Answer:
x=9, y=3
Step-by-step explanation:
-4x+6y=-18
y=-2x+21
-4x+6(-2x+21)=-18
-4x-12x+126=-18
144=16x
x=9
y=-2x+21
y=-18+21
y=3
Answer:
photomath thats what u should use or put it in a calculator
<span>From the given information cosec theta times tan theta times cos theta, writing this triginometric expression as an equation.
cosec theta x tan theta x cos theta
cosec theta = 1/sin theta
tan theta = sin theta / cos theta
Calculating the equation after substituting
(1/sin theta) x (sin theta / cos theta) x (cos theta) = 1</span>
Answer: If the original equation is y = 3x -4, the slope is 3.
Any equation of a line parallel to the line <u>y = 3x -4</u> will have a slope of 3.
Step-by-step explanation:
In slope-intercept form, y =mx + b the coefficient of x, m is the slope.
Here 3 is that value.
It is very unusual to have two equal signs in a question about slope.
I am not sure what to do with the <u><em>=8y + 1</em></u>
Is this supposed to be another equation in the system, missing a term?
