what does i2x + 3(x - 5) = 20 equal

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.

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​.

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.

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.

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

Answer:

draw a straight line

draw a point and name it A

place your compass at A and expand it to draw an arc

Name point where arch meets the line B

place compass at B and draw arch to pass through the big arc

Draw a line through point of intersection to meet at A

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?

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

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.
