21x + 28 = 156 - 2
21x = 154 - 28
21x/21 = 126/21
X = 6
Answer:
given,triangle EFG is congruent to triangle HIJ,THEIR corresponding sides are equal,
so, 10x=x+45
10x_x=45
or,9x=45
therefore , x=5
again,
3y = y+14
or, 3y_y=14
or, y=14/2
therefore the value of y is 7.
so the value of x is 5 and y is 7.
hope its helpful to uh...
Rewrite the parabola in standard form and use this formula to find the vertex (h,k).
= (2,-1)
8: slope is 1/2 and y intercept is 0
9: slope is 7/4 and y-intercept is 0
