Answer:
The coordinates of the image of point A(3,9) for dilation with the scale factor of 2/3 will be: A'(2, 6)
Step-by-step explanation:
Given the point A with the vertices (3, 9) i.e. A(3,9)
As we know that If the scale factor is between 0 and 1, the image gets shrunk.
In order to dilation with a scale factor of 2/3, just multiply the x and y coordinates of the original point (3, 9) by 2/3.
i.e.
(x, y) → (2/3 x, 2/3 y)
so, the coordinates of the image of point A(3,9) for dilation with the scale factor of 2/3 will be:
A (x, y) → (2/3 x, 2/3 y) = A (2/3 (3), 2/3 (9)) = A'(2, 6)
Therefore, the coordinates of the image of point A(3,9) for dilation with the scale factor of 2/3 will be: A'(2, 6)

What is the "c" called in phythagorean theorem
Answer: The Pythagorean theorem is used for right triangles. "c" = the hypotenuse, this is the longest side of the triangle and is always opposite the 90 degree angle. The values of "a" and "b" are the other 2 sides.
Step-by-step explanation:

The cost of 3 pounds of grapes is $6.57. What is the constant of proportionality that relates the cost in dollars, y, to the number of pounds of grapes, x?
Answer:
$2.19
Step-by-step explanation:
Given that :
Cost of 3 pounds of grape = $6.57
Cost in dollars = y ; number of pounds = x
Cost in dollars α number of pounds
Cost in dollars = k * number of pounds
k = constant of proportionality
$6.57 = k * 3
$6.57 = 3k
Divide both sides by 3
6.57 / 3 = 3k/ 3
2.19 = k
k = $2.19
Fred is playing tennis. For every 2 of his serves that land in, 3 serves land out. If he hit 28 serves in, how many serves landed out?
Answer:
the answer is 56.
Step-by-step explanation:
2 for every 4 = 1 for every two, so 28 multiplied by two.

x pounds of Repperts chocolate valued at $3.50 per pound is mixed with y pounds of Godiva
chocolate valued at $4.30 per pound to produce 10 pounds of a mixture selling for $39. Find x
and y, the number of pounds of each type of chocolate. write two equations and solve using elimination
!!!!PLEASE HELP!!!!
Answer:
5 pounds eachStep-by-step explanation:
Required equations:
x + y = 103.50x + 4.30y = 39Substitute x in the second equation:
x = 10 - ySolve for y:
3.5(10 - y) + 4.3y = 3935 - 3.5y + 4.3y = 390.8y = 4y = 4/0.8y = 5Then
x = 10 - 5 = 55 pounds each

5x+18=7x-6 what’s the answer?
Answer:
x = 12
General Formulas and Concepts:
Pre-Algebra
Order of Operations: BPEMDASEquality PropertiesStep-by-step explanation:
Step 1: Define equation
5x + 18 = 7x - 6
Step 2: Solve for x
Subtract 5x on both sides: 18 = 2x - 6Add 6 to both sides: 24 = 2xDivide both sides by 2: 12 = xRewrite: x = 12Step 3: Check
Plug in x to verify it's a solution.
Substitute: 5(12) + 18 = 7(12) - 6Multiply: 60 + 18 = 84 - 6Add/Subtract: 78 = 78And we have our final answer!
Write the ratio as a fraction in simplest form, with whole numbers in the numerator and denominator.

b) Factorise
Factorise y2 + 2y - 24
Answer:
(y + 6)(y - 4)
Step-by-step explanation:
Factor the following:
[tex] \longrightarrow [/tex] y² + 2y - 24
The factors of -24 that sum to 2 are 6 and -4.
So,
[tex] \longrightarrow [/tex] y² + (6 - 4)y -24
[tex] \longrightarrow [/tex] y² + 6y - 4y - 24
[tex] \longrightarrow [/tex] y(y + 6) - 4(y + 6)
[tex] \longrightarrow [/tex] (y + 6)(y - 4)
Answer:
( y-4) ( y+6)
Step-by-step explanation:
= y^2 + ( 6 - 4)y - 24
= y^2 + 6y - 4y - 24
= y( y + 6) - 4(y + 6)
= ( y - 4 ) ( y + 6)

HELLO HUMANS! QUICK QUESTION. WILL MARK AS BRAINLIEST!
How do you solve for the slope of a graph that isn't straight? How would I solve the slope for this?
9514 1404 393
Answer:
use the slope formula
Step-by-step explanation:
Usually, you are asked for an average slope over some interval. The slope is calculated on that interval the same as it would be if you were given two points, one at each end of the interval.
m = (y2 -y1)/(x2 -x1)
For example, if you wanted to know the slope on the interval [1, 2] hours, the points you would use would be ...
(hours, miles) = (1, 25) and (2, 75)
The corresponding slope on that interval is ...
m = (75 -25)/(2 -1) = 50 . . . . miles per hour
__
You can identify four (4) regions on this graph in which the slope is constant:
(0, 1) . . . slope is 25 mph
(1, 2) . . . slope is 50 mph, as computed above
(2, 3) . . . slope is 0 (the rider has stopped)
(3, 5) . . . slope is 25 mph
Over different intervals, you need to identify the points involved and use the formula to compute the average slope.
