Answer: y + 7 = 3/4(x - 0)
Step-by-step explanation:
This is point slope form: y - y1 = m(x - x1)
Plug in a coordinate for y1 and x1, but leave y and x alone. M is the slope.
So, plug everything in (for this specific problem, don't simplify after plugging the values in)
y - - 7 = 3/4(x - 0)
y + 7 = 3/4(x - 0)
Find the equation of the linear function represented by the table below in slope intercept form

The dot plot showed the number of flowers on a rosebush: 18, 18, 18, 18, 20, 20, 22, 23 The number 19 is used to summarize the data. What does this number measure?
Answer:
19 measures the median
Step-by-step explanation:
The dot plot is not shown, but the question can still be answered.
We have:
[tex]Samples: 18, 18, 18, 18, 20, 20, 22, 23[/tex]
[tex]n = 8[/tex]
Calculate the median position using:
[tex]Median = \frac{n + 1}{2}th[/tex]
[tex]Median = \frac{8 + 1}{2}th[/tex]
[tex]Median = \frac{9}{2}th[/tex]
[tex]Median = 4.5th[/tex]
4.5th means the median is the mean of the 4th and 5th item.
We have:
[tex]4th = 18[/tex]
[tex]5th = 20[/tex]
So:
[tex]Median = \frac{18 + 20}{2}[/tex]
[tex]Median = \frac{38}{2}[/tex]
[tex]Median = 19[/tex]

[tex]r=\frac{7±3\sqrt{5} }{2}[/tex]
Ignore the A before the ±. It wouldn't let me type it correctly.
Step-by-step explanation:
2r² + 7r - 1 = 3r²
2r² + 7r - 1 - 3r² = 0
- r² + 7r - 1 = 0
- (r² - 7r + 1) = 0
- (r² - 7r + 1) ÷ - 1 = 0 ÷ - 1
r² - 7r + 1 = 0
[tex]r=\frac{-b±\sqrt{b^{2}-4ac } }{2a}[/tex]
Ignore the A before the ±. It wouldn't let me type it correctly.
r² - 7r + 1 = 0
a = 1
b = - 7
c = 1
[tex]r=\frac{-(-7)±\sqrt{(-7)^{2}-4((1)(1)) } }{2(1)}[/tex]
[tex]r=\frac{-(-7)±\sqrt{49-4((1)(1)) } }{2(1)}[/tex]
[tex]r=\frac{-(-7)±\sqrt{49-4 } }{2(1)}[/tex]
[tex]r=\frac{-(-7)±\sqrt{45 } }{2(1)}[/tex]
[tex]r=\frac{-(-7)±\sqrt{(3)(3)(5) } }{2(1)}[/tex]
[tex]r=\frac{7±(\sqrt{3 } )(\sqrt{3})(\sqrt{5}) }{2(1)}[/tex]
[tex]r=\frac{7±3\sqrt{5} }{2}[/tex]
Two separate equations
[tex]r=\frac{7+3\sqrt{5} }{2}[/tex]
[tex]r=\frac{7-3\sqrt{5} }{2}[/tex]

rhombus wxyz with vertices w(1 0) x(4,-1) y(5,-4) and z(2,-3)
Answer:
W 2,3
X 5,3
Y 1,2
Z 8,4
Step-by-step explanation:
The coordinates of the Rhombus after the dilation is W' ( 3 , 0 ) , X' ( 12 , -3 ) , Y' ( 15 , -12 ) and Z' ( 6 , -9 )
What is Dilation?Resizing an item uses a transition called Dilation. Dilation is used to enlarge or contract the items. The result of this transformation is an image with the same shape as the original. However, there is a variation in the shape's size. Dilation transformations ensure that the shape will stay the same and that corresponding angles will be congruent
The result of dilation is that the shapes and boundaries of objects in the input image are expanded or thickened. It is often used in conjunction with other morphological operations such as erosion, opening, and closing to manipulate and enhance images.
Given data ,
Let the coordinates of the rhombus be represented as WXYZ
where W' ( 1 , 0 ) , X ( 4 , -1 ) , Y ( 5 , -4 ) and Z ( 2 , -3 )
Now , the dilation scale factor is k = 3 centered at origin
So , result of this transformation is an image with the same shape as the original
The coordinates of the dilated figure is W'X'Y'Z'
where W' ( 3 , 0 ) , X' ( 12 , -3 ) , Y' ( 15 , -12 ) and Z' ( 6 , -9 )
Hence , the dilation is solved

-12 -12
6n = -107
Divide by 6 on both sides:
N = -17.8333333333 around -17
Step-by-step explanation:
We need to isolate the variable meaning keeping the variable by itself on the left side. In order to do that we must get rid of any constants or co-efficients.
Answer:
Hey mate......
Step-by-step explanation:
This is ur answer.....
6n + 12 = -60 -35= 6n + 12 = -95
= 6n = -95 - 12
= 6n = -107
= n = -107 / 6

A box contains 4 marbles: 1 blue, 1 yellow, 1 green, and 1 white. A marble is randomly drawn from the box and a number cube, labeled 1 through 6, is tossed. What is the probability of getting a yellow marble and an odd number? Express as a fraction in simplest form.
Answer:
The answer is 1/8
Step-by-step explanation:
There are 4 marbles in the box and one of them is a yellow marble. The odds of getting a yellow marble fr the box is 1/4.
A number cube labeled 1 through 6 has 6 numbers, which are 1, 2, 3, 4, 5 and 6. The odd numbers in the cube are 1, 3 and 5. The probability of getting an odd number from the cube is 3/6, which is simplified to 1/2.
To find the probability of both cases occurring, both fractions should be multiplied.
1/4 * 1/2 = 1/8

Answer:
Y = 9
Step-by-step explanation:
Answer:
y = 9
Step-by-step explanation:
2 + 4 ( y - 1 ) = 2y + 16
step 1 distribute the 4
4 * y = 4y
4 * -1 = -4
we now have 2 + 4y - 4 = 2y + 16
step 2 combine like terms
2 - 4 = - 2
we now have - 2 + 4y = 2y + 16
step 3 add 2 to each side
-2 + 2 cancels out
16 + 2 = 18
we now have 4y = 2y + 18
step 4 subtract 2y from each side
2y - 2y cancels out
4y - 2y = 2y
we now have 2y = 18
step 5 divide each side by 2
2y / 2 = y
18 / 2 = 9
we're left with y = 9

What is Bio-Fuel?Bio-fuel is a type of fuel that is created quickly from biomass, as opposed to the lengthy natural processes that result in the development of fossil fuels like oil. Plants may be used to make biofuel, as well as home, commercial, and agricultural biowaste.
Given data ,
Any fuel that is made from biomass, or plant, algae, or animal waste, is referred to as a biofuel. Unlike to fossil fuels like petroleum, coal, and natural gas, biofuel is seen as a source of renewable energy due to the ease with which such feedstock material may be supplied.
In light of rising petroleum prices and growing concern about the role fossil fuels play in global warming, biofuel is frequently promoted as a convenient and ecologically friendly substitute for petroleum and other fossil fuels.

The value of x and y is 16 and 20.
The calculation is as follows:7x + 4+ 5x - 16 = 180
12x = 180 + 12
12x = 192
x = 16
Now
6y - 4 = 116

Claire completed the steps to solve the system of equations. 4 x minus 2 y = 4. 3 x + 3 y = 21. Step 1 12 x minus 6 y = 12. 6 x + 6 y = 42. Step 2 18 x = 54. Step 3 x = 3. Step 4 4 (3) minus 2 y = 4. 12 minus 2 y = 4. 2 y = negative 8. Y = negative 4. Step 5 Solution is (3, negative 4). Is Claire's solution to the system of equations correct? Explain why or why not.
Answer:
Claire should have gotten –2y = –8 instead of 2y = –8 in step 4.
Step-by-step explanation:
Following the steps taken :
4x - 2y = 4 - - - (1)
3x + 3y = 21 - - - (2)
Multiply (1) by 3 and (2) by 2
12x - 6y = 12 - - - (3)
6x + 6y = 42 - - - (4)
Add (3) and (4)
18x = 54
x = 54/18
x = 3
Put x = 3 in (1)
4(3) - 2y = 4
12 - 2y = 4
-2y = 4 - 12
-2y = - 8 (this is where the mistake lies)
It shouldn't be 2y = - 8 as stated

Step-by-step explanation:
The amount of lawns that he can mow in 10 hours is; A: five Lawns
What is the amount of work to be done?
We are told that it takes a time of 4 hours to mow 2 lawns. Thus, amount of lawn he can mow in 1 hour = 2/4 = 0.5 lawn per hour
Thus, amount of lawn he can mow in 10 hours = 0.5 * 10 = 5 lawns
In conclusion he will mow 5 lawns in 10 hours.
