Answer:
y = 2/5x - 5
Step-by-step explanation:
(-10,-9) and (10,-1)
Slope: (-1 - - 9) / ( 10 - - 10)
Slope = 8/20 = 2/5
b = -9 - (2/5(10)
b = -5
The equation of the line that passes through the point (−10,−9) and (10,-1) is; y = 2/5x - 5
What is the Point-slope form?The equation of the straight line has its slope and given point.
If we have a non-vertical line that passes through any point(x1, y1) and has a gradient m. then general point (x, y) must satisfy the equation
y-y₁ = m(x-x₁)
Where x₁ - x coordinate, y₁ - y coordinate, m - slope
Slope: (-1 - - 9) / ( 10 - - 10)
m = Slope = 8/20 = 2/5
Now intercept;
b = -9 - (2/5(10)
b = -5
Now Write the equation as
y = 2/5x - 5
Hence, the equation of the line that passes through the point (−10,−9) and (10,-1) is; y = 2/5x - 5

what is the midpoint of (0,0.55) and (-3,6)
Answer:
(-1.5, 3.275)
Step-by-step explanation:
midpoint = ( x1+X2/2 , y1+y2/2)
=(0+(-3)/2, 0.55+6/2)
=( -3/2, 6.55/2)
=( -1.5, 3.275)

Write a function rule in terms of x and y for the line that contains the points (-7.4, -9.7) and ( 8.4, 6.1) .
Answer:
y = x + -2.3
x = -y - 2.3 (but why would one need this?...)
Step-by-step explanation:
(6.1 - (-9.7))/(8.4 - (-7.4)) = 15.8/15.8 = 1
6.1 = 8.4 + b
b = -2.3
Find the value of x.
Step-by-step explanation:
By using angle sum property
x-43+x-39+2x-18=180
4x=180+100
4x=280
x=280/4
x=70°
Find the Distance rounded to a whole number.
Give the distance between (2,1) and (5,2)
Answer:
[tex]\sqrt{10}[/tex]
Step-by-step explanation:
The distance between two points can be found using the Pythagorean Theorem [tex]a^{2} + b^{2} = c^{2}[/tex].
This is because, if you connected your two points with a line, that line could be defined as the hypotenuse of a right triangle. the base of that triange is the distance between the x coordinates ([tex]x_{2} -x_{1}[/tex]) and the height by the distance between the y coordinates ([tex]y_{2} - y_{1}[/tex]). Sine these are the sides of the right triangle, they are equal to a and b above (c is the hypotenuse that we are trying to find). So, we calculate the two distances above and get 3 and 1 (for x and y respectively). 3^2 + 1^ 2 =10. So the answer is square root 10.

What is the length of the unknown leg of the right triangle rounded to the nearest tenth of a foot?
Answer:
Around 8.8
Step-by-step explanation:
This problem requires the Pythagorean Theorem. We are given the hypotenuse and a leg, so we can plug in what we know.
[tex]{x^2+2^2}=9^2 \\{4+x^2}=81 \\x^2=77\\\sqrt{x^2}=77\\x=\sqrt{77}\\x=8.8, approximately[/tex]

Which expression is equivalent to 10s+s-3s10s+s−3s?
Answer:
9s-3s10s or 3-10s
Step-by-step explanation:
10s+s-3s10s+s-3s
first of all, we collect like terms
10s+s+s-3s-3s10s
=9s-3s10s
it could also be equal to
9s/3s-(3s10s/3s)
3-10s
when we divide through by 3s

Simplify the expression by combining like terms. Then,
evaluate the expression by substituting the given values
for the variables.
x=5 and y=2
y^2 + xy – 7y^2
Answer:
-14
Step-by-step explanation:
The like terms in this equation is y^2 and -7y^2 so combining the two the equation becomes:
xy-6y^2
Then we substitute the values in:
5×2-6×2^2 = -14

Last night 30cm of snow fell in 6 hours. If it continues snowing at the
same rate, how long will it take for 45cm of snow to fall?
Answer: 9 hrs for 45cm of snow to fall
Step-by-step
If 30cm = 6 hrs
Then divide 30/6 to get the unit rate of the amount of snow per hr
Which is 5/1
So 5cm per hr
Then add 30+5+5+5 to get 45
And since we know 5cm equal 1 hr
Add the original amount of hours which is 6 plus 3 ones
Which is 6+1+1+1
In total, it will take 9 hrs for 45cm of snow to fall.

The residence of a city voted on whether to raise property taxes the ratio of yes votes to no votes was 3 to 2 if there were 4440 total votes how many yes votes were there
Answer:
Y / N = 3 / 2
N + Y = 4440
Since Y = 3/2 N
3/2 N + N = 4440
5/2 N = 4440
N = 8880 / 5 = 1776
Y = 1776 * 3 / 2 = 2664
1776 + 2664 = 4440
2664 / 1776 = 3 / 2
