Answer:
.
Step-by-step explanation:
A line that goes through 
and 
where 
would have a slope of 
.
The slope of the line that goes through 
and 
would thus be:
.
Two lines in a cartesian plane are perpendicular to one another if and only if the product of their slopes is 
.
Thus, if 
and 
denote the slope of the first and second lines in this question, 
since the two lines are perpendicular to one another. Since 
, the slope of the first line would be:
.
Given that the first line goes through the point 
, the point-slope equation of that line would be:
.
.
Substitute in 
to find the 
-coordinate of the point in question:
.
Hello!
We have been given enough information to solve this question!
We know that the length of the rectangle is 2.5, and we also know how to find the area:
A = l × w
But we don't need the area, we need to find the width of the rectangle! You see, we had to multiply the length by the width to find the area.
Now, to find the width, we must flip the problem around and use the opposite of multiplication, which is division.
W = a ÷ l
W = 10 ÷ 2.5
W = 4
Therefore, the width of the rectangle is 4.
Answer:
f(x)=-1 and 15
Step-by-step explanation:
What you do is you put -2 and 2 into the x.
f(x) = -4(-2) + 7 = -1
f(x) = -4(2) + 7 = 15
f(x)=-1 and 15 are your answers.
Y - y₁ = m(x - x₁)
y - 6 = 7(x - (-4))
y - 6 = 7(x + 4)
y - 6 = 7(x) + 7(4)
y - 6 = 7x + 28
<u> + 6 + 6</u>
y = 7x + 34
