B. obtuse scalene and D. obtuse isoceles
Answer:
i think the answer is B AND D
Step-by-step explanation:
2x + 5y = 10
Slope is -2/5 and y-intercept is 2
Step-by-step explanation:
2x + 5y = 10
5y = -2x + 10
y = -2/5 x + 10/5
y = -2/5 x + 2
Slope, m = -2/5
y-intercept, b = 2
For 5 and 6 you need the formulas I have attached for the "inscribed angle" and "external angle"
3w minus w is 2w, +4w is 6w. subtract 15 w both sides of the equation to get 33 on one side, and 9w on the other side. divide 9 on both sides, and the nswer is 3 and 2/3.
First, start by adding like variables on the same side of the equal sign
Next, subtract 15w from both sides to get like terms on the same side
Finally, divide -9 on both sides to get the variable alone
