Answer:
19 and 16
Step-by-step explanation:
Let x and y be the two numbers
x+y = 35
x-y =3
Add the two equations together
x+y = 35
x-y =3
---------------
2x = 38
Divide by 2
2x/2 = 38/2
x = 19
Solve for y
x-y = 3
19-y = 3
Subtract 19 from each side
19-19 -y = 3-19
-y = -16
y =16
Is this 2x to the power of 2?
if it is then this is easy
list it out (just to show you how its solved)
2x^2*4x^2
2x^2*(-12x)
2x^2*10
then list the other one
-5x*<span>4x2
</span>-5x*(-12x)
-5x*10
so the whole answer is
8x^4+(-24x^3)+(-20x^3)+20x^2+60x^2+(-50x)
Answer:
{-9.5, 1,7}
Step-by-step explanation:
For y =f(x)
domain is list of all values of x and range is list of all values of y
Given
ƒ(x) = 3x – 5
domain = {–1.5, 2, 4}.
thus,
range will be value of f(x)
when x = -1.5
x = 2 and x = 4
Thus,
for x = -1.5
ƒ(x) = 3*-1.5 – 5 = -4.5 - 5 = -9.5
\
for x = 2
ƒ(x) = 3*2– 5 = 6 - 5 = 1
for x = 4
ƒ(x) = 3*4– 5 = 12 - 5 = 7
thus,
range of ƒ(x) = 3x – 5 is {-9.5, 1,7}
Scientific notation is just a form of the number:
And the format is:
(A number greater than 1 but less than 10) times (10 to the power of x) ,where x can be positive or negative, but not a fraction or decimal
