m = 15
Step-by-step explanation:
10m = 10 - 5(m-7)
multiply -5 into the parenthesis
10m = 10 - 5m + 35

Answer:
both of those lines intersect each other and are equal lines
Step-by-step explanation:
Hello:
let : f(x) = <span>x3 − 6x2 + kx + 10
</span><span>If (x + 2) is a factor of x3 − 6x2 + kx + 10 : f(-2) = 0
(-2)^3-6(-2)² +k(-2)+10=0
-8 -24-2k +10 = 0
-2k =8+24-10
-2k = 22
k = -11</span>
