Which of these does NOT describe an equivalent ratio or rate? A) 10:35 and 8:28 B) 4:10 and 10:25 C) 40km/h and 0.06 km/min D) 1.5L for $2.30 and 7.5 L for $11.50
Answer:
C
Step-by-step explanation:
convert option a to the lowest term
10 : 35 = 2: 7 (divide both ratios by 5)
8 : 28 = 2 : 7 (divide both ratios by 7)
convert option b to the lowest term
4 : 10 = 2 : 5 (divide both ratios by 2)
10 : 25 = 2 : 5 (divide both ratios by 5)
option c
divide 40km/h by 60 to convert to km / min
40/60 = 0.7 not equivalent
option d

A certain quadratic function has x-intercepts at 2 and 3. What are the x-coordinates of its vertex?
a)7/2
b)1/2
c)3/2
d)5/2
Answer:
D
Step-by-step explanation:
The equation is going to by
y = (x - 2)(x - 3) Multiply to remove the brackets.
y = x^2 - 2x - 3x + 6
y = x^2 - 5x + 6 Now what you are going to do is complete the square.
y = (x^2 - 5x + __ ) +6
Take - 5
Divide it by 2 = -5 / 2
and square it = (-5 / 2)^2 = 25/4
Put this result inside the brackets.
y = (x^2 - 5x + 25/4 ) + 6 Now subtract 25/4 after the 6
y = (x^2 - 5x + 25/4) + 6 - 25/4
y = (x - 5/2)^2 - 1/4
The x coordinate of the vertex is 5/2
You could also do this by using x = -b/2a = - -5/2*1 = 5/2

The graph below is the graph of a function true or false
Answer:
you did not add a picture so i cannot help you i am very deeply sorry so sorry i apologize baahhahahahahahahahahahahahah
Step-by-step explanation:
A coordinate plane with 2 lines. The first line is labeled y equals f(x) and passes through (negative 1, 2), (0, 2), and (2, 2). The second line is labeled y equals g(x) and passes through (negative 0.5, negative 2), points at (0, negative 1), and (1, 1). The lines intersect at (1.5, 2).
Use the graph to determine the input value for which f(x) = g(x) is true.
Answer:
x=2/3
Step-by-step explanation:
Most of that information is unnecessary. Just plug in the values of f(x) and g(x) into the equation where they are equal to each other and solve.
-3x+4=2
-3x=-2
3x=2
x=2/3
Earth contains water and oxygen molecules. Each mass is given below. Which has the greater mass? Explain how you know.
water = 2.99 × 10-26 kg
oxygen = 2.66 × 10-26 kg
Answer:
The water molecule has the greater mass because 2.99 is greater than 2.66. After comparing the exponents, which are the same, the coefficients are compared to determine the molecule with the greater mass.

The function (x) is represented by this table of values
Answer:
Step-by-step explanation:
Average rate of change of a function between interval x = a and x = b is given by,
Average rate of change = [tex]\frac{f(b)-f(a)}{b-a}[/tex]
Average rate of change of the function in the interval [-4, -2]
= [tex]\frac{f(-2)-f(-4)}{-2-(-4)}[/tex]
= [tex]\frac{0-(-12)}{-2+4}[/tex]
= 6
Average rate of change in the interval [-2, 1]
= [tex]\frac{f(1)-f(-2)}{1-(-2)}[/tex]
= [tex]\frac{3-0}{1-(-2)}[/tex]
= 1
Average rate of change in the interval [-3, 1]
= [tex]\frac{f(1)-f(-3)}{1-(-3)}[/tex]
= [tex]\frac{3-(-5)}{1+3}[/tex]
= 2
Average rate of change in the interval [-4, 0]
= [tex]\frac{f(0)-f(-4)}{0-(-4)}[/tex]
= [tex]\frac{4-(-12)}{0-(-4)}[/tex]
= 4
Solve this URGENT! Differentiation
Instead of using the quotient rule, you can first expand y :
y = (4x - 1)^2 / x ^2 = (16x ^2 - 8x + 1) / x ^2 = 16 - 8/x + 1/x ^2
Then the derivative is
dy/dx = -8/x ^2 - 2/x ^3
The tangent to the curve at (-1, 25) then has a slope or gradient of
dy/dx = -8/(-1)^2 - 2/(-1)^3 = -6
Use a number line to help you find the sum of -24+8
Answer:
-16
Step-by-step explanation:
When adding a negative and a positive number, you need to keep in mind that your are essentially adding.
so if I have a number line
-24, -23, -22, -21, -20, -19, -18, -17, -16, -15, -14,,,,
you will start at -24 and will go up the number line (to the right) 8 times and that should get you your answer.
What is the value of X please help
Answer:
x= 20
Step-by-step explanation:
The sum of the angles of a triangle are 180 degrees
x+5 + 7x-5 + x =180
Combine like terms
9x = 180
Divide by 9
9x/9 = 180/9
x = 20
A school bus can hold a maximum of 45 students. The correct inequality for this word problem is b ≤ 45. Why did I use ≤ not < in this problem?
Answer:
This sign ≤ means greater than or equal to
but, this sign < means the number which is in the side is only greater
That why the sign ≤ is used
My this answer might be wrong , because in b ≤ 45 , I am confused from where the letter " b " came from .

Answer:
I think its C but I'm not sure
Step-by-step explanation:
I'm so sorry if it is wrong!!
Option D is correct, the equation represented by the function g(x) is ∛x - 1.5.
The graph of g(x) is a translation of y =∛x
We have to find the equation which represents the g(x).
if x=9 then the value of y is 3 in the f(x).
For the translation of the graph y = ∛x would be in the form g(x) = ∛(x - h) + k, where (h, k) represents the horizontal and vertical shifts of the graph, respectively.
There is a vertical shifts in the translation.
As we observe the function when x is 9 the y value is decreased by 1.5.
So the function g(x) would be ∛x - 1.5.
Hence, the equation represented by the function g(x) is ∛x - 1.5.

If S lies between R and T, RT=21, RS=2X+5, and ST=3x-4. Find RS and ST
Answers:
RS = 13
ST = 8
==================================================
Explanation:
S is between R and T. I'm assuming also that S is on line RT.
If that's the case, then by the segment addition postulate, we can say RS+ST = RT.
In other words, the longest segment RT is broken into two smaller pieces RS and ST (not necessarily equal but they may be). Gluing the pieces back together should get us the original longest segment.
---------------
Apply substitution and solve for x.
RS+ST = RT
(2x+5)+(3x-4) = 21
(2x+3x)+(5-4) = 21
5x+1 = 21
5x = 21-1
5x = 20
x = 20/5
x = 4
--------------------
If x = 4, then,
RS = 2x+5 = 2*4+5 = 13ST = 3x-4 = 3*4-4 = 8Then notice how RS+ST = 13+8 = 21, which is is the length of RT
This confirms that RS+ST = RT is true and it confirms our answers.
