Answer: x-int = 10 and y-int = -12

Explanation:

Find x intercept:

To find x intercept set y = 0

3x - 2.5(0) = 30

3x = 30
x = 10

Find y-int:
Set x = 0

3(0) - 2.5y = 30
-2.5y = 30
y = 30/-2.5
y = -12

Answer:

x=0.833....y+10 (its a repeating 3)

y=1.2x−12

Step-by-step explanation:

for x is:

Add 2.5y to both sides.

3x−2.5y+2.5y=30+2.5y

3x=2.5y+30

Divide both sides by 3

x=0.833333y+10

for y is:

Add -3x to both sides.

3x−2.5y+−3x=30+−3x

−2.5y=−3x+30

Divide both sides by -2.5.

y=1.2x−12

hope this helps

Answer:

a) cluster sampling

Step-by-step explanation:

In cluster sampling method, each member of a population is assigned to one and only one group.This means clusters are formed through probability method usually a simple random sampling.The participants in the clusters are the only one to be surveyed.

In this example, simple random sampling is used to identify 12 home rooms(cluster) where a group of 20 students (participants) in each room is given the survey.

Which expressions are polynomials?

cupoosta [38]

The expressions that are polynomial are:

6 + w

$2x^4 - y$

z + 1

Solution:

A polynomial is an expression with variables and coefficients with the operations of addition, subtraction, multiplication, and non-negative integer exponents of variables

1) 6 + w

Here "w" is a variable, hence it is a polynomial expression

$2)\ 2x^4 - y$
