Answer:
24.2 centimeters
Step-by-step explanation:
for height = f(time)
let x be the value of the height at 28hours
solving linearly
(28 - 15)/(32 - 15) = (x - 19)/(12.2 - 19)
solving we have
13/17 = (x - 19)/6.8
0.7647 = (x - 19)/6.8
cross multiplying,
x - 19 = 5.2
x = 5.2 + 19 = 24.2centimetres
A variable with a fraction exponent can be rewritten using a radical.
The equations would be A. radical equation
Answer:
C
Step-by-step explanation:
It is a function because it passes the vertical line test and Xs do not repeat, then count out the Y-values which are the range.
Assuming that Ralph budgeted $180 instead of $175 entertainment. He spent $35 per date and let "x" be the number of dates he attended. He spent $15 to go out with friends and let "y" the number of times that he go out with friends.
The correct expression is the "B" which is 35x + 15y =180.
The 2 small black lines through the sides of the triangle indicate that the 2 sides are the same length.
Because the 2 sides are the same the 2 bottom angles are also the same.
This means that 9x +3 = 84
Now we can solve for x:
9x +3 = 84
Subtract 3 from each side:
9x = 91
Divide both sides by 9:
x = 81 / 9
x = 9
