The domain of a function is the set of all possible x-values which will make the function “work”, and will output real
y-values

-9x=11-20
-9x= -9
x= -9/(-9)
x=1
4(2x+1)=8
2x+1=8/4
2x+1=2
2x=2-1
2x=1
x=1/2
x=0.5
5(2x+5)=-15
2x+5= -15/5
2x+5= -3
2x= -3-5
2x= -8
x= -8/2
x=-4
3(8x+1)=-21
8x+1= -21/3
8x+1= -7
8x= -7-1
8x =-8
x= -8/8

Answer: 3r + 2b = 24
r + 3b = 16
Step-by-step explanation:
Let the red blocks be represented by r
Let blue blocks be represented by b
Since 3 red blocks and 2 blue blocks weigh 24 ounces. This will be:
3r + 2b = 24
1 red block and 3 blue blocks weigh 16 ounces. This will be:
r + 3b = 16
Therefore, the equation will be:
3r + 2b = 24
r + 3b = 16
Answer:
Option B, -1/2
Step-by-step explanation:
<u>The slope is change in y over change in x.</u>
<u />
<em>Since this line is facing downward, we already know that the slope is negative.</em>
<em />
<u>To find the ratio, find the change in y and divide the change in x.</u>
<em>Change in y = -1</em>
<em>Change in x = 2</em>
<em />
<u>Change in y over change in x:</u> <em>-1/2</em>
Answer: Option B, -1/2
