Answer:
-10 because you do parenthesis first
Answer:
x = -10
Step-by-step explanation:
3(-2x - 3) + 4x - 3 = 8
~Simplify
-6x - 9 + 4x - 3 = 8
-2x - 12 = 8
~Add 12 to both sides
-2x = 20
~Divide -2 to both sides
x = -10

The new bookcase for your future dorm room has the dimensions of 24 in wide by 12 in deep by 36 in tall. If one average textbook has the dimensions of 8.5 in wide by 11 in long by 1.5 in tall, how many books could you fit on your bookshelf with no shelving?
Answer:
About 73.93 books. Round that to 73 books, because you can't place 93% of a book.
Step-by-step explanation:
You first calculate to dimensions of the bookcase, then you calculate the dimensions of the books. As a result, divide the calculation of the bookshelf by the calculation of the books, and you should have your answer.
What is the y-intercept of the function f(x) = -2/9x+1/3

Answer:
(x, y, z) = (2, 2, -1/2)
Step-by-step explanation:
Most manual solutions to a system of 3 equations in 3 unknowns are ad hoc. The idea is to take advantage of any relationships that might exist between the coefficients.
Multiply the first equation by 2, then subtract the third equation.
2(2x -y -4z) -(x -2y) = 2(4) -(-2)
4x -2y -8z -x +2y = 8 +2 . . . . . . . eliminate parentheses
3x -8z = 10 . . . . . simplify
Now, we can subtract this from the second equation:
(3x -2z) -(3x -8z) = (7) -(10)
6z = -3 . . . . . . . simplify
z = -1/2 . . . . . . . divide by 6
Using the second equation, we can find x:
3x -2(-1/2) = 7
3x = 6 . . . . . . . . subtract 1
x = 2 . . . . . . . . . divide by 3
Using the last equation, we can find y:
2 -2y = -2
1 -y = -1 . . . . . . divide by 2
y = 2 . . . . . . . . add y+1
The solution is ...
(x, y, z) = (2, 2, -1/2)

6. A rectangle has a perimeter of 62 feet. If its length is 9 feet longer than its width, find
the dimensions of the rectangle.
62ft
Answer:
length = 20 ft, width = 11 ft
Step-by-step explanation:
let w be width, then length = w + 9
The opposite sides of a rectangle are equal , then
2w + 2(w + 9) = 62
2w + 2w + 18 = 62
4w + 18 = 62 ( subtract 18 from both sides )
4w = 44 ( divide both sides by 4 )
w = 11
and w + 9 = 11 + 9 = 20
then width = 11 ft and length = 20 ft

Using the numbers 2,7,13,11,5 can you get the total of 23? (You must use all numbers, no negatives, no using each number more than once, and only use Subtraction, Multiplication, addition, and division, you can also group numbers)
Answer:
(2-7)/5 + 13 + 11
Step-by-step explanation:
There's a lot of guess and check that needs to go into this to make this work, but here's what I got:
(2-7)/5 + 13 + 11
-5/5 + 13 + 11
-1 + 13 + 11

D(x)=\dfrac{1}{36}(x-60)^2-100D(x)=
36

(x−60)
2
−100D, left parenthesis, x, right parenthesis, equals, start fraction, 1, divided by, 36, end fraction, left parenthesis, x, minus, 60, right parenthesis, squared, minus, 100
What is the lowest altitude Ying will reach?
Answer:
The lowest point is -100 meters, or 100 meters down
Step-by-step explanation:
D(x)=1/36(x-60)^2-100
This equation is in vertex form
y = a(x-h)^2 +k where (h,k) is the vertex
Since a is positive, the parabola opens up
The vertex is the minimum, which means it will be the lowest point
The vertex is (60,-100)
The lowest point is -100 meters, or 100 meters down
Given expression
y=1/36(x-60)²-100Compare to the vertex form
y=a(x-h)²+kWe get
.
a=1/36(h,k)=vertex=(60,-100)As a is positive parabola is opening upwards and vertex is minimum
Lowest altitude is -100m

Find a polynomial f(x) of degree 4 that has the following zeros. 2, 5, 0, -7
Answer:
Step-by-step explanation:
f(x) = (x - 2)(x - 5)x(x+ 7)
f(x) = (x^2 - 7x + 10)*x * (x + 7)
f(x) = x(x^3 - 39x + 70)
f(x) = x^4 - 39x^2 + 70x

Answer: Ray AC is correct
This is because ray AE points in the same direction along ray AC. Put another way, points C and E are on the same line as A. So relabeling from "ray AE" to "ray AC" does not change the ray itself.
Keep in mind that order is important. So saying "ray AE" is completely different from "ray EA" due to the fact that the first letter is the endpoint while the second letter is where the ray goes on forever. So we can think of starting at point A and going in the direction of E to get ray AE, or going in the direction of C to get ray AC, and we're talking about the same ray.
