Answer:
(-8,-3)
Step-by-step explanation:
This question is similar to the vertex form of a quadratic equation, so you can think of this equation like f(x) = (x-h)+k. Using this equation, you can determine the vertex (h,k) of |x+8|-3, which is (-8,-3).
1)
Solve using elimination
Multiply the first equation by 2 and the second by 5 so you can figure out x
10x-6y=-18
10x-25y=20
Subtract the two equations
19y=-28
y=-2
Plug y into the equation and you get x=-3
(-3, -2)
2. C Just model the equation
3. B Again, it's all about turning the word problem into equations
4. D. Use substitution and plug the x into the first equation.
5.
Multiply the whole first equation by 2.
You can see that because 4*2=8
8x+10y=16
Hope this helps.
