Answer:

(-1, -5)

Step-by-step explanation:

<u>Solve x + y = -6 for x</u>

$x + y = -6$

Subtract y from both sides.

$x + y - y = -6 - y$
$x = -y - 6$

<u>Substitute -y - 6 for x in 7x + y = -12</u>

<u></u> $7(-y-6)+y=-12$ <u> </u>

Simplify both sides.

$-6y - 42 = -12$

Add 42 to both sides.

$-6y - 42 + 42 = -12 + 42$
$-6y = 30$

Divide both sides by -6.

$\frac{-6y}{-6} = \frac{30}{-6}$
$y = -5$

<u>Substitute -5 for y in x = -y - 6 </u>

<u></u> $x = -(-5) -6$ <u> </u>

Simplify both sides of the equation.

$x = 5 - 6$
$x = -1$

Therefore, the answer is (-1, -5).

F (x) =2x -4; find f (-4)

NemiM [27]

Answer:

f(-4) = -12

Step-by-step explanation:

$f(x)=2x-4$

To calculate f(-4), we need to substitute x in our equation above with -4:

$f(x)=2x-4\\f(-4) = 2*(-4) - 4\\f(-4) = -8-4 = -12$

Note that 2*(-4) = -8

Answer: f(-4) = -12

Answer:

384 cm²

Step-by-step explanation:

Since it is a square pyramid, the total surface area of the pyramid is the area of its square base plus the area of its 4 triangular faces.

$\boxed{area \: of \: triangle = \frac{1}{2} \times base \times height }$

Area of a triangular face

= ½ ×12 ×10

= 60 cm²

$\boxed{area \: of \: square = side \times side}$

Base area of pyramid

= 12 ×12

= 144 cm²

∴ Surface area of pyramid

= 4(60) +144

= 240 +144

= 384 cm²

hello, John says the transformation rule (x, y) Right-arrow (x + 4, y + 7) can be used to describe the slide of the pre-image (4

oksian1 [2.3K]

Answer:John's error is that he applied the transformation rule to the image instead to the pre-image.The pre-image is the point you start with. To check the transformation rule, substitute the values of the coordinates (4, 5). This results to (4, 5) + (4+4, 5+7). Simplify to get (4, 5) → (8, 12). This is the image.
