Answer:

See attached photo for graph

Step-by-step explanation:

Solve the equation for y... (that means get y by itself)

4y = -5x - 6 (subtract 5x from both sides)

y = -(5/4)x - 6/4 (divide both sides by 4)

y = -(5/4)x - 3/2 (simplify)

Now you can graph using slope-intercept method. The y-intercept is -3/2, and the slope is -5/4

PLEASE HELP ASAP AND THANKS Find x

baherus [9]

Answer:

The value of x is 2.

Step-by-step explanation:

First, you have to make the left side into 1 fraction by making the denorminator the same :

$\frac{x}{x - 2} + \frac{1}{5}$

$= \frac{5x}{5(x - 2)} + \frac{x - 2}{5(x - 2)}$

$= \frac{5x + x - 2}{5(x - 2)}$

$= \frac{6x - 2}{5(x - 2)}$

Then you have to do cross multiplication :

$\frac{6x - 2}{5(x - 2)} = \frac{2}{x - 2}$

$(6x - 2)(x - 2) = 5(2)(x - 2)$

$6 {x}^{2} - 12x - 2x + 4 = 10x - 20$

$6 {x}^{2} - 14x + 4 = 10x - 20$

$6 {x}^{2} - 14x + 4 - 10x + 20 = 0$

$6 {x}^{2} - 24x + 24 = 0$

$6( {x}^{2} - 4x + 4) = 0$

${x}^{2} - 4x + 4 = 0$

${x}^{2} - 2x - 2x + 4 = 0$

$x(x - 2) - 2(x - 2) = 0$

$(x - 2)(x - 2) = 0$

$x = 2$

the equation for the given table is y=50x+250 if laura spends $850 how many hoursdid she rent the scooter ?

lesya [120]

Well then, you do
850 = 50x + 250
-250 -250
600 = 50x
/50 /50
12 = x
or
x = 12

O is the midpoint of segment FG. FO=3x+17, OG=7x-15. <br><br><br> 98 points

AlladinOne [14]

O is the midpoint so both sides FO and OG need to equal each other.

3x + 17 = 7x - 15

Subtract 3x from both sides:

17 = 4x -15

Add 15 to both sides:

32 = 4x

Divide both sides by 4:

x = 32/4

X = 8

Now you have the value of X, solve for the lengths:

FO = 3x +17 = 3(8) +17 = 24 +17 = 41

OG = 7x -15 = 7(8) -15 = 56-15 = 41

Total length would be 41 + 41 = 82

If 100 cats kill 100 mice in 100 days, then 4 cats would kill 4 mice in how many days ?

Gemiola [76]

If 100 cats killed 100 mice in 100 days, you can say that each cat killed one mouse the day after the last cat. So, if four cats killed four mice, and we're going of off the same basis that each cat killed one mouse the day after the last cat, then the answer would be 4.

Solve for v: -10=-5/4v

vagabundo [1.1K]

Answer:

v = 8

Step-by-step explanation:

-10= -5/4v first multiply both sides of the equation by -4/5

-10(-4/5) = v this cancels out the right side.

multiply the left side.

so you are left with 40/5 = v

next, simplify you will get 8=v
