Answer:
Step-by-step explanation:
2 is like terms
1 one is coeff
3 is const
4 is expression
5 is trem
6 is variable
Equating the y's:-
3x + c = x^2 - 5x + 7
x^2 - 8x +7 - c = 0
If y = 3x + c is a tangent then there will be duplicate solutions to this equation
That is the discriminant b^2 - 4ac = 0. So we have:-
(-8)^2 - 4 * 1 * (7 -c) = 0
64 -28 + 4c = 0
4c = - 36
so c = -9 answer
Answer:
900 m
Step-by-step explanation:
since it is an irregular figure, you would have to find the area of the rectangles making it up separately.
18 x 30 = 540
6 x 60 = 360
540 + 360 = 900
(A)
Step-by-step explanation:
Multiply both sides by (x + 3)(x - 3)
4(x + 3) + 2 = (x- 3)
4x + 12 + 2 = x - 3
3x = - 17
or
x = -17/3
Answer:
or
27
Step-by-step explanation:
Any regular whole number (37 for example) is over one so it would look like . Multiplying fractions involve just multiplying the numerators and denominators together, therefore it would look like ×. Now just multiply the top and bottom numbers together and this will leave you with . But if you'd like to make it into a mixed number (more simplified version of ) then you would get 27 .
