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).

What is the solution to the system of equations graphed below
Answer:
D) (0, -4)
Step-by-step explanation:
the solution is the point at which the two lines intersect
The cost or amount of money spent on the salmon fish of 8 ounces is 8.99 dollars.
She buys 8 ounces of smoked salmon at $17.98 per pounds .
Therefore lets convert ounces to pounds.
16 ounces = 1 pounds
She buys the fish at $17.98 per pounds.
Therefore,
16 ounces = 1 pounds
8 ounces = 0.5 pounds
Hence,
1 pounds = $17.98
0.5 pounds = ?
cross multiply
cost of 8 ounces of the salmon fish = 0.5 × 17.98 = $8.99

Let the number = x
Then, it would be: (x*36)/100 = 108
x*36 = 10800
x = 10800/36
x = 300
108 is 36 percent of the number 300.
Use a proportion to proceed to find the number.
A proportion is an equation that shows two ratios are equivalent.
In this case, we want to find the number that 108 is 36% of.
Write this proportion as:
108/x = 36/100
Here,
x represents the unknown number that we want to find.
Simplify this proportion by cross-multiplying:
(108)( 100) = 36x
Simplifying further, we get:
x = (10800)/36
x = 300
Therefore, 108 is 36% of 300.
Hence, the required number is 300.
