Answer:
4 inches
Step-by-step explanation:
Actual dimensions:
Length = 15 feet
Width = 12 feet
Scale dimensions:
Length = 5 inches
Width = x inches
Write a proportion:
F(-3) = -12 - 3 = -15
h(2) = -10 + 7 = -3
-15 + (-3)
-18
Y=2x
so what you do is sub 2x for y in the top equation
x^2+(2x)^2=5
x^2+4x^2=5
5x^2=5
divide both sides by 5
x^2=1
sqrt both sides
x=1 or -1
sub back
y=2x
y=2(-1)
y=-2
y=2(1)
y=2
the solutions are (1,2) and (-1,-2)
Answer:
1. terms: 4r, 2, -6, and 3r like terms: 2 and -6, 4r and 3r
2.terms: 5h^2, -3h^2, - 4h, 3h, 7 like terms: 5h^2 and -3h^2, - 4h and 3h
3. 3m + 6
4. 15b + 2
5. 3x + 9
Step-by-step explanation:
1. 4r + 2 - 6 +3r
terms: 4r, 2, -6, and 3r like terms: 2 and -6, 4r and 3r
2. 5h^2 - 3h^2 - 4h + 3h + 7
terms: 5h^2, -3h^2, - 4h, 3h, 7 like terms: 5h^2 and -3h^2, - 4h and 3h
3. 6m + 7 - 3m-1
3m + 6
4. 3(5b +2) - 4
15b + 6 - 4
15b + 2
5. 2x + 4 + 5 + x
3x + 9
Answer: ~5
Step-by-step explanation:
It's been awhile for me but I think you do sin=opp/hyp
sin(45)=3sqrt(2)/x
x = 3sqrt(2)/sin(45) = (approx) 5
