Answer:
3/4 x 12/1 because if you can decorate 3/4 a cupcake per minute, you multiply 3/4 by 12 to find the total amount of cupcakes he could decorate. 3/4 x 12/1 = 9 Paul can decorate 9 cupcakes in 12 minutes.

Answer: f(x) = x³ + x² - 26x + 24
<u>Step-by-step explanation:</u>
x = 4 x = -6 x = 1
x - 4 = 0 x + 6 = 0 x - 1 = 0
(x - 4) (x + 6) (x - 1) = 0
(x² + 2x - 24)(x - 1) = 0
x(x² + 2x - 24) -1(x² + 2x - 24) = 0
x³ + 2x² - 24x -x² - 2x + 24 = 0
x³ + x² - 26x + 24 = 0
Answer:
3x + 5y = 1
Step-by-step explanation:
the equation of a line in standard form is
Ax + By = C ( A is a positive integer and B, C are integers )
Obtain the equation in slope- intercept form
y = mx + c ( m is the slope and c the y-intercept )
to calculate m use the gradient formula
m = ( y₂ - y₁ ) / ( x₂ - x₁ )
with (x₁, y₁ ) = (- 3, 2) and (x₂, y₂ ) = (2, - 1) ← 2 points on the line
m =
= -
y = -
x + c ← is the partial equation
to find c substitute either of the 2 points into the partial equation
using (2, - 1), then
- 1 = -
+ c ⇒ c = - 1 +
= 
y = -
x +
← in slope-intercept form
multiply all terms by 5
5y = - 3x + 1 ( add 3x to both sides )
3x + 5y = 1 ← in standard form
The square root of 11 = 3.3166
which is between 3 and 4 so the first one is the answer
