Graph the line for y+1=−3/5(x−4) on the coordinate plane

1 answer:

7 0

Solve for y:
y + 1 = -3/5x + 2.4 (multiply 4 by 3/5 no negatives because negative times a negative is a positive)
y = -3/5x + 1.4
Now graph the y-intercept of 1.4.
Then plot points using slope.
Hope this helps and let me know if you have more questions!

Answer:

First picture - 20.42 m

Second picture - 12.9 m

Step-by-step explanation:

------------------------------------------------------------------------------------------------------------

Formula for pyramid:

$V=b^2\frac{h}3$

Where,

b = base - 3.5 m

h = height - 5 m

Thus,

$V=3.5^2\frac{5}{3}$

$20.41667m^3$ ≈ $20.42m^3$

------------------------------------------------------------------------------------------------------------

Formula for pyramid:

$V=b^2\frac{h}3$

Where,

b = base - 3 m

h = height - 4.3 m

Thus,

$V = 3^2\frac{4.3}{3}$

$12.9m^3$

A bacteria colony doubles in 8 hours. How long does it take to triple? Use N=No2^t/T

Volgvan

You will first find the unit rate which is single in four hours so then multiply by triple which is 3 and then you get triple will be in 12 hours

How many 5-digit numbers can be formed using the digits 0, 1, 2, 3, 4, 5, 6, if repetition of digits is not allowed? a.119 b.16,

Sergeeva-Olga [200]

Answer:
c. 2520

Explanation:
Repetition is not allowed, therefore:
1st digit can be any of the given 7 numbers
2nd digit can be any of the remaining 6 numbers
3rd digit can be any of the remaining 5 numbers
4th digit can be any of the remaining 4 numbers
5th digit can be any of the remaining 3 numbers
This means that:
number of possible combinations = 7 * 6 * 5 * 4 * 3 = 2520 numbers

Hope this helps :)
