Slope=-9/12 = -3/4
y=mx+b y=-3/4x+b
3=-3/4(-6)+b
b=3+9/2=7.5
Equation is y=-0.75x+7.5
Do it step by step
ab+3c
(-6)(-2)+3(5)
A negative times a negative is positive. (-)(-)=+
12+3(5)
12+15
=27
Answer:
209.1 cm2
Step-by-step explanation:
the area of the circle around the rectangle is 113.1 cm2 and the area of the rectangle is 12x8=96cm and 113.1+96=209.1
1) 24 / 18 = 1.33 and 28 / 21 = 1.33
so the exchange rate must be 1.33
2)1080 - 720 = 360
360 / 12 = 30
so the change is $30 per year
3) The slope would be a straight line and the y- intercept would be +30
Hope this helps! :)
<u>Answer</u>
AC = 34
<u>Explanation</u>
It is given that,ΔACE,
B is the mid point of AC
D is the mid point of CE
and F is the mid point of AE
If D and F are the midpoints, The line joining D and F parallel to third side AC.
The two triangles ΔACE and ΔFDE are similar and their sides are in the ratio 1/2
Here FD = 17 therefore AC = 34
