Answer:
Step-by-step explanation:
3y+21+hy+20 = 90
the sum of two complimentary angles = 90
m+n=90
then solve for y ( i think it is not letter H it has to be a number).
Y = mx+c
m is the gradient and c is the y-intercept so
4 = m(4) + (-4)
4 = 4m - 4
4m = 8
m = 2
Ans: Y = 2x - 4
The equation would be Y = 4x + 2
Answer:
Algebra tiles make solving equations, merging like words, or factoring polynomials a visual operation, similar to students using counters to make sense of addition in elementary school, or students using number lines to make sense of integers.
