Can anyone help? This is super difficult.
Answer:
A
Step-by-step explanation:
Recall that from the Exterior Angle Theorem, the exterior angle is equal to the sum of the two interior angles opposite from the exterior angle.
In other words:
[tex]\displaystyle m\angle QPT = m\angle HQP + m\angle PHQ[/tex]
We are given the expressions of each angle. Substitute:
[tex](6x+20)^\circ = (x+40)^\circ + (4x-5)^\circ[/tex]
Solve for x:
[tex]\displaystyle \begin{aligned} 6x + 20 & = (x+40) + (4x-5) \\ \\ 6x + 20 & = 5x + 35 \\ \\ x & = 15 \end{aligned}[/tex]
Hence, the value of x is 15.
Then the measure of ∠QPT will be:
[tex]\displaystyle\begin{aligned} m\angle QPT & = (6x+20)^\circ \\ \\ & = (6(15)+20)^\circ \\ \\ & = (90 +20)^\circ \\ \\ & = 110^\circ\end{aligned}[/tex]
In conclusion, our answer is A.
Find the Slope of the line graphed?
Answer:
-1/2
Step-by-step explanation:
It is negative since the slope is declining, meaning that it is a negative slope!
It is 1/2 because we go down one and move 2 to the right, meaning that we get 1/2 and then for the negative slope get -1/2
Consider marking this as brainliest it really helps!

Step-by-step explanation:
Samantha is deciding between two different movie streaming sites to subscribe to. Plan A costs $18 per month plus $1 per movie watched. Plan B costs $14 per month plus $2 per movie watched. Let A represent the monthly cost of Plan A if Samantha watches x per month, and let B represent the monthly cost of Plan B if Samantha watches x movies per month. Graph each function and determine the number of monthly movies watched, x, that would make the two plans have an equal monthly cost.
Answer:
Samantha would have to watch 4 Movies so x=4

+(a+b)a+ab=(a+a)(a+b). To find a and b, set up a system to be solved.
a+b=−13
ab=42
Since ab is positive, a and b have the same sign. Since a+b is negative, a and b are both negative. List all such integer pairs that give product 42.

Calculate the sum for each pair.
−1−42=−43
−2−21=−23
−3−14=−17
−6−7=−13
The solution is the pair that gives sum −13.
a=−7
b=−6
Rewrite factored expression (a+a)(a+b) using the obtained values.

To find equation solutions, solve a−7=0 and a−6=0.

Answer:
x = 63.34 degree
Step-by-step explanation:
2x-10 + x = 180 as al straight lines add up to 180 degrees
3x -10 = 180
+ 10 +10
3x = 190 add 10 to both sides as shown to cancel left side
x = 190/3
x = 63.33334 degree to 5 dp
x = 63.34 degree to 2 dp.

The coordinates of the vertices of the preimage of a triangle are (2, 1), (3, 4), and (4, 1). The coordinates of the vertices of the image are (3, 3), (4, 6), and (5, 3). How far and in what direction was the triangle translated?
May I please receive help?
Answer:
slope of line 1
m = (-8 - 2) / (2 + 2)
m = -10/4 = -5/2
slope of line 2
m = (6 + 1) /(5 - 0)
m = 7/5
slope of line 3
m = (-2 + 7) /(2 - 4)
m = 5/ -2
m = -5/2
Line 1 and Line 2 are neither.
Line 1 and Line 3 are parallel since they have same slope.
Line 2 and Line 3 are neither.

suppose PQR is rotated 180° about the origin, (0,0). find the coordinates of P', Q', and R'. then sketch P'Q'R'
(type an ordered pair)
P'=___
Q'=___
R'=___
Answer:
I think the way they are telling is that the triangle will move to the third quadrant,
If so, then the coordinates of P'Q'R' will just be the negative of PQR.

82
A) 77°
C) 82
B) 75
D) 127°
Answer:
c) 82
Step-by-step explanation:
It's 82 degrees because of the opposite interior angle theorem, which means that those two angles are the same, as well as any pair of opposite interior angles.
Lin’s job pays$8.25 an hour plus$10 of transportation allowance each week. She has to work at least 5 hours a week to keep the job, and can earn up to $175 per week (including the allowance). 1.Represent this situation mathematically. If you use variables, specify what each one means. 2.How many hours per week can Lin work? Explain or show your reasoning.
Answer:
20
Step-by-step explanation:
($8.25 x 5 hours) + 10x <= 175
41.25 + 10x <= 175
x =4 that is 4 weeks
so multiple 5 hours by 4 to get 20 hours
that way she is earning 175 per week

The price p in dollars and the quantity x sold of a certain product obey the demand equation -1/5x+100 (0≤ x ≤ 500)
a) Express the revenue R as a function of x. (remember, R= p.x)
b) What is the revenue if 200 units are sold?
c) What quantity x that maximizes the revenue?
e) What price should the company charge to maximize revenue?
Answer:
See belowStep-by-step explanation:
We have:
p = -1/5x + 100 = -0.2x + 100a) The revenue is:
R = px R = x( -0.2x + 100)R= -0.2x² + 100xb) x = 200, find R:
R = -0.2(200²) + 100(200) = 12000c) This is a quadratic function and the maximum value is obtained at vertex.
x = -100/(-0.2*2) = 250 is the required quantityd) The max revenue is obtained when -0.2x + 100 at max:
The maximum possible is p = 100 when x = 0Hello Everyone! If you are having any difficulties in Math book D1 and D2, then do tell me in the channel discussion section.

The algebraic inequality will be (3x + 4) / 4 > 3. Then the value of x will be greater than 8/3.
What is inequality?Inequality is defined as an equation that does not contain an equal sign. Inequality is a term that describes a statement's relative size and can be used to compare these two claims.
I think of a number.
Let the number be 'x'.
Then I multiply it by 3. Then the expression will be
⇒ 3x
Then I add 4. Then the expression will be
⇒ 3x + 4
Then I divide the answer by 4. Then the expression will be
⇒ (3x + 4) / 4
My final answer is 3 less than the number I thought of at the beginning. Then we have
(3x + 4) / 4 > 3
Simplify the equation, then the value x will be
(3x + 4) / 4 > 3
3x + 4 > 12
3x > 8
x > 8/3
The algebraic inequality will be (3x + 4) / 4 > 3. Then the value of x will be greater than 8/3.
