A₁ = 3
a₂ = 4.2

d = a₂ - a₁
   = 4.2 - 3
   = 1.2

a₉₈ = a₁ + d(n-1)
      = 3 + 1.2(98-1)
      = 3 + 1.2×97
      = 3 + 116.4
      = 119.4

Which equation represents a proportional relationship? Y=-5(x+1). Y=5x+1. Y=-x. Y=1/5x
Tema [17]
A proportional relationship is also a direct variation.
The general equation of direct cvariation is

y = kx,

where k is a number.

In your case, if k = -1, then y = kx becomes y = (-1)x which is the same as

y = -x

What value of x will make the given triangles congruent?
Molodets [167]
Because you're trying to make them congruent, equal the two expressions to each other. 

So, for #10 you would equal them so it would look like this. 
2x+2=5x-19

Then you would just go ahead and simplify

2x+2=5x-19
-2x     -2x
---------------
2= 3x -19
+19    +19
---------------
21=3x
---  ----
3     3

x=7

This means that x should be 7. You can check this just by plugging it in

2x+2
2(7)+2 = 16

5x-19
5(7)-19= 16

Same with #11.

x+8=3x-14
-x     -x
--------------
8=2x-14
+14   +14
--------------
22=2x
---  ----
2     2

x=11

Check. 

x+8
11+8= 19

3x-14
3(11) - 14 = 19

The first term of an arithmetic sequence is -3 and the fifteenth term is 53. What is the common difference of the sequence?
Maru [420]

C: 4 is the right answer

Step-by-step explanation:

Given

a1 = -3

a15 = 53

We know that explicit formula for the arithmetic sequence is:

a_n=a_1+(n-1)d

For the 15th, term it will be

a_{15}=-3+(15-1)d\\53=-3+14d

Adding 3 on both sides

53+3 = -3+3 + 14d\\56 = 14d

Dividing both sides by 14

\frac{56}{14}=\frac{14d}{14}\\d=4

Hence,

C: 4 is the right answer
