Answer:
a)30-100/1000 • 120
Step-by-step explanation:
Given:
Remaining volume of fuel in a cars tank = I - E • D
where,
I = initial volume of fuel
E = fuel efficiency
D = distance traveled.
Carson
I = 30
E = 100
D = 120
Estimated volume of fuel in Carson's tank = I - E • D
= 30 - 100/1000 * 120
a)30-100/1000 • 120
Answer:
A (30-(100/1000)x120)
Step-by-step explanation:
I is a volume quantity, D is a distance quantity, and E is a rate measured as volume/distance.
So ExD gives us volume quantity.
Distance units are consistent (kilometers) but the volume units of E are inconsistent with those of I and the desired answer.
Let's convert E to liters per kilometer. We will use the fact that there are 1000 cubic centimeters per liter.
You get: 30 liter - 100/1000 liters/kilometer x 120 kilometers
In conclusion, this is the calculation that will give us the estimated volume of fuel that remains in Carson's tank by the end of the drive, in liters:
30-100/1000x120.
Hope this helps!

Suppose that y varies directly with x
and y = 5 when x = 6. What is y
when x= 5?
Be sure to simplify your answer.
у
Answer:
i need free points, thank you
Step-by-step explanation:
Step-by-step explanation:
y varies x
y=kx
when y=5;x=6
5=6k
5/6=k
Now, when y=?;x=5
y=5\6(5)
y=25\6
y=4.17
Through (-2,-4), slope = -1/7
Answer:
y = -1/7x -6/7
Step-by-step explanation:
y = mx +b
m = -1/7
y = -1/7x +b
-4 = -1/7(-2)
-4 = -2/7
-4 + -2/7 = b
b = -6/7
y = -1/7x -6/7
HELP PLEASE AND THANK YOU!!!!
Answer:
the answer is -2.1
Step-by-step explanation:
you get this by putting that -4 where the x is and solving so it would look something like this
1.7x+4.7 for x= -4
1.7(-4) + 4.7
-6.8 + 4.7
-2.1

what is the equation of the line that passes through (5,3) and is parallel to 5x+ y=8
Answer:
5x+y=28
..................................
Answer:
Step-by-step explanation:
y = -5x + 8
y - 3 = -5(x - 5)
y - 3 = -5x + 25

The figures below show sketches of Earl's and Dylan's flower gardens. If the perimeter of each of their gardens is the same, what is the length and width of Earl's garden?
Answer:
[tex] length = 12 ft [/tex]
[tex] width = 8 ft [/tex]
Step-by-step explanation:
Earl's garden:
[tex] length = (x + 6) ft [/tex]
[tex] width = (x + 2) ft [/tex]
[tex] perimeter = 2(length) + 2(width) [/tex]
[tex] perimeter = 2(x + 6) + 2(x + 2) [/tex]
[tex] perimeter = 2x + 12 + 2x + 4 = (4x + 16) ft [/tex]
Dylan's garden:
[tex] length = (2x - 2) ft [/tex]
[tex] width = (x + 4) ft [/tex]
[tex] perimeter = 2(length) + 2(width) [/tex]
[tex] perimeter = 2(2x - 2) + 2(x + 4) [/tex]
[tex] perimeter = 4x - 4 + 2x + 8 = (6x + 4) ft [/tex]
Generate an equation to solve for the value of x.
Since the perimeters of both gardens are the same, therefore:
[tex] 6x + 4 = 4x + 16 [/tex]
Collect like terms
[tex] 6x - 4x = - 4 + 16 [/tex]
[tex] 2x = 12 [/tex]
Divide both sides by 2
[tex] x = 6 [/tex]
Earl's garden:
[tex] length = (x + 6) ft [/tex]
Plug in the value of x
[tex] length = 6 + 6 = 12 ft [/tex]
[tex] width = (x + 2) ft = 6 + 2 = 8 ft [/tex]
Answer:
l: 12ft
w: 8ft

The function rule T–4, 6(x, y) could be used to describe which translation?
T–4, 6(x, y) could be used to describe a horizontal translation to the right by 4 units, and a vertical translation up by 6 units
How to describe the translation?The rule is given as:
T–4, 6(x, y)
This can be rewritten as:
(x - 4, y + 6)
The above means that:
A horizontal translation to the right by 4 units, and a vertical translation up by 6 units

What is the value of the expression below when z = • 3?
622 + 2z + 10
Answer:
632.6
Step-by-step explanation:
Z = .3 right? It looks weird on my screen
Anyway, if z is .3 than this is how to solve
First you plug in 0.3 where the z would go, making the expression 622 + 2(0.3) + 10. Then you solve! (below)
622 + 2(0.3) + 10.
622 + 0.6 + 10.
622 + 10 + 0.6
632 + 0.6
632.6

Select the table that shows a frequency distribution.
Answer:
Step-by-step explanation:
hello I need help with graphing my functions it's y = 2x + 3 but I need to graph it
The variable x is a placeholder for a number
Let's say we replace x with 0
y = 2x+3
y = 2(0)+3
y = 0+3
y = 3
This means x = 0 and y = 3 pair up together. In short, the point (0,3) is on the line.
--------------
Let's repeat for x = 1
y = 2x+3
y = 2(1)+3 ... replace x with 1
y = 2+3
y = 5
So (1,5) is another point on the line
---------------
We can keep this process going to generate as many points as we want. But to graph a linear equation like this, we only need two points at minimum.
Graph both (0,3) and (1,5). Then draw a straight line through them both. The graph is shown below.

Consider the following Expression.
-3(y+3)=2y+3
What Is the value of y?
Answer:
y= -12/5
Decimal form: -2.4
Step-by-step explanation:
Distribute the negative 3 on the left side
-3y-9=2y+3
Add 3y to both sides
-9=5y+3
Subtract 3 from both sides
-12=5y
Divide by 5 on both sides
y=-12/5 or -2.4
