Hi there!
[tex]\large\boxed{0, -\frac{9}{4} }[/tex]
2x - 4y = 9
Begin by isolating the y variable by moving 2x to the right-hand side of the equation. (Subtract 2x from both sides):
2x - 2x - 4y = 9 - 2x
-4y = 9 - 2x
Further isolate by dividing both sides by -4:
-4y / (-4) = (9 - 2x) / (-4)
y = -9/4 - 2x/(-4)
Simplify further:
y = -9/4 + 1/2x
y = 1/2x - 9/4
The "b" value is the y-intercept, therefore:
x = 0 at y = -9/4
Answer:
[tex]\huge\boxed{(0, \frac{-9}{4} )}[/tex]
Step-by-step explanation:
2x - 4y = 9
To find the y-intercept, set the x value in the equation to 0.
Rewrite
2(0) - 4y = 9
Simplify
-4y = 9
Multiply both sides of the equation by -1
4y = 9
Divide both sides of the equation by 4
y = -9/4
y = -4.5
Now that we know the y intercept, we can find the coordinate.
(x, y)
Substitute
(0, [tex]\frac{-9}{4}[/tex])

Sabrina is going to rent a bicycle while in vacation. There are two rental companies she can choose from. The first company charged $10 plus a rate of $2 per hour until the bicycle is returned. The second company’s rental charges can be represented by the equation c=3h+6 where c represents the rental cost and h represents the number of hours the bicycle is rented. If Sabrina plants to bicycle for 3 hours, what is the least amount she could pay in rental fees?
Answer:
9
Step-by-step explanation:
Ever since Renata moved to her new home, she's been keeping track of the height of the tree outside her window.
H
HH represents the height of the tree (in centimeters),
t
tt years since Renata moved in.
H
=
210
+
33
t
H=210+33tH, equals, 210, plus, 33, t
Answer:
The tree's height when Renata moved in was
210 centimeters.
Step-by-step explanation:
When Renata first moved in, the number of years since she moved in,
t, was 0.
We can calculate the height of the tree at that time:
h=210+33t
h=210+33(0)
Then you distribute 33 into 0 (Multiply)
h=210+0
h=210
Therefore the trees Height (h) when Renata moved in was 210cm.

In the accompanying diagram of a parallelogram
ABCD ,DC= 5x-18, BC=3x-6, AB=2x+12 find measure BC. Please help
Answer:
BC = 39
Step-by-step explanation:
Given:
DC = 5x - 18,
BC = 3x - 6,
AB = 2x + 12
Opposite sides of a parallelogram are equal.
Therefore:
AB = DC
2x + 12 = 5x - 18
Collect like terms
12 + 18 = 5x - 3x
30 = 2x
Divide both sides by 2
15 = x
x = 15
BC = 3x - 6
Plug in the value of x
BC = 3(15) - 6 = 45 - 6
BC = 39
What unit is used to measure the density of a solid??
Answer:
Grams per cubic meter or g/cm3
Step-by-step explanation:
The answers vary, but they have the same format which is
density = mass/volume
For instance, if the mass is in grams and the volume is in cubic centimeters, then the density would be in grams/cm^3, where "cm^3" is the abbreviation of "cubic centimeters". We can read "grams/cm^3" out as "grams per cubic centimeter"

Write the equation of the line that is parallel to the y-axis and passes through the point (-7 , 2).
Answer:
x=-7
Step-by-step explanation:
since it is parallel to the y-axis, it doesn't have a slope and the equation will look like x=_. x=-7 because when it is parallel to the y-axis, it will always have the same x-value, but the y-value will continue to increase or decrease

Solve the system of equations below:
y = 3x - 5
y = -2x + 10
Answer: x=3
y=4
Step-by-step explanation:
since both equations equal y then you can just make them equal
so 3x-5=-2x+10
3x=-2x+15
5x=15
x=3
y=3(3)-5
y=9-5
y=4

There are 4,050 newspapers to be delivered in a certain area of town. If 18 newspaper carriers are all delivering the same number of papers, how many will each deliver?
Given :
There are 4,050 newspapers to be delivered in a certain area of town.
To Find :
If 18 newspaper carriers are all delivering the same number of papers, how many will each deliver.
Solution :
Let, total number of deliver are n.
Total newspaper, T = 4050 .
Number of news carriers, N = 18 .
So,
[tex]n = \dfrac{T}{N}\\\\n = \dfrac{4050}{18}\\\\n = 225[/tex]
Therefore, each deliver will carry 225 newspapers.
Hence, this is the required solution.

When finding the slope of the trend line, what does the slope mean about the data of the scatterplot? Explain.
Answer:
So the slope on a scatterplot is almost always an estimate, so its not exact. It is just an estimate on where it might go and what might happen t data in the future.
Answer:
The slope of the trend line is the rate of change of the data. It is the ratio of the change of the dependent variable to the rate of change of the independent variable. Slope represents the value of the correlation.
