How do i solve using the substitution method? x+y=-1 y=-2x

leonid [27]

Answer:

$(1, -2)$

Step-by-step explanation:

Step 1: Set the second equation into the first

$x + (-2x) = -1$

$x - 2x = -1$

$-x / -1 = -1 / -1$

$x = 1$

Step 2: Solve the second equation

$y = -2(1)$

$y = -2$

ICE Princess25 [194]

Answer:

It is A

Step-by-step explanation:

2x + y = 5

y + 3 = 2x

From equation 2:

y = 2x - 3

Substituting in the first equation:

2x + 2x - 3 = 5.

A function LaTeX: f\left(x\right)=\sqrt[3]{x}f ( x ) = x 3 is transformed into the function LaTeX: g\left(x\right)=-\sqrt[3]{x}-

shtirl [24]

Answer:

A reflection in the x-axis, and a vertical translation of 8 units down

Step-by-step explanation:

The given function is

$f(x) = \sqrt[3]{x}$

The transformed function is

$g(x) = - \sqrt[3]{x} - 8$

To see the transformation that occurred, we can rewrite g(x) in terms of f(x).

That is:

$g(x) = - f(x) - 8$

Therefore f(x) is reflected in the x-axis and translated 8 units down.

The resulting graph decreases from left to right over its entire domain.

35 points What is an approximate average rate of change of the graph from x = 8 to x = 13

Ghella [55]

Rate of change is -2 because you can do rise over run to find the constant rate of change, and since you are going down you have a negative slope.
