Answer: 1.1

Explanation:
7x = 7.7
you divide by 7 on both sides to isolate x.
7x/7 = 7.7/7
Therefore,
x = 1.1

Answer:

The value of x in the equation is 1.1

Step-by-step explanation:

7x = 7.7

Divide 7 on both sides of the equation.

x = 1.1

Determine the slope and y-intercept of the linear equation 2x - y = 4
Paul [167]
Get to y=mx+b form
m=slope
b=yint

2x-y=4
minus 2x from both sides
-y=-2x+4
times -1
y=2x-4
slope=2
yint=-4

equation of horizontal line is y=value

slope=rise/run, so rise is 0 and run is inifnity so 0 is slope

ycoordinate oof every point of a horizontal ine is the value above mentioned (value)


equation of vertical line is x=value

slope is rise/run, since run=0, it is infinity/0 which is undefined, slope=undefined

xcoordinate is equalt to the value (x=value)

general form of the equation of a line is y=mx+b or ax+by=c
every line has an equation that can be writeen in slope-intercept form

the line may not visually appear to have the slope indecated because somethimes the tick marks are not equal distance (use square viewer)




Determine the slope and y-intercept of the linear equation 2x - y = 4
2

The equation of a horizontal line is y=value. The slope of a horizontal line is 0. The y-coordinate of every point on the graph of a horizontal line is value (the one from y=value). The equation of a vertical line is x=value. The slope of a vertical line is undefined. The x-coordinate of every point on the graph or vertical line is value (x=value). The general form of the equation of a line is ax+by=c. Every line has an equation that can be written in slope-intercept form. When a graphing utility is used to sketch a straight line, the graph of the line may not visually appear to have the slope indicated by its equation because  the tick marks are not equally spaced

Write the equation of a line that is parallel to y=0.6x + 3 and that passes through the point (-3,-5)
Mkey [24]

Answer:

\large\boxed{y=0.6x-3.2}

Step-by-step explanation:

The slope-intercept form:

y=mx+b

m - slope

b - y-intercept

We have

y=0.6x+3

Parallel lines have the same slope. Therefore we have the equation:

y=0.6x+b

The line passes through the point (-3, -5). Put the coordinates of the point to the equation and solve it for b:

-5=0.6(-3)+b

-5=-1.8+b            <em>add 1.8 to both sides</em>

-3.2=b

Finally we have:

y=0.6x-3.2

An identification code is to consist of 3 letters followed by 2 digits. Determine the following
kirill [66]
Well let's see:

The first letter can be any one of 26 .
       For each one . . .
The second letter can be any one of the remaining 25.
       For each one . . .
The third letter can be any one of the remaining 24.
       For each one . . .
The two digits can be any number from 01 to 98 ...
       except 11, 22, 33, 44, 55, 66, 77, or 88.  (No repetition.)
      There are 90 of them.

So the total number of possibilities is    (26 · 25 · 24 · 90) .

When I multiply that out, I get   1,404,000 .

I don't know how you got your number, so I can't comment on your
method, but I did find something interesting about your number:

If I assume that you did the three letters the same way I did, then
if I divide your number by  (26·25·24), the quotient will show me
how you handled the two digits.

                         1,263,600 / (26·25·24)  =  81 .

That's very intriguing, because it's so close to the 90 sets of digits
that I used.  But I don't know what it means, or if it means anything
at all.
