X=14
Co- interior angles are supplementary
9x+14+3x-2=180
12x+12=180
12x=180-12
X=168/12
X=14
Y=9X+14 (vertically opposite angles are equal)
Y=9*14+14
Y=126+14
Y=140

Answer:

x=14

y=140

Step-by-step explanation:

Using (9x+14) + (3x-2) = 180, we can solve this equation.

First add like values giving you 12x+12=180. Then subtract 12 from both sides giving you 12x=168.

Then divide both sides by 12 giving you x=14.

Finally, just simply set 9x+14 equal to y and substitute x for 14. This gives you 140=y

Hope this helped

If u = 2i - j; v= -5i + 4j and w = j find 4u (v -w).

Sedaia [141]

Answer:

-40

Explanation:

Given

u = 2i - j; v= -5i + 4j and w = j

Required

4u(v-w)

4u = 4(2i) = 8i

v - w = -5i + 4j - j

v - w = -5i + 3j

Substitute

4u(v-w)

= 8i(-5i+3j)

= -40(i*i) [since i*i = 1]

= -40

Hence the required solution is -40

The product of a nonzero rational number and an irrational number

Since irrational numbers are forever going, multiplying any nonzero rational number with an irrational number will make the product irrational as well
