System (a): 4 − 5 = 13 System (b): 8 − 10 = 26
3 + 6 = 11 − 11 = 2

Answers

Answer 1
Both systems have the same solution because of you simplify system B, it will become exactly the same as system A
(basically system b is 2(4x-5y=13) )

x y
-3 5
0 -1
2 ?

A.5
B.-3
C.-5
D.3

Answers

Answer: C. (2, -5 )

Step-by-step explanation:

These are the coordinates of the points on the line

We can see (-3, 5) and (0, -1) on the line.

To find the y-coordinate of a point when the x-coordinate is 2, all you have to do is look for the x-intercept of 2 and look for the y-intercept.

When you look at the bottom of the graph, you can see that the x-coordinate 2 and the y-coordinate -5 intersect to form a point.

Hope that helped!

It’s C -5

Can someone help me? I'm terrible at math lol

Answers

Answer:

D

Step-by-step explanation:

Following Pythagorean Theorom, we know a^2 + b^2 = c^2. We know b and c.  a^2 + 5^2 = 13^2.

a^2 + 25 = 169

a^2 = 144

a = √144

a = 12

So, the answer is 12, which means we pick D
