Answer:

((1 + 2)/2 , (-2 + 5)/2) = (1.5 , 1.5)

(1.5 - 1)^2 + (1.5 - (-2))^2 = 12.5

Circle

(x - 1.5)^2 + (y - 1.5)^2 = 12.5

Answer:

y=-1/2x-3

Step-by-step explanation:

Let's pick two points for slope.

$\frac{-1+3}{-4-0}$

$\frac{2}{-4}$

For the y-inctercept, the line intersect at the y-axis at (0,-3)

CHECK:

$y=-\frac{1}{2} (-4)-3$

$y=2-3$

$y=-1$

Evaluate the function. f(x) = 3x² – x Find f(10)

kirill [66]

Answer:

Step-by-step explanation:

<u>Function Evaluation</u>

Given a function f(x) as an explicit expression, finding f(x=a) implies substituting the value of x by a in every instance it occurs.

We are given the function:

$f(x)=3x^2-x$

It's required to find f(10). We replace the x for 10:

$f(10)=3*10^2-10$

Operating:

$f(10)=3*100-10$

$f(10)=300-10$

$f(10)=290$

Thus, f(10)=290

Answer:

2, 1, 1/2, 1/4

Step-by-step explanation:

2¹ = 2

2^0 = 1

2^-¹

= 1/2¹

= 1/2

2^-2

= 1/2²

= 1/2*2

= 1/4

To complete the table

2² 2¹ 2^0 2^-1 2^-2

4 2 1 1/2 1/4

If line b is perpendicular to line a, and line c is

Nikolay [14]

Answer:

y=x-2.5

Step-by-step explanation:

If it is perpendicular to a, just like b, it has the same slope, but, it has a y-intercept of 2.5, unlike b, which has a y-intercept of 1
