Identify the slope and y-intercept of the graph of the equation. y = 5/3 x -2
Answer:
Slope: [tex]\frac{5}{3}[/tex]
Y-intercept: -2
Step-by-step explanation:
Conveniently, this equation is already in slope-intercept form.
The slope is always the constant of proportionality, which we multiply x by.
Therefore the slope is [tex]\frac{5}{3}[/tex].
The y-intercept is always the constant that comes after the x term, which is -2.
So the y-intercept is -2.
Hope this helped!
Answer:
Slope: 5/3
Y-intercept: -2
Step-by-step explanation:
Since your equation is already in slope intercept form, it makes it easier for you to identify the slope and y-intercept.
In your equation ([tex]y = \frac{5}{3} x -2[/tex]) the coefficient of 5/3 is your slope and your constant of -2 is your y-intercept.

The admission fee at a carnival fair is $4.50 for children
and $8.00 for adults. One day, 2200 people attended the fair
and $5050 was collected. How many children and how many
adults attended?
Lets say:
c= number of children
a= number of adults
Answer:
Adult=1,385.71
Children=814.29
Approximately
Adult=1386
Children=814
Step-by-step explanation:
c= number of children
a= number of adults
Admission fee for children=$4.50
Admission fee for adults=$8.00
Total attendees=2200
Total amount realized=$5050
We need two equations to solve the two unknowns
c + a=2200 (1)
4.50c + 8.00a=5,050 (2)
From (1)
c + a=2200
c=2200 - a
Substitute c=2200 - a into (2)
4.50c + 8.00a=5,050
4.50(2200 - a) + 8.00a=5050
9900 - 4.50a +8.00a=5050
Collect like terms
9900-5050= -4.50a+8.00a
4,850=3.5a
Divide both sides by 3.5
1,385.71=a
Substitute a=1,385,71 into (1)
c + a=2200
c+1385.71=2200
c=2200-1385.71
=814.29
c=814.29

Two radio stations are playing this week's #1 hit song. One radio station plays the song every 18 minutes. The other radio station plays the song every 24 minutes. Both stations play the song at 3pm. How many minutes will pass before they play the same song again.
Answer:
72 minutes until they play again
Step-by-step explanation:
18+18+18+18=72
24+24+24=72
Answer: 72 minutes
======================================================
Explanation:
The GCF of 18 and 24 is 6, since this is the largest factor shared between the two numbers
18 = 6*324 = 6*4To find the LCM, we'll involve the GCF. The LCM of two numbers x and y is found by multiplying them, and then dividing over the GCF of them.
LCM of x and y = (x*y)/(GCF of x and y)
LCM of 18 and 24 = (18*24)/6
LCM of 18 and 24 = 432/6
LCM of 18 and 24 = 72
-----------
To help confirm this, we can list out the multiples of each
multiples of 18 are: 18, 36, 54, 72, 90, ...multiples of 24 are: 24, 48, 72, 96, ...We see that 72 is the lowest common multiple. This is the final answer because each station will play the same song 72 minutes apart.
The stations play the same song at 3 PM. Then 72 minutes later (4:12 PM), the same song is played again on both stations at the same time. Then at 5:24 PM, another 72 minute gap, is when the same song is played again at the same time. And so on.
----------
Side note: 72 minutes = 60 min + 12 min = 1 hr, 12 min

Jerome currently has an account balance of $1,859.55. His initial deposit on the account was $825 and it earned 5.7% simple interest. How long has Jerome held the
account?
Answer:
22 years
Step-by-step explanation:
Well we know the formula for simple interest is
I = PRT
I = interest earned
P = initial balance
R = rate
T = time
We want to solve for time here....so rearrange for T
T= I/(PR )
We have
P = 825
R = .057
And I = current balance - initial balance = 1859.55 - 825 = 1034.55
So plugging all those in we have
T = 1034.55/(825×.057 )
T = 1034.55/47.025
T = 22
It was held for 22 years.

Step-by-step explanation:
The equation of the parabola is y = (x - 1)² - 4. Then the vertex of the parabola is at (1, -4) and the parabola passes through (0, -1) and (0, 3).
What is the parabola?It is the locus of a point that moves so that it is always the same distance from a non-movable point and a given line. The non-movable point is called focus and the non-movable line is called the directrix.
The equation is given below.
y = (x + 1)(x - 3)
We know that the equation is a parabolic equation.
And the value of y at -1 and 3 is zero.
The equation can be written as
y = x² - 2x -3
y = (x - 1)² - 4
And the vertex of the parabola is at (1, -4).
The graph is shown below.

D. 127
Answer:
D. 127°
Step-by-step explanation:
The exterior angle (x) is the sum of the remote interior angles (y, z).
Setupx = y +z
(197 -5n) = (6n +22) +(n +7) . . . . . substituting the given expressions
SolutionEliminating parentheses and collecting terms, we have ...
197 -5n = 7n +29
168 = 12n . . . . . . . . . add 5n-29
14 = n . . . . . . . . . . divide by 12

Answer:
$86.81
Step-by-step explanation:
Using the given formula, we want to compute A for ...
P = 4750
r = 0.2279
n = 365 . . . . . assuming "exact" interest
t = 1 or 30
For 1 day late:
A = 4750(1 +0.2279/365)^(365·(1/365)) = 4752.97
For 30 days late:
A = 4750(1 +0.2279/365)^(365·(30/365)) = 4839.78
The difference in these payment amounts is ...
$4839.78 -4752.97 = $86.81
You would save $86.81 in interest charges by paying only 1 day late.

There are four points on a line: A, B, C and D, so that AB=1, BC=2, CD=4. Find all the possibilities of the length of segment AD.
Answer:
{1, 3, 5, 7}
Step-by-step explanation:
There are four possibilities:
AD = AB -BC -CD = 1 -2 -4 = -5
AD = AB +BC -CD = 1 +2 -4 = -1
AD = AB -BC +CD = 1 -2 +4 = 3
AD = AB +BC +CD = 1 +2 +4 = 7
Possible lengths of AD are 1, 3, 5, 7.
__
The negative sign means the segment is added toward the left instead of toward the right. A final negative value means D is left of A, instead of to the right.

Find the m∠RLU. A. 20 B. 42 C. 84 D. 10
Answer:
b is the correct answer. p is 10
The value of m∠RLU = 10.
How to estimate the value of m∠RLU?Given: (5p - 8) and (2p + 22)
Simplifying both of the equation, then we get
5p - 8 = 2p + 22
Add 8 to both sides of the equation, then we get
5p - 8 + 8 = 2p + 22 + 8
simplify
5p = 2p + 30
substract 2p from both sides of the equation
5p - 2p = 2p + 30 - 2p
3p = 30
p = 30/3
p = 10.
m∠RLU = 10
Therefore, the correct answer is option D. 10.

If g (x) is the inverse of f (x) and f (x) = 4 x + 12, what is g (x)
g (x) = 12 x + 4
g (x) = one-fourth x minus 12
g (x) = x minus 3
g (x) = one-fourth x minus
Answer:
[tex]g(x) = \frac{1}{4} x - 3[/tex]Step-by-step explanation:
Since g(x) is the inverse of f (x) to find g(x) must first find f-¹(x)
To find f-¹(x) equate f(x) to y
That's
f(x) = y
y = 4x + 12
Next interchange the terms x becomes y and y becomes x
That's
x = 4y + 12
Next make y the subject
4y = x - 12
Divide both sides by 4
[tex]y = \frac{1}{4} x - 3[/tex]Therefore
[tex]g(x) = \frac{1}{4} x - 3[/tex]Hope this helps you
Which scatterplot shows the strongest negative linear association? On a graph, points are grouped closely together and increase. On a graph, points are grouped closely together to form a line and increase. On a graph, points are grouped closely together and decrease. On a graph, points are grouped closely together to form a line and decrease.
On a graph, points are grouped closely together to form a line and decrease.
====================================
Explanation:
Negative association is where the points decrease as you move from left to right. In other words, you move downhill as you move from left to right. There could be random upward bumps here and there, but overall the general trend is down.
Linear association is when the points are close to the same straight line, known as the regression line.
When points have strong negative linear association, we combine the two ideas mentioned above. The points are close to the same straight line and this line has a negative slope. The correlation coefficient r is close to r = -1.
Choice C is a close answer, but choice D is the better answer due to the "to form a line". If all points are on the same straight line, then r = -1 exactly and we have the strongest possible negative correlation.
The strongest negative linear association is depicted by the graph where points are grouped closely together to form a line and decrease.
Linear associations are deduced from a graph when the points are grouped closely together to form a line. Then we have a strong linear association. Negative association are deduced from a graph when the slope of the line decreasesTherefore, a graph with closely grouped points which forms a line and decreases infers a strong negative linear association.
