Can someone show me the work for the problem 6x-9y=-2i am trying to put the problem in slope-intercept form

1 answer:

6 0

Slope intercept form is y=mx+c
6x-9y=-2
Solve for y,
-9y = -6x -2
y = (6/9)x + (2/9)
y = (2/3)x +(2/9)
Hence, the slope intercept form of the equation is y=(2/3)x + (2/9)

Answer:

y = 8

Step-by-step explanation:

Line1 with points (4, 1) and (0, 0):

slope = (y₂ - y₁) / (x₂ - x₁)

= (0 - 1) / (0 - 4)

= 1/4

Perpendicular line is opposite inverse so original slope 1/4 becomes -4/1 or simply -4.

Line2 with points (1, 0) and (-1, y):

slope = (y₂ - y₁) / (x₂ - x₁)

= (y - 0) / (-1 - 1)

= y / -2

y must equal to 8 for the slope to be -4 as stated above.

carmen rides her bicycle at a constant rate to the market. when she rides her bicycle back home along the same route, she bikes

sergeinik [125]

The answer is 28.
Check: 28-12= 16
1/4 of 16= 4
3/4 of 16= 12
so Carmen takes 3/4 more time of the trip to the market when she return s home.

Chang is estimating the volume of his bathtub the actual volume of his bathtub is 37 gal chang’s estimate is 31 gal find the abs

stepladder [879]

<h3>The absolute error is 6</h3><h3>The percent error is 16.22 %</h3>

<em><u>Solution:</u></em>

Given that,

Actual volume of his bathtub is 37 gal

Estimate is 31 gal

<em><u>Find the absolute error</u></em>

Absolute Error = | Measured Value - Actual Value |

Absolute Error = | 31 - 37 |

Absolute Error = 6

<em><u>Find the percent error</u></em>

$Percent\ error = \frac{\text{estimate - actual}}{actual} \times 100$

Substituting we get,

$percent\ error = \frac{31-37}{37} \times 100\\\\percent\ error = \frac{-6}{37} \times 100\\\\percent\ error = -16.22$

Negative sign means percent decrease

Thus percent error is 16.22 %
