Answer:
line 2 of her working
Step-by-step explanation:
when multiplying the brackets out it is a negative times posative so she should have wrote -4 not +4
Step-by-step answer:
A line with slope (or gradient) m, passing through a point (x0,y0) can be represented by the equation:
(y-y0) = m(x-x0) ......................(1)
Here,
(x0,y0) = (1,7), and
slope/gradient = -2
Substitute values into (1) above gives
(y-7)=2(x-1)
Expand and simplify
y-7 = 2x-2
y =2x -2 + 7
y=2x+5
is the final answer.
Answer:
42.77
Step-by-step explanation:
The pattern is taking away 0.3. 43.07 minus 0.3 equals 42.77
Answer:
The slope is - 3
Step-by-step explanation:
Have a great day
F(x)=((1/4)x+9)/10 Because f of x = f(x), equals the quantity means =, one-fourth x is just (1/4)x, plus 9 is + 9, and all over ten means take everything previously said over ten.
