Describe how to plot -3 3/4 on a number line?
2 answers:
On the number line, negative numbers go to the left. Since -3 3/4 is negative, go 3 spaces to the left.
When plotting a fraction or decimal on a number line, you need to estimate. If there are half marks in between the numbers, plot the point near the half mark. If it's -3 3/4, count 3 spaces, then go to the half mark of -3 to -4, and plot the 3/4 in between the -3 and -4 half mark. If there is no half mark, place it near the -4 mark.
The red line represents the half mark, the blue line represents where the point would go. Notice how when negative, the numbers go higher as they go left.

Answer:
g(x) =
Step-by-step explanation:
Parent function given in the graph attached is,
f(x) =
Function 'f' passes through a point (1, 1).
If the parent function is stretched vertically by 'k' unit,
Transformed function will be,
g(x) = k.f(x)
Therefore, the image of the parent function will be,
g(x) =
Since, the given function passes through (1, 2)
g(1) = = 2
⇒ k = 2
Therefore, image of the function 'f' will be,
g(x) =

we have that
cos(alfa) triangle ABD=12/y
and
cos(alfa) triangle ABC=y/28
then
12/y=y/28----------> y²=12*28=336----------> y=√336=4√21
y=4√21

</span>(16+12)²=x²+y²----------? x²=28²-(4√21)²--------> x²=784-336
x=√448=8√7
the answer is
x=8√7
y=4√21
