Hey the answer is -0.2. You have to divide 10 by both sides to isolate the variable
Answer:
see explanation
Step-by-step explanation:
The equation of a line in point- slope form is
y - b = m(x - a)
where m is the slope and (a, b) a point on the line
y - 3 = - 9(x + 4) ← is in point- slope form
with slope m = - 9
Given a line with slope m then the slope of a line perpendicular to it is
= - = - =
The point (a, b) = (4, - 3), hence
y + 3 = (x - 4) ← equation of perpendicular line
Answer:
16n2−10n+22
Step-by-step explanation:
Given, the rate of growth of St. Augustine grass is cm per week.
We have to find the number of weeks that the grass grow to cm.
Let's take the number of weeks be x.
In 1 week the grass grow = cm
So in x weeks the grass grow = cm
So we can write,
To solve it for x, first we will move 7 to the right side by multiplying it to both sides. We will get,
Now to get we will move 4 to the right side by dividing it to both sides. We will get,
So we have got the required answer.
After 3 weeks the grass grow .
