I just took and got it correct on the quiz.
Hello,
r²=(-4)²+(-6)²=16+36=52
x²+y²=52
Hello :
<span>x= 2 + y ....(1)
3x – 7y= 10 ....(2)
subsct in (2) :
3(2+y) -7y = 10
6+3y -7y = 10
-4y = 4
y=-1
x = 2-1 = 1
</span><span>the solution of this system of equations is (1 , -1)</span>
A- b = 47
a :b = 3 r 7
a = 47 + b
(47 + b) : b = 3 r 7
(47 + b) + 7= b x 3
47 + 7 = 3b - b
54 = 2b
b = 54 : 2
b = 27
a = 47 + b
a = 47 + 27
a = 74
