x = 33
Step-by-step explanation:
2x + 1 + 4x - 19 = 180
you set to 180 assuming that that is a line and lines are = to 180 degrees

Before her hike, Lara filled her water bottle with 4 cups of water. During the hike, she drank about 10 fluid ounces every hour. Afterward, she had about 12 fluid ounces left. How many hours did she hike?
Answers
Answer:
Lara hiked for 2 hours.
Step-by-step explanation:
1 cup = 8 ounces
4 cups = 32 ounces
32 - 10h = 12
10h = 20
h = 2
Lara hiked for 2 hours.
A cup contains 8 fluid ounces so the total number of ounces that Lara had before the hike was:
= Number of cups x fluid ounces per cup
= 4 x 8
= 32 fluid ounces
After the hike, Lara was left with 12 fluid ounces which means that she consumed:
= 32 - 12
= 20 fluid ounces
She drank 10 fluid ounces per hour so the total number of hours she hiked were:
= Number of fluid ounces consumed / Fluid ounces per hour
= 20 / 10
= 2 hours

57 is greater than x - 8
Answers
This is an inequality.
This is what the statement should look like: [tex]57 > x - 8[/tex]
Now, you can actually "properly" reverse these meaning the equality sign changes too. So basically you can mirror them.
The "mirrored" inequality expression would look like this: [tex]x - 8 < 57[/tex]
Now just like normal algebra, you can transpose these terms from 1 side to another and so, -8 would transpose to the right hand side and the operation would be the inverse or in this case, addition. The expression would look something like this: [tex]x < 57 + 8[/tex]
Add them up and you get: [tex]x < 65[/tex] :D

B. y>-*x+1
C. 72-3x+1
D. y< -1x+1
Answers
The inequality is represented by the given graph is y ≤ -x/3+1.
The correct option is B.
What is inequality?An inequality is a relation that compares two numbers or other mathematical expressions in an unequal way. The majority of the time, size comparisons between two numbers on the number line are made.
We have,
A graph of an inequality, passing by (0, 1) and (3, 0).
A and D are eliminated since the line is solid.
C is disregarded because the line is shaded below as well.
Then, the inequality will be y ≤ -x/3+1
Hence, the inequality is represented by the given graph is y ≤ -x/3+1.

Slope-Intercept Form: y = mx + b
m - slope b - y-interceptParallel Lines have the same slope but different y-intercepts.
Step-by-step explanation:
Step 1: Define
y = 2x + 1
Step 2: Break function
Slope m = 2
y-intercept = 1
Step 3: Set up parallel line
y = 2x + b
8 = 2(6) + b
8 = 12 + b
b = -4
y = 2x - 4
Answer:
y = 2x - 4
Step-by-step explanation:
y - y1 = m(x - x1)
y - 8 = 2(x - 6)
y - 8 = 2x - 12
+ 12 + 12
y + 4 = 2x
- 4 - 4
y = 2x - 4 ------- formula for slope-intercept form: y = mx + b
