Answer:
Step-by-step explanation:
I'm ASSUMING this goes with a photo supplied in another question.
Part E reflection across the x axis leaves the x value identical but negates the y value (x, y) → (x, -y)
Part I translating 6 up and 1 left subtracts one from the x value and adds 6 to the y value (x, y) → (x - 1, y + 6)
Part K Chanel has the correct sequence as following her instructions maps each point on triangle ABC perfectly to triangle DEF
Preston was close but he either needed to rotate about the origin 180° then translate up 6 and left 1, or rotate 180° about the point (-½, -½) and translate up 7.
I think the quickest conversion is to rotate 180° about the point (-½, 3)
We are given:
u+v
t=---------- and are to solve for u.
2
First, multiply both sides by 2; this will eliminate fractions:
2t = u + v. We want to solve this for u.
Subtracting v from both sides, we get 2t - v = u. Thus, u = 2t - v (answer)
Answer:
-5 = -3(5) + 10
Step-by-step explanation:
y = mx + b
They have given you the x and y values and the slope, m
y = -3x + b
sub the ordered pair
-5 = -3(5) + b
-5 = -15 + b
add 15
10 = b
-5 = -3(5) + 10
