Lets create both equations:
y + 2x = -1
y = x^2
therefore:
x^2 + 2x + 1 = 0
(x + 1)^2 = 0
x = -1
y = 1
Answer:
Option B, - 7 + 12 = 5
Step-by-step explanation:
As you can see, the up line starts from the point 0 and it goes back by seven (- 7). Then from negative seven, it took 12 steps forward to zoom to positive 5 (+ 5). So + 5 is the last result of the process. It took 12 steps forward.
So with these statements kept in mind. Look at the options that would be described by these.
Let's start by this statement: "So + 5 is the last result of the process."
Option B and D only seem to have + 5 as the result.
Next statement: "Then from negative seven, it took 12 steps forward to zoom to positive 5 (+ 5)"
<em>Option B</em> is the most logical answer that is described by the statement.
From negative seven (-7) it took twelve steps forward (+ 12) to positive 5
(= 5)
The answer is C. You pay $128 in the third hour for both. Hope this helped
Answer:
(3,-3)
Step-by-step explanation:
If a coordinate (x, y) is dilated by a factor k, the resulting coordinate will be (kx, ky)
Given the coordinate (1, -1), if dilated by a factor of 3, the resulting coordinate will be (3(1), 3(-1)) = (3, -3)
Hence the required coordinate will be (3,-3)
