Answer:
infinite solutions
Step-by-step explanation:
3x−5y=15
6x−10y=30
Multiply the first equation by 2
2(3x-5y) = 2*15
6x -10y =30
The two equations are identical, which means they are the same line
That means they have infinite solutions
Hello!!
We know y = 7 + x. Substitute this into our other equation,
2x = (x + 7) - 10
2x = x - 3
x = -3
Now, we know that x = -3 so, we can conclude that the answer is choice B.
Hope this helps!! Let me know if you have ANY questions.
Answer:
63°
Step-by-step explanation:
To get the value of x we will use the Pythagoras theorem
hyp² = opp²+adj²
Given
hyp is the length of the ladder = 22ft
Adjacent is the distance from the base of the ladder to the wall = 10ft
Angle of elevation = x
Using the SOH CAH TOA identity
Cos theta = adjacent/hypotenuse
Cos x = 10/22
Cos x = 5/11
x = arccos(5/11)
x = arccos(0.4545)
x = 62.96°
Hence the best estimate of x is 63°
