Answer:

(−4, −8), because the point satisfies both equations

Step-by-step explanation:

Line A  

y = x - 4

Line B

y = 3x + 4

If we equate those 2 equations

x - 4 = 3x + 4

2x = -8

x = -4

y = -8

Answer:

C. (-4,-8), because the point satisfies both equations

Step-by-step explanation:

You need to graph both equations. For line A, the y-intercept is -4, so you plot a point on -4. The slope is one, so you rise up one and run right 1. For line B, the y-intercept is 4, so you plot a point on 4. The slope is 3, so you rise up 3 and run right 1. Then, you look for where the 2 lines intersect. In this case, line A and line B intersect at the point (-4,-8).

Lorico [155]

Answer:

3142 feet

Step-by-step explanation:

first, find the circumference of the wheel.

approx 75.4

every one rotation you travel approximately 75.4 inches

75.4 x 500 =37,700

37,700/12 = feet traveled

3141.6... feet

Ok So I an taking algebra 1 and this question is really confusing me.
V125BC [204]
You use the arithmetic sequence formula and input the information given to you.
tn = a + (n-1)d
t(56) is what your looking for so don't worry about the tn.
a is your first term,
a = 15.
n is the position of the term you are looking for, n = 56.
And d is the common difference, you find this by taking t2 and subtracting t1. t2=18 and t1=15.
d = 18 - 15 = 3
Inputting it all into the formula you get,
t(56) = 15 + (56-1)(3)
term 56 = 180.
You use this formula to find any term in a sequence provided you are given enough info. You can also manipulate it if you are asked to find something else like the first term(a), common difference(d) or term position(n). It just depends on what the question is asking and what information you are given. :)
Hope this helps!
