Insert y in the second equation and solve for x:
4x+(x^2-8)=-8
4x+x^2-8=-8
4x+x^2=0
x^2+4x=0
x = -4
Now you insers this x-value in the first or second equation (i use the first):
y=(-4)^2-8=16-8=8
Therefore the conclusion must be x=-4 and y=8
Answer:
50%(1/2) I geuss
Step-by-step explanation:
1/5=0.2=20%
20%+30%=50%
50%=1/2(or 2/4,or 3/6)
If AC bisects < BAD, it means it cuts it into 2 equal parts
so < BAC = < CAD
3x + 12 = 5x
12 = 5x - 3x
12 = 2x
12/2 = x
6 = x
< BAC = 3x + 12.......3(6) + 12 = 30 degrees <===
Answer: Company B charges $(15.5+0.12x) more for x miles than company A.
Step-by-step explanation:
Let x = Number of miles.
Total charge = Flat charge + (charge per mile) x (Number of miles)
Given:
For Company A ,
Flat charge= $45
Charge per mile = 11 cents = 0.11 [ 1 dollar = 100 cents i.e. 1 cent = 0.01 dollar]
Total charge = 45+0.01x
For Company B,
Flat charge= $60.50
Charge per mile = 13 cents = 0.13
Total charge = 60.50+0.13x
Difference in charge = Charge for company B - Charge for company A
= 60.50+0.13x-(45+0.01x)
= 15.5+0.12x
Hence, Company B charges $(15.5+0.12x) more for x miles than company A.
U is a point in the line segment TV
TU + UV = TV
TU = 12
UV = 3
<h3>TV = 12+3 = 15 </h3>
<h2><u>TV = 15</u></h2>
