Answer:
Required ordered pair is (0,0) for system of equation
Step-by-step explanation:
The given system of equation is
A). 
B). 
On simplifying the equation A

Take log on both side,
(12x) (log9) = (3y) (log9)
4x=y
To find the solution of the system of the equation :
Replacing value of y=4x in equation B,





We get,
x=0 and x=0.829
Since, 0.829 is not integer number
Only solution of equations is x=0
For the value of y
Replace value x in y=4x=0
Thus, Required ordered pair is (0,0)
Answer:
y=-3x+2
Step-by-step explanation:
as x goes up on y goes down 3
slope is change in y over change in x
-3/1=-3
the y intercept is (0,2) so the y intercept is +2
Answer:
The height of the wall is 9.17ft
Step-by-step explanation:
The length of the ladder is 10ft
Distance from the foot of the ladder to the wall is 4ft
The height of ladder is unknown.
To solve this question, you'll require a pictorial illustration of the situation. Kindly check attached document for that.
Since it's a right angle triangle, we have two sides with one sides unknown, we can use pythagorean theorem to find the third side.
The hypothenus (x) is 10ft
The adjacent is (y) 4 ft
The opposite (z) (height of the wall) is unknown.
X² = Y² + Z²
10² = 4² + Z²
100 = 16 + Z²
Z² = 100 - 16
Z² = 84
Z = √(84)
Z = 9.165 = 9.17ft
The height of the wall is 9.17ft
1500-125=1,375
so 1375 should be your answer.
