If m∠BDC=(8x+12)° and m∠FDB=(12x−32)°, find m∠FDE.
The measure of angle FDE (m ∠FDE) is m ∠FDE = 92°
Measure of anglesFrom the question, we are to find the measure of angle FDE
In the given diagram, we can observe that
∠BDC + ∠FDB = 180° (Sum of angles on a line segment)
From the given information,
m ∠BDC = (8x+12)°
and
m ∠FDB = (12x−32)°,
Thus,
(8x+12)° + (12x−32)° = 180°
8x + 12 + 12x - 32 = 180
8x + 12x = 180 + 32 - 12
20x = 200
x = 200/20
x = 10
Now, we are to determine the measure of angle FDE (m ∠FDE)
In the diagram,
∠FDE = ∠BDC (Vertically opposite angles)
Thus,
m ∠FDE = (8x+12)°
Put the value of x into the equation
m ∠FDE = (8(10)+12)°
m ∠FDE = (80+12)°
m ∠FDE = 92°
Hence, the measure of angle FDE (m ∠FDE) is m ∠FDE = 92°
Here is the complete question:
Refer to the figure.
If m∠BDC=(8x+12)° and m∠FDB=(12x−32)°, find m∠FDE.

Sal's Sandwich Shop sells wraps and sandwiches as part of its lunch specials. The profit on every sandwich is $2 and the profit on every wrap is $3. Sal made a profit of $1,470 from lunch specials last month. The equation 2x + 3y = 1,470 represents Sal's profits last month, where x is the number of sandwich lunch specials sold and y is the number of wrap lunch specials sold.
1. Change the equation to slope-intercept form. Identify the slope and y-intercept of the equation. Be sure to show all your work.
2. Describe how you would graph this line using the slope-intercept method. Be sure to write using complete sentences.

A variable is a quantity that can change; the word also refers to the letter or symbol that represents this quantity. In a proportional relationship, one variable is the independent variable, and one is the dependent variable. They are often called “x” and “y,” but any letters can be used.The value of the dependent variable depends on the value of the independent variable. In the relationship between number of scoops of ice cream and total price, we can call number of scoops “x” and total price “y.” Y is dependent because its value depends on x, the number of scoops you purchase.Ursula makes $5 for every 1 dog she walks.

We are to express a given fraction into a decimal.
A fraction is the ratio of two numbers usually with a numerator and the denominator separated by a horizontal bar in between them.
On the contrary, the division of the fraction will result in a decimal number(a standard system of representing fractions)
To divide;
[tex]\mathbf{=\dfrac{15}{27}}[/tex]
= 0.5556
Therefore, we can conclude that the fraction 15/27 in decimal = 0.5556

no solution solution and infinitely many solutions?
Answer:
Step-by-step explanation:
56n+24 = 24 + 7n
49n + 24 = 24
49n = 0
n = 0
solution
Answer:
n = 0
Step-by-step explanation:
8(7n + 3) = 24 +7n
1. distribute the 8 inside the paranthesis
56n + 24 = 24 + 7n
2. subtract 24 from both sides
56n = 7n
3. subtract 7n from both sides
49n = 0
n = 0
Given the point A(-2,0)
If T<3,2> A = B, then B ia the point
Answer:
Point B is (1, 2)
Step-by-step explanation:
Let us revise the rule of the translations
If the point (x, y) translated horizontally to the right by h units then its image is (x + h, y) ⇒ T (x, y) → (x + h, y)If the point (x, y) translated horizontally to the left by h units then its image is (x - h, y) ⇒ T (x, y) → (x - h, y)If the point (x, y) translated vertically up by k units then its image is (x, y + k)→ (x + h, y) ⇒ T (x, y) → (x, y + k)If the point (x, y) translated vertically down by k units then its image is (x, y - k) ⇒ T (x, y) → (x, y - k)∵ Point A = (-2, 0)
∵ T (3, 2) → A = B
→ By using the 1st and 3rd rules above, A is translated 3 units right and 2
units up to get B
∴ T (x, y) → (x + 3, y + 2)
∵ A = (x, y)
∵ x = -2 and y = 0
∴ B = (-2 + 3, 0 + 2)
∴ B = (1, 2)
∴ Point B is (1, 2)

Let y= 2t + 5 be a linear function representing the distance, in feet, from home for an ant t minutes after starting out from a location near its home. What does the number 2 represent in this function?
Answer:
2 represents the slope
Step-by-step explanation:
Given the linear function representing the distance, in feet, from home for an ant t minutes after starting out from a location near its home expressed as
y = 2t + 5. This function is a linear function of the form y = mx+c where;
m is the slope (change in y with respect to x)
c is the intercept
Comparing this standard equation to y = 2t + 5, we will see that 2 represents the slope m which is change in the distance covered in feet with respect to the time taken

A rectangular solid has width w, a length of 7 more than the width, and a height that is equivalent to 15 decreased by 3 times the width. Express the volume in terms of the width. Then find the maximum volume
Answer:
For a rectangular solid with:
width = w
length = l
height = h
The volume is equal to:
V = w*l*h
in this case we know that:
width = w.
"length of 7 more than the width"
l = w + 7.
"a height that is equivalent to 15 decreased by 3 times the width."
h = 15 - 3*w
Then the volume will be:
V = w*l*h = w*(w + 7)*(15 - 3w) = (w^2 + 7*w)*(15 - 3*w)
V = ( -3*w^3 + 15*w^2 + 105*w - 21*w^2)
V = (-3*w^3 - 6*w^2 + 105*w)
Now, the maximum volume will be for the value of w such that:
V'(w) = 0.
and:
V''(W) < 0
Where:
dV/dw = V'(w).
dV'/dw = V''(w)
Then first we need to differentiate the equation for the volume.
V'(w) = dV/dw = ( 3*(-3*w^2) + 2*(-6*w) + 105)
V'(w) = -9*w^2 - 12*w + 105.
Then we need to find the solution for:
-9*w^2 - 12*w + 105 = 0.
We can use the Bhaskara formula, and we will get:
[tex]w = \frac{+12 +-\sqrt{(-12)^2 - 4*(-9)*105} }{2*-9} = \frac{+12 +- 62.6}{-18}[/tex]
Then the two solutions are:
w₁ = (+12 - 62.6)/(-18) = 2.81
w₂ = (+12 + 62.6)/(-18) = -15.5
But we can not have a negative width, so we can just discard the second solution.
Now let's check the second condition for the maximum, we must have:
V''(2.81) < 0.
V'' = dV'/dw = 2*(-9*w) - 12 = -18*w - 12
V''(2.81) = -18*2.81 - 12 = -62.58 < 0 .
Then the volume is maximized when w = 2.81, and the maximum volume will be:
V(2.81) = (-3*(2.81)^3 - 6*(2.81)^2 + 105*2.81) = 180.1
Find the value of x.
Answer:
The answer is X equals 17
