(hopefully I read this right)

-5 1/4 - (-7 1/2)

-5 1/4 - -7 1/2

-5 1/4 - -7 2/4

-21/4 - -30/4

-21/4 - -30/4 = 9/4 = 2 1/4

Hopefully I am correct!

What is the equation of a line (in slope-intercept form) with a slope of -1 and a y
crimeas [40]

Remember that the slope intercept formula is:

y = mx + b

m is the slope

b is the y-intercept

What we know:

slope: -1

y-intercept: 0.7

Therefore:

m = -1

b = 0.7

Plug the values of <em>m </em>and <em>b </em>in y = mx + b:

y = -1x + 0.7

OR

y = -x + 0.7

OR

y = 0.7 - x

^^^These are all written in slope intercept form but just in different ways

Hope this helped!

Can somebody help me with questions 27 and 28?
jek_recluse [69]

check the picture below.


27)

since those angles on the other side, are alternate interior angles, then ∡RST = 110°.

28)

for the same reason, those angles on the outside are alternate interior angles to 110° and 120°, and those angles outside are linear angles with the ones inside, recall linear angles add up to 180°.

therefore ∡RST = 130°.

volcano Loihi

Step-by-step explanation:

Distance between volcano top and sea level is the summit elevation :

Summit elevation of volcano kliauea = 1227 miles

Summit elevation of volcano Loihi = - 969 m

The summit closer to sea level is that whose absolute summit level elevation is smaller :

Absolute values :

volcano kliauea = 1227 m

volcano Loihi = |-969| = 969 m

969 < 1227

Hence, volcano Loihi is closer to sea level
