parallel lines have the same slope; it means that if we have a line with a slope of -8, then the line parallel to the given line has the same slope (-8)
now, we are also given a point that the line passes through:
(9, 7)
we can use point-slope form:
[tex]\pmb{y-y1=m(x-x1)}[/tex]
[tex]\pmb{y-7=-8(x-9)}[/tex] (point-slope form)

A real estate agent earns 3% commission on each house she sells. If she sells a 150,000 house, how much commission will she get?
Answer:
4,500

150,000x.03=4500
The commission of the real estate agent is 4500 which is 3% of 150,000.
What is the percentage?A percentage is a value per hundredth. Percentages can be converted into decimals and fractions by dividing the percentage value by a hundred.
Given, A real estate agent earns a 3% commission on each house she sells and she sells a 150,000 house.
So, His commission is 3% of 150,000.

Find the area of the Regular Octagon below and show all mathematical reasoning.
9514 1404 393
Answer:
200√2 square units
Step-by-step explanation:
The area of a regular polygon with n sides and radius r is given by the formula ...
A = (n/2)r²·sin(360°/n)
Here, we have n=8 and r=10, so the area is ...
A = (8/2)(10²)sin(360°/8) = 4·100·√2/2
A = 200√2 . . . square units

Savannah gave the cashier $20 to pay for 3 pairs of socks. The cashier gave her $5.03 in change. Each pair of socks cost the same amount. What is the cost in dollars and cents for each pair of socks? Once you solve the problem, circle/highlight your answer.
Answer: $4.99
Step-by-step explanation:
The amount that Savannah paid for the 3 pairs of socks will be gotten by subtracting $5.03 from $20 which will be:
= $20 - $5.03
= $14.97
Since each paid of socks cost thesame amount, the cost of each pair of socks will be:
= $14.97/3
= $4.99
Each pair of socks cost $4.99

2) Which statement is modeled by 2p + 5 < 11?
(1) The sum of 5 and 2 times p is at least 11.
(2) Five added to the product of 2 and p is less than 11.
(3) Two times p plus 5 is at most 11.
(4) The product of 2 and p added to 5 is 11
Answer:
(2) Five added to the product of 2 and p is less than 11.
Step-by-step explanation:
2p + 5 is represented by five added to the product of 2 and p.
This is because 2p is the product, and 5 is added to it.
The less than inequality means that 2p + 5 is less than 11.
So, the correct statement is (2) Five added to the product of 2 and p is less than 11.

Clare is deriving the quadratic formula by solving ax^2+bx+c=0 by completing the square.
She arrived at this equation:
(2ax+b)^2=b^2-4ac
Briefly describe what she needs to do to finish solving for I and then show the steps.
Answer:
Clare starts with:
a*x^2 + b*x + c = 0
And she gets to:
(2*a*x + b)^2 = b^2 - 4*a*c
Now we want to show the final steps to solve the equation (isolating x)
First, we apply the square root to both sides:
[tex]\sqrt{(2*a*x + b)^2} = \sqrt{(b^2 - 4*a*c)}[/tex]
Because the square root has two solutions, (one negative and one positive), we will write:
[tex]2*a*x + b = \pm \sqrt{b^2 - 4*a*c}[/tex]
Now we subtract b in both sides:
[tex](2*a*x + b) - b = \pm \sqrt{b^2 -4*a*c} - b[/tex]
[tex]2*a*x = \pm \sqrt{b^2 -4*a*c} - b[/tex]
Now let's divide by 2*a in both sides:
[tex]2*a*x/(2*a) = \frac{\pm \sqrt{b^2 -4*a*c} - b}{2*a}[/tex]
[tex]x = \frac{\pm \sqrt{b^2 -4*a*c} - b}{2*a}[/tex]

1. Calculate the value of 8. 1 × 103 − 2. 4 × 102 in standard form.
2. Blood comprises 8% of the weight of a human. Amy weighs 40kg. Find the weight of her blood.
Step-by-step explanation:
1. We need to find the value of 8.1 × 10³ − 2.4 × 10² in standard form.
We can also write its as :
8.1 × 10³ − 2.4 × 10²
81000 − 240
Standard form = 80760
2.
Amy's weight = 40 kg
Blood comprises 8% of the weight of a human.
Weight of her blood,
[tex]W=8\%\ of\ 40\\\\=\dfrac{8}{100}\times 40\\\\=3.2\ kg[/tex]
So, the weight of her blood is equal to 3.2 kg.
During the first several rounds of a golfing league, Nate made par or better on 34 out of 85 holes. Based on this relative frequency, how many pars or better could he be expected to make on the remaining 150 holes? Round to the nearest whole number if necessary.
Answer: 60 holes
Step-by-step explanation:
Nate made par or better 34 out of 85 holes. You need to use this to find the rate at which he makes par or better holes:
= 34 / 85 * 100%
= 40%
40% of the time he makes par or better holes.
If there are 150 holes left, he will make par or better of:
= 40% * 150
= 60 holes

Answer:
[tex]A=54.95\ ft^2[/tex]
Step-by-step explanation:
The angle of shaded sector = 360-332 = 28°
The radius of sector, r = 15 ft
We need to find the area of the shaded sector. The formula for the area of the sector is given by :
[tex]A=\dfrac{\theta}{360}\times \pi r^2\\\\=\dfrac{28}{360}\times 3.14\times (15)^2\\\\A=54.95\ ft^2[/tex]
So, the area of the shaded sector is equal to [tex]54.95\ ft^2[/tex].

Answer:

Each stripe is 1/18 yards thick, and the fence post if 5/6 yards. Therefore, we have to find how many 1/18s can go into 5/6. Thus, this is a matter of division, and we do 5/6 divided by 1/18 to find how many stripes we can have.
5/6 ÷ 1/18 = 5/6 * 18 = 15
Thus, the answer is D.
4) A is 3, which means we substitute all the "a"s in the expression for 3. Thus we have:
99 - 7[tex]a^{2}[/tex]
99 - 7(3)^2
99 - 7(9)
99 - 63 = 36
Therefore, it is 36.
