Given the line -9x-6y=18. Find the slope
SashulF [63]

Answer:

slope = - \frac{3}{2}

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Rearrange - 9x - 6y = 18 into this form

Add 9x to both sides

- 6y = 9x + 18 ( divide all terms by - 6 )

y = - \frac{3}{2} x - 3 ← in slope- intercept form

with slope m = - \frac{3}{2}

I WILL MARK YOU BRAINLIEST!!!!!
iren2701 [21]

Answer:

C. one solution

Step-by-step explanation:

The number of solutions can be found from the number of intersection points.

There are 2 lines, a parabola (curve) and a horizontal line that is parallel to the x axis.

We see that there is 1 point of intersection between the 2 lines, at (2,1)-right 2 and up 1. Therefore, this non linear system has 1 solution.

C. one solution is the correct answer.

The measures of the angles of a triangle are shown in the figure. solve for x
yuradex [85]

Answer:

solution,

x+41+59=180⁰ ( the sum of total angle of triangle is 180⁰)

or, x+ 100=180

or, X=180-100

so , X=80

Step-by-step explanation:

let us check

59+41+80=180

Outside temperature over a day can be modeled as a sinusoidal function. suppose you know the temperature is 75 degrees at midnig
antoniya [11.8K]

We presume the temperature is decreasing at midnight, so reaches a low at 6 a.m.. The amplitude of the variation is (87-63)/2 = 12 degrees. We want the period to be 24 hours, so the argument of the sine function will be 2π(t/24) = πt/12. Then we can write

... d = 75-12sin(π·t/12)
