what is the coordinate of the vertex of the parabola y-2=1/12(x+10) a. ( 10,-2) b. (-10,2) c. (-2,10) d. (2.-10)

solniwko [45]

Answer:

$y-a= c(x-b)^2$

With the vertex $V= (b,a)$

We see that b = -10 and a = 2 and then the vertes wuld be:

$V= (-10,2)$

And the best option is:

b. (-10,2)

Step-by-step explanation:

For this problem we have the following function:

$y-2 = \frac{1}{2} (x+10)$

And if we compare this expression with the general expression for a parabola given by:

$y-a= c(x-b)^2$

With the vertex $V= (b,a)$

We see that b = -10 and a = 2 and then the vertes wuld be:

$V= (-10,2)$

And the best option is:

b. (-10,2)

Which of the following is a solution of y - x < -3?

Mariulka [41]

Answer:

Option A. (6,2)

Step-by-step explanation:

We have the following inequality:

$y- x$

Solving for y we have:

$y$

The line that limits the region of inequality is

$y = x-3$

Then the region of inequality are all values of y that are less than $f (x) = x-3$

In other words, the points belonging to the inequality are all those that lie below the line.

To find out which point belongs to this region substitute inequality and observe if it is satisfied

A. (6,2)

$2$

$2$ is satisfied

B. (2, 6)

$6$

$6$ it is not satisfied

C. (2, -1)

$-1$

$-1$ it is not satisfied

The answer is the option A
