What’s is the value for X?

k0ka [10]

The two angles are Alternate Exterior angles. For the lines to be parallel, the two angles need to equal each other:

2x-3 = x+4

Subtract x from both sides:

x - 3 = 4

Add 3 to both sides:

x = 7

Find the y-intercept and x-intercept of the line.<br> – 3x+9y= 14

pickupchik [31]

Answer:

$\huge\boxed{x-intercept=-\dfrac{14}{3}=-4\dfrac{2}{3}}\\\boxed{y-intercept=\dfrac{14}{9}=1\dfrac{5}{9}}$

Step-by-step explanation:

$-3x+9y=14\\\\x-intercept\ \text{for}\ y=0:\\\\-3x+9(0)=14\\-3x+0=14\\-3x=14\qquad\text{divide both sides by (-3)}\\\boxed{x=-\dfrac{14}{3}=-4\dfrac{2}{3}}}$

$y-intercept\ \text{for}\ x=0:\\\\-3(0)+9y=14\\0+9y=14\\9y=14\qquad\text{divide both sides by 9}\\\boxed{y=\dfrac{14}{9}=1\dfrac{5}{9}}$
