What is the converse of the following conditional?If a point is in the first quadrant, then its coordinates are positive

a. If a point is in the first quadrant, then its coordinates are positive
b. If the coordinates of a point are positive, then the point is in the first quadrant
c. If the coordinates of a point are not positive, then then the point is not in the first quadrant
d. If a point is not in the first quadrant, then the coordinates of the point are not positive.

Answers

The answer is B because the converse just flips the two phrases within the statement.

Answer:

b. If the coordinates of a point are positive, then the point is in the first quadrant

Five times a number is the same as 30 more than 8 times the number. Find the number.If n is "the number," which equation could be used to solve for the number?

3n = 30
5n + 8n = 30
5n = 8n + 30

Answers

Answer:  the correct option is

(C) 5n=8n+30.

Step-by-step explanation:  Given that five times a number is the same as 30 more than 8 times the number.

We are to find the number.

Also, if the number is denoted by n, then we are to select the equation that could be used to solve for the number.

Since n is the given number, so five times the number is written as

5* n=5n.

Also, 30 more than eight times the number is written as

8* n+30=8n+30.

Since both the expressions are same, so we get

5n=8n+30\n\n\Rightarrow 8n-5n=-30\n\n\Rightarrow 3n=-30\n\n\Rightarrow n=-(30)/(3)\n\n\Rightarrow n=-10.

Thus, the required number is -10 and the the equation that is used to solve for the number is 5n=8n+30.

Option (C) is CORRECT.

Its the last one .. 5n=8n + 30 

On a coordinate plane, a parabola opens up in quadrant 1. It goes through (2, 12), has a vertex at (5, 3), and goes through (8, 12). Write the equation of the function whose graph is shown. y = (x + )2 +.

Answers

Answer:

Step-by-step explanation:

You have a vertex coordinate and 2 points. In order to write the equation for that parabola, you only need the vertex and one point. We will fill in the following work form of the parabola:

y=a(x-h)^2+k , where h and k are from the vertex and x and y are from the point. Filling in:

12=a(8-5)^2+3 and

12=a(3)^2+3 and

12=9a+3 and

9 = 9a s0

a = 1.

Now we can write the equation, filling in a, the only unknown we had, which we now know is 1:

y=1(x-5)^2+3

Answer:

y =  1(x +  -5)2 + 3
