Please help me with this math problem if you can. You just say yes or no if it’s a square, rectangle, etc. and then give the reason why
Answer:
Square.
Step-by-step explanation:
a). Properties of a square → 1). All sides are equal in measure
2). All interior angles are equal and measure 90°
3). Diagonals are perpendicular and equal in
measure.
Therefore, by third property, its a square because diagonals are perpendicular and congruent.
What is the inverse of function f?
9514 1404 393
Answer:
C. f^-1(x) = (∛(x+1))/4
Step-by-step explanation:
The inverse function can be found by solving x = f(y) for y.

Answer:
(8, 0)
Step-by-step explanation:
TAKE NOTE: In a glide reflection, you always start w/ the second transformation.
STEP 1: (2, 7) affected by the reflectionRULE (in this case): (x, y) --> (y, x)
(2, 7) => (7, 2)
STEP 2: (7, 2) affected by the translationRULE: (x, y) --> (x + horizontal shift, y + vertical shift)
(7, 2) => (7+1, 2-2) or (8, 0)
You can check your answer by doing this the opposite way.

If you have a hypotenuse that measures 13 inches, what do the side lengths need to be to create a right
triangle?
13 inches and 1 inch
12 inches and 10 inchas
12 inches and 5 inches
6 inches and 5 inches
Answer:
12 and 5 inches since squaring them would equal 144+25, which is 169, and ✓169=13. the two legs have to equal the hypotenuse when combined to be a right triangle.

Answer: CB = 7. AC = 5.
Step-by-step explanation:
Well we know that A-B is 7. And this is a right triangle, so the CB will be the same length. So CB = 7.
Now AC.
You divide 45 degrees by 7. And you get five.
So AC = 5 and CB = 7.

AC= 7√6/2
CB=7√2/2

Taking the readings from the graph
x .... y0 .... 22 .... 64 .... 106 .... 14Rate of change for the given line is:
(6 - 2)/2 = 4/2 = 2y- intercept is 2Equation for the line is:
y = 2x + 2For the point (40, 76) we can verify with the equation:
40*2 + 2 = 82The point (40, 76) is close the line but the line doesn't pass through it.
Answer:
x | y
0 | 2
2 | 6
4 | 10
6 | 14
Equation of the line is
[tex] \frac{y - 2}{x - 0} = \frac{6 - 2}{2 - 0} \\ \frac{y - 2}{x} = \frac{4}{2} = 2 \\ y - 2 = 2x \\ y - 2x = 2\\ \boxed{y=2x+2}[/tex]
When x=40, y will be (2×40)+2 =82
So the point should pass through (40,82) and not (40,76).
the sum of two number is 45. if one of them is 27 find other in equation with process
Step-by-step explanation:
Hey there!
Given;
The sum of two numbers is 45.
One of them is 27.
Let next number is "x".
So, Add "x" and "27" and show it is equal to 45.
Or, x+27 = 45
Therefore, x+27 = 45 is the required equation.
Now, solving unknown number.
~ Take "27" to right side and subtract it.
x= 45 - 27
X= 18
Therefore, next number is (x) = 18.
Hope it helps...
ANSWER = 18
Step-by-step explanation:
the sum of two no. =45
one no.=27

Please help! Lauren is 16, and Cara is 14. Their grandad gives them $1200 to share in the ratio of their ages. How much money do they each get? Show your work, please!!
Answer:
Lauren will get $640 and Cara will get $560.
Step-by-step explanation:
Given that:
Age of Lauren = 16
Age of Cara = 14
Ratio = 16 : 14
Amount given by their grandad = $1200
Let,
x be the number of times.
16x + 14x = 1200
30x = 1200
Dividing both sides by 30
[tex]\frac{30x}{30}=\frac{1200}{30}\\x=40[/tex]
Share of Lauren = 16x = 16*40 = $640
Share of Cara = 14x = 14*40 = $560
Hence,
Lauren will get $640 and Cara will get $560.
Jennifer received a $25 gift certificate from a music store. She can use it to buy 2 CD’s and 5 cassettes or 1 CD and 15 cassettes. Find the cost of 1 CD and 1 cassette.
Please help A.S.A.P.
Answer:
CD = 10$
Cassette = 1$
Step-by-step explanation:
ok, time to use some variables
C = CD
S = Cassette
2c + 5s = 25$
1c + 15s = 25$
the second equation has 1 less CD and 10 more Cassettes, therefore 1c = 10s
Now we can calculate how many Cassettes we can buy
1c - 1c = 0c
15s + 10s = 25s
This means that 25s = 25$
therefore 1s = 1$
since we know that 10s = 1c, and 1s = 1$, then we can figure out how many dollars the CD is
1c = 10s = 10$
1c = 10$

HELP ASAP A furniture manufacturer must pay $16.91 to make a certain kind of chair, which it can sell for $55.75. If the manufacturer has starting overhead costs of $18,340, not including production costs, how many chairs must it sell to realize a profit of $24,850, to the nearest chair?
a. 1,112
b. 918
c. 775
d. 640
(10 points and brainliest if the answer is right)
Answer:
A. 1,112
Step-by-step explanation:
The manufacturer needs to sell approximately 1,112 chairs to realize a profit of $24,850.
Option A is the correct answer.
What is an expression?
An expression contains one or more terms with addition, subtraction, multiplication, and division.
We always combine the like terms in an expression when we simplify.
We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.
Example: so
1 + 3x + 4y = 7 is an expression.com
3 + 4 is an expression.
2 x 4 + 6 x 7 – 9 is an expression.
33 + 77 – 88 is an expression.
We have,
Let's start by finding the profit per chair:
So,
Profit per chair = Selling price - Production cost
= $55.75 - $16.91
= $38.84
Next, we need to determine how many chairs the manufacturer needs to sell to make a profit of $24,850:
Profit = Profit per chair x Number of chairs sold - Overhead costs
$24,850 = $38.84x - $18,340
$43,190 = $38.84x
x = 1,112.49
Rounding to the nearest whole number, the manufacturer needs to sell approximately 1,112 chairs to realize a profit of $24,850.
Therefore,
The manufacturer needs to sell approximately 1,112 chairs to realize a profit of $24,850.

Answer:
Subtracting a number is the same as adding the opposite of the number
Step-by-step explanation:
Subtracting a negative number from a negative number – a minus sign followed by a negative sign, turns the two signs into a plus sign. So, instead of subtracting a negative, you are adding a positive. Basically, - (-4) becomes +4, and then you add the numbers. For example, say we have the problem -2 - –4.

what is the slope (2,-9) (-2,9)
Answer:

Step-by-step explanation:
[tex]\bold{slope\, (m)=\dfrac{change\ in\ Y}{change\ in\ X}=\dfrac{y_2-y_1}{x_2-x_1}}[/tex]
(2, -9) ⇒ x₁ = 2, y₁ = -9
