Maria compared the slope of the function f(x)=(-6x-21) to the slope of the linear function that fits the values in the table bel

raketka [301]

Answer:

b. both functions have a negative slope

Step-by-step explanation:

The given function is

$f(x)=-6x-21$

This function is of the form $y=mx+b$ , where $m=-6$ is the slope and $b=-21$ is the y-intercept.

We can also determine the slope of the function in the table using any two points, say $(0,7)\:and\:(2,6)$ .

The slope formula is given by,

$m=\frac{y_2-y_1}{x_2-x_1}$ .

If $(x_1,y_1)=(0,7)\:and\:(x_2,y_2)=(2,6)$ , then,

$m=\frac{6-7}{2-0}$

$m=-\frac{1}{2}$ .

We can see that both functions have a negative slope.

The correct answer is B.

1/2y+2/5=4 2/5 how do I solve this matter

Inessa [10]

Answer:

y =8

Step-by-step explanation:

1/2y+2/5=4 2/5

Subtract 2/5 from each side

1/2y+2/5-2/5=4 2/5-2/5

1/2 y = 4

Multiply each side by 2

1/2y *2 = 4*2

y = 8
