Solve: a = 0 a = 8 no solution

Mathematics
1 answer:
Anni [7]3 years ago
3 0

Answer:

  1)  a = 0

Step-by-step explanation:

Taking logarithms base 2, we have ...

  -3a·log2(1/8) = 3a·log2(512)

  -3a(-3) = 3a(9)

  27a -9a = 0 . . . . . . . subtract 9a

  a = 0/18 = 0 . . . . . . divide by 18

The solution is a = 0.

Find the equation of the line containing the points (20,28) and (25,38).
inna [77]

The equation of the line containing the points (20,28) and (25,38) is

y = 2x ₋ 12.

Given the points are: (20,28) and (25,38)

First find the slope of the line passing through the given points.

we know that (x₁,y₁) and (x₂,y₂) is m = y₂ ₋ y₁/x₂ ₋ x₁

therefore the slope of line passing through the points  (20,28) and (25,38) is:

m = 38 ₋ 28/25 ₋ 20

m = 10/5

m = 2

Consequently, the line's slope is 2.

Find the y-intercept now by using the slope and one of the two points.

y = mx ₊ b

28 = 2(20) ₊ b

28 = 40 ₊ b

28 ₋ 40 = b

b = ₋12

Next, represent the equation in slope-intercept form as follows:

y = mx ₊ b

y = 2x ₋ 12

hence the equation of the line is y = 2x ₋ 12.

A function has y-intercept of -2 and a slope of -1. which equation below describes the function?
ozzi
The correct equation should look something like this:
y= -1x - 2

Consider the equation for a line:
y = mx + b,
Where ‘m’ is the slope
Where ‘b’ is the y-intercept.

From there you can plug in your known values for ‘m’ and ‘b’, and get the equation above. If you are still not convinced, I suggest you graph the function and observe its slope and y-intercept.

Hope this helps!
