Answer:

y+3= -4x

Step-by-step explanation:

general equation is (y-y1) = m(x-x1)

m=rise/run= -4/1 (is negative because looking from left to right on the graph it goes downward)

pick any point on the line to put in. the equation for example (0,-3)

y+3= -4x

Answer:

Angle BDC is an inscribed angle.

The inscribed angle equals one half of the intercepted arc.

Therefore, the intercepted arc equals 130 degrees.

Hannah has a grid of squares that had 12 rows with 15 squares in each row. She colors 5 rows of 8 squares in the middle of the g

arlik [135]

there's a grid of squares with 12 rows and in each row there are 15 squares

from this grid she colours 8 squares from each row for 5 rows blue.

the rest of the squares she colours red

so first we have to find how many squares are there in the grid in total

so if each row has 15 squares

then 12 rows have - 15 x 12 = 180 squares

blue coloured squares

she colours 8 rows of 5 squares

so if 1 row has - 5 squares

then 8 rows have - 5 x 8 = 40 squares

from 180 squares, she colours 40 squares blue and the rest red colour

therefore the squares she colours red are

red squares = 180 - 40 = 140 squares

she colours 140 squares red

1. Describe the transformations necessary to transform the graph of

lana66690 [7]

Answer:

- The function $f(x)$ must be shifted right 1 unit.

- The function $f(x)$ must be shifted up 4 units.

- The function $f(x)$ must be stretched vertically by a factor of 3.

Step-by-step explanation:

There are some transformations for a function f(x):

If $f(x)+k$ , then the function is shifted up "k" units.

If $f(x)-k$ , then the function is shifted down "k" units.

If $f(x+k)$ , then the function is shifted left "k" units.

If $f(x-k)$ , then the function is shifted right "k" units.

If $bf(x)$ and $b>1$ , then the function is stretched vertically by a factor of "b".

If $bf(x)$ and $0$ , then the function is compressed vertically by a factor of "b".

In this case we have the following parent function $f(x)$ :

$f(x)=x^2$

And the function $g(x)$ :

$g(x) = 3(x - 1)^2 + 4$

Based on the explained before, we can describe the transformations necessary to transform the graph of $f(x)$ to the graph of $g(x)$ :

- The function $f(x)$ must be shifted right 1 unit.

- The function $f(x)$ must be shifted up 4 units.

- The function $f(x)$ must be stretched vertically by a factor of 3.

Geometry is super hard

alukav5142 [94]

Reflection across the line, y=-x or x=-y

basically, for every x, switch it for y and times -1
for every y switch it for x and tiimes -1

in short, switch the x and y and times both by -1

vertex is(1,-3)
switch
(-3,1)
times -1 to both
(3,-1)
