5/4 is the slope

Count the rise over run and you will get the slope

Answer:

5/4

Step-by-step explanation:

We have two points so we can use the formula for slope

(-3,-2) (1,3)

m = (y2-y1)/(x2-x1)

= (3--2)/(1--3)

= (3+2)/(1+3)

=5/4

The slope is 5/4

What is the polynomial function of lowest degree with lead coefficient 1 and roots 1 and 1 + i?

astra-53 [7]

x³ - 3x² + 4x - 2

complex roots occur in conjugate pairs

1 + i is a root then so is 1 - i

the factors of the polynomial are therefore

f(x) = (x - 1 )(x - (1 + i))(x - (1 - i))

= (x - 1 )(x² - 2x + 2 ) ( expand factors and simplify )

= x³ - 3x² + 4x - 2

Evaluate the piece-defined function for the given of x by matching the domain values with the range values

Elenna [48]

Answer:

The correct answer is:

(1) d

(2) b

(3) a

(4) c

(5) e

Step-by-step explanation:

The given problem is incomplete. Find the attachment of the full question.

According to the question,

(1)

By putting x = -2, we get

$f(x)=(-2)^3-5$

$=-8-5$

$=-13$

(2)

By putting x = 0, we get

$f(x)=(0)^3-5$

$=0-5$

$=-5$

(3)

By putting x = 3, we get

$f(x)=8$

(4)

By putting x = 9, we get

$f(x)=(2)^{9-7}$

$=(2)^2$

$=4$

(5)

By putting x = 11, we get

$f(x)=(2)^{11-7}$

$=(2)^4$

$=16$

Perl made the following conjecture.

Travka [436]

Answer:

No, it's not a counterexample, because 48 is a multiple of 8

Step-by-step explanation:

I think like 4 x 3 + 8 x 2 = 28 is a counterexample, because 28 is not a multiple of 8.

Write and equation in point-slope form for the line that passes through the points (-1,4) And is perpendicular to the line Y=-2x

miv72 [106K]

since it is perpendicular line you have to change thing signs of the equation.

x y

(-1,4)

replace the (-1) with x and (4) with y

y=1/2x+b

4=1/2(-1)+b

4=-1/2+b

4+1/2=b

9/2=b

therefore, the perpendicular line is y=1/2x+9/2

13_,644=130,000

MrMuchimi

Answer:

The possible digits 0, 1, 2 , 3 or 4 .

Step-by-step explanation:

The possible digits that could go in the thousands place to make 13_,644 ≈ 130,000 this statement correct are: 0 1, 2,3 or 4.

<u>For example:</u> 132,644 may rounded off to 130,000

Round the number to the nearest thousand make the numbers whose last three digit through 644 into the next lower numbers that ends in 000.

Using number line for this possibility as shown in the below diagram:
