1. Solve the following equation.(MAFS.8.EE.3.7)

5(3x + 7) + 2x = 7x – 5(–2x + 9)

Answers

Answer 1

Answer:

there is no solution

Step-by-step explanation:

Expand.

15x+35+2x=7x+10x-4515x+35+2x=7x+10x−45

2 Simplify  15x+35+2x15x+35+2x  to  17x+3517x+35.

17x+35=7x+10x-4517x+35=7x+10x−45

3 Simplify  7x+10x-457x+10x−45  to  17x-4517x−45.

17x+35=17x-4517x+35=17x−45

4 Cancel 17x17x on both sides.

35=-4535=−45

5 Since 35=-4535=−45 is false, there is no solution.

No Solution

The new coordinates of the point will be (7, 8)

What are coordinates?

A pair of numbers called coordinates are used to locate a point or a form in a two-dimensional plane. The x-coordinate and the y-coordinate are two numbers that define a point's location on a 2D plane.

Given, the new position of the given point (7, 4) has been achieved after the translation of 4 units up

Since translation upward in the cartesian plane means it is moving along the y-axis and hence its y-coordinate is changed. So, if a point is translated units up, its y-coordinate increases by a unit, and for a point (x,y), it changes to (x,y+a)

Thus,

The new coordinates of the point will be = (7, 4 + 4)

The new coordinates of the point will be = (7, 8)

What is function?

A function is represented as a rule that produces a distinct result for each input x. In mathematics, a function is indicated by a mapping or transformation. Typically, these functions are identified by letters like f, g, and h. The collection of all the values that the function may input while it is defined is known as the domain. The whole set of values that the function's output can produce is referred to as the range. The set of values that might be a function's outputs is known as the co-domain.

Given function:

f (x) = 3x – 1.

Also,

x        f(x)

-5       a

-2       7

4        b

8       c

Now, using the proportionality

k = y/x

k = 7 / (-2)

k = -3.5

So, -3.5 = a/ (-5)

-3.5 x (-5) = a

a= 17.5

again, -3.5 = b/4

b= -14

Lastly, -3.5 = c/8

c= -28.

Hence, the value of a= 17.5, b=-14 and c=-28.

Tom bought 9 new baseball trading cards to add to his collection. The next day his dog ate half of his collection. There are now only 28 cards left. How many cards did Tom start with ?

Answers

Tom started with 47 cards.

He had 28 left. If his dog ate half then multiply 28 by 2

You get 56

Out of those 56 cards, 9 of them are new

So subtract 9 from 56

You get 47

Tom started with 47 cards

28+28=56

9 are new so 56 - 9 = 47 which is your answer
