Answer: y+5 = 9/8(x-9)
Step-by-step explanation: Point-slope form is written in y-y1 = m(x-x1) so when you put in (9,-5) in the y1 and x1 spots and substitute the slope 9/8 in for m you get the point-slope form.
Answer:
[tex]y+5=\frac{9}{8}(x-9)[/tex]
Step-by-step explanation:
Point slope form is: [tex]y-y_1=m(x-x_1)[/tex]
'm' - slope
(x1, y1) - point
We are given the slope of 9/8 and the point of (9, -5).
Replace 'm', 'x1', and 'y1' with the appropriate values.
[tex]y-y_1=m(x-x_1)\rightarrow\boxed{y+5=\frac{9}{8}(x-9)}[/tex]

If the m∠SRW = 85°, what are the measures of ∠VRU and ∠URW?
Answer:
∠VRU = 80°
∠URW = 15°
Step-by-step explanation:
Given that,
∠TRV = ∠SRW ( vertical opposite angle)
2x + 15 = 85
2x = 70
x = 35
So,
∠VRU = 2x + 10
∠VRU = (2×35) + 10
∠VRU = 70 + 10
∠VRU = 80°
∠URW = 180 - ∠VRU - ∠SRW
∠URW = 180 - 85 - 80
∠URW = 15°
Answer:
80 and 15

There are 80 pupils in Jaydon's year group.
30% walk to school. 15% cycle to school. The rest get a bus.
How many pupils walk to school?
go
Show me the answer
How many pupils get the bus?
go
Answer:
walk is 24 people
bus is 44 people
Step-by-step explanation:
100% is 80
30% walk
15% bike
55% bus
work out 30%
so 50% is 40
25% is 20 (dived by 2)
5% is 4 (divide 50 by 10)
30% is 24
for bus do 50% is 40
5% is 4
55% is 44 (add)
Abcd is a rectangle.
Mr. Mole left his burrow and started digging his way down.
A represents Mr. Mole's altitude relative to the ground (in meters) after t minutes.
A= -2.3t – 7
How fast did Mr. Mole descend?
Answer:
He's descending at a pace of 2.3 meters per minute.
Step-by-step explanation:
This is because the equation shows us the slope or the speed he's going at.
A= -2.3t - 7
A= Altitude
-2.3 = Slope
- 7 is his starting altitude in meters
But every minute, t, he is going down 2.3 meters. It's easier to think about if you consider, A = y, and, t = x. Now you have the equation, y = -2.3x - 7.
And you graph it to see the progression in slope.

Allyson completed the division below.
9 StartLongDivisionSymbol 187.2 EndLongDivisionSymbol minus 18 = 07 minus 0 = 72. 72 minus 72 = a remainder of 0 and a quotient of 20.8.
What is Allyson’s error?
She included a 0 in the quotient that does not belong.
She multiplied the dividend by 100 instead of 10.
She should have multiplied both numbers by 100.
She did not subtract correctly in one of the steps.

The number of milligrams of a certain medicine a veterinarian gives to a dog varies directly with the weight of the dog. If the veterinarian gives a 30-pound dog Three-fifths milligram of the medicine, which equation relates the weight, w, and the dosage, d? d = StartFraction 1 Over 50 EndFraction w d = three-fifths w d = 18 w d = 50 w
Answer:
Step-by-step explanation:
A direct variation equation is of the form
y = kx,
where, in words, it reads "y varies directly with x" or "y varies directly as x". In order to use this as a model, we have to have enough information to solve for k, the constant of variation. The constant of variation is kind of like the slope in a straight line. It rises or falls at a steady level; it is the rate of change.
We have that a vet gives a dose of three-fifths mg to a 30 pound dog. If the dose varies directly with the weight of the dog, then our equation is
d = kw and we need to find k in order to have the model for dosing the animals.
[tex]\frac{3}{5} =k(30)[/tex]
Divide both sides by 1/30 to get k alone.
[tex](\frac{1}{30})(\frac{3}{5})=k[/tex] and
[tex]k=\frac{1}{50}[/tex]
Our model then is
[tex]d=\frac{1}{50}w[/tex]
This means that for every pound of weight, the dog will get one-fiftieth of a mg of medicine.

(25 POINTS) Write the inequality of the following graph?
Answer:
f(x) > -x + 2
Step-by-step explanation:
First I found the equation of the line.
The y intercept is at 2 so I know to add 2 at the end
The slope is -1 since it is going downwards
Since the top side is shaded, that represents greater than, if it was shaded downwards, it would be less than
Putting all that together, the equation is f(x) > -x + 2
Solve the pair of simultaneous equation 4x+6y=21 and 7x-3y=3
Answer:
X=1.5,y=2.5
Step-by-step explanation:
By elimination method
U have to make either x or y values equal and then eliminate it
The y values have a common value 12
By multiplying 6×2 and 3×4
2(4x+6y)=(21)2
4(7x-3y)=(3)4
8x+12y=42
+
28x-12y=12
36x=54
X=54/36=1.5
Substitute x with 1.5
Y=2.5
The solution to the simultaneous equation is x = 3/2 and y = 5/2.
What is a system of equations?A system having more than two equations is known as a system of equations
The given pair of equations is:
4x + 6y = 21 (1)
7x - 3y = 3 (2)
Multiply equation (2) by 2 and add into equation (1):
4x + 6y + 14x -6y = 21 + 6
18x = 27
x = 27/18
x = 3/2
Substitute x = 3/2 into equation (1):
4(3/2) + 6y = 21
6 + 6y = 21
6y = 15
y = 15/6
y = 5/2
Hence, the solution to the simultaneous equation is x = 3/2 and y = 5/2.

The answer is : 0.12 x 600 = 72 or the equivalent : 600 x 12/100 = 72
Your list of possible answers ended up a bit scrambled for me to identify which one it is.
Step-by-step explanation:
The number of black and white pictures can be obtained by multiplying the total number of pictures taken (600) by the decimal form of 12% = 12/100 = 0.12. That is:
Number of B&W pictures = 0.12 x 600 = 72

the radius of wheel of a bicycle is 40 cm. taking pie =3.14, a)find tthe circumference of the wheel.b) find the distance covered by the bicycle in 200 complete revolution of the wheel.please ans this question. i beg you
Answer:
a)=251.2 cm b)=50240 cm
Step-by-step explanation:
a) The formula for calculating the circumference of a circle is c=d*pie, where D is the diameter of the circle.
Therefore, C = 2 * 40 * 3.14 = 251.2 cm
b) The distance covered by 200 revolutions of the wheel is 200 times the circumference, 200*251.2=50240 cm.So to think about this we can assume that there is a point A on the wheel, the distance that point A travels when it rotates 200 times.

The perimeters of the square and the regular pentagon are equal. A square with side lengths of 3x + 3. A pentagon with side lengths of x + 8.
Answer:
60
Step-by-step explanation:
Since the perimeters are equal then:
(3x + 3) * 4 = (x + 8) * 5
12x + 12 = 5x + 40
7x = 28
x =4
Perimeter of square = (3*4 + 3) * 4 =
(12 + 3) * 4 = 60
Perimeter of pentagon = (4 + 8) * 5 =
(12) * 5 = 60
The answer is 60
