Answer:
Step-by-step explanation:
49.4 degrees
Step-by-step explanation:
In Triangle AXY,
We want to determine the angle of elevation from the point is standing to the top of the flagpole, which is the angle at V in the diagram.
In Triangle XVY
|VY|=36 feet
Therefore, the angle of elevation from the point is standing to the top of the flagpole is 49.4 degree to the nearest tenth of a degree.
I think i might of clicked on gthe wrong question sorry
you need to find how much the output changes for each unit change in the input. (ie from an input change from 5 to 6 the output changes by three units and an input change of 3 (2 - 5 ) units the output changes by 9 units). This will give you the gradient of the equation. then you have to find out the y intercept by finding what the output is when the input is 0. Do this by multiplying the input by the gradient and then subtracting it from that inputs output. This will give you the answer A) 3x
(Sorry, its a bit wordy :) )
Answer: multiply the other side by 3 also
Step-by-step explanation:
What happens to one side must also happen to the other side. This is the only way to keep equations equal when changing constants and variables
Answer:
Step-by-step explanation: Let x represents Sara's age, since Ralph is 3 times as old, the Ralph's age will be 3x.
In 4 years time, Sara will be x+ 4 , Ralph will also be 3x + 4
It was said that Ralph will be as twice as Sara's age in 4 years
⇒ 3x + 4 = 2 ( x+4)
⇒ 3x + 4 = 2x + 8
collecting the like terms
3x - 2x = 8 - 4
x = 4
Since x represents Sara's age, then Sara is 4 years and since Ralph is presently 3 times Sara's age, then Ralph's age is 3 x 4 = 12 years
