1}{2}bh$
A= $\frac{1}{2}a*a$
A= $\frac{1}{2}$ × $\sqrt{\frac{x^{2}+x\sqrt{6}+x\sqrt{6}+6}{2}}$ × $\sqrt{\frac{x^{2}+x\sqrt{6}+x\sqrt{6}+6}{2}}$
A= $\frac{1}{2}$ × $\frac{x^{2}+x \sqrt{6}+x \sqrt{6}+6 }{2}$
A= $\frac{x^{2}+x \sqrt{6}+x \sqrt{6}+6 }{4}$
