Answer:
y = 
x - 7
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 = 
with (x₁, y₁ ) = (- 2, - 8) and (x₂, y₂ ) = (2, - 6)
m = 
= 
= , thus
y = x + c ← is the partial equation
To find c substitute either of the 2 points into the partial equation
Using (2, - 6), then
- 6 = 1 + c ⇒ c = - 6 - 1 = - 7
y = x - 7 ← equation of line
I put in the x coordinate for where y was 80 and the y coordinate for where x was 3. Then I subtracted them to get the slope. Hope this helps.
Answer:
4.6 and 3.5 and 3.6.
Step-by-step explanation:
Because they have to be in a range between 3.7 and 4.3.
Subtract four from both sides. That'll put both numbers without a variable on one side, and the number with the variable is by itself.
Answer:
7238 rounded to the nearest whole number.
Step-by-step explanation:
To find the volume of the sphere, we use the formula.
The radius will be 24 units ÷ 2 = 12 units.
Hence, the volume is
When entered in a calculator you'll get a result of 7238.23 cubic units in or 7238 rounded to the nearest whole number.
