Answer:the answer is 3 and -1
Step-by-step explanation:
X=3
And
X=-1
Answer: 11 and -13
Step-by-step explanation:
first you need to isolate one variable so you can later plug it into the other equation
x+y = -2
y = -x - 2
now, you plug this y value into the next equation for the difference that equals 24 and solve for x
x-y = 24
x - (-x-2) = 24
2x + 2 = 24
2x = 22
x = 11
now that you have x, you can just plug it back into either original equation to get the corresponding y equation.
11 + y = -2
y = -13
proof:
11 - (-13) = 24
11 + (-13) = -2
Answer:
Step-by-step explanation:
Choosing two points on the dotted line to find equation of line.
The points are:
and
Slope of line can be calculated as:
Using point slope equation to find equation of dotted line.
where represents slope of line and represents y-intercept.
The y-intercept for the dotted line = 6 as it intersects the y-axis at (0,6)
So, the equation of line is:
The dotted line indicates that the line is not included in the solution.
The solution of the inequality is below the dotted line, so thus it would be less than the line.
So, the inequality would be:
The equation to find a hypotenuse is
A^2 + b^2=c^2
Plug in the numbers
30^2 + 40^2 = c^2
900 + 1600 =c^2
2500 = c^2
The square-root of 2500 = c
50=c
The hypotenuse of the triangle is 50
Hope this helps!
