3. Give the slope and y-intercept of the<br> relationship shown in the table.

kolezko [41]

Answer:

Step-by-step explanation:

Since the slope is going down the slope is negative and since 50 is positive when 0 its positive.

Also to find slope you do y/x

25/100=1/4 and since its a decreasing pattern the slope is -1/4

A right triangle has side lengths 7, 24, and 25 as shown below.

elixir [45]

Answer:

SinL = 7/25

CosL = 24/25

TanL = 7/24

Step-by-step explanation:

Find the diagram attached.

Using SOH CAH TOA in trigonometry identity to find the sinL, cosL and TanL

Note that the hypotenuse is the longest side = 25

The opposite will be the side facing the acute angle L

Opposite = 7

Adjacent = 24

For SinL

sinL = Opposite/Hypotenuse {SOH}

SinL = 7/25

For cosL:

CosL = Adjacent/Hypotenuse{CAH}

CosL = 24/25

For tanL:

TanL = Opposite/Adjacent {TOA}

TanL = 7/24

How do you subtract<br> -6 - (-7)? <br> Can you explain it step by step too? Thanks!

djverab [1.8K]

$\bf -6-(-7)\implies -6-1(-7)\implies -6-1\cdot -7\implies -6+(-1\cdot -7)
\\\\\\
-6+(+7)\implies -6+7\implies 1$
