Input 0 for x, because the y-intercept is on the y-axis.

G(0) = 3(0) - 2

Simplify.

G(0) = -2

The answer is A, (0, -2)

Express (2-I) - (-1+3i) in the form of a + ib.

oksian1 [2.3K]

Answer:

$=3-4i$

Step-by-step explanation:

So we have:

$(2-i)-(-1+3i)$

First, distribute:

$=(2-i)+1-3i$

Combine like terms:

$=-i-3i+2+1$

Add:

$=-4i+3$

So, in the a+bi format, we will have:

$=3-4i$

In the contiguous United States, the ratio of states that border an ocean to states that do not border an ocean is 7:9. How many

Luda [366]

Answer:

Step-by-step explanation:

The contiguous U.S. consist of all states beside Alaska and Hawaii; therefore, there are 48 contiguous U.S. states. However, the ratio given to us only consists of 16 states [7 + 9 = 16]. If we need to expand the ratio, we multiply 16 by 3 to get 48. Thus, we also multiply each of the terms by 3, and the ratio becomes 21:27. Therefore, the number of contiguous U.S. states that border an ocean is 21.

What are the steps to answer -3(2r+7)=3

kumpel [21]

-3(2r+7)=3
distribute -3
-6r-21=3
add 21 to both sides, this causes the 21 on the left to cancel itself out.
-6r=24
divide each side by -6, this causes the -6 on the left side to cancel itself out.
r=-4

The average of four different positive integers is 9. What is the greatest value for one of the integers?

saul85 [17]

From the given information; Let the unknown different positive integers be (a, b, c and d).

An integer is a set of element that are infinite and numeric in nature, these numbers do not contain fractions.

Suppose we make an assumption that (a) should be the greatest value of this integer.

Then, the other three positive integers (b, c and d) can be 1, 2 and 3 respectively in order to make (a) the greatest value of the integer.

Therefore, the average of this integers = 9

Mathematically;

$\mathbf{\dfrac{(a+b+c+d)}{4} =9}$

$\mathbf{\dfrac{(a+1+2+3)}{4} =9}$

$\mathbf{\dfrac{(6+a)}{4} =9}$

By cross multiplying;

6+a = 9 × 4

6+a = 36

a = 36 - 6

a = 30

Therefore, we can conclude that from the average of four positive integers which is equal to 9, the greatest value for one of the selected integers is equal to 30.
