The equation of the line that passes through the point (-4,-7) and has a slope of 3/2 is y=3/2x-1
Step-by-step explanation:
I don't have a step by step explanation, but I went onto Desmos Graphing Calculator, entered in the point (-4,-7). From there, I found another point that follows the slope. From there, I started to make an equation and adjusted it as needed until I got the desired result as show.
Correct Answer:
y=21
21/3=7
Answer:
Solution : Option D
Step-by-step explanation:
Let's start by listing two cases made possible when r is positive, in ( r, θ ). Remember that in polar coordinates a point is expressed in an ordered pair, where r is the distance from the pole (in this case 9, as it lies on the 9th circle) and theta is the directed angle from the positive x - axis.
( 9, θ ) here theta will be the angle to the terminal side with respect to the positive x - axis. This angle will be 60 degrees more than 90, or 90 + 60 = 150 degrees
( 9, θ ) and here theta will be the remaining degrees, or 360 - 150 = 210 degrees. Right away your solution will be (9, 210°)
Answer: 4x + 3 = 39
Step-by-step explanation:
Because you don't know how much each pizza costs, you can write it as x.
You multiply x by 4 to get 4x and add 3 because thats how much the chips cost.
That added up should equal 39 because thats how much he spent.
