I need to find the slope and b Y=mx+b HELP ME

Naddika [18.5K]

Answer:

$y=-\frac{4}{3}x+20$

Step-by-step explanation:

stupid enough

y=mx+b

$\frac{y1-y2}{x1-x2}$

slope = 16-12/3-6

-4/3

$y=-\frac{4}{3}x+b$

plug in x and y

16=-4/3(3)+b

b=20

If there are approximately 1.8 million cars in Vancouver and if each car travels an average of 17,500 kilometres in a year, how

Goryan [66]

Rates are used to measure a quantity over another.

The 1.8 million cars use $1.85 \times 10^{10}$ liters each year

Given

$Cars = 1.8\ million$

$d = 17500km$ --- distance

$r = 40miles/gallon$

First, we calculate the number (n) of gallons used by each car

$r = \frac{d}{n}$

Solve for n

$n = \frac{d}{r}$

So, we have:

$n = \frac{17500km}{40miles/gallon}$

$n = \frac{17500km}{40miles}gallon$

Convert miles to kilometers

$n = \frac{17500km}{40km \times 1.60934}gallon$

$n = \frac{17500km}{64.3738km}gallon$

$n = 271.85\ gallon$

The number of gallons (N), used by all the cars is:

$N = n \times cars$

$N = 271.85 \times 1.8\ million$

$N = 489330000$

Convert to liters

$N = 489330000 \times 3.78541L$

$N = 1852314675.3L$

In scientific notation to 2 decimal places, we have:

$N = 1.85 \times 10^{10}L$

Hence, the number of liters used is $1.85 \times 10^{10}$

Find the dimensions of a rectangle with an area of 100 square feet that has the minimum perimeter.

STatiana [176]

The polygon with the shortest perimeter for a given area is a regular polygon. The regular 4-sided polygon is the square.

The side length of the square with an area of 100 ft² is √(100 ft²) = 10 ft.

The rectangle with the minimum perimeter for an area of 100 ft² is 10 ft by 10 ft.

A circle has the equation x^2+y^2+x-6y+9=0. Find the center and any x or y intercepts.

Softa [21]

We know:x^2+y^2+x−6y+9=0So, we complete the square as such:x^2+y^2+x−6y+9=x^2+x+y^2−6y+9=(x+1/2)^2+(y−3)^2=(1/2)^2=1/4

Can someone help me with this please

ryzh [129]

Answer:

y=4

Step-by-step explanation:

You can ignore the 3 and 6 because this has no y value change(rise over run)

This is a straight horizontal line so the equation is y=4.

Slope=0
