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:

Given GP with

a₄ = 4
a₅ = 7
a₁ = ?

Let the common difference is r, then

a₅ = a₄r
a₁r³ = 4
a₁r⁴ = 7

Solve for r and then a₁:

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

Equation formed:

${(x - y)}^{2} = {x}^{2} + {y}^{2} - 2xy$

Step by step explanation:

${(12)}^{2} = {x}^{2} + {y}^{2} - 2 \times 9 \\ 144 + 18 = {x}^{2} + {y}^{2} \\ = 162$

Write an equation of the line that passes through the point (2,3) with slope 3.

djyliett [7]

Answer:

Step-by-step explanation:

The slope-intercept form of an equation of a line:

$y=mx+b$

m - slope

b - y-intercept

We have the slope m = 3, and the point (2, 3).

Put the value of slope and the coordinates of the given pint (x = 2, y = 3) to the equation of a line:

$3=3(2)+b$

$3=6+b$ subtract 3 from both sides

$-3=b\to b=-3$

Finally:

$y=3x-3$
