14x + 4y = 24
D(4, 4)
D(3, 3)
D(8, 4)
Answer:
The correct option is;
D(4, 4)
Step-by-step explanation:
The given coordinates of the points are, A(2, 3) B(8, 7), C(6, 1), therefore, the coordinates of the point D that will make CD perpendicular to AB will have a slope = -1/m, where, m = the slope of the line segment AB
The formula for finding the slope, m, of a segment, given the coordinates of two points on the straight line segment (x₁, y₁), (x₂, y₂)
Therefore, for, the segment AB, we have;
m = (7 - 3)/(8 - 2) = 4/6 = 2/3
m = 2/3
Therefore, to make the segment AB perpendicular to the segment CD, the slope of the segment CD will be -1/m = -1/(2/3) = -3/2
The equation of the segment CD in point and slope form is therefore;
y - 1 = -3/2×(x - 6)
y - 1 = -3·x/2 + 9
The standard form of the equation of the segment CD is therefore;
y = -3·x/2 + 9 + 1 = -3·x/2 + 10
y = -3·x/2 + 10
The point that satisfies the above equation is the point (4, 4) because;
4 = -3 × 4/2 + 10
The correct option is therefore, D(4, 4).
Answer: C) a bell-shaped curve, better known as a normal distribution
Step-by-step explanation:plato only
Answer:
y = x + 1
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = - 2x + 2 ← is in slope- intercept form
with slope m = - 2
Given a line with slope m then the slope of a line perpendicular to it is
= - = - =
The line crosses the y- axis at (0, 1) ⇒ c = 1 , then
y = x + 1 ← equation of perpendicular line
Answer:
The percentage saved is 1.5% .
Step-by-step explanation:
As given
You plan to buy $12,000 in computers at a local chain store. There are two stores located about the same distance from your office but in different cities with different tax rates.
One city has a tax rate of 7% and the other has a tax rate of 8.5%.
As
7% is written in the decimal form .
= 0.07
Tax price at 7% tax rate = 0.07 × Cost of the computer
= 0.07 × 12000
= $ 840
8.5% is written in the decimal form .
= 0.085
Tax price with 8.5% tax rate = 0.085 × Cost of the computer
= 0.085 × 12000
= 1020
Change in the tax rate = Tax price with 8.5% tax rate - Tax price at 7% tax rate.
= 1020 - 840
= $180
Percentage saved = 1.5%
Therefore the percentage saved is 1.5% .
