Answer: Choice B
(-1,0), (-1,-2), (-3, -1), and (-3, -2)
============================================================
Explanation:
Let's focus on the point (2,0)
If we shift it 3 units to the left, then we subtract 3 from the x coordinate to get 2-3 = -1 as its new x coordinate. The y coordinate stays the same.
That means we move from (2,0) to (-1,0)
Based on this alone, choice B must be the answer as it's the only answer choice that mentions (-1,0).
If you shifted the other given points, you should find that they land on other coordinates mentioned in choice B.
3-(2x-5)=-4(x+2)
We simplify the equation to the form, which is simple to understand
3-(2x-5)=-4(x+2)
Remove unnecessary parentheses
3-2x+5=-4*(x+2)
Reorder the terms in parentheses
3-2x+5=+(-4x-8)
Remove unnecessary parentheses
+3-2x+5=-4x-8
We move all terms containing x to the left and all other terms to the right.
-2x+4x=-8-3-5
We simplify left and right side of the equation.
+2x=-16
We divide both sides of the equation by 2 to get x.
x=-8
Answer:
srry man i suck at civics, but i think it is B?
Step-by-step explanation:
Answer:
D = 0; one real root
Step-by-step explanation:
Discriminant Formula:
First, arrange the expression or equation in ax^2+bx+c = 0.
Add both sides by 9.
Compare the coefficients so we can substitute in the formula.
Substitute a = 1, b = 6 and c = 9 in the formula.
Since D = 0, the type of solution is one real root.
