For question 8, you'll have to calculate the price for three lamps and the sofa together. Take the total price of the items and multiply the percentage.
For question 9, the formula for simple interest is price(P) x rate(R) x time(T) / 100. Put in the information given:)
This problem is an example of using the Pythagorean Theorem. a^2 + 64 = 100
a^2 = 36
a = 6
so the height is 6 feet
The point-slope form equation for this line is
y₁ - 9 = 4 (x₁ - 1), or D.Since these are all in point-slope form, all we need to do is find the slope and then input one value of (x, y) into the points. We start with the slope.
m =
m =
m =
m = 2
Now we need to input the values of one of the points and slope into the point slope equation: y₁ - y = m(x₁ - x).
Inputting (1, 9), we get
y₁ - 9 = 4 (x₁ - 1)
The equation that fits it is D., so that means that the only answer to this question is
D.
The answer is (●’◡’●)ﾉ BBBB !!!
The <em><u>correct answer</u></em> is:
D) Closed circle on 8, shading to the right.
Explanation:
First we must solve the inequality:
x - 3 ≥ 5
Add 3 to each side:
x - 3 + 3 ≥ 5 + 3
x ≥ 8
To graph this, we want a circle on 8 Since it is "greater than or equal to," 8 is included in the solution set. This means the circle will be closed.
Since it is "greater than," we want the numbers to the right of 8 on the number line.
This means the inequality will be a closed circle and shaded to the right.
