Answer:
Step-by-step explanation:
3x + y + 72 = 180
3x + y = 108 .... <em>(1)</em>
2x + y = 90 ..... <em>(2)</em>
(1) - (2)
<em>x = 18°</em>
<em>y = 54°</em>
X=3
X/-3 = -1 ,Leave X by itself so multiply by -3 on both sides.
X = -1*-3
X = 3, negative times negative equals positive.
Answer:
x = 12
Step-by-step explanation:
9/36= x/48
9/36 = 1/4
1/4 = x/48
bring 48 to the other side
1/4 × 48 = x
48/ 4 = 12
x = 12
range= biggest number - smallest number
Answer: Between x = -2 and 0.
Explanation: Let's first look for an interval where the gradient is decreasing. That is, if we were given the function for each curvature or line, the derivative would be negative.
We see that only two places have a decreasing gradient (between 0 and -2 and 2 and 4).
Now, the question asks for a non linear line. So, we want to look for a curve instead of a line and thus, the only viable interval is between -2 and 0.
