9 x 15 = ( 9 x 9) + (9 x 15)
Answer: Use the formula (base1+base2)/2 multiplied by height(3 in)
Step-by-step explanation: I can't see what the bottom base is, but lets say it is 12. 5+12=17, and 17/2=8.5. 8.5*3=25.5
Answer:25.5
4x+60+ x+15=180
5x+75=180
5x=105
x=21
Two linear angles are supplementary thereom
The point slope form of the line has the following form:
y – y1 = m (x – x1)
The slope m can be calculated using the formula:
m = (y2 – y1) / (x2 – x1)
m = (3 - 0) / (0 – 4) = - ¾
So the whole equation is:
y – 0 = - ¾ (x – 4)
y = - ¾ (x – 4) or
<span>y = - 0.75 (x – 4)</span>
