The equation of a line is y = 3x + 8 what is the gradient of the line

Answers

Answer 1

Answer:

Answer: 3

Step-by-step explanation:

We can find the gradient, or slope, of the line by looking at the equation. This equation is given in slope-intercept form equation which is y = mx + b, where m is the gradient/slope.

y = 3x + 8

y = 3x + 8 ➜ the gradient is 3

Answer 2

Answer:

The gradient of the line is 3.

How to find the gradient

The equation of line given is y = 3x + 8.

To find the gradient of the line, compare it with the standard slope-intercept form y = mx + b, where m is the gradient (slope).

Comparing the equations:

m (gradient) = 3

Hence, the gradient of the line is 3.

14(0.89)^x+4.5 =162

Answers

$14(0.89)^(x + 4.5) = 162$
$(14(0.89)^(x + 4.5))/(14) = (162)/(14)$
$0.89^(x + 4.5) = 11(4)/(7)$
$ln(0.89^(x + 4.5)) = ln(11(4)/(7))$
$(x + 4.5)ln(0.89) = ln(11(4)/(7))$
$((x + 4.5)ln(0.89))/(ln(0.89)) = (ln(11(4)/(7)))/(ln(0.89))$
$x + 4.5 = -2101.14032500$
$x = 2105.64032500$

Answers

The log expression log(z⁴/5) can be written in expanded form as 4log z - log 5 option (A) is correct.

What is a logarithm?

It is another way to represent the power of numbers, and we say that 'b' is the logarithm of 'c' with base 'a' if and only if 'a' to the power 'b' equals 'c'.

$\rm a^b = c\nlog_ac =b$

It is given that:

The log expression is:

= log(z⁴/5)

As we know, from the logarithm properties:

log mⁿ = n log m

log(m/n) = log m - log n

Applying log properties we get:

= log(z⁴/5)

= log z⁴ - log 5

= 4log z - log 5

Thus, the log expression log(z⁴/5) can be written in expanded form as 4log z - log 5 option (A) is correct.
