On your own paper graph each system of equations and then describe it: y=x+4 3x+5y=10
ki77a [65]
Each equation form a straight slanting line. For the first equation, it is slanting towards the right which denotes that it has a positive slope. For the the second equation, its plot is slanting towards the left denoting that its slope is negative. Common to both equation is the point (-1.25, 2.75). At this point, the two lines intersect.

How to solve and simplify to the smallest fraction
Ostrovityanka [42]

Answer:

7/12

Step-by-step explanation:

When you multiply fractions you just multiply across. 7*6 = 42 and 8*9 = 72. The both of these numbers can be divided by six so 42/6 = 7 as the numerator. 72/6 = 12 for the denominator. 7/12 is the answer.

∠1=∠2+90°

∠2=∠3

∠2+∠3+128=180
