Answer:
my guess would have to be
A. slope= 4
B. y-intercept= 23/3 or 7 2/3(simplified)
Step-by-step explanation:
im not sure how accurate my answer would be but what i did was put the equation in slope intercept form and added 6 for the dilatation to all factors of the equation.
The slope is 2/3.
The y-intercept is -5/3.
What is an equation of a line?The equation of a line is given by:
y = mx + c
where m is the slope of the line and c is the y-intercept.
Example:
The slope of the line y = 2x + 3 is 2.
The slope of a line that passes through (1, 2) and (2, 3) is 1.
We have,
The equation of the line.
6x - 3y = 5
Now,
To apply a dilation with a scale factor of 6 centered at the origin.
We multiply both sides by 6.
So,
6 (6x - 3y) = 6 x 5
Now,
Simplifying.
36x - 18y = 30
Dividing both sides by 18.
2x - y = 30/18
2x - y = 5/3
Now,
Writing in slope-intercept form.
y = mx + c
So,
y = 2x - 5/3
This means,
Slope m = 2
y-intercept c = -5/3
Thus,
The slope is 2/3.
The y-intercept is -5/3.

1. Quadrilateral ABCD has AB = x+3 and CD= 5x –7. What is the length of x
for which the quadrilateral is a parallelogram?
Answer:
x = 2.5
Step-by-step explanation:
since it's a parallelogram, AB = CD so:
x + 3 = 5x - 7
subtract x from each side of the equation:
3 = 4x - 7
add 7 to each side:
4x = 10
divide both sides by 4:
x = 2.5

1. The diameter of a circle is 8. what is the radius?
Answer:
Radius = 4
Step-by-step explanation:
r = d/2
r = 8/2
r = 4
Answer:
4
Step-by-step explanation:
The diameter of a circle is the length of a straight line from two opposite points on the circle. The radius is the length of a straight line from the middle to a point on the circle. This means that the diameter must be double the radius. So to find the radius, divide the diameter by 2. Since 8/2=4, the radius is 4.

factoring method..
f (x) = - x² + 12x - 20
= - x² + 10x + 2x - 20
= - x( x - 10 ) + 2( x - 10 )

Triangle XYZ has vertices X(1, –1), Y(3, 4), and Z(5, –1). Nikko rotated the triangle 90° counterclockwise about the origin. What is the correct set of image points for triangle X’Y’Z’?
X’(1, 1), Y’(-4, 3), Z’(1, 5)
X’(1, 1), Y’(–3, –4), Z’(–1, –5)
X’(–1, 1), Y’(–3, –4), Z’(–5, 1)
X’(–1, –1),Y’(4, –3), Z’(–1, –5)
Answer:
When a figure is rotated counterclockwise about the origin, its original coordinates of point P (x,y) will now be positioned as P' (-y,x).
X (1,-1) --> X' (1,1)
Y (3,4) --> Y' (-4,3)
Z (5,-1) --> Z' (1,5)
The correct set of image points for triangle X'Y'Z' is X'(1,1), Y'(-4,3), and Z'(1,5).
Step-by-step explanation:
Triangle XYZ is rotated 90° counterclockwise, the new coordinate is X'(1, 1), Y'(-4, 4) and Z'(1, -5)
TransformationTransformation is the movement of a point from its initial location to a new location. Types of transformation are translation, reflection, rotation and dilation.
If a point A(x, y) is rotated 90° counterclockwise the new point is A'(-y, x).

4. Jean and Mark are going to fill a pool with 2 different sized hoses. Jean can fill the pool in 4 hours, while Mark can complete it in 6 hours. Their supervisor thinks that the job will take 5 hours to
complete if they work together. Explain each step in solving this equation, and determine if the supervisor is correct or not.
Answer:
2.4 hours.
Step-by-step explanation:
Remark
The supervisor is not quite correct. The correct answer must be lower than the lowest number, otherwise you are taking out what the person with the narrower hose must be taking out what the other person is putting in.
Equation
Let x = the amount of time needed for him to fill the pool
Let y = the amount of time needed for the second person to fill the pool
Let z = the amount of time needed for both to fill the pool.
1/x + 1/ y = 1/z
1/4 + 1/6 = 1/z The common denominator is 12
3/12 + 2/12 = 1/z
5/12 = 1/z Cross multiply
5z = 12 * 1 Divide by 5
z = 12/5
z = 2 2/5
z = 2.4 hours

The correct option is (4).
What is Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides. LHS = RHS is a common mathematical formula.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given:
If Jeff drives 200 miles per hour in his race car.
So, if we denote the distance by y and time by x then relation is
y = 200x
For x = 0
y=0
and, x= 2
y= 400
and, x= 8
y= 1600
and, x= 5
y = 1000
Hence, the point not on the graph is (5, 1200)

A bag contains: • 2 white marbles • 3 brown marbles • 4 purple marbles • 6 orange marbles A marble will be drawn from the bag and replaced 75 times. What is a reasonable prediction for the number of times a brown or purple marble will be drawn?
Answer:
45
Step-by-step explanation:
There are 14 total marbles. The probability of drawing a yellow marble on the first draw is 3/14. Given replacement, the probability on the second draw is the same as on the first draw, so the probability of black marble on the second draw is 6/14. The probability of drawing first a yellow marble then a black marble is 3/14 * 6/14 = 18/196.
