Answer:
[tex]y-(9)=(-8)(x-8)\\[/tex]
Step-by-step explanation:
[tex](x_1, y_1) = (8, 9)\\(x_2, y_2) = (9,1)\\[/tex]
Step one: Find the slope (m)
[tex]slope=m=\frac{rise}{run} =\frac{y_2-y_1}{x_2-x_1} = \frac{1-9}{9-8} =\frac{-8}{1} =-8[/tex]
Step two: Plug your known values into the point-slope equation
[tex]m=-8\\y_1=9\\x_1=8\\[/tex]
Point-slope form is [tex]y-y_1=m(x-x_1)[/tex]
[tex]y-(9)=(-8)(x-8)\\[/tex]
If you want to convert point-slope form to general form, isolate for y.
[tex]y-9=-8x+64\\y=-8x+73[/tex]

sewing a border of ribbon onto her rectangular picnic blanket. The long side of the blanket is 70cm and the short side is 40cm. How much ribbon will she need?
Answer:
[tex]220[/tex] cm
Step-by-step explanation:
We need to find the perimeter of the rectangular blanket in this case because a border is being sewn onto the blanket. The perimeter of a rectangle can be calculated by multiplying the sum of the rectangle's length and width by 2. As an algebraic expression, that would be [tex]2(l+w)[/tex], where [tex]l[/tex] is the rectangle's length and [tex]w[/tex] is the rectangle's width. We are given that [tex]l=70[/tex] and [tex]w=40[/tex]. Therefore, [tex]2(70+40)=2*110=220[/tex] cm of ribbon will be needed. Hope this helps!

13/11,24/13,11/13,11/24
Answer:
65:55, 55:65, 55:120
Step-by-step explanation:
Fiberglass boats are = 65 because 120-55=65
Fiberglass to wood means that there is a 65:55 ratio because there are 65 fiberglass boats and 55 wood boats
wood to other, this is kind of a trick question, but its 55:65 because there are 65 other boats and 55 wooden boats
wood to total, this is 55:120 there are 55 wood boats and 120 total boats.
Reuben hires a car. It costs £150, plus 85p for each mile he travels. When Reuben hires the car, its mileage is 27612 miles. When Reuben returns the car, its mileage is 28361 miles. How much did Reuben pay to hire the car?
Answer:
Cost of hiring a car = £63,815
Step-by-step explanation:
Cost of hiring a car = 150 + 85p
When Reuben hires the car, its mileage is 27612 miles. When Reuben returns the car, its mileage is 28361 miles.
Number of miles Reuben travelled = 28,361 miles - 27,612 miles
= 749 miles
Cost of hiring a car = 150 + 85p
= 150 + 85(749)
= 150 + 63,665
= 63,815
Cost of hiring a car = £63,815

Find the next three terms in the sequence below.
[tex]\frac{21}{2} , \frac{19}{3}, \frac{17}{4} , 3, . . .[/tex]
Answer: 13/6
Step-by-step explanation:
Based upon the previous sequence.
1.there is a constant decrease of two in the numerator
2. There is a constant increase of one in the denominator
to find the fourth number in the sequence I used One of the numbers from the previous to determine the answer.
17/4 — —> then I followed the pattern and determine what fraction 3 was . . before it was converted into a whole number.
which would be 15/5 —> Now considering equations that are written like this also mean division, because in this case division is possible the answer would be 3, which would make the whole number 3 instead of 15/3. considering it was an improper fraction.
____________________________________________________________
Now If 15/5 wasn’t converted into 3, The answer to the sequence would be 13/6. If you follow the pattern like I said before there is a certain amount of increase and decrease so 13/6 will be your answer. The only reason is not a whole number because 13 can’t be divided by six to get a whole number.
3) Barbara can walk 3,200 meters in 24 minutes. How far can she walk in 3
minutes? (journal pg. 49)
+
320 meters
400 meters
640 meters
720 meters
Answer:
400 meters
Step-by-step explanation:
We know that Barbara can walk 3,200 meters in 24 minutes . And are being asked to see how far she can walk in 3 minutes.
Create the unit rate. Since Barbara can walk 3,200 in 24 minutes and we're trying to figure out how many meters she walks in 3 mintues, make the meters "M"
[tex]\frac{3200}{24} = \frac{M}{3}[/tex]
Let's do something that can make 24 mintues go to 3 minutes, this would be dividing 24 by 8, do the same with the numerator :
[tex]\frac{3200/8}{24/8}[/tex]
[tex]\frac{400}{3}[/tex]
Therefore Barbara can walk 400 meters in 3 minutes,

Which relationships describe angles 1 and 2?

b. supplementary angles
c. complementary angles
d. vertical angles
In JKL, k=4.1 cm,j=3.8 cm and angle J=Q3^ Find all possible values of angle K , to the nearest inch of a degree .
Answer:
74.0°
Step-by-step explanation:
In triangle JKL, k = 4.1 cm, j = 3.8 cm and ∠J=63°. Find all possible values of angle K, to the nearest 10th of a degree
Solution:
A triangle is a polygon with three sides and three angles. Types of triangles are right angled triangle, scalene triangle, equilateral triangle and isosceles triangle.
Given a triangle with angles A, B, C and the corresponding sides opposite to the angles as a, b, c. Sine rule states that for the triangle, the following holds:
[tex]\frac{a}{sin(A)}=\frac{b}{sin(B)}=\frac{c}{sin(C)}[/tex]
In triangle JKL, k=4.1 cm, j=3.8 cm and angle J=63°.
Using sine rule, we can find ∠K:
[tex]\frac{k}{sin(K)}=\frac{j}{sin(J)} \\\\\frac{4.1}{sin(K)}=\frac{3.8}{sin(63)} \\\\sin(K)=\frac{4.1*sin(63)}{3.8}\\\\sin(K)=0.9613\\\\K=sin^{-1} (0.9613)\\\\K=74.0^o \\[/tex]

A scooter tracked 30 feet in 2 seconds at a constant speed what is the speed of the scooter in feet per second
please help i cant figure this out :/
Answer:
6,15
Step-by-step explanation:
A dilation is the changing of a size. A scale factor is a proportional number that tells us how much we change a shape.
If the scale factor is over 1, the new image will stretch.
If the scale factor is under 1, the new image will shrink
Since we are asked to find A' (which is prime notation) meaning that we are asked to find the coordinates where A' is at on the new image.
Since the scale factor is 3,
3 is greater than 1 so it will stretch.
Now, multiply 3 to each number
to find it new location.
[tex] \frac{2}{5} \times \frac{3}{3} = \frac{6}{15} [/tex]
So the coordinates are at 6,15
Answer:
I'm pretty sure you multiply each number in (2,5) by the 3 to get new coordinates of (6,15)
that's the only answer that could fit :)

What are some rules of exponents?Some common rules of exponents are
xᵃ×xᵇ = xᵃ⁺ᵇ.
xᵃ/xᵇ = xᵃ⁻ᵇ.
Addition and subtraction of exponents are only possible for the same base value and when the base is different and both have the same exponent we just multiply the bases and write the exponent.
We also know that a multiplied by a 'n' number of times can be written
as aⁿ.
Now, 2 to the power of 6 in exponent form is 2⁶ which states 2 is multiplied by 2, 6 times.
Therefore, From the given options the expression that is equivalent to
