Answer:
a) pentagon
b) concave
c) not regular
Step-by-step explanation:
a) this polygon has 5 sides, known as a pentagon
b) it is concave because you can connect the top two vertices with a diagonal which will be outside the shape
c) a regular polygon is equilateral (all sides equal) but the markings show that is not the case with this shape
Does anyone know how to do simple interest for 7th grade math? I need a tutorial or an example please, thanks. A question example is $750, 7%, 3 years.
Answer:
750/100 X 7 = 52.50
52.50 X 3 = $157.50
Step-by-step explanation:
divide principal amount by 100 then multiply by interest percentage. this gave 52.50
now multiply the interest amount by number of years
in this case 3
52.50 X 3 = $157.50
Me.Lee ordered some pizzas to be delivered. The bill for the pizza was m dollars. Mr. Lee tipped the pizza delivery driver 15% of the bill. Write an expression for the total amount of money Mr. Lee paid
The expression would be: m + 0.15m and to know how much she paid I believe it would be 26.09 (rounded)

12z−6+15z=27z−5 how many solutions
Answer:
no solutions
Step-by-step explanation:
if you simplify the left side you will get 27z - 6 and the other side is 27z - 5
no value for 'z' will ever get these two expressions to equal each other because 6≠5

Monday Bellwork Which solution would make this equation have infinitely many solutions? 6(x – 3) + x = 7x +
-18, -9, 18, or 9
Answer:-18
Step-by-step explanation:
6(x−3)+x=7x−18
Step 1: Simplify both sides of the equation.
6(x−3)+x=7x−18
(6)(x)+(6)(−3)+x=7x+−18(Distribute)
6x+−18+x=7x+−18
(6x+x)+(−18)=7x−18(Combine Like Terms)
7x+−18=7x−18
7x−18=7x−18
Step 2: Subtract 7x from both sides.
7x−18−7x=7x−18−7x
−18=−18
Step 3: Add 18 to both sides.
−18+18=−18+18

-20t>-80 what is t and how do you graph it on a nuberline
Answer:
Step-by-step explanation:
Divide both sides by -20. If you divide by a negative, you have to switch the inequality sign. So now you have this for t:
t < 4
Draw a circle around 4 on a number line, but do not shade it in. Then everything below 4 is the right answer for the value of t.

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.

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
what is 64 thousandths in decimal form
The answer is .00064, because if you were to make in Thousand form it would look like this ➡️ 64,000. See the 3 Zeros? that is what makes it a thousand. now wht woul happen if we switched that around? well it would look like this ➡️ .00064. as you can see, there are 3 zeros, like in the last example. so your answer is ''.00064''

what is this 2x-5+22=?
Answer: 2x+17
Step-by-step explanation: add -5 and 22
______________________________
1.) Add −5 and 22:[tex]-5+22=17[/tex]
- You could also solve this by flipping the numbers around and subtracting 22 - 5, Which still gives you 17.
So your answer is [tex]\bold{(2x+17)}[/tex].

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.
