f÷−32=−31
whats the answer?
Reformatting the input :
Changes made to your input should not affect the solution:
(1): "/-32" was replaced by "/(-32)".
Rearrange:
Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :
f/(-32)-(-31)=0
Step by step solution :

Rewriting the whole as an Equivalent Fraction
2.1 Subtracting a whole from a fraction
Rewrite the whole as a fraction using -32 as the denominator :
-31 -31 • -32
-31 = ——— = —————————
1 -32
Equivalent fraction : The fraction thus generated looks different but has the same value as the whole
Common denominator : The equivalent fraction and the other fraction involved in the calculation share the same denominator
Adding fractions that have a common denominator :
2.2 Adding up the two equivalent fractions
Add the two equivalent fractions which now have a common denominator
Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:
f • -1 - (-31 • 32) 992 - f
——————————————————— = ———————
32 32
Equation at the end of step
2
:
992 - f
——————— = 0
32
STEP
3
:
When a fraction equals zero
3.1 When a fraction equals zero
Where a fraction equals zero, its numerator, the part which is above the fraction line, must equal zero.
Now,to get rid of the denominator, Tiger multiplys both sides of the equation by the denominator.
Here's how:
992-f
————— • 32 = 0 • 32
32
Now, on the left hand side, the 32 cancels out the denominator, while, on the right hand side, zero times anything is still zero.
The equation now takes the shape :
992-f = 0
Solving a Single Variable Equation:
3.2 Solve : -f+992 = 0
Subtract 992 from both sides of the equation :
-f = -992
Multiply both sides of the equation by (-1) :
f = 992
the answer is f = 992

(x - 1) is a factor of the following, what are the remaining 2 factors:
Answer:
(x +(-2) ) and ( x+3)
The factors of a given cubic polynomial function are
( x-1) (x -2 ) and (x +3)
Step-by-step explanation:
Step(i):-
Given that x³ - 7x + 6=0
f(x) = x³ - 7x + 6=0
put x=1
f(1) = 1 -7 +6 =0
(x -1 ) is one factor of given polynomial
By using synthetic division
x³ x² x constant
x=1 ║ 1 0 -7 6
║ 0 1 1 -6
1 1 -6 0
The polynomial ( x² + x - 6) =0
Step(ii):-
The factors of
x² + x - 6=0
x² + 3x -2x - 6=0
x ( x +3 ) - 2( x +3) =0
(x -2 ) ( x+3 ) =0
x = 2 and x =-3
Final answer:-
The factors of a given cubic polynomial function are
( x-1) (x -2 ) and (x +3)

Determine whether or not the following graph represents two quantities that are proportional to each other. Explain your reasoning.
Answer:
The quantities are not proportional.
Step-by-step explanation:
The values, x and y, do not begin or pass through the origin, (0,0). This means they are not proportional.
The graph represents two quantities are not proportional to each other.
What is Proportional?A relationship is proportional if each pair of data values are related in the same way, by multiplying by a factor. You can recognize a proportional relationship by looking at data, an equation, or a graph.
Given:
As, A relationship is proportionate if its graph is a line or ray that passes through the origin.
and, It is not proportionate if the line or ray does not go through the origin. Additionally, if anything is not linear, it is not proportional.
Here the graph also does not pass through the origin.
Hence, the graph is not proportional.

Figure ABCD is a parallelogram.
Parallelogram A B C D is shown. Angle B is (2 n + 15) degrees and angle D is (3 n minus 5) degrees.
What are the measures of angles B and D?
∠B = 55°; ∠D = 55°
∠B = 55°; ∠D = 125°
∠B = 97°; ∠D = 97°
∠B = 83°; ∠D = 97°
Answer:
A. ∠B = 55°; ∠D = 55°
Step-by-step explanation:
Hope this helps :)
The measures of angles B and D are (a) ∠B = 55°; ∠D = 55°
What is a parallelogram?A parallelogram is a shape whose opposite sides are parallel and congruent
The following is the step to determine the measures of angles B and D
We have:
B = 2n + 15
D = 3n - 5
The angles are opposite angles.
So, we have:
B = D
This gives
2n + 15 = 3n - 5
Collect like terms
3n - 2n = 15 + 5
n = 20
Substitute 20 for n in B = 2n + 15
B = 2 * 20 + 15
B = 55
Hence, the measures of angles B and D are (a) ∠B = 55°; ∠D = 55°

A large spherical structure has a 37.5-foot radius. The sphere is covered with panels. If each panel has an area of about 49 ft2, approximately how many panels would be needed to cover the entire sphere?
360
940
17,660
310,000
Answer:
Option (1)
Step-by-step explanation:
Radius of the spherical structure = 37.5 feet
Surface area of each panel = 49 square feet
Sphere is covered with panels.
Therefore, area of the panels needed = [tex]\frac{\text{Total surface area of the sphere}}{\text{Area of one panel}}[/tex]
Surface area of the sphere = 4πr²
Here 'r' = radius of the sphere
For a sphere having radius 'r' = 37.5 feet,
Surface area of the sphere = 4π(37.5)²
= 17671.5 feet²
Number of panels required to cover the sphere = [tex]\frac{17671.5}{49}[/tex]
= 360
Therefore, Option (1) will be the answer.

The function y = 5.45 + 1.05(x + 7) can be used to determine the cost in dollars for a prepaid cell phone plan of x minutes. What is the rate of change of the cost, in dollars, with respect to the number of minutes purchased?
Answer:
1.05
Step-by-step explanation:
The rate of change of the cost, in dollars, with respect to the number of minutes purchased is 1.05 and this can be determined by differentiating the given function.
Given :
Function -- y = 5.45 + 1.05(x + 7)'y' is the cost in dollars for a prepaid cell phone plan of 'x' minutes.In order to determine the rate of change of the cost, in dollars, with respect to the number of minutes purchased, differentiate the given function with respect to 'x'.
y = 5.45 + 1.05(x + 7)
y = 5.45 + 1.05x + 7.35
y = 12.8 + 1.05x
Now, differentiate the above equation with respect to 'x'.
[tex]\dfrac{dy}{dx} = 0 + 1.05[/tex]
So, the rate of change of the cost, in dollars, with respect to the number of minutes purchased is 1.05.

Step-by-step explanation:
When we solve for this we should always remember this formula [tex]a^2+b^2=c^2[/tex] and since we already know a and b we can plug that in to find out what c could be but we won't actually solve it.
[tex]a^2+b^2=c^2\\4^2+4^2=c^2\\16+16=c^2\\32=c^2\\\sqrt{c^2}=\sqrt{32}\\c=\sqrt{32}[/tex]
