What is the equation of this line?
elena-14-01-66 [18.8K]

Answer:

A) y = 4/3 x - 1/3

Step-by-step explanation:

(4,5) and (-2,-3)

Slope = (5 + 3)/(4 + 2)

= 8/6

= 4/3

Equation

y + 3 = 4/3(x + 2)

y + 3 = 4/3 x + 8/3

y = 4/3 x + 8/3 - 9/3

y = 4/3 x - 1/3

y = 4/3 x - 1/3

Solve the following exponential equations.<br> 10^(3x−5) = 7^x
zalisa [80]

Answer:

x = 2.3202

Step-by-step explanation:

Given equation:

10^{(3x-5)} = 7^x

on taking log both sides, we get

\log(10^{(3x-5))} =\log(7^x)

now,

using the property of log function

log(aᵇ) = b × log(a)

therefore,

we get

(3x-5)log(10) = xlog(7)

now,

log(10) = 1

and

log(7) = 0.84509

thus,

( 3x - 5 ) × 1 = 0.84509x

or

3x - 0.84509x - 5 = 0

or

2.15491x = 5

or

x = 2.3202
