Answer:

7/45

Step-by-step explanation:

First of all simplify

That becomes

-5+25x - 8x -2= -4x -8x

Then bring together values with similarities

-5 -2 = -4x -8x -25x +8x

-7 = -45x

x = 7/45

Write the formula for absolute value function if its graph has the vertex at point (0,6) and passes through the point (−1,−2).
valentinak56 [21]

First you need to find the slope of the line:

m =   \frac{y_2 - y_1}{x_2 - x_1}

m=6-(-2) / (-1)-0 =-8

equation of line is:

y=mx+b

y=-8x+6

for absolute value function:

if x<0

y=-8x+6

if x>0

y=+8x-6

The commission for selling a house is$11825, which is 5.5% of the selling price. What is the selling price of the house?
Rzqust [24]
In this case, the best method starts with finding one percent of the selling price.  To do this, divide the commission ($11825) by 5.5.  This gets you 1%, which is $2150.  Next, multiply this number by 100, turning 1% into 100%.  Your final answer is $215,000.

7.211; Starting from the left to right, x1=3 x2=7, y1=2 y2=8. Plug these in to the distance formula \sqrt{(x2-x1)^2+(y2-y1)^2

(7-3)^2+(8-2)^2

(4)^2+(6)^2

16+36

sqrt 52

Is x+3=-5y in standard form?
skad [1K]

Answer:

Nope

Step-by-step explanation:

Standard form for a linear equation in two variables is Ax+By=C with the terms containing  x  and  y  on the left side of the equation and a number on the right side.

x+3=-5y

Subtract 3 from both sides.

x=-5y-3

Add 5y.

x+5y=-3
