Answer:
(2,4)
Step-by-step explanation:
The range is the y values
y = x+5
Let y=7
7 =x+5
Subtract 5
7-5 x+5-5
2=x
Let y= 9
Subtract 5
9-5 x+5-5
4=x
The domain is (2,4)
Answer:
Q1:
150 pages is the answer
2 hours= 60+60minutes
So 120/40 =3
Answer= 50×3= 150.
Q2:
Using Work=men×days we get
Work=20×20
Work=400
Now, work is same and number of days are to be calculated
400=25×days
days= 16
400 = 25 x 16
so it will take 16 days
Step-by-step explanation:
Hope this helps!
<span>diff(x^2-11*x+24, x) = 2*x - 11
solve(2*x-11 = 0)
x = 11/2
y = (11/2)^2-11*(11/2)+24 = - 25/4
Vertex = (11/2, - 25/4)</span>
Answer:
No; the corresponding angles are not congruent
Answer:
4
Step-by-step explanation:
The y-variable can be eliminated by adding 3 times the first equation to the second:
3(2x -y) +(x +3y) = 3(11) +(-5)
7x = 28 . . . . simplify
x = 4 . . . . . . . divide by 7
_____
Using Cramer's Rule, you can also find the x-value. The math is not so different.
x = ((-1)(-5) -(3)(11))/(-1(1) -3(2)) = -28/-7 = 4
