Answer:
x=-2, y=-6
Step-by-step explanation:
Simple substitution.
Since y is isolated in one of the equations already, you can plug it into the second equation.
x - 2(3x) = 10
x - 6x = 10
-5x = 10
x = -2
Sub. x = -2 into 3x = y:
3(-2) = y
y = -6
The cartesian plane is composed of four quadrants: quadrant I, II, III<span> and IV. Quadrant I has positive x and </span>y axes<span>. Quadrant II has negative </span>x axis<span> and </span>y axis<span>. Quadrant III has both negative x and </span>y axes<span> while quadrant IV has </span>positive x axis<span> and negative </span>y axis<span>. x value refers to the abscissa while y value refers to ordinate. Answer hence is A</span>
The value of TV is 11.
<h3>What is equation?</h3>
An equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.
Given:
TU= 8, UV = 3x and TV = x+10
TV= TU + UV
x +10= 8+ 3x
-2x = -2
x= 1
Hence, TV = 1+10= 11.
