Answer:
1)x=6
Step-by-step explanation:
step 1: add 2x to both sides.
x−15+2x=−2x+3+2x
3x−15=3
step 2: add 15 to both sides.
3x−15+15=3+15
3x=18
step 3: divide both sides by 3.
3x/3=18/3
x=6
answer:
x=6
good luck :)
hopefully, this helps
i don't really know what it is that you need but **please let me know if this was incorrcect**
have a nice day !!
Do you need an equation?
y=2x+10
2x represents each hour, 10 represents renting fee
Answer:
B, C, and E
Step-by-step explanation:
Let's consider each option given the graph shown above:
A. The ratio of x/y can be found using any point on the line, say, (5, 6). Thus, ratio of x/y = 5/6, not 6/5.
Option A is not correct.
B. If you check for y/x for any given point along the line, we would have the same result. So the ratio of y/x is consistent. Option B is correct.
C. The graph has a line that runs through the point of origin, so therefore, it represents a proportional relationship.
Option C is correct
D. If option C is correct, then option D is not correct.
E. If option C is correct, then option E is correct.
Answer:
Step-by-step explanation:
Let's solve for 
in the first equation and then solve for 
in the second equation.
I will then use the following identity to get right of the parameter, 
:
(Pythagorean Identity).
Let's begin with .
Subtract 2 on both sides:
Divide both sides by -3:
Now time for the second equation, .
Subtract 1 on both sides:
Divide both sides by 4:
Now let's plug it into our Pythagorean Identity:
3(1)+4<span>≥ 13
7</span><span>≥ 13
No
3(2.5)+4</span><span>≥ 13
11.5</span><span>≥ 13
No
3(3)+4</span><span>≥ 13
13</span><span>≥ 13
Yes
{3, 4.5, 5}</span>
