Answer:
100 miles
Step-by-step explanation:
y=.55m+50 equation 1
y=.50m+55 equation 2
.55m+50=.50m+55 substitute value of y in equation 1 into equation 2
.05m=5
m=100
check answer by substituting 100 into both equations.
Y=.55(100)+50
y=55+50
y=105
y=.50m+55
y=.50(100)+55
y=50+55
y=105
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

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 .
a line is perpendicular to
y= -1/4x -9
what is the slope of this perpendicular line?
Reason: Any two perpendicular lines will have their slopes multiply to -1, where neither line is vertical.
The given line has slope -1/4 and the perpendicular slope is 4
(-1/4)*4 = -1
Put another way: the answer is 4 because it's the negative reciprocal of -1/4.

. In a state with a sales tax rate of 6%,
Alex bought paper for his printer for
$17.99. How much was his sales tax
to the nearest penny?
Answer:
$1.1
Step-by-step explanation:
In a state with a sales tax rate of 6%,
Alex bought paper for his printer for
$17.99.
The amount of his sales tax to the nearest penny is calculated as:
Sales tax rate × Cost of Paper for his printer
Sales tax = 6% × $17.99
= 6/100 × $17.99
=$ 1.0794
Approximately≈ $1.1

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

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.

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

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.
