Answer:
trapezoid
Step-by-step explanation:
One pair of sides is parallel, so the figure is a trapezoid.
__
The upper right and lower left line segments both have slopes of -2/3. Since their slopes are the same, they are parallel. The slope is found by counting grid squares between points where the lines cross grid intersections. Those crossings occur down 2 and right 3 grid squares apart, so the slope is ...
m = rise/run = -2/3

Hence:
Answer:
x = 5,-2
Step-by-step explanation:
Multiply the whole equation by 3(x+1) to get rid of the denominator.
Then we solve the equation.
Since we are also solving rational equation, make sure that x ≠ -1 for this problem. Because if x = -1, the denominator is 0 which is undefined. Since our solutions are x = 5,-2 and not -1. Therefore the answer is x = 5,-2
Answer:
x=−4 and y=1
Step-by-step explanation:
Rewrite equations:
y=−2x−7;−3x+4y=16
Step: Solvey=−2x−7for y:
y=−2x−7
Step: Substitute−2x−7foryin−3x+4y=16:
−3x+4y=16
−3x+4(−2x−7)=16
−11x−28=16(Simplify both sides of the equation)
−11x−28+28=16+28(Add 28 to both sides)
−11x=44
-11x/-11=44/-11
x=−4
Step: Substitute−4forxiny=−2x−7:
y=−2x−7
y=(−2)(−4)−7
y=1(Simplify both sides of the equation)
x=−4 and y=1
