Answer:

A=B

Hence A+81=C

Now let's rearrange:

3A=99

So A= 33

B=33

and C = 33+81= 114

Solve 25^2x+1 = 144
Sergeu [11.5K]

Answer:

X = 0.272

Step-by-step explanation:

Firstly, use a common log on the 25 to undo it. Secondly, use the log25(144) on the other side to get ~ 0.54. Move the 1 over with subtraction and then divide out the 2. This will leave you with X= 0.272

Find the equation of a line, in slope-intercept fotm of a line that passes through the point (9,2) and is perpendicular to the l
cricket20 [7]

Considering the definition of perpendicular line, the equation of of perpendicular line is y= -\frac{1}{2}x + \frac{13}{2}.

<h3>Linear equation</h3>

A linear equation o line can be expressed in the form y = mx + b.

where

x and y are coordinates of a point.

m is the slope.

b is the ordinate to the origin and represents the coordinate of the point where the line crosses the y axis.

<h3>Perpendicular line</h3>

Perpendicular lines are lines that intersect at right angles or 90° angles. If you multiply the slopes of two perpendicular lines, you get –1.

<h3>Equation of perpendicular line in this case</h3>

In this case, the line is 2x-y=8. Expressed in the form y = mx + b, you get:

-y=8 - 2x

y= (-2x +8)÷ (-1)

y= 2x -8

If you multiply the slopes of two perpendicular lines, you get –1. In this case, the line has a slope of 2. So:

2× slope perpendicular line= -1

slope perpendicular line= (-1)÷ (2)

<u><em>slope perpendicular line= -</em></u>\frac{1}{2}

So, the perpendicular line has a form of: y= -\frac{1}{2}x + b

The line passes through the point (9, 2). Replacing in the expression for perpendicular line:

2= (-\frac{1}{2})× 9 + b

2=  -\frac{9}{2} + b

2+ \frac{9}{2}= b

<u><em /></u>\frac{13}{2}<u><em>= b</em></u>

Finally, the equation of of perpendicular line is y= -\frac{1}{2}x + \frac{13}{2}.
