write in slope intercept form an equation of the line that passes through the points (-15, -1) and (10,4)
k0ka [10]
Find the slope first
m=y2-y1/x2-x1
m=4+1/10+15
m=5/25 = 1/5
use point slope formula and plug in any points
y-y1=m(x-x1)
y-4=1/5(x-10)
y-4=1/5x-2
y=1/5x+2

Please help<br><br><br><br><br>solve the following:<br>6(x-6)-5(x-7)=x+6​
Digiron [165]

Answer:

no \: solution

Step-by-step explanation:

1) Expand

6x - 36 - 5x + 35 = x + 6

2) Simplify 6x - 36 - 5x + 35 to x - 1.

x - 1 = x + 6

3) Cancle x on both sides.

- 1 = 6

4) Since −1 = 6 is false, there is no solution.

No Solution

Hence, this equation have no solution.

How do you make this equation 13+5y=6x into slope-intercept form?
Reil [10]
In slope-intercept form, the y variable is isolated.
so,
<span>13+5y=6x
Subtract 13 on both sides.
5y=6x-13
Divide by 5 on both sides.
y=6/5 x -13/5</span>

Anne wants to fill 12 hanging baskets with compost. Each hanging basket is a hemisphere of diameter 40 cm.
murzikaleks [220]

Answer:

no

Step-by-step explanation:

Steps to answering this question

  1. determine the volume of the 12 basket

volume of a hemisphere = (2/3)πr^3

n = 22/7

r = radius

the diameter is the straight line that passes through the centre of a circle and touches the two edges of the circle.

A radius is half of the diameter

radius = 40/2 = 20 cm

volume of one hemisphere = (2/3) x (22/7) x (20^3) = 16,761.90 cm^3

volume of the 12 baskets = 16,761.90 cm^3 x 12 = 201,142.86 cm^

2. convert the litres of compost to cm and multiply by the total bags of compost

1 litre = 1000cm

1 bag of compost = 50 x 1000 = 50,000

4 bags of compost = 50,000 x 4 = 200,000 cm

3. compare which figure is higher. the figure gotten in step 1 or 2

201,142.86 cm^3 is greater than 200,000

there is no enough compost
