Solve for the value of d.
(40+7)
(5d-3)°
HELP PLEASE
Answer:
d = 10 degrees
Step-by-step explanation:
You need to set the two equations equal to each other to solve this question:
(40 + 7) = (5d - 3)
(47) = (5d - 3)
47 = 5d - 3
50 = 5d
10 = d
d = 10 degrees
Triangle XYZ is rotated to create the image triangle X'Y'Z'.
On a coordinate plane, 2 triangles are shown. The first triangle has points X (negative 2, 2), Y (1, 2), Z (0, 4). The second triangle has points X prime (2, negative 2), Y prime (negative 1, negative 1), Z prime (0, negative 4).
Which rules could describe the rotation? Select two options.
R0, 90°
R0, 180°
R0, 270°
(x, y) → (–y, x)
(x, y) → (–x, –y)
Answer:
The correct option is;
R0, 180°
Step-by-step explanation:
The coordinates of ΔXYZ are given as follows;
X(-2, 2), Y(1, 2), Z(0, 4)
The coordinates of ΔX'Y'Z' are given as follows;
X'(2, -2), Y'(-1, -1), Z'(0, -4)
Whereby, the coordinates of the point Y' is (-1, -2), we have the rule that describe the transformation of ΔXYZ to ΔX'Y'Z', given as follows
Coordinates of the preimage = (x, y)
Coordinates of the image = (-x, -y)
Which is in accordance with the transformation by rotation 180° about the origin.

A business breaks even when the production costs are equal to the revenue. The expression 120 + 4x represents the cost of producing z items. The selling price is $5 for each item. Write an expression for the revenue generated by selling x items. How many items would you need to sell to break even? Write an equation and solve it. Enter the coIrect answers in the boxes. Hint Expression for revenue: Equation: Items needed to sell to break
Step-by-step explanation:
We know that revenue= production=break even point
given that the expression for cost of production is
z=120+4x---------------1 cost of production
where x is the number of items produced
also the selling price per item is $5
The revenue generated from the production of x items is(let the revenue be y)
y=5x------------2 revenue equation
break-even is when y=z
120+4x=5x
solving for x we have
120=5x-4x
120=x
x=120items

Answer:
She has 18 nickels and 36-18= 18 dimesSolving steps:
Question: jasmine has all nickels x and dimes y in her coin jar. if she has 36 coins in all, and four more dimes than. nickels find how much money she has in her coin jar
Find: how much money she has in her coin jar
Solution: let's make an equation for this problem
She has 4 more dimes than nikels:y= x+4 Let's use this value for y in the next equation:
x+x+4= 362x= 36x= 18
she has 18 nickels and 36-18= 18 dimes
The required Jasmine has 16 nickles and 20 dimes which constitute $2.80 in her coin jar.
Let's use the given information to set up a system of equations to solve for the number of nickels (x) and dimes (y) in Jasmine's coin jar.
We are given that Jasmine has a total of 36 coins in her jar, so we have the equation:
x + y = 36 -- Equation 1
We are also given that Jasmine has four more dimes than nickels, which can be expressed as:
y = x + 4 -- Equation 2
Now, let's solve this system of equations. We can substitute Equation 2 into Equation 1 to eliminate y:
x + (x + 4) = 36
2x = 36 - 4
x = 16
Now that we have the value of x, we can substitute it back into Equation 2 to find y:
y = x + 4
y = 16 + 4
y = 20
Therefore, Jasmine has 16 nickels (x) and 20 dimes (y) in her coin jar.
To find the total amount of money she has, we need to calculate the value of the nickels and dimes separately:
Value of nickels = 0.05 * 16 = $0.80
Value of dimes = 0.10 * 20 = $2.00
The total amount of money in her coin jar is:
$0.80 + $2.00 = $2.80
Jasmine has $2.80 in her coin jar.

x+4 over x^2-5x+6 ÷ x^2-16 over x+3
Answer:
x =± 4
Step-by-step explanation:
Solve for x:
x^2 - 16 = 0
The left hand side factors into a product with two terms:
(x - 4) (x + 4) = 0
Split into two equations:
x - 4 = 0 or x + 4 = 0
Add 4 to both sides:
x = 4 or x + 4 = 0
Subtract 4 from both sides:
Answer: x =± 4
Answer: (x + 3) / (x - 2)(x - 3)(x - 4)
Step-by-step explanation:
The problem given can be viewed as
a/b over c/d
where a/b is the top fraction and c/d is the bottom fraction.
This can be rearranged to
a × d / b × c
So, you will have:
(x + 4)(x + 3) / (x² - 5x + 6)(x² - 16)
Now, factor the two bottom polynomials so you end up with:
(x + 4)(x + 3) / (x - 2)(x - 3)(x + 4)(x - 4)
Cancel the (x + 4) on the top and bottom so you’re left with the answer:
(x + 3) / (x - 2)(x - 3)(x - 4)
If you need to find the solutions to x, set the denominator equal to zero.
x = 2
x = 3
x = 4

A set of numbers is given below.
{v/72 9.25, /83, pi 2 8.7}
Which list correctly orders the numbers from least to greatest
Answer:
Option (2)
Step-by-step explanation:
From the given set of numbers we have to arrange them in the increasing order.
{[tex]\sqrt{72},9.25,\sqrt{83},\pi^2,8.7[/tex]}
Since, [tex]\sqrt{72}=8.49[/tex]
[tex]\sqrt{83}=9.11[/tex]
[tex]\pi ^2[/tex] = 9.87
Therefore, set of numbers will be in the form of,
{8.49, 9.25, 9.11, 9.87, 8.7}
Now arranging these numbers in the increasing order,
8.49 < 8.7 < 9.11 < 9.25 < 9.87
Therefore, numbers in the increasing order will be,
{[tex]\sqrt{72},8.7,\sqrt{83},9.25,\pi ^{2}[/tex]}
