Answer:

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c

Rearrange 3x - y = 4 into this form ( add y to both sides )

3x = y + 4 ( subtract 4 from both sides )

3x - 4 = y OR y = 3x - 4 → a

PLEASE HELP, BEEN STUCK FOR AN HOUR!!

pashok25 [27]

Answer: C.

Both functions are decreasing, but function f is decreasing at a faster average rate on that interval.

Step-by-step explanation:

Let first work out g(x)

When x = 0

g(x) = 75

When x = 1

g(x) = 75( 1 - 50%)

g(x) = 75(0.5) = 37.5

Which is less than 43

With this, we can conclude that:

Both functions are decreasing, but function f is decreasing at a faster average rate on that interval.

Answer:

The answer is B

Step-by-step explanation:

If u use calculator,u will get the ans as x¹=6 and x²= -2 but u have to change it to the opposite which means negatif to positive(-2=2) and positive to negative(6= -6).Hope u can understand...sorry,English isn't my first language

4x - 3y = 15<br> 2x + 2y = 4<br><br> what is the solution of the system of equations?

klio [65]

Answer:

System of Linear Equations entered :

[1] 4x - 3y = 15

[2] 2x + 2y = 4

Step-by-step explanation:

// Solve equation [2] for the variable y

[2] 2y = -2x + 4

[2] y = -x + 2

// Plug this in for variable y in equation [1]

[1] 4x - 3•(-x +2) = 15

[1] 7x = 21

// Solve equation [1] for the variable x

[1] 7x = 21

[1] x = 3

// By now we know this much :

x = 3

y = -x+2

// Use the x value to solve for y

y = -(3)+2 = -1

Solution :

{x,y} = {3,-1}

Records for the past several years show that 46% of customers at a local game shop use a customer loyalty card. Due to a recent

Ratling [72]

Answer:

1. Null hypotheses: p=0.49

Alternative hypotheses: p>0.49

2. p=0.5704 or 57.04%

Step-by-step explanation:

We have to writer the hypotheses for testing the proportion has increased from 49%. So, the population proportion that is to be tested is 0.49.

As we already know that the null hypotheses always contain equality so,

Null hypotheses: p=0.49

and we have to test whether the proportion has increased from 0.49, so,

Alternative hypotheses: p>0.49

Thus, the hypotheses for testing the proportion has increased from 49% are

Null hypotheses: p=0.49

Alternative hypotheses: p>0.49

We have to find the proportion of sampled customers using loyalty card.

The given sample indicate that 77 out of 135 customers are using loyalty card. So,

p=x/n

where x is the number of favorable outcome and n is total number of outcome.

Here, x=77 and n=135. So,

p=77/135=0.5704 or 57.04%
