Answer:
See explanation
Step-by-step explanation:
This is a parabola that opens down with the vertex at (-1, 4) So, find (-1, 4) on your graph. Now, find y for x = 0 and x = 1 which will give you two points on the parabola. Since the parabola is symmetrical, find the points that are the partners to the two points you just found. That should give you a good idea as the graph.
when x = 0,
y = -2(0 + 1)^2 + 4 = -2(1) + 4 = 2 so (0, 2) is on the graph
when x = 1,
y = -2(1 + 1)^2 + 4 = -2(2)^2 + 4 = - 8 + 4 = -4 so (1, -4) is on the graph
Symmetry gives the point (-2, 2) as the partner to (0, 2) and
(-3, -4) as the partner to (1, -4)
I don't have graph paper to show you that, you are going to have to graph those 5 points ((-1, 4), (0, 2), (1, -4), (-2, 2), (-3, -4)) and draw the parbola.
I hope this helps. OK?

Janice bought 3 hamburgers and 4 hotdogs for her cousins and paid $8.50. Brian bought 3 hamburgers and 6 hotdogs for his cousins and paid $10.50. How much did one hamburger cost?
A) 2.00
B) 1.50
C) 1.00
D) 0.75
Answer:
Cost of each hamburger = $1.50
Step-by-step explanation:
Given:
Cost of 3 hamburger and 4 hotdog = $8.50
Cost of 3 hamburger and 6 hotdog = $10.50
Find:
Cost of each hamburger
Computation:
Cost of each hamburger = h
Cost of each hotdog = d
So,
3h + 4d = 8.50.....EQ1
3h + 6d = 10.50.......EQ2
EQ2 - EQ1
2d = 2
d = 1
3h + 4d = 8.50
3h + 4(1) = 8.50
3h = 4.50
h = 1.50
Cost of each hamburger = $1.50
Select the three expressions that are equivalent to 2 (4 - 3x) + (5x-2)
Answer:
The answer correct the questions is 11x-10
Answer:
Step-by-step explanation:
2 (4 - 3x) + (5x-2) can be solved in several basic steps. First, distribute multiplication in 2(4 - 3x), obtaining 8 - 6x and (overall) 8 - 6x + 5x - 2.
Combine like terms: -x = -10, or x = 10
help fast please please please
Answer:
1). The correct answer is letter A)
6). The correct answer is letetr D)
Step-by-step explanation:
Let be the equation of a sin function:
[tex]sin(x)=Asin(B(x+C))+D[/tex]
Where:
A is the amplitudeThe period is 2π/BC is the phase shift leftD is the vertical shiftWe can see from the image of the problem (6):
The amplitude is: A = 3 units
The vertical shift is: D = 6 units
The phase shift is: C = π
The period is : P = 4π = 2π/B then B = 1/2
Therefore the correct answer is letetr D)
[tex]sin(x)=3sin(0.5(x+\pi))+6[/tex]
In the problem (1) we have:
The amplitude is: A = -2 units
The vertical shift is: D = 6 units
The phase shift is: C = π/4
The value of B = 1
Then the correct answer is letter A)

Answer:
x = 20
Step-by-step explanation:
These 2 angles are supplementary so they add up to 180:
3x - 10 + 5x + 30 = 180
8x + 20 = 180
8x = 160
x = 20
A scuba diver was rising back to the surface after taking photos under water. At 2:50 P.M.,
he was at an elevation of 15.3 feet. At 2:55 P.M., the diver’s depth was 3.7 feet. By how
many feet did the diver’s position change from 2:50 P.M. to 2:55 P.M.
Answer:
the answer is 11.6 feet
Step-by-step explanation:
you simply subtract the feet of the depth he was at at 2:55pm from his depth at 2:50pm

Step-by-step explanation:
A textbook company will ship a box of textbooks to college students. The weight of the box in pounds can be determined by the function w(x) = 7.5x + 2, where x is the number of textbooks in the box. The company requires a student to order at least 2 books but not more than 6 books. What is the range of the function for this situation? *
A. 2 ≤ x ≤ 6
B. 17 ≤ y ≤ 47
C. {17, 24.5, 32, 39.5, 47}
D. {2, 3, 4, 5, 6}
Answer:
I think its D
Step-by-step explanation:
It's obviously not A, because A has an x instead of y. B makes no sense because the range is 2-6. C makes no sense. D is the only logical answer.
The range of the function for this situation is 17 ≤ w ≤ 47
An equation is an expression used to show the relationship between two or more variables.
Let x represent the number of textbooks in the box
The company requires a student to order at least 2 books, hence:
x ≥ 2.
w(2) = 7.5(2) + 2 = 17
Also they do not require more than 6 books, hence:
x ≤ 6
w(6) = 7.5(6) + 2 = 47
The range of a function is the set of possible dependent variables.
Hence, the range of the function for this situation is 17 ≤ w ≤ 47

The average age of the ten people on my basketball team was 13.5, but then a fifteen year old joined our team and an 11 year old quit the team. What is the average age of my team now?
Answer:
The new average is 134/10, or 13.4 years.
Step-by-step explanation:
a + b + c + d + e + f + g + h + i + j
------------------------------------------------ = 13.5 (the original average)
10
15 years is 1.5 year older than the 13.5 average and 11 years is 2.5 younger than that. The net change is 1.5 - 2.5, or -1. The number of players remains the same: 10. We subtract 1 from the sum of the player ages and divide the result by 10:
a + b + c + d + e + f + g + h + i + j - 1
--------------------------------------------------- = 13.4 (the new average)
10
Note that the sum of the original 10 ages is (10)(13.5), or 135, which becomes 134 after the 15-year-old joined the team and the 11 year old quit. The new
average is 134/10, or 13.4 years.

Hii!
___________________________________________________________
Answer:
Slope is 7! ^^
Step-by-step explanation:
Note that the equation is given to us in slope intercept.
The slope intercept formula is y=mx+c.
m=slope
c=y intercept.
In the equation y=mx+c m denotes the slope.
In the equation y=7x-5, 7 is the slope.

question in screenshot
Answer:
∠ A ≈ 24.1°
Step-by-step explanation:
Using the law of sines , then
[tex]\frac{9}{sinA}[/tex] = [tex]\frac{21}{sin72}[/tex] ( cross- multiply )
21 × sinA = 9 × sin72° ( divide both sides by 21 )
sinA = [tex]\frac{9sin72}{21}[/tex] , then
∠ A = [tex]sin^{-1}[/tex] ( [tex]\frac{9sin72}{21}[/tex] ) ≈ 24.1° ( to the nearest tenth )
1/3 divided by 5/8
