equation: f(x) = 3/2x - 3
the line is linear and proportional
the line is linear because it has a steady rate of change, which is 3/2, and the equation is in the y=mx+b form. it is also proportional because as the x value increases, the y value also increases.
slope: 3/2
the y intercept is -3
John has three bags, each containing x counters. He removes one country from each of his bags. Write an expression for the total number of counters in John's bag now
Answer: 3x - 3
Step-by-step explanation:
Each bag contained x counters and there are 3 bags.
He removes one counter from each of the 3 bags so the expression for the counters in each bag is now;
= x - 1
As there are 3 bags, the expression is;
= 3 * ( x - 1)
= 3x - 3

Use quadratic regression to find the equation for the parabola going through these three points (-7,134)(-3, 10)(5,50)
Please help me! Thanks
Answer:
Step-by-step explanation:
y = ax² + bx + c
a( - 7)² + b( - 7) + c = 134 ⇔ 49a - 7b + c = 134 ......... (1)
a( - 3)² + b( - 3) + c = 10 ⇔ 9a - 3b + c = 10 ......... (2)
a(5)² + b(5) + c = 50 ⇔ 25a + 5b + c = 50 ......... (3)
(1) - (2)
40a - 4b = 124 ⇔ 10a - b = 31 ........... (4)
(3) - (2)
16a + 8b = 40 ⇔ 2a + b = 5 ........... (5)
(4) + (5)
12a = 36 ⇒ a = 3
2(3) + b = 5 ⇒ b = - 1
9(3) - 3( - 1) + c = 10 ⇒ c = - 20
y = 3x² - x - 20
y = [ 3 ] x² + [ - 1 ] x + [ - 20 ]

if the second term of a geometric series is 48 and its fifth term is 6 then find the sum of its first term 6 terms
Answer:
The answer is 189.
Step-by-step explanation:
This geometric sequence is actually just a division of 2 for every term downwards. Therefore, we can see the first term is [tex]48 \cdot 2[/tex] which is 96. Hence, we can work our way down from there:
List:
First term: 96
Second term: 48
Third term: 24
Fourth term: 12
Fifth term: 6
Sixth term: 3
Now, all we have to do is to add all the first 6 terms together to get:
[tex]96 + 48 + 24 + 12 + 6 + 3[/tex]
[tex]= 189[/tex]
The answer is 189.
Hope this helped!

The points (-5, -22) and (4, r) lie on a line with slope 3. Find the missing coordinate r.
Step-by-step explanation:
here,
x1= -5. x2=4
y1= -22. y2=r
slope(m)=3
now we have,
m=(y2-y1)/(x2-x1)
or,3=(r-(-22))/(4-(-5))
or,3=(r+22)/(4+5)
or,3=(r+22)/9
or,27=r+22
or,r=27-22
or,r=5
Dawn is y years old.
Rashid is three times as old as Dawn.
Hugo is seven years younger than Dawn.
The total of Dawn's age, Rashid's age and Hugo's age is T years.
a) Find a formula for T in terms of y.
Answer:
T= y+ 3y-7
Step-by-step explanation
I'm pretty sure you can also write T= 4y-7 as a simplified form of the equation
The formula for T in terms of y can be written as;
T= y+ 3y -7
What is an equation?An equation is an expression that shows the relationship between two or more numbers and variables.
A mathematical equation is a statement with two equal sides and an equal sign in between. An equation is, for instance, 4 + 6 = 10. Both 4 + 6 and 10 can be seen on the left and right sides of the equal sign, respectively.
Given that Dawn is y years old.
So, Rashid is three times as old as Dawn means R = 3y
Hugo is seven years younger than Dawn means H = y - 7
The total of Dawn's age, Rashid's age and Hugo's age is T years.
We can also write T= 4y-7 as a simplified form of the equation

Find the surface are of a cylinder with a base diameter of 10m and a height of 7m. WLL GIVE BRAINLIEST IF U HAVE AN ACCURATE EXPLANATION!
Answer:
hi
Step-by-step explanation:
im adding an answer so u can giveee the guy brailiestz
Answer:
376.8 m²
Step-by-step explanation:
The formula for finding the surface area of a cylinder is SA=2πr²+2πrh, where r is the radius of the base and h is the height of the cylinder. Using the diameter of the base, we can first calculate that the radius of the base is 10/2=5 meters. Then, we can plug our values into the equation.
SA=2πr²+2πrh
SA=2π(5)²+2π(5)(7)
SA=2π(25)+2π(35)
SA=50π+70π
SA=120π
Because the question asks us to use 3.14 for π, we plug that into our equation.
SA=120(3.14)
SA=376.8 m²

Answer:
no solution
Step-by-step explanation:
Given
- 5 | x + 1 | = 10 ( divide both sides by - 5 )
| x + 1 | = - 2
To have a solution the right side of the equation must be positive or zero
No absolute value can have a negative solution
Thus the equation has no solution

Answer:
[tex]\boxed {\boxed {\sf 53}}[/tex]
Step-by-step explanation:
This is a right triangle, which we know because of the little square in the corner.
We can use the Pythagorean Theorem:
[tex]a^2+b^2=c^2[/tex]
where a and b are the legs and c is the hypotenuse.
In this triangle, 28 and 45 are the legs, because they make up the right angle. The unknown side is the hypotenuse, because it is opposite the right angle.
[tex]a=28 \\b=45 \\[/tex]
[tex](28)^2+(45)^2=c^2[/tex]
Solve the exponents.
(28)²= 28*28= 784[tex]784+(45)^2=c^2[/tex]
(45)²=45*45=2025[tex]784+2025=c^2[/tex]
Add the two numbers.
[tex]2809=c^2[/tex]
Solve for c by isolating it on one side of the equation. c is being squared. The Inverse of a square is the square root. Take the square root of both sides of the equation.
[tex]\sqrt{2809} =\sqrt{c^2}[/tex]
[tex]\sqrt{2809} = c[/tex]
[tex]53=c[/tex]
The third side and hypotenuse of the triangle is 53
[tex]\pink{\sf Third \: side \: of \: the \: triangle = 53}[/tex]
Solution :As, the given triangle is a right angled triangle,
Hence, We can use the Pythagoras' Theorem,
[tex]\star\:{\boxed{\sf{\pink {H^{2} = B^{2} + P^{2}}}}}[/tex]
Here,
H = Hypotenuse of triangleB = Base of triangle P = Perpendicular of triangleIn given triangle,
Base = 45 Perpendicular = 28 Hypotenuse = ?Now, by Pythagoras' theorem,
[tex]\star\:{\boxed{\sf{\pink {H^{2} = B^{2} + P^{2}}}}}[/tex]
[tex] \sf : \implies H^{2} = (45)^{2} + (28)^{2}[/tex]
[tex] \sf : \implies H^{2} = 45 \times 45 + 28 \times 28[/tex]
[tex] \sf : \implies H^{2} = 2025 + 784[/tex]
[tex] \sf : \implies H^{2} = 2809[/tex]
By squaring both sides :
[tex] \sf \sqrt{H^{2}} = \sqrt{2809}[/tex]
[tex] \sf : \implies H^{2} = \sqrt{2809}[/tex]
[tex] \sf : \implies H^{2} = \sqrt{(53)^{2}}[/tex]

Pentagon PENTA has coordinates P(0,0), E (4,4), N (8,4), T ( 8,-4), and A (4,-4) and is dilated at the origin with a scale factor of 3/4. Select all that are coordinates of P’E’N’T’A?
Answer:
5
Step-by-step explanation:
because thats the answer
Answer:
P'(0,0), E' (3,3), N'(6,3), T'(6,-3), A'(3,-3)
Step-by-step explanation:
1.The dilation is by a scale factor of 3/4 meaning it's less than one, meaning the image will get smaller.
2.To find the new coordinates, multiply 3/4 by each number in the coordinate pair. For example 4x3/4 is 3 making (4,4) (3,3).
