Answers

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

Write the equation of the line that passes through the given points. (-1. -1.5) and (0, – 3.5)

Answers

Answer (in slope-intercept form): y = -2x - 3.5

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

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
