The graph represents the speed at which Pete’s marble travels. The speed of Stephano’s marble is represented by the equation f=2.25s, where f is the distance in feet and s is the time in seconds. Whose marble will reach the 6-foot mark sooner?
Answer:
Note. There is a mismatch between the graph and the equation
------------------------------
As per the graph, 6 ft is reached at 4 secondsThe graphed line is f = 1.5s------------------------------
If we go by the equation, then:
f = 2.25s6 = 2.25ss = 6/.2,25s = 2.67 secondsAt the baseball field, a bag of candy is $2.50 and a bag of popcorn is $4.25. John is planning to purchase 3 boxes of candy and x bags of popcorn. Write an equation to find y, the total price John must pay.

The heights of the apple trees in an orchard are normally distributed with a mean of 12.5 feet and a standard
deviation of 1.2 feet. What percentage of the apple trees are between 10.1 and 13.7 feet tall?
Answer:
18.141%
Step-by-step explanation:
We start by calculating the z-scores
Mathematically;
z-score = (x-mean)/SD
for 10.1
z = (10.1-12.5)/1.2 = -2
for 13.7
z = (13.7-12.5)/1.2 = 1.2/1.2 = 1
So we need the probability within this range
P(-2 < x < 1)
We can check the probability using the standard normal distribution table
That will be;
P(-2 < x < 1) = 0.18141
Converting this to percentage, we have 18.141%
Consider the equations shown: ax + by = ab & 2ax + 3by = 3b
Which of these is the value of y in terms of a?
Option 1 : y = 3a – 35
Option 2 : y = 2ab – 3b
Option 3 : y = 9a – 35
Option 4: y = 3 – 2a
Answer: [tex]y=3-2a[/tex], Option 4
Step-by-step explanation:
[tex]\left \{ {ax + by = ab} \atop {2ax + 3by = 3b}} \right.[/tex]
multiply 2 at [tex]ax+by=ab[/tex]
[tex]2ax+2by=2ab[/tex]
subtract [tex]2ax + 3by = 3b[/tex] and[tex]2ax+2by=2ab[/tex]
[tex]by=3b-2ab[/tex]
[tex]y=3-2a[/tex]
If y= 5x-2 and x= 4b+3 then y is equivalent to which of the following
Answer:
y = 20b + 13
Step-by-step explanation:
From the above, we want to get y
Using the given d value, we simply proceed to substitute
y = 5x-2
x = 4b + 3
Substituting x-values, we have
y = 5(4b + 3)-2
y = 20b + 15-2
y = 20b + 13

what is the intermediate step in form (x+a)^2=b as a result of completing the square of the following equation
6x^2+72x-170=-2
Answer:
6x² + 72x - 170 = -2
<=> 6x² + 72x - 168 = 0
<=> x² + 12x - 28 = 0
<=> x² + 12x + 36 = 64
<=> (x+6)² = 64

b
Graph B
c
Graph C
d
Graph D
The graph that best models the exponential function [tex]f(x) = 3(3)^{-x} = \frac{3}{3^x}[/tex] is graph A.
What is an exponential function?An exponential function is modeled by:
[tex]y = ab^x[/tex]
In which:
a is the initial value, that is, the value of y when x = 0.b is the rate of change.In this problem, the function is:
[tex]f(x) = 3(3)^{-x} = \frac{3}{3^x}[/tex]
The initial value is:
[tex]f(0) = \frac{3}{3^0} = 3[/tex]
The x in the exponent is negative, which means that it is a decaying function, hence graph A is correct.

What is the equation of
y=x3
with the given transformations?
vertical stretch by a factor of 3, horizontal shift 4 units to the right, vertical shift 3 units down
Answer:
The parent function is y = x³.
After a vertical stretch by a factor of 3, obtain
y = 3x³
After a horizontal shift 4 unit to the right, obtain
y = 3(x - 4)³
After a vertical shift 3 units down, obtain
y = 3(x - 4)³ - 3
Answer: y = 3(x - 4)³ - 3
y = 3(x - 4)³ - 3 is the equation of y=x³ with the given transformations
What is Graph?Graph is a mathematical representation of a network and it describes the relationship between lines and points.
Graph transformation is the process by which an existing graph, or graphed equation, is modified to produce a variation of the proceeding graph.
The given equation is y=x³
A translation of a graph is its rigid movement, vertically or horizontally.
From given we have,
There is a vertical stretch of 3 units, hence the function is multiplied by 3.
There is a horizontal shift of 4 units to the right, hence x -> x - 4.
There is a vertical shift of 3 units down, hence 3 is subtracted from the function.
The required equation is given by y = 3(x - 4)³ - 3.
Hence y = 3(x - 4)³ - 3 is the equation of y=x³ with the given transformations

Im not exactly sure what to do, could someone help me out?
Answer:
AB = 18 in.
BC = 22 in.
ED = 33 in.
Angle B = not possible
Angle C: not possible
Angle D = 39°
Angle E: not possible
Angle F: not possible
Step-by-step explanation:
Because it is given that ΔABC≅ΔDFE, we can find the corresponding sides and angles and then find all possible missing side and angle measures from the given diagram.
AB corresponds to DF (ΔABC ≅ ΔDFE)
Because DF = 18, then AB must equal 18.
BC corresponds to FE (ΔABC≅ΔDFE)
Because FE = 22, then BC must equal 22.
ED corresponds to CA (ΔABC≅ΔDFE)
Because CA = 33, then ED must equal 33.
Angle D corresponds to angle A (ΔABC≅ΔDFE)
Because angle A = 39°, then angle D must equal 39°.
All other angles cannot be found since they are not given on the corresponding angles of the triangles in the diagram.

Answer:
x = 8
Step-by-step explanation:
Given
- 2(- 3x + 3) + 2x = 58 ← distribute and simplify left side
6x - 6 + 2x = 58
8x - 6 = 58 ( add 6 to both sides )
8x = 64 ( divide both sides by 8 )

What is coordinate?A coordinate system in geometry is a method for determining the precise location of points or other geometrical objects on a manifold, such as Euclidean space, using one or more integers, or coordinates. It matters how the coordinates are arranged.
Sometimes they are recognised by their place in an ordered tuple, and other times they are recognised by a letter, such as "the x-coordinate." In elementary mathematics, the coordinates are assumed to be real numbers. Point A t represents (3, - ).
Therefore, the correct option is option A.
