Answer:
j = 0 or j = 30
Step-by-step explanation:
j² - 30j = 0
Factorise j out of both terms on the left side.
j (j-30) = 0
Apply zero product rule.
j = 0 or j-30 = 0
Find the value of j.
j = 0 or j = 30

One gallon of gasoline in Buffalo, New York costs $2.29. In Toronto, Canada, one liter of gasoline costs $0.91. There are 3.8 liters in one gallon.
Answer the questions below.
1. How much does one gallon of gas cost in Toronto? Round your answer to the nearest cent.
2. Is the cost of gas greater in Buffalo or in Toronto?
3. How much greater?
Answer:
The cost of one gallon of gas in Toronto, Canada is $3.458.
Solution:
Given, One gallon of gasoline in buffalo, New York costs $2.29.
In Toronto, Canada, one liter of gas costs $0.91.
There are 3.8 liters in one gallon.
We have to find how much does one gallon of gas cost in Toronto?
Now, cost of one gallon of gas in Toronto = cost of one litre of gas in Toronto x 3.8 liters for 1 gallon.
Cost of one gallon of gas = 0.91 x 3.8 = 3.458
Hence, the cost of one gallon of gas in Toronto, Canada is $3.458.

Loren is running in a long distance race. She is able to keep a steady pace of 10 feet per second.
Answer:
a or c Im not sure
Step-by-step explanation:
I think b though
The line which represents the speed as 10 feet per second is line B thus none of the given options are correct.
What is a graph?A graph is a diametrical representation of any function between the dependent and independent variables.
For example y = x² form a parabola now by looking at only the graph we can predict that it has only a positive value irrespective of the interval of x.
As per the given,
Loren is running at speed of 10 feet per second.
Speed = distance covered/time taken
10 = distance covered/time taken
In line B, the ratio of distance covered/time taken is 10.
Thus, line B will be correct.
Hence "The line which represents the speed as 10 feet per second is line B thus none of the given options are correct".

The cost of the hiking trip this year is 2/3of the cost of last year's trip. This year's trip cost $32
1. Write an equation that represents the cost of last years trip.
2.What was the cost of last year's trip
Answer:
The equation is ( 32/2 ) × 3 = 48.
Step-by-step explanation:
In order to find the answer, we must find one third of last years trip. To do this, we can simply divide the cost of this year's trip by two, 32/2=16.
Now if we multiply this years trip by 3, 16×3=48, we can see that the total cost of last years trip was $48.
If we'd like to turn this into a equation, it looks like this:
( 32/2 ) × 3 = 48.
What is the solution to the system of equations graphed below?

Solve for x, 2-x= -6-4x
a . -2/3
b.-2/5
c-8/3
d.-8/5
Answer:
-8/3
Step-by-step explanation:
2 - x = - 6 - 4x <-- Add 4x to the left side
2 + 3x = - 6 <-- Subtract 2 from the left side
3x = -8 <-- Divide 3 on both sides
x = -8/3
Answer:
x = -8/3
Step-by-step explanation:
Consolidate x terms on the right side:
2-x= -6-4x becomes 2-x + x = -6-4x + x, which in turn becomes:
2 = -6 - 3x, or 3x = -8. Then, dividing both sides by 3, we get x = -8/3
Which of the following inequalities is true?
A) -4 <-5
B) -3<-2
C) 0 <-4
D) 1 < -2
Answer:
B) -3 < -2
Step-by-step explanation:
The smaller the negative number, the more "positive" it is. Also, -2 is more than -3 because it is closer to 0.
What is the slope of the line that passes
through the points (3, 2) and (-1,-4)? Write
your answer as a fraction in simplest form
Answer:
Step-by-step explanation:
Slope = (Difference of y-coordinates)/(difference of x-coordinates)
= (-4 - 2)/(-1 - 3)
= (-6)/(-4)

find the equation that represents the proportional relationship in this graph
Answer:
y = 4/5x
Step-by-step explanation:
Points on the graph: (5, 4) and (0, 0)
Slope:
m=(y2-y1)/(x2-x1)
m=(0-4)/(0-5)
m=(-4)/(-5)
m= 4/5
Slope-intercept:
y - y1 = m(x - x1)
y - 4 = 4/5(x - 5)
y - 4 = 4/5x - 4
y = 4/5x

7. Find the slope of the line.
slope = rise/run
= ?/?, or ?
the slope is ___
Answer:
5
Step-by-step explanation:
You can find the slope with rise over run. Rise means up and run means moving right or left. In this case rise is 10 and run is 2. This means the fraction will look like 10/2. Simplify this to get 5 and that is your answer.
Hope this helps.
Answer:
slope 10/2=5
Step-by-step explanation:

What is the equation of the trend line in the scatter plot?
Someone pls help I will pay if you get it right
Given:
The graph of a trend line.
To find:
The equation of the trend line.
Solution:
From the given graph it is clear that the trend line passes through the points (0,4) and (9,7). So, the equation of the trend line is:
[tex]y-y_1=\dfrac{y_2-y_1}{x_2-x_1}(x-x_1)[/tex]
[tex]y-4=\dfrac{7-4}{9-0}(x-0)[/tex]
[tex]y-4=\dfrac{3}{9}(x)[/tex]
[tex]y=\dfrac{1}{3}x+4[/tex]
Therefore, the equation of the trend line is [tex]y=\dfrac{1}{3}x+4[/tex].
