4 0

The rate of change of the linear function whose graph passes through points (-5, -2) and (-2, 6) is: 2.7.

<h3>What is the Rate of Change of a Linear Function?</h3>

The rate of change of a linear function is given as change in y over change in x.

Given the points:

(-5, -2) and (-2, 6)

Change in y = 6 -(-2) = 8 units

Change in x = -2 -(-5) = 3 units

Rate of change = 8/3 = 2.7.

Which pair of complex factors results in a real-number product?
Crank

we will proceed to solve each case to determine the solution of the problem

we know that

i^{2} =-1

<u>case A</u>. 15*(-15i)

15*(-15i)=-225i

<u>The result of case A is not a real number product</u>

<u>case B</u>. 3i*(1-3i)

3i*(1-3i)=3i*(1)-(3i)*(3i)\\=3i-9i^{2}\\=3i-9*(-1)\\=3i+9

<u>The result of case B is not a real number product</u>

<u>case C</u>. (8+20i)*(-8-20i)

(8+20i)*(-8-20i)=8*(-8)+8*(-20i)+20i*(-8)-20i*(20i)\\=-64-160i-160i-400i^{2}\\=-64-320i-400*(-1)\\=-64-320i+400\\=336-320i

<u>The result of case C is not a real number product</u>

<u>case D</u>. (4+7i)*(4-7i)

(4+7i)*(4-7i)=4^{2} -(7i)^{2}\\=16-49i^{2}\\=16-49*(-1)\\=65\\

<u>The result of case D is a real number product</u>

therefore

<u>the answer is the option</u>

(4+7i)*(4-7i)

krok68 [10]
Any two lines that cross  form 2 sets of equal acute angles and 2 sets of obtuse angles. One of each will add to 180o.
 
obtuse + acute = 180
obtuse = 145
145 + acute = 180 subtract 145 from both sides.
acute = 180 - 145
acute = 35

Leokris [45]

The quantity of unleaded gasoline I can buy given the price of the gasoline per gallon is  8 gallons.

<h3>How many gallons can I buy?</h3>

Division is the process of dividing a number into equal parts using another number. The sign used to denote division is ÷. Division is one of the basic mathematical operations.

Number of gallons I can buy = amount I have / cost per gallon

$0 / $1.239 = 8 gallons
