Start with y = |x|. Plot the vertex at (0, 0). Draw the line y = x in the first quadrant, not below y = 0, for positive x values. Draw the line y = -x in the second quadrant, not below y = 0, for negative x values.
This gives you a v-shaped graph with vertex at (0, 0).
Going back to the given problem:
Reflect the graph of y = |x| in the x-axis, so that the vertex is now (0, 0) and the v-shape opens down.
Finally, translate this resulting graph upward by four units.

by what rational no. should -7/85 be multiplied to obtain 1/17?
Answer:
-1/10115
Step-by-step explanation:
Let x be the rational number.
-7/85 × x = 1/17
x = 1/17 ÷ -7/85
x = 1/(17 × -7 × 85)
x = 1/(-10115)
x = -1/10115
The rational number is -1/10115.
Answer:
- 5/7
Step-by-step explanation:
-7/85*x= 1/17
x= 1/17 ÷ (-7/85)
x= - 1/17 × 85/7
x= - 5/7
Given a graph for the transformation of f(x) in the format g(x) = f(kx), determine the k value. two parabolas open up with f of x passing through 8 comma 6 and g of x passing through 2 comma 6 k = −4 k = negative one fourth k = one fourth k = 4
Here we have a problem of transformations, particularly, horizontal dilations.
We will find that the correct option is k = 4.
We have two functions:
f(x) and g(x) = f(k*x)
We know that:
f(x) passes through the point (8, 6)
This means that:
f(8) = 6
And we know that g(x) passes through (2, 6)
this means that:
g(2) = 6
Using these two and the representation of g(x), we can see that:
g(2) = f(k2) = 6
and we knew that f(8) = 6
then
k2 = 8
k = 8/2 = 4
Then the value of k is 4.

A bag contains 4 red marbles, 6
white marbles, and 5 blue marbles.
If a marble is selected from the
bag, what is the probability that the
marble is not red?
Answer:
the probability that the marble is NOT red is 1 - 4/15, or 11/15
Step-by-step explanation:
Find the probability that the marble IS red: 4/(4 + 6 + 5) = 4/15
Then the probability that the marble is NOT red is 1 - 4/15, or 11/15
the probability that the marble selected from the bag is not red is 11/15 or approximately 0.7333.
To calculate the probability that a marble selected from the bag is not red, we need to determine the total number of marbles that are not red and divide it by the total number of marbles in the bag.
The bag contains 4 red marbles, 6 white marbles, and 5 blue marbles.
The total number of marbles that are not red is the sum of the white and blue marbles, which is 6 + 5 = 11.
The total number of marbles in the bag is the sum of all three colors, which is 4 + 6 + 5 = 15.
Therefore, the probability that the marble selected is not red is:
Probability = Number of marbles not red / Total number of marbles
Probability = 11 / 15
The probability is 11/15, which can also be expressed as approximately 0.7333 or 73.33% (rounded to two decimal places).
So, the probability that the marble selected from the bag is not red is 11/15 or approximately 0.7333.

The answer is a = 3√2. The explanation and steps of how I got the answer is in the image below.
P(2, 2), Q(1, -3), R(-4, 2), S(-3, 7) Using the information above, answer the following questions. Find the length of RS Find the length of SP Find the length of PQ Find the length of RQ Use this information to determine if the quadrilateral a parallelogram.
Answer:
Yes the Quadrilateral is a Parallelogram.
Step-by-step explanation:
A parallelogram can be defined as a quadrilateral i.e a geometric shape with four sides that has opposite sides parallel and equal in length.
From the question, we are given the following points
P(2, 2), Q(1, -3), R(-4, 2), S(-3, 7)
Given points: (x1, y1) and (x2, y2)
The formula would be
√(x2 - x1)² +(y2 - y1)²
a) P(2, 2), Q(1, -3)
Length PQ = √(1 - 2)² +(-3 - 2)² = √-1² + -5² = √26
b) R(-4, 2), S(-3, 7)
Length RS = √(-3 - (-4))² + (7 - 2) ² = √ 1² + 5² = √26
c) R(-4, 2), Q(1, -3)
Length RQ = √(1 - (-4))² + (-3 - 2)² = √5² + 5² = √(25 + 25) = √50
d) S(-3, 7), P(2, 2)
Length SP = √(2 - (-3))² + (2 - 7)² = √5² +(-5)² = √(25 + 25) = √50
From the above solution, we can see that
Length PQ = Length RS
Length RQ = Length SP
This means the opposite sides are parallel and equal in length, hence it is a Parallelogram.

value of y when x equals -14.
-2x + 5y = 8
Answer:
y = -4
Step-by-step explanation:
-2x + 5y = 8
Let x=-14

Subtract 28 from each side
28-28 +5y = 8-28
5y = -20
Divide by 5
5y/5 = -20/5
y = -4

On a coordinate plane, 2 quadrilaterals are shown. Quadrilateral Q R S T has points (negative 1, 0), (5, 0), (3.5, negative 6) and (negative 2.5, negative 6). Quadrilateral Q prime R prime S prime T prime has points (negative 1, 2), (1, 2), (0.5, 0), and (negative 1.5, 0). Quadrilateral QRST is dilated and translated to form similar figure Q'R'S'T'. What is the scale factor for the dilation?
Answer:
[tex]\dfrac{1}{3}[/tex].
Step-by-step explanation:
In quadrilateral QRST, Q(-1,0), R(5,0), S(3.5,-6), T(-2.5,-6).
In quadrilateral Q'R'S'T', Q'(-1,2), R'(1,2), S'(0.5,0), T'(-1.5,0).
Distance formula:
[tex]D=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
Using distance formula , we get
[tex]QR=\sqrt{(5-(-1))^2+(0-0)^2}=\sqrt{6^2}=6[/tex]
[tex]Q'R'=\sqrt{(1-(-1))^2+(2-2)^2}=\sqrt{2^2}=2[/tex]
Now,
[tex]\text{Scale factor}=\dfrac{Q'R'}{QR}[/tex]
[tex]\text{Scale factor}=\dfrac{2}{6}[/tex]
[tex]\text{Scale factor}=\dfrac{1}{3}[/tex]
Therefore the scale factor is [tex]\dfrac{1}{3}[/tex].
The given transformation of quadrilateral QRST to quadrilateral Q'R'S'T'
are a dilation and a translation, therefore, QRST is similar to Q'R'S'T'.
[tex]\mathrm{The \ scale \ factor \ of \ the \ dilation\ between \ QRST \ and \ Q'R'S'T' \ is} \ \dfrac{1}{3}[/tex]
Reasons:
The vertices of the quadrilateral are;
Quadrilateral QRST
Q(-1, 0)
R(5, 0)
S(3.5, -6)
T(-1, 2)
Quadrilateral Q'R'S'T'
Q'(-1, 2)
R'(1, 2)
S'(0.5, 0)
T'(-1.5, 0)
The given transformation that gives quadrilateral Q'R'S'T' from quadrilateral QRST are a dilation and a translation.
Required:
The scale factor of the dilation
Solution:
[tex]\mathrm{The \ scale \ factor \ of \ the \ dilation} = \dfrac{\mathrm{Length \ of \ \overline{Q'R'} }}{\mathrm{Length \ of \ \overline{QR}} }[/tex]
Length of [tex]\overline{Q'R'}} }[/tex] = 1 - (-1) = 2
Length of [tex]\overline{QR}} }[/tex] = 5 - (-1) = 6
Therefore;
[tex]\mathrm{The \ scale \ factor \ of \ the \ dilation} = \dfrac{2}{6} = \dfrac{1}{3}[/tex]

ERRE
A rectangle on a coordinate plane is translated 5 units up and 3 units to the left. Which rule describes the translation?
O(x,y) - (x + 5, y-3)
(x,y) - (x + 5, y + 3)
O (x, y) - (x-3, y + 5)
O(x, y) - (x + 3, y + 5)
"translated 5 units up" means y becomes y+5. We just add 5 to whatever the y coordinate is to shift the point 5 units up.
To shift 3 units left, we subtract 3 from whatever the x coordinate value is. So we go from x to x-3.
Put this together and the translation rule is [tex](x,y) \to (x-3, y+5)[/tex]

The angles of a quadrilateral are in the ratio of 2:6:9:13
Find all the angles of the quadrilateral
Answer:
24° , 72° , 108° , 156°Step-by-step explanation:
Let the angles be 2x , 6x , 9x , 13x
We know that the sum of quadrilateral is 360°
Now,
[tex]2x + 6x + 9x + 13x = 360[/tex]
Calculate the sum
[tex]30x = 360[/tex]
Divide both sides of the equation by 30
[tex] \frac{30x}{30} = \frac{360}{30} [/tex]
Calculate
[tex]x = 12[/tex]
Replacing the value,
2x = 2 * 12 = 24°
6x = 6 * 12 = 72°
9x = 9 * 12 = 108°
13x = 13 * 12 = 156°
So, the angles are 24° , 72° , 108° , 156°
Hope this helps...

Answer:
Below in bold.
Step-by-step explanation:
2+6+9+13 = 30.
Now there are 360 degrees in a a quadrilateral.
So the value of the shortest angle = 2/30 * 360
= 1/15 * 360
= 24 degrees.
In the same way the value of the other 3 angles is:
6/30 * 360, 9/30 * 360 and 13/30 * 360
= 72, 108 and 156 degrees.

Step-by-step explanation:
you make x the subject of formula for all the questions.
a(x+b)=cfirstly you divide both sides of the equation by a, this way the a will cancel it self out of the equation
x+b= c/a
then you take '+b' to the other side of the equation over the = sign, this makes +b sign to change it then becomes -b
x=c/a -b
2. 7(x-a)=b
you divide both sides of the equation by 7.
x-a=b/7
then you take -a to the other side of the equation it becomes +a
x=b/7+a
