Find the slope of the line y = 5x + 4.

avanturin [10]

Answer:

x=1/5y+−4/5

Step-by-step explanation:

Let's solve for x.

y=5x+4

Step 1: Flip the equation.

5x+4=y

Step 2: Add -4 to both sides.

5x+4+−4=y+−4/5x=y−4

Step 3: Divide both sides by 5.

5x/5=y−4/5x=1'5y+−4'5

Answer:

x=1/5y+−4/5

A geometric sequence has a4 = 4 and a5 = 7. What is a1 ? Your answer

svetlana [45]

Answer:

4⁴/7³ or 256/343

Step-by-step explanation:

<u>Given GP with </u>

a₄ = 4
a₅ = 7
a₁ = ?

<u>Let the common difference is r, then</u>

a₅ = a₄r
a₁r³ = 4
a₁r⁴ = 7

<u>Solve for r and then a₁:</u>

4r = 7 ⇒ r = 7/4
a₁(7/4)³ = 4
a₁ = 4*(4/7)³ = 4⁴/7³ = 256/343
