J, (8,-3) because since they are diagonals, you can take the x and y values between the vertices and point of intersection.

For x
The distance between 2 and -4 is 6. Moving 6 in the other direction results in an x value of 8 (2+6)

For y
The distance between 5 and 1 is 4. Moving 4 in the other direction gives you a y value of -3 (1-4)

The answer is therefore (8,-3)

Y is directly proportional to x squared. if y=12 when x=2 find x when y=48

Alexxx [7]

Answer:

x = 4

Step-by-step explanation:

y = kx²

NOTE: k is constant for proportionality

putting values for x and y

if x is 2

and y is 12

12 = k(2)²

12 = k4

12 = 4k

divide both sides by coefficient of k

12÷4 = 4k ÷ 4

k=3

substitute 3 for k

therefore when

y is 48

and k is constant 3

then x will be:

48=3x²

divide both sides by coefficient of x²

48 divide by 3 = 3x² divide by 3

16=x²

take the square root of both sides

√16 = √x²

x = 4

Triangle ABC has vertices at A(−3, 4), B(4, −2), C(8, 3). The triangle translates 2 units up and 1 unit right. Which rule repres

Nataly [62]

Answer:

The translation statement is given by:

$(x,y)\rightarrow (x+1,y+2)$

After the translation, the coordinates of vertex A is (-2,6).

Step-by-step explanation:

Given :

Vertices of a triangle ABC are:

A(−3, 4), B(4, −2), C(8, 3)

The triangle is translated 2 units up and 1 unit right.

To find the co-ordinates of point A after translation.

Translation rules.

For shift of $c$ units up, the translation is given as:

$(x,y)\rightarrow (x,y+c)$

For shift of $k$ units right, the translation is given as:

$(x,y)\rightarrow (x+k,y)$

So, it says the triangles is translated 2 units up and 1 unit right.

The translation statement is given by:

$(x,y)\rightarrow (x+1,y+2)$

So, co-ordinates of point A after translation is given by :

$(-3,4)\rightarrow (-3+1,4+2)=(-2,6)$

After the translation, the coordinates of vertex A is (-2,6).

Greg made pudding every weekend. The more times he made pudding, the more practice he gained. The time he took to make the same

VashaNatasha [74]

After Greg makes the pudding 1 time, it takes him $f(1)=2(0.8) ^{1}=1.6$ hours to make it.

After Greg makes the pudding 2 times, it takes him $f(2)=2(0.8) ^{2}=1.28$ hours to make it

After Greg makes the pudding 2 times, it takes him $f(3)=2(0.8) ^{3}=1.024$ hours to make it

so The function is $f(x)=2(0.8) ^{x}$

Answer: f of x equals 2 multiplied by 0.8 to the power of x
