A line passes through the points (0, 2) and (1, 8). What is its equation in slope-intercept form?
Answer:
y=6x+2
Step-by-step explanation:
y=mx+b
-the y and x are variables and your going to want to leave them that way.
-m is the slope
-b is the y-intercept
after plotting your points and drwaing a line through them you get your final equation
What is the distance from X to Y?
A. 15 units
B. 3 units
C. 225 units
D. 21 units
Answer:
15, A
Step-by-step explanation:
(0,6) (9,-6)
distance formula =
[tex]d= \sqrt{(x_2-x_1)²+(y_2-y_1)² }[/tex]
lets put our numbers
[tex]d= \sqrt{(0 - 9)²+(6+ 6)² }[/tex]
so answer will be = 15, A
There is a box of cards in front of you with 9 heart cards, 4 spade cards, 7 club
cards, and 8 diamond cards. What is the probability of selecting a heart, not
replacing it, then selecting a spade, not replacing it, and on the third pick,
selecting a card that is not diamond? *
Answer:
heart cards 9/28
spade cards 4/27
diamond card 18/26
Step-by-step explanation:
you have 9 heart cards in all and 28 in all
take one heart out and not replacing you have 27
you have a 4/27 chance of getting spade because you have 4 spades out of 27 cards
now you have 26 cards from taking the one spade & heart out you have a 8/26 chance of getting diamond but a 18/26 chance of getting any other card

es perpendicular 3x+y-9=0 y pasa por el origen (0, 0).
Answer:
[tex]y = \frac{1}{3} x[/tex]
Step-by-step explanation:
Una recta que es perpendicular a la pendiente de una ecuación es la recíproco negativo. de l
a ecuación original.
Primero, este problema está en forma estándar, así que conviértalo a la forma de intersección de pendiente
[tex]3x + y - 9 = 0[/tex]
[tex]3x + y = 9[/tex]
[tex]y = 9 - 3x[/tex]
[tex]y = - 3x + 9[/tex]
Ahora encuentre el recíproco negativo de la pendiente que es -3x
[tex] \frac{ - 3}{1} [/tex]
[tex] - ( - \frac{3}{1} [/tex]
[tex] \frac{1}{3} [/tex]
La pendiente es 1/3, así que sepa que introduzca 0 para nuestro valor X para encontrar nuestro valor y
[tex]y = \frac{1}{3} x[/tex]
[tex]y = \frac{1}{3} (0)[/tex]
y=0

Answer:
(a)(b)=0.45
a/b=0.8
Step-by-step explanation:
a=0.6
b=0.75
(a)(b)=(0.6)(0.75)=0.45
a/b=0.6/0.75=0.8
Answer:
a*b = 0.5
a/b = 0.888...
Step-by-step explanation:
0.6666... = 2/3
a*b = 2/3 * 3/4 = 1/2 = 0.5
a/b = (2/3) / (3/4) = 8/9 = 0.888...

Answer:
answer in explanation
Step-by-step explanation:
Mean: 13
Median: 9
Mode: 9
Range: 28
The mean,median,mode and range of the data will be 13,9,9 and 28.
How to find the mean of a data set?Mean is the ratio of the sum of the values of the data set to the total number of values available in the data set.
Thus, we get;
[tex]\rm Mean = \dfrac{\text{Sum of the observations of the data set}}{\text{Total number of observations}}[/tex]
[tex]\rm Mean= \frac{3+25+9+30+9+2}{6} \\\\ Mean=13[/tex]
Arrange the data in the ascending order;
2,3,9,9,25,30
The median of the data set is;
[tex]\rm Median = \frac{9+9}{2} \\\\ Median =9[/tex]
Mode is the value appear most of the time in the data set;
9 is the number repeat two times in the data set.
Mode = 9
Range of the data is the difference of the maximum and the minimum value;
Range=30-2
Range=28
Hence,the mean,median,mode and range of the data will be 13,9,9 and 28.

What is a translation (math)
Answer:
Translation is a term used in geometry to describe a function that moves an object a certain distance. The object is not altered in any other way. It is not rotated, reflected or re-sized. In a translation, every point of the object must be moved in the same direction and for the same distance.
Step-by-step explanation:
Hope that helped :)
Answer:
"Sliding": moving a shape without rotating or flipping it.
The shape still looks exactly the same, just in a different place.
Step-by-step explanation:
In Euclidean geometry, a translation is a geometric transformation that moves every point of a figure or a space by the same distance in a given direction. A translation can also be interpreted as the addition of a constant vector to every point, or as shifting the origin of the coordinate system.

A rectangle has a length of (5x+2) and a width of (3x-7). Find the perimeter of the rectangle.
Answer:
Perimeter = 2(5x-2)+2(3x-7)
Step-by-step explanation:
The perimeter (P) of any rectangle can be represented in terms of length (L) and width (W) with the equation P=2L+2W.
You multiply the length and width of the rectangle by two, since it's only giving one expression for the length and width.
