This one isn't too hard, just plug in each value!
x = -1
y = -4(-1) + 3
y = 7
x = 0
y = -4(0) + 3
y = 3
x = 1
y = -4(1) + 3
y = -1
x = 2
y = -4(2) + 3
y = -5
Answer:
No solutions
Step-by-step explanation:
So putting that into an equation it equals
2k+8=(4k+14)÷2
Move the 2 to the other side.
2∙2k+8=4k+14
Simplify.
4k+8=4k+14
It doesn't make sense so No Solutions
Answer:
domain is (-∞,∞)
(-∞,0) U(0,∞)
Step-by-step explanation:
The domain is the set of x values for which the function is defined
In f(x) there is no restriction for x. the function is defined for all x values
so domain is (-∞,∞)
The domain is the set of x values for which the function is defined
when x=0, e^0=1 that makes the denominator 0
Denominator 0 is undefined. So x cannot be 0
domain is (-∞,0) U(0,∞)
I think it could be 64 but I’m not totally sure
Answer:
Let AB be the flagstaff and CD be the vertical tower.
AB=10m=EC
BC=20m=AE
In triangle ABC we have,
tanx=AB/BC
tanx=10/20
1/tanx=20/10
10/tanx=20...........1
In triangle ADE we have
tan(90-x)=DE/AE
cotx=DE/20
1/cotx=20/DE
DE/cotx=20..............2
by eq1 and. eq 2 we get
10/tanx=DE/cotx
10/(AB/BC)=DE/(BC/AB)
10/(10/20)=DE/(20/10)
10×20/10=DE×10/20
DE=40m
Therefore height of vertical tower = DE+EC=40+10=50m
