Answer:
range is {‒7, 2, 11, 20}
Step-by-step explanation:
a y=3(‒4)+5 c y=3(2)+5
=‒12+5 =6+5
= ‒7 =11
b y=3(‒1)+5 d y= 3(5)+5
=‒3+5 =15+5
=2 =20
so the range is {‒7, 2, 11, 20}
i think it is clear answer i hope it helps you
12/(5+10)=m/10
4/5=m/10
m=8

To find an equation of a line when given the slope and a point we use the formula
From the question we have
We have the final answer as

Here is a trick that not a lot of people know
(# of terms)*(first+last)/2
(in case you don't know, * means multiply and / means divide)
Here we would use the idea that the post and its shadow form a triangle and the tree and its shadow form a triangle and the side lengths of these two triangles are of the same ratio, ie. if the height of the tree is given by h then:
5/8 = h/48
h = 48*(5/8)
h = 6*5 = 30
Thus the tree is 30 ft tall
