Answer:
y-7= -4(x-2)
Step-by-step explanation:
Y-Y1=M(X-X1) - point slope form equation.
Plug in each coordinate into their coresponding places, X1, Y1 and M (the slope).
Here's how to find the value of x:
<span>9 - 0.75 ( x + 8 ) - 5 = -6.5 find the difference of 9 - 0.75
</span><span>8.25 ( x + 8 ) - 5 = -6.5 add 5 to both sides
</span>
8.25 ( x + 8 ) = -1.5 distribute 8.25 to x and 8
8.25x + 66 = -1.5 subtract 66 from both sides
8.25x = -67.5 divide both sides by 8.25
x = 18.18181818...... the value of x is 18 2/11
hope this helps
The ratio last year was (families:plants) 1:3 so multiply each by 65 because 65 families to get 65:195 so 195 plants

1.
You can use the sine rule
a / sinA = b / sinB
Substitute the values in:
15 / sin112 = b / sin33
Multiply both sides by sin(33) to get b by itself
b = (15 / sin112) x sin33
Calculate this to get your answer of:
BC = 8.8 cm
2.
You can also use the sine rule here
sinA / a = sinB / b
Sub your values in:
sin84 / 32.4 = sin(y) / 21
Multiply both sides by 21 to isolate sin(y)
(sin84 / 32.4) x 21 = sin(y)
Calculate sin(y)
sin(y) = 0.6445975248
You now need to sin-1 this value to get u:
y = 40.13550596
To 1d.p, y = 40.1 degrees
