Answer:
50
Step-by-step explanation:
ABCD is quadrilateral. Sum of all the angles in a quadrilateral is 360. This means angle ADC will be 130.
ADE is a straight line. Angle ADC and angle CDE should sum up to 180. From here we can infer that angle CDE=x is 50
Answer:
y= 3x-17
Step-by-step explanation:
When finding a parallel equation to y=mx+b, mx will always stay the same. So we have to find b.
In order to do this you plug the parallel lines passing point into the equation.
-5(y) goes into the y's spot. 4(x) goes into the x's spot.
-5 = 3 x 4 + b
-5 = 12 + b
-5 - 12 = 12 - 12 + b
-17 = b
y=3x-17

Answer:
<h3> The equation has one valid solution and no extraneous of solutions.</h3>
Step-by-step explanation:
Given the expression;
4x/3x+1 = x/2x+10
We are to get the nature of the value of x
Cross multiply;
x(3x+1) = 4x(2x+10)
3x²+x = 8x²+40x
Collect like terms;
3x²-8x² + x - 40x = 0
-5x²+x -40x = 0
-5x²-39x = 0
-5x² = 39x
-5x = 39
x = -39/5
<em>Since we have just one value of x hence, the equation has one valid solution and no extraneous of solutions.</em>
