For question 9 - It is stating that AE is equal to 38. So the length of the entire line is 38. We then need to look at which figures are actually useful to us, which in this case is AC which is 10. Therefore the answer is as simple as 38-10, which gives us an answer of 28 for the other half of the line, notated as CE.

Are you trying to solve for x and y?

y=2x+1; x+2y=17
sub in one variable in the other equation.
x+2(2x+1)=17
x+4x+2=17
5x=15
x=3

now that you have x value, plug into the original equation to find y and check with the other. 
y=2(3)+1 = 7
x+2y=17 = 3 + 2(7) = 17 ; 17=17

Use the recursive formula to answer the question. What’s the 7th term in the sequence?
tensa zangetsu [6.8K]

Answer:

a7 = 36

Step-by-step explanation:

Here, we are to use the recursive formula to calculate the 7th term( we add the preceding term to 4 so as to get the succeeding term)

a1 = 12

using the recursive formula given in the question

a2 = 12 + 4 = 16

a3 = 16 + 4 = 20

a4 = 20 + 4 = 24

a5 = 24 + 4 = 28

a6 = 28 + 4 = 32

a7 = 32 + 4 = 36

Simplify (3x – 5) + (5x + 1).
Andrej [43]

Answer:

(-2x - 6)

Step-by-step explanation:

The given expression is ( 3x - 5 ) - ( 5x + 1 )

We have to simplify the given expression

First we will open the bracket having negative notation outside.

( 3x - 5 ) - 5x - 1

3x - 5 - 5x - 1

Now we will collect the similar terms together.

3x - 5x - 5 -1

-2x - 6

So the simplified form of the expression is (-2x - 6)
