The first step would be D
Answer:
The length of the hypotenuse is 37cm
Step-by-step explanation:
we know that the area of the triangle can be found by 1/2bh. we can plug in what we know into this formula to find the height.
a=1/2bh
210=1/2(12)h
210=6h
h=35cm
now, since it's a right triangle, we can find the length of its hypotenuse by using the pythagorean theorem, using c to represent the length of the hypotenuse:
12^2+35^2=c^2
c^2=144+1225
c^2=1369
c=37
so, the hypotenuse is 37cm
The graph of an absolute value parent function is a pair of rays in quadrant 1 & 2, as shown in the graph.
The absolute value function is
f(x) = |x| or y = |x|
We also know that the absolute function can be wriiten as
y = |x|
=> y = x or y = -x
Comparing with y = mx + c
We get
m = 1 or m=-1 and c = 0
c = 0 implies that the line passes through the origin.
Hence the slopes shall be -1, 1 & the line passes through the origin.
Option A, B & D are the right answers.
Answer:
Step-by-step explanation:
y=x+9
10+2x=-2(x+9)
10+2x+2x+18=0
4x=-28
x=-7
