Answer:
x = 3
Step-by-step explanation:
Subtract 8x from both sides.
3x+4−8x=8x−11−8x
−5x+4=−11
Subtract 4 from both sides.
−5x+4−4=−11−4
−5x=−15
Divide both sides by -5.
−5x
−5
=
−15
−5
x=3

What is the mZACB?
O 10°
B
O 50°
(4x)
O 90°
O 180°
(7x-20)
C
Answer:
50 degrees
Step-by-step explanation:
The total sum of angles in a triangle is 180, thus the value of ∠ACB will be obtained as follows:
Given that the triangle is a right triangle, the sum of angles will be:
(4x)°+(7x-20)°+90=180
simplifying and solving for x we get:
4x+7x-20+90=180
11x=180+20-90
11x=110
dividing both sides by 11 we get:
(11x)/11=110/11
this gives us
x=10°
Thus substituting the value of x in:
∠ACB=(7x-20)°
=(7*10-20)
=70-20
=50°
Answer: 50°
Triangle FGH has vertices F(−5, 0), G(0, 5), and H(5, 0). A dilation, centered at the origin, is applied to this triangle. The image has vertices F′(−30, 0), G′(0, 30), and H′(30, 0).
What is the scale factor of this dilation?
Answer:
The scale factor of the dilation is 6.
Step-by-step explanation:
Dilation of a Triangle
A dilation is a transformation that produces an image that is the same shape as the original but at a different size.
Dilating a point centered at the origin means multiplying its coordinates by a fixed scale factor k.
If point A(3,6) is dilated centered at the origin by a scale factor of 4, then its new coordinates are A'(12,24).
Triangle FGH has vertices F(−5, 0), G(0, 5), and H(5, 0).
It's known a dilation, centered at the origin, is applied to this triangle and the image has vertices F′(−30, 0), G′(0, 30), and H′(30, 0)
Comparing the coordinates F and F', the x-coordinate is scaled by a factor of (-30)/(-5)=6
Comparing the coordinates G and G', the y-coordinate is scaled by a factor of (30)/(5)=6
Comparing the coordinates H and H', the x-coordinate is scaled by a factor of (30)/(5)=6
Since all the scale factors are the same, we can conclude the scale factor of the dilation is 6.
Answer:
the answer will be 6

Step-by-step explanation:
To rent a certain meeting room, a college charges a reservation fee of $38 and an additional fee of $6.80 per hour. The history club wants to spend less than $65.20 on renting the meeting room. History club wants to spend less than $65.20 on renting the meeting room. What are the possible amounts of time for which they could rent the meeting room? Use t for the number of hours the meeting room is rented, and solve your inequality for t.
Answer:
t < 4
Step-by-step explanation:
Reservation fee = $38
Additional fee per hour = $6.80
The history club wants to spend less than $65.20 on renting the meeting room.
t = number of hours the meeting room is rented
The inequality is
38 + 6.80t < 65.20
6.80t < 65.20 - 38
6.80t < 27.20
t < 27.20 / 6.80
t < 4
Therefore, number of hours the meeting room is rented should be less than 4 hours

.Chelsea graphs a proportional relationship. Bradyn graphs a line that passes through the origin. What do you know about the y-intercept of each student’s graph? Explain your answer.
Answer:
If the graph of the line passes through the origin, it means that the graph has no y-intercept
Step-by-step explanation:
Here, we want to interpret the y-intercept of a graph that passes through the origin
If the y-intercept of a graph passes through the origin, it means that the value of the y-intercept is zero
In other words, the graph has no intercept on either the y or x axes
while holding her cat, Mya steps on a scale, the scale reads 127 pounds. Alone, Mya weighs 112 pounds. Write an addition equation to find the weight of Mya's cat.
Answer:
127+(-112)=15
Step-by-step explanation:
If you subtract 112 from 127, you can find the difference. Since 112 is Mya's weight, and the total is 127, we need to find out how much weight is left over after we take away Mya's weight, which would be the cat's weight. So if you follow the expression, which is 127+(-112), you would get a sum of 15 pounds. Since this is an addition problem, the expression would be 127+(-112) instead of 127-112. I hope you understand. The difference between 127 and 112 is the cat's weight, so the cat weighs 15 pounds.

an airplane begins to descend for a landing. the elevation g (in feet) of the airplane is modeled by the function: g(t)= 4800-300t, where t is the time (in minutes) since the airplane began to descend. what is the y- intercept?
Answer:
The y-intercept in this case is 4800
Step-by-step explanation:
The equation of a line graph is ;
y = mx + c
with respect to the given equation in the question, the y-intercept in this case is 4,800
In this case the y-intercept represent the height from which the plane starts to descend
Kerry is looking foward to a skiing trip this weekend she checked the tempature yesterday and today, and overnigjt is dropped from 12 F to -5 F what is the total difference in the tempature
Answer:
-[tex]17^\circ F[/tex]
OR
[tex]17^\circ F[/tex] decrease in the temperature.
Step-by-step explanation:
Given that:
Temperature at the night = [tex]12^\circ F[/tex]
Temperature in the morning = -[tex]5^\circ F[/tex]
To find:
The total difference in the temperature = ?
Solution:
Difference of any quantity is given by the Final value of quantity minus Initial value of quantity.
Therefore, the difference is given as : -[tex]5^\circ F[/tex] - [tex]12^\circ F[/tex] = -[tex]17^\circ F[/tex]
Negative value in the difference indicates that there is a decrease of the quantity.
So, the answer is:
-[tex]17^\circ F[/tex]
OR
there is decrease of [tex]17^\circ F[/tex] in the temperature.
