HELPP!! I report wrong answers!!

Which phrase describes density? height of a point above sea level force pushing on an area or a surface amount of mass in a cert

Mrrafil [7]

A surface amount of mass in a certain volume amount of matter an object contains.

I believe the second sentence is the answer since density is the measurement that compares the amount of matter that an object has to its volume.

Show how to make a ten to solve 3 - 7

Marta_Voda [28]

The 3 is a positive integer and the 7 is a negative integer so you would do "KFC" also known as (Keep, Flip, and Change)

3
("Keep" the 3 positive)
-
("Flip"the minus sign into a plus sign)

-7
("Change" the negative sign into a positive sign)

So therefore, you would have:

3 + 7, which equals 10

What is the slope-intercept form of the equation of the line that passes through the points (−3, 2) and (1, 5) ?

madam [21]

Answer:

C

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Calculate m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (- 3, 2) and (x₂, y₂ ) = (1, 5)
