Suppose that a1, a2, a3, . . . is an arithmetic sequence, in which a3 = 19 and a14 = 96. Find a1.
katovenus [111]
Uhhh I think you have to add 19 and 14 which shall give you the answer to a1 so it should be 33 but then I think you divide 33 and 96 or you will multiply 33 and 96

Help pls <br> 5/2x-7=3/4x+14
katrin2010 [14]

\frac{5}{2}x-7=\frac{3}{4}x+14

\frac{5x}{2}-7=\frac{3}{4}x+14\\\\\frac{5x}{2}-7=\frac{3x}{4}+14

10x−28=3x+56

10x=3x+56+28

10x=3x+84

10x−3x=84

7x=84

x=\frac{84}{7}

x=12

Hope this helps, have a blessed and wonderful day!

Determine whether each pair of lines is parallel, perpendicular, or neither.
dem82 [27]

Answer:

The are parallel lines.

Step-by-step explanation:

2x + 3y = 4

3y = -2x + 4

y = -2/3x + 4/3

10x + 15y = 2

15y = - 10x + 2

y = -10/15x + 2/15

y = - 2/3x + 2/15
