Answer:
52 minutes
Step-by-step explanation:
it takes him 13 minutes to complete 5 so if he wants to do 20 problems do 20 divided by 5 (4) then do 13 times 4=52
Answer:
slope= -3
y-intercept= 6
Step-by-step explanation:
1. Approach
To solve this problem, one needs the slope and the y-intercept. First, one will solve for the slope, using the given points, then input it into the equation of a line in slope-intercept form. The one can solve for the y-intercept.
2.Solve for the slope
The formula to find the slope of a line is;

Where (m) is the variable used to represent the slope.
Use the first two given points, and solve;
(1, 3), (2, 0)
Substitute in,

Simplify;

3. Put equation into slope-intercept form
The equation of a line in slope-intercept form is;

Where (m) is the slope, and (b) is the y-intercept.
Since one solved for the slope, substitute that in, then substitute in another point, and solve for the parameter (b).

Substitute in point (3, -3)

Answer:
m = -5/2
Step-by-step explanation:
Solve for slope with the following equation:
<em>m </em>(slope) = (y₂ - y₁)/(x₂ - x₁)
Let:
(4 , -12) = (x₁ , y₁)
(-2 , 3) = (x₂ , y₂)
Plug in the corresponding numbers to the corresponding variables:
<em>m </em>= (3 - (-12))/(-2 - 4)
<em>m</em> = (3 + 12)/(-2 - 4)
<em>m </em>= (15)/(-6)
Simplify the slope:
<em>m</em> = -(15/6) = -5/2
-5/2 is your slope.
