A) the output would be -9,4 because using the rule Alivia created (x,y)➡(x-3,y+4) -6 (which is the x value) subtract 3 equals -9. 0, which is the y value plus 4 equals four.
b) The output would be 0,0 because using the same rule 3 subtract 3 is 0 and -4 plus 4 is 0.
c) Honestly I tried to determine whether the rule was a function and I am having a hard time determining. But I can tell you that x values cannot have more than one y value while y can have more than on x value.
please vote my answer brainliest. thanks!
The best step to do next is to add 80 to both sides of equation:
5 ( x² + 8 x ) + 80 = 14 + 80
and since 80 = 5 · 16
5 ( x² + 8 x + 16 ) = 94 Answer : B )
After that we will continue like this:
5 ( x + 4 )² = 94
( x + 4 )² = 18.8 ... etc
The total cost would be $9.45
2.5 mins. time is equal to distance divided by the speed. so 17.5 divided by 7 is 2.5
Answer:
sqrt(10) *x
Step-by-step explanation:
Since this is a right triangle, we can use the Pythagorean theorem
a^2 + b^2 = c^2
x^2 + (3x)^2 = hypotenuse ^2
x^2 + 9x^2 = hypotenuse ^2
10x^2 = hypotenuse ^2
Take the square root of each side
sqrt( 10x^2) = sqrt(hypotenuse ^2)
sqrt(10) * x = hypotenuse
