-5x=25 how to solve this problem ​
Sidana [21]
X = -5

The goal of this problem is to solve for x.

To solve x in this problem you need to find a way to get it by itself on the left side, the way to do this is divide -5x by -5.

You then also have to do the same for the right side. This gives you -5.

gladu [14]

Answer:

g(-2)=3

g(0)=-5

g(3)=2

Step-by-step explanation:

g(-2)= -2(-2)+ 3(-2) - 5

4-6-5

2-5

g(-2)=3

g(0)= -2(0) + 3 (0)-5

0+0-5

g(0)=-5

g(3)= -2(3) + 3(3)-5

-6+9-5

3-5

g(3)=2

A number, x, rounded to 2 significant figures is 1300<br>Write down the error interval for x.​
nikitadnepr [17]

Answer:

[1250,1350).

Step-by-step explanation:

It is given that a number, x, rounded to 2 significant figures is 1300.

It is possible if,

1. The value of x is greater than of equal to 1250 and less than or equal to 1300.

i.e., 1250\leq x\leq 1300     ...(1)

2. The value of x is greater than of equal to 1300 and less than 1350.

i.e., 1300\leq x       ...(2)

On combining (1) and (2), we get

1250\leq x < 1350

1350 is not included in the error interval for x.​

Interval notation is [1250,1350).

Therefore, the error interval for x is [1250,1350).
