Answer:

Domain: -4 < x < 4

Zeros: (-2, 0), (0, 0) and (2, 0)

The function is positive if: 0 < x < 2

The function is negative if: -4 < x < 0 and 2 < x < 4

Step-by-step explanation:

Domain of the function are those x values where the function is defined, For this case, -4 < x < 4

Zeros of a function are those x values where y = 0, that is, the graph intersect x-axis. For this case, the points are: (-2, 0), (0, 0) and (2, 0)

The function is positive if the graph o the function is above x-axis. For this case, the function is positive at the interval (0, 2)

The function is negative if the graph o the function is below x-axis. For this case, the function is negative at the intervals (-4, 0) and (2, 4)

What is an equation of the line that passes through the points (0, -4) and (-4, 6)?
olganol [36]

Answer:

The equation of the line is.

y=-\frac{5}{2}x-4

Step-by-step explanation:

Given:

The given points are (0, -4) and (-4, 6)

The equation of the line passing through the points (x_{1},y_{1}) and (x_{2},y_{2}) is.

\frac{x-x_{1}}{x_{2}-x_{1}}=\frac{y-y_{1}}{y_{2}-y_{1}}

Thus, the equation of the line that passes through the points (0, -4) and (-4, 6) is

\frac{x-0}{(-4)-0}=\frac{y-(-4)}{6-(-4)}

\frac{x}{-4}=\frac{y+4}{6+4}

-\frac{x}{4}=\frac{y+4}{10}

-\frac{10x}{4}=y+4

-10x=4(y+4)

-10x=4y+16

4y=-10x-16

The above equation is divided by 2 both sides.

2y=-5x-8

y=-\frac{5}{2}x-4

Therefore, the equation of the line that passes through the points (0, -4) and (-4, 6) is y=-\frac{5}{2}x-4

Carmen simplifies the expression (4 y 8 x 6) 25 (4 x 6 y 7). The coefficient of the variable y in her simplified answer is 4. 6.
Sever21 [200]

Carmen simplifies the expression and gets the coefficient of y is 10. Thus, the correct option is C.

<h3>What is simplification?</h3>

Simplification is to make something easier to do or understand and to make something less complicated.

Given

Carmen simplifies the expression \rm (4 y + 8 x + 6) + 25 + (4 x  +6 y +7).

We can add x term with x, y term with y, and constant with constant.

On simplifying, we have

\rm (4 y + 8 x + 6) + 25 + (4 x  +6 y +7)\\\\12x + 10y + 38

Thus, the coefficeint of y is 10.

More about the simplification link is given below.

Use inverse operations to solve each equation.
omeli [17]
1) -2x = 34
The inverse of multiplication is division, so divide both sides by -2.
x = -17

2) y - 3.5 = -2.1
The inverse of subtraction is addition, so add 3.5 to both sides.
y = 1.4

3) 2/3z = -6
The inverse of division is multiplication, so multiply both sides by 3z
2 = -18z
z = -1/9
