Answer:
The answer is B
Step-by-step explanation:
1. What is the value of x in the equation 4x – 2(x + 3) = 8? (LT 1a)
a. x = 1 b. x = 2.5
C. X = 3.5
d. x = 7
Answer:
D
Step-by-step explanation:
4x - 2(x + 3) = 8
Use distributive property
4x -2x - 6 = 8
2x - 6 = 8
2x = 8 + 6
2x = 14
x = 14 ÷ 2
x = 7

C. no solution
D. infinitely many solutions
Hurry !
Answer:
A (0, 10)
Step-by-step explanation:
Answer:
D its
Step-by-step explanation:
Since x+y = 10-----(1)
And 3x+3y = 30----(2)
We can see from (2) that 3(x+y) =30;
Also same as saying x+y = 30/3 which is equivalent to x+y = 10.
So in this case we have many possible values
x = 0, y = 10 and vice versa
x = 1, y = 9 and vice versa
x = 2, y = 8 and so on
So the question has a lot of solutions
To determine the number of trout in a lake, a conservationist catches 120 trout, tags them and throws them back
into the lake. Later, 44 trout are caught; 11 of them are tagged. How many trout would the conservationist expect
to be in the lake?
Answer:350 Trouts
Step-by-step explanation:To determine the number of trouts the conservationist expect to be in the lake, you add 120+120 that equal to 240.Then you add 240+40 that equals to 284.Then you add 284+44 that equals to 328.Then you add 328+11 that equals to 339.Finally, you add 339+11 to get your answer:350.
The weights of Sarus crane chicks and hooded crane chicks H (both in grams) during the 10 days following hatching can be modeled by the functions S = –0.122t3 + 3.49t2 – 14.6t + 136 H = –0.115t3 + 3.71t2 – 20.6t + 124 where t is the number of days after hatching. According to the models, what is the difference in weight between 5-day-old Sarus crane chicks and hooded crane chicks? Round your answer to the nearest thousandth, if necessary.

John Muir was an American naturalist born in Scotland on April 21, 1838. As one of the first advocates of the United States' wilderness preservation, Muir spent his career writing letters, essays and books about many of his experiences in the Sierra Nevada mountains, located in northern California. Muir's influence on the history of American wilderness continues to live on past his death (in the early twentieth century) as people of all ages visit and hike through the 221 miles of the John Muir Trail, named in Muir's honor. The trail begins in Yosemite National Park and concludes at Mount Whitney, which contains the highest peak of the continental United States. The following table compares Mount Whitney"s height, in meters, to other monumental peaks of the world.

I don’t understand this someone pls help me! (Question 10)
Answer:
a. f(n) = n(n+1)/2
b. 351
c. 19
d. no; n would not be an integer for f(n) = 17.
Step-by-step explanation:
a. The terms are 1, 3, 6, 10, ...
Each term has the term number added to the previous term. That is, first differences are 3-1 = 2, 6-3 = 3, 10-6 = 4. These differences have a constant difference of 1.
When the 2nd differences are constant, a 2nd degree polynomial can describe the sequence. It is a little bit of trouble to find that polynomial.
For the polynomial ...
[tex]f(n)=an^2+bn+c[/tex]
We can substitute values for n and f(n) to get 3 equations in 3 unknowns:
[tex]1=a\cdot1^2+b\cdot1+c\\\\3=a\cdot2^2+b\cdot2+c\\\\6=a\cdot3^2+b\cdot3+c[/tex]
Solving these equations by your favorite method gives ...
(a, b, c) = (1/2, 1/2, 0)
That is, the function representing the relationship is ...
f(n) = n(n+1)/2 . . . . the function describing the relationship
__
b. f(26) = 26(27) = 13(27) = 351 . . . . the number of squares in term 26
__
c. The number of the term having 190 squares can be found by solving ...
n(n +1)/2 = 190
n(n +1) = 380 = 19(20)
The 19th term will have 190 squares.
__
d. Terms 5 and 6 are 15 and 21.
17 is not the value of one of the terms in this sequence.

[tex]y = -6[/tex] or the y-intercept coordinates, [tex](0,-4)[/tex].
Solution:Simplifying the equation into standard form:
[tex]4y = 10x - 24 \\ 4y - 10x = - 24[/tex]
Finding the x-intercept by evaluating (x,0):
[tex]4(0) - 10x = - 24 \\ - 10x = - 24 \\ x = \frac{ - 24}{ - 10} \\ x = \frac{12}{5} [/tex]
Finding the y-intercept by evaluating (0,y):
[tex]4y - 10(0) = - 24 \\ 4y = - 24 \\ y = \frac{ - 24}{4} \\ y = - 6[/tex]

The school zone in front of your school has a posted speed limit of 25mi/h which is about 11 m/s. Let’s examine the stopping of car is several different situations. The crossing guard holds up her stop sign, and the driver is paying attention as well. The car moves at a constant velocity of 11 m/s for 2.3 second while the driver reacts, then slows down at a constant rate or -4.5 m/s. What is the stopping distance for the car in this situation?
Answer:
x=13.4
Step-by-step explanation:
x=v_i(t)+1/2(at^2 )
x=11(23)+12(-4.5)(2.3)^2
x=25.3-11.9
x=13.4
The stopping distance for the car in this situation will be x = 13.4 meters.
What is an equation of motion?Equations of motion are used to describe how a physical system behaves in terms of how its motion changes over time.
The behavior of a physical system is described in more detail by the equations of motion as a collection of mathematical functions expressed in terms of dynamic variables.
Given that the school zone in front of your school has a posted speed limit of 25mi/h which is about 11 m/s. The car moves at a constant velocity of 11 m/s for 2.3 seconds while the driver reacts, then slows down at a constant rate of -4.5 m/s.
The distance will be calculated as below:-
x=v(t)+1/2(at² )
x=11(23)+12(-4.5)(2.3)²
x=25.3-11.9
x=13.4 meters
Therefore, the stopping distance for the car in this situation will be x = 13.4 meters.

1. area of a triangle = 1/2 b h where b=6 , h=3
A1 = 1/2 (6) 3 = 9
2. area of trapezoid = a + b * (h/2) here a = 4, b = 6, h = 5
A2 = (4 + 6 ) * 5/2 = 25
3. area of a triangle = 1/2 b h where b=8 , h=6

Write an equation of the line that passes through the point P(0,0) and is perpendicular to the line y=-5x+3
Answer:
[tex]y=\frac{1}{5}x[/tex]
Step-by-step explanation:
We want to write an equation of a line that passes through the point P(0, 0) and is perpendicular to the line y=-5x+3.
First, let's figure out the slope of our new line. Remember that slopes of perpendicular lines are negative reciprocals of each other.
So, to find our new slope, we need to flip our old slope and multiply by -1. So, our new slope is:
[tex]-5[/tex]
Flip:
[tex]-\frac{1}{5}[/tex]
Multiply by a negative:
[tex]=\frac{1}{5}[/tex]
So, the slope of our new line is 1/5.
To find our equation, we can use the slope-intercept form:
[tex]y=mx+b[/tex]
Where m is the slope and b is the y-intercept.
As previously determined, our slope is 1/5.
Note that (0, 0) is our y-intercept (and also our x-intercept). So, substitute 0 for b. Therefore, our new equation is:
[tex]y=\frac{1}{5}x+0[/tex]
Simplify:
[tex]y=\frac{1}{5}x[/tex]
And we're done!
