Answer:
A
Step-by-step explanation:
X values cannot repeat in a function, 3 is used as an X value twice in A, and therefore cannot be a function.
If this is graphed, you can use the vertical line test, if a vertical line on any point goes through other points, it is not a function.
In this case, just check if X repeats.
4. C)If two figures are congruent, then they are similar.
If they are congruent them shape and size are the same and hence they are similar
5. Ratio 4/3 smaller side is 21
Multiply to find large side
4/3×21= 28ft D)
6. Width went from 24 to 3 in divide to get ratio
24/3 =8 now divide the length by 8 to find the postcard length
32/8= 4 in A)
8. If they are similar you need to find the ratio y reduces from 8 is similar to 6 so link those 6/8
This is your ratio you can simplify it to 3/4 now y/6 should also = 3/4
Y/6=3/4
Y=18/4= 4.5 C)
9.C)DC
Answer:
The slope parallel to this line would be 2/3
Step-by-step explanation:
To find a parallel slope, start by finding the slope of the original line.
3y = 2x + 5
y = 2/3x + 5/3
So, we can see here that the slope is 2/3. Since parallel lines have the same slope, we know the parallel slope to also be 2/3
Answer:
30 oranges can be bought
Step-by-step explanation:
Answer:
15, 11, 60
Step-by-step explanation:
Let Joe's amount be x
x + x - 6 + 4x = 96
6x - 6 = 96
6x = 90
x = 15
Joe has 15
Kaitlin has 11
Miguel has 60
