y=5/3x+9 is the slope intercept form of the equation of line 20x-12y=-108
What is slope intercept form of line?The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.
The given equation is 20x-12y=-108
We need to write this equation in the form of slope intercept form.
To do this we have to isolate the y term
-12y=-108-20x
Now divide both sides by 12 and multiply with minus.
y=9+20/12x
y=9+5/3x
y=5/3x+9 is the required equation.
Hence, y=5/3x+9 is the slope intercept form of the equation of line 20x-12y=-108

find all the zeros of the polynomial function
x^3-2x^2 +5x-10
Answer: x = [tex]\sqrt{5} , -\sqrt{5}[/tex] , and 2
Step-by-step explanation:
in the first two monomials you can factor out x^2, and on the last pair of two monomials you can factor out 5
so, x^2(x-2)+5(x-2)
some rule out there says you can simplify this to
(x^2+5)(x-2)
to find the zeroes, set it equal to zero
(x^2+5)(x-2) = 0
you can split up the pairs of parenthesis to equal 0
(x^2+5) = 0
(x-2)=0
find x for both equation and you end up with [tex]\sqrt{5} , -\sqrt{5} , and 2[/tex]
In April, Francis had math homework 18 out of the 30 days in the month. Which value is equivalent to the fraction of days she had math homework?
Answer:
Step-by-step explanation:
You didn't give the options but let me try help out.
From the question, we are informed that Francis had math homework 18 out of the 30 days in the month.
For us to get the value that is equivalent to the fraction of days she had math homework, we can reduce the fraction to its lowest term. Therefore,
18/30 = 2/5
2/5 is an equivalent fraction.
Three lemon cookies and two fudge cookies have a total of 400 calories. Two lemon cookies and three fudge cookies have a total of 425 calories. How many calories are in each kind of cookie?
Answer:
lemon cremes contain 70 calories. fudge cookies contains 95 calories
Step-by-step explanation:
Let x represent the amount of calories in lemon cremes.
Let y represent the amount of calories in fudge cookies.
Three lemon cremes plus two fudge cookies have 400 calories. This means that
3x + 2y = 400 - - - - - -- - - - -1
Two lemon cremes plus three fudge cookies have 425 calories. This means that
2x + 3y = 425- - - - -- - - - - - 2
Multiplying equation 1 by 2 and equation 2 by 3, it becomes
6x + 4y = 800
6x +9y = 1275
Subtracting,
-5y = - 475
y = - 475/- 5
y = 95
Substituting y = 95 into equation 1, it becomes
3x + 2×95 = 400
3x = 400 - 190 = 210
x = 210/3 = 70
x = 70
A car can travel 476 miles on 14 gallons of gas. Write a proportion relating the distance to the number of gallons. How many miles can the car travel on 17 gallons?
Answer:
578 miles
Step-by-step explanation:
In order to solve this problem, we need to first calculate how many miles the car can travel on a single gallon of gas. To do this we simply divide the 476 miles that the car travelled by the 14 gallons it used to do so.
476 miles / 14 gallons = 34 miles per gallon
Now, we can see that car can travel 34 miles for every gallon of gas it uses. Therefore, in order to calculate the distance, it can travel on 17 gallons, we simply multiply 34 miles by the 17 gallons we will use like so...
34 miles * 17 gallons = 578 miles

What is the equation of the line that is perpendicular to 2x + 4y = 1 and that passes through the point (6,8)?
Answer:
2x - y = 4
Step-by-step explanation:
The base line is 2x + 4y = 1. To obtain a general formula for lines perpendicular to this "standard form" equation, interchange and y and replace the '1' with 'C:'
2y - 4x = C
Since the line in question passes through the point (6, 8), we substitute 8 for y and 6 for x, obtaining:
2(8) - 4(6) = C. Then C = 16 - 24, or = -8.
The desired equation is
2y - 4x = -8, or
4x - 2y = 8, or (after reduction)
2x - y = 4
The opening under a bridge is in the shape of a semielliptical arch and has a span of 82 feet. The height of the arch, at a distance of 9 feet from the center, is 28 feet. Find the height of the arch at its center. Hint: let the center of the horizontal span be (0, 0).
Answer:
28.7 feet
Step-by-step explanation:
The equation of a parabola is in the form:
[tex]\frac{x^2}{a^2}+ \frac{y^2}{b^2}=1\\ \\where\ (\pm a,0)=major\ axis,(0,\pm b)=minor\ axis[/tex]
The bridge can be represented as:
Since the width of the bridge is 82 feet, therefore 2a = 82, a = 41
[tex]\frac{x^2}{41^2} +\frac{y^2}{b^2}=0\\ \\The\ point\ (9,28)\ lie\ on \ the\ ellipse\ hence\ substituting:\\\\\frac{9^2}{41^2} +\frac{28^2}{b^2}=1\\\\0.048+\frac{28^2}{b^2}=1\\\\\frac{28^2}{b^2}=1-0.048=0.952\\\\b^2=824\\\\b=\sqrt{824}\\ \\b=28.7 \\\\[/tex]

Susanna deposits $400 in a savings account with an interest rate of 3% compounded annually. What equation could Susanna use to calculate
how many years it will take for the value of the account to reach $600?
The equation that Susanna could use to calculate how long it would take for the account to reach a value of $600 is 600=400(1.03)^x.
How is future value found?Future value is calculated as:
= Amount x (1 + rate) ^ number of years
If the number of years is to be found and the future value is already known, then the number of years can be x:
600 = 400 x (1 + 3%) ^ number of years
600 = 400(1.03)^x

The range of g(x)= [[x/2]] is:
A. All real numbers
B. All odd integers
C. All integers
D. All negative numbers
E. All even numbers
The requried range of the given greatest integer function is all integers. Option C is correct.
What are functions?Functions are the relationship between sets of values. e g y=f(x), for every value of x there is its exists in a set of y. x is the independent variable while Y is the dependent variable.
Given expression g(x)= [[x/2]],
Since the given expression is the greatest integer function so the range of the function will be all integers as given as,
For example,
x = 3
g(x) = [[x / 2]]
g(3) = [[3 / 2]]
= [1.5]
= 2 [since for greatest integer function [x] = x + 1 or = x]
Thus, the requried range of the given greatest integer function is all integers. Option C is correct.
