Write the equation of the line that passes through the given points. (-1. -1.5) and (0, – 3.5)
Answers
Solving:
Slope can be found using the change in y over the change in x, or the “rise over run”.
-3.5 - -1.5 = -3.5 + 1.5 = -2
0 - -1 = 0 + 1 = 1
Slope (m) = -2/1 or -2
Since the second point’s x-coordinate is zero, that means its y-coordinate is the y-intercept.
Y-intercept (b) = -3.5
Slope-intercept equation: y = mx + b
So: y = -2x - 3.5
4(x-8)+12 equal 2(2x-9)
Answers
(Answer explained)
4(x-8)+12=2(2x-9)
We move all terms to the left:
4(x-8)+12-(2(2x-9))=0
We multiply parentheses
4x-(2(2x-9))-32+12=0
We calculate terms in parentheses: -(2(2x-9)), so:
2(2x-9)
We multiply parentheses
4x-18
Back to the equation:
-(4x-18)
We add all the numbers together, and all the variables
4x-(4x-18)-20=0
We get rid of parentheses
4x-4x+18-20=0
We add all the numbers together, and all the variables
-2!=0
There is no solution for this equation
can anyone help me with this problem with a full explanation?? thank you

Answer:
1, 3, 5
Step-by-step explanation:
let the 3 consecutive odd numbers be n , n + 2 , n + 4 , then
5(n + 2) = 2(n + n + 4) + 3 ( 5 times 2nd = twice sum of 1st and 3rd + 3 )
5n + 10 = 2(2n + 4) + 3
5n + 10 = 4n + 8 + 3
5n + 10 = 4n + 11 ( subtract 4n from both sides )
n + 10 = 11 ( subtract 10 from both sides )
n = 1
n + 2 = 1 + 2 = 3
n + 4 = 1 + 4 = 5
The 3 consecutive odd numbers are 1, 3, 5
Step-by-step explanation:
let the three consecutive odd number be x + 1 , x + 3 , x + 5
a/q
5 times the middle number = 5(x + 3) is
3 more than twice the sum of 1st and 3rd number = 3 + 2(x+1 + x + 5 )
so,
= 5 ( x + 3 ) = 3 + 2 ( x + 1 + x + 5 )
= 5x + 15 = 3 + 4x + 12
= 5x + 15 = 4x + 15
= -4x + 5x = 15 - 15 = 0
= x = 0
so, the 3 consecutive odd numbers are,
x + 1 = 1
x + 3 = 3
x + 5 = 5
and also a/q
5 times the middle number = 5×3 = 15
is equal to 3 more than twice the sum of 1st and 3rd number = 3 + 2(1+5) = 12 + 3 = 15
LHS = RHS

An angle 0 is drawn on the unit circle such that its terminal ray is in the second quadrant.
if sin 0 = 0.809, then what must be true about sin(-0)?
Answers
Answer:
sin(-θ) = -0.809
Step-by-step explanation:
To find this, simply perform the operation that is being asked, make theta negative.
If you want to find out what theta is in the first place, do this:
θ = arcsin(0.809)
θ = 54
Then to find sin of negative theta, substitute:
sin(-θ), or, sin(-54)
should equal to:
sin(-θ) = -0.809

Answers
Answer:
y-intercept is -18
Step-by-step explanation:
The total y=mx+b equation is y=4x-18, you can check in a calculator. I checked on a graphing calculator, and solved it via graphing on a piece of paper.
A line is drawn on the coordinate plane that passes through the point (3,-6) and has a slope of 4. The y-intercept of the line is -18.
What is a slope?In mathematics, a line's slope, also known as its gradient, is a numerical representation of the line's steepness and direction.
Given:
A line that passes through the point (x, y), with a y-intercept of b and a slope of m, can be represented by the equation,
y = mx + b.
If a line passes through two points (x₁ ,y₁) and (x₂, y₂) ,
then the equation of line is
y - y₁ = (y₂- y₁) / (x₂ - x₁) x (x - x₁)
To find the slope;
m = (y₂- y₁) / (x₂ - x₁)
m = 4 (given)
So, the equation of the line is,
y - y₁ = m(x - x₁) equation 1
And here
x₁ = 3 and y₁ = -6.
Substituting the values to the equation 1,
y - (-6) = 4 (x - 3)
y+6 = 4x -12
y = 4x -18.
Comparing with the slope-intercept form,
we get y-intercept b = -18
Therefore, the equation is y = 4x -18 and y -intercept of the equation is -18
