find the holes
[tex]f(x)=\frac{x+3}{(x+1)(x-2)}[/tex]
Answer:
x=-1 and x=2Step-by-step explanation:
The "holes" are the x-es where function doesn't exist.
one must not divide by 0, so given function doesn't exis if the denominator is equal 0
The product {(x+1)×(x-2)} is equal 0 if any of factors {(x+1),(x-2)} is 0, so
x + 1 = 0 or x - 2 = 0
x = - 1 or x = 2
z varies directly with q. when z=2,q=1 .
find a formula connecting z and q
z=???
Answer:
[tex]z = \frac{q}{2} [/tex]
Step-by-step explanation:
[tex]z \infty q[/tex]
[tex]z = kq[/tex]
[tex]z = 2 \: and \: q = 1[/tex]
[tex]2 = k1[/tex]
[tex]k = \frac{2}{1} [/tex]
[tex]z = \frac{1}{2} q[/tex]
[tex]z = \frac{q}{2} [/tex]
9514 1404 393
Answer:
z = 2q
Step-by-step explanation:
The formula for direct variation is ...
z = kq . . . . . k is the constant of proportionality
We can find k using the given values of z and q:
k = z/q = 2/1 = 2
Then the equation connecting z and q is ...
z = 2q
wayne's country has a sales tax rate of 5%. How much does mike's car cost before tax if the total cost of the car plus tax is 13,032.60?
A percentage is a way to describe a part of a whole. The cost of the car is $12,412.
What are Percentages?A percentage is a way to describe a part of a whole. such as the fraction ¼ can be described as 0.25 which is equal to 25%.
To convert a fraction to a percentage, convert the fraction to decimal form and then multiply by 100 with the '%' symbol.
Given that Wayne's country has a sales tax rate of 5%. The total cost of the car plus tax is $13,032.60. Therefore, the total cost of the car can be written as,
The total cost of the car = Cost of the car + Tax on the car
$13,032.60 = Cost of the car + 5% of the cost of the car
Let the cost of the car be represented by x.
$13,032.60 = x + 5% of the x
$13,032.60 = x + 0.05
$13,032.60 = 1.05x
x = $13,032.60 / 1.05
x = $12,412
Hence, the cost of the car is $12,412.

Step-by-step explanation:
The four angles of a Parallelogram equal to 360. Its name is derived from the fact that its made up of two sets of parallel lines which means that its opposite angles are equivalent. Fortunately, you are given the values for the angles that are not equivalent which means you can create an equation and solve for x.
5x - 23 + 5x - 23 + 2x + 2x = 360
14x - 46 = 360
14x = 406
x = 29

Gavin is saving up to buy a new phone.
He already has $100 and can save an additional $7 per week using money from his after-school job
Let us assume that he worked for 'w' weeks
The amount earned for 'w' weeks = 100 + 7w
Hence, the required expression is 100 + 7w
The total amount saved in 10 weeks = 100 + 7(10) = $ 170
Therefore,
The total money would Gavin have after 10 weeks of savings is $ 170 and the required expression is 100 + 7w
