Equation of the line is y=mx+b
the line passing through point (1;-2) so x=1 y=-2
m=-0.5 so put all these values in equetion and found value of b
-2=-0.5*1+b
-2=-0.5+b
b=-1.5
so equation of the line is y=-0.5x-1.5
Answer:
equation of the line is y=-0.5x-1.5
Answer: The answer is D
Step-by-step explanation:
There are 5 plants x that should she plant in each row so that her 25 plants end up in a square (i.e., x plants in each of x rows)
<h3>Further explanation
</h3>
Maria wants to plant a small tomato garden in her yard. She bought 25 tomato plants, and she has read that ideally tomatoes are planted in a square grid to help them pollinate each other, as shown in the picture below.
How many plants x should she plant in each row so that her 25 plants end up in a square (i.e., x plants in each of x rows)? Express your answer as an integer.
If the gardener has x plants in each of her x rows, then the total number of plants will be
.
Since there are 25 total plants, the correct value of x will satisfy the equation
By taking the square root of both sides and note that 25 has both a positive and a negative square root because you can't have a negative number of plants, hence you only want the positive square root:
You can solve this part simply by simple arithmetic.

Answer:
X= 78
Step-by-step explanation:
180-115=65 that's one of the angles
and the other one is 360-323=37
and add the two angles together = 102
then finally 180-102=78 and that's it
