Find the equation of a line that passes through points (9,3) and (-6,5)?
Answer:
Y= X - 31.5
Step-by-step explanation:
find the gradient then the equation
Answer:
y-3 = -2/15 (x-9)
Step-by-step explanation:
First, we should find the gradient, m, which is [tex]\frac{rise (change.in.the.y.value)}{run (change.in.the.x.value)}[/tex]
This is [tex]\frac{3-5}{9-(-6)} =-\frac{2}{15}[/tex]
A linear (straight) line has a general equation y=mx+c
y = [tex]-\frac{2}{15\\}[/tex]x+c
We can rewrite the equation into the general form:
y-y1 = m(x-x1)
where y1 is the value of a y coordinate and x1 is the x value of the coordinate that the y1 value was taken from.
This stems from the idea that 0 = 0.
To make that equation true, we can make both sides equal to 0.
To do that, y - y1 has to be - and x-x1 has to be zero. m can be ignored as anything multiplied by 0 is 0.
Up until here, y1 and x1 are arbitrary constants. They are values that we have to find. However, we don't actually. We have coordinates that the x and y will equal to. (9,3)
Because 9 - 9 = 0 and 3 - 3 = 0, we can state that the value of y1 is 3 and x1 is 9.
Hence, the equation is y-3 = -2/15 (x-9)
You can rearrange the equation to make it into the form y = mx + c, but this is usually not necessary.
I hope this helped.

What is the volume of this cone?
Answer:
[tex]V=209\ cm^3[/tex]
Step-by-step explanation:
The height of this cone, h = 8 cm
The radius of this cone, r = 5 cm
We need to find the volume of this cone. The formula for the volume of a cone is given by :
[tex]V=\dfrac{1}{3}\pi r^2 h[/tex]
Put all the values,
[tex]V=\dfrac{1}{3}\times 3.14\times 5^2 \times 8\\\\=209.33\approx 209\ cm^3[/tex]
So, the volume of this cone is equal to [tex]209\ cm^3[/tex].

HELLPPPPPPPP PLS. What is the volume of the rectangular prism?
Type the answer in the boxes below.
NI
cm
Answer:
3.75 cm³
Step-by-step explanation:
Each cube has equal sides of 1/2 cm
Length of the rectangular prism = 1/2 cm * 5
= 2.5 cm
Width of the rectangular prism = 1/2 cm * 2
= 1 cm
Height of the rectangular prism = 1/2 cm × 3
= 1.5 cm
Volume of the rectangular prism = length × width × height
= 2.5 cm * 1 cm * 1.5 cm
= 3.75 cm³
Volume of the rectangular prism = 3.75 cm³

Find the 13th term of the arithmetic sequence -3x+7, -5x+3, -7x-1, ...
Answer:
a₁₃ = - 27x - 41
Step-by-step explanation:
The nth term of an arithmetic sequence is
[tex]a_{n}[/tex] = a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = - 3x + 7
d = a₂ - a₁ = - 5x + 3 - (- 3x + 7)
= - 5x + 3 + 3x - 7
= - 2x - 4
Then
a₁₃ = - 3x + 7 + 12(- 2x - 4)
= - 3x + 7 - 24x - 48
= - 27x - 41

Answer:
PX = 2√11
Step-by-step explanation:
here's your solution
==> ZX = 12 m
==> ZP = 10 m
==> by using Pythagoras theorem
==> PX^2 = ZX^2 - ZP^2
==> PX^2 = 12^2 - 10^2
==> PX^2 = 144 - 100
==> PX^2 = 44
==> PX = √44
==> PX = 2√11

70 - 2^3x = 35
Answer:
x=4.375
Step-by-step explanation:
Answer:
x= 1.71
Step-by-step explanation:
We need to isolate x in the equation, first subtract 70 from the left side, so the equation is, -[tex]2^{3x\\}[/tex]=-35. There is a negative sign in both equations so we cancel them out so our equation is [tex]2^{3x\\}[/tex]=35. Now we use log, so our equation now looks like {log(35)/log(2)}/3=x. When we do it out we get that x=1.70976, and when rounded we get, x-1.71.

Write the repeating decimal as a mixed number.
Answer:
1 1/30
Explanation:
we know that 0.3 (recurring) is equivalent to ⅓. thus, we can find 0.03 (recurring) by adding an extra decimal behind the denominator to get 1/30.
accounting for the 1, we can now get 1 1/30.
