Find the slope of the line shown on the graph to the right

Answers

Answer:

1

Step-by-step explanation:

We need two points to find the slope

( -1,0) and ( 2,3)

We can use the slope formula

m = ( y2-y1)/(x2-x1)

   = ( 3-0)/(2 - -1)

  = (3-0) / ( 2+1)

  = 3/3

  = 1

The slope is 1

What is the equation of the line passing through points (1.1) and (3.-5)

Answers

Answer:

Step-by-step explanation:

Any line has an equation ax+by+c=0 with some constants a, b and c. Because your line passes through the points (-1,1) and (3,5), you have two equations, -a+b+c=0 and 3a+5b+c=0. If you find a solution to these equations, you will find an equation of your line.

A fair six-sided dice is rolled once. What is the probability that a 2 is shown?

A) 1/2 B) 0.2 C) 1/6 D) 6% E) 2:1 ​

Answers

Answer:

C: 1/6

Step-by-step explanation:

There is one 2 on a six sided die. Therefore there is a 1/6 chance that it was a 2.

Answer:
1/6

Explanation:
It would be 1/6 because the fair is six-sided and the denominator is always how much of it is.

Cnidarians are another major group of invertebrates. Jellyfish, coral, hydra and anemone are examples of cnidarians. They have soft bodies and no heads. They have stinging tentacles that they use for defense and to capture prey. Cnidarians have radial symmetry. That means that their parts are arranged around a center. If you were to draw a line to cut them in half in any direction, the two sides will always match. Radial symmetry is often a characteristic of more simple animals than bilateral symmetry, where there is only one line you could draw to make two sides match. With bilateral symmetry, different body parts may have different functions. With radial symmetry, the entire body may perform all life functions.

Jellyfish do not have (what?)

a. heads.
b. tentacles.
c. symmetry.
d. soft bodies.

Answers

a. heads


A jellyfish has no ears or eyes or nose and no brain or heart. They do not even have a head as their body is almost totally made of water and is soft having no bones at all.

what is a -210 Divided by 14

Answers

Answer:

-15

Step-by-step explanation:

Well you cleary just divide the numbers But if you dont belive it use a caculator for this

-210 divided by 14 equals -15.

To divide -210 by 14, we set up the division equation: -210 ÷ 14.

Since we have a negative dividend, we know the quotient will also be negative.

We divide the absolute values of the numbers: 210 divided by 14, which equals 15.

Since the dividend and divisor have different signs, the quotient is negative.

Therefore, -210 divided by 14 equals -15.

This means that -210 can be evenly divided into 14 groups, each having a value of -15.

The negative sign indicates that the result is in the opposite direction or orientation compared to the positive value.

Jade has $22 to spend at the grocery store. He is going to buy bags of Takis that cost $4 each and one box of Oreos that costs $3.50. Write and solve an inequality that models this situation, and could be used to determine the maximum number of bags of takis, t, that Jade can buy.

Answers

Answer:

4 bags of takis

Step-by-step explanation:

take the $22 and subtract the $3.50 for the oreos, this leaves you with $18.50.

now, take the $18.50 and divide that by $4 (the amount takis cost) and you will find out how many bas he will he able to buy.

18.50/4 = 4.6 he will be able to buy only 4 bags and will have $2.50 left over

What is the value of x ?

Answers

Each angle of the triangle added together must be equal to 180, so 53+45=98. 180-98=82. So the top angle is 82, the value of x has to be equal to 180-82 which equals 98

For f(x) = -5x + 4, what is the value of x for which f(x) = 29?

Your answer:

x = 1


x = -5


x = 5


x = -4

Answers

Answer:

x=-5

Step-by-step explanation:

f(-5)=-5(-5)+4

*negative multiplied by a neative is a positive*

f(-5)=25+4

f(-5)=29

You can just plug in every number in to the formula unit you get 29 like this
F(x)=-5(1)+4= -1.
F(x)=-5(-5)+4= 29. ANSWER
F(x)=-5(5)+4= -21.
F(x)=-5(-4)+4= 24.

The solution to the given system of equations will be (0, -1). which is the correct option (B).

What is the Linear equation?

A linear equation is defined as an equation in which the highest power of the variable is always one.

The system of linear equations y = 2 x minus 1 and y = negative 4 x minus 1 which is given in the question.

y = 2x - 1     ....(i)

y = -4x - 1   ....(ii)

Substitute the value of equation (i) in equation (ii) and solve for variable x :

2x - 1 = -4x - 1

Rearrange the terms of variable "x" and combine them,

2x + 4x = -1 + 1

6x = 0

x = 0

Substitute the value of x = 0 in equation (ii) and solve for variable y :

y = -4(0) - 1

y = -1

Therefore, the solution to the given system of equations will be (0, -1).

Given hexagon LMNOPQ is congruent to hexagon L'M'N'O'P'Q'. What is the measure of OP?

6 in
7 in
45 in
51 in

Answers

Answer:

51in

Step-by-step explanation:

Just set the equations of line OP and line O'P' equal to one another, then solve for x.

ie: 3(2x+3)=(8x-5)

To solve for x, distribute first. Then, subtract 6x from each side. Then, add 5 to each side.

ie: 6x+9=8x-5

ie: 14=2x

Now divide by 2.

ie: 7=x

Now that you have your x value, plug it back into one of the equations and solve for the measure of line OP. To check you answer, plug 7 for x into the equation where they are set equal, then solve them both and if the end result is true (51=51) it is correct.
