Answer:
the y-values for the x-values, starting with -3, are:
-5, -4, -3, -2, -1, 0, 1
Step-by-step explanation:
for each, plug the x-value into the equation <em>y = x - 2</em> and get the result
example, when x = -3 then y = (-3 - 2) which is -5
Answer:
1:5
Step-by-step explanation:
5/5 and 25/5
so 1:5

Answer:
Step-by-step explanation:
The line representing Murphy street goes through point (0, 3) and has a slope of 2/1 = 2. Its equation is then ...
y = mx + b
y = 2x +3
The translation vector transforms this equation* by adding -1 to y, and replacing x with x-1.
y = (2(x-1)) +3) -1
y = 2x -2 +3 -1 . . . . eliminate parentheses
y = 2x . . . . . . . . . . . the equation for Nolan street
__
Of course, adding (1, -1) to the point (0, 3) moves it to ...
(1, -1) +(0, 3) = (0+1, -1+3) = (1, 2)
The image of (0, 3) is (1, 2).
_____
* f(x) is translated by (a, b) this way: g(x) = f(x-a) +b. Here, f(x) = 2x+3 is translated to f(x-1)+(-1) = (2(x-1) +3) -1.
Answer:
A, B, and C
Step-by-step explanation:
Let's simply the equation first
- -2(-8 - 4y + 3/4)
- 16 + 8y - 1 1/2
What did Daniel do wrong?
Well, let's break down what I did and compare it to Daniel.
- <em>I multiplied -2 and -8x to get 16x. A negative number times a negative number is positive, and 2 times 8 is 16</em>
Daniel, on the other hand, added the two terms.
The first term should be positive (A)
- <em>I multiplied -2 and -4y to get 8y. The same sign rules apply.</em>
Daniel got a negative number, but it is supposed to be positive (B)
- <em>I multiplied -2 and 3/4 should be -6/4, which simplifies to -1 2/4 which is further reduced to -1 1/2</em>
Daniel multiplied and simplified incorrectly (C)

Answer:
Hi there! The answer to this question is (x−79/16)^2+(y−2)^2=(4225/256)
