CB is equal to 10m you can tell this bye the side DC being 20 m and the angle of DC is half of CB so that means that CB has to be 10 m
Answer:
Quest 1. is C, i.e 8. besides thier base are equal.
Quest 2. is D
Wuest 3. is C
Answer:
D
Step-by-step explanation:
We can work backwards.
First, notice that we have an open circle. So, we do not have "or equal to." So, we can ignore A and B.
Our final answer is all values less than -3. So:
We can multiply both sides by 3:
And then subtract 5 from both sides:
So, the answer that matches this will be D.
Instead of working backwards, you can also just solve each inequality. Since we have an open circle, we only need to solve C and D. If we solve C, we get x > -3, and if we solve D, we get x < -3 (as desired). So, D matches the graph shown.
Standard form is x + y = number
y + 4 = -6(x + 6)
y + 4 = -6x + -36
y = -6x - 40
6x + y = -40
