The ratio is written as a:b = c:d, by proportion using the same given, it is written as a/b = c/d. In the problem, d is the missing number, so we will cross multiply it to get the value,
d = cb / a
d = (3)(1) / 75
d = 3/75 = 1/25
Only 8 is not a function. it is not because there are 2 lines coming from the first domain elemenr
Answer:
The slope is 3
Step-by-step explanation:
12x−4y=3
Solve for y
Subtract 12x from each side
-12x +12x−4y=-12x+3
-4y = 12x+3
Divide each side by -4
-4y/-4 = -12x / -4 +3/-4
y = 3x -3/4
This is in slope intercept form
y = mx+b where m is the slope and b is the y intercept
The slope is 3
The answer is 9x² - 36x + 35
FOIL Method or Box Method can be useful in solving this problem.
First Terms Product: 3x × 3x = 9x²
Outside Terms Product: 3x × -5 = -15x
Inner Terms Product: -7 × 3x = -21x
Last Terms Product: -7 × -5 = +35
Combining like terms results in the answer given above.
Answer:
x^4- x^3- 4x^2-3
Step-by-step explanation:
Given
f(x)= x^4- x^2+9
And
g(x)= x^(3 )+ 3x^2+12
We have to find
(f-g)(x)= ?
The operations on functions are as easy as the operations on numbers or polynomials.
We have to subtract the functions to find the above mentioned operation.
=(f-g)(x)=f(x)-g(x)
(f-g)(x)=[x^4- x^2+9]-[x^(3 )+ 3x^2+12]
The minus will change the signs of function g.
= x^4- x^2+9- x^(3 )- 3x^2-12
= x^4- x^3- x^2- 3x^2+9-12
=x^4- x^3- 4x^2-3
