Answer:

No solution

Step-by-step explanation:

Given the 2 equations

y = 3x + 8 → (1)

y = - 7 + 3x → (2)

Substitute y = 3x + 8 into (2)

3x + 8 = - 7 + 3x ( subtract 8 from both sides )

3x = - 15 + 3x ( subtract 3x from both sides )

0 = - 15 ← not possible

This indicates the system has no solution

Answer: No solution

Step 1: Choose which method you would like to use to solve

Though we can solve using either substitution or elimination, we will use substitution for this one

Step 2: Substitute y for y

-7+3x=3x+8

Step 3: Subtract 3x on both sides

-7+3x=3x+8
-3x=-3x
_________
-7=8

Though we would usually use the x value to solve for y, in this case the x values canceled each other out. We are now left with 2 numbers set equal to each other, and this equation is false. Since -7 does not equal 8, the system of equation have no solution.

Hope this helps comment below for more questions :)

Consider the following sequence
wlad13 [49]

Answer:

a₇ =  2.375

Step-by-step explanation:

There is a common ratio r between consecutive terms, that is

r = \frac{-76}{152} = \frac{38}{-76} = \frac{-19}{38} = - \frac{1}{2}

This indicates the sequence is geometric with nth term

a_{n} = a₁ (r)^{n-1}

where a₁ is the first term and r the common ratio

Here a₁ = 152 and r = - \frac{1}{2} , then

a_{n} = 152 (-\frac{1}{2}) ^{n-1} , so

a₇ = 152 (-\frac{1}{2}) ^{6} = 152 × \frac{1}{64} = 2.375
