Answer:

x=-8

Step-by-step explanation:

Multiply -4 by each number in the parenthesis ( distributive property )

Add x to -8x ( -7x )

Add 44 to 12 ( 56 )

Divide 56 and -7

 You should get x=-8

Answer:

No

Step-by-step explanation:

If you plug in the coordinates (4,2) to y=x-2 it will give you 2=2 which is rite, but if you plug it in to y=3x+4 it will give you 2=16 which isn't rite.

Answer:

always true

Step-by-step explanation:

Simplify, and if possible solve the equation to find out

remember, inverse operations

5x - 10 + 2x = 7 + 7x - 17

simplify both sides

7x - 10 = 7x - 10

this is an identity, no matter the value of x put in, the equation will be true,

hence the equation is always true

So the line is:

Answer:

y = -2/3 - 8/3a

Step-by-step explanation:

Find the slope using [ y2-y1/x2-x1 ]

6a-2a/-5a-a

4a/-6a

-2/3

Find the y-intercept.

y = mx + b

y = -2/3x + b

2a = -2/3(a) + b

-8/3a = b

y = -2/3 - 8/3a

Use the distance formula to determine the distance between two points.

Answer:

The distance is

d=√90

d=3√10

If you want to leave it in exact form, you can leave the distance as

. However, if you want the decimal answer, here it is rounded to the nearest hundredth's place:

d≈9.49

Answer:

Friend A pays $340 and friend B pays $510

Step-by-step explanation:

Let's call

x: payment of friend A

1.5x: payment of friend B

The sum of both payments must total $850, thus:

x + 1.5x = 850

Simplifying:

2.5x=850

x = 340

Now for friend B:

1.5x=1.5*340=510

Friend A pays $340 and friend B pays $510

Rational numbers are any of the following:

Irrational numbers are thus defined as:

This means that -8.7 is not irrational, as it is not an unending, non-repeating number: an easy way to remember how to answer this is to look at whether the number has been expressed in decimal form if it has (unless you have been told that it has been rounded) it must be rational, as it can be written as a decimal number.

Answer: 2

Step-by-step explanation:

count number a blocks it went up (4)

count number of blocks it goes to the right (2)

if it goes to the left or down the answer would have been negative

The statement radioactive nuclei are highly stable and emit radiation to become unstable is FALSE.

To determine if the statement is true or false we need to know what radiactivity is

Radioactivity is the spontaneous disintegration of unstable atomic nuclei to form stable more energetic nuclei with the emission of radiation.

Radioactivity includes the following

So, radioactive nuclei which are unstable emit radiation and become more stable.

So, the statement radioactive nuclei are highly stable and emit radiation to become unstable is FALSE.

Answer:

f(1) = 16

Domain: 0 ≤ t ≤ 2

Step-by-step explanation:

Given

f(t) = -16t²+ 32t

Solving (a): f(1)

Substitute 1 for t in f(t)

f(t) =− 16t²+ 32t .

f(1) =− 16 * (1)²+ 32 * 1

f(1) = -16 * 1 + 32

f(1) = -16 + 32

f(1) = 16

Solving (b): The domain

The implication of the given parameter in (b) is that t ≤ 2.

Since t represents time, t can't be negative.

Hence, a reasonable domain is

0 ≤ t ≤ 2
