What number could make this equations have no value of x. 3x+8 = 3x + ?

Answers

Answer 1

Answer:

Answer:

All values of x :-

3x + 8 = 3x + 8 has Infinite solutions .

Just one value of X :-

3x + 8 = 3x + x is equal to 3x + 8 = 4x , which has one solution at x= 8 .

Step-by-step explanation:

I hope this helps you !!

Answer 2

Answer: ?= anything
this is because the slope is the slopes are the same in both equations so they will cancel each other.

A zoo keeper wants to fence a rectangular habitat for goats. The length of the habitat should be at least 80 feet, and the perimeter of the habitat should be no more than 300 feet. a. Write and graph a system of linear inequalities

b. Write two possible solutions:

Answers

In inequality system, for the zoo keeper fencing, the greater than sign used for at least word of habitat length and less then sign used for no more than word.

a) The system of inequalities for the given problem is,

$x\geq80$
$y\leq-x+150$
The graph which shows the inequalities of is attached below.
b) The dimensions for two possible solution are 90 ft by 20 ft and 110 ft by 30 ft.

What is linear inequality system?

Inequality equation is the equation in which the two expressions are compared with greater than, less than or other inequality signs. The system having linear inequality equations is called the linear inequality system.

Given information-

The length of the habitat should be at least 80 feet.

The perimeter of the habitat should be no more than 300 feet.

Suppose $x$ is the length of the rectangular habitat and $y$ is the width of the rectangular habitat.

As the length of the habitat should be at least 80 feet. Thus the value of $x$ should be more than or equal to the 80 feet. Therefore,

$x\geq80$

Perimeter of the rectangle is twice the sum of length and width. As the perimeter of the habitat should be no more than 300 feet. Thus,

$2(x+y)\leq300\n2x+2y\leq300\ny\leq-x+150$

Hence, the system of inequalities for the given problem is,

$x\geq80$

$y\leq-x+150$

The graph which shows the inequalities of is attached below.

As in the graph attached below shown the area which can be gives the solution for the given system. We take two points as, (90,20)and (110,30).

Thus the dimensions for two possible solution are 90 ft by 20 ft and 110 ft by 30 ft.

Hence,

a) The system of inequalities for the given problem is,
$x\geq80$
$y\leq-x+150$
The graph which shows the inequalities of is attached below.
b) The dimensions for two possible solution are 90 ft by 20 ft and 110 ft by 30 ft.

Calculate sin a=0.34

Answers

$sina=0.34$ has already been calculated for us, but to calculate the angle, which is what I'm assuming you want to know, we must take the inverse trigonometric function of sin.

From: $sina=0.34$ , we can derive that:

$a=sin ^(-1) 0.34$

Using a scientific calculator to solve this, we can see that the degrees that a is equal to (rounded to the nearest degree) is:

$a=20$ °

Dad is 4 times as old as his son Jim. In 10 years, Dad's age will be 20 years more than twice Jim's age. How old is Jim?If D = dad's age now and J = Jim's age now, which of the following systems could be used to solve the problem?

a. D = 4J and D + 10 = 2J + 20
b. D = 4J and D + 10 = 2(4J + 10) + 20
c. D = 4J and D + 10 = 2(J + 10) + 20

Answers

Let's focus on the "In 10 years" part

in 10 years
D will be (D + 10)
and J will be (J + 10)

"twice Jim's age" would then be 2(J + 10)
and
"20 years more than" that would be 2(J + 10) + 20

so
the answer with
D + 10 = 2(J + 10) + 20
would be your answer
that is, C.

Answer: The correct answer would be C:

Step-by-step explanation:

D=4J and D+10=2(J+10)+20

Monica made 1 red bracelet and 4 blue bracelets. She made twice as many black bracelets as red bracelets. She told her friend she made 7 bracelets. Was Monica's calculation reasonable?

A.
Yes, it is reasonable because 1 + 4 + 2 = 7.

B.
No, it is not reasonable because 1 + 4 + 5 = 10.

C.
No, it is not reasonable because 1 + 4 + 8 = 13.

Answers

The answer is A. twice as many black as red is twice as many as 1. So 1+2+4=7.
