Answer:
The answer is in the image! The interval notation is [-5,4)
Step-by-step explanation:
Notice that on the linee graph it shows a open circle on 4 and a closed dot on -5... This is because the number can be greater than -5 or equal to(this is represented by the brackets) and on 4 it can only be less than 4 and not equal to it (Represented by parenthesis)...
To solve for the inequality you must solve for x. The easiest way to do this is to multiply each component in the middlee by 3, the add two on both sides, then divide by 9 on both sides. This gives you the simplest inequality at -5<= x <4!
Hope this helps! If you cant open the image let me know!
Answer:
x = 3; y = -6
Step-by-step explanation:
x - 2y = 15
2x + 4y = -18
Multiply both sides of the first equation by 2. Write the second equation below it, and add the two equations.
2x - 4y = 30
(+) 2x + 4y = -18
---------------------------
4x = 12
4x/4 = 12/4
x = 3
Now we substitute 3 for x in the first equation and solve for y.
x - 2y = 15
3 - 2y = 15
-2y = 12
y = -6
Answer: x = 3; y = -6
To solve these problems, you must make the denominators of each fraction match, before adding.
2. The answer is 11/10 or 1 and 1/10.
To find this answer, multiply 1/5 by 2/2 to get 2/10. Then add 2/10 to 9/10 get 11/10 or 1 and 1/10 as your answer.
4. The answer is 23/18 or 1 and 5/18.
To find this answer, multiply 7/9 by 2/2 to get 14/18, and multiply 1/2 by 9/9 to get 9/18. Then add 14/18 and 9/18 to get 23/18 or 1 and 5/18 as your answer.
6. The answer is 7/12.
To find this answer, multiply 1/3 by 4/4 to get 4/12 and multiply 1/4 by 3/3 to get 3/12. Then add 4/12 and 3/12 to get 7/12 as your answer.
