Answer:
y=10x+75
Step-by-step explanation:
Because y-y1 = m(x-x1)
Plug in the y1(5) and x1(-7)
So, y-5 = 10(x+7)
= y=10x+75
Answer:
129.6
Step-by-step explanation:
A= 1/2 bh
=7.8 x 9 x 1/2
= 35.1
A= 1/2 bh
=7x 9 x 1/2
= 31.5
31.5 x 3
= 94.5
<u>Add</u>
<u>35.1 + 94.5 = 129.6</u>
0.5a - 0.3 = 5
Add 0.3 to both sides:
0.5a = 5.3
Divide both sides by 0.5:
a = 10.6
Answer:
73.132 is the perimeter
Step-by-step explanation:
The perimeter of the square is 32 because 8x4.
The perimeter of the semicircle is 20.566 and times by 2 as there are 2 is 41.132.
41.132 + 32 = 73.132
Well.. I'm not sure if I remember this correctly but doesn't "i" represent the square root of -1? Therefore if you square a square root, they cancel out and you're left with -1 as your answer.
Steps would be to:
change "i" to the square root of -1
put the exponent 2 outside of that
cancel the square root and the exponent
answer= -1
