Answer:
x=-4, y=2. (-4, 2).
Step-by-step explanation:
y=-x-2
y=1/4x+3
---------------
-x-2=1/4x+3
-x-1/4x-2=3
-5/4x=3+2
-5/4x=5
x=5/(-5/4)=(5/1)(-4/5)=-4/1=-4
y=-(-4)-2=4-2=2
A^2 + b^2 = c^
a^2 + 7.8^2 = 8^2
a^2 + 2.79= 2.83
a^2 = 0.04
a = 0.2m
i did that in my head so like it might be off or wrong but that’s the basic idea of it
75% is $135
<span>1% is $135/75 </span>
<span>So, 100% is (135/75) x 100 </span>
<span>So, the answer will be: $180 </span>
1.) -15.9, -15.2, -3.6, 3.6
2.) second one is already correct
3.)-2.3, -2.03, 2.03, 3.0
