Answer:
3
Step-by-step explanation:
All points are the same distance from the origin. What helps me is visualizing the transformation in my head, though another method is drawing it, or learning the numerical rules. Like for example, a reflection across the y axis goes from (x, y) to (-x, y).
Here's a process of elimination:
1) The resulting image is upside down
2) The preimage is originally the same size as the intended image, so it would be smaller, upside down, and still far away.
4) The resulting image is still far from the intended image.
graph each inequality y-3x<-4
First we solve the inequality for y
Add 3x on both sides, so inequality becomes
y < 3x -4
Now we graph it
for graphing , replace < symbol with = sign
y= 3x - 4
Now make a table, assume some number for x and find out y
x y
-1 y=3(-1)-4 = -7
0 y=3(0)-4 = -4
1 y=3(1)-4 = -1
Now plot (-1,-7), (0,-4) ,(1,-1) on graph
Join all the points and make a dotted line ( dotted line for < or > symbol)
now we do shading
for < symbol we shade down
for > symbol we shade up
The graph is attached below
5.5 = 1.25x
1.25x = 5.5
x = 4.4
Answer : 4.4
Answer:
5.45

Answer:
The building is 76 feet tall
Step-by-step explanation:
Since the tree is halfway beween the stake and the building, then if D is the distance between the building (at ground level) and the stake, then the tree forms with the stake a rectangle triangle with base length equal to D/2 and Height equal to 38 feets.
The stake and the top of the buidling also form a triangle rectangle with base length equal to D. Since rectangle triangle preserve proportions, if we double the length of the base without changing the angle, then the heigth should also be doubled, and as a consecuence, the height of the building is 38*2 = 76 feets.
