Answer:
Choice C should be the answer
Step-by-step explanation:
Because all of them adds up to 180 since it is a straight angle.
£.075/5= £0.15
0.15x7= £1.05
7 bananas is £1.05
Answer:
f(x)=-2x+9 g(x)=-4x^2+5x-3Now, f o g (x) = f{g(x)} = f(4x^2+5x-3) = 2(4x^2+5x-3) + 9 = 8x^2+10x-6 + 9
Step-by-step explanation:
Answer:
D
Step-by-step explanation:
the equation of a line in point- slope form is
y - b = m(x - a)
where m is the slope and (a, b ) a point on the line
here m = 2 and (a, b ) = (- 2, 1 ) , then
y - 1 = 2(x - (- 2)) , that is
y - 1 = 2(x + 2)
Answer:
x = 3 and -2 are the two solutions.
Step-by-step explanation:
2x^2 -2x -12 = 0
First factor out a 2
2(x^2 - x - 6) = 0
2(x - 3)(x + 2) = 0
2 = 0 x - 3 = 0 x + 2 = 0
2 does not equal zero so this is an extraneous solution
x - 3 = 0 so x = 3
x + 2 = 0 so x = -2
