Answer:
The coordinates of point S are (5, 9) will make line PQ // line RS ⇒ A
Step-by-step explanation:
Parallel lines have the same slopes
The slope of a line = Δy/Δx, where
Δ y is the change of yΔ x the change of xLet us first find the slope of the line PQ.
∵ P = (-2, -2) and Q = (0, 7)
∴ Δx = 0 - (-2) = 0 + 2 = 2
∴ Δy = 7 - (-2) = 7 + 2 = 9
∴ The slope of PQ = 9/2
∵ Line PQ // line RS
∴ The slope of line PQ = the slope of line RS
∴ The slope of line RS =9/2
∵ Point R = (3, 0) and point S = (x, y)
∵ The slope of line RS = 9/2
∵ The slope = Δy/Δx
∴ Δy/Δx = 9/2
→ That means Δy = 9 and Δx = 2
∵ Δy = y - 0
∵ Δy = 9
∴ 9 = y
∵ Δx = x - 3
∵ Δx = 2
∴ 2 = x - 3
→ Add 3 to both sides
∴ 2 + 3 = x - 3 + 3
∴ 5 = x
∴ The coordinates of point S are (5, 9) will make line PQ // line RS

PLS HURRY AND ANSWER I HAVE 10 minutes left
The answer is y = 12x - 24
Use the form y = mx + b
If the points are (2, 0) and (3, 12) the slope is 12 which gives us m.
Since every time you go backwards once it goes down 12, (1, -12) is a point and then (0, -24) is a point that shows us the y-intercept which gives us b.

hello
The Mulder Farm has 600 acres of land allotted for raising corn and wheat. The cost to cultivate corn is $40 per acre. The cost to cultivate wheat is $25 per acre. The Mulders have $18,000 available to cultivate these crops. How many acres each crop should the Mulders plant
Answer: Corn = 200 acres
Wheat= 400 acres
Step-by-step explanation:
Let the number of acres of corn = c
Let the number of acres of wheat = w
The Mulder Farm has 600 acres of land allotted for raising corn and wheat. This will be:
c + w = 600
c = 600 - w
Cultivation cost equals:
= 40c + 25w = 18000
Since c = 600 - w, we slot it into the equation
40c + 25w = 18000
40(600 - w) + 25w = 18000
24000 - 40w + 25w = 18000
Collect like terms
24000 - 18000 = 40w - 25w
6000 = 15w
w = 6000/15
w= 400
400 acres of wheat will be planted
Since c + w = 600
c = 600 - 400
c = 200
200 acres of corn should be planted
Find 18% of $25. Please i need help
Answer:
4.50 i think
Step-by-step explanation:
a product that normally costs $25 with a 18 percent discount will cost you $20.50, and you saved $4.50. You can also calculate how much you save by simply moving the period in 18.00 percent two spaces to the left, and then multiply the result by $25 as follows: $25 x . 18 = $4.50 savings.
Answer:
4.5
Step-by-step explanation:
you multiply 18 and 25 to get an answer of 450 then divided it by 100 to get 4.50
Which answer is an equation in point-slope form for the given point and slope?
Point: (5, 9); Slope: 2
Answer:
point slope form: y - y1 = m(x - x1)
m = slope, (x1, y1) is a point on the line
y - (-9) = 2(x - 1)
y + 9 = 2(x-1)

Help please. I'll give the Brainliest.
Answer:
Options 1,2,3 are correct statements
The first values in an ordered pair ( the coordinates) are the domain : ( -3,-2,-1,0,1)
The second values are the range : (-1,1,2,3,4,5)
One input should have only one output for a function.
But -1 input has 2 outputs: -1 and 3.
Thus, it is a relation and not a function.
Hope it helps :)

Step-by-step explanation:
8 taps can fill a tank in 27 min with the same rate of flow. If 3 taps go out of order how long will the remaining taps take to fill the tank
Answer:
pls 5 star
Step-by-step explanation:
8 taps can fill a tank in 27 minutes.
So,
1 tap can fill the same tank in time = 27 × 8 = 218 minutes
Therefore, 6 remaining taps can fill the same tank = 216/6
= 36 minutes
The remaining 6 taps will take 36 minutes to fill the same tank.

7. Here's how Mo solved the subtraction problem
635 - 813:
635
- 813
- 222
Mo did this by working from right to left, saying
5 – 3 = 2
3 - 1 = 2
6 - 8 = -2
a. Is Mo's answer right?
b. Solve
6(100) + 3(10) + 5(1)
- [8(100) + 1(10) + 3(1)]
by working with expanded forms. Discuss how
Mo's work compares with your work in expanded
forms.
Answer:
Mo's answer is wrong.
635 - 813
= -178
Step-by-step explanation:
a. Is Mo's answer right?
No, Mo's answer is incorrect
Mo did this by working from right to left, Just like Subtraction
• 3 - 5 =
We that 1 from the number in tens , add that to 3, making it 13
13 - 5 = 8
• 1 - 3 = 7
The one above becomes 0, because 1 was taken from it. We add 1 to 0, making it 10
10 - 3 = 7
• 8 - 6 = 1
The 8 above reduces to 7 because 1 has been taken from 8.
Hence: 7 - 6 = 1
635 - 813
= -178
The answer is minus 178 because, we are subtracting the bigger number form the smaller number.
b. Solve
6(100) + 3(10) + 5(1)
- [8(100) + 1(10) + 3(1)]
by working with expanded forms. Discuss how Mo's work compares with your work in expanded forms.
= -1(100) + 7(10) + 8(1)
i need help with this i am really bad at math
Answer:
You subtracted 25 from both sides.
Step-by-step explanation:
To move one part of the equation to the other side, you need to do the opposite. 25 is already negative(or being subtracted) so you need to add it to both sides to cancel it out on the left.
10x=-75+25
10x=-50
then divide both sides by 10
x=-5

Step-by-step explanation:
Anna is really involved in after school activities and is a part of the Drama club, as well as the Junior Optimist club. Every three days, there is a Drama club meeting, and every 8th day, she has Junior Optimist club meeting. Today she is scheduled to attend both meetings. How many days will it be until she will have both meetings on the same day again?
Answer:
The next time she will have both meetings on the same day again is 24 days time
Step-by-step explanation:
The given information are;
The frequency of the Junior Optimist club meeting = Every 3 days
The frequency of the Drama club meeting = Every 8th day
The club meeting Anna will attend today = Both meetings
The next time she will have both meetings on the same day again is given as follows;
The next time she will have both meetings on the same day again = The number of days the complete cycles of both meetings will coincide = The product of the cycles of both meetings
The next time she will have both meetings on the same day again = 8 × 3 = 24 days
The next time she will have both meetings on the same day again = 24 days time.
The side lengths of the rectangle are reduced by a scale factor of 1/4. (The side lengths are 16 and 36in) What is the area of the new rectangle?
Answer:
36 i think
Step-by-step explanation:
16 divided by 4 is 4
36 divided by 4 is 9
4*9=36
Answer:
324 square inches
Step-by-step explanation:
1/4 of 16 = 4
16-4 = 12
1/4 of 36 = 9
36-9 = 27
A= l*w
A= 27 x 12
A= 324 square inches

Anthony writes a numerical expression 2+10x3-2 and says that the expression has a value of 34. Is Anthony correct? Explain your answer.
Answer:
he is incorrect
Step-by-step explanation:
He is incorrect because 10 times 3 is 30, plus-minus 2 which is 30. So instead of 34, it is 30. or you can say Anthony is wrong. Following the order of operations, you would do the 10*3 first. Then, you would take the 30, and finish the equation from left to right. So you would add 2 to make it 32 and then subtract 2 to make it 30 again. So your final answer is 30, not 34. So Anthony is wrong.

which could be the side lengths of a right triangle?
Answer:
B
Step-by-step explanation:
90+45+45=180
All triangles equal 180.
Its B because if one angle is 90° then the other angles will equal each other. It cant be 60° and 30° because they dont equal, so your final answer is B.
Hope this Helps!!! :)

Step-by-step explanation:
Given
4(x + 2) < - [tex]\frac{1}{2}[/tex] (4x - 4) ← distribute parenthesis on both sides )
4x + 8 < - 2x + 2 ( add 2x to both sides )
6x + 8 < 2 ( subtract 8 from 2 )
6x < - 6 ( divide both sides by 6 )
x < - 1
x ∈ (- ∞, - 1 ) ← in interval notation
