Answer:
$1.45
Step-by-step explanation:
9.25 - 2 = 7.25
7.25 ÷ 5 = 1.45
3+4 = 7
so
21 / 7 3
3 x 3 = 9
3 x 4 = 12
answer
£21 in ratio 3:4 is £9:£12
Answer:
x = -2
Step-by-step explanation:
The way you can tell if the graph is going to cross the x-axis or just touch the x-axis is by looking at the power of the factor.
(x - 5)^3 has a power of 3 which is an ODD number. An ODD power means that the graph will cross through the x-axis.
(x + 2)^2 has a power of 2 which is an EVEN number. An EVEN power means that the graph will touch the x-axis.
To find where it will touch the axis set the factor equal to zero and solve.
(x + 2) = 0
subtract 2 from both sides
x = -2
It is just 5.0 and you move the decimal right six places
<u> b</u> = 1.5
-3
Cross Multiply
b = - 3 * ( 1.5 )
b = - 4.5
