Answer:
The inverse is 1/2x -3/2
Step-by-step explanation:
y =2x+3
Exchange x and y
x = 2y+3
Solve for y, subtracting 3 from each side
x-3 = 2y+3-3
x-3 =2y
Divide each side by 2
(x-3)/2 = 2y/2
1/2x - 3/2 =y
The inverse is 1/2x -3/2
17. First expand the left side:-
(2x + 1)(ax + b)
= 2ax^2 + ax + 2bx + b
= 2a x^2 + x(a + 2b) + b = 6x^2 - 5x + c.
Comparing coefficients:-
2a = 6 so a = 3
a + 2b = -5
3 + 2b = -5
2b = -5 - 3 = -8
b = -4
Also b = c, so c = - 4
Answer: a = 3, b = -4 and c = -4
Answer:
3 coefficients in this expression are: -2x, 5y and 9 (natural number)
Step-by-step explanation:
-6x + 5y + 4x + 9
= -6x + 4x + 5y + 9
= -2x + 5y + 9
3 coefficients in this expression are: -2x, 5y and 9 (natural number)
Hope this help you :3
It looks like you're given a question in slope intercept form.
Which is: y = mx + b, (m = slope and b = y-intercept)
Plug M and the point you know into the equation.
y = mx + b
8 = -3(2) + b
8 = -6 + b
14 = b
Now that you have your y-intercept, add that to the equation along with m, and what you know of the missing value (the point x, -4, you have the value of y, which is -4, so you're looking for the value of x)
-4 = -3x + 14
-18 = -3x
6 = x
So, your missing value is 6. I hope this was helpful and have a grreat rest of your day! ~ Saturns <3
