Change 2x-y=-4 into slope-intercept form with steps

Mathematics
1 answer:
Shtirlitz [24]2 years ago
7 0

Answer:

y=2x - 4

Step-by-step explanation:

slope intercept is y = mx+b, where m is slope and b is y intercept.

subtract 2x from both sides of the equation

-y = 4 - 2x

multiply each term in -y = 4 - 2x by -1

(-y) . -1 = 4 . -1 + (-2x) . -1

y= 4. -1 + (-2x) . -1

simplify

y= -4 + 2x

Reorder

y= 2x - 4

Answer:

$1407.15

Step-by-step explanation:

$1,770.00*0.25= $442.5

$1.770-$442.50 = $1327.5

$1327.50+$79.65 = $1407.15

The population of a city is growing at an average rate of 3% per year in 1990 the population was 45 000.
Nonamiya [84]
This is an exponential growth/decay problem...

F=Ir^t, F=final value, I=initial value, r=rate, t=time, in this case:

F=I(1.03)^t  and they just want to know when F=2I so

2=1.03^t  take natural log of both sides...

ln2=t*ln1.03

t=ln2/(ln1.03)

t≈23.45

So it will take approximately 23.45 years for the population to double..

1990+23.45=2013.45

So during the year of 2013 the population will have double from its 1990 level.

The slope of the line below is 2. Which of the following is the the point-slope form of the line?
Jobisdone [24]

Answer:  y + 1 = 2 (x -1)

Step-by-step explanation:

Point slope form is:

y - y1 = m (x - x1)

Point on the line is (1, -1) and slope is 2

m = 2

y1 = -1

x1 = 1

y - (-1) = 2 (x - 1) or y + 1 = 2 (x -1)

-52 times the difference between a number and 14 is equal to the number plus 3
xenn [34]
X=number looked for
we have this equation:
-52(x-14)=x+3
we solve this equation:
-52x+728=x+3
-52x-x=3-728
-53x=-725
x=-725/-53=725/53 ≈13,68

Solution: 725/53

To check:
the difference between 725/53 and 14=725/53  - 14=(725-742)/53=-17/53
-52 times the diference is= -52(-17/53)=884/53
The number plus 3=725/53 + 3=(725+159)/53=884/53
