How many solutions y=5x-4 y=5x-5
Answer:
No solution
Step-by-step explanation:
Any equations with the same slope are parallel, or will never intersect.
In a slope-intercept equation, this would mean the 'm' values are the same.
y = mx + b
Two equations:
y = 5x - 4
y = 5x - 5
Since the two equations given have the same slope, they will never intercept and therefore have no solution.
Q(2, a) is 5 units away from P(–2, –1). Find all possible values of a.
Answer:
a = 2
Step-by-step explanation:
Here, we want to find all the possible values of a
If Q is 5 units away from P, then the distance between Q and P is 5 units
Mathematically, to find the distance between two points, we use the following formula
D = √( (x2-x1)^2 + (y2-y1)^2
So we have ;
D = √(2-(-2)^2 + (a-(-1)^2
D = √(16) + (a + 1)^2
Since D is 5, we have
5 = √(16) + (a +1)^2
Squaring both sides to remove the square root, we have
25 = 16 + (a + 1)^2
(a + 1)^2 = 25 - 16
(a + 1)^2 = 9
(a + 1)^2 = 3^2
Since power is equal, equate base
a + 1 = 3
a = 3-1
a = 2

Ayuda con esto tengo muchos deberes y nececito terminarlos ahora, por favor ayuda :( .María y Nancy son vecinas, y todas estas semanas han realizado compras en el mercado. La semana pasada María gastó 25,75 dólares, exactamente 3 veces más de lo que gastó Nancy, que tenía poco que comprar. ¿Cuánto dinero se gastó Nancy?
Answer:
Nancy gastó 8,58 dólares.
Step-by-step explanation:
Para calcular cuánto dinero gastó Nancy, debemos hallar la relación entre Nancy y María, tal como sigue:
[tex] M = 3N [/tex] (1)
En donde M es por María y N por Nancy
En la relación de la equación (1) tenemos que el dinero que gastó María es 3 veces lo que gastó Nancy, tal como dice el enunciado.
Entonces, podemos hallar ahora cuánto gastó Nancy:
[tex] N = \frac{M}{3} = \frac{25,75}{3} = 8,58 [/tex]
Por lo tanto, Nancy gastó 8,58 dólares.

Translation !! keep getting random people Please only answer if u really know ! Thanks
Answer:
The direction matters , but only in sign... so from A to A' is what i'm guessing is the direction of translation
Step-by-step explanation:
find the vector from A to A' or any of the other non prime to prime points.. the vector will be the same... soooo
take the origin point as P1 , then take the destination point a P2
and subtract P2-P1
P2 = A' = (6,-2)
P1 = A = (2, 1)
(6-2, -2-1) = (4,-3)
your vector can be place at the origin.. and go 4 in the x direction and -3 in the y direction and you get that translation.. make sense?
Can you please help solve this problem Find m

The pre-image and image of what transformation are not congruent?
O A. dilation
O B. reflection
O C. translation .
O D. rotation
Answer:
Option A
Step-by-step explanation:
Options B, C, and D are examples of ridged transformations. Ridged transformations are transformations that keep the pre-image and image congruent.
A dilation would change the actual size of the pre-image to make the image, so they would be not congruent in a dilation.
Hope this helps.
The correct options are Reflection, Translation and Rotation.
What is transformation?A transformation is a general term for four specific ways to manipulate the shape and/or position of a point, a line, or geometric figure.
Reflection, Translation and Rotation are examples of rigid transformations, and we know that a rigid transformation is a transformation that doesn't change the size or shape of a geometric figure, a special kind of transformation that doesn't change the size or shape of a figure.
There are three different types of transformations: translation, reflection, and rotation.
Whereas,
A dilation would change the actual size of the pre-image to make the image, so they would be not congruent in a dilation, it can enlarge or shrink the image.
Hence, Reflection, Translation and Rotation are the transformation which preserve the preimage.

A shipping company sells a rectangular box with dimensions of 12
inches by 12 inches by 18 inches. Find the length of the longest
diagonal in the box.
24.7.
24.8
O 288
0 612
Answer:
24.7 inches
Step-by-step explanation:
Length = 18 inches
Width = 12 inches
Height = 12 inches
Length of the longest diagonal,d = length^2 + width^2 + height^2
d^2 = 18^2 + 12^2 + 12^2
d^2 = 324 + 144 + 144
d^2 = 612
d = √612
= 24.7 of inches
Length of the longest diagonal in the box = 24.7 inches

Xavier is driving home. He starts 250 miles from home and his car can travel 28 miles per gallon of gasoline he uses. Xavier stops at a rest stop that is 100 miles from home. Let g be the amount or gas he has used at that point. Set up and solve an equation for how much gas Xavier used to get to the rest stop.
Answer:
For 100 miles he uses 3.571 gallons of gasoline.
In equation form it is y/x*100
Step-by-step explanation:
Unitary Method
He travels 28 miles per gallon of gasoline.
For 1 mile he uses 1/28 gallons
For 100 miles he uses 1/28 * 100= 100/28= 3.571 gallons of gasoline.
Let x be the miles and y be the gallons of gasoline used to travel x miles.
Then for 1 mile the gallons of gasoline used will be y/ x gallons.
For 100 miles the gallons of gasoline used will be y/x *100 gallons.
In equation form it is y/x*100 gallons for 100 miles where x is the number of miles and y is the amount of gallons.
