-3x^2 + 4xy - y^3 x = 5 and Y = 1

-56

Step:

Plug in the numbers into the equation

-3(5)² + 4(5)(1)-1³

Any expression multiplied by 1 remains the same. Evaultuate the power.

-3×25+4×5-1³

Multiply the numbers. 1 raised to any power equals 1.

-3×25+20-1

Multiply the numbers

-75+20-1

Calcualte the sum or difference and you get -56.

10.416 meters per second

step-by-step explanation:

distance=1 00 meters

time= 9.6 seconds in decimal form or 9 3/5 as a mixed number

average speed= 100/9.6

=10.416 meters per second or 10 52/125 as a mixed number.

look at the picture.

y-intercept for the function on a picture is 4 → point (0, 4).

y-intercept for the function

is for x = 0. substitute:

y-intercept is 8 → point (0, 8).
