Add the vertical distance between VU and the horizontal distance between UT and get the square root of what you added. That should be the answer.

Answer: 74</h3>
==================================================
Work Shown:
h(x) = 7x-5
h(2) = 7(2)-5
h(2) = 14-5
h(2) = 9
f(h(2)) = f(9)
f(x) = x^2-7
f(9) = 9^2-7
f(9) = 81-7
f(9) = 74
f(h(2)) = 74
-----------
Here's a slightly alternative approach:
f(x) = x^2 - 7
f(h(x)) = ( h(x) )^2 - 7
f(h(x)) = ( 7x-5 )^2 - 7
f(h(2)) = ( 7*2-5 )^2 - 7
f(h(2)) = ( 14-5 )^2 - 7
f(h(2)) = ( 9 )^2 - 7
f(h(2)) = 81 - 7
f(h(2)) = 74
Answer:
No Solution.
Step-by-step explanation:
Equality equation:
— 2y – Зу +8 = 8 — 5у – 12 (Given)
-5y + 8 = -4 - 5y (distributive property of equality)
-5y = -12 - 5y (subtraction property of equality)
= -12 (addition property of equality)
when you add 5y on both sides it cancels the 5y out, it's no solution.
Answer:
- ribeye steak: $24.37
- grilled salmon: $9.30
Step-by-step explanation:
If we let r and g represent the costs of a ribeye steak dinner and grilled salmon dinner, respectively, the sales figures give rise to two equations.
17r +15g = 553.74
22r +5g = 582.65
If we multiply the second equation by 3 and subtract the first, we have ...
3(22r +5g) -(17r +15g) = 3(582.65) -(553.74)
49r = 1194.21
r = 1194.21/49 ≈ 24.37
g = (553.74 -17r)/15 ≈ 9.30
The steak dinner costs $24.37; the salmon dinner costs $9.30.
_____
<em>Check</em>
17(24.37) +15(9.30) = 553.79 . . . not 553.74
22(24.37) +5(9.30) = 582.64 . . . not 582.65
There is no exact solution to this problem.
Answer:
The age difference between oldest the youngest is of 48 years.
Step-by-step explanation:
We can solve this question using a system of equations.
I am going to say that:
Kissi's age is x.
Esinam's age is y.
Lariba's age is z.
The ratio of the ages of Kissi and Esinam is 3:5
This means that 
, so 
That of Esinam and Lariba is 3:5
This means that 
, so
The sum of the ages of all 3 is 147 years
This means that 
What is the age difference between oldest the youngest
z is the oldest
x is the youngest.
First i will find y.
We have that, from the equations above: 
and 
So
The lesser common multiple between 5 and 3 is 15. So
Youngest:
Oldest:
Difference:
75 - 27 = 48
The age difference between oldest the youngest is of 48 years.
