Which expression has a value that is equivalent to 5n+13 when n=-15? n^2+13x
Answer:
the answer is 4 (option C)
Step-by-step explanation:
Since the triangles are similar, and in triangle UTV both sides are equal, we can consider QTR also has two equal sides.
therefore, the equation forms:
13x + 3 = 55
13x = 55 - 3
13x = 52
x = 52/13
x = 4

Hi there!
<u>What we need to know:</u>
- Linear equations are typically organized in slope-intercept form:
where m is the slope of the line and b is the y-intercept (the value of y when x is 0) - Parallel lines always have the same slope
<u>1) Determine the slope (m)</u>
<u />
<u />
4 is in the place of m, making it the slope. Because parallel lines have the same slope, the slope of the line is therefore 4. Plug this into
:
![y=4x+b](https://tex.z-dn.net/?f=y%3D4x%2Bb)
<u>2) Determine the y-intercept (b)</u>
![y=4x+b](https://tex.z-dn.net/?f=y%3D4x%2Bb)
Plug in the given point (6,8) and solve for b
![8=4(6)+b\\8=24+b](https://tex.z-dn.net/?f=8%3D4%286%29%2Bb%5C%5C8%3D24%2Bb)
Subtract 24 from both sides to isolate b
![8-24=24+b-24\\-16=b](https://tex.z-dn.net/?f=8-24%3D24%2Bb-24%5C%5C-16%3Db)
Therefore, the y-intercept of the line is -16. Plug this back into
:
![y=4x-16](https://tex.z-dn.net/?f=y%3D4x-16)
I hope this helps!
Answer:
The Value of c can be found using the formula 3c = 8.37. Each Baseball costs $2.79
Step-by-step explanation:
3c=8.37 divide 3c and 8.37 by 3 and it will tell you that c = 2.79.
