If f(x)= -2x+3 , find f(-1)?
Before we solve the equation let's take a look at it.
f(x) = -2x + 3
See how x appears in both f(x) and as the variable in the second half of the equation?
f(x) means "The function of x." You might also see g(x), h(x), and while those are the most common it can really be any letter, and any variable inside the parentheses.
So when we see f(-1), that means "The function of -1" or "The function of x when it is equal to -1."
Catching on? We need to replace x with -1 to solve for f(-1).
So here we go:
f(x) = -2x + 3
f(-1) = -2(-1) + 3
f(-1) = 2 + 3
f(-1) = 5
Voilà! We have solved for f(-1). Hope this helped.
Describe how each graph is obtained from the graph of y= f(x).
(a) y = f(x – 2)
Can somebody help telling what does it mean? what does it want us to do?
Answer:
see explanation
Step-by-step explanation:
Give the graph of y = f(x) then y = f(x + a) represents a horizontal translation of y = f(x)
• If x > 0 then a shift to the left of a units
• If x < 0 then a shift to the right of a units
Thus
y = f(x - 2) is the graph of y = f(x) translated 2 units right
A store selling art supplies finds that they can sell x sketch pads each week at a price of p dollars each, according to the formula x = 1000 − 400 p. What price should they charge (in interval notation and rounded to the nearest cent) if they want to sell
a . At least 625 pads each week? b . More than 300 pads each week?
c . Less than 200 pads each week? d . At most 475 pads each week?
Answer:
c and b and a
Step-by-step explanation:
The store should charge a price between ($0, $0.94] to sell at least 625 pads each week. The store should charge a price between ($0, $1.75) to sell more than 300 pads each week. The store should charge a price between ($2.00, $2.50) to sell less than 200 pads each week. The store should charge a price between [$1.31, $2.50) to sell at most 475 pads each week.
a)
In order to solve part a of the problem, we need to set our equation as an inequality. Part a asks us to find the price the store should charge to sell at least 625 pads each week. The word at least gives us a clue on what symbol to use. In this case we should use the [tex]\leq[/tex] symbol, like this:
[tex]625\leq 1000-400p[/tex]
and now we can solve the inequality, we can start by switching places between the 625 and the 400p so we get:
[tex]400p\leq 1000-625[/tex]
[tex]400p\leq 375[/tex]
and we divide both sides into 400, so we get:
[tex]p\leq \frac{375}{400}[/tex]
[tex]p\leq $0.94[/tex]
So this can be rewritten in interval notation like this:
($0, $0.94] The price they should charge can be located between those two values.
b)
In order to solve part b of the problem, we need to set our equation as an inequality. Part b asks us to find the price the store should charge to sell at more than 300 pads each week. The word more than gives us a clue on what symbol to use. In this case we should use the < symbol, like this:
[tex]300< 1000-400p[/tex]
and now we can solve the equation, we can start by switching places between the 300 and the 400p so we get:
[tex]400p< 1000-300[/tex]
[tex]400p< 700[/tex]
and we divide both sides into 400, so we get:
[tex]p< \frac{700}{400}[/tex]
[tex]p< $1.75[/tex]
So this can be rewritten in interval notation like this:
($0, $1.75) The price they should charge can be located between those two values.
c)
In order to solve part c of the problem, we need to set our equation as an inequality. Part c asks us to find the price the store should charge to sell less than 200 pads each week. The word less than gives us a clue on what symbol to use. In this case we should use the > symbol, like this:
[tex]200> 1000-400p[/tex]
and now we can solve the inequality, we can start by switching places between the 200 and the 400p so we get:
[tex]400p> 1000-200[/tex]
[tex]400p> 800[/tex]
and we divide both sides into 400, so we get:
[tex]p> \frac{800}{400}[/tex]
[tex]p> $2.00[/tex]
at this point we need to know what the maximum price the store can charge is. We can do so by setting the equation equal to zero and solve for p, so we get:
0<1000-400p
so we can now move the 400p to the other side of the equation, so we get:
400p<1000
and divide both sides into 400 so we get:
[tex]p<\frac{1000}{400}[/tex]
which simplifies to:
p<$2.50
if the store charges more than $2.50 they will not sell any item at all.
So this can be rewritten in interval notation like this:
($2.00, $2.50) The price they should charge can be located between those two values to sell less than 200 pads each week.
d)
In order to solve part d of the problem, we need to set our equation as an inequality. Part d asks us to find the price the store should charge to sell at most 475 pads each week. The word at most gives us a clue on what symbol to use. In this case we should use the [tex]\geq[/tex] symbol, like this:
[tex]475\geq 1000-400p[/tex]
and now we can solve the inequality, we can start by switching places between the 475 and the 400p so we get:
[tex]400p\geq 1000-475[/tex]
[tex]400p\geq 525[/tex]
and we divide both sides into 400, so we get:
[tex]p\geq \frac{525}{400}[/tex]
[tex]p\geq $1.31[/tex]
So this can be rewritten in interval notation like this:
[$1.31, $2.50) The price they should charge can be located between those two values to sell 475 pads at most each week.

It's 7.723, not 5.79.
If you get your bodmas correctly, you should get 7.723.
Solution:
Do "((-4.6) - 1.9) first, which is -6.5 basically.
After that it is (-2.78) x (-2.8), which is 7.784.
After that do (2.2 - 1.8) ÷ ((-4.6) - 1.9), which is -0.061
After that 7.784 + -0.061, which makes it 7.723.

what do you call a crushed angle ?
Answer:
A Rectangle
Step-by-step explanation:
a wrecked angle
A crushed angle is commonly referred to as a "rectangle" or a "wrecked angle".
When an angle is crushed or collapsed, its sides are no longer straight or evenly spaced, and its vertex may be shifted or deformed.
This deformation can occur in various contexts, such as in physical objects or in mathematical diagrams. The angle's original shape has been significantly changed due to external influences.
Thus, a crushed angle is commonly referred to as a "rectangle" or a "wrecked angle".
This is a play on words, as a rectangle is a shape with four right angles, and when an angle is crushed or wrecked, it can resemble a rectangle.
