Write the standard form of the line that passes through the given points. Include your work in your final answer. Type your answ

romanna [79]

Answer:

11x+y = -28

Step-by-step explanation:

We have two points so we can find the slope

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

= (-6-5)/ (-2--3)

= -11(-2+3)

= -11/1

The slope is -11

We can use point slope to make an equation

y-y1 = m (x-x1)

y-5 = -11(x--3)

y -5 = -11(x+3)

Distribute

y-5 = -11x-33

Add 5 to each side

y-5+5 = -11x-33+5

y = -11x-28

Add 11x to each side

11x+y = -11x+11x-28

11x+y = -28

This is the standard form of a line

Write using exponential notation?<br> 5.5.2.2.2.2

inna [77]

Answer:

$5 ^{2} \times 2^{4}$

Step-by-step explanation:

Multiplying 5 by itself is the same thing as raising it to the second power:

$5 \times 5 = {5}^{2} = 25$

We multiply 2 by itself two seperate times. That's the same thing as raising 2 to the second power to the second power or in simpler terms raising two to the fourth power:

$2 \times 2 \times 2 \times 2 = {({2}^{2})}^{2} = {2}^{4} = 16$

Since only multiplication is present, we can combine the two terms to get:

$5^{2} \times {2}^{4}$
